Notes on the genus Caiophora (Loasoideae, Loasaceae) in Chile and neighbouring countries
Provedor de dados: 66
Autores: Ackermann,Markus; Weigend,Maximilian.
This is the first revision for the representatives of the genus Caiophora (Loasaceae) in Chile. The genus is widely distributed in the Andes from Argentina/Chile in the South to Central Ecuador in the North, and comprises approximately 60 species. In Chile only five species are present, Caiophora chuquitensis, C. cirsiifolia, C. coronata, C. deserticola sp. nov. and C. rosulata. Caiophora rosulata is here subdivided into two subspecies: western Andean C. rosulata subsp. rosulata (present in northern Chile and southern Peru), and eastern Andean C. rosulata subsp. taraxacoides, stat. and comb. nov. Furthermore C. superba syn. nov. and C. macrocarpa syn. nov. are placed into synonymy under C. chuquitensis, and C. rahmeri syn. nov. is synonymized to C....

Autores: Silva-Filho,Alexandre Gonçalves dos Santos; Teixeira-Silva,Márcia de Araújo; Cortez,Vagner G.
In a survey of Agaricales fungi in Seasonal Semidecidual Forest remnants from Paraná State, southern Brazil, two Clitocella and two Rhodocybe species were identified. Based on morphological data, Clitocella pallescens is described as a new species, and a new combination is proposed to Clitocella himantiigena. Rhodocybe galerinoides and C. himantiigena are new records from Brazil. Rhodocybe caelatoidea, already registered in Paraná State, is also described, illustrated and discussed.

Autores: Ulibarri,Emilio A.
The South American flora includes 65 genera of Caesalpinioideae (Leguminosae) with wide morphological variation. The four tribes of that subafmily are represented: 31 genera belong to the Caesalpinieae (3 of them introduced); 9 to the Cassieae; 2 to Cercideae (1 introduced), and 23 to Detarieae (2 introduced). Among the South American Caesalpinoideae, 30 genera are endemic (mainly to Brazil), the remaining ones inhabit in tropical and subtropical areas from both hemispheres. All of them grow in diverse habitats: from rainforests, evergreen or deciduous forests, to savannas, semideserts and high mountains. Tribes and genera are arranged according to Polhill &amp;amp; Raven (1981), only Poepiggia has been transferred from Caesalpinieae to Cassieae, and...

The generic affinity of Caiophora pulchella (Loasaceae, Loasoideae)
Provedor de dados: 66
Autores: Acuña Castillo,Rafael; Weigend,Maximilian.
The history of the nomenclatural changes and past hypotheses on the relationships of Caiophora pulchella are presented. The identity of voucher specimens, identified as C. nivalis in previous phylogenetic studies, is reassessed based on fruit morphology. The validity of C. pulchella is reconsidered and can be confirmed as a member of the genus Caiophora based on both morphological and molecular data. Alternative generic placements are rejected.

Provedor de dados: 69
Autores: Ali,Ghulam M; Yasumoto,Sirato; Seki-Katsuta,Masumi.
Sesame (Sesamum indicum L.) is one of the oldest oil crops and is widely cultivated in Asia and Africa. To determine the level of genetic diversity in relation to geographical origins and morphological characteristics, a total of 96 accessions have been collected from different parts of the world and were analyzed using AFLP techniques. Twenty-one primer pairs generated a total of 445 bands and among them 157 (35%) were polymorphic. Using UPGMA clustering analysis method based on the similarity coefficient, accessions were separated into two major groups. The first group mostly consists of Eastern Asian origin and another group consists of South Asian origin. Sub-clusters separated the accessions and form distinct diversity among groups. Considering the...

Provedor de dados: 69
Autores: Naing,Aung Htay; Ai,Trinh Ngoc; Jeon,Su Min; Park,Kyeung Il; Lim,Ki Byung; Kim,Chang Kil.
Background Several MYB genes belonging to R2R3 MYB transcription factors have been used in several plant species to enhance anthocyanin production, and have shown various expression or regulation patterns. This study focused on the effect of ectopic expression of an RsMYB1 isolated from radish (Raphanus sativa) on chrysanthemum cv. ‘Shinma'. Results The RT-PCR results confirmed that RsMYB1 regulated the expression of three key biosynthetic genes (CmF3H, CmDFR, and CmANS) that are responsible for anthocyanin production in transgenic chrysanthemum, but were not detected in the non-transgenic line. In all transgenic plants, higher expression levels of key biosynthetic genes were observed in flowers than in leaves. However, the presence of RsMYB1 in...

NEW RECORDS OF HATCHERIA MACRAEI (SILURIFORMES, TRICHOMYCTERIDAE) FROM CHILEAN PROVINCE
Provedor de dados: 72
Autores: Unmack,Peter J; Habit,Evelyn M; Johnson,Jerald B.
We describe collections oiHatcheria macraei (Patagonian catfish) from south-central Chile. This represents a significant range extension for this species. These new records have important biogeographic implications as H. macraei is now recorded within Chilean Province, far north of its previous distributional limit in Patagonian Province. We document a new character, the shape of the dorsal fin, which allows quick and easy discrimination between H. macraei and Trichomycterus areolatus in the field or laboratory. This study highlights the need for careful identification for trichomycterid catfishes from southern Chile.

Provedor de dados: 72
Autores: Peluffo,Julio; Moly de Peluffo,María C.; Rocha,Alejandra M.
Numerous specimens of Echiniscus rufoviridis (Heterotardigrada, Echiniscidae) were recorded and studied from urban localities in Argentina. Since the first description of this species by &lt;A HREF="#DuBois-Raymond"&gt;Du Bois-Raymond Marcus in 1944&lt;/A&gt; on Brazilian specimens, it had not been recorded again. The validity of the species is confirmed, its geographic distribution is extended to Argentine localities and new data are provided on its morphology (optical and SEM) and its bioecology. Echiniscus rufoviridis can be clearly separated from the E. viridis, the closest species within the "viridis group", by the possession of depressions with pores on the surface of the cuticle, instead of papillae. On the other hand, an ecological similarity with...

COMPARATIVE FOLIAR EPIDERMAL MORPHOLOGY OF THE WEST AFRICAN SPECIES OF THE GENUS AFZELIA SMITH (LEGUMINOSAE: AESALPINIOIDEAE)
Provedor de dados: 73
Autores: Babalola Kadiri,Akeem; Dele Olowokudejo,James.
The epidermal features of the leaves of the six West African species of Afzelia were examined and compared using light and scanning electron microscopy. The leaves are hypostomatic in all species and stomatal type is paracytic. Anticlinal walls may be undulate or straight-curved and stomatal index ranges from 17.48% in A. bella var. gracilior to 25.20% in A. bipindensis. Porrect and flattened scales distinguish the infra-specific taxa of A. bella while presence of unicellular trichomes separates A. pachyloba from other species. The leaf surface is entirely covered by epicuticular wax deposits and the stomata are either raised or sunken in the genus. Using these foliar epidermal characters, an artificial key has been prepared to facilitate identification of...

Autores: Machado,Taís; Silva,Maria José de J.; Leal-Mesquita,Emygdia Rosa; Carmignotto,Ana Paula; Yonenaga-Yassuda,Yatiyo.
Spiny rats of the genus Proechimys are morphologically diverse, widely distributed and have diploid numbers ranging from 2n = 14-16 to 2n = 62. In this paper we present cytogenetical data and brief comments on morphological and biogeographical issues related to spiny rats. In our sample of 42 spiny rats collected from 12 Brazilian Amazonian tropical rainforest and the Cerrado (Brazilian savanna) sites we detected nine karyological entities: four different karyomorphs with 2n = 30, three with 2n = 28, one with 2n = 15 and one with 2n = 44. Based on qualitative morphological characters these karyomorphs can be allocated to five species within the goeldii, guyannensis and longicaudatus species groups.

Autores: Gnasekaran,Pavallekoodi; Mahmood,Maziah; Subramaniam,Sreeramanan.
ABSTRACT Growing orchids has been classified as an international business since it covers 8% of the world floriculture trade. Thus, large-scale micropropagation of orchid using tissue culture techniques and improvement of some essential traits, such as resistances to various diseases and pests, and tolerances to environmental stresses, such as low temperatures and low light intensities, via genetic engineering acknowledged the orchids as one of the top ten cut flowers. Protocorm-like bodies (PLBs) are excellent explants for clonal propagation, artificial seeds development and genetic engineering since they are organized and easily regenerable somatic embryos that propagate rapidly. Vanda Kasem's Delight hybrid orchid's PLBs derived from shoot tip culture...

Cytochemical study of Rhodnius neglectus and Rhodnius prolixus salivary gland cells (Hemiptera, Triatominae)
Provedor de dados: 76
Autores: Anhê,Ana C. B. M.; Lima-Oliveira,Ana P. M.; Azeredo-Oliveira,Maria T. V.
Triatomines are hematophagous bugs of medical interest in South and Central America, where they may act as invertebrate hosts of the hemoflagellate protozoa Trypanosoma cruzi (the causative of Chagas’ disease) and Trypanosoma rangeli (Tejera, 1920). Triatomines of Rhodnius genus have salivary gland formed by two close and independent units: the principal and the accessory. This gland secretes saliva that abounds in substances that facilitate and permit feeding. Despite this importance, there are few reports on its cytochemistry. In purpose of amplifying this understanding, in this work it was investigated the nuclear structures (chromatin and nucleolar corpuscles) of salivary gland cells of Rhodnius neglectus (Lent, 1954) and Rhodnius prolixus (Stål,...

Provedor de dados: 76
Autores: Silva,Daniela de M. e; Cruz,Aparecido D. da; Bastos,Rogério P.; Telles,Mariana P. de C.; Diniz-Filho,José Alexandre F.
To assess genetic structure and phenotypic diversity of Eupemphix nattereri Steindachner, 1863, morphometric and molecular analyses were carried out for nine populations from the State of Goiás. A total of 11 morphometric traits were evaluated and genetic information was estimated using RAPD markers. Genetic and phenotypic distances were determined as a function of geographical origin. Correlation among genetic, morphometric, micro, and macroenviromental were analyzed by the Mantel test. Genetic data indicated high levels of genetic diversity (Φst= 0.3) among the nine populations. Mantel tests did not reveal a significant positive correlation between genetic and geographical distances, indicating that locally geographical populations were not genetically...

Geographic distribution and morphological variation in Mimon bennettii (Chiroptera, Phyllostomidae)
Provedor de dados: 76
Autores: Gregorin,Renato; Capusso,Guilherme L.; Furtado,Vanessa R.
We studied discrete and quantitative data from 88 specimens of the subgenus Mimon previously identified as Mimon bennettii (Gray, 1838) and M. cozumelae Goldman, 1914 from diverse parts of their range. Our data indicate that specimens of Mimon bennetii in Brazil presented geographic variation in morphometrical characters and mosaic variation in qualitative traits. Specimens from the Cerrado biome collected in Brazilian states like Piaui, Tocantins, and Goiás have longer forearms than those distributed in the Atlantic and Amazon forested domains. Based on morphometrics, as showed by t-tests, specimens of M. bennettii from the Brazilian Cerrado resemble phenetically more with M. cozumelae than the M. bennettii from Atlantic Forest. Characters presently used...

Autores: Novais,Renata F.; Siciliano,Salvatore; Emin-Lima,Renata; Silva Júnior,José S.
ABSTRACT This study aimed to investigate the ontogenetic development of the skull in the Guiana dolphin (Sotalia guianensis Van Bénéden, 1864 ) through the comparison of 29 morphological non-metrical characters together with the estimated age of 54 specimens derived from four areas on the northern coast of Brazil. The state of each character was associated with the age of each specimen to assess the formation of bone structures, and the degree of fusion of the sutures in each state of the character studied. Nineteen qualitative morphological characters presenting state ontogenetic variations have been analyzed statistically. The analysis depicted that the characters associated with the parietal-frontal suture, parietosupraoccipital, parietoexoccipital,...

Autores: Miyoshi,Akio R.; Gabriel,Vagner A.; Fantazzini,Evandro R.; Fontanetti,Carmem S.
The aim of this paper is to report the morphology and distribution of microspines in diplopods pylorus, as these are important structures present along the alimentary tract of arthropods. The morphology of the internal surface of the pylorus of Pseudonannolene tricolor Brolemann, 1901 and Rhinocricus padbergi Verhoeff, 1938 was analyzed by SEM. Pseudonannolene tricolor presents two morphologically distinct pyloric regions: anterior and posterior. The first region is characterized by the presence of thin microspines that increase in number and size towards the posterior portion; the second region presents smaller and triangular-shaped microspines distributed throughout small plates. The pylorus of R. padbergi does not present differentiated regions; the...

Crustáceos no cerrito Ariano Souza, Rio Grande, Rio Grande do Sul e distribuição de Callinectes sapidus (Brachyura, Portunidae)
Provedor de dados: 76
Autores: Santos,Cléverson Ranniéri M. dos; D'Incao,Fernando.
While all species of the genus Callinectes Stimpson, 1860 have a continuous distribution on the Atlantic coast of the Americas, Callinectes sapidus Rathbun, 1896 is the only one with disjunct distribution. Considering that this species was introduced in Europe and Japan, it has been suggested that the occurrence of C. sapidus on the southern coast of Brazil was due to the transport by ballast water. In the archaeological site Ariano Souza, located in the estuary of the Patos Lagoon (southern Brazil), remains of crustaceans, including claws of approximately two thousand years ago, were found. A preliminary analysis of this material showed Callinectes chelae. Because this archaeological site is located inside the estuary, it has been hypothesized that these...

Evolution of Blennioidel in the Mediterranean Sea
Provedor de dados: 5
Autores: Zander, C. Dieter.
The evolution of 2 spp belonging to the gen Tripterygion and some spp of the gen Blennius is discussed. Tripterygion tripteronotus and T. xanthosoma have very similar morphological characters yet live in 2 distinct niches. This probably results from 2 separate immigrations into the Mediterranean at different eras after the glacial age. After establishing reproductive barriers these populations would have evolved into 2 distinct spp. In contrast the spp of the gen Blennius were endemic in the Mediterranean and their evolution must have taken place after the end of the glacial age. During this lapse of time, multiple differentiations which might have taken place would account for the presence of sibling spp having comparable morphological characters but...

Resolving the Ophioderma longicauda (Echinodermata: Ophiuroidea) cryptic species complex: five sisters, three of them new
Provedor de dados: 5
Autores: Stöhr, Sabine; Weber, Alexandra; Boissin, Emilie; Chenuil, Anne.
The conspicuous Mediterranean brittle star Ophioderma longicauda (Bruzelius, 1805) has been discovered to represent a cryptic species complex, consisting of six nuclear clusters with contrasting reproductive modes (broadcast spawners and brooders). Here, O. longicauda is re-described. It is distinguished by a dark reddish-brown colouration both dorsally and on the ventral disc, and multiple tumid dorsal arm plates. One eastern Mediterranean brooding cluster is described as O. zibrowii sp. nov., characterized by a dark olive-green colour both dorsally and on the ventral disc, and single dorsal arm plates. Another brooder is described from Tunisia as O. hybrida sp. nov., with a highly variable morphology that reflects its origin by hybridization of...

New genera and species from the Equatorial Pacific provide phylogenetic insights into deep-sea Polynoidae (Annelida)
Provedor de dados: 5
Autores: Bonifacio, Paulo; Menot, Lenaick.
Polynoidae contains ~900 species within 18 subfamilies, some of them restricted to the deep sea. Macellicephalinae is the most diverse among these deep-sea subfamilies. In the abyssal Equatorial Pacific Ocean, the biodiversity of benthic communities is at stake in the Clarion-Clipperton Fracture Zone (CCFZ) owing to increased industrial interest in polymetallic nodules. The records of polychaetes in this region are scarce. Data gathered during the JPI Oceans cruise SO239 made a significant contribution to fill this gap, with five different localities sampled between 4000 and 5000 m depth. Benthic samples collected using an epibenthic sledge or a remotely operated vehicle resulted in a large collection of polynoids. The aims of this study are as follows:...

Mass-transport deposits on the Algerian margin (Algiers area): morphology, lithology and sedimentary processes
Provedor de dados: 5
Autores: Dan, Gabriela; Sultan, Nabil; Cattaneo, Antonio; Deverchere, J; Yelles, K.
On 21st May 2003, a damaging earthquake of Mw: 6.9 struck the region of Boumerdès 40 km east of Algiers in northern Algeria. The seismic shocks had devastating effects in the offshore area between the cities of Algiers and Dellys, where numerous cable breaks were observed. The submarine area encompassing the 2003 Boumerdès epicenter (central Algerian margin) was recently investigated using geophysical and sampling tools. It has been observed that small-size slides and mass-transport deposits occur across this area. Thus, a detailed analysis was performed on 25 submarine slides identified in water depth from 500 m to 2700 m, by measuring different morphological parameters (i.e. surface, head-scarp height, slope in the source area and in adjacent...

Sedimentation on intertidal mudflats in the lower part of macrotidal estuaries: Sedimentation rhythms and their preservation
Provedor de dados: 5
Autores: Deloffre, J; Verney, Romaric; Lafite, R; Lesueur, P; Lesourd, S; Cundy, A.
The objective of this study is to propose an original approach to the analysis of the formation of intertidal rhythmites, their preservation, and the evaluation of sedimentation rates on estuarine mudflats. Three mudflats, one from each of three estuaries, were analysed using a combination of long-term (&gt;a year), high-frequency (1 burst/10 or 20 min), and high-resolution (0.2 cm) altimeter datasets and X-ray images of sediment cores collected during topographic surveys. The results highlight the roles played by sediment supply, hydrodynamics, and morphology of the lower estuaries on the sedimentation rhythms. While the sediment-starved Medway estuary (Kent, UK) remains stable at different time-scales, the annual sedimentation rates on the sheltered...

Toxoglossate marine gastropods, traditionally assigned to the families Conidae, Terebridae, and Turridae, are one of the most populous animal groups that use venom to capture their prey. These marine animals are generally characterized by a venom apparatus that consists of a muscular venom bulb and a tubular venom gland. The toxoglossan radula, often compared with a hypodermic needle for its use as a conduit to inject toxins into prey, is considered a major anatomical breakthrough that assisted in the successful initial radiation of these animals in the Cretaceous and early Tertiary. The pharmacological success of toxins from cone snails has made this group a star among biochemists and neuroscientists, but very little is known about toxins from the other...

Ailadinium reticulatum gen. et sp. nov. (Dinophyceae), a New Thecate, Marine, Sand-Dwelling Dinoflagellate from the Northern Red Sea
Provedor de dados: 5
Autores: Saburova, Maria; Chomerat, Nicolas.
A new photosynthetic, sand-dwelling marine dinoflagellate, Ailadinium reticulatum gen. et sp. nov., is described from the Jordanian coast in the Gulf of Aqaba, northern Red Sea, based on detailed morphological and molecular data. A. reticulatum is a large (53–61 μm long and 38–48 μm wide), dorsoventrally compressed species, with the epitheca smaller than the hypotheca. The theca of this new species is thick and peculiarly ornamented with round to polygonal depressions forming a foveate-reticulate thecal surface structure. The Kofoidian thecal tabulation is APC (Po, cp), 4′, 2a, 6′′, 6c, 4s, 6′′′, 1p, 1′′′′ or alternatively it can be interpreted as APC, 4′, 2a, 6′′, 6c, 4s, 6′′′, 2′′′′. The plate pattern of A. reticulatum is noticeably different from...

A new deep-sea genus of nannastacidae (Crustacea, cumacea) from the lucky strike hydrothermal vent field (Azores triple junction, mid-atlantic ridge)
Provedor de dados: 5
Autores: Corbera, J; Segonzac, Michel; Cunha, M.
A new cumacean genus and species, Thalycrocuma sarradini gen. et sp. nov., belonging to the family Nannastacidae is described from several sites of the Lucky Strike hydrothermal vent field (Mid-Atlantic Ridge, 37N, 1700 m depth). The new genus differs from others in the family by males lacking exopods on the pereopods 3 and 4 and having an antenna with a five-articulate peduncle and a short flagellum. This is the first cumacean species that could be considered, at the moment, as endemic from hydrothermal vent areas. Data on the accompanying fauna including other cumacean species (Cyclaspis longicaudata, Bathycuma brevirostre, Procampylaspis sp. and Makrokylindrus sp.) and some ecological remarks are included. A key for the currently known genera of the...

Consequences du cycle de mue et d'intermue sur la morphologie fonctionnelle des pars molaris des Crustaces Peracarides.
Provedor de dados: 5
Autores: Saudray, Yves.
The anatomy of the masticatory part of the mandible (the pars molaris) has been studied throughout the moult/intermoult cycle in some peracacarid crustacean species, by scanning electron microscopy. Species examined were: Ligia oceanica, Sphaeroma serratum, Idotea balthica, Talitrus saltator, Hyale nilssoni, Gammarid amphipoda and the mysid Pranus flexuosus. Feeding is known to decline near moulting; this may be because the chewing surfaces become loosened before moulting. Also the surfaces are worn down and useless, and feeding ceases. Very long intermoult periods, as found in old individuals, may thus cause long periods of starvation and this could enhance the symptoms of senescence.

Autores: Shin, Hyeon Ho; Li, Zhun; Mertens, Kenneth; Seo, Min Ho; Gu, Haifeng; Lim, Weol Ae; Yoon, Yang Ho; Soh, Ho Young; Matsuoka, Kazumi.
In Japanese, Chinese and Korean coastal waters, recurrent blooms of a small, elongate Prorocentrum species have been observed in recent years. In previous studies, this species has been respectively identified as P. shikokuense, P. donghaiense and P. dentatum, despite morphological similarity and identical rDNA sequences. To resolve the confusion, morphological features, including the architectural details of the periflagellar area, were examined and ribosomal DNA (rDNA) sequences were obtained from specimens collected from the East China Sea and Korean coast, and a strain established in the waters off the Canary Islands of Spain. In addition, the descriptions of the three species and allied species were reviewed. Morphological observations and a phylogeny...

In 2000 Ifremer launched and coordinated the development of a monitoring strategy for the REBENT network (REseau BENThique) in order to assess the aftermath of the “Erika” oil spill which took place in December 1999. Its aim is to provide consistent baseline knowledge on coastal benthic habitats, as well as to develop a monitoring tool that detects changes at various spatial and temporal scales. Sector-based seabed habitat mapping in shallow water (&lt; 50 m deep), is currently being conducted throughout Brittany's coastal waters using a combination of geoacoustic marine systems together with ground-truthing using biological grab sampling and seabed observations.  Due to the extended area, the overlap of soft and rocky bottoms, and contrasting hydrological...

Facteurs de contrôle sur le fonctionnement du système turbiditique du Rhône depuis le Dernier Maximum Glaciaire
Provedor de dados: 5
Autores: Lombo Tombo, Swesslath.
Turbidite systems are accumulations of fluvial sediment on the continental margins. They are mainly made of « turbidites » deposited after the flow of turbidity currents inside submarine canyons and channels. Their structure and composition are controlled by global and regional environmental changes such as sea level and climate. The two fundamental parameters that govern their functioning are the production of sediment in the river watersheds and the capability and reactivity of the transfer to the turbidite system. In this work we show that for the last 24,000 years the functioning of the Rhone turbidite system has shown rapid changes under the control of sea level and sediment production fluctuations. Our results are based on a millennial time-scale...

Autores: Lastras, Galderic; Canals, M; Amblas, D; Ivanov, M; Dennielou, Bernard; Droz, Laurence; Akhmetzhanov, A.
After obtaining full-coverage swath bathymetry data in 1995 and very high-resolution acoustic profiles in 2002, four slides at the Balearic Margin of the Eivissa Channel in the western Mediterranean Sea were revisited in 2004 when side-scan sonar data were collected using a MAK-1M deep-towed acoustic system. These new findings, higher in resolution than those for the swath bathymetry, show two main features previously undetected within these submarine landslides: (1) a series of step-forming inclined and detached slabs oriented perpendicular to the slide movement and located in the uppermost part of the slides, and (2) arcuate regular positive ridges oriented also normal to the slide movement and located in the depositional lobes of some of the slides.

A small Prorocentrum species was found during a pilot taxonomic survey of marine benthic dinoflagellates in the northwestern Arabian Sea, Oman. Based on the study of cells from natural samples and laboratory cultures using light and scanning electron microscopy, this taxon is attributed to the little-known Prorocentrum sipadanense, recorded so far only from East Malaysia. The description of this species has been emended to include details of internal cell structure, composition of its periflagellar area and intraspecific variability in size, shape and pore pattern. Round to oval or ovoid cells of P. sipadanese are surrounded by a prominent marginal ridge and are 17.9–23.9 µm long and 15.0–19.8 µm wide, with a foveate to reticulate thecal plate surface and...

Fortnightly tidal asymmetry inversions and perspectives on sediment dynamics in a macrotidal estuary (Charente, France)
Provedor de dados: 5
Autores: Toublanc, Florence; Brenon, Isabelle; Coulombier, T.; Le Moine, Olivier.
Tidal asymmetry is a phenomenon that characterises estuarine hydrodynamics and has a strong impact on sediment dynamics. Extensive research has been dedicated to studying tidal dynamics in semidiurnal macrotidal estuaries, highlighting several general principles. The ratio of flood to ebb peak velocities and differences in ebb and flood durations are often used to characterise the asymmetry encountered in estuaries. In the Charente estuary (French Atlantic coast), water surface elevation data obtained using an ADCP (Acoustic Doppler Current Profiler) and a tide gauge show that the duration asymmetry undergoes inversions during the spring-neap tidal cycle. A two-dimensional hydrodynamics model is used to investigate the connection between spring-neap...

