Areas of endemism in the southern central Andes
Provedor de dados: 66
Autores: Aagesen,Lone; Bena,Maria J.; Nomdedeu,Soledad; Panizza,Adela; López,Ramiro P.; Zuloaga,Fernando O.
This paper analyzes the distribution of vascular plants species endemic to the southern central Andes (south-western Bolivia and north-western Argentina). All 540 species endemic to the study regions (approx. 720600 km²) have been included in the analysis. The main part of the endemic species is found in semiarid habitats between 1500-3500 m asl pointing to the topographically complex plateau, slope, and valley system of the southern central Andes as the main locations for its endemic flora. The distribution of the endemic species within arid sites is in contrast with that of vascular plant diversity in general, as the most diverse habitat of the region is the moist subtropical Tucumano-Bolivian Yungas forest of the eastern Andes slope. A total of 17 well...

Bruce; U.S. Environmental Protection Agency, National Exposure Research Laboratory; jones.bruce@epa.gov; Smith, Elizabeth; U.S. Environmental Protection Agency, National Exposure Research Laboratory; smith.betsy@epa.gov.
We report an analysis of forest fragmentation based on 1-km resolution land-cover maps for the globe. Measurements in analysis windows from 81 km 2 (9 x 9 pixels, &amp;#8220;small&amp;#8221; scale) to 59,049 km 2 (243 x 243 pixels, &amp;#8220;large&amp;#8221; scale) were used to characterize the fragmentation around each forested pixel. We identified six categories of fragmentation (interior, perforated, edge, transitional, patch, and undetermined) from the amount of forest and its occurrence as adjacent forest pixels. Interior forest exists only at relatively small scales; at larger scales, forests are dominated by edge and patch conditions. At the smallest scale, there were significant differences in fragmentation among continents; within continents,...

BIOGEOGRAPHY OF DEEP-WATER CHEMOSYNTHETIC ECOSYSTEMS (CHESS): EXPLORING THE SOUTHERN OCEANS
Provedor de dados: 72
Autores: Ramírez Llodra,Eva; Tyler,Paul A; German,Christopher R.
The vast majority of the mid-ocean ridge system and of the continental margins around the globe have not yet been explored. A relatively small number of vent and seep sites have been analysed and are the focus of long-term research programmes. However, the exploration of new areas will certainly provide the discovery of new vent and seep sites. Furthermore, the study of these key locations will lead to the description of new species and improve our understanding of the abundance, diversity, and distribution of species from chemosynthetically-driven systems around the world's oceans. It is the aim of ChEss to develop an exploration field phase to discover new deep-water hydrothermal vents and cold seeps at key locations, to describe their fauna, and to...

Distributional patterns of the South American species of Hyalella (Amphipoda: Hyalellidae)
Provedor de dados: 72
Autores: De los Ríos-Escalante,Patricio; Morrone,Juan J; Rivera,Reinaldo.
Distributional patterns of the South American species of the freshwater amphipod genus Hyalella were analysed using a panbiogeographic approach. Five generalized tracks were found: (1) northern Andes to Lake Titicaca (H. dielaii, H. meinerti, H. dybowskii, H.jelskii, H. lubominsky, and H. pauperocavae; (2) lake Titicaca (H. armata, H. cuprea, H. latinamus, H. lucifugax, H. montforti, H. neveulemairei, H. robusta, H. tiwanaku, H. simplex simplex, and H. solida); (3) central Andes (H. fossamancinii and H. kochi); (4) Pampas (H. bonariensis, H. caeca, H. castroi, H. longispina, H. montenegrinae, H. pampeana, H. pernix, H. pseudoazteca, and H. warmingii); and (5) Subantarctic (H. patagonica H. costera, H. curvispina, H. chiloensis, H. falklandensis, H....

Pelagic Biodiversity and Biogeography around the SouthAmerican continent
Provedor de dados: 72
Autores: Pierrot-Bults,Annelies C.
Biogeography around South America is well documented on the Atlantic side and less well documented on the Pacific side especially south of about 30º S. The South Pacific oceanic areas are the least known of all pelagic areas. The different approaches to determine biogeographic provinces (e.g. the classical one showing mainly latitudinal and watermass distribution patterns based on presence/absence of species; and the biogeochemical approach based on productivity regimes and modelling) are discussed. The latter shows more east-west division. Testing of these concepts will probably reveal more coastal provinces in the Pacific area. The transitional area in the South Pacific is also an interesting area for molecular species research because there are some...

Evolutionary change in the germination niche between related species within Neoporteria clade (Cactaceae) is idiosyncratic to habitat type
Provedor de dados: 73
Autores: Guerrero,Pablo C.; Mardones,Daniela; Viveros,Nataly; Peña-Gómez,Francisco T.; Bustamante,Ramiro O.
ABSTRACT An appropriate germination response to environmental conditions is the first requirement for the establishment of a plant in a determined geographic area; therefore changes in the germination niche may be critical in configuring the current pattern of species distributions. Furthermore, the spread of many Neotropical groups to higher latitudes are constrained by the combination of cold and humid conditions. This raises the question whether evolutionary trends in germination niche are essential for the mechanism that allows the colonization of edge habitats characterized by humid and cold conditions. Here, we evaluated the variation of seed germination probabilities of two species of cacti (Neoporteria clade), closely related but endemic to...

Molecular identification, phylogeny and geographic distribution of Brazilian mangrove oysters (Crassostrea)
Provedor de dados: 74
Autores: Melo,Aline Grasielle Costa de; Varela,Eduardo Sousa; Beasley,Colin Robert; Schneider,Horacio; Sampaio,Iracilda; Gaffney,Patrick Michael; Reece,Kimberly S.; Tagliaro,Claudia Helena.
Oysters (Ostreidae) manifest a high degree of phenotypic plasticity, whereby morphology is of limited value for species identification and taxonomy. By using molecular data, the aim was to genetically characterize the species of Crassostrea occurring along the Brazilian coast, and phylogenetically relate these to other Crassostrea from different parts of the world. Sequencing of the partial cytochrome oxidase c subunit I gene (COI), revealed a total of three species of Crassostrea at 16 locations along the Brazilian coast. C. gasar was found from Curuçá (Pará state) to Santos (São Paulo state), and C. rhizophorae from Fortim (Ceará state) to Florianópolis (Santa Catarina state), although small individuals of the latter species were also found at Ajuruteua...

The historical biogeography of  Pteroglossus  aracaris (Aves, Piciformes, Ramphastidae) based on Bayesian analysis of mitochondrial DNA sequences
Provedor de dados: 74
Autores: Pereira,Sérgio L.; Wajntal,Anita.
Most Neotropical birds, including  Pteroglossus  aracaris, do not have an adequate fossil record to be used as time constraints in molecular dating. Hence, the evolutionary timeframe of the avian biota can only be inferred using alternative time constraints. We applied a Bayesian relaxed clock approach to propose an alternative interpretation for the historical biogeography of  Pteroglossus  based on mitochondrial DNA sequences, using different combinations of outgroups and time constraints obtained from outgroup fossils, vicariant barriers and molecular time estimates. The results indicated that outgroup choice has little effect on the Bayesian posterior distribution of divergence times within  Pteroglossus , that geological and molecular time constraints...