Autores: Triki, Habiba Zmerli; Laabir, Mohamed; Moeller, Peter; Chomerat, Nicolas; Daly-yahia, Ons Kefi.
The dinoflagellate Alexandrium pseudogonyaulax is widely distributed around the world including the Mediterranean waters. The objectives of this study were to determine the morphology and phylogenic affiliation of A. pseudogonyaulax strain isolated from Bizerte Lagoon (Mediterranean waters, Tunisia) and investigate its toxicity. Molecular analyses confirmed the morphological identification of the isolated strain (APBZ12) as A. pseudogonyaulax. Moreover, it showed that it is 100% identical with strains of this species found in New Zealand, Japan, China and North Sea (Norway and Denmark) suggesting that this species is cosmopolitan. Until now, no toxin studies have been conducted on fully characterized (morphologically and molecularly) A. pseudogonyaulax....

The morpho-sedimentology of an artificial roadstead (Cherbourg, France)
Provedor de dados: 5
Autores: Gregoire, G.; Méar, Y.; Poizot, E.; Marion, C.; Murat, A.; Hebert, B.
Because of its size and geographical position, the Cherbourg roadstead appears as a favourable site for Marine Renewable Energy (MRE) industry. As a result, Cherbourg harbour has undergone profound changes (2015 and 2016) due to the installation of industrial infrastructures to service the needs of expanding MRE further offshore. However, little is known about the morpho-sedimentary distribution and associated dynamics of seabed sediments before and after harbour transformations. This study focuses on sedimentary dynamics using detailed morphological and sedimentological analyses based on data acquired before changes (2012). The main map includes a unique bathymetric map (1:35,000) and sedimentary maps showing the percentage of the characteristic grain...

Présence d'un Protogonyaulax sp. sur le littoral atlantique français pendant l'hiver 1987
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele.
A dinoflagellate belonging to Protogonyaulax genera and forming more than 20 cells chains was observed from November 1987 to February 1988 in Vilaine Bay and in the west ofIle d'Yeu (France). This species was not detected in coastal phytoplankton during preceding surveys. Close to Protogonyaulax affinis it seems to be a winter developing species for this coastal area. Vertical distribution shows in december a migration of the patch towards deeper layers. Increasing occurrences of species belonging to Protogonyaulax (Alexandrium Balech) genera inshore or coastal waters need to pay more attention to the taxonomy of such organisms. Some species are effectively well known as poisons producers.

Autores: Frere, L.; Paul-pont, I.; Moreau, Julien; Soudant, P.; Lambert, C.; Huvet, Arnaud; Rinnert, Emmanuel.
Every step of microplastic analysis (collection, extraction and characterization) is time-consuming, representing an obstacle to the implementation of large scale monitoring. This study proposes a semi-automated Raman micro-spectroscopy method coupled to static image analysis that allows the screening of a large quantity of microplastic in a time-effective way with minimal machine operator intervention. The method was validated using 103 particles collected at the sea surface spiked with 7 standard plastics: morphological and chemical characterization of particles was performed in &lt; 3 h. The method was then applied to a larger environmental sample (n = 962 particles). The identification rate was 75% and significantly decreased as a function of particle...

Autores: Cabezas, Patricia; Macpherson, Enrique; Machordom, Annie.
The family Galatheidae is among the most diverse families of anomuran decapod crustaceans, and the South-West Pacific is a biodiversity hot spot for these squat lobsters. Attempts to clarify the taxonomic and evolutionary relationships of the Galatheidae on the basis of morphological and molecular data have revealed the existence of several cryptic species, differentiated only by subtle morphological characters. Despite these efforts, however, relationships among genera are poorly understood, and the family is in need of a detailed systematic review.

Sanitation with sponge and plunger: western Atlantic slit-wormsnails (Mollusca : Caenogastropoda : Siliquariidae)
Provedor de dados: 5
Autores: Bieler, R.
Siliquariid Tenagodus (synonym: Siliquaria) snails are obligatory sponge commensals, with uncoiling and laterally slitted shells embedded inside Demospongiae hosts, and shell apertures facing the outside allowing for respiratory and gill-filter-feeding activities. Live-collected animals observed in situ within hosts provide the first detailed functional morphological study of the group, and form the basis for systematic revision of the western Atlantic members of type genus Tenagodus (Siliquariidae, synonym: Tenagodidae). Three species are recognized. Overall anatomical features of wide-ranging Atlantic T. modestus (Dall, 1881) and T. squamatus (de Blainville, 1827) [ = T. anguillae Morch, 18611 are similar to those previously described for New Zealand...

Morphology and environment of cold-water coral carbonate mounds on the NW European margin
Provedor de dados: 5
Autores: Wheeler, Andrew J.; Beyer, A; Freiwald, A; De Haas, H; Huvenne, V. A. I.; Kozachenko, M; Olu, Karine; Opderbecke, Jan.
Cold-water coral carbonate mounds, owing their presence mainly to the framework building coral Lophelia pertusa and the activity of associated organisms, are common along the European margin with their spatial distribution allowing them to be divided into a number of mound provinces. Variation in mound attributes are explored via a series of case studies on mound provinces that have been the most intensely investigated: Belgica, Hovland, Pelagia, Logachev and Norwegian Mounds. Morphological variation between mound provinces is discussed under the premise that mound morphology is an expression of the environmental conditions under which mounds are initiated and grow. Cold-water coral carbonate mounds can be divided into those exhibiting "inherited"...

Provedor de dados: 5
Autores: Saburova, Maria; Chomérat, Nicolas.
A new thecate, photosynthetic, sand‐dwelling marine dinoflagellate, Laciniporus arabicus gen. et sp. nov., is described from the subtidal sediments of the Omani coast in the Arabian Sea, northern Indian Ocean, based on detailed morphological and molecular data. Cells of L. arabicus are small (16.2‐30.1 μm long and 13.1‐23.2 μm wide), dorsoventrally compressed, with a small apical flap‐shaped projection pointing to the left. The thecal plate pattern is distinguished by minute first precingular plate and sulcus, which extends into the epitheca, with large anterior and right sulcal plates. The Kofoidian thecal tabulation is Po, X, 4′, 2a, 7′′, 6c, 6s, 5′′′, 2′′′′. Morphologically, the revealed plate pattern has an affinity to the Peridiniales, and LSU rDNA...

Small-scale morphological and genetic differentiation in the Mediterranean killifish Aphanius fasciatus (Cyprinodontidae) from a coastal brackish-water pond and an adjacent pool in northern Sardinia
Provedor de dados: 5
Autores: Maltagliati, F; Domenici, P; Fosch, Cf; Cossu, P; Casu, M; Castelli, A.
Two samples of Aphanius fasciatus collected in the Pilo pond (northern Sardinia, Italy) and in an adjacent pool of small surface area were analysed morphologically (235 individuals) and genetically (a subsample of 58 individuals). The aims of the present study were (i) to test the hypothesis that different predation pressures may be associated with morphological and/or genetic differences between samples from each habitat and (ii) to assess the level of divergence between the two populations. Morphological analysis was based on the relative size of fins because it has been shown to be associated with predation pressure. The relative caudal fin area (caudal fin area/total body surface) was smaller in specimens from the pool, in both males and females,...

Investigation of phytoplankton from East China Sea of the Pacific Ocean, offshore Réunion Island of the Indian Ocean, and the French Atlantic coast revealed a species of poorly known armored fusiform dinoflagellate. To clarify this species, morphology and phylogeny based on mitochondrial and nuclear protein gene sequence (Cox1, Cob and Hsp90) concatenated with the SSU, ITS region and LSU rDNA sequences were analysed. Epifluorescence and scanning electron microscopy observations revealed that the nucleus of the specimen was elongated, sausage-shaped and located equatorially on the left lateral side of the cell, and that the plate formula is Po, 3′, 1a, 6″, 6C, 8S, 5‴, 1p, 2′‴. These morphological features indicate that the species can be assigned to...

Provedor de dados: 5
Autores: Boudinar, A. S.; Chaoui, L.; Mahe, Kelig; Cachera, M.; Kara, M. H.
Somatic morphology and otolith shape were used to discriminate four samples of Atherina boyeri from three different habitats: Mellah lagoon (n = 269), Annaba Gulf (144 punctuated and 194 unpunctuated individuals) and Ziama inlet (n = 147) in eastern Algeria. For each individual, somatic morphology was described with 13 metrics and eight meristic measurements, while the otolith contour shape of 452 individuals from the three habitats was analysed using Fourier analysis. Then, two discriminant analyses, one using the 13 metric measurements and the other using Fourier descriptors, were used in order to discriminate populations of A. boyeri. The results of the discriminant analyses based on the two methods were similar, and showed that this species could be...

Autores: Barnabe, Gilbert.
Sampling of a population of D. Labrax was one with spear diving catches. Morphometric and meristic data were used to calculate a biometric index. This index showed that all the bass of the Sete area belong to Dicentrarchus labrax, even if they were black spotted on the upper part of the body. Morphology was slightly different according to sex, but sex determination was not always possible using morphometric data. This inshore population shows some morphological characteristics (branchiospine and lateral line scale number) different from the data collected on the same sp along the Maroc Atlantic coast by Gravier, 1961.

Implications of morphological and functional traits for trophic relationships within fish communities and marine trophic network architecture
Provedor de dados: 5
Autores: Cachera, Marie.
A current issue in ecology is to understand the contribution of biodiversity to ecosystem functioning and notably to comprehend how inter- and intra-specific trait variation affects trophic interactions between individuals and species, the trophic organization of communities and trophic network architecture. Particularly, morphology has historically been considered as a main determinant of organisms’ ecology, which led to the field of ecomorphology, and, from a functional perspective, is expected to influence trophic relationships and other ecological functions performed by species. This thesis aimed at studying the trophic organization of a marine fish community and its dependency on morphological and functional trait variation between and within species....

Two New Genera and Species of Ophiuroid (Echinodermata) from Hydrothermal Vents in the East Pacific
Provedor de dados: 5
Autores: Storh, Sabine; Segonzac, Michel.
Prior to this study, two species of ophiuroid had been described from hydrothermal vent sites, and another from methane cold seeps, all from the Atlantic Ocean. Although ophiuroids have occasionally been reported from vents in the Pacific Ocean as well, none has been described before. This study presents two new species, Spinophiura jolliveti gen. et sp. nov., family Ophiuridae, and Ophiolamina eprae gen. et sp. nov., family Ophiacanthidae, which are most likely endemic to reducing environments in the East Pacific. We also include detailed descriptions of the post-metamorphic development of these species. Spinophiura jolliveti is characterized by up to five rather long, semi-erect arm spines and a relatively small oral shield. Its postlarva is unusual in...

Provedor de dados: 5
Autores: Coute, Alain; Perrette, Catherine; Chomerat, Nicolas.
Clipperton Island is a small French coral atoll in the eastern Pacific Ocean, which has been rarely investigated because of its remote location and difficult access. There is little scientific information on this ecosystem and only a few microalgae have been reported from the lagoon. To date, only one dinoflagellate taxon, Peridiniopsis cristata, is known to inhabit the lagoon. During an expedition in 2005 to study the lagoon and the surrounding oceanic waters of Clipperton Island, a further investigation of the lagoon phytoplankton was undertaken. In addition to P. cristata, which was still abundant in the upper water layer, two other thecate dinoflagellates were recorded. One dinoflagellate was identified as Durinskia baltica, while the other had the...

The gills of Ichthyophis bannanicus have yet to be investigated. This paper describes the external morphological features of the gills of mature I. bannanicus embryos exhibiting three pairs of gills on their neck region. Each gill is composed of an axis and filaments. In newly released embryos, the filaments and the axis form at approximately 90° relative to each other; eventually, this angle decreases and the color of the gill fades. The filaments on the axis are arranged alternately, and their spacing varies. The mid-pair of gills is significantly longer by nearly twofold than the front and rear pairs. Likewise, the lengths of the front and rear pairs of gills are not significantly different (P &amp;gt;0.05); for the same pair of gills, the lengths of...

Protein restriction implies the functional involvement of several systems and organs, including the skeletal muscle, because it is a protein reservoir in the body. This study sought to analyze the morphological and morphometric features of the muscle fibers and neuromuscular junctions (NMJs) of the extensor digitorum longus (EDL) muscle in rats at 365 days of age, submitted to maternal protein restriction during the gestation and lactation periods. Wistar rats were divided into two groups: a Control Group - mothers fed a normal-protein diet (17 % protein) during pregnancy and lactation; and a Restricted Group - mothers fed a low-protein diet (6 % protein) during pregnancy and lactation. The pups were kept with the mother throughout the lactation period (21...

Provedor de dados: 77
Autores: Squarcia,Silvia Margarita; Sidorkewicj,Nora Silvia; Casanave,Emma Beatriz.
The morphology and morphometry of the cranial bones of Chaetophractus villosus were studied. The skull components are morphologically similar between adults of both sexes, and follow the generalized pattern for most of described dasypodids. The morphometric analysis, however, demonstrated that the bones lying in the rostrocaudal plane are mostly longest in females, determining higher values of the total, basal and condilobasal lengths of the skull, which are the main variables that contribute to a sexual dimorphism in this species

In humans, the right coronary artery is dominant. However, we did not find any citations in the literature concerning anatomical indicators of dominance among dogs. We used 30 hearts from mongrels of both sexes, fixed in 10% formalin. The branches of the coronary arteries were dissected with special attention to the levels that were considered to be reference points. In 96.7%, the circumflex branch of the left coronary artery reached or went beyond the crux cordis. The subsinuosus interventricular artery, ended before reaching the apex in 21 cases, at the apex in five cases and after the apex in four cases. The paraconal interventricular artery, ended before reaching the apex in two cases, at the apex in 11 cases and after the apex in 17 cases. The region...

Provedor de dados: 77
Autores: Codón,Stella Maris; Casanave,Emma Beatriz.
The morphological features of the oviduct in the armadillo Chaetophractus villosus (Desmarest, 1804) were studied. In the simple columnar epithelium, ciliated cells, secretory cells, and cells of the bottom of the folds are described. The most remarkable findings are the increase in number of ciliated cells, when present, from the fimbriae to the uterus, being the isthmus practically lined by ciliated cells, and that secretory cells are more abundant in the apical zone of the ampulla and fimbriae, than in the isthmus. Morphological changes along the year in the different portions are described.

In literature it is established that the iris musculature consists of striate muscle fibers in birds while in mammals it consists of smooth muscles. Some authors report the presence of smooth muscle tissue also in the iris of some species of birds. In the present study we report on the iris muscle tissues (type of tissue, direction and mean diameter of muscle fibers or cells) in five species of Accipitriformes (diurnal raptors) and four species of Strigiformes (nocturnal raptors) because they show different way of life depending of their predatory behavior. This morphological study was carried out from raptors died or euthanized at the Wild Life Rescue Centre of Sea and Water birds in Livorno (Italy). From histological examination of iris serial radial...

The aim of this study was to evaluate the stability and harmony of the morphostructural format of the Marin Magellan Meat Merino breed in order to contribute to knowledge about the differentiation of sheep populations. In summer 2010, evaluation on a sheep population coming from an incomplete absorbent crossbreeding of Corriedale by Australian Merino breeds was done in Magallanes Region, Chile. All three and five year-old ewes (62 and 50, respectively) were measured. Fourteen body measurements were taken and nine body indexes were calculated. Results show that the evaluated sheep population does not show significant intergenerational differences in most of the morphostructural variables. At the same time, there is a high between-age similarity in the...

Autores: Aversi-Ferreira,Tales Alexandre.
Rules, formulas and statistical tests have been widely used in studies that use continuous variables in the normal or Gaussian distribution or other tests whose data fit this type of distribution (t and z distributions) and whose parameters can be defined. However, there are cases in which the model and goal of the scientific work allow only the use of discrete or nominal variables. The absence or presence of a structure or organ (muscles, nerves, blood vessels, bones, and ligaments), characteristics associated with these organs, such as the source of nerves, vessels and muscles and the distribution of nerves and vessels are discrete and / or nominal variables that do not fit the Gaussian distribution, nor of z or t, unless the measures of these structures...

Cordelia's Dilemma, Historical Bias, and General Evolutionary Trends: Catfishes as a Case Study for General Discussions on Phylogeny and Macroevolution
Provedor de dados: 77
Autores: Diogo,Rui.
As noted Gould in his recent and last book «The structure of evolutionary theory», discourses on the high importance and frequency of evolutionary trends have consumed a great part of the research on the history of clades. Although aware that natural selection theoretically yields adaptation to immediate environments, many authors defend such trends as generalised improvements somehow conferring advantages across most or all experienced environments. The high importance given to evolutionary trends is questioned by Gould, who considers that such a high importance given to such evolutionary trends bears no necessary relationship to the relative frequency or casual weight of these events in evolution, but mainly to a major bias: trends tell histories, and...

Physical effort stimulates an increase in oxygen consumption in tissues, generating toxic chemical species derived from oxygen (ROS), which are considered the initiators of the lipid peroxidation process (LPO), the major mechanism of cellular injury. As the essential mechanism for maintaining the electrolyte balance depends on an effective kidney function, oxidative stress in this organ can be a key factor in the development and persistence of hypertension. This study aimed to determine the kidney changes induced by a combination of fluid restriction and exercise in rats. The study consisted of 24 male Wistar rats of 90 days of age, divided into four groups, two of which were submitted to water restriction and exercise on a treadmill.Twenty-four hours...

Autores: Schimming,Bruno Cesar.
The cervical salivary glands of the armadillo Dasypus novemcinctus was examined by light microscopy. These glands are situated on either side of the neck, divide in lobes and show a presence of a salivary bladder, associated with the main ducts of the gland. This gland is histologically a typical mixed glands, containing both mucous and serous elements, with mucous acini as the predominant secretory unit. The bladder itself is composed of a wall made up of pseudostratified epithelium, skeletal muscle and connective tissue. In general, the morphology of the cervical salivary glands appears similar to that described in other species of the mammals.

Provedor de dados: 77
Autores: Naidoo,N; Ishwarkumar,S; Lazarus,L; Pillay,P; Satyapal,K. S.
Recent studies have regarded the fibula flap as the benchmark for the reconstruction and treatment of compound wounds and lesions. Owing to its postero-lateral location within the leg, the application of the fibula flap is deemed aesthetically advantageous as the donor scar can be easily hidden. Since the fibula is anatomically characterized by a shaft and two extremities, this study aimed to investigate the nutrient foramen morphology and the relative fibular osteometry. Osteometric and morphological evaluation of 104 dry human fibulae, representing male and female individuals of the Black and Caucasian population groups that are native to South Africa, were conducted (Age range: 15 ­ 81 years old). The presence of single, double and six nutrient foramina...

Recently, the curriculum and the educational methodologies associated with health sciences courses are being reviewed and adapted. Pre-clinical sciences, such as anatomy and embryology are as well subjected to those changes. In human embryology courses it is common to use models to represent the different phases of development to facilitate learning, since the students can see and touch the models, obtaining knowledge by analogies. The purpose of the present study was to investigate if the construction of models by the students during practical embryology classes would improve or facilitate their learning. One year after the classes, 60 students answered a questionnaire with nine objective questions, including spaces for suggestions and observations. The...

Liver samples of Oreochromis niloticus cultivated in floating net cages were fixed for histological and ultrastructural studies with the objective of describing the hepatic parenchymal structure and the intrahepatic exocrine pancreatic tissue. Anatomically, the liver showed only two hepatic lobes. Histological analysis demonstrated that the hepatocytes were spread out as anastomotic cords, arranged in two cellular layers and surrounded by sinusoids. The intrahepatic exocrine pancreatic tissue exhibited an acinar arrangement and was diffused in the hepatic parenchyma. Structural analysis showed that the hepatocytes had a rounded nucleus and a rough endoplasmic reticulum with a parallel disposition to the nuclear membrane. The exocrine pancreatic cells...

Femoroacetabular impingement syndrome (FAI) is a clinical entity that has been recognized in recent years as a frequent cause of pain and the early development of hip arthrosis. Subspine hip impingement is characterized by the prominent or abnormal morphology of the anteroinferior iliac spine (AIIS), which contributes to the development of a clinical picture that is similar to FAI. The aims of this study were to propose a new morphological classification of the AIIS, to determine the prevalence of the different AIIS morphologies based on this classification and to correlate the presence of said morphologies with different gender and age groups. The sample consisted of 458 hemipelvises from individuals of known age and sex (264 men and 194 women). Each...

Autores: Fu,Jun; Qian,Zhihui; Ren,Luquan.
The morphology of filiform papilla root in the tongue of Chinese yellow cattle were studied by scanning electron microscopy, and several geometric models were established to analyze the possible effects of such structures on lingual mechanical functions. Conical and tongue-like filiform papillae were detected in different locations on the lingual surface, along with six types of root structures. A lingual groove surrounded the papillae in five of these structures. To date, such grooves have not been discussed in studies on bovine lingual morphology, and those distributed on the dorsal surface of the lingual apex can limit the motion ranges of filiform papillae. Two secondary papillae emerged from a groove on the dorsal surface of the lingual apex's caudal...

Among the present`s sesamoids in the human body, the fabella can be found in the posterior part of the knee in low incidence. This report is quite controverted in the classic anatomical literature as well as its constitution. Its fixation is on the tendon of the gastrocnemius lateralis, close to its origin, in the posterior part of condilus femuralis lateralis. However, when its occurs, generally induces in the knee the absence of arcuate ligament with the presence of fabellofibular ligament. The prevalence is larger in male individuals. Few studies discuss the histology of the fabella. Some authors suggest that the fabella basically formed by bone tissue and others describe it as a fibrocartilaginous.

The Rotator Cuff Footprint: A Cadaveric Study of the Morphometry and Morphology
Provedor de dados: 77
Autores: Naidoo,N; Lazarus,L; Satyapal,K. S.
The musculotendinous hood of the rotator cuff muscle complex is formed by four tendons which thicken and merge with the underlying glenohumeral capsule as they insert onto the respective regions of the humeral head. This insertional anatomy has been reported to exhibit several pathological patterns which serve as the basis for the operative repair of cuff tears. Since previous literature concentrated on macro-evaluations of tears specific to the supraspinatus tendon, the present study aimed to investigate the macro- morphological and morphometric parameters of all four rotator cuff tendons. Observation of the insertion site configurations and computation of the relative tendon morphometry were performed once the glenohumeral region in forty adult cadaveric...

Forensic Dentistry as a Morphological Exercise in the Medico-legal Investigation of Death
Provedor de dados: 77
Autores: Fonseca,Gabriel M; Cantín,Mario; Lucena,Joaquín.
In forensics, the nature of collected evidence makes analysis in many disciplines complex. Each type of trace evidence requires a unique systematic approach, and even though these approaches are significantly based on the size and morphology of the evidence being examined. In 1999, the Council of Europe Committee of Ministers adopted the Recommendation No. R (99)3 on the harmonization of medico-legal autopsies. This document promoted the adoption of internationally recognized and standardized protocols for forensic autopsies. Nevertheless, the interdisciplinary philosophy still needs integration of information from various investigative sources. An orientated and correct examination of the oral cavity requires specific knowledge of its anatomy and...

When a vein segment is grafted into arterial circulation, biomechanical forces stimulate modification of its structure. This morphological adaptive response is progressive during a medium or long term and occludes the vessel lumen, leading to a graft failure. The objective of this study was to characterize the early morphological response of the vascular wall in a terminal-terminal vascular vein graft model in Wistar rats. A segment of the femoral vein was placed in the femoral circulation. An end to end microsurgical graft anastomosis technique was implemented and standardized in twenty rats. The samples were processed with histological technique to analyze the overall structure with hematoxylin and eosin, the composition of the vessel wall with Masson...

Autores: Sayed-Ahmed,Ahmed; Elshafey,Anwer; Abd-Elmaksoud,Ahmed.
The camel (Camelus dromedarius) is an important multipurpose livestock species and its meat represents about 10% of the red meat consumption in Egypt. The reproductive efficiency of camel under natural condition is generally considered to be low. Sound knowledge about the tubular genital organs of this species might facilitate the application of new reproductive methodology. Our study was therefore conducted to investigate the morphology of mucosal surface of vagina and vestibule on camels using light, scanning and transmission electron microscopy. The mucosal surface of vagina consisted of stratified columnar epithelium with mucous secreting cells (goblet-like cells). SEM of vagina revealed the presence of longitudinal primary and secondary folds and...

Abstract  Background: The blunt-nosed viper Macrovipera lebetina (Linnaeus, 1758) is a medically important snake species in the Middle East. Its nominate subspecies Macrovipera l. lebetina is confined to Cyprus, where it is the only dangerously venomous snake species and heavily pursued. Despite the viper's large size, data on its body mass and sex-specific morphological differences are scarce. It is commonly believed that M. l. lebetina prefers freshwater proximity during summer. Hence, we aimed at investigating M. l. lebetina sex-specific morphological differences and its possible attraction to freshwater bodies in late summer.  Methods: Morphometric characteristics, proximity to water and conservation status of M. l. lebetina were investigated in Paphos...

Morphological characterization of the venom apparatus in the wolf spider Lycosa singoriensis (Laxmann, 1770)
Provedor de dados: 80
Autores: Yigit,N; Bayram,A; Danisman,T; Sancak,Z; Tel,MG.
The wolf spider Lycosa singoriensis (Laxmann, 1770) (Lycosidae: Araneae) is distributed throughout central and eastern Europe, including Russia, Kazakhistan and Turkey. This study describes the venom apparatus morphology of L. singoriensis through scanning electron microscopy (SEM). Its structure follows the general architecture observed in other spiders. Generally, a venom apparatus is composed by a pair of venom glands and chelicerae. L. singoriensis chelicerae are robust and consist of a stout basis and a movable apical segment (fang). The fang rests in a groove on the basal segment that is covered by different types of hair. L. singoriensis venom glands present equal size and measure about 4 mm in length. Each gland is enclosed by irregular muscular...

Evaluación de los caracteres diagnósticos de Oxymycterus josei Hoffmann, Lessa y Smith, 2002 (Rodentia: Cricetidae) con comentarios sobre la diferenciación de las especies uruguayas del género
Provedor de dados: 81
Autores: García-Olaso,Felipe.
Actualmente se reconocen dos especies del género Oxymycterus en Uruguay: O. nasutus y O. josei. Estas especies parecen ser un caso particular dentro del género, ya que son simpátridas, genéticamente diferenciadas pero morfológicamente muy similares. Principalmente, dos caracteres diagnósticos fueron descritos para distinguirlas. Este trabajo evalúa la consistencia de esos dos caracteres craneodentarios para diferenciar las especies. Los resultados descartan los pliegues dentarios, pero corroboran al ancho de placa zigomática, como caracteres diagnósticos de O. josei. El actual conocimiento genético, morfológico y geográfico del género en la región sugiere que hay interrogantes históricas que permanecen por ser resueltas.