New molecular evidence supports the species status of Kaempfer's Woodpecker (Aves, Picidae)
Provedor de dados: 74
Autores: Azevedo,Lorena de Sousa; Aleixo,Alexandre; Santos,Marcos Pérsio Dantas; Sampaio,Iracilda; Schneider,Horacio; Vallinoto,Marcelo; Rêgo,Péricles Sena do.
Kaempfer's Woodpecker (Celeus obrieni) is the only species of the genus Celeus endemic to Brazil. The description of this taxon as a subspecies of the Rufous-headed Woodpecker (Celeus spectabilis) was based on a single specimen. While C. obrieni and C. spectabilis are now considered separate species based on morphological and limited molecular evidence, no study has critically tested the reciprocal monophyly and degree of evolutionary independence between these taxa with several specimens. Herein, fragments of the mitochondrial and nuclear DNA of three recently-collected specimens of C. obrieni were analyzed to evaluate the degree of evolutionary differentiation of this taxon with respect to C. spectabilis. The results confirm the reciprocal monophyly...

Comparative cytogenetics among species of the Astyanax scabripinnis complex: evolutionary and biogeographical inferences
Provedor de dados: 74
Autores: Vicari,Marcelo Ricardo; Noleto,Rafael Bueno; Artoni,Roberto Ferreira; Moreira-Filho,Orlando; Bertollo,Luiz Antonio Carlos.
Karyotype data are presented for distinct species of the genus Astyanax from four rivers belonging to three different hydrographic basins of the State of Paraná, Brazil (Verde River - Tibagi basin, Açungui River - Ribeira basin, and Santo Antônio and Jaguariaíva Rivers - Jaguariaíva basin). Three karyotypic forms were identified, here denominated karyotype A (2n = 50 chromosomes, with 8m+18sm+10st+14a, and thirteen 18S rDNA sites); karyotype B (2n = 50 chromosomes, with 8m+18sm+10st+1f4a, and four 18S rDNA sites); and karyotype C (2n = 48 chromosomes, with 10m+16sm+10st+12a, and eight 18S rDNA sites). The pattern of constitutive heterochromatin was similar among the three karyotypic forms, with few differences. The 5S rDNA corresponds to a synapomorphic...

Phylogenetic relationships among Capuchin (Cebidae, Platyrrhini) lineages: An old event of sympatry explains the current distribution of Cebus and Sapajus
Provedor de dados: 74
Autores: Martins-Junior,Antonio Marcio Gomes; Carneiro,Jeferson; Sampaio,Iracilda; Ferrari,Stephen F.; Schneider,Horacio.
Abstract Capuchin monkeys are currently represented by four species of Cebus and eight of Sapajus. This group is taxonomically complex and several questions still need to be clarified. In the current study, using mtDNA markers and a larger sample representation than in previous studies, we seek to understand the phylogenetic relationships among the capuchin lineages and their historical biogeography. All 12 species of capuchins were analyzed for the mitochondrial Control Region and Cytochrome b to test two biogeographical hypotheses: “Reinvasion of the Amazon (ROA)” and “Sympatric Evolution (SEV)”. The phylogenetic relationships among distinct lineages within genera is consistent with an evolutionary diversification pattern probably resulting from an...

Provedor de dados: 74
Autores: Muschner,Valéria C.; Zamberlan,Priscilla M.; Bonatto,Sandro L.; Freitas,Loreta B.
As part of a long-term investigation on the evolution of Passiflora L., we investigated the divergence ages of the genus and diversification of its subgenera, relating them with biogeographical and/or historical events, and other characteristics of this taxon. The main aim of the present work was to evaluate the biogeographic distribution of this genus to better understand its evolutionary history. This is the first time that representatives from South American and Old World Passifloraceae genera have been studied as a group comprising a total of 106 widely distributed species, with representative samples of the four suggested subgenera. Seven DNA regions were studied, comprising 7,431 nucleotides from plastidial, mitochondrial and nuclear genomes....

Autores: Abatzopoulos, Th. J.; Amat, F.; Baxevanis, A. D.; Belmonte, G.; Hontoria, F.; Maniatsi, S.; Moscatello, S.; Mura, G.; Shadrin, N. V.
Artemia urmiana (a species previously considered endemic of Lake Urmia, NW Iran) has been found in Lake Koyashskoe, a hypersaline lake on the Black Sea coast of the Crimean peninsula (Ukraine). Therefore, this is the first record of A. urmiana in Europe which updates its distribution. The species identification was based on an integrated and interdisciplinary approach using discriminant analysis of the morphometric characters, scanning electron microscopy, and molecular profile analysis. The data derived from the above mentioned approaches converge to significant similarity of the population under investigation with A. urmiana. The updated geographic distribution of the species, deriving from the present report, asks for additional contribution of other...

Areas of endemism in the Brazilian Atlantic Forest based on the distribution of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae)
Provedor de dados: 76
Autores: Silva,Jorge L. da; Vaz-de-Mello,Fernando Z.
ABSTRACT Our goals were to determine whether the pattern of geographical distribution of dung beetles in the Brazilian Atlantic Forest (BAF), Southeast Brazil, supports the identification of the areas of endemism in this biome, how the number and boundaries of the areas of endemism vary with the spatial scale used in the analysis, if the areas of endemism identified here are consistent with previous proposals described in the literature. We used the analysis of endemicity (NDM) on the distributional patterns of 198 species and subspecies of dung beetles in order to identify areas of endemism into grids of 0.25°x0.25°, 0.5°x0.5° and 1°x1°. A total of 15 consensus areas (CA) were identified with the different grid sizes employed (two of 0.25°, three of 0.5°...

A closer look at Batillipes dicrocercus and new records of Batillipes potiguarensis (Tardigrada: Arthrotardigrada) from the Brazilian coast with comments on intra- and interspecific variability
Provedor de dados: 76
Autores: Santos,Érika; Gomes Jr,Edivaldo; Rocha,Clélia M. C. da; Bartels,Paul J.; Fontoura,Paulo.
ABSTRACT Batillipes specimens collected in the Southwestern Atlantic Ocean, on the Brazilian Coast (Campos Basin and Potiguar Basin) with a bifurcated caudal appendage similar to B. dicrocercus Pollock, 1970 were assigned to B. potiguarensis Santos, da Rocha, Gomes Jr &amp; Fontoura, 2017. This species was described as having a roundish caudal protrusion but, as shown in this study, it exhibits intraspecific variability of the morphology of the caudal apparatus. The examination of specimens of B. dicrocercus from the type locality (Massachussetts, U.S.A.) and the analysis of the original description and two subsequent emended descriptions, one from the Gulf of Mexico (U.S.A.) and another from the Mediterranean Sea, used for comparison, revealed important...

Molecular phylogenies, chromosomes and dispersion in Brazilian akodontines (Rodentia, Sigmodontinae)
Provedor de dados: 76
Autores: Barros,Maria Claudene; Sampaio,Iracilda; Schneider,Horacio; Langguth,Alfredo.
A new molecular phylogeny for akodontine rodents from Brazil was proposed. The phylogenetic tree was enriched with the area of occurrence and with information on the karyotype of the samples. Based on this enriched tree, and with a described methodology, hypotheses were proposed on the karyotype and area of occurrence of the ancestors of each Clade. Thus it was possible to discuss hypotheses on chromosome evolution of the group, and on dispersion events from the "area of original differentiation" of akodontines in the Andes. Chromosome evolution started with high diploid numbers (2n=52) and showed a tendency to reduction (until 2n=14 in more recent clades). Independent side-branches of the tree showed 2n reduction and in one case the 2n increased. At least...

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...

Peripatric speciation drives diversification and distributional pattern of reef Hermit Crabs (Decapoda: Diogenidae: Calcinus)
Provedor de dados: 5
Autores: Malay, Maria Celia (machel) D.; Paulay, Gustav.
The diversity on coral reefs has long captivated observers. We examine the mechanisms of speciation, role of ecology in speciation, and patterns of species distribution in a typical reef-associated clade-the diverse and colorful Calcinus hermit crabs-to address the origin of tropical marine diversity. We sequenced COI, 16S, and H3 gene regions for similar to 90% of 56 putative species, including nine undescribed, "cryptic" taxa, and mapped their distributions. Speciation in Calcinus is largely peripatric at remote locations. Allopatric species pairs are younger than sympatric ones, and molecular clock analyses suggest that &gt; 2 million years are needed for secondary sympatry. Substantial niche conservatism is evident within clades, as well as a few major...

The ichthyofauna of Reunion Island, Southwestern Indian Ocean, was sampled during several ecological and artisanal fisheries studies. Information from these investigations and from other sources were included to compile the present checklist of the marine fishes of the island. A total of 885 species belonging to 150 families was recorded. Nine species are known only from Reunion, indicating endemism of about 1.0%. The most speciose families (Labridae, Gobiidae, Serranidae, and Pomacentridae) were also among the most speciose at the neighbouring Mauritius Island (except gobiids), and, generally, on other islands in the Indian Ocean area (Maldives, Chagos, Madagascar and Christmas Island). The Gobiidae only represented 5.4% of the ichthyofauna, which was...

Assessing the sensitivity of bivalve populations to global warming using an individual-based modelling approach
Provedor de dados: 5
Autores: Thomas, Yoann; Bacher, Cedric.
Climate change exposes benthic species populations in coastal ecosystems to a combination of different stressors (e.g. warming, acidification and eutrophication), threatening the sustainability of the ecological functions they provide. Thermal stress appears to be one of the strongest drivers impacting marine ecosystems, acting across a wide range of scales, from individual metabolic performances to geographic distribution of populations. Accounting for and integrating the response of species functional traits to thermal stress is therefore a necessary step in predicting how populations will respond to the warming expected in coming decades. Here, we developed an individual‐based population model using a mechanistic formulation of metabolic processes...

Evolutionary Patterns in Pearl Oysters of the Genus Pinctada (Bivalvia: Pteriidae)
Provedor de dados: 5
Autores: Cunha, Regina L.; Blanc, Francoise; Bonhomme, Francois; Arnaud-haond, Sophie.
Pearl oysters belonging to the genus Pinctada (Bivalvia: Pteriidae) are widely distributed between the Indo-Pacific and western Atlantic. The existence of both widely distributed and more restricted species makes this group a suitable model to study diversification patterns and prevailing modes of speciation. Phylogenies of eight out of the 11 currently recognised Pinctada species using mitochondrial (cox1) and nuclear (18S rRNA) data yielded two monophyletic groups that correspond to shell size and presence/absence of hinge teeth. Character trace of these morphological characters onto the molecular phylogeny revealed a strong correlation. Pinctada margaritifera appears polyphyletic with specimens from Mauritius grouping in a different clade from others of...

Diversity and spatial distribution of amoA-encoding archaea in the deep-sea sediments of the tropical West Pacific Continental Margin
Provedor de dados: 5
Autores: Dang, H.; Li, J.; Zhang, X.; Li, T.; Tian, F.; Jin, W.
The ecological characteristics of the deep-sea amoA-encoding archaea (AEA) are largely unsolved. Our aim was to study the diversity, structure and distribution of the AEA community in the sediments of the tropical West Pacific Continental Margin, to develop a general view of the AEA biogeography in the deep-sea extreme environment. Archaeal amoA clone libraries were constructed. Diverse and novel amoA sequences were identified, with the Bohol Sea, Bashi Strait and Sibuyan Sea harbouring the highest and the Bicol Shelf the lowest AEA diversity. Phylogenetic and statistical analyses illustrate a heterogeneous distribution of the AEA community, probably caused by the differential distribution of the terrestrial or estuarine AEA in the various sampling sites....

Climate hindcasts: exploring the disjunct distribution of     Diopatra biscayensis
Provedor de dados: 5
Autores: Wethey, David S.; Woodin, Sarah A.; Berke, Sarah K.; Dubois, Stanislas.
The ecosystem engineer onuphid polychaete Diopatra biscayensis has a continuous population in the Bay of Biscay from the Cantabria coast in Spain to southern Brittany in France. A group of disjunct populations also are found in the English Channel, separated from the Biscay population by more than 400 coastal kilometers. It remains unclear whether D. biscayensis is native to the Bay of Biscay; it is also debated whether the disjunct populations in the English Channel are relics of a formerly continuous population, or the product of recent introductions through aquaculture. Here, we use climate hindcasts to explore hypotheses about the D. biscayensis historical distribution in Europe. If D. biscayensis is native, its range would have been restricted to...

Aim To investigate some of the environmental variables underpinning the past and present distribution of an ecosystem engineer near its poleward range edge. Location &gt;500 locations spanning &gt;7,400 km around Ireland. Methods We collated past and present distribution records on a known climate change indicator, the reef‐forming worm Sabellaria alveolata (Linnaeus, 1767) in a biogeographic boundary region over 182 years (1836–2018). This included repeat sampling of 60 locations in the cooler 1950s and again in the warmer 2000s and 2010s. Using species distribution modelling, we identified some of the environmental drivers that likely underpin S. alveolata distribution towards the leading edge of its biogeographical range in Ireland.

Cenozoic climate change and diversification on the continental shelf and slope: evolution of gastropod diversity in the family Solariellidae (Trochoidea)
Provedor de dados: 5
Autores: Williams, S. T.; Smith, L. M.; Herbert, D.g.; Marshall, B. A.; Waren, A.; Kiel, S.; Dyal, P.; Linse, K.; Vilvens, C.; Kano, Y.
Recent expeditions have revealed high levels of biodiversity in the tropical deep-sea, yet little is known about the age or origin of this biodiversity, and large-scale molecular studies are still few in number. In this study, we had access to the largest number of solariellid gastropods ever collected for molecular studies, including many rare and unusual taxa. We used a Bayesian chronogram of these deep-sea gastropods (1) to test the hypothesis that deep-water communities arose onshore, (2) to determine whether Antarctica acted as a source of diversity for deep-water communities elsewhere and (3) to determine how factors like global climate change have affected evolution on the continental slope. We show that although fossil data suggest that solariellid...

Autores: Boo, Ga Hun; Zubia, Mayalen; Hughey, Jeffery R.; Sherwood, Alison R.; Fujii, Mutue T.; Boo, Sung Min; Miller, Kathy Ann.
Although complete mitogenomic data have been widely applied in human and other animal population studies, they are extremely limited for florideophycean red algal populations. Gelidiella fanii is a recently described rhodophyta, previously misidentified as G. acerosa, a cosmopolitan agar-yielding species from tropical to subtropical waters. To decipher patterns in genetic diversity and geographic distribution for G. fanii, we obtained 10 complete mitogenomes including two outgroups, G. acerosa and G. flabella. The mitogenomes ranged in size from 25,223 to 25,281 bp and had 48 genes, which are similar in general structure, gene order and content, and presence of a group II intron. Phylogenomic analysis revealed that G. fanii was monophyletic and clearly...