A distinctive new cloud-forest rodent (Hystricognathi: Echimyidae) from the Manu Biosphere Reserve, Peru
Provedor de dados: 81
Autores: Patterson,Bruce D.; Velazco,Paul M.
Recent surveys in Peru 's Manu National Park and Biosphere Reserve uncovered a new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabiting Andean cloud-forests at 1900 m, the new rodent belongs to a radiation of "brush-tailed tree rats" previously known only from the Amazon, Orinoco, and other lowland river drainages. Phylogenetic analysis of morphology (cranial and dental characters) unambiguously allies the new species with species of Isothrix. While the inclusion of the new taxon does not resolve the "star phylogeny" which underlies the echimyid radiation, it identifies the Andes as a possible theatre for the evolution of some soft-haired members of the group. The new species is described and a revised diagnosis of the...

Antennule development during copepodite phase of some representatives of Harpacticoida (Copepoda, Crustacea)
Provedor de dados: 16
Autores: Dahms, Hans-Uwe.
The copepodite antennule development of representatives of 6 harpacticoid families is studied and discussed in detail and that of 8 genera of harpacticoids from 7 families is schematically illustrated. Twenty-seven genera out of 17 harpacticoid families are compared on the basis of own investigations and data from the literature. The origin of newly formed segments can be determined by seta numbers of segments, relative segment length, furrows indicating previous articulations and by the position of the segment which bears the proximal aesthetasc. There are 2 zones of segment formation, both located in the middle part of the first antenna. Normal segment formation takes place distally from the second, aesthetasc-bearing segment from C I to C II and...

Systematics of Ariantinae (Gastropoda, Pulmonata, Helicidae), a new approach to an old problem
Provedor de dados: 16
Autores: Groenenberg, D.S.J.; Subai, P.; Gittenberger, E.
A new starting-point in Ariantinae systematics is presented by combining data on traditional shell morphology and genital anatomy, with phylogeny reconstructions based on DNA sequence data. For nearly all genera and subgenera one or more shells are depicted and drawings of the proximal part of the genital organs are shown to illustrate the morphological diversification within the subfamily. For as much as our material allowed it, partial sequences are presented for Histone H3 (H3), Cytochrome c oxidase subunit I (COI), Cytochrome B (CytB) and 16S ribosomal RNA (16S). Some of the allegedly speciose genera like Chilostoma and Campylaea (Zilch, 1960) do not represent monophyletic groups of species, whereas most of the remaining nominal taxa (e.g. Causa,...

Morphological re-evaluation of the parotoid glands of Bufo ictericus (Amphibia, Anura, Bufonidae)
Provedor de dados: 16
Autores: Almeida, P.G. de; Felsemburgh, F.A.; Azevedo, R.A.; Brito-Gitirana, L. de.
Multicellular glands in the amphibian integument represent a signifi  cant evolutionary advance over those of fi shes. Bufonids have parotoid glands, symmetrically disposed in a post-orbital position.  Their secretion may contribute to protection against predators  and parasites. This study provides a re-evaluation of the morphology  of the Bufo ictericus parotoid glands. The parotoid gland  integument of the medial surface shows rounded depressions  with small pores that connect with the duct openings of the larger  granular glands. Under light microscopic evaluation the integument  is constituted by typical epidermis, supported by dermis  subdivided into a spongious dermis, a reticular dermis, and a  compact dermis. The Eberth-Katschenko layer is...

Systematics and phylogeny of Sitana (Reptilia: Agamidae) of Peninsular India, with the description of one new genus and five new species
Provedor de dados: 16
Autores: Deepak, V.; Giri, V.B.; Asif, M.; Dutta, S.K.; Vyas, R.; Zambre, A.M.; Bhosale, H.; Karanth, K.P.
We revise the taxonomy of the agamid genus Sitana Cuvier, 1829, a widely distributed terrestrial lizard from the Indian subcontinent based on detailed comparative analyses of external morphology, osteology and molecular data. We sampled 81 locations spread over 160,000 km2 in Peninsular India including type localities, which represented two known and five previously undescribed species. Based on general similarity in body shape and dewlap all species were hitherto identified as members of the genus Sitana. However, Sitana deccanensis and two other morphotypes, which are endemic to north Karnataka and Maharashtra in Peninsular India, are very distinct from the rest of the known members of the genus Sitana based on their external morphology and osteology....

Morphological comparison of Mesocyclops araucanus Campos et al., 1974, and M. longisetus Thiébaud, 1912, and first description of their males
Provedor de dados: 16
Autores: Pilati, Alberto; Menu-Marque, Silvina.
Originally described by Löffler in 1962 as a variety of Mesocyclops longisetus, M. araucanus was found to have autapomorphies of its own to deserve specific rank. For a long time the identification of these two species were mixed up. Here, M. araucanus female is redescribed and the male described for the first time. A comparison is made with M. longisetus, whose male is also described for the first time. Detailed comparison between these two species shows that the following traits on specimens of both sexes can be used to separate the species: length/width ratio of caudal rami, ratio of terminal caudal setae, and length/width ratio of last segment of endopod of leg 4. Additional diagnostic characters for each sex are given. The geographic distributions of...

A multi-gene phylogeny of Lactifluus (Basidiomycota, Russulales) translated into a new infrageneric classification of the genus
Provedor de dados: 16

Infrageneric relations of the genetically diverse milkcap genus Lactifluus (Russulales, Basidiomycota) are poorly known. Currently used classification systems still largely reflect the traditional, mainly morphological, characters used for infrageneric delimitations of milkcaps. Increased sampling, combined with small-scale molecular studies, show that this genus is underexplored and in need of revision. For this study, we assembled an extensive dataset of the genus Lactifluus, comprising 80 % of all known species and 30 % of the type collections. To unravel the infrageneric relationships within this genus, we combined a multi-gene molecular phylogeny, based on nuclear ITS, LSU, RPB2 and RPB1, with a morphological study, focussing on five important...

Phylogeny of the subfamilies of the family Braconidae (Hymenoptera: Ichneumonoidea)
Provedor de dados: 16
Autores: Quicke, D.L.J.; Achterberg, C. van.
A phylogenetic analysis of the subfamilies of the family Braconidae Nees, 1812 is presented. The analysis employing 96 phylogenetically informative characters was performed using the computerized parsimony programmes PAUP and Hennig86. The cladograms obtained show that the Braconidae can be divided into three major groups of subfamilies. These are a lineage comprising the mainly ectoparasitic cyclostomes and relatives, and two advanced endoparasitic groups, both apparently derived from somewhere near the endoparasitic cyclostome subfamily Rogadinae Foerster, 1862 sensu stricto. As a result of the phylogenetic analysis subfamily rank is given to the Exothecinae Foerster, 1862 (including the Hormiini Foerster, 1862), the Rhyssalinae Foerster, 1862 (including...

The Colletotrichum gigasporum species complex
Provedor de dados: 16
Autores: Liu, F.; Cai, L.; Crous, P.W.; Damm, U.
In a preliminary analysis, 21 Colletotrichum strains with large conidia preserved in the CBS culture collection clustered with a recently described species, C. gigasporum, forming a clade distinct from other currently known Colletotrichum species complexes. Multi-locus phylogenetic analyses (ITS, ACT, TUB2, CHS-1, GAPDH) as well as each of the single-locus analyses resolved seven distinct species, one of them being C. gigasporum. Colletotrichum gigasporum and its close allies thus constitute a previously unknown species complex with shared morphological features. Five of the seven species accepted in the C. gigasporum species complex are described here as novel species, namely C. arxii, C. magnisporum, C. pseudomajus, C. radicis and C. vietnamense. A...

Phylogenetic reconstruction prompts taxonomic changes in Sauropus, Synostemon and Breynia (Phyllanthaceae tribe Phyllantheae)
Provedor de dados: 16
Autores: Welzen, P.C. van; Pruesapan, K.; Telford, I.R.H.; Esser, H.-J.; Bruhl, J.J.
Previous molecular phylogenetic studies indicated expansion of Breynia with inclusion of Sauropus s.str. (excluding Synostemon). The present study adds qualitative and quantitative morphological characters to molecular data to find more resolution and/or higher support for the subgroups within Breynia s.lat. However, the results show that combined molecular and morphological characters provide limited synergy. Morphology confirms and makes the infrageneric groups recognisable within Breynia s.lat. The status of the Sauropus androgynus complex is discussed. Nomenclatural changes of Sauropus species to Breynia are formalised. The genus Synostemon is reinstated.

Trichoderma (Hypocrea) species with green ascospores from China
Provedor de dados: 16
Autores: Zhu, Z.X.; Zhuang, W.Y.
Stromata of Trichoderma species having green ascospores were collected in various regions of China. Based on morphology of the sexual and asexual morph, culture characteristics, and sequence analyses of rpb2 and tef1 genes, 17 species with green ascospores were identified. Among them, Trichoderma rosulatum, T. rufobrunneum and T. stipitatum are described as new species, and seven other species are reported for the first time from China. Trichoderma rosulatum produces small bright yellow or pale greenish stromata with dense dark green ostioles and gliocladium-like conidiophores, shows a close relationship to T. thelephoricola, and belongs to the Chlorospora clade. Trichoderma rufobrunneum, which typically forms reddish brown stromata, is recognised as a...

Tales of the unexpected: angiocarpous representatives of the Russulaceae in tropical South East Asia
Provedor de dados: 16
Autores: Verbeken, A.; Stubbe, D.; Putte, K. van de; Eberhardt, U.; Nuytinck, J.
Six new sequestrate Lactarius species are described from tropical forests in South East Asia. Extensive macro- and microscopical descriptions and illustrations of the main anatomical features are provided. Similarities with other sequestrate Russulales and their phylogenetic relationships are discussed. The placement of the species within Lactarius and its subgenera is confirmed by a molecular phylogeny based on ITS, LSU and rpb2 markers. A species key of the new taxa, including five other known angiocarpous species from South East Asia reported to exude milk, is given. The diversity of angiocarpous fungi in tropical areas is considered underestimated and driving evolutionary forces towards gasteromycetization are probably more diverse than generally...

Materials for a more stable subdivision of the genus Uca Leach
Provedor de dados: 16
Autores: Beinlich, B.; Hagen, H.O. von.
The debate on a proper subdivision of the large genus Uca was initiated by the conflicting proposals of Bott (1973) and Crane (1975). In spite of recent computer-aided mending attempts, the overall situation (instability of Uca systematics and nomenclature) has not convincingly improved. Here we try to settle the debate by presenting a simple cladistic analysis sensu Hennig (1950) based on selected morphological characters supplemented by functional remarks and a few behavioural data resulting from fieldwork. All 94 species (except six) were examined, mostly by using the authors’ collection of Uca (partly in Marburg and partly deposited in the Leiden Museum) and all species (see list in chapter 5) are assigned to one of the eight subgenera recognized:...

Autores: Zhang, Z.F.; Liu, F.; Zhou,, X.; Liu, X.Z.; Liu, S.J.; Cai, L.
Karst caves are distinctly characterised by darkness, low to moderate temperatures, high humidity, and scarcity of organic matter. During the years of 2014–2015, we explored the mycobiota in two unnamed Karst caves in Guizhou province, China, and obtained 563 fungal strains via the dilution plate method. Preliminary ITS analyses of these strains suggested that they belonged to 246 species in 116 genera, while 23.5 % were not identified to species level. Among these species, 85.8 % (211 species) belonged to Ascomycota; 7.3 % (18 species) belonged to Basidiomycota; 6.9 % (17 species) belonged to  Mucoromycotina. The majority of these species have been previously known from other environments, mostly from plants or animals as pathogens, endophytes or via a...

The manifold characters of orbicules: structural diversity, systematic significance, and vectors for allergens
Provedor de dados: 16
Autores: Vinckier, S.; Cadot, P.; Smets, E.
In the anthers of flowering plants, gymnosperms, and seed ferns, tiny (¡1 mm) granules might occur on the radial and innermost tangential wall of secretory tapetum cells. These sporopollenin granules develop simultaneously with the pollen exine and are called orbicules or Ubisch bodies. The present paper focuses on two quite different topics associated with orbicules. The morphological and ultrastructural diversity of orbicules in the order Gentianales is summarized, and it is demonstrated that orbicules are a plesiomorphic feature in the order. Furthermore, orbicule characters seemed to be correlated with evolutionary trends in pollen dispersal unit and tapetum type features. In the second part, we report on our investigation of Corylus avellana L....

Something gone awry: unsolved mysteries in the evolution of asymmetric animal genitalia
Provedor de dados: 16
Autores: Schilthuizen, M.
The great diversity in genital shape and function across and within the animal phyla hamper the identification of specific evolutionary trends that stretch beyond the limits of the group under study. Asymmetry might be a trait in genital morphology that could play a unifying role in the evolutionary biology of genitalia. Here, I review the current knowledge on the taxonomic distribution, phylogenetic patterns, genetics, development, and ecology of asymmetric (chiral) genitalia. Asymmetric genitalia (male as well as female) have evolved from bilaterally symmetric ones (and sometimes vice versa), innumerous times in most animal taxa with internal fertilisation, and especially in Platyhelminthes, Arthropoda, Nematoda, and Chordata. In groups with asymmetric...

Radix labiata is a widely distributed Palaearctic freshwater snail. This work aims to improve the knowledge of the intraspecific variability in the most important characters used for its determination. To find out which characters are really suitable to distinguish this species from other similar Radix species an integrative approach was applied, involving morphological and molecular data.Molecular sequences of the nuclear spacer fragment ITS-2 and/or the mitochondrial gene fragment cyt-b were obtained from 26 individuals of R. labiata from different regions of Europe, including type localities of Limnaeus pereger labiatus. From the subsample of 24 specimens of which sequences of both gene fragments were available, the variability of several characters...

Genetic and morphological variation in corallivorous snails (Coralliophila spp.) living on different host corals at Curaçao, southern Caribbean
Provedor de dados: 16
Autores: Potkamp, G.; Vermeij, M.J.A.; Hoeksema, B.W.
Snails of the genus Coralliophila (Muricidae: Coralliophilinae) are common corallivores in the Caribbean, feeding on a wide range of host species. In the present study, the morphological and genetic variation in C. galea and C. caribaea were studied in relation to their association with host coral species at Curaçao. Differences in shell shape among snails living on different hosts were quantified using geometric morphometric and phylogenetic relationships were studied using two mitochondrial markers (12S and COI). Based on these analyses, a new species, C. curacaoensis sp. nov., was found in association with the scleractinian coral Madracis auretenra. Both C. galea and C. caribaea showed host-specific differences in shell shape, size, and shell allometry...

Provedor de dados: 16
Autores: Kolbasov, Gregory A.; Høeg, Jens T.; Elfimov, Alexei S.
Scanning electron microscopy was used to provide a full morphological description of cypris morphology in the acrothoracican species Lithoglyptes milis and L. habei (Lithoglyptidae). Special attention was given to lattice organs, antennules, thorax, thoracopods, abdomen, and furcal rami. Cypris larvae of the Acrothoracica share some putative plesiomorphic features with the cypris-like ascothoracid larvae of the non-cirripede taxon Ascothoracida. The most notable are traces of abdominal segmentation and carapace lattice organs without pore fields. Acrothoracican cyprids also share numerous synapomorphies with those of the Thoracica and the Rhizocephala. This list includes a four-segmented antennule with a triangular first segment of two sclerites set at an...

Morphological and molecular data to describe a hybrid population of the Common toad (Bufo bufo) and the Spined toad (Bufo spinosus) in western France
Provedor de dados: 16
Autores: Trujillo, T.; Gutiérrez-Rodríguez, J.; Arntzen, J.W.; Martínez-Solano, I.
The use of hyper-variable markers across species is often hindered by low cross-species amplification success, a reduced level of polymorphism or a high frequency of null alleles. However, optimizing sets of reliable and informative markers that can be consistently amplified and scored across taxa is key to address questions about patterns of genetic diversity and structure, hybridization and speciation. Here we present 14 newly developed microsatellite markers in the Spined toad (Bufo spinosus), assess their polymorphism in two Iberian populations and test for cross-species amplification in the closely related Common toad (Bufo bufo). We then use the 12 loci co-amplifying in both species to the study of a morphologically intermediate population (Moyaux)...

Provedor de dados: 16
Autores: Zamora, J.C.; Calonge, F.D.; Martín, M.P.
A revision of the classification of Geastrum sect. Geastrum is presented on the basis of an integrative taxonomic approach, which involves the study of morphological, molecular, ecological, and chorological data. Four DNA regions are analysed: the ITS and LSU nrDNA, rpb1, and atp6. Phylogenetic reconstructions include 95 ingroup samples and show five main clades, which are considered as five subsections, one of them proposed as new (G. subsect. Hungarica), and a total of 27 lineages recognizable at species level. Discriminant function analyses, ANOVAs and Tukey’s HSD tests on more than 500 basidiomata reveal the utility of several quantitative morphological characters for species delimitation. As a result of the combination of the different sources of...

In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented. In the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella.

Usefulness of morphological characters for infrageneric classiﬁcation of Elatostema (Urticaceae)
Provedor de dados: 16
Autores: Hadiah, J.T.; Conn, B.J.
In 1896, Hans Hallier was the first author to reduce the two genera Pellionia and Procris to subgeneric status within the genus Elatostema (Urticaceae). In 1935 and 1936, Hilde Schröter and Hubert Winkler proposed the following four subgenera: subg. Elatostema, subg. Elatostematoides, subg. Pellionia and subg. Weddellia, while maintaining Procris as a distinct genus. More recently, Wang (1980a) rejected Schröter and Winkler’s subgeneric classification of Elatostema and proposed a sectional and serial infrageneric classification of recognising as sections Androsyce, Elatostema, Laevisperma, Pellionioides and Weddellia (as ‘Weddelia’). He maintained both Pellionia and Procris as distinct genera. All previous researchers of Elatostema and related taxa...

Doto uva Marcus, 1955 is a nudibranch species recorded from the Brazilian and Chilean coast. In spite of its wide distribution, D. uva has been described only superficially, mainly as to the pattern of its coloration, external morphology, radular teeth and reproductive system. Here we substantially extend this description, paying special attention to the morphology, anatomy and histology of the digestive and reproductive system. Furthermore, new data on the morphology of the central nervous system and its cell types are given, and finally, the egg mass is described. On the basis of these data, we consider the Doto specimens described from Chile conspecific with those from Brazil.

A black, non-troglomorphic amphibian from the karst of Slovenia: Proteus anguinus parkelj n. ssp. (Urodela: Proteidae)
Provedor de dados: 16
Autores: Sket, B.; Arntzen, J.W.
A morphologically distinct cavernicolous salamander Proteus anguinus from southeastern Slovenia (Bela Krajina) is described as P. a. parkelj ssp. n. It differs from P. a. anguinus in a dark pigmentation, fully developed eyes, a skull with broader and shorter bones and fewer teeth, a voluminous jaw musculature that gives the head a bulky appearance, a proportionally longer trunk with a higher number of vertebrae, shorter extremities, and a shorter tail. Most of these traits are considered to be plesiomorphic character states. An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Stična (DNei = 0.23). Both populations in turn are genetically dissimilar to a...

South Pacific Cleistocalyx transferred to Syzygium (Myrtaceae)
Provedor de dados: 16
Autores: Biffin, E.; Craven, L.A.; Tuiwawa, M.; Crisp, M.D.; Gadek, P.A.
Evidence from both morphological and molecular phylogenetic data support the view that the circumscissile calycine calyptra, the sole defining character of Cleistocalyx, has multiple origins within Syzygium s. l. and is therefore an invalid basis for generic circumscription. Accordingly, the Fijian Cleistocalyx are transferred to Syzygium, and the new combinations Syzygium decussatus, S. eugenioides and S. seemannii, are made. Syzygium myrtoides is reinstated, and Cleistocalyx ellipticus, C. longiflorus, C. kasiensis and C. seemannii var. punctatus are reduced to the synonymy of S. seemannii. The distribution of S. seemannii is extended to Vanuatu.

Short notes and reviews Bidder’s organ in the female of Bufo ictericus: morphological characterization
Provedor de dados: 16
Autores: Farias, C.F.; Brito-Gitirana, L. de; Carvalho-e-Silva, S.P.
Bidder’s organ has been cited as a structure present only in males of the toad family Bufonidae, and is used as a systematic characteristic. In this study, we examined females of Bufo ictericus in order to ascertain whether this structure also occurs in females. Macroscopic observations and light microscopy technique for paraffin embedding were performed. This study reveals that females of Bufo ictericus can have a Bidder’s organ with typical morphology, and in close spatial relationship with the ovary. This suggests that the Bidder’s organ is not an exclusive structure for male toads, but that it may also occur in active females.

Molecular and phenotypic characterisation of novel Phaeoacremonium species isolated from esca diseased grapevines
Provedor de dados: 16
Autores: Essakhi, S.; Mugnai, L.; Crous, P.W.; Groenewald, J.Z.; Surico, G.
Petri disease and esca are very destructive grapevine decline diseases that occur in most countries where grapevine (Vitis vinifera) is cultivated. Phaeoacremonium species are among the principal hyphomycetes associated with symptoms of the two diseases, producing a range of enzymes and phytotoxic metabolites. The present study compared the phylogeny of a global collection of 118 Phaeoacremonium isolates from grapevines, in order to gain a better understanding of their involvement in Petri disease and esca. Phylogenetic analyses of combined DNA sequence datasets of actin and β-tubulin genes revealed the presence of 13 species of Phaeoacremonium solated from esca diseased grapevines. Phaeoacremonium aleophilum was the most frequently isolated species with...

Immature stages and phylogenetic importance of Astrapaeus, a rove beetle genus of puzzling systematic position (Coleoptera, Staphylinidae, Staphylinini)
Provedor de dados: 16
Autores: Pietrykowska-Tudruj, E.; Staniec, B.; Wojas, T.; Alexey, A.
For the first time eggs, larvae and pupae obtained by rearing are described for Astrapaeus, a monotypic West Palearctic rove beetle genus of a puzzling phylogenetic position within the megadiverse tribe Staphylinini. Morphology of the immature stages of Astrapaeus ulmi is compared to that of other members of the tribe and discussed in a phylogenetic context. Contrary to conventional systematics and in accordance with recently developed phylogenetic hypotheses based on morphology of adults, larval morphology supports the non-Quediina affiliation of Astrapaeus. Eggs and pupae provided fewer characters with putative phylogenetic signal. Under laboratory conditions, a peculiar preference for isopod prey was observed for A. ulmi. However, this could not be...

Polyphasic characterisation of three new Phyllosticta spp
Provedor de dados: 16
Autores: Su, Y.Y.; Cai, L.
Three new species of Phyllosticta, P. hostae on Hosta plantaginea (China), P. schimae on Schima superba (China), and P. ilicis-aquifolii on Ilex aquifolium (UK), are described and illustrated in this study. They are compared with morphologically similar and phylogenetically closely related species. A polyphasic approach using phylogeny, host association, disease symptoms, colony and morphological characteristics, is employed to justify the introduction of the new taxa. Phylogenetic relationships of the new species with other Phyllosticta species are revealed by DNA sequence analyses based on the nrDNA-internal transcribed spacer (ITS) regions and a combined multilocus alignment of the ITS, partial translation elongation factor 1-alpha (TEF1), actin (ACT),...

Phylogenetic and phytogeographical relationships in Maloideae (Rosaceae) based on morphological and anatomical characters
Provedor de dados: 16
Autores: Aldasoro, J.J.; Aedo, C.; Navarro, C.
Phylogenetic relationships among 24 genera of Rosaceae subfam. Maloideae and Spiraeoideae are explored by means of a cladistic analysis; 16 morphological and anatomical characters were included in the analysis. Published suprageneric classifications and characters used in these classifications are briefly reviewed. Additionally, some new features are here reported, such as seed shape, presence or absence of endosperm, and number of cell layers in the seed coat and in the endosperm. Parsimony analyses indicate that Eriobotrya and Rhaphiolepis form a well-supported clade that is the sister to the remainder of the subfamily. This result is in agreement with published ITS sequence data. Other clades are not supported, with the exception of the group...

Morphology and DNA sequence data reveal the presence of Globodera ellingtonae in the Andean region
Provedor de dados: 16
Autores: Lax, P.; Rondan Dueñas, J.C.; Franco-Ponce, J.; Gardenal, C.N.; Doucet, M.E.
Potato cyst nematodes, G. rostochiensis and G. pallida, are the most economically important nematode pests of potatoes worldwide and are subject to strict quarantine regulations in many countries. Globodera ellingtonae was recently described from Oregon (USA), with its host-plant in the field being still unknown. Roots of Andean potatoes from the North of Argentina have been found attacked by this nematode, providing further evidence that this is a potato cyst nematode species, along with G. pallida and G. rostochiensis. New information about morphological, biological and molecular aspects of G. ellingtonae is provided for diagnostic purposes. The Argentine population showed morphological differences from specimens from Oregon; therefore, new diagnostic...

Fossil evidence of the zygomycetous fungi
Provedor de dados: 16
Autores: Krings, M.; Taylor, T.N.; Dotzler, N.
Molecular clock data indicate that the first zygomycetous fungi occurred on Earth during the Precambrian, however, fossil evidence of these organisms has been slow to accumulate. In this paper, the fossil record of the zygomycetous fungi is compiled, with a focus on structurally preserved Carboniferous and Triassic fossils interpreted as zygosporangium-gametangia complexes and resembling those of modern Endogonales. Enigmatic microfossils from the Precambrian to Cenozoic that have variously been interpreted as, or compared to, zygomycetous fungi are also discussed. Among these, the spherical structures collectively termed ‘sporocarps’ are especially interesting because of their complex investments and abundance in certain Carboniferous and Triassic rocks....