A perspective on the census of marine life. The role of natural history institutions for this programme
Provedor de dados: 5
Autores: Pierrot-bults, Ac.
The Census of marine life programme (CoML) is expected to generate a large amount of information on the diversity, distribution, and abundance of marine communities, many of them new or poorly known. Institutions such as natural history museums can play a crucial role in providing the necessary tools to allow the CoML to advance knowledge in the fields of marine systematics and biogeography. These institutions can contribute taxonomic expertise to provide quality-controlled identifications of species; specimen collections to allow for cross-checking of occurrences and a historical context for new data; information, both paper and electronic, on taxonomy, ecology and other topics to enable researchers to review past work; education opportunities to inform...

Assessing spatial and temporal variability of phytoplankton communities' composition in the Iroise Sea ecosystem (Brittany, France): A 3D modeling approach: Part 2: Linking summer mesoscale distribution of phenotypic diversity to hydrodynamism
Provedor de dados: 5
Autores: Cadier, Mathilde; Sourisseau, Marc; Gorgues, Thomas; Edwards, Christopher A.; Memery, Laurent.
Tidal front ecosystems are especially dynamic environments usually characterized by high phytoplankton biomass and high primary production. However, the description of functional microbial diversity occurring in these regions remains only partially documented. In this article, we use a numerical model, simulating a large number of phytoplankton phenotypes to explore the three-dimensional spatial patterns of phytoplankton abundance and diversity in the Iroise Sea (western Brittany). Our results suggest that, in boreal summer, a seasonally marked tidal front shapes the phytoplankton species richness. A diversity maximum is found in the surface mixed layer located slightly west of the tidal front (i.e., not strictly co-localized with high biomass...

Autores: Luo, Zhaohe; Krock, Bernd; Mertens, Kenneth; Nezan, Elisabeth; Chomerat, Nicolas; Bilien, Gwenael; Tillmann, Urban; Gu, Haifeng.
The marine planktonic dinophyceaen genus Azadinium is a primary source of azaspiracids, but due to their small size its diversity may be underestimated and information on its biogeography is still limited. A new Azadinium species, A. zhuanum was obtained from the East China Sea and Yellow Sea of China by incubating surface sediments. Five strains were established by isolating single germinated cells and their morphology was examined with light microscopy and scanning electron microscopy. Azadinium zhuanum was characterized by a plate pattern of Po, cp, X, 4′, 2a, 6′′, 6C, 5S, 6′′′, 2′′′′, by a distinct ventral pore at the junction of Po, the first and fourth apical plates, and a conspicuous antapical spine. Moreover, Azadinium poporum was obtained for the...

Diversity, Distribution and Phylogeny of Hesionidae (Annelida) Colonizing Whale Falls: New Species of Sirsoe and Connections Between Ocean Basins
Provedor de dados: 5
Autores: Shimabukuro, Mauricio; Carrerette, Orlemir; Alfaro-lucas, Joan Manel; Rizzo, Alexandra Elaine; Halanych, Kenneth M.; Sumida, Paulo Yukio Gomes.
Whale falls are important environments contributing to biodiversity, connectivity and evolutionary novelty in deep-sea ecosystem. Notwithstanding, most of this knowledge is based in studies from NE Pacific basin. Interestingly, the only known natural whale fall on the SW Atlantic has faunal composition affinities with carcasses from other deep-ocean basins. In this carcass, annelid worms belonging to Hesionidae are abundant and species-rich, and include some shared species with NE Pacific Ocean. Here we evaluate the diversity of Hesionidae on the SW Atlantic using new information of implanted whale bones and explore whether some species have interbasin distribution or if they represent cryptic species in different basins. We described, using morphological...

Within the COST action EMBOS (European Marine Biodiversity Observatory System) the degree and variation of the diversity and densities of soft-bottom communities from the lower intertidal or the shallow subtidal was measured at 28 marine sites along the European coastline (Baltic, Atlantic, Mediterranean) using jointly agreed and harmonized protocols, tools and indicators. The hypothesis tested was that the diversity for all taxonomic groups would decrease with increasing latitude. The EMBOS system delivered accurate and comparable data on the diversity and densities of the soft sediment macrozoobenthic community over a large-scale gradient along the European coastline. In contrast to general biogeographic theory, species diversity showed no linear...

Temperature effect on survival, growth, and triacylglycerol content during the early ontogeny of Mytilus edulis and M. trossulus
Provedor de dados: 5
Autores: Rayssac, Nathalie; Pernet, Fabrice; Lacasse, Olivia; Tremblay, Rejean.
Temperature is a major factor contributing to the biogeography of intertidal poikilotherms. The population dynamics of intertidal invertebrates like mussels are strongly dependent on larval supply and larval mortality. Unlike adults, which are resistant to fluctuating environmental conditions, larvae are highly sensitive to the physicochemical conditions of the pelagic zone. The effects of rearing temperature on larval and post-larval performance of 2 coexisting mussels species, Mytilus edulis and M. trossulus, were examined in this study. In the first experiment, larvae of both species were reared separately at constant temperatures of 10, 17, and 24 degrees C from D-larvae to the dissoconch stage. In the second experiment, pediveligers were reared under...

Autores: Tyler, Pa; German, Cr; Ramirez-llodra, E; Van Dover, Cl.
ChEss is a recently-funded Census of marine life programme aimed at improving our knowledge of the biogeography of deepwater chemosynthetically driven ecosystems by promoting an international field phase of discovery and exploration. The main objectives are to assess and explain the diversity, distribution and abundance of hydrothermal vent and cold seep species. With the global mid-ocean ridge system extending similar to65000 km, it is unlikely that its entire length would be examined in detail. The ChEss programme proposes to select a limited number of target areas chosen for the discovery of new vents and seeps. The intention is to identify the maximum scientific return that could be achieved from detailed investigation of the minimum number of sites at...

The dinoflagellate genus Bysmatrum encompasses five epibenthic or tide-pool species and has been characterized by separated anterior intercalary plates. In the present study, we obtained six strains of Bysmatrum from the South China Sea and French Atlantic coast by isolating single cells/cysts from plankton and sediment samples. All strains were examined with light microscopy and scanning electron microscopy. Based on morphological observations, three strains were identified as Bysmatrum subsalsum, characterized by the elongated and rectangular first and a hexagonal second anterior intercalary plate. They differ from each other in the number of sulcal lists and the configuration of the first anterior intercalary plate. One strain was identified as...

Latitudinal gradients in species interactions are widely cited as potential causes or consequences of global patterns of biodiversity. However, mechanistic studies documenting changes in interactions across broad geographic ranges are limited. We surveyed predation intensity on common prey (live amphipods and gastropods) in communities of eelgrass (Zostera marina) at 48 sites across its Northern Hemisphere range, encompassing over 37 degrees of latitude and four continental coastlines. Predation on amphipods declined with latitude on all coasts but declined more strongly along western ocean margins where temperature gradients are steeper. Whereas insitu water temperature at the time of the experiments was uncorrelated with predation, mean annual...

The Biocean database was designed to collate the extremely large volume of data collected from different deep-sea ecosystem studies conducted by Ifremer's department of 'Environnement Profond' (Deep-Sea Environment). This database comes in a 6-application package: 2 of them are used on research vessels to collect operational data, whereas the others are used to link with a core database back on land. The latter are used to: (1) manage taxonomic nomenclature, (2) monitor the identification of faunal collections, (3) fill in chemical analyses results or measurement data files and (4) add or extract data from the database. Biocean was designed to facilitate ecosystem studies in the deep sea. It represents an important new resource for deep-sea ecologists and...