A reevaluation of the evidence supporting an unorthodox hypothesis on the origin of extant amphibians
Provedor de dados: 16
Autores: Marjanovic, D.; Laurin, M.
The origin of frogs, salamanders and caecilians is controversial. McGowan published an original hypothesis on lissamphibian origins in 2002 (McGowan, 2002, Zoological Journal of the Linnean Society, 135: 1-32), stating that Gymnophiona was nested inside the 'microsaurian' lepospondyls, this clade was the sister-group of a caudate-salientian-albanerpetontid clade, and both were nested inside the dissorophoid temnospondyls. We have investigated McGowan's data matrix and isagree with the scoring of 35% of the cells. All taxa and all but two characters are affected. In some cases, we have a different interpretation about correspondence between morphology and character states, or we delimit states differently (or use information that was unknown in 2002). In...

Gattya wimleni spec. nov. (Cnidaria: Hydrozoa), a new hydroid from Madagascar, and an identification key to the Gattya species
Provedor de dados: 16
Autores: Gravier-Bonnet, N.
Gattya wimleni spec. nov. is referred to the family Halopterididae (Hydroida, Thecatae). Colonies were collected at Tuléar (SW Madagascar, Indian Ocean) on the deeper part of the lower sloping platform, at 35 to 45 metres depth on the outer slope of the great barrier reef. The specimens were studied in transmitted light and by SEM. They differed from the eight species of Gattya already known in having a hydrothecal margin provided with four large rounded teeth of equal size - one abcauline, one adcauline and two lateral, curving inwards over the aperture, the laterals being hidden behind the lateral nematothecae in profile view. Its closest affinities are with the species G. multithecata (Jarvis, 1922) and G. aglaopheniaformis (Mulder &amp; Trebilcock,...

Morphological plasticity in Cladosporium sphaerospermum
Provedor de dados: 16
Autores: Dugan, F.M.; Braun, U.; Groenewald, J.Z.; Crous, P.W.
A morphologically distinct isolate of Cladosporium sphaerospermum from a North American patent collection, referenced as Cladosporium lignicola in the patent, was examined. Generic affinity was confirmed by scanning electron microscopic examination of conidiogenous loci and conidial hila. Species identity as C. sphaerospermum was indicated by DNA sequence data derived from actin and translation elongation factor 1-α genes, and the internal transcribed spacer region. The isolate broadens the morphological limits of C. sphaerospermum by production of obclavate, occasionally transversely septate conidia with subrostrate conidiogenous apices (‘alternarioid’ conidia), and by production of conidia larger than those in prior standard descriptions. Type material...

Entoloma subgenus Leptonia in boreal-temperate Eurasia: towards a phylogenetic species concept
Provedor de dados: 16
Autores: Morozova, O.V.; Noordeloos, M.E.; Vila, J.
This study reveals the concordance, or lack thereof, between morphological and phylogenetic species concepts within Entoloma subg. Leptonia in boreal-temperate Eurasia, combining a critical morphological examination with a multigene phylogeny based on nrITS, nrLSU and mtSSU sequences. A total of 16 taxa was investigated. Emended concepts of subg. Leptonia and sect. Leptonia as well as the new sect. Dichroi are presented. Two species (Entoloma percoelestinum and E. sublaevisporum) and one variety (E. tjallingiorum var. laricinum) are described as new to science. On the basis of the morphological and phylogenetical evidence E. alnetorum is reduced to a variety of E. tjallingiorum, and E. venustum is considered a variety of E. callichroum. Accordingly, the...

Genetic differentiation in Gammarus fossarum and G. caparti (Crustacea, Amphipoda) with reference to G. pulex pulex in northwestern Europe
Provedor de dados: 16
Autores: Scheepmaker, Maarten; Dalfsen, Jan van.
Genetic differentiation among G. fossarum Koch, 1835 from different stations in Germany, Switzerland, Belgium and northern France, and the closely related Belgian form G. caparti Pètre-Stroobants, 1980 was investigated by electrophoresis at 20 enzyme loci. Although morphologically variable, geographically distant populations of G. cf. fossarum were hitherto considered conspecific. In the present study, populations of G. cf. fossarum and G. caparti were examined with reference to G. pulex pulex as an estimate for genetic differentiation at the species level. With G. p. pulex as a standard, genetic differentiation among geographically distant populations of G. cf. fossarum is occasionally observed at species level. The populations of G. caparti studied were...

Geographic variation and taxonomy of crested newts (Triturus cristatus superspecies): morphological and mitochondrial DNA data
Provedor de dados: 16
Autores: Arntzen, J.W.; Wallis, Graham P.
Within the newt genus Triturus, the large-bodied species in the T. cristatus (crested newt) superspecies show an unusual degree of variation in relative trunk length as a result of among-taxon variation in interlimb vertebral count. Here we examine the systematic value of this feature as assessed by both exterior measurement (Wolterstorff Index) and direct radiographic count of rib-bearing vertebrae, with particular reference to a number of confounding factors (sex differences, hybridisation, geographic variation, allometry, preservation effects). Using our mtDNA haplotype data, which are largely concordant with geographic distribution of species, we find that direct count of the rib-bearing vertebrae performs more reliably (14% misclassification) than...

Morphological evolution of some migratory Ficedula flycatchers
Provedor de dados: 16
Autores: Outlaw, D.C.
Long-distance migration imposes physiological and morphological selection pressures on birds. The genus Ficedula, a lineage of Old World flycatchers, consists of long- and short-distance migratory species, as well as sedentary species. Members of each of these groups are not reciprocally monophyletic, yet each of the behavioral groups is morphologically distinguishable even when accounting for phylogeny. Long-distance migratory species have more pointed wings than either short-distance migratory or sedentary species, and migratory behaviors and wing pointed-ness are phylogenetically correlated. This suggests that migratory Ficedula species have converged on a migratory phenotype, and that migration may be a selective agent that has shaped the...

Taxonomic utility of female copulation organs in Sericini chafers (Coleoptera, Scarabaeidae), with special reference to asymmetry
Provedor de dados: 16
Autores: Özgül-Siemund, A.; Ahrens, D.
Female genitalia are widely underrepresented in taxonomic studies. Here we investigate the morphological variation among female copulation organs for a group of scarab beetles (Sericini) with similar ecology, external morphology and copulation mechanics. We examined traits qualitatively and quantitatively based on 80 and 18 species (genus Pleophylla), respectively. Additionally we explored whether female genitalia are affected by asymmetry. The vast diversity of slerotised structures including their shapes illustrated the high taxonomic and phylogenetic utility of female genitalia in this group. The morphometric analysis of Pleophylla, confirmed that sclerotisations in the ductus bursae are very suitable for species-level taxonomic purposes. Stable...

Autores: Davies, A.M.R.; Maxted, N.; Maesen, L.J.G. van der.
A comprehensive morphological survey and analysis of all taxonomically recognised wild species of Cicer L. (Leguminosae, Cicereae) is presented. The data (104 characters from 152 herbarium specimens representing 34 of the 44 recognised taxa in the genus Cicer with supplementary data for the remaining taxa taken from the literature) were analysed using multivariate statistics (cluster analysis, factor analysis and ordination techniques). The results are discussed in the context of extant classifications and the re-organisation of a novel infrageneric classification also incorporating information from published genetic data. A revised classification with 3 subgenera, 5 sections and 2 series is proposed.

Autores: Lepis, K.B.; Maas, P.J.M.; Struwe, L.
A new species from Gentianaceae (tribe Helieae) is described from northern Brazil. Sipapoantha obtusisepala sp. nov. is distinct from the previously single member of the genus, Sipapoantha ostrina, by having a woody and branched habit, sessile and ovate leaves with an acute apex, and a smaller calyx with circular lobes. Sipapoantha obtusisepala is based on somewhat incomplete material and tentatively placed in Sipapoantha based on the presence of key generic characters such as coriaceous leaves with strongly revolute margins and blue corollas. It has only been recorded from one locality in the Brazilian-Guyana border area in the state of Roraima.

Autores: McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Callaghan, B.; Vánky, K.; Scharaschkin, T.
The genera Ustilago, Sporisorium and Macalpinomyces are a polyphyletic complex of plant pathogenic fungi. The four main morphological characters used to define these genera have been considered homoplasious and not useful for resolving the complex. This study re-evaluates character homology and discusses the use of these characters for defining monophyletic groups recovered from a reconstructed phylogeny using four nuclear loci. Generic delimitation of smut fungi based on their hosts is also discussed as a means for identifying genera within this group. Morphological characters and host specificity can be used to circumscribe genera within the Ustilago-Sporisorium-Macalpinomyces complex.

The origin and evolution of the crown-group of turtles (Cryptodira + Pleurodira) is one of the most interesting topics in turtle evolution, second perhaps only to the phylogenetic position of turtles among amniotes. The present contribution focuses on the former problem, exploring the phylogenetic relationships of extant and extinct turtles based on the most comprehensive phylogenetic dataset of morphological and molecular data analyzed to date. Parsimony analyses were conducted for different partitions of data (molecular and morphological) and for the combined dataset. In the present analysis, separate analyses of the molecular data always retrieve Pleurodira allied to Trionychia. Separate analysis of the morphological dataset, by contrast, depicts a more...

A review is given of the literature on Desmanodon and Paratalpa. These two talpid genera can only be identified on the basis of the morphology of the humerus. Two species of Desmanodon, D. ziegleri n.sp. and D. burkarti n.sp., are described from the Lower Miocene of Anatolia. These species are considered ancestral to the Middle Miocene species of Anatolia. D. ziegleri is also a likely ancestor for the European species of Desmanodon. Desmanodon daamsi n. sp. is described from the Lower Miocene of Spain. The Desmanodon/Paratalpa finds from the Calatayud-Teruel basin (Spain) are discussed.

A new species, Asplenium riswanii (sect. Thamnopteris), is described from Central Java and West Papua, Indonesia. It is distinct from any known species by having thick and rigid fronds, abaxially keeled midribs, broadly lanceolate scales, and distantly spaced sori. Morphologically, A. riswanii is not similar to any species from Malesia but somewhat close to A. antrophyoides from mainland Southeast Asia. Molecular data reveal it has an isolated position in the phylogeny. The micromorphology of spores and leaf epidermis of A. riswanii is also documented and a key to the species of Asplenium sect.

This paper presents a summary of the current knowledge on the systematics of the Greek taxa of Chorthippus, morphologically characterised by angled lateral pronotal keels (usually grouped as Glyptobothrus). Prior to this paper, based on traditional morphology, ten taxa of Chorthippus with angled lateral pronotal keels were recognized from Greece. Based on morphology as well as (and more importantly so) bioacoustics thirteen Greek taxa are now recognised. With addition of a few additional related taxa that occur only outside Greece, all are treated in this paper: Chorthippus apricarius apricarius (Linnaeus, 1758), C. vagans vagans (Eversmann, 1848) (not in Greece), C. v. cypriotus (Uvarov, 1936) stat. nov.

During a survey of Penicillium spp. in soils from the diverse fynbos region in the Western Cape, South Africa, a number of previously undescribed species were isolated. Three of these belong to subg. Biverticillium sensu Pitt, recently incorporated into its previously associated teleomorph genus, Talaromyces s.str. These species displayed symmetrical biverticillate penicilli, acerose phialides and poor growth at reduced water activity, typical of this group. Morphological characters of the new species were compared to known Talaromyces species. The ITS and β-tubulin gene regions were used for phylogenetic comparisons, which confirmed the distinct nature of the three fynbos soil species described here as Talaromyces chloroloma sp. nov., T. ptychoconidium...

Gut structure of two species of the neotropical genus Tauritermes Krishna (Isoptera: Kalotermitidae)
Provedor de dados: 82
Autores: Godoy,Maria C.
Gut morphology of two species of the neotropical genus Tauritermes Krishna was analyzed. Detailed description of the coiling gut and the cuticular armature of the gizzard and first and second proctodeal segments of pseudergates are given. The characteristics of Tauritermes gut followed the pattern previously known for the family, but some differences among this genus and other Kalotermitidae genera were: the length of the midgut, the structure and cuticular ornamentation of the first and second proctodeal segments, the junction of the third and fourth proctodeal segments and the armature of the rectal valve. Tauritermes was differentiated from other Kalotermitidae genera by means of the gut characters, currently used in termite systematics and phylogeny.

Autores: Pinheiro,Daniela O.; Quagio-Grassiotto,Irani; Gregório,Elisa A.
The sugarcane borer, Diatraea saccharalis Fabricius, is a pest to sugarcane and many other crops. This work aims to characterize morphological variability in the epithelial cells (columnar, goblet and regenerative) along the midgut of D. saccharalis larvae. Fragments of the midgut (anterior, middle and posterior regions) were fixed and processed by light and scanning electron microscopy. There are both cytochemical and ultrastructural differences in the morphology of the epithelial cells, depending on their localization along the midgut. The apical surface of columnar cells shows an increase in both number and size of the apical protrusions from the anterior to the posterior midgut regions. There is an increase in the amount of PAS-positive (Periodic...

Autores: Romero-López,Angel; Morón,Miguel; Valdez,Jorge.
The external morphology of sensilla on the antennae of males and females of Phyllophaga ravida Blanchard is described using scanning electron microscopy. Sexual dimorphism in body and antennal dimensions and in antennal receptor types was found. The female's body is slightly larger than the male's, although male antennal lamellae are longer than in females. Sixteen types of sensilla were identified on the proximal and distal surfaces of lamellae from both sexes, most of them in males: three types of placodea sensilla, four types of auricilica sensilla, five types of basiconica sensilla, and four types of coeloconica sensilla. Also, two types of mechanoreceptor sensilla were present on the lamellae periphery. Furthermore, males had larger placodea,...

The metasternal and Brindley's Glands of Triatoma brasiliensis Neiva (Hemiptera: Reduviidae)
Provedor de dados: 82
Autores: Vitta,Ana Cristina R; Serrão,José E; Lima,Eraldo R; Villela,Evaldo F.
Triatoma brasiliensis Neiva is the most important vector of the Chagas' disease in the semiarid zones of North-eastern Brazil. Adult bugs have two main pairs of exocrine glands, the metasternal and the Brindley's glands, which release volatiles possibly with defense, alarm and/or mating functions. To date, anatomical and histological studies of the metasternal and the Brindley's glands in the genus Triatoma are scarce and, considering the relevance of these exocrine glands, the present work aimed at studying their morphology in T. brasiliensis. The metasternal and the Brindley's glands of T. brasiliensis consist of glandular units similar to those described for Rhodnius prolixus Stål and Panstrongylus megistus Burmeister, comprising a secretory apparatus,...

Ultramorphology and histology of the Polistes versicolor (Oliver) (Vespidae) thorax salivary gland compared with other Hymenoptera
Provedor de dados: 82
Autores: Rocha,Thalita; Caetano,Flávio H.
The salivary system of the Hymenoptera consists of the mandible, hypopharynx and thoracic salivary glands. It is very important because it is related to various aspects of the life of the insects, such as pheromone production, feeding the young, food digestion and nest building. Adult Polistes versicolor (Olivier) individuals were dissected, the thoracic salivary glands removed and processed for scanning electronic microscopy and histological examination. The P. versicolor thoracic salivary gland presents alveolar secretory units, consists of pseudoacines and does not have a reservoir. Four types of cells are present in the gland. The T1 and T2 cells make up the pseudoacines and differ mainly by the many secretory vessels in T2. There is a cluster of T3...

Comparative analysis of morphological, structural and morphometric patterns of Polistes versicolor (Olivier) (Hymenoptera: Vespidae) hypopharyngeal glands
Provedor de dados: 82
Autores: Britto,Fábio B.; Caetano,Flávio H.; Moraes,Regina L.M.S. de.
Using ultramorphological and histochemical techniques, this study describes the structural and morphological patterns of Polistes versicolor (Olivier) hypopharyngeal glands, comparing them with patterns of other Hymenopteran groups. Besides, the presence of intra-specific variation was evidenced by morphometric analysis of the secretory cells in wasps with different ages. The studied species presented glands with primitive characteristics, with secretory cells discharging individually in the hypopharyngeal plate. The morphological pattern found in hypopharyngeal glands was basically the same for all studied wasps, however, the length of glandular cells showed significant variations between individuals. Apparently these variations are not related with age.

Several studies have focused on understanding the biochemistry and morphology of the fat body of the hematophagous mosquito Aedes aegypti (L.) (Diptera: Culicidae). In contrast, few studies, if any, have focused on morphological characters of the fat body in other mosquitoes, especially non-hematophagous taxa such as the culicid Toxorhynchites. Larvae of Toxorhynchites prey upon the larvae of other mosquito species and are used in vector mosquito control. We investigated aspects of the fat body trophocytes, including the morphometric analyses of the lipid droplets, protein granules and nuclei, during Toxorhynchites theobaldi (Dyar &amp;amp; Knab) post-embryonic development.

Alternative techniques to study characters of the genitalia in Lepidoptera
Provedor de dados: 82
Autores: Dias,Fernando M S; Casagrande,Mirna M; Mielke,Olaf H H.
The present note aims to describe two alternative methods for observing genitalia in Lepidoptera. The first one provides means to examine both male and female genitalia without spoiling the scales of the abdomen, preserving it attached to the thorax and aesthetically similar to an unexamined specimen. The second one provides ways of observing certain characters on the male genitalia in a non-destructive way, and does not depend on time-consuming removing and dissection of the abdomen. It is expected that the presented techniques will help on morphological studies and on identifying similar species which consistently differ in genitalic armatures.

Morphological variation among populations of Hemigrammus coeruleus (Characiformes: Characidae) in a Negro River tributary, Brazilian Amazon
Provedor de dados: 83
Autores: Lazzarotto,Henrique; Barros,Thiago; Louvise,José; Caramaschi,Érica Pellegrini.
ABSTRACT We explored patterns of phenotypic variation in Hemigrammus coeruleus from the Unini River basin, a blackwater river in the Brazilian Amazon. Geometric morphometrics was used to evaluate variation in body shape among populations from four tributaries (UN2-UN5). We found no evidence for sexual dimorphism in body size and shape. However, morphological differences among populations were detected as the analyses recovered significant groups corresponding to each sub-basin, with some overlap among them. The populations from UN2, UN3 and UN5 had more elongate bodies than fish from UN4. The most morphologically divergent population belonged to UN4, the tributary with the most divergent environmental conditions and the only one with seasonally-muddy...

Phylogeny of the family Characidae (Teleostei: Characiformes): from characters to taxonomy
Provedor de dados: 83
Autores: Mirande,Juan Marcos.
The family Characidae is the most diverse among Neotropical fishes. Systematics of this family are mainly based on pre-cladistic papers, and only recently a phylogenetic hypothesis for Characidae was proposed by the author. That phylogeny was based on 360 morphological characters studied for 160 species, including representatives of families related to Characidae. This paper is based on that phylogenetic analysis, with the analyzed characters described herein and documented, accompanied by comparisons of their definition and coding in previous papers. Synapomorphies of each node of the proposed phylogeny are listed, comparisons with previous classifications provided, and autapomorphies of the analyzed species listed. Taxonomic implications of the proposed...

DNA barcode of Parodontidae species from the La Plata river basin - applying new data to clarify taxonomic problems
Provedor de dados: 83
Autores: Bellafronte,Elisangela; Mariguela,Tatiane Casagrande; Pereira,Luiz Henrique Garcia; Oliveira,Claudio; Moreira-Filho,Orlando.
In the past years, DNA barcoding has emerged as a quick, accurate and efficient tool to identify species. Considering the difficulty in identifying some Parodontidae species from the La Plata basin and the absence of molecular data for the group, we aimed to test the effectiveness of DNA barcoding and discuss the importance of using different approaches to solve taxonomic problems. Eight species were analyzed with partial sequences of Cytochrome c oxidase I. The mean intraspecific K2P genetic distance was 0.04% compared to 4.2% for mean interspecific K2P genetic distance. The analyses of distance showed two pairs of species with K2P genetic divergence lower than 2%, but enough to separate these species. Apareiodon sp. and A. ibitiensis, considered as the...

Structural analysis of the Pimelodus maculatus (Lacépède, 1803) embryogenesis (Siluriformes: Pimelodidae)
Provedor de dados: 83
Autores: Buzollo,Hellen; Veríssimo-Silveira,Rosicleire; Oliveira-Almeida,Isângela R.; Alexandre,Juliana S.; Okuda,Hélio T.; Ninhaus-Silveira,Alexandre.
The fish embryonic development comprises the events between the egg fertilization up to larvae hatching, being useful for the identification of viable eggs in productivity and survival studies as well as in raising experiments of several species. The goal of the present study was to characterize the embryonic development of Pimelodus maculatus (Siluriformes; Pimelodidae). The embryogenesis was typical of teleosteans, but with differences in relation to other species such as duration of development, type of blastocoel, moment of somite segmentation among others. Six stages of embryonic development were defined: zygote, cleavage, blastula, gastrula, organogenesis (divided in phases: early segmentation and late segmentation) and hatching with a period of...

Testing the ecomorphological hypothesis in a headwater riffles fish assemblage of the rio São Francisco, southeastern Brazil
Provedor de dados: 83
Autores: Casatti,Lilian; Castro,Ricardo M. C.
The ecomorphology of 14 fish species resident in a headwater riffles area of the São Francisco river, southeastern Brasil, was analyzed and combined with diet and feeding behavior data, previously obtained by us. The three larger species groups formed in the ecomorphological analysis were found to reflect primarily microhabitat occupation in the following manner: a) nektonic characids with compressed bodies, lateral eyes and lateral pectoral fins, with diurnal and opportunistic feeding habits (Astyanax rivularis, Bryconamericus stramineus, and Bryconamericus sp.); b) nektobenthic characiforms and siluriforms with fusiform bodies and expanded pectoral fins, including sit-and-wait characidiins, predators of aquatic insect larvae (Characidium fasciatum and...

Comparative analysis of spermiogenesis and sperm ultrastructure in Callichthyidae (Teleostei: Ostariophysi: Siluriformes)
Provedor de dados: 83
Autores: Spadella,Maria A.; Oliveira,Claudio; Quagio-Grassiotto,Irani.
In Corydoradinae, the presence of spermatids in the lumen of the testicular tubules together with spermatozoa suggests that spermatogenesis is of the semicystic type, whereas in Callichthyinae, sperm production occurs entirely within spermatocysts in the germinal epithelium, characterizing cystic spermatogenesis. Spermiogenesis in Callichthyinae is characterized by an initial lateral development of the flagellum, the presence of nuclear rotation to different degrees, an eccentric or medial formation of a nuclear fossa, formation of a cytoplasmic channel, and presence of centriolar migration, being more similar to type I spermiogenesis. In Corydoradinae, spermiogenesis is characterized by eccentric development of the flagellum, the absence of nuclear...

Karyotypic and morphological divergence between two cryptic species of Eigenmannia in the Amazon basin with a new occurrence of XX/XY sex chromosomes (Gymnotiformes: Sternopygidae)
Provedor de dados: 83
Autores: Silva,Danillo S.; Peixoto,Luiz A. W.; Pieczarka,Julio C.; Wosiacki,Wolmar B.; Ready,Jonathan S.; Nagamachi,Cleusa Y.
Eigenmannia species are widely distributed in the Neotropics, with eight valid species currently recognized. Populations of Eigenmannia from three locations in the eastern Amazon were investigated using cytogenetic and morphological techniques, revealing two taxa designated here as Eigenmannia sp. "A" and Eigenmannia sp. "B". The species differ in three morphometric characters, two meristic characters, and one osteological character. Eigenmannia sp. "A" presents 2n = 34 (22 m/sm+12 st/a) and Eigenmannia sp. "B" presents 2n = 38 (14 m/sm+24st/a) and simple differentiated sex chromosomes of the type XX/XY. In both species the Constitutive Heterochromatin (CH) rich in A-T bases is distributed in the centromeric region of all chromosomes. Eigenmannia sp. "B"...

Provedor de dados: 83
Autores: Costa,Raphael S.; Souza,Fabrício M. S. de; Senhorini,José A.; Veríssimo-Silveira,Rosicleire; Ninhaus-Silveira,Alexandre.
ABSTRACT This study evaluated the effect of the cryoprotectants and the low temperatures on the embryonic development of Prochilodus lineatus, describing their main morphological alterations. On chilling sensitivity test, the survival rates at the twenty somites stage (20S) were 53.6% at 0ºC, and 100% in 5ºC. To test toxicity, the embryos were exposed to a graded series of 1,2-Propanediol (PROP), dimethyl sulfoxide (Me2SO4) and glycerol (GLY), terminating in a solution of high osmolarity. There was no significant difference in the embryos survival of toxicity test between series of PROP and Me2SO4 in the 6S and 20S. In the cooling protocols, were evaluated the effects of low temperature associated with cryoprotectants. At 5ºC, PROP showed survival rates...

A new species of Paralithoxus (Siluriformes: Loricariidae: Ancistrini) from the highlands of Serra da Mocidade, Roraima State, Brazilian Amazon
Provedor de dados: 83
Autores: Rapp-Py-Daniel,Lúcia; Oliveira,Andreza S.; Bastos,Douglas A.; Ito,Priscila Madoka M.; Zuanon,Jansen; Briglia-Ferreira,Sylvio Romério.
ABSTRACT A new species of Paralithoxus is described from the Ajarani River, a small tributary of the Branco River basin, Roraima State, Brazilian Amazon. The genus Paralithoxus comprises species described from the Essequibo drainage in Guyana, Approuague and Maroni in French Guiana, Suriname River in Surinam, and more recently, from Jari and Amapá rivers, in Brazil. Despite occurring in a rock-bottomed fast-flowing stream as the other species of Paralithoxus, this is the first species of the genus collected at 900 m altitude, in the Serra da Mocidade highlands, an isolated and poorly accessible small mountain chain at the southern border of the Guiana Shield. The new species is distinguished from its congeners by having truncate teeth, color pattern with...