Multiple pygmy blue whale acoustic populations in the Indian Ocean: whale song identifies a possible new population
Provedor de dados: 5
Autores: Leroy, Emmanuelle; Royer, Jean-yves; Alling, Abigail; Maslen, Ben; Rogers, Tracey L.
Blue whales were brought to the edge of extinction by commercial whaling in the twentieth century and their recovery rate in the Southern Hemisphere has been slow; they remain endangered. Blue whales, although the largest animals on Earth, are difficult to study in the Southern Hemisphere, thus their population structure, distribution and migration remain poorly known. Fortunately, blue whales produce powerful and stereotyped songs, which prove an effective clue for monitoring their different ‘acoustic populations.’ The DGD-Chagos song has been previously reported in the central Indian Ocean. A comparison of this song with the pygmy blue and Omura’s whale songs shows that the Chagos song are likely produced by a distinct previously unknown pygmy blue whale...

Alexandrium catenella (group IV) and Alexandrium tamarense (group III) (Dinophyceae) are two cryptic invasive phytoplankton species belonging to the A. tamarense species complex. Their worldwide spread is favored by the human activities, transportation and climate change. In order to describe their diversity in the Mediterranean Sea and understand their settlements and maintenances in this area, new microsatellite markers were developed based on Thau lagoon (France) samples of A. catenella and A. tamarense strains. In this study twelve new microsatellite markers are proposed. Five of these microsatellite markers show amplifications on A. tamarense and ten on A. catenella. Three of these 12 microsatellite markers allowed amplifications on both cryptic...

The brown algal genus Padina (Dictyotales, Phaeophyceae) is distributed worldwide in tropical and temperate seas. Global species diversity and distribution ranges, however, remain largely unknown. Species-level diversity was reassessed using DNA-based, algorithmic species delineation techniques based on cox3 and rbcL sequence data from 221 specimens collected worldwide. This resulted in estimates ranging from 39 to 61 putative species (ESUs), depending on the technique as well as the locus. We discuss the merits, potential pitfalls, and evolutionary and biogeographic significance of algorithmic species delineation. We unveil patterns whereby ESUs are in all but one case restricted to either the Atlantic or Indo-Pacific Ocean. Within ocean basins we find...

Biogeography Revisited with Network Theory: Retracing the History of Hydrothermal Vent Communities
Provedor de dados: 5
Autores: Moalic, Yann; Desbruyeres, Daniel; Duarte, Carlos M.; Rozenfeld, Alejandro F.; Bachraty, Charleyne; Arnaud-haond, Sophie.
Defining biogeographic provinces to understand the history and evolution of communities associated with a given kind of ecosystem is challenging and usually requires a priori assumptions to be made. We applied network theory, a holistic and exploratory method, to the most complete database of faunal distribution available on oceanic hydrothermal vents, environments which support fragmented and unstable ecosystems, to infer the processes driving their worldwide biogeography. Besides the identification of robust provinces, the network topology allowed us to identify preferential pathways that had hitherto been overlooked. These pathways are consistent with the previously proposed hypothesis of a role of plate tectonics in the biogeographical history of...

Of the numerous species, Emiliania huxleyi is considered one of the major calcifiers in the pelagic ocean. There is growing concern that increasing levels of CO2 in the atmosphere and the subsequent acidification of the ocean may disrupt the production of coccoliths. Furthermore, any change in the global distribution and abundance of E. huxleyi relative to non-calcifying groups of phytoplankton (e. g. diatoms) will have important effects on the biogeochemical cycling of carbon and climatic feedbacks. We review different lines of evidence that suggest E. huxleyi is increasingly expanding its...

Circulation patterns in the North Atlantic Ocean have changed and re-organized multiple times over millions of years, influencing the biodiversity, distribution, and connectivity patterns of deep-sea species and ecosystems. In this study, we review the effects of the water mass properties (temperature, salinity, food supply, carbonate chemistry, and oxygen) on deep-sea benthic megafauna (from species to community level) and discussed in future scenarios of climate change. We focus on the key oceanic controls on deep-sea megafauna biodiversity and biogeography patterns. We place particular attention on cold-water corals and sponges, as these are ecosystem-engineering organisms that constitute vulnerable marine ecosystems (VME) with high associated...

Cryptic diversity within the harmful dinoflagellate Akashiwo sanguinea in coastal Chinese waters is related to differentiated ecological niches
Provedor de dados: 5
Autores: Luo, Zhaohe; Yang, Weidong; Leaw, Chui Pin; Pospelova, Vera; Bilien, Gwenael; Liow, Guat Ru; Lim, Po Teen; Gu, Haifeng.
Blooms of the harmful dinoflagellate Akashiwo sanguinea are responsible for the mass mortality of fish and invertebrates in coastal waters. This cosmopolitan species includes several genetically differentiated clades. Four clonal cultures were established by isolating single cells from Xiamen Harbour (the East China Sea) for morphological and genetic analyses. The cultures displayed identical morphology but were genetically different, thus revealing presence of cryptic diversity in the study area. New details of the apical structure complex of Akashiwo sanguinea were also found. To investigate whether the observed cryptic diversity was related to environmental differentiation, 634 cells were obtained from seasonal water samples collected from 2008 to 2012....

Phylogeny and phylogeography of Atlantic oyster species: evolutionary history, limited genetic connectivity and isolation by distance
Provedor de dados: 5
Autores: Lazoski, C.; Gusmao, J.; Boudry, Pierre; Sole-cava, A. M.
The phylogenetic relationships between naturally occurring Atlantic Crassostrea oyster species were inferred through analyses of mitochondrial (cytochrome oxidase subunit I and 16S) and nuclear (second internal transcribed spacer) sequences. We also scored 15 allozyme loci on 422 oysters to study population structuring of C. rhizophorae and C. brasiliana along 9000 km of the Western Atlantic coastline. Despite morphological similarities, C. virginica was genetically more closely related to C. rhizophorae than to C. brasiliana. In contrast, C. paraibanensis was genetically indistinguishable from C. brasiliana, which is probably a junior synonym of the African C. gasar. Significant genetic differentiation between populations of C. rhizophorae and C. gasar...

Patterns of species range evolution in Indo-Pacific reef assemblages reveal the Coral Triangle as a net source of transoceanic diversity
Provedor de dados: 5
Autores: Evans, Sean M.; Mckenna, Caroline; Simpson, Stephen D.; Tournois, Jennifer; Genner, Martin J.
The Coral Triangle in the Indo-Pacific is a region renowned for exceptional marine biodiversity. The area could have acted as a 'centre of origin' where speciation has been prolific or a 'centre of survival' by providing refuge during major environmental shifts such as sea-level changes. The region could also have acted as a 'centre of accumulation' for species with origins outside of the Coral Triangle, owing to it being at a central position between the Indian and Pacific oceans. Here, we investigated support for these hypotheses using population-level DNA sequence-based reconstructions of the range evolution of 45 species (314 populations) of Indo-Pacific reef-associated organisms. Our results show that populations undergoing the most ancient...

Can we generate robust species distribution models at the scale of the Southern Ocean?
Provedor de dados: 5
Autores: Fabri-ruiz, Salomé; Danis, Bruno; David, Bruno; Saucède, Thomas.
Aim Species distribution modelling (SDM) represents a valuable alternative to predict species distribution over vast and remote areas of the ocean. We tested whether reliable SDMs can be generated for benthic marine organisms at the scale of the Southern Ocean. We aimed at identifying the main large‐scale factors that determine the distribution of the selected species. The robustness of SDMs was tested with regards to sampling effort, species niche width and biogeography. Location Southern Ocean. Methods The impact of sampling effort was tested using two sets of data: one set with all presence‐only data available until 2005, and a second set using all data available until 2015 including recent records from campaigns carried out during the Census of...

Autores: Bellan-santini, D; Dauvin, J.
In the world, the Ampelisca genus is constituted by more than 140 species, which are found between 0 to 4000 m depth. Phylogeny, biology and ecology are the most important interest in this genus. The present analysis of new and older collections (E. Chevreux) have permitted to describe 11 new species. 41 species are listed in the north-eastern Atlantic fauna. These are different arguments to think that Ampelisca groups was actually in speciation. Two groups issued from a phenetic analysis are discriminated by their apomorphic levels. More than of the third are endemic species. 21 species are present only in one of the five biogeographic region. 23 species are limited to the continental shelf, 34 live up to the first 1000 meters and 4 are bathyal. 2 species...

Aim To define the major biogeographical regions and transition zones for freshwater fish species. Taxon Strictly freshwater species of actinopterygian fish (i.e. excluding marine and amphidromous fish families). Methods We based our bioregionalization on a global database of freshwater fish species occurrences in drainage basins, which, after filtering, includes 11,295 species in 2,581 basins. On the basis of this dataset, we generated a bipartite (basin‐species) network upon which we applied a hierarchical clustering algorithm (the Map Equation) to detect regions. We tested the robustness of regions with a sensitivity analysis. We identified transition zones between major regions with the participation coefficient, indicating the degree to which a basin...

Autores: Balzano, Sergio; Percopo, Isabella; Siano, Raffaele; Gourvil, Priscillia; Chanoine, Melanie; Marie, Dominique; Vaulot, Daniel; Sarno, Diana.
Seventy-five diatoms strains isolated from the Beaufort Sea (Canadian Arctic) in the summer of 2009 were characterized by light and electron microscopy (SEM and TEM) as well as 18S and 28S rRNA gene sequencing. These strains group into 20 genotypes and 17 morphotypes and are affiliated with the genera Arcocellulus, Attheya, Chaetoceros, Cylindrotheca, Eucampia, Nitzschia, Porosira, Pseudo-nitzschia, Shionodiscus, Thalassiosira, Synedropsis. Most of the species have a distribution confined to the northern/polar area. Chaetoceros neogracilis and Chaetoceros gelidus were the most represented taxa. Strains of C. neogracilis were morphologically similar and shared identical 18S rRNA gene sequences, but belonged to four distinct genetic clades based on 28S rRNA,...

Analyse des déterminants environnementaux de la variabilité du recrutement - approche macroécologique appliquée aux populations exploitées du Nord-Est Atlantique
Provedor de dados: 5
Autores: Brunel, Thomas.
Recruitment - the number of young fishes that integrate each year the exploitable stock¿ has a central importance for stock dynamics. The high temporal variability in recruitment is a result of the environmental influence on survival during early life stages. Understanding the determinism of the influence of environment on recruitment remains one of the most important question in fisheries ecology. The present work aimed at answering some general questions about the influence of environment on fish recruitment using a macroecological approach. The study focused on the exploited fish populations of the Northeastern Atlantic. The first chapter of the thesis makes a review of the different methods used to estimate recruitment, compares recruitment estimates...

Speciation in Cyprinidae of the Iberic Peninsula.
Provedor de dados: 5
Autores: Almaca, Carlos.
Coming from Oriental Asia and Siberia, the Cyprinidae reached the Iberic Peninsula probably at the end of the Oligocene. Their populations bore speciation processes which led to the formation of a fauna rich in endemic species and subspecies. Populations of two of the genera Barbus and Pseudophoxinus reached Northwestern African forming there several endemic species. Concerning the speciation forms, it is probable that the allopatric form, whether by foundation effect or by subdivision, played an important part. Pyrenees and Mediterranean Sea settled probably efficient barriers for the Iberic Cyprinidae isolation. The present geographical repartition of Cyprinidae in Iberic Peninsula suggests that altitude lines and glaciations which reached the north of...

Mammals of the Cosigüina Peninsula of Nicaragua
Provedor de dados: 81
Autores: Genoways,Hugh H.; Timm,Robert M.
Nicaragua's Cosigüina Peninsula, located at the northwestern tip of the country, is one of the most poorly studied biotic regions in Central America. The peninsula has been occupied for millennia because the climate of the region supported human habitation and because of its strategic position along the rich Pacific coast. The combination of long-term occupancy by humans and the cataclysmic eruptions of Volcán Cosigüina have produced a heavily impacted landscape. During the 1960s, the University of Kansas conducted multiyear field surveys of the terrestrial mammals on the peninsula and the adjacent mainland to quantify species diversity, relationships, abundances, habitat use, and reproduction. The mammalian fauna of the peninsula contains at least 39...

Autores: Olson,Storrs L.; Nieves-Rivera,Ángel M.
The greater fishing bat Noctilio leporinus has long been erroneously attributed to Isla de Mona, Puerto Rico, based on specimens from Monos Island, Trinidad. There are no historical specimens from the island but a radius from a late Holocene cave deposit now establishes that the species was once present. Its apparent extinction may be have been caused by human intervention, a factor that should be taken into account in the biogeography of West Indian bats.

We review the known distribution of Monodelphis kunsi from South America and reported nine new localities of occurrence in Mato Grosso do Sul state, southwestern Brazil. These new records fill the gap on geographic distribution of M. kunsi in southwestern Brazil. The species presents wide geographic range including distinct habitats. The lack of studies in southwestern Brazil and the non-utilization of pitfall traps can be the main factors responsible for the lack of knowledge on distribution of small mammal species to this region.

Current perspectives on the evolution of birds
Provedor de dados: 16
Autores: Ericson, P.G.P.
The paper summarizes the current understanding of the evolution and diversification of birds. New insights into this field have mainly come from two fundamentally different, but complementary sources of information: the many newly discovered Mesozoic bird fossils and the wealth of genetic analyses of living birds at various taxonomic levels. The birds have evolved from theropod dinosaurs from which they can be defined by but a few morphological characters. The early evolutionary history of the group is characterized by the extinctions of many major clades by the end of the Cretaceous, and by several periods of rapid radiations and speciation. Recent years have seen a growing consensus about the higher- level relationships among living birds, at least as...

Gymnophthalmus cryptus spec. nov. is described and illustrated on the basis of males and females collected in the Territorio Federal Amazonas, southern Venezuela. Some details on ecology and distribution are also presented. The females of G. cryptus are very similar to the unisexual Gymnophthalmus underwoodi, which also occurs in the Guianan Region. In fact, G. cryptus is one of the best candidates for future genetic research to determine whether it is the missing ancestor of G. underwoodi, a parthenogenetic species of hybrid origin (G. speciosus x G. spec.?). Two other series of previously unreported species of Gymnophthalmus from Venezuela are also discussed.

A Miocene perspective on the evolution of the Amazonian biota
Provedor de dados: 16
Autores: Wesselingh, F.P.; Salo, J.A.
Between c. 23 and 8 Ma, western Amazonia was occupied by the vast Pebas long-lived lake/wetland system. The Pebas system had a variety of influences over the evolution of Miocene and modern Amazonian biota; it formed a barrier for the exchange of terrestrial biota, a pathway for the transition of marine biota into freshwater Amazonian environments, and formed the stage of remarkable radiations of endemic molluscs and ostracods. The lithological variation of the Pebas Formation has furthermore enhanced edaphic heterogeneity in western Amazonia, sustaining present-day high terrestrial diversity in the region.