A macroscopic classification of the embryonic development of the one-sided livebearer Jenynsia multidentata (Teleostei: Anablepidae)
Provedor de dados: 83
Autores: López-Rodríguez,Nathalia C.; Barros,Cíntia M. de; Petry,Ana Cristina.
ABSTRACT This study proposes eight stages according to the main discernible changes recorded throughout the embryonic development of Jenynsia multidentata. The development of morphological embryo structures, pigmentation, and changes in tissues connecting mother and embryo were included in the stage characterization. From the fertilized egg (Stage 1), an embryo reaches the intermediary stages when presenting yolk syncytial layer (Stage 2), initial pigmentation of the outer layers of the retina and dorsal region of the head (Stage 3), and the sprouting of the caudal (Stage 4), dorsal and anal fins (Stage 5). During the later stages, the ovarian folds enter the gills, and the body pigmentation becomes more intense (Stage 6), the body becomes elongated (Stage...

Systematic assessment of the Leporinus desmotes species complex, with a description of two new species
Provedor de dados: 83
Autores: Burns,Michael D.; Chatfield,Marcus; Birindelli,José L. O.; Sidlauskas,Brian L.
ABSTRACT Members of the Leporinus desmotes species complex can be distinguished from other barred or banded congeners by the combination of nine distinct black bars across the head and trunk and long, pointed, laterally compressed and upward curving symphyseal dentary teeth. A taxonomic reassessment of this complex revealed two new species, one from the Orinoco and Negro rivers of Venezuela and Brazil, and the other from the Xingu and Tapajós rivers of Brazil. Both species are similar to L. desmotes and L. jatuncochi, but differ significantly in body shape morphology, coloration, and/or circumpeduncular scale counts. Genetic evidence also contributes to the recognition of both new species. This contribution also maps the geographic distribution of the four...

The South American and Australian percichthyids and perciliids. What is new about them?
Provedor de dados: 83
Autores: Arratia,Gloria; Quezada-Romegialli,Claudio.
ABSTRACT A study including morphological characters and mitogenomics of South American and Australian fishes previously assigned to Percichthyidae was conducted. Results generated from these different data sets reveal major disagreements concerning the content and interpretation of the so-called percichthyids. A phylogenetic analysis based on 54 morphological characters suggests the existence of two major clades: (1) Percichthyidae, including the South American Percichthys and the Australian taxa Macquaria australasica, Macquaria (= Plectroplites), and Maccullochella; (2) Perciliidae with the South American genus Percilia at the base plus more advanced Australian genera Nannoperca, Nannatherina, Bostockia, and Gadopsis. In contrast, molecular and...

Autores: Assumpção,Lucileine de; Makrakis,Maristela Cavicchioli; Makrakis,Sergio; Wagner,Ricardo Luiz; Silva,Patrícia Sarai da; Lima,Ariane Furtado de; Kashiwaqui,Elaine Antoniassi Luiz.
This study investigated the external body morphology (based on morphometric data) and the swimming efficiency in fish passages (based on the ascent time in a fish ladder) of two Neotropical long-distance migratory species. The fish were collected in the fish ladder of the Porto Primavera Hydroelectric Power Plant (known as Engenheiro Sergio Motta), upper Paraná River, Brazil. The species differ in several morphometric ratios related to swimming performance. Prochilodus lineatus exhibited a higher muscle ratio and caudal fin length ratio. However, Leporinus elongatus showed higher values for the fineness ratio, a higher length from snout to pectoral fin base ratio, and a higher caudal peduncle depth factor. Although both species show good swimming...

Ontogenetic development of Heterocharax macrolepisEigenmann (Ostariophysi: Characiformes: Characidae) with comments on the form of the yolk sac in the Heterocharacinae
Provedor de dados: 83
Autores: Mattox,George M. T.; Hoffmann,Martin; Hoffmann,Peter.
Fishes in early developmental stages frequently have morphological features that differ from those of adult stages, and many characters found later in ontogeny are not available in initial stages. Hence, morphological descriptions of early stages are useful to provide information for the identification of eggs and larvae, a knowledge still restricted among Neotropical fishes. We studied the development of Heterocharax macrolepis, a heterocharacine whose adult specimens from the aquarium trade were kept and spawned at around 23-24ºC. A developmental series of 51 specimens was preserved, ranging from 3.2 mm notochord length to 18.6 mm standard length, covering approximately the first 73 days post-hatching. We described the development of main morphological...

Is coexistence between non-native and native Erythrinidae species mediated by niche differentiation or environmental filtering? A case study in the upper Paraná River floodplain
Provedor de dados: 83
Autores: Pereira,Larissa S.; Mise,Fábio T.; Tencatt,Luiz F. C.; Baumgartner,Matheus T.; Agostinho,Angelo A.
ABSTRACT The limiting similarity theory predicts that divergence in the functional traits of native and introduced species is an essential component in species establishment, as introduced species must occupy a niche that is unoccupied by resident species. On the other hand, the environmental filtering hypothesis predicts convergence between introduced and native species, as both possess traits that make them adapted to the local abiotic environment. Morphology, spatial co-occurrence, diet, feeding selectivity, and niche breadth and overlap of Erythrinidae were evaluated to detect possible mechanisms acting in the coexistence between non-native and native species. Native (Hoplias sp. B and Hoplias cf. malabaricus) and non-native (Hoplerythrinus...

Otomorphs (= otocephalans or ostarioclupeomorphs) revisited
Provedor de dados: 83
Autores: Arratia,Gloria.
ABSTRACT A morphological revision is presented here on the cohort Otomorpha, a clade currently interpreted as the most primitive among the large supercohort Clupeocephala. Otomorpha is a morphologically heterogeneous group represented by clupei forms , alepocephaliforms, and ostariophysans (gonorynchiforms, cypriniforms, characiforms, siluriforms, and gymnoti forms) that inhabit various marine and freshwater environments worldwide. Otomorphs have a long (ca. 145 Ma) and diverse fossil record. They are the largest fish teleostean clade worldwide, as well as the largest of the Neotropical Region. While molecular studies strongly confirm the monophyly of Otomorpha, most potential morphological synapomorphies of the group become homoplastic largely due to the...

Autores: Pessanha,André Luiz Machado; Araújo,Francisco Gerson; Oliveira,Ronnie Enderson M. C. C.; Silva,Adna Ferreira da; Sales,Natalice Santos.
Eleven ecomorphological attributes and diet of seventeen juvenile fish species were examined to test the hypothesis that morphological patterns determine resource uses in estuarine habitats. Species were separated according to the apparatus to food capture and habitat use (benthic or pelagic) in three different groups: (1) a group with depressed fish body, strong caudal peduncle and enlarged pectoral fins; (2) a second group laterally flattened with a wide protruding mouth, and (3) a third group strongly flattened with small pectorals fins. The following six trophic groups were organized based on prey categories: Zooplanktivores, Benthivores, Omnivores, Detritivores, Macrocarnivores and Insectivores. Significant results (PERMANOVA) between ecomorphological...

Abstract Functional traits are important for understanding the links between species occurrence and environmental conditions. Identifying these links makes it possible to predict changes in species composition within communities under specific environmental conditions. We used functional traits related to habitat use and trophic ecology in order to assess the changes in fish community composition between streams with varying habitat structure. The relationship between the species traits and habitat characteristics was analyzed using an RLQ ordination analysis. Although species were widely distributed in habitats with different structures, physical conditions did favor some species based on their functional characteristics. Eight functional traits were...

Autores: Sánchez,Roberto Omar; Martínez,Virginia Haydee.
ABSTRACT Otoliths are three pairs of calcareous structures found in the inner ear of bony fish. In many cases they display a species-specific morphology. The present study describes morphological variations of otoliths, namely lapillus, asteriscus and sagitta, of eleven species belonging to four loricariid subfamilies. Otolith structures that characterize the Loricariidae and some of its subfamilies are presented. The sagitta exhibit a specific morphology that is not found in other siluriform families; it is claviform with a tapered posterior region and a flared anterior one. In the latter, central elevations are observed and the dorsal wings are continuous with lateral expansions named basal wings. Hypoptopomatinae and Loricariinae as well as Hypostominae...

Autores: Andrade,Fernanda F.; Lima,Ariane F.; Assumpção,Lucileine; Makrakis,Sergio; Kasai,Rodrigo I. D.; Makrakis,Maristela C.
ABSTRACT This study described the initial development of Pseudoplatystoma reticulatum, as well as changes in growth patterns. Morphometric and meristic variables were analyzed during embryonic, larval and juvenile periods, even as allometric growth coefficients for larvae and juveniles. Eggs showed an average diameter of 1.79 mm and broad perivitelline space (23.41%). The total length (TL) of the larvae ranged from 3.05 to 25.72 mm, and the total number of myomeres ranged from 45 to 50 (preanal = 13-16 and postanal = 30-35). Initial pigmentation is poor, concentrated at the extremities of the yolk sac. In the flexion stage, the pigmentation intensifies and forms a longitudinal stripe extending from the snout to the operculum and two longitudinal stripes on...

Spermatozoa and spermiogenesis ultrastructure were studied in the serrasalmine species Piaractus mesopotamicus, Mylossoma duriventre, Serrasalmus maculatus, and Metynnis mola and two distinct patterns may be recognized: the first common to Mylossoma, Serrasalmus and Metynnis, and the other, characteristic of Piaractus. The latter pattern is more similar to the conditions found in Salminus and Brycon. On the other hand, serrasalmine spermatozoa also share characteristics with the spermatozoa of species of the superfamily Anostomoidea. The phylogenetic significance of these characters is discussed.

Autores: Kubicek,Kole M.; Álvarez-González,Carlos Alfonso; Martínez-García,Rafael; Contreras-Sánchez,Wilfrido Miguel; Pohlenz,Camilo; Conway,Kevin W.
ABSTRACT We document for the first time the early ontogeny of Centropomus poeyi based on captive raised material representing 0-19 days posthatch (dph). The achievement of early developmental landmarks (i.e., yolk-sac depletion, flexion, development of fins) and changes in pigmentation are described (1.4 mm NL-10.6 mm SL; 0-19 dph) and documented for a subset of individuals using high quality photographs. The ontogeny of the viscerocranium is also described (2.4 mm NL-10.6 mm SL; 6-19 dph). Development in C. poeyi occurs over a short period with attainment of the juvenile stage (i.e., full complement of fin rays present in each fin) occurring by 6.9 mm SL. The ontogeny of external pigmentation in C. poeyi is marked by two trends throughout growth: (1) a...

An appraisal of the phylogenetic relationships of Hypoptopomatini cascudinhos with description of two new genera and three new species (Siluriformes: Loricariidae)
Provedor de dados: 83
Autores: Delapieve,Maria Laura S.; Lehmann A,Pablo; Reis,Roberto E.
ABSTRACT The discovery of three new taxa of Hypoptotopomatini with ambiguous generic assignment prompted a reanalysis of the phylogenetic relationships of the tribe. The analysis focused on a data matrix of 56 terminals and 107 morphological characters comprising the three new taxa, most species of Hypoptopoma and Otocinclus, and all other species of the tribe. The 162 maximally parsimonious trees of 382 steps, consistency index of 0.41, and retention index of 0.83 were then summarized in a strict consensus tree. The results confirm the monophyly of the Hypoptopomatini, recover four genera as monophyletic (Acestridium, Hypoptopoma, Niobichthys, and Otocinclus), revealed Hypoptopoma and Oxyropsis to be non-monophyletic; and revealed two new genera within...

Phylogenetic relationships of the enigmatic Carlastyanax aurocaudatus (Eigenmann) with remarks on the phylogeny of the Stevardiinae (Teleostei: Characidae)
Provedor de dados: 83
Autores: Mirande,Juan Marcos; Jerep,Fernando Camargo; Vanegas-Ríos,James Anyelo.
The monotypic genus Carlastyanax Géry was defined to include Astyanax aurocaudatus, a morphologically odd species having, among other features, four teeth in the posterior premaxillary row and eight branched dorsal-fin rays. Later on, the characters used to define Carlastyanax were considered as invalid and this genus was synonymized with Astyanax. In this paper, we include Astyanax aurocaudatus in a phylogeny of the Characidae and obtain a sister-group relationship between this species and Creagrutus, within the Stevardiinae. The resurrection of Carlastyanax as a valid genus is therefore proposed. The analysis presented is the largest phylogeny of the Stevardiinae so far published. Relationships of this subfamily are also discussed.

The blind catfish from the caves of Chapada Diamantina, Bahia, Brazil (Siluriformes: Heptapteridae): description, anatomy, phylogenetic relationships, natural history, and biogeography
Provedor de dados: 83
Autores: Bockmann,Flávio A.; Castro,Ricardo M. C.
Rhamdiopsis krugi, a new troglobitic heptapterid catfish, is described from the caves of Chapada Diamantina, State of Bahia, northeastern Brazil. This species, although frequently cited in the scientific literature along the last seventeen years, remained undescribed largely due to its uncertain phylogenetic affinities. The generic assignment of R. krugi was clouded largely by its high number of unusual morphological features (some related to cave life), for instance: absence of eyes and body pigmentation; presence of a widely exposed pseudotympanum; posterior border of the anterior branch and anterior margin of the arborescent portion of the posterior branch of the transverse process of fourth vertebra joined; dorsal hypural plate commonly with seven...

There are few reports describing the structure and function of the whale placenta with the advance of pregnancy. In this study, therefore, the placenta and nonpregnant uterus of the Antarctic minke whale were observed morphologically and immunohistochemically. Placentas and nonpregnant uteri were collected from the 15th, 16th and 18th Japanese Whale Research Programme with Special Permit in the Antarctic (JARPA) and 1st JARPA II organized by the Institute of Cetacean Research in Tokyo, Japan. In the macro- and microscopic observations, the placenta of the Antarctic minke whale was a diffuse and epitheliochorial placenta. The chorion was interdigitated to the endometrium by primary, secondary and tertiary villi, which contained no specialized trophoblast...

Autores: Simone,Luiz Ricardo L.; Penchaszadeh,Pablo E.
The redescription of Hiatella meridionalis (d’Orbigny, 1846) is provided as first attempt to improve the systematics of the genus in the regions of Atlantic and western Pacific. This reanalysis is based on specimens collected in the vicinity of the type localities and is based on detailed morphology of samples that some researches consider a single, wide ranging species. From the morphological characters, the more interesting are: a high quantity of papillae at incurrent siphon; the retractor muscles of siphon divided in two bundles; the small size of the palps; the muscular ring in the stomach; and the zigzag fashion of the short intestinal loops. These characters distinguish the species from the other hiatellids so far examined. Type material of the...

ABSTRACT Exocrine glands play important role in social organization of insects, such as caste and inter-caste differentiation. Due their functional and structural plasticity, morphological studies on such glands contribute to better understanding the biology of social bees. Therefore, the aim of the study was to characterize the sequence of the post-embryonic development of intramandibular glands of Friesella schrottkyi (Friese, 1900) (Hymenoptera: Apidae) workers using histological and histochemical analyses. The mandibles of pupae at different developmental stages and newly emerged adults were analyzed. The intramandibular glands of F. schrottkyi presented two types: class I glands, in the mandible epidermis and class III glands, inside the mandible...

New species of titi monkey, genus Callicebus Thomas, 1903 (Primates, Pitheciidae), from Southern Amazonia, Brazil
Provedor de dados: 84
Autores: Dalponte,Julio César; Silva,Felipe Ennes; Silva Júnior,José de Sousa e.
The genus Callicebus is one of the most diverse Neotropical primate groups, with 31 recognized species. However, large knowledge gaps still exist regarding the diversity of this genus. Such gaps are gradually being filled due to recent intensification of sampling efforts. Several geographic distributions have been better delimited, and six new species have been described in the last 15 years. The goal of the present study is to describe a new species of Callicebus belonging to the Callicebus moloch species group, recently discovered in an area previously considered to be part of the geographic distribution of C. cinerascens. Data collection was conducted through direct observations, specimen collection and interviews with local residents during four...

Abstract Helicina variabilis Wagner, 1827 (Neritimorpha, Helicinidae) is redescribed based on a sample collected in Nanuque, northern Minas Gerais, Brazil. The species description, previously based only on the shell, is expanded to the phenotypic features. The study revealed absorption of the internal shell whorls; a diaphragm muscle connected to the floor of the pallial cavity; a monoaulic pallial oviduct, with the female genital aperture inside the anal aperture, and the lack of a seminal receptacle and provaginal sac; and the pleural ganglia of the nerve ring connected with each other. The significance of these findings is discussed in the light of current taxonomic and phylogenetic knowledge.

Autores: Almeida,Rony Peterson Santos; Leite,Luis Anderson Ribeiro; Ramos,Kelli dos Santos.
Abstract Two new records of gynandromorphs in Xylocopa Latreille, 1802 (Hymenoptera, Apidae). Gynandromorphs are deviant morphological individuals with genetically distinct male and female tissues. Records of sex anomalies seems to be important to better understand the mechanisms regulating phenotypic expression. Herein, two new cases of gynandromorphs in carpenter bee species of Xylocopa from Brazil are described and figured: a mixed gynandromorph of the X. (Neoxylocopa) brasilianorum (Linnaeus, 1767) from São Paulo and a bilateral gynandromorph of the X. (Neoxylocopa) ordinaria Smith, 1874 from Sergipe.

The characters defining Mecosarthron Buquet, 1840 and Xixuthrus Thomson 1864 are discussed, along with a historical review of the literature that described and classified these taxa. Through morphological examination of these genera and most of the included species, we addressed the systematic placement of Xixuthrus domingoensis Fisher, 1932 that was placed in Mecosarthron by Ivie (1985). We restore its placement in the genus Xixuthrus. The first description of the female of X. domingoensis is provided, along with comparative redescriptions of Mecosarthron gounellei (Lameere, 1903), and M. buphagus Buquet, 1840. We include a key to the species currently in Mecosarthron.

Morphology and vocalization support specific status of the Chestnut-headed Chachalaca, Ortalis motmot ruficeps (  ) (Aves; Galliformes; Cracidae)
Provedor de dados: 84
Autores: Tomotani,Barbara Mizumo; Silveira,Luís Fábio; Pacheco,José Fernando.
Abstract The Little Chachalaca (Ortalis motmot) is a widely distributed species in the Amazon basin, typically found in riverine habitats. There are two disjunct populations: the northern O. m. motmot and the southern O. m. ruficeps (known as Chestnut-headed Chachalaca). Here we performed a vocal, morphological and plumage comparison between these two taxa. Birds present differences in tail coloration but are otherwise undiagnosable in terms of plumage. Ortalis m. ruficeps is, however, markedly smaller and lighter than O. m. motmot, with no overlap in size or weight. We also found vocal differences between O. m. motmot and O. m. ruficeps, no overlap in geographic distributions and no signs of hybridization across its range. Based on the available data,...

Provedor de dados: 84
Autores: Nascimento,Fabio Oliveira do.
The Geoffroy's cat Leopardus geoffroyi (d'Orbigny &amp;amp; Gervais, 1844) is a small cat found in the Southern Cone of South America and, depending on the author, four or five subspecies have been usually recognized (L. g. geoffroyi, L. g. paraguae, L. g. euxanthus, L. g. salinarum and L. g. leucobaptus), mainly based on external morphological characters, such as color pattern of the pelage. In order to clarify the taxonomy of L. geoffroyi, I analyzed approximately 200 specimens housed in museums. I have examined the external and craniodental morphology in quantitative and qualitative terms in the search for patterns of congruent characters that would indicate the existence of taxonomic units. Twenty craniodental measurements were taken and tested by...

Delimitation of Azadirachta indica A. Juss. from Melia azedarach L. (Meliaceae Juss.) based on leaf morphology
Provedor de dados: 85
Autores: Abdel-Hameed,Usama K.
In Egypt there are two different species that are commercially marketed under the same trade name of Neem: one is Azadirachta indica A. Juss., and the other is Melia azedarach L. In this paper, leaf morphological characters (e.g., lamina architecture, stomatography, petiole and blade micromorphology) of both taxa were described and illustrated to aid in the identification and differentiation between the two misidentifed taxa. The obtained results concluded that leaf morpho-anatomical characters will not only provide criteria for their correct taxonomic authentication, but would also serve as future standard data for the quality assessment of the pharmaceutical preparation of botanical drugs.

Autores: Lemos,J.P.; Galvão,J.C.C.; Silva,A.A.; Fontanetti,A.; Cecon,P.R.; Lemos,L.M.C.
Mowing is one of the most important methods used to control weeds in organic farming, under the no-tillage system. This study aimed to evaluate the effects of three weed management techniques on weed development, using the weeds Bidens pilosa and Commelina benghalensis, in competition with organic corn {mowing at the three-leaf stage (14 days after corn emergence - DACE), mowing at the three- and six-leaf stage (14 and 25 DACE), and no mowing. Single cultivation with no mowing was also evaluated for these weeds. Mowings performed at 14 and 25 DACE prevented the production of B. pilosa seeds, ensuring efficient control of this species. However, the use of this technique was shown to be inefficient in the control of C. benghalensis.

Provedor de dados: 88
Autores: Guimarães,Silvia M.P.B.; Horta,Paulo A.
The coast of Espirito Santo State is located in a biogeographic transition zone presenting high diversity. A renewed interest in this region occurred in the 1990s, resulting in various new records and new species descriptions added to the Brazilian marine flora. The study of the infralitoral of this region is just beginning, and a detailed exploration with use of Scuba diving is revealing a flora containing many little-known taxa, particularly of red algae. As a first result, Predaea feldmannii Børgesen is being described for the Brazilian coast. The occurrence of the genus Predaea in Brazil has been considered with restriction since representatives of this genus had been referred only once by Howe &amp;amp; Taylor in 1931, being first considered as...

Autores: FUJII,MUTUE TOYOTA; COCENTINO,ADILMA L.M.; PEREIRA,SONIA M. B.
Morphological studies on Ceramium nitens (C. Agardh) J. Agardh, a completely corticated species, were carried out based on specimens rediscovered in Brazil fifty years after its first record. Its occurrence in Brazil was considered doubtful since it had been collected only once since 1945. Ceramium nitens can be recognized by having axial cells entirely covered by cortical cells, except for the cells near the apex, obscuring the nodal and internodal banding thalli, characteristic of most Ceramium species. In this paper the occurrence of Ceramium nitens in Brazil is confirmed and its vegetative and tetrasporangial structures are described in detail and their implications for the taxonomy of the genera Ceramium, Centroceras and Corallophila are discussed....

ABSTRACT The aim of this study was to evaluate the possible effects of glutamine and broiler breeder age on the development of intestinal mucosa in broiler chicks during first week of age. For this purpose, 32 one-day-old broiler chicks were distributed according to a completely randomized experimental design in a 2 x 2 factorial arrangement. Treatments consisted of two broiler breeder ages (30 and 60 weeks) and two dietary glutamine supplementation levels (0% and 1%). The morphological development of intestinal mucosa, particularly villus height and crypt depth, was evaluated. The results showed that the supplementation with 1% of glutamine influenced the development of villus height in the duodenum (p=0.009), jejunum (p = 0.006), and ileum (p = 0.001),...

Autores: Santos,MMAB; Peiró,JR; Meireles,MV.
Avian cryptosporidiosis has been reported in more than 30 species of birds. To date, the species infecting birds are C. baileyi, C. galli and C. meleagridis. In this study, the morphological, clinical and molecular characteristics of a Brazilian ostrich isolate of Cryptosporidium are described. The oocysts of this Brazilian isolate are larger and more elongated than those of Cryptosporidium previously reported in ostriches, which were morphologically similar to C. meleagridis. Morphological, biological and molecular analyses demonstrated similarity of this ostrich isolate with C. baileyi, suggesting that there are at least two Cryptosporidium species infecting ostriches; one with molecular, biological and morphological characteristics related to C....

Provedor de dados: 89
Autores: Norouzian,H; Alirezaei,M; Dezfoulian,O; Taati,M.
ABSTRACT The capacity of the chicken intestinal tract to digest and absorb nutrients is not fully developed on the day of hatch. The aim of this study was to investigate the role of betaine on the intestinal development of broiler chickens, including brush border enzyme activities indices and morphological changes during the first week of growth. Fiftyone-day-old Ross 308 broiler chickens were randomly distributed into five groups: control (C), low methionine(LM), low methionine plus betaine (LM+B), betaine 1 (B1) and betaine 2 (B2). Betaine was dissolved with a concentration of 500 mg/L in the drinking water of LM+B and B1groups and a concentration of 1000 mg/L in the B2 group. Histological assessment showed lower duodenal crypt depth and villi...

ABSTRACT The intra-puparial development of the blowflies Cochliomyia macellaria (n = 310) and Lucilia cuprina (n = 470), was studied under controlled conditions in laboratory. The 3rd instar larvae were reared until they stopped feeding, and the pre-pupae were separated according to the size in larval length and degree of pigmentation and of the cuticle. We observe a set of five continuous events or phases: (1) pupariation, (2) larva-pupa apolysis, (3) cryptocephalic pupa, (4) phanerocephalic pupa and (5) pharate adult. The total time of the intra-puparial development, larva-pupa apolysis to pharate adult, lasted for 120 h (5 days) to C. macellaria and 210 h (8.75 days) to L. cuprina.

Autores: Fernandes,Elania; Araujo,Elton; Souza,Itala; Souza,Mariana; Nunes,Glauber.
ABSTRACT The gregarious endoparasitoid Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a natural enemy of fruit flies. This parasitoid was previously used to successfully control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Hawaii, USA. Despite its importance in the control of fruit fly pests, little is known about the development or characteristics of its preimaginal stages. The aim of this study was to observe the development and morphologically characterize the immature stages of Tetrastichus giffardianus. Tetrastichus giffardianus individuals were reared on C. capitata larvae/pupae under laboratory conditions at a temperature of 25 ± 2 °C, relative humidity of 60 ± 10%, and 12-h photophase. Third-instar C. capitata larvae...