An account is given of 13 species of freshwater planarians from the family Dugesiidae, based on samples from new localities in New Zealand and Australia; these include four newly described and one problematic species. In the case of three species, the material described represents the second series of specimens available since the material used in the original descriptions of these species, as a result of which our understanding of the morphology of the animals can be expanded. In other cases, the new material also contributed to a more detailed understanding of the anatomy of the species.

Phylogeny and biogeography of midwife toads (Alytes, Discoglossidae): a rebuttal
Provedor de dados: 16
Autores: Arntzen, J.W.; García-París, M.
Three competing phylogenetic hypotheses for the genus Alytes (midwife toads) are evaluated. Based on quantitative coding of protein characters the most parsimonious solution shows a sister taxon relationship for Alytes dickhilleni and A. muletensis. The alternatives in which A. obstetricans has its sister group in either A. dickhilleni or A. muletensis lack support. Using calibrations derived from protein evolutionary rates, the vicariant events giving rise to A. obstetricans and the lineage leading to the A. muletensis and A. dickhilleni clade and the subsequent splitting between A. muletensis and A. dickhilleni cannot be placed much earlier than the Miocene-Pliocene boundary. Biogeographical scenarios invoking an earlier time of divergence should be...

The anatomy and phylogeny of the African land snail Limicena Connolly, 1925 (Pulmonata: Cerastidae)
Provedor de dados: 16
Autores: Mordan, P.
An investigation of the anatomy of Limicena confirms its position as a monotypic genus in the Cerastidae. Phylogenetic analysis places Limicena as the most plesiomorphic member of a clade characterised by a pseudosigmurethrous excretory system, the more advanced members of which are Rhachistia, Amimopina and Edouardia. Its position at the base of such a widely dispersed, advanced clade with apparently xerophilic adaptations lends support to a dispersalist hypothesis for the extra-Afrotropical distribution of the Cerastidae.

The biogeography and extinction of megapodes in Oceania
Provedor de dados: 16
Autores: Steadman, D.W.
The arrival of prehistoric peoples in Oceania over the past several millennia resulted in the extinction of many species and populations of megapodes. Before these anthropogenic losses, species of megapodes ranged across Melanesia, Western Polynesia, and much of Micronesia. Island groups that lack megapodes today but were inhabited by them in the past include New Caledonia, Fiji, the Ha`apai Group and `Eua (Tonga), Samoa, Niue, and Pohnpei. The extinct megapodes varied in size from a tiny, quail-like species of Megapodius in Tonga to the large, flightless Sylviornis of New Caledonia. Remote Tongan islands as small as 13 km2 were able to sustain three species of Megapodius before human impact, thus calling into question the validity of using modern species...

A taxonomic survey of seaweeds from Eritrea
Provedor de dados: 16
Autores: Ateweberhan, M.; Prud’homme van Reine, W.F.
A survey of seaweeds was made in Eritrea in December 1995 and January 1996 on some islands of the Dahlak Archipelago and the surroundings of the port town of Massawa. During our study 101 specific and infraspecific taxa were identified, including 26 Chlorophyta, 20 Phaeophyta and 55 Rhodophyta. The survey resulted in 36 new records for Eritrea (11 Chlorophyta, 7 Phaeophyta and 18 Rhodophyta). Of these Eritrean records, 26 are new for the Red Sea (5 Chlorophyta, 4 Phaeophyta and 17 Rhodophyta). Comparison of records of seaweeds from localities in Eritrea to those from other localities in Eritrea as well as from other coasts of the western Indian Ocean have revealed that the regional distribution of seaweeds in the Red Sea is very patchy and that generally...

Phylogenetic biogeography of Euphrasia section Malesianae (Orobanchaceae) in Taiwan and Malesia
Provedor de dados: 16
Autores: Wu, M.-J.; Huang, T.-C.; Huang, S.-F.
Species of Euphrasia are distributed in both hemispheres with a series of connecting localities on the mountain peaks of Taiwan and the Malesian region including Luzon, Borneo, Sulawesi, Seram and New Guinea. Two hypotheses are proposed to explain this distribution pattern. The Northern Hemisphere might have been the centre of origin or the Southern Hemisphere. This study aims to reconstruct the core phylogeny of Euphrasia in the connecting areas and tries to identify the migratory direction of Euphrasia in Taiwan and Malesia. The phylogeny of Euphrasia, including sections Euphrasia, Malesianae and Pauciflorae, is reconstructed with the chloroplast molecular markers rps2 gene, trnL intron and trnL-trnF intergenic spacer. The results suggest that the...

A taxonomic, phylogenetic and biogeographic study of the genus Acanthophora (Rhodomelaceae, Rhodophyta)
Provedor de dados: 16
Autores: Jong, Yde S.D.M. de; Hitipeuw, Creusa; Prud’homme van Reine, Willem F.
A cladistic analysis, based on a taxonomic revision is carried out for 7 Acanthophora species using 19 characters. Hypotheses on species affinities are based primarily on morphological characters. Because most species show only few distinctive characters, emphasis was placed on features of spine development, either in relation to vegetative or to reproductive structures. Global distribution of 7 Acanthophora species: viz. A. aokii, A. dendroides, A. muscoides, A. nayadiformis, A. pacifica, A. ramulosa, and A. spicifera, shows a discontinuous pattern. Although widely distributed species are present (A. muscoides and A. spicifera), a disjunct distribution of other species occurs in the Pacific (A. aokii), Indian Ocean (A. dendroides), East-Atlantic region...

Autores: Gielis, C.
The genera of the superfamily Pterophoroidea are redescribed. Three new genera are described: Dejongia, Stockophorus and Shafferia. The characters of the genera and their states are translated into a data matrix. A majority rule consensus tree composed with PAUP serves as a basis for a phylogenetic analysis. A cladogram, representing the views of the author, based on the data acquired, is presented with argumentation. The evaluation of the characters is discussed. A new subfamily is erected, the Deuterocopinae. The Pterophorinae are redefined. The Platyptiliinae are synonymized with the Pterophorinae. The Macropiratidae, considered by Minet (1991) a subfamily or a genus of the Pterophoridae, has been raised to family rank, and is placed as the sister group...

Provedor de dados: 16
Autores: Fiers, F.
So far, only three species are known in the laophontid genus Loureirophonte Jakobi. In the present contribution five new species are described, and two species formerly attributed to other laophontid genera (Paraiaophonte subterranea Lang and Laophonte cesareae Por), are allocated to Loureirophonte. A redescription of L. cesareae, based on type-material, is included. Relying on the increased understanding of loureirophontid morphology, the diagnoses of L. catharinensis, type-species of the genus, and L. paranaensis are amended. Finally, three species-groups are defined within the genus: the catharinensisgroup, the cesareae-group and the subterranea-group.

Comparative reproductive anatomy in the South African giant land snails (Gastropoda: Pulmonata: Achatinidae)
Provedor de dados: 16
Autores: Mead, A.R.
The history and current taxonomic status of 62 nominal taxa are revised that have been associated in the literature with the subgenus Tholachatina Bequaert, 1950, of genus Archachatina Albers, 1850, and the genus Cochlitoma Férussac, 1821, in the land snail family Achatinidae Swainson, 1840. Tangible, reliable characters have been found in the detailed features of the reproductive anatomy in this family. The results of comparative anatomical study convincingly reflect phylogeny in contrast to the comparative study of only the shell characters. This latter more strongly reflects the effects of the intrinsically variable environment over time. In the present study, both sets of characters are needed to refine identification.