Provedor de dados: 92
Autores: Mermudes,José Ricardo M.; Napp,Dilma Solange.
In order to investigate the affinities of the hitherto considered Neotropical Cleomenini genera, a detailed morphological comparative study was carried out based on representatives of their type species and other congeneric species. The results, when compared with representatives of Cleomenes Thomson and other non Neotropical Cleomenini genera together with representatives of Rhopalophorini Blanchard and Rhinotragini Thomson, show that: 1) Listroptera Audinet-Serville, 1834, Dihammaphora Chevrolat, 1859, Haenkea Tippmann, 1953, Aguassay Napp &amp;amp; Mermudes, 2001 and Timabiara Napp &amp;amp; Mermudes, 2001 form a very homogeneous group, not related to other Cleomenini, but sharing several synapomorphies with the Rhopalophorini; therefore they are herein...

Provedor de dados: 92
Autores: Couri,Márcia S.; Carvalho,Claudio J. B. de; Pont,Adrian C.
Cordiluroides Albuquerque is a genus of Neotropical Coenosiinae (Muscidae), known from six species. The genus is here recorded for the first time from Costa Rica, on the basis of three species: C. listrata Albuquerque, 1954, C. insularis (Willliston, 1896) and C. bistriata (Wulp, 1896) sp. rev.. We provide a key for the identification of these Costa Rican species, redescribe and illustrate their external morphological characters and terminalia. C. bistriata and C. vittifera (Stein, 1904) are both considered to be good species and are re-instated from the synonymy of C. insularis. The type material of C. listrata (Museu Nacional, Rio de Janeiro), of C. insularis and C. bistriata (The Natural History Museum, London) and of C. vittifera (Museum für...

Saving our science from ourselves: the plight of biological classification
Provedor de dados: 92
Autores: Ebach,Malte C.; Carvalho,Marcelo R. de; Nihei,Silvio S.
Saving our science from ourselves: the plight of biological classification. Biological classification ( nomenclature, taxonomy, and systematics) is being sold short. The desire for new technologies, faster and cheaper taxonomic descriptions, identifications, and revisions is symptomatic of a lack of appreciation and understanding of classification. The problem of gadget-driven science, a lack of best practice and the inability to accept classification as a descriptive and empirical science are discussed. The worst cases scenario is a future in which classifications are purely artificial and uninformative.

Sexual dimorphism in Diabrotica speciosa and Diabrotica viridula (Coleoptera: Chrysomelidae)
Provedor de dados: 92
Autores: De Carli,Mayara; Rech,Caroline; Bento,José Maurício Simões; Nardi,Cristiane.
ABSTRACT Diabrotica speciosa (Germar) and Diabrotica viridula F. (Coleoptera: Chrysomelidae) are the two most abundant species of the genus in South America, and belong to the fucata and virgifera groups, respectively. Here, we characterize the dimorphism of the setae present on the basitarsi of males and females of these species. Dimorphism was confirmed in both species, and it was related to the presence of adhesive setae exclusively in males, which possess these structures on the basal tarsomeres of the pro- and mesothoracic legs.

This study aimed to characterize mango plants from cv. Imbú, widely used as rootstock in the Zona da Mata region, State of Minas Gerais (MG), Brazil. Though fruits of this cultivar do not present desirable commercial characteristics, this study allowed us to characterize part of plant morphology and fill a gap in the literature, providing subsidies for future investigations. For such, 'Imbú' plants (˜ 4-years old) from the collection of the Universidade Federal de Viçosa, located in Viçosa -MG were evaluated. The descriptors were: (i) leaf blade division;(ii) leaf composition;...

Phytobia (Diptera: Agromyzidae) from Brazil: new species, new record and a key to the Neotropical species
Provedor de dados: 103
Autores: Sousa,Viviane Rodrigues de; Couri,Márcia Souto.
ABSTRACT Phytobia Lioy, 1864 flies occur in all continents. There are four recorded species of these flies in Brazil, but recent expeditions at unexplored areas in the country have revealed that the genus is far more diverse than previously known. Based on material collected in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia (as part of the SISBIOTA Diptera Project), we describe fourteen new species of Phytobia. Additionally, we redescribe P. kallima (Frost), previously recorded only from Panama, and provide a key to the 32 resulting Neotropical species. All descriptions include details and illustrations of the male and female terminalia. The speciemens are deposited in the collections of Museu de Zoologia, Universidade de São Paulo (São Paulo,...

Provedor de dados: 103
Autores: Miglio,Laura T.; Lucas,Sylvia M.; Bonaldo,Alexandre B.
The type species of the Neotropical Actinopus, A. tarsalis Perty, 1833, is redescribed based on material from the type locality, the state of Piauí, Brazil. The species appears to be restricted to northeastern Brazil and is newly recorded from the state of Sergipe. An old record from the state of Rio Grande do Sul is rejected. Actinopus tarsalis differs from other species of the genus by details of the male copulatory bulb: tegular apophysis absent, robust embolar base, inserted basally at a right angle (90°); embolar apices apex flattened and expanded, arrow-shaped in dorsal view.

Autores: Klećkowska-Nawrot,Joanna; Nowaczyk,Renata; Gozdźiewska-Harłajczuk,Karolina; Szara,Tomasz; Olbrych,Katarzyna.
ABSTRACT The macroscopic anatomy and the microscopic and ultrastructural features of the Harderian gland (HG), lacrimal gland (LG) and superficial gland of the third eyelid (SGTE) of the adult European bison are described. In addition, morphometric studies were conducted and were followed by statistical analysis of the results. Tissue sections were stained with hematoxylin and eosin, methyl green-pyronin Y, periodic acid-Schiff, Alcian blue pH 2.5, aldehyde fuchsin and Hale's dialysed iron. Analysis of the staining showed that the HG has a multilobular tubuloalveolar structure with mixed secretion. The LG and the SGTE have a multilobar tubuloacinar structure with serous secretion in the LG and mucoserous in the SGTE. The TEM study demonstrates that the...

A new record of giant squid Architeuthis sp. (Cephalopoda: Oegopsida) in Brazilian waters
Provedor de dados: 103
Autores: Martins,Rodrigo Silvestre; Perez,José Angel Alvarez.
A carcass of a giant squid Architeuthis sp. was found afloat off Southern Brazil (28°05'S, 45°35'W) on 29 August 1999. The specimen was a mature female of 116 cm mantle length and had arms incomplete and tentacles missing. The specimen was morphologically similar to those previously described for the Southwest Atlantic, but a few peculiarities were found on the shape of the fins, head and the cross-section and length of ventral arms. Spermatophores were found embedded within the skin of the left ventral arm, at around 60 cm from the mouth, and could be traced to the core of the arm, radiating nearly four centimeters from the point of entry. This was the third record of Architeuthis in Brazilian waters and the eighth in Southwest Atlantic when the specimen...

Setting the reference for the use of Chironomus sancticaroli (Diptera: Chironomidae) as bioindicator: Ontogenetic pattern of larval head structures
Provedor de dados: 103
Autores: Rebechi,Débora; Navarro-Silva,Mário Antônio.
Species of Chironomidae are widely used as bioindicators of water quality, since their larvae undergo morphological deformities when in contact with sediment contaminated with chemicals. In this work we endeavored to study the morphology of head structures (antennae, mandible, mentum, pecten epipharyngis, ventromental plate and premandible) throughout the development of the four larval instars of Chironomus sancticaroli Strixino &amp;amp; Strixino, 1981, which can be used in environmental impact analyses. Our results show that it is possible to differentiate among larval instars by doing a quantitative analysis on the number of striae on the ventromental plates. The six structures analyzed changed during larval ontogeny. These changes are part of the...

Geographical variation in the reproduction and sexual dimorphism of the Boddaert's tropical racer, Mastigodryas boddaerti (Serpentes: Colubridae)
Provedor de dados: 103
Autores: Siqueira,Débora M.; Nascimento,Loana P.; Montingelli,Giovanna G.; Santos-Costa,Maria Cristina dos.
We obtained data on time of sexual maturity, dimorphism, fecundity and on the reproductive cycle of Mastigodryas boddaerti (Sentzen, 1796) through the examination of 321 preserved specimens, of which 221 were collected in the Brazilian Amazon region and 100 in the Cerrado savannas of Central Brazil. The degree of sexual size dimorphism (snout-vent length, SVL) was significantly greater in the specimens from the Cerrado in comparison with those from the Amazon. Females had a significantly larger number of ventral scales, on average, whereas males had more sub-caudal scales. However, there was no intersexual difference in tail length or head width, although the heads of the males were significantly longer, which may reflect dietary differences. Breeding...

Taxonomic identification using geometric morphometric approach and limited data: an example using the upper molars of two sympatric species of Calomys (Cricetidae: Rodentia)
Provedor de dados: 103
Autores: Boroni,Natália Lima; Lobo,Leonardo Souza; Romano,Pedro Seyferth R.; Lessa,Gisele.
ABSTRACT The taxonomic identification of micromammals might be complicated when the study material is fragmented, as it is the case with pellets and fossil material. On the other hand, tooth morphology generally provides accurate information for species identification. Teeth preserve notably well, retaining their original morphology, unlike skulls and mandibles, which can get crushed or have missing parts. Here, we explored a geometric morphometrics approach (GM) to identify fragmented specimens of two sympatric Calomys Waterhouse, 1837 species - Calomys tener (Winge, 1888) and Calomys expulsus (Lund, 1841) - using the morphology of intact molars as the basis for identification. Furthermore, we included some specimens of uncertain taxonomic identification...

Morphological variations caused by fixation techniques may lead to taxonomic confusion in Laeonereis (Polychaeta: Nereididae)
Provedor de dados: 103
Autores: Oliveira,Verônica M.; Santos,Cinthya S. G.; Lana,Paulo C.; Camargo,Maurício G.
The nereidid polychaete Laeonereis acuta (Treadwell, 1923) is either considered to be a valid species, or a synonym of Laeonereis culveri (Webster, 1879). The species epithet, acuta, refers to the acuminate anterior region of the body followed by a widening that is visible up to the 10th setiger. The relative width of the anterior region of the body, however, has been reported in the taxonomic literature as variable for Laeonereis Hartman, 1945, a genus known from the eastern coast of North America to Patagonia (southern South America). To test whether variations in this character are real, or whether they correspond to an artifact, we analyzed morphological changes associated with different anesthesia and fixation techniques regularly used to prepare...

Leontopithecus is the largest genus of Callithrichidae, occupying isolated remnants of the Atlantic Forest in Brazil. The objective of this study was to investigate the ultrastructure of the dorsum of the tongue of golden-headed lion tamarins. Tongues of ten adult lion tamarins kept in captivity at the Center of Primatology of Rio de Janeiro (CPRJ-FEEMA) were analyzed under scanning electron microscopy. The three vallate papillae were distributed in a V shape, and each papilla was surrounded by a deep sulcus and an external pad; the medial papilla showed a round shape and the lateral one was elliptical. The filiform papillae were shaped as a crown or as finger-like papillae, and were distributed throughout the tongue, including the margins, except for the...

Ecological separation by ecomorphology and swimming performance between two congeneric fish species
Provedor de dados: 103
Autores: Souza,Rafael C. R.; Pompeu,Paulo S.
ABSTRACT The high diversity of freshwater fish species reflects a great morphological plasticity. Understanding the relationship between swimming capacity, morphology and habitat use may be important to predict the chances of finding a species at an anthropized environment. The swimming capacity and morphological aspects of two sympatric species of Characidium, and for which spatial segregation in different hydraulic habitats is known, were compared in this study. Twenty-one individuals of Characidium fasciatum Reinhardt, 1867 and 23 individuals of Characidium cf. zebra Eigenmann, 1909 were captured and used for the evaluation of the swimming capacity and ecomorphological attributes. The swimming capacity of each species was obtained by measuring critical...

Ceraeochrysa caligata (Banks, 1945) is one of the several species of Ceraeochrysa Adams, 1982 that occur in agroecosystems of the Neotropical region and show potential for use in biological control programs. However, little is known about its biology, partly because of the poor status of the systematics of this group. To help in the identification of C. caligata and to contribute with additional characters for future phylogenetic studies with the genus, here we characterize the variations in relation to the pattern of integument markings originally described for the adults and larvae and redescribe the three larval instars, including characters not considered in the original description, especially the number of setae in the tubercles and somatic segments....

ABSTRACT Carlos Botelho State Park (PECB) is a large remnant of Atlantic Forest in Southeastern Brazil, with more than 37,000 ha. As its bat fauna is still unknown, we performed the first bat survey on PECB, to provide data on the distribution, natural history and taxonomy of the species. Fieldwork was conducted monthly, from October 2016 to September 2017. Captures were made using ground-level mist-nets (39600 m2.h), canopy mist-nets (2017.5 m2.h) and searches for roosts (42 hours).We captured 412 bats from 34 species of Phyllostomidae, Molossidae and Vespertilionidae. A total of 11 species were captured only in ground-level mist-nets, five in canopy mist-nets, and seven in roosts. Dermanura cinerea Gervais, 1856, Eptesicus taddeii Miranda, Bernardi &amp;...

Autores: Nogueira,Marcelo R.; Gregorin,Renato; Peracchi,Adriano L.
The Caatinga-endemic nectar-feeding bat, Xeronycteris vieirai Gregorin &amp;amp; Ditchfield, 2005 was described based on four specimens. Since then, only two additional specimens have been reported in the literature. Examination of a new specimen that closely agrees with the original description but presents two additional upper premolars, led us to review the type series of this taxon. Our analysis provided support to the recognition of the new specimen as a X. vieirai with supernumerary teeth and revealed new diagnostic characters that can help in the field identification of this species. Xeronycteris vieirai presents tricolored dorsal fur, entirely naked forearm, connection of the base of the spear of the noseleaf with the upper limit of the horseshoe...

Provedor de dados: 103
Autores: Alves,Soraya Tatiana M.; Abrunhosa,Fernando A.; Lima,Jô de F.
The gross morphology of foregut was investigated and described in detail for four freshwater crab species: a pseudothelphusid, Fredius reflexifrons (Ortmann, 1897) and three trichodactylids - Sylviocarcinus pictus (H. Milne-Edwards, 1853), Valdivia serrata White, 1847, and Dilocarcinus septemdentatus (Herbst, 1783). In general, the gastric mills of freshwater crabs showed a similar degree of complexity in relation to other marine species of Anomura and Brachyura previously described in the literature. However, significant morphological differences were observed among the analyzed species, as in ossicle numbers, features and connection types. A total of 38 ossicles were described for S. pictus and V. serrata and 37 ossicles for D. septemdentatus and F....

Three subspecies are currently recognized: Penelope o. obscura Temminck, 1815, P. o. bridgesi Gray, 1860, and P. o. bronzina Hellmayr, 1914. The limits between Penelope taxa are poorly understood since few studies have evaluated their differences in plumage, distribution and taxonomy. Based on 104 specimens deposited in ornithological collections we studied the variations in the plumage of P. obscura, including all characters that have been used to describe the included subspecies. Our results show that the plumage of these birds is extremely variable in southern and southeastern Brazil. Without any morphological and morphometric characters...

ABSTRACT The morphology of stomach ossicles of decapod crustaceans provides valuable information on their phylogeny and biology. We herein described ten new ossicles in the foreguts of two trichodactylid crabs, Sylviocarcinus pictus (H. Milne-Edwards, 1853) and Valdivia serrata White, 1847, in addition to previously described 38 ossicles, which are also recognized and listed. Five specimens each of S. pictus and V. serrata were selected for morphological analysis of gastric ossicles. The stomachs were obtained after removing the carapace, and they were fixed in 10% formalin for 24 hours. After this procedure, the stomachs were immersed in a solution of 10% Potassium Hydroxide (KOH) and heated to 100 °C during 60 minutes for tissue maceration. At this...

A new species of Tipuana (Auchenorrhyncha: Cicadellidae: Cicadellini) from the state of Amazonas, Brazil, with a key to males of the genus
Provedor de dados: 103
Autores: Cavichioli,Rodney Ramiro; Mejdalani,Gabriel.
A new species of Tipuana Melichar, 1926, T. similis sp. nov., is described and illustrated based on specimens from the state of Amazonas, northern Brazil. The new taxon is externally very similar to T. chirensis Young, 1977. It can be distinguished from the latter and from the other known species of the genus mainly by the aedeagus with a triangular, posteriorly directed projection between the basidorsal apodemes, and with shaft not expanded apically and bearing two sharp, short apical processes curved dorsally. Diagnostic features of the new species are also found in the paraphysis, which is symmetrical, expanded towards the apex and with a round apical excavation. A key to the species of Tipuana (males) is added.

Morphology and 18S rDNA gene sequence of Spirostomum minus and Spirostomum teres (Ciliophora: Heterotrichea) from Rio de Janeiro, Brazil
Provedor de dados: 103
Autores: Fernandes,Noemi M.; Silva Neto,Inácio D. da.
Species of Spirostomum Ehrenberg, 1838 are widely used as model organisms in ecological studies of environmental impacts and symbioses between ciliates and human pathogenic bacteria. However, the taxonomy of this genus is confused by the superficiality of the morphological descriptions of its included species, and the use of only a few characters for their differentiation. The present study provides details of total infraciliature, nuclear apparatus, morphometric data and 18S rDNA gene sequences of Spirostomum teres Claparède &amp;amp; Lachmann, 1858 and Spirostomum minus Roux, 1901, isolated from a sewage treatment plant and a freshwater lake in the city of Rio de Janeiro, Brazil, respectively. For the morphological descriptions of S. teres and S. minus,...

Autores: Aksit,Deniz; Mutaf,Beria Falakali; Balci,Ahmet.
The surface morphology of the ctenidia of Spondylus spinosus Schreibers, 1793 was studied with light and scanning electron microscopy for comparison with the gill structures of other bivalves. The demibranch of S. spinosus is heterorhabdic, with the principal filaments at the descending lamellae and ordinary filaments at the ascending lamellae. The gill lamellae have a prominent gauze-like structure at their distal part, with numerous groups of eight ordinary filaments. They bear ciliary arrays on their frontal surfaces and ostia at their latero-frontal surfaces. Frequent cirral plates form regular interfilamentary junctions. The description of the gill structure of S. spinosus presented here can be used to derive implications for the correlations among...

A new species of the sharpshooter genus Cardioscarta (Hemiptera: Cicadellidae) from Bolivia and Peru
Provedor de dados: 103
Autores: Cavichioli,Rodney Ramiro; Mejdalani,Gabriel.
ABSTRACT The South American sharpshooter genus Cardioscarta Melichar, 1932 comprises six species. In this paper we describe and illustrate C. splendida sp. nov. based on a specimen from Bolivia (male holotype deposited in DZUP). The new species can be recognized by the orange ground color with five transverse dark brown stripes on dorsum (one on crown and four on forewings), and by the aedeagus with two pairs of dorsal processes on the basal apodemes and a single process at the apex of the shaft. A female from Peru is tentatively assigned to the new species and is also described, since it has the same color pattern as the holotype. An updated key to males and females of all known species of the genus is also given.

The cephalic lateral line system of temperate perches (Perciformes: Percichthyidae) from Argentinean Patagonia
Provedor de dados: 103
Autores: Vega,Rocío M.; Viozzi,Gustavo P.
ABSTRACT The species of Percichthys (Percichthyidae) are endemic to southern South America. Some authors have pointed out that the genus includes four valid species, based on the morphology of the head, jaws, and fins. A phylogenetic analysis published by other authors suggests that three of them are morphotypes belonging to the same species, Percichthys trucha (Valenciennes, 1833). The aim of this study is to describe for the first time the morphology of the cephalic seismosensory system of Patagonian perches, and how these characters vary in the three morphotypes, in order to provide morphological elements to analyze the taxonomy of these fish species. Comparisons of the cephalic seismosensory system between juveniles and adults were also conducted....

Provedor de dados: 103
Autores: Couri,Márcia S.
Syllimnophora Speiser belongs to the Limnophorini tribe of the Coenosiinae subfamily. The genus can be distinguished from the others by the presence of cilia on the apical half of the dorsal surface of vein R1, combined with a strongly projected gena. In he Neotropical Region 28 species are known, three of them recorded from Ecuador - S. atrovittata (Stein), S. browni (Snyder) and S. suavis (Stein). The study of material from South America deposited at Muséum national d'Histoire naturelle (Paris) enabled the description of one species new to science - S. argentifrontata sp. nov. from San Miguel de Ibarra (Ecuador). A key to the identification of the four species is given.

Ophiomusium acuferum (Ophiolepididae) and Ophiomisidium pulchellum (Ophiuridae) (Ophiuroidea: Echinodermata), redescription based on the Brazilian specimens
Provedor de dados: 103
Autores: Borges,Michela; Campos,Lucia de Siqueira.
Ophiomusium (Ophiolepididae) and Ophiomisidium (Ophiuridae) are similar, but differ in features such as size of the adult, number of disc dorsal plates, length of the arms, shape of the first ventral arm plates and number of the tentacle. In this contribution, a large number of specimens of Ophiomusium acuferum Lyman, 1869 and Ophiomisidium pulchellum (Wyville Thomson, 1878) were sampled from southeastern and southern Brazilian at depths ranging from 46 to 1300 m. A close analysis has shown that specimens identified as Ophiomisidium pulchellum (C.W. Thomson, 1877) in several Brazilian museums are actually Ophiomusium acuferum Lyman, 1875. A total of 2330 individuals were examined: 2046 specimens of Ophiomusium acuferum ('Evaluation of the sustainable...

Provedor de dados: 103
Autores: Brito,Pedro; Targueta,Cíntia P.; Arruda,Walquíria; Santos,Fernanda; Bastos,Rogério.
ABSTRACT The anuran skin characteristically has different types of glands, most of which are microscopic and are spread throughout the skin. Some species have specialized regions where glands agglomerate, forming macroglands. The description of the external morphology of Ololygon centralis (Pombal &amp; Bastos, 1996) revealed the presence of an inguinal gland. Ololygon centralis is the only species of the genus that has a macrogland. The present study found these inguinal macroglands to be present only on male specimens, thus characterizing it as a sexually dimorphic skin gland. Microscopic analysis revealed that these glands are composed of many syncytial units involved by myoepithelial cells. The center of the syncytium is full of a proteinaceous...

Digestive and regenerative cells in the midgut of haploid and diploid males of the stingless bee Melipona quadrifasciata anthidioides (Hymenoptera: Apidae)
Provedor de dados: 103
Autores: Fernandes,Kenner M.; Martins,Gustavo F.; Serrão,José E.; Neves,Clóvis A.
In eusocial bees, workers and queens are diploid (2n), whereas males are haploid (n). However, in some species, including the stingless bee Melipona quadrifasciata anthidioides Lepeletier, 1836, 2n males arise from fertilized eggs resulting from the crossing between a queen and her brother. In the present study, we provide a comparative analysis of the digestive and regenerative cells in n and 2n pupae and adult males of M. quadrifasciata anthidioides. In n and 2n pupae and adult males, the number of regenerative cells/nest was similar. In n and 2n pupae, the mean number of digestive cells/midgut area was 2076 ± 0.60, whereas in adults it was 1234 ± 1.42 digestive cells/midgut area. The nuclear area of the digestive cells was also similar in both n and 2n...

ABSTRACT The purpose of this study was to examine the ovaries and the oviduct of juvenile females of the broad-snouted caiman, Caiman latirostris (Daudin, 1802), using light microscopy, histochemical and immunocytochemical techniques. The ovarian cortex was observed to contain groups of germinative cells and abundant previtellogenic follicles at different stages of development. In previtellogenic follicles, the oocyte was surrounded by a single cuboidal layer of granulosa cells, supported by the theca layer. The theca was formed by a concentric layer containing collage nous fibers, predominantly type I, and several smooth muscle fibers. The inner perivitelline layer appeared as a narrow basophilic region between the oocyte and the granulosa. The ovarian...

Provedor de dados: 103
Autores: Martins,Rodrigo Silvestre; Juanicó,Marcelo.
ABSTRACT The biology and ecology of southwestern Atlantic loliginid squids have been intensively researched in the last few decades, mostly off the Brazilian southern coast. However, information gathered by scientific research cruisers, either past or recent, is limited. Three species of loliginid squids - the warm-tempered Doryteuthis sanpaulensis (Brakoniecki, 1984), plus the tropical D. pleii (Blainville, 1823) and Lolliguncula brevis (Blainville, 1823) - were sampled along 16 degrees of latitude on the southwestern Atlantic (22-38°S). The samples were obtained mostly from oceanographic surveys, but also included squids caught by commercial fisheries, and a few specimens from museum collections. Squid response to abiotic variables, morphological...

Autores: Gallo,Sarita Bonagurio; Siqueira,Edson Ramos de; Delgado,Eduardo Francisquine; Silva,Maeli Dal Pai; Rosa,Gilberto Teixeira da.
The study verified the influence of different nutritional levels of the dams, before parturition, the weaning age of the lambs and the finishing system on lamb muscle fiber morphology and meat quality. Ile-de-France × Bergamacia crossbred dams grazing on natural grassland were divided into two groups: 1) nutritional supplement 30 days before the parturition (SUPL), and 2) no nutritional supplement (NS). These groups were further subdivided by weaning age of the lambs, which corresponded to either 45 or 60 days. The weaned lambs from each of the previous groups were also divided into different finishing systems: confined and fed a complete diet (CD), confined and fed hay (H) and kept on grassland (P). The lambs were slaughtered at 30 kg live weight (CD and...

ABSTRACT In this study, we investigated the differentiation of five different chicken ecotypes - Center, North, South, West, and East - of Saudi Arabia using discriminate analysis. The analysis was based on nine important morphological and phenotypic traits: body color, beak color, earlobe color, eye color, shank color, comb color, comb type, comb size, and feather distribution. There was a strong significant relationship between the phenotype and effect of geographic height in terms of comb type and earlobe color in males as well as body, beak, eye, and shank color. In particular, the comb type and earlobe color differentiated the ecotypes of males. Among the females, the beak, earlobe, eye, shank color, and feather distribution had more differentiating...

Review and phylogeny of the genus Tillobroma Hull with the description of ten new species and its relation with the genus Hypenetes Loew (Diptera, Asilidae, Stenopogoninae)
Provedor de dados: 97
Autores: ARTIGAS,JORGE N.; LEWIS,PETER D.; PARRA,LUIS E.
This paper examines the status and geographic distribution of the genera Hypenetes Loew and Tillobroma Hull; the status of the latter was shifted to generic level by Artigas &amp;amp; Papavero 1991. The genus Clavator Philippi, which is preoccupied, becomes synonymous to Tillobroma Hull, this has been proposed by Artigas &amp;amp; Papavero (1991), and is confirmed here. Hypenetes and Tillobroma have a possible common Gondwanan origin of approximately 180 millions years ago. Even though the external characters barely allow separation between the two genera, the obvious differences in spermathecae structures permit the inference of other internal differences and reinforce the independent status of the genera. This conclusion is also supported by 180 million...

Several compensatory mechanisms in pastures do not allow optimisation of responses from the processes of herbage production and utilisation. Compensation due to tiller size/density relationships is one of these mechanisms. This experiment evaluated this process for Coastcross bermudagrass and compared the responses to those reported for temperate forages. Treatments were "steady state" sward surface heights of 5, 10, 15, and 20 cm that were maintained from August, 1998, through July, 1999 by sheep grazing. The experimental design was a randomised complete block, replicated four times. Pasture responses were evaluated on four separate dates (15/12/1998, 25/01/1999, 07/04/1999 and 04/07/1999) with respect to: tiller population density, tiller weight, leaf...

The early stages of the tropical reef lobster Enoplometopus antillensis Lütken, 1865 were described and illustrated in detail from specimens reared in the laboratory. Ovigerous females were captured in their habitat, at a depth of about 15 meters and transported to the laboratory. The larvae were reared in a recirculation water tank for approximately 15 days and then transferred to four 10 liters aquariums. The larvae were fed on Artemia sp. nauplii. Microalgae Dunaliella viridis was added daily to the culture. The larvae moulted seven times progressing through the zoea VIII. Megalopa stage was not achieved. The intermoulting period of each stage averaged from eight to 12 days. Morphological comparisons with previous reports are briefly discussed.

A study has been made on the geographical distribution and comparative external and cranial morphological analysis of Artibeus lituratus Olfers, 1818 and Artibeus fimbriatus Gray, 1838 (Chiroptera, Phyllostomidae) in the state of Rio Grande do Sul, Brazil. A. lituratus and A. fimbriatus were found to be sympatric in the state north to the "Planície Costeira", in the "Depressão Central", in the hillsides of "Serra Geral", and in the northern region of the state, areas previously covered by forests. The southernmost point for Artibeus Leach, 1821 distribution is 30º South, and A. lituratus and A. fimbriatus are the two species found more to the south. The two species studied do not show sexual dimorphism as to external characteristics. Cranial measurements...

This Study Concerns the morphological changes of the testes of "curimbatá", Prochilodus scrofa (Steindachner, 1881) at the beginning of sperm production, before and after the hormonal injections. We examined 25 three year old males that were reared in tanks at the Experimental Fish and Frog Culturing Station of Pindamonhangaba of the Fisheries Institute of São Paulo. The testes were sampled at the start of sperm production, after the first hormone injection (5 IU/g for weight of hCG), and 14 days before and after a second injection. Testicle fragments of these specimens were fixed and embedded in historesin. At the beginning of sperm production, the milky-white gonad showed consistem superficial vascularization, exceeding thick sperm under light pressure....

Provedor de dados: 104
Autores: Buys,Sandor C.
The last instar larva of Tachysphex inconspicuus (Kirby, 1890) is described and illustrated. Minute spines on the anterior dorsal annulets of abdominal segments and different types of setae on prothorax and mesothorax are remarkable features observed in the larva of T. inconspicuus which were not reported in previously descriptions of larvae of the genus. Distribution of spines and sensilla on the epipharynx and distribution of setae on head and body seem also useful to distinguish Tachysphex larvae.

Morphology of the quitinized structures related to the spermatheca of Muscidae (Insecta, Diptera)
Provedor de dados: 104
Autores: Couri,Márcia Souto.
Little is known about the morphology of the quitinized structures related to the spermatheca of Muscidae (Diptera). Most papers illustrate only the spermatheca, which shape has little systematic significance when analyzed as a separate character. The analysis of these structures in 16 Muscidae species, made it possible to clarify and understand some characters, which can be used in further phylogenetic analysis. The species selected to this study belong to different sub-families: Muscinae, Muscini: Biopyrellia bipuncta (Wiedemann, 1830); Musca domestica Linnaeus, 1758; Azeliinae, Reinwardtini: Philornis univitattus Dodge, 1968; Cyrtoneurininae: Charadrella malacophaga Lopes, 1938; Cyrtoneurina polystigma (Wulp, 1896); Neomuscina neosimilis Snyder, 1949;...

A new Brazilian Calomys Waterhouse, 1837 species is described based on morphologic and karyologic data. This species is endemic to the Cerrado of Central Brazil and allopatric with all other species of the genus Calomys. Its chromosome complement (2n = 46, AN = 66) is different from those described in other Calomys species. Morphometric analysis significantly distinguished this new species from other Calomys of the Brazilian fauna like C. callosus (Renger, 1830), C. expulsus (Lund, 1841) and C. tener (Winge, 1887) and placed it among the large-sized Calomys.

Reproductive apparatus and gametogenesis of Lophiosilurus alexandri Steindachner (Pisces, Teleostei, Siluriformes)
Provedor de dados: 104
Autores: Barros,Marcelo D. M.; Guimarães-Cruz,Rodrigo J.; Veloso-Júnior,Vanderlei C.; Santos,José E. dos.
The gonad morphology and gametogenesis of Lophiosilurus alexandri Steindachner, 1877 from Santo Antônio river (Minas Gerais, Brazil) were studied through anatomical and histological techniques. Examination of the testis revealed that they were paired, fringed organs with two distinct regions: cranial spermatogenic and caudal spermatogenic and secretory.

Provedor de dados: 104
Autores: Donatti,Lucélia; Fanta,Edith.
The retina of Metynnis roosevelti Eigenmann, 1915, a very active freshwater fish, was investigated by light and electron microscopy and was found to have a complex neuronal structure that allows rapid responses of visual stimuli. Retina photoreceptors are double cones, single long cones, single short cones and rods. Cone inner segments are arranged as mosaics. The outer nuclear layer contains small nuclei of twin cones, long and wide nuclei of long single cones, spherical large nuclei of short cones, and small dense nuclei of rods. Horizontal, amacrine, bipolar and ganglion neurones are responsible for connections and integration between photoreceptor cells and afferent neurones. The pigmented epithelium comprises a single layer of cylindrical cells each...

Provedor de dados: 36
Autores: FLORES,Andréia Silva; COSTA,Eduardo de Souza; DIAS,Germana Bueno.
ABSTRACT Comparative studies on the structure of foliar anatomy in four species of Rhynchosia from Roraima state (northern Brazilian Amazon) were carried out to identify additional morphological characters to support the definition of the systematic boundaries among the species. Fully expanded leaves, including the petioles, were collected from the upper nodes of a plant’s stem. Anatomical characters were observed in cross-sections of the middle portion of leaflets and petiole segments. Presence and distribution of glandular trichomes, continuity of sclerenchyma around the vascular bundles in leaflet blades and the conformation of the area between the two ridges of petioles were important characters to distinguish among the species of Rhynchosia. For the...

Previous study on the resistance of larvae of Sesarma curacaoense submitted to starvation has revealed a facultative lecithotrophy during zoeal stages, but megalopa and first juvenile stages are exclusively feeding stages. In the present study, the gross morphology and fine structure of the foregut of S. curacaoense were investigated during larval, megalopa and first juvenile stages. The foregut of the zoea I show specific setae and a filter press apparently functional. The foregut undergoes changes in the zoea II (last larval stage) with increment of setae number, mainly on the cardiopyloric valve and complexity of the filter press. After metamorphosis to megalopa stage the foregut become rather complex, with a gastric mill supporting a medial and two...

Phlebotomine sand flies are insects of medical importance. Species in the Neotropical region are highly diverse. Some of these species are considered cryptic species because of their morphological similarity between adult females of different species make identification especially difficult. The aim of this study was to analyze and describe the armature in the genital atrium (AGA) of some adult female sand flies, in order to discover new taxonomic characters that make it possible to distinguish between species that would otherwise be treated as cryptic by analysis of the AGA. The AGA of 16 Phlebotomine sand fly species are described. Distinct differences were found in relation to the shape and size of the armature, the presence or absence of spines on the...

ABSTRACT During a survey conducted in the Lajeado Reservoir of the Tocantins River, in the state of Tocantins, Brazil, dactylogyrids were recovered from the gills of Pimelodina flavipinnis. Initial morphological analysis showed these dactylogyrids shared aspects of character with species of Demidospermus, with affinity to Demidospermus pinirampi, despite exhibiting differences with the original description by Kritsky et al. (1987) regarding the vagina, the base of the male copulatory organ and the shape and length of the bars. The analysis of the holotypes of D. pinirampi and its most morphologically close species, Demidospermus luckyi, revealed that these dactylogyrids were indeed D. pinirampi. This study therefore reports a new host and locality of...

Autores: Abrunhosa,Fernando; Melo,Marlon; Lima,Jô de Farias; Abrunhosa,Jacqueline.
In this study, the gross morphology of the mouthparts and foregut of the ghost shrimp Lepidophthalmus siriboia were investigated from larvae and postlarvae reared in the laboratory. The mouthparts (maxillae and maxillipeds) of the zoeae have a reduced number of setae and spines (or is absent in some individuals), and the foregut, under developed, have few minute setae in the cardiac and pyloric chambers. In contrast, after the metamorphosis into megalopa stage, all feeding appendages have many setae and, the foregut shows a well-developed gastric mill with strong lateral teeth. In the juvenile stage occurs an increase of setae and spines in the mouthparts and the foregut becomes more specialized. These observations strongly suggest that a lecithotrophic...

Provedor de dados: 39
Autores: Moreira,Giselle Lopes; Cavalcanti,Taciana Barbosa; Mendonça,Cláudia Barbieri Ferreira; Gonçalves-Esteves,Vânia.
Abstract There are nine species of the plant genus Verbesina in Brazil, which are distributed in the Northeast, Center-West, Southeast and South regions of the country. The objective of the present study was to describe the pollinic morphology of eight of these species to better characterize them and evaluate potential species-level taxonomic characters. Acetolysed pollen material was measured within seven days under light microscopy, while non-acetolyzsed pollen grains were used for scanning electronic microscopy. The pollen grains were found to be oblate-spheroidal, medium-sized, isopolar, monads that are 3-colporate with a subtriangular amb, a small polar area, a long colpus, a lalongate endoaperture, a caveate exine and an echinate sexine. Although the...

ABSTRACT Thailand and other tropical regions have high fungal diversity. Our investigation and examination of microfungi on palms (Arecaceae) revealed two new ascomycetous species of Fissuroma. Fissuroma arengae and F. wallichiae spp. nov. are introduced using morphological and phylogenetic evidence. The novel species have coriaceous ascomata, cylindrical-clavate asci and ascospores with a distinct and thin mucilaginous sheath. Fissuroma arengae is similar to F. wallichiae but can be distinguished by minor morphology, host substrate and gene base-pair differences. Phylogenetic analyses of combined LSU, ITS, SSU, tef1-α and rpb2 sequence data showed that these strains grouped within Fissuroma, further confirming this genus as monophyletic. The two new...

Autores: Barros,Thais Cury De; Marinho,Cristina Ribeiro; Pedersoli,Giseli Donizete; Paulino,Juliana Vilella; Teixeira,Simone Pádua.
ABSTRACT Floral secretory structures are usually associated with the attraction of pollinators, but may also play an important role in the mechanisms of plant protection. This study aimed to show the diversity of secretory structures present in the developing flowers of 15 legume species belonging to different clades and to associate them with functions other than the pollinator attraction. Buds, flowers and developing axis of inflorescence were processed for surface, histological, and ultrastructural analyses. The species investigated displayed a wide diversity of secretory structures in developing flowers such as phenolic cells and/or tissues, mucilaginous cells, secretory cavities, secretory trichomes and colleters. Each type of secretory structure...

Provedor de dados: 39
Autores: Silva-e-Costa,Juliana da Costa; Luizi-Ponzo,Andrea Pereira.
ABSTRACT Plagiochilaceae is a family of leafy liverworts that are distributed worldwide. It is of great importance due to its taxonomic and ecological implications among bryophytes. Most species of the family belong to the genus Plagiochila, but there is no consensus regarding its infrageneric circumscription. There have been few palynological studies involving Plagiochilaceae and Plagiochila. Here, we describe the spore morphology of seventeen species of Plagiochila and discuss the taxonomic value of palynological characters for these taxa. The spores were processed by standard palynological techniques and analyzed using light and electron microscopy. The spores were found to be apolar, spheroidal, released monads that vary in size from 13µm to 58µm...

ABSTRACT Salinity is an important abiotic factor since it is responsible for the local and/or regional distribution of algae. In coastal regions, salinity changes with prevailing winds, precipitation and tide, and particularly in extreme intertidal conditions. Acanthophora spicifera is a red seaweed that occurs in the supratidal region in which changes in abiotic conditions occur frequently. This study evaluated the effects of salinity on the metabolism and morphology of A. spicifera. Algae were acclimatized under culture conditions with sterilized seawater for seven days. Experiments used different salinities (15 to 50 psu) for seven days, followed by metabolic analyses. This study demonstrates that extreme salinities affect physiological parameters of A....

Otoliths were characterized with smooth margins for both species but with different shapes: oblong for C. spixii and oval for G. genidens. The morphological differentiation between the two species is in the anterior region: rounded for C. spixii and pointed for G. genidens. The t-test results for otolith measurements were: length (t value = -2.88; p = 0.0042), height (t value = -6.87; p &amp;lt; 0.000001), anterior angle (t value= 9.84; p = 0.000001) and posterior angle (t value =0.41; p...

This paper verified possible alterations caused by a genotype II Toxoplasma gondii strain with respect to the total number and morphometry of the myenteric neurons in the terminal ileum and descending colon of rats. Eight rats were divided into two groups: control (n = 4) and experimental (n = 4). This group was inoculated orally with 20 tissue cysts of T. gondii from a genotype II strain (ME-49). Whole mounted from the terminal ileum and the descending colon were stained with Giemsa. There was not any neuronal loss on both organs. The neurons became hypertrophied in the terminal ileum, whereas morphometric alterations were not observed for the neurons in the descending colon.

Pyrostegia venusta (the orange trumpet or commoly called cipó-de-São-João in Brazil), a medicinal plant that grows with other plants, has an ecological importance due to the presence of nectaries on the leaves. The aim of this work was to study structural and histochemical aspects and the distribution of extrafloral nectaries (ENFs) in P. venusta leaves. Young leaves were collected, fixed and processed by usual techniques, and studied under light microscopy and scanning electron microscopy. Analyses showed that the extrafloral nectaries are dispersed throughout the leaf, with concentrations mainly in the basal third section. Nectaries lie in epidermal depressions and can be found in abaxial and adaxial leaf blades. Their morphology may be characterized...

Autores: Oliveira, Naila Francis Paulo de; UNICAMP; Genari, Selma Candelária; UNICAMP; Dolder, Heidi; UNICAMP.
Many chemotherapeutic agents with a potential against solid tumors or leukemia can cause lymphopenia. Tamoxifen (TAM) is a synthetic non-steroidal anti-estrogen drug employed in female breast cancer treatment. The present study investigated the capacity of TAM to induce cell death in human lymphocytes cultivated in vitro. Lymphocytes were obtained from young (25-30 years; n = 3) and elderly women (58-77 years; n = 3) and cultivated for 24 or 48h, with or without TAM (20 &amp;micro;M). After the culture, cell viability, immunocytochemical response and ultrastructure were evaluated. TAM affected lymphocytes in a time- dependent manner, and cells obtained from elderly women were the most sensitive to TAM. Immunocytochemical analysis evidenced higher frequency...

Abstract Herbicides can impact non-target metabolic pathways in natural enemies and lead to the reduction of these populations in the field. Behavioral characteristics, morphology and histology of reproductive structures and reproduction of females of Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) were evaluated under the effect of the herbicides atrazine, nicosulfuron and the mixture of both. The number of mature oocytes per ovary was lower in females exposed to the herbicides atrazine, nicosulfuron and the mixture of both. Herbicides did not affect the longevity and mortality of P. nigrispinus, therefore, they are selective for this predator. On the other hand, herbicides can cause sublethal effects by affecting the reproduction of predators.

Autores: Mazali,Italo O.; Alves,Oswaldo L.
High fidelity calcium carbonate and hydroxyapatite (bio) inorganic replicas of the fibrous network of the dried fruit of Luffa cylindrica are described, utilizing a facile synthetic route. The loofa sponge is a highly complex macroscopic architectural template, an inexpensive and sustainable resource. In the context of the morphosynthesis, the capability of replication of the loofa sponge opens the possibility of the use of biodiversity in obtaining new materials. We would like to emphasize that the template proposed in this paper, makes possible the preparation of inorganic replicas with a very desirable size, on the centimeter scale. This fact is innovative with respect to inorganic replicas described in the literature, which predominate at the...

In this study, the hypolipidemic effect of exopolysaccharides (EPS) fromPleurotus geesteranus 5# fermenting liquor by the optimal culture conditions in a 5-L stirred-tank reactor was investigated. The hypolipidemic effect of the polysaccharide, investigated in streptozotocin induced diabetic mice, decreased plasma glucose, total cholesterol and triacylglycerol concentrations by 17.1 %, 18.8 % and 12.0 %, respectively. The results of the present investigation strongly demonstrate the potential of this polysaccharide to prevent hyperglycemia in the experimental animals. Under optimal culture conditions, the maximum concentrations of mycelial and EPS were 22.63 g/L after 7 d cultivation and 11.09 g/L after 10 d, respectively. Furthermore, the morphological...

Morphological and morphometric variability of the squid Lolliguncula brevis (Mollusca: Cephalopoda) in Brazilian waters: evidence for two species in the western atlantic?
Provedor de dados: 42
Autores: Zaleski,Tânia; Perez,José A. Angel; Gandara-Martins,Ana luiza.
Morphological and morphometric variability of the small-sized coastal squid Lolliguncula brevis was assessed along the largest part of its latitudinal range in the southern hemisphere, off the Brazilian coast (8º S - 27º S). A general homogeneity in form was found throughout the entire latitudinal range. In terms of body proportions, no latitudinal gradients were evident, but a few local "morphotypes" could be distinguished. The distinctive egg mass morphology, and size and form features, including a hectocotylus 20-40% longer than the opposing ventral arm and the presence of suckers on the buccal membrane, indicated that Lolliguncula from northern and southern hemispheres might comprise two different taxa.

Autores: ARAÚJO,OLÍVIA G.S.; HADDAD,CÉLIO F.B.; SILVA,HÉLIO R. DA; PUGENER,LOURDES A.
ABSTRACT Pipa is a Neotropical genus of frogs that dwell in freshwater environments. It includes four species that lack free-swimming larvae (P. aspera, P. arrabali, P. pipa, and P. snethlageae) and three with tadpoles (P. carvalhoi, P. myersi, and P. parva). Developmental tables such as the one proposed by Nieuwkoop and Faber might be useful for Pipa species with tadpoles. However, for the other Pipa species, to determine stages by this table or by any of the tables already prepared for frogs without tadpoles (e.g., Crinia nimbus, Eleutherodactylus coqui, and Oreobates barituensis) is impossible. By using embryonic, juvenile, and subadult specimens, we generated a staging table for P. arrabali, from the moment limb buds were first observed until birth,...

Autores: Alencar,Nara L.M.; Innecco,Renato; Gomes-Filho,Enéas; Gallão,Maria Izabel; Alvarez-Pizarro,Juan C.; Prisco,José T.; Oliveira,Alexandre B. De.
Cereus jamacaru, a Cactaceae found throughout northeast Brazil, is widely used as cattle food and as an ornamental and medicinal plant. However, there has been little information about the physiological and biochemical aspects involved in its germination. The aim of this study was to investigate its reserve mobilization during germination and early seedling growth. For this, C. jamacaru seeds were germinated in a growth chamber and collected at 0, 2, 4, 5, 6, 8 and 12 days after imbibition for morphological and biochemical analyses. Dry seeds had wrinkled seed coats and large, curved embryos. Lipids were the most abundant reserve, comprising approximately 55% and 65% of the dry mass for cotyledons and the hypocotylradicle axis, respectively. Soluble sugars...

Autores: SOUZA NETO,JOSÉ RICARDO N. DE; BRANCO,ÉRIKA; GIESE,ELANE G.; LIMA,ANA RITA DE.
ABSTRACT The wall of the diaphragm can be affected by congenital or acquired alterations which allow the passage of viscera between the abdominal and chest cavities, allowing the formation of a diaphragmatic hernia. We characterized morphology and performed biometrics of the diaphragm in the common squirrel monkey Saimiri sciureus. After fixation, muscle fragments were collected and processed for optical microscopy. In this species the diaphragm muscle is attached to the lung by phrenopericardial ligament. It is also connected to the liver via the coronary and falciform ligaments. The muscle is composed of three segments in total: 1) sternal; 2) costal, and 3) a segment consisting of right and left diaphragmatic pillars. The anatomical structures analyzed...

Carajathemis simone, new genus and species from Brazil (Odonata: Libellulidae)
Provedor de dados: 42
Autores: Machado,Angelo B.M.
Carajathemis simone n. gen., n.sp. from the state of Pará, Brazil, is described and illustrated based on 22 specimens collected in a "canga" (laterite) lake within the forest at the Flona de Carajás, Parauapebas Municipality. The new libellulid genus fits in the subfamily Sympetrinae and the male keys out to Erythemis in Garrison et al. (2006). The new taxon has a combination of characters that makes it different from all genera of Sympetrinae including Erythemis. The species is remarkable by its large size, pleural striping and especially by the complex and strongly dimorphic leg armature. It seems to be restricted to shallow, rainfall-dependent, iron-rich lakes.

Several publications have contributed to improve the stratigraphy of the Paraíba Basin in northeastern Brazil. However, the characterization and distribution of sedimentary units in onshore areas of this basin are still incomplete, despite their significance for reconstructing the tectono-sedimentary evolution of the South American passive margin. This work provides new information to differentiate among lithologically similar strata, otherwise entirely unrelated in time. This approach included morphological, sedimentological and stratigraphic descriptions based on surface and sub-surface data integrated with remote sensing, optically stimulated luminescence dating, U+Th/He dating of weathered goethite, and heavy mineral analysis. Based on this study, it...

The monotypic Brazilian genus Diacrodon is a synonym of Borreria (Spermacoceae, Rubiaceae): morphological and molecular evidences
Provedor de dados: 42
Autores: MIGUEL,LAILA M.; SOBRADO,SANDRA V.; JANSSENS,STEVEN; DESSEIN,STEVEN; CABRAL,ELSA L.
ABSTRACT Diacrodon is a monotypic genus of the tribe Spermacoceae (Rubiaceae), endemic to northeastern Brazil. Diacrodon compressus is frequently misidentified with a two lobed calyx species of Borreria, B. verticillata. Traditionally, in Spermacoceae the fruit type was considered a diagnostic character among the genera. In this sense, D. compressus presents a strongly compressed, one seeded and indehiscent fruit (vs. globose, two seeded and dehiscent fruit in B. verticillata). In this work, we address two objectives: evaluate the systematic position and determine the identity of Diacrodon in respect to other taxa. Molecular analyses using ITS and ETS indicate that D. compressus is strongly related to other species of Borreria. The morphological results...

The representatives of the genus Hylesia Hübner, [1820] are significant among the medically important Lepidoptera. Adult females use abdominal setae to wrap and protect the eggs that remain for months in nature. These setae, in contact with human skin, may cause allergic reactions including swelling, itching and local erythema, known as lepidopterism. The morphology of the abdominal scales and setae from the female H. oratex Dyar, 1913 is herein described and aspects related to their medical significance are discussed. Portions of each abdominal segment were examined through a scanning electron microscope. Two types of scales without medical importance, and two types of setae with medical importance, classified as "true setae" and "modified setae" were...

Autores: AZEVEDO,ÉRICA F.S.; SILVA,DANIELA R. COSTA E; NATIVIDADE,TAMIRES V.S.; GIESE,ELANE G.; LIMA,ANA RITA DE; SOARES,PAOLA C.; BRANCO,ÉRIKA.
ABSTRACT The wall of the diaphragm can be affected by changes caused by physical trauma, allowing the passage of viscera between the abdominal cavity and thoracic cavity, thus reducing the space for pulmonary expansion, leading to the formation of hernia and possible death. Thus, we aimed to characterize, size and determine the topography of the diaphragmatic muscle in the Southern Tamandua, since clinical and surgical activities in wild animals have become a reality more and more present in veterinary medicine. We used six adult animals, x-rayed and dissected, followed by collection of fragments of muscular portions for histological analysis. Initially we observed that the animals presented 17 thoracic vertebrae, 3 lumbar vertebrae and 5 sacral vertebrae....

Autores: GONZÁLEZ,CYNTHYA E.; GÓMEZ,VALERIA I.; HAMANN,MONIKA I.
Abstract: Aplectana hylambatis is a nematode with a wide geographic distribution and low host specificity. In spite of numerous reports, until this moment, the morphological variations between different hosts and localities have not been studied. We studied 401 specimens collected from five host species from seven localities in Argentina, and examined the following morphological characters: mamelon-like cuticular protuberances anterior to the vulva, structure of the gubernaculum and the spicules, number and arrangement of caudal papillae, and the measurements of twelve characters in females and eleven characters in males. The results showed that mamelon-like protuberances and caudal papillae varied in number and arrangement between different hosts and...

Autores: GAUDIOSO,PABLO J.; DÍAZ,M. MÓNICA; BARQUEZ,RUBÉN M.
ABSTRACT Here we present detailed descriptions and comparisons of the axial skeleton of seven species of bats belonging to five subfamilies of Phyllostomidae of different trophic guilds. The material examined consisted of 34 complete skeletons of seven species. For five of the studied species, previous descriptions have not been conducted, and for the vampires only limited information is available, so that descriptions for these species are here completed. The axial skeleton has characters that allow grouping of the species phylogenetically of the same subfamily and by feeding habits. At the same time, there are characters that associate species from different subfamilies with different types of diet or ways to obtain food.

The knowledge on ovigeny in parasitoids is important for basic studies on physiology and applied biological control. The ovigeny pattern and type of ovariole of the parasitoid Palmistichus elaeisis Delvare &amp;amp; LaSalle (Hymenoptera: Eulophidae) were studied in newly-emerged females at seven, 14, 24 and 48 h intervals after their emergence from Tenebrio molitor L. pupae (Coleoptera: Tenebrionidae). Females of P. elaeisis presented ovaries composed by four ovarioles of the meroistic polytrophic type. The yolk accumulation and chorionogenesis in P. elaeisis were concluded 24 h after the female emergence. The 48 h-old females show a high quantity of egg ready for oviposition. These findings can help to improve the mass production of P. elaeisis and the...

Autores: Paschoal,A.F.L.; Santos,J.T.; Mellagi,A.P.G.; Bernardi,M.L.; Wentz,I.; Bortolozzo,F.P.
ABSTRACT This study aimed to evaluate the use of some testicular traits to identify boars with low sperm morphological quality. The consistency (scores from 1 to 5), tone with tonometry (mm), parenchyma echogenicity and heterogeneity with ultrasound (pixel) were assessed in 402 mature boars (18.5 months on average). Sperm abnormality thresholds (≤ 25% of total sperm abnormalities, ≤ 5% of heads, acrosome, neck or midpiece defects, ≤ 10% tail defects, and 15% cytoplasmic droplets) were used to classify boars as approved or disapproved. Three classes of testicular traits were formed (extremely low and high values, approximately 15% each, were kept in separated classes). When the traits were individually evaluated, fewer boars were approved if the...

The aim of the present study was analyze, by histological and morphometrical studies, mandibular glands of Melipona bicolor queens collected from monogynic and polygynic colonies and compare their level of development. The results showed that the glands of physogastric queens from monogynic colony present a higher level of activity in relation to the queens of polygynic colonies; this is explained by the fact that just a unique queen controls the monogynic colony. In the polygynic colonies, the queens may divide such control to each other.

Effects of shape variations on the energy metabolism of the sand cricket Gryllus firmus: a geometric morphometric analysis
Provedor de dados: 48
Autores: Nespolo,Roberto F; Sepúlveda,Roger D; Castañeda,Luis E; Roff,Derek A.
Respiration and energy metabolism are key processes in animals, which are severely constrained by the design of physical structures, such as respiratory structures. Insects have very particular respiratory systems, based on gas diffusion across tracheae. Since the efficiency of the tracheal respiratory system is highly dependent on body shape, the pattern of morphological variation during ontogeny could have important metabolic consequences. We studied this problem combining through-flow respirometry and geometric morphometrics in 88 nymphs of the sand cricket, Gryllus firmus. After measuring production in each individual, we took digital photographs and defined eight landmarks for geometric morphometric analysis. The analysis suggested that ontogenic...

A light- and electron microscopic study of primordial germ cells in the zebra fish (Danio rerio)
Provedor de dados: 48
Autores: Deniz Koç,Nazan; Yüce,Rikap.
In sexually reproducing organisms, primordial germ cells (PGCs) give rise to the cells of the germ line, the gametes. In many animals, PGCs are set apart from somatic cells early during embryogenesis. This study explores the origin of primordial germ cells (PGCs) of the zebra fish and examines their morphology during early development (1st day-15th day). PGCs were selectively stained by the alkaline phosphatase histochemical reaction and viewed by light and electron microscopy from the time they are first detectable in the yolk sac endoderm. PGCs occurred in the subendodermal space on the syncytial periblast; differing from the surrounding endodermal cells. Later the PGCs moved to between the blastoderm and yolk sac and transferred to the dorsal mesentery...

BACKGROUND: The epicuticular waxy layer of plant leaves enhances the extreme environmental stress tolerance. However, the relationship between waxy layer and saline tolerance was not established well. The epicuticular waxy layer of rice (Oryza sativa L.) was studied under the NaHCO3 stresses. In addition, strong saline tolerance Puccinellia tenuiflora was chosen for comparative studies. RESULTS: Scanning electron microscope (SEM) images showed that there were significant changes in waxy morphologies of the rice epicuticular surfaces, while no remarkable changes in those of P. tenuiflora epicuticular surfaces. The NaHCO3-induced morphological changes of the rice epicuticular surfaces appeared as enlarged silica cells, swollen corns-shapes and leaked salt...

This study was undertaken to determine the effects of varied salinity regimes on the morphological traits (plant height, number of leaves, number of flowers, fresh and dry weight) and major mineral composition of 13 selected purslane accessions. Most of the morphological traits measured were reduced at varied salinity levels (0.0, 8, 16, 24 and 32 dS m-1), but plant height was found to increase in Ac1 at 16 dS m-1 salinity, and Ac13 was the most affected accession. The highest reductions in the number of leaves and number of flowers were recorded in Ac13 at 32 dS m-1 salinity compared to the control. The highest fresh and dry weight reductions were noted in Ac8 and Ac6, respectively, at 32 dS m-1 salinity, whereas the highest increase in both fresh and dry...

Ultrastructural changes of erythrocytes in whole blood after exposure to prospective in silico-designed anticancer agents: a qualitative case study
Provedor de dados: 48
Autores: Repsold,Lisa; Mqoco,Thandi; Wolmarans,Elize; Nkandeu,Sandra; Theron,Joji; Piorkowski,Tomek; du Toit,Peet; van Papendorp,Dirk; Joubert,Annie Margaretha.
BACKGROUND: Novel, in silico-designed anticancer compounds were synthesized in our laboratory namely, 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10),15-tetraen-17-ol (ESE-15-ol) and 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10)16-tetraene (ESE-16). These compounds were designed to have improved bioavailability when compared to their source compound, 2-methoxyestradiol. This theoretically would be due to their increased binding affinity to carbonic anhydrase II, present in erythrocytes. Since the novel compounds under investigation are proposed to be transported within erythrocytes bound to carbonic anhydrase II, the morphological effect which they may exert on whole blood and erythrocytes is of great significance. A secondary outcome included revision of previously...

Autores: Visagie,Michelle Helen; Jaiswal,Seema Rummurat; Joubert,Anna Margaretha.
BACKGROUND: Computer-based technology is becoming increasingly essential in biological research where drug discovery programs start with the identification of suitable drug targets. 2-Methoxyestradiol (2ME2) is a 17ß-estradiol metabolite that induces apoptosis in various cancer cell lines including cervical cancer, breast cancer and multiple myeloma. Owing to 2ME2's poor in vivo bioavailability, our laboratory in silico-designed and subsequently synthesized a novel 2ME2 analogue, 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10),15-tetraen-17-ol (ESE-15-ol), using receptor- and ligand molecular modeling. In this study, the biological effects of ESE-15-ol (180 nM) and its parent molecule, 2ME2 (1 &amp;#956;M), were assessed on morphology and apoptosis induction in...

Autores: Coelho,Paula Nunes; Braghin,Louizi Souza Magalhães; Lansac-Tôha,Fabio Amodêo; Henry,Raoul.
Abstract: Testudinella is a taxon of Rotifera broadly distributed in Brazil. In a recent collection in marginal lakes connected to the Paranapanema River (São Paulo, Brazil), we found specimens of Testudinella mucronata and T. patina with concavities on their lorica. The objective of this study was to describe the concavities observed in individuals of both species and discuss their possible causes. Plankton samples were collected at two sampling stations, in the pelagic (PZ) and littoral (LZ) zones of the Panema and Coqueiral lakes; both of these lakes are ultra-oligotrophic and not polluted. For T. mucronata, 4% of individuals with concavities were found in the PZ of Coqueiral lake and 50% in the LZ of Panema lake. In T. patina, the proportion of...

DNA barcoding and traditional taxonomy unified through Integrative Taxonomy: a view that challenges the debate questioning both methodologies
Provedor de dados: 49
Autores: Pires,Amanda Ciprandi; Marinoni,Luciane.
The taxonomic crisis, emphasized in recent years, is marked by the lack of popularity (lack of interest in taxonomy) and financial incentives to study biodiversity. This situation, coupled with the issues involved with the necessity of knowing many yet undiscovered species, has meant that new technologies, including the use of DNA, have emerged to revitalize taxonomy. Part of the scientific community, however, has rejected the use of these innovative ideas. DNA barcoding has especially been the target of numerous criticisms regarding its application, as opposed to the use of morphology. This paper aims to highlight the inconsistency of the debate involving DNA versus morphology, since there is a proposal for the integration of traditional taxonomy and DNA...

Provedor de dados: 50
Autores: Correa Polo,Francisco; Eslava Eljaiek,Pedro; Martínez P.,Carlos; Narváez Barandica,Juan Carlos.
The dental morphology of J. pichardi and its relation to dietary habits is described for the first time. This mugilid inhabits the torrential rivers of short course in the Sierra Nevada de Santa Marta, that quickly lead into the Caribbean Sea. Joturus pichardi has heterodont dentition, with different forms that vary according to the tooth containing structure. The observed tooth structure is typical of omnivorous fishes, and consistent with the structure and composition of the diet analyzed. The latter was found dominated by mosses and aquatic macro invertebrates, mainly Chironomidae, a family of Diptera.

Fruiting material of Chenia lorentzii (Bryophyta, Pottiaceae) found in Argentina and an evaluation of the sporophyte taxonomic value in the genus Chenia
Provedor de dados: 51
Autores: Flores,Jorge R; Suárez,Guillermo M.
In the present contribution, the sporophyte of Chenia lorentzii is described in detail and microphotographs are provided. In addition, the role of sporophytic characters is discussed in a phylogenetic context. To accomplish this task, first, a phylogenetic analysis of a reduced dataset of Pottiaceae genera was carried out by using molecular data (nad5, rps4, 26S) and combined data (morphology and molecular markers). Then, gametophytic and sporophytic characters were mapped onto the molecular tree and their fit to the phylogeny was assessed on the basis of their extra steps and the number of diagnosed nodes. Results suggest that sporophytic characters should be treated with caution when nomenclatural generic changes are proposed.

The composition of the essentials oils of five species of Conyza Less from Argentina was determined by Gas Chromatography-Mass Spectrometer. This composition is associated to morphological and cytogenetic characters. The monoterpenes constitute more than 60% of the essential oils in C. blakei, C glandulitecta, C. sumatrensis var. sumatrensis and C. sumatrensis var. floribunda, in which limonene is the predominant compound. In C. bonariensis and C. primulaefolia the monoterpene content constitute less than the 40%. C. bonariensis presents only 13% limonene, while in C. primulaefolia it is absent. The similarity analysis of monoterpenes showed a relationship between the morphological and cytogenetic analysis, and the monoterpene content character seems to be...

Autores: Gradstein,S. Robbert; Reiner-Drehwald,M. Elena.
We describe the new liverwort species Cheilolejeunea schiavoneana M.E.Reiner &amp;amp; Gradst. from submontane rainforest in the Western Cordillera of Colombia. The new species is related to C. adnata (C. sect. Cheilolejeunea) but differs by larger plant, leaf and underleaf size, robust stems, a 5-6 cells wide ventral merophyte, abundance of microphyllous branches, and vegetative reproduction by caducous leaf lobes produced on flagelliform shoots. The latter feature is characteristic of the genus Rectolejeunea and its presence in Cheilolejeunea is apparently a case of parallel evolution. The discovery of C. schiavoneana adds a further endemic taxon to the rich flora of the Colombian Western Cordillera.

Autores: Rudnicki,Cácia Aparecida Mendes; Melo,Gisele Cristiane; Donatti,Lucélia; Kawall,Helena Gonçalves; Fanta,Edith.
Piaractus mesopotamicus is a freshwater native fish from rivers of the Paraná-Paraguay Basin and of the Pantanal region and has been used for repopulation programs in Brazil. Juvenile fishes were exposed to the sub-lethal dose of 1.08mg/L of the OP Azodrin®400 containing 0.43µL/L of the active principle monocrotophos for 96 h. A frequent pathology in the gills at all times of exposure was epithelial detachment, from minimal until 24 h of exposure, to intense after 48 h of contamination. Deformed pillar cells in the respiratory lamellae leading to irregular blood spaces and blood congestion, as well as hyperplasia and lamellar fusion were observed. These histopathologies suggested that 48 h after T0 was an important time when a reduction in the capability...

This work evaluated the effect of in vitro and in vivo treatment with ASA on the morphology of the red blood cells. Blood samples or Wistar rats were treated with ASA for one hour. Blood samples or animals treated with saline were used as control group. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of red blood cells were evaluated under optical microscopy. Data showed that the in vitro treatment for one hour with ASA at higher dose used significantly (p&lt;0.05) modified the perimeter/area ratio of the red blood cells. No morphological alterations were obtained with the in vivo treatment. ASA use at highest doses could interfere on shape of red blood cells.

Autores: Hahn,Norma Segatti; Cunha,Fabiane.
The aim of this work was to evaluate the relationship between diet and features of the trophic ecomorphology of Satanoperca pappaterra (Heckel, 1840) in an impacted environment. Samples were collected from March 2000 to February 2003 in Manso Reservoir, Cuiabá River, Mato Grosso State. Analysis of 93 stomachs contents showed that food resources associated with the substrate, such as plant remains, detritus, fish scales and Chironomidae larvae, dominated the diet. Consequently this species was characterized as a detritivorous-invertivorous. However, individuals collected in 2003 showed a greater selection of benthic organisms in relation to previous periods. Morphological structures such as position of the mouth, form of the lips, gill rakers and pharyngeal...

Autores: Souza,Luiz Antonio de; Iwazaki,Maisa C.; Moscheta,Ismar S.
The morphology and anatomy of the fruit and seed of Tabebuia chrysotricha (Mart. ex DC.) Standl. (Bignoniaceae), a species typical of the Atlantic rainforest, is presented and discussed. The fruit was a loculicidal capsule, dehiscing through two slits, liberating a seminiferous column. The dehiscence process of the fruit involved separation tissue and two crossed sclerenchymatous mesocarpic layers (middle and subepidermic). The seed originated from an anatropous, unitegmic and tenuinucellate ovule. It was exotestal and presented polyembriony. The endothelium and endosperm were conserved in the mature seed and protected the embryo. Adventive embryos were made up of hypostase cells.

Autores: Margabandhu,M.; Sendhilnathan,S.; Senthilkumar,S.; Gajalakshmi,D.
ABSTRACT In the present work, Cu2+ substituted cobalt ferrite (Co1-xCuxFe2O4, x = 0, 0.3, 0.5, 0.7 and 1) magnetic nanopowders were synthesized via chemical co-precipitation method. The prepared powders were investigated by various characterization methods such as X-ray diffraction analysis (XRD), scanning electron microscope analysis (SEM), vibrating sample magnetometer analysis (VSM) and fourier transform infrared spectroscopy analysis (FTIR). The XRD analysis reveals that the synthesized nanopowders possess single phase centred cubic spinel structure. The average crystallite size of the particles ranging from 27-49 nm was calculated by using Debye-scherrer formula. Magnetic properties of the synthesized magnetic nanoparticles are studied by using VSM....

Effects of the organophosphorous methyl parathion on the branchial epithelium of a freshwater fish Metynnis roosevelti
Provedor de dados: 52
Autores: Machado,Marcelo Rubens; Fanta,Edith.
Gills are vital structures for fish, since they are the main site for gaseous exchange as well as partially responsible for osmorregulation, acid-basic balance, excretion of nitrogenous compounds and taste. Chemicals in the water may alter the morphology of branchial cells of fish that are, therefore, a useful model for environmental impact and ecotoxicology studies. In order to investigate the effects of an organophosphorous compound, methyl parathion, on the gills of the fish, samples of Metynnis roosevelti were exposed to lethal (7ppm) and sublethal (1ppm) doses of Mentox 600 CE. Through light and scanning electron microscopy, shrinking of the branchial epithelium, followed by detachment and hyperplasia were observed. Externally, the branchial filaments...

Gills scanning images of the seawater fish Eugerres brasilianus (Gerreidae)
Provedor de dados: 52
Autores: Eiras-Stofella,Daura Regina; Charvet-Almeida,Patricia.
The gills of the adult fish, Eugerres brasilianus (Gerreidae) were analyzed in a scanning electron microscope. The stratified epithelium was uniform on all parts of the branchial arch. Concentric microridges were present on cells that form this epithelium and were mainly observed in the primary lamellae and pharyngeal region where mucous cells were also abundant. The ultrastructural features of E. brasilianus gills indicated that this was not a filtering species, and that the feeding habit included mainly the intake of small organisms. The results presently obtained agreed with other literature data which determined the feeding habit of this species by means of stomach content analysis and other aspects.

Hoplias malabaricus (traíra) were experimentally starved (0 to 240 days) and subsequently re-fed for 30 days (after 90 and 240-d fasting). Long-term starvation produced minor changes in muscle composition, but shrinkage of muscle fibres was a conspicuous result. The diameter of muscle fibres decreased gradually and the spaces among them increased as the starvation period progressed. After re-feeding, fish prior starved for 90 days presented partial restoration on diameter of muscle fibres. However, the fibres remained shrunken after re-feeding following 240-d fasting. While the lipid content did not change, the protein levels fell after 240-d fasting, but they were restored after re-feeding

Identification of Primordial Germ Cells: Cytological, Histological and Immunohistochemical Aspects
Provedor de dados: 52
Autores: Yön,Nazan Deniz; Akbulut,Cansu.
Primordial germ cells (PGCs) constitute an embryonic cell type that migrate to gonadal precursors and form the gametes. In many animals, PGCs are set apart from somatic cells early during embryogenesis. These cells migrate to gonadal precursors and then constitute gonads so they are useful models for cell motility studies. They have a highlighted importance for development and reproduction studies. Primordial germ cells have morphological differences from the somatic cells. Structure of these cells can be detected with light and electron microscopy in early development stages. This review describes the morphological, histological, molecular and ultrastructural features of primordial germ cells in different animals and gives an overview for simplified...

Autores: ABDALLA,F. C.; CRUZ-LANDIM,C. da.
Associated to the sting apparatus of the aculeate hymenopterans is found the poison gland, originated from the glands associated to the ovipositor of the non-aculeate hymenopterans and the less derived Dufour gland, homologue of the coletterial gland of other insects, and found in all hymenopteran females. The Dufour gland functions is mostly uncertain in hymenopterans but in ants it is involved with communication and defense and in non social bees with the nest building and protection. In wasps possibly with kin-recognition. Differences in morphology and chemical composition of the gland secretion were observed among species, in the same species, between the castes in the social species and among individual of the same caste playing different tasks or...

Autores: Pal,Rahul; Hameed,Saif; Sharma,Sharda; Fatima,Zeeshan.
ABSTRACT Novel strategies to combat the ever increasing burden of drug resistance in Mycobacterium tuberculosis (MTB) causing tuberculosis (TB) remains a global concern. The ability of MTB to sense and adapt to restricted iron conditions in the hostile environment is essential for their survival and confers the basis of their success as dreadful pathogen. The striking and clinically relevant virulence trait of MTB is its ability to form biofilms and adhere to the host cells. The present study elucidated the effect of iron deprivation on biofilm formation and cell adherence of Mycobacterium smegmatis, a non-pathogenic surrogate of MTB. Firstly, we showed that iron deprivation leads to enhanced cell sedimentation rate and altered colony morphology depicting...

Quantitative studies of the vasculature of the carotid body in the chronically hypoxic rat
Provedor de dados: 56
Autores: Clarke,J.A.; Daly,M. de B.; Marshall,J.M.; Ead,H.W.; Hennessy,E.M.
The carotid bodies of rats made chronically hypoxic by breathing 12% O2 in a normobaric chamber (inspired PO2 91 mmHg) were compared with those of controls. Serial 5-µm sections of the organs were examined using an interactive image analysis system. The total volume of the carotid bodies was increased by 64%. The total vascular volume rose by 103% and was likely due to an increase in size of the large vessels (&amp;gt;12 µm lumen diameter) because the small vessel (5-12 µm lumen diameter) volume did not increase significantly while the small vessel density tended to decrease. The extravascular volume was increased by 57%. Expressed as a percentage of the total volume of the organ, the total vascular volume did not change, but the small vessel volume was...

Diets rich in saturated fatty acids are one of the most important causes of atherosclerosis in men, and have been replaced with diets rich in unsaturated fatty acids (UFA) for the prevention of this disorder. However, the effect of UFA on myocardial performance, metabolism and morphology has not been completely characterized. The objective of the present investigation was to evaluate the effects of a UFA-rich diet on cardiac muscle function, oxidative stress, and morphology. Sixty-day-old male Wistar rats were fed a control (N = 8) or a UFA-rich diet (N = 8) for 60 days. Myocardial performance was studied in isolated papillary muscle by isometric and isotonic contractions under basal conditions after calcium chloride (5.2 mM) and ß-adrenergic stimulation...

Autores: Stancu,Mihaela Marilena.
Abstract Recently, there has been a lot of interest in the utilization of rhodococci in the bioremediation of petroleum contaminated environments. This study investigates the response of Rhodococcus erythropolis IBBPo1 cells to 1% organic solvents (alkanes, aromatics). A combination of microbiology, biochemical, and molecular approaches were used to examine cell adaptation mechanisms likely to be pursued by this strain after 1% organic solvent exposure. R. erythropolis IBBPo1 was found to utilize 1% alkanes (cyclohexane, n-hexane, n-decane) and aromatics (toluene, styrene, ethylbenzene) as the sole carbon source. Modifications in cell viability, cell morphology, membrane permeability, lipid profile, carotenoid pigments profile and 16S rRNA gene were...

Applications of image analysis in the characterization of Streptomyces olindensis in submerged culture
Provedor de dados: 58
Autores: Pamboukian,Celso R. Denser; Guimarães,Luciana M.; Facciotti,Maria Cândida R.
The morphology of Streptomyces olindensis (producer of retamycin, an antitumor antibiotic) grown in submerged culture was assessed by image analysis. The morphology was differentiated into four classes: pellets, clumps (or entangled filaments), branched and unbranched free filaments. Four morphological parameters were initially considered (area, convex area, perimeter, and convex perimeter) but only two parameters (perimeter and convex perimeter) were chosen to automatically classify the cells into the four morphological classes, using histogram analysis. Each morphological class was evaluated during growth carried out in liquid media in fermenter or shaker. It was found that pellets and clumps dominated in early growth stages in fermenter (due to the...

ABSTRACT: The objective of the present study was to evaluate the effect of gender on the growth of Criollo foals, in order to use this information as a reference for breeding as well as in future research. Body height, thoracic perimeter, and cannon bone perimeter of 75 foals were measured from two farms in Rio Grande do Sul, Brazil (Lat. 32°, 33′, 58″, Long. 53°, 22′, 33″) and from three generations over three years. In both farms, animals were kept under the same range and feeding conditions. Nonlinear regression models were applied to describe the growth curves for the three traits over the experimental period. Cannon bone perimeter was greater in males than in females (P&lt;0.001) but the predicted curves for body height and thoracic perimeter did not...

Autores: Pimentel,Cláudio Alves; Hammes,Anelise Maria; Dietrich,Giovani.
In a breeding farm, 129 mares were bred to 4 stallions and had an overall pregnancy rate of 76.7%. Stailions were submitted to semen examination for at least two times at the beginning of the breeding season and the percentage of morphologically normal spermatozoa were used for statistical analysis in relation to the percentage of pregnancy at the end of the breeding season. A regression analysis revealed that the percentage of pregnancy (y) can be estimated by the percentage of normal spermatozoa (x) in the ejaculate according to the following equation: y=52.38+0.44x; r2=97.8%; P&lt;0.01. We concluded that the pregnancy rate can be estimated by the percentage of morphologically normal spermatozoa in the ejaculate of stallions, since it is an importam...

MORPHOLOGICAL RESPONSE OF THE RUMINAL AND OMASAL MUCOSAE TO THE VARIATION IN DIET ENERGY
Provedor de dados: 64
Autores: Lima,Ronaldo Francisco; Resende Júnior,João Chrysostomo; Costa,Suely Fátima; Daniel,João Luiz Pratti; Teófilo,Tiago Silva; Cardoso,Milton Ghedini.
ABSTRACT The absorption capacity of the rumen responds positively to direct and indirect stimulation by VFA; there is also evidence that the wall of the omasum also responds to these stimuli. To further investigate these reports, we compared the tissue morphologies of rumen and omasum biopsy samples. Four cows surgically fitted with ruminal cannulas were sequentially fed two diets. These diets included corn silage (S) and a combination of corn silage and commercial concentrate (CS). The animals were fed S for the first 18 days of the experiment, followed by CS for the next 18 days. They were then fasted for 72 h (F), and then had at least 18 days of re-feeding. Biopsy samples were taken from the blade of the omasum and the ventral sac of the rumen at...

Provedor de dados: 64
Autores: Daniel,João Luiz Pratti; Resende Júnior,João Chrysostomo de.
Volatile fatty acids (VFA) absorption and metabolic capacity of rumen and omasum were compared, in vitro. Fragments of rumen wall and omasum laminae were taken from eight adult crossbred bovines. An isolated fragment of the mucosa was fitted in a tissue diffusion chamber. Valeric acid and CrEDTA were added to ruminal fluid and placed on the mucosal side and buffer solution was placed on the serosal side. Fractional absorption rates were measured by exponential VFA:Cr ratio decay over time. Metabolism rate was determined as the difference between VFA absorbed and VFA which appeared on the serosal side over time. Mitotic index was higher in omasum (0.52%) than in rumen epithelium (0.28%). VFA fractional absorption rate was higher in omasum (4.6%/h.cm²) than...