Ten species added to the genus Aedeastria De Boer, 1990, with the description of eight new species and notes on the taxonomy and biogeography (Homoptera, Tibicinidae)
Provedor de dados: 16
Autores: Boer, A.J. de.
A new concept is proposed for the cicad genus Aedeastria De Boer, 1990, so that ten species can be added, bringing the total number of species to twelve. Of these ten species added to the genus, two (A. latifrons (Blöte) and A. digitata (Blöte)) are redescribed and transferred from Baeturia Stål, while eight species (A. bullata, A. cheesmanae, A. dilobata, A. hastulata, A. kaiensis, and A. moluccensis, A. obiensis, A. waigeuensis) are described as new. A key to the males of Aedeastria is presented. Aedeastria belongs to a group of Australian and New Guinean genera, defined earlier as the “Baeturia and related genera complex” and is very closely related to the genus Thaumastopsaltria Kirkaldy of that complex.

Cladistics and biogeography of the assassin bug genus Rasahus Amyot &amp; Serville (Heteroptera: Reduviidae: Peiratinae)
Provedor de dados: 16
Autores: Morrone, J.J.; Coscarón, M. del C.
The assassin bug genus Rasahus Amyot &amp; Serville (Heteroptera: Reduviidae: Peiratinae) comprises 26 Neotropical species. A cladistic analysis of the genus was carried out using 63 characters from external morphology, body vestiture, and male and female genitalia, with the species considered as terminal taxa. The analysis yielded 149 equally parsimonious cladograms, each with 206 steps, CI = 0.35, and RI = 0.60; the successive weighting procedure resulted in eight cladograms (CI = 0.79 and RI = 0.91). In the strict consensus cladogram, two major clades are delimited: one comprising the species R. rufiventris, R. hamatus, R. arcitenens, R. arcuiger, R. amapaensis, R. thoracicus, R. biguttatus, R. argentinensis, R. limai, R. grandis, and R. angulatus; and...

Notes on macroglossine bats from Sulawesi and the Moluccas, Indonesia, with the description of a new species of Syconycteris Matschie, 1899 from Halmahera (Mammalia: Megachiroptera)
Provedor de dados: 16
Autores: Rozendaal, F.G.
A recent collection of bats from northern Sulawesi (Celebes), Halmahera and Bacan (Batjan), Indonesia, contains representatives of three macroglossine genera. A specimen of Eonycteris rosenbergii (Jentink, 1889) from northern Sulawesi — a species previously known only from the immature type specimen — together with an additional, previously unreported specimen confirms the diagnostic value of the absence of the third lower molar. The validity of this taxon has been questioned by several authors, who suggested that E. rosenbergii is based on an anomalous specimen of E. spelaea (Dobson, 1871). Other material of Eonycteris from Sulawesi, referable to spelaea, is discussed, with the first record for the island of Muna (Moena), and comparative notes are given...

The study of twenty-nine oligochaete samples collected in 1996 by J. H. Stock and J. J. Vermeulen (University of Amsterdam), in the Sultanate of Oman, allowed us to draw up an initial inventory of the freshwater oligochaete fauna of the Arabian peninsula, a fauna totally unknown until now. The 147 specimens examined belong to nine species of four families: Phreodrilidae, Naididae, Tubificidae and Enchytraeidae. The Phreodrilidae (2 species) represent more than half of the total specimens; whilst the rest belong mainly to the Naididae. Two new species of Phreodrilidae (Antarctodrilus arabicus n. sp. and Phreodrilus stocki n. sp.) are described.

Avian biogeography on western Indian Ocean islands: eustatic sea levels, geological events and anthropogenic changes
Provedor de dados: 16
Autores: Hume, J.P.
The south-western Indian Ocean islands, excluding the microcontinent of Madagascar, are geologically complex and diverse. They have been subject to drastic sea level changes, volcanic events and anthropogenic changes, all of which have contributed to confuse understanding of their avian biogeography. An array of factors have affected these avifaunas, based on palaeontological, historical and molecular evidence,which together have shown that avian biogeography is not congruent with the relative age and size of the islands.

We describe the vegetation of Kwerba, in the foothills of the Foja Mountains in the Mamberamo Basin of West Papua, Indonesia. Few surveys have been carried out in this remote area of Western New Guinea. Working in collaboration with local people we made 15 plots, 10 in primary forest, 3 in secondary forest and 2 in gardens. A total of 487 morpho-species were distinguished, of which 32 % (156) did not match any herbarium specimens or published reference. Tree densities (598 ± 136/ha) are similar to lowland forests elsewhere, but mean stem sizes (22 ± 1 cm dbh and 21 ± 2 m height for trees over 10 cm dbh) appear small. Numbers of tree species per plot (22 ± 4, of 40 stems recorded) are unremarkable, but levels of endemism are potentially high with many of...

Names of Tapeinochilos (Costaceae) in Wallacea
Provedor de dados: 16
Autores: Poulsen, A.D.; Gideon, O.G.; Ardiyani, M.
Four species of Tapeinochilos have been described from material collected in Wallacea. We designate the lectotype of the genus, T. pungens, which was synonymized with T. ananassae in 1917 and add here T. teysmannianus as another synonym. The type of T. koordersianus from Sulawesi has been rediscovered at Herbarium Bogoriense and is identified as Etlingera heliconiifolia (Zingiberaceae), the combination of which is published here. After establishing that T. koordersianus applies to a species of Etlingera, there is no evidence that any species of Tapeinochilos occurs in the island of Sulawesi; the westernmost presence of the genus being in the Sula Islands represented by T. ananassae, the only species thus presently occurring in Wallacea.

The viridis group is proposed for a supposedly monophyletic group of seven New Guinean species of the cicada genus Baeturia Stål, 1866. Three species (B. brongersmai Blöte, B. rufula Blöte, and B. viridis Blöte) are redescribed and four species (B. furcillata, B. karkarensis, B. lorentzi, and B. turgida) are described as new to science. A key to the males is provided. The phylogenetic position of the viridis group within the genus Baeturia is discussed. The distribution of shared characters suggests a subdivision of the group into two subgroups. One subgroup is restricted to southern and western Irian Jaya, while the other is distributed along the coastal mountain ranges of northern New Guinea, including Karkar Island.

Contemporary distributions of Panurginus species and subspecies in Europe (Apoidea: Andrenidae: Panurginae)   The largest number of Old World Panurginus Nylander, 1848 species is distributed in the West- Palaearctic. The genus is absent in Africa and rather rare in the East-Palaearctic. Warncke (1972, 1987), who is the main author treating Palaearctic Panurginae in the last decades, subdivided Panurginus into a small number of species, including two principal taxa admitting for each a very large number of subspecies: Panurginus brullei (Lepeletier, 1841) and Panurginus montanus Giraud, 1861. Following recent works, the two latter are in fact complexes of closely related species. In the West-Palaearctic context, distributions of certain species implied in...

Provedor de dados: 16
Autores: Essink, K.; Kleef, H.L.
A new record of the North American spionid polychaete Marenzelleria viridis (Verril, 1873) is reported from the Ems Estuary. The species was first found in 1983. From 1983 to 1986 densities increased to a few thousands per m2 while densities of another polychaete, Nereis diversicolor decreased. Juveniles showed peak densities of c. 19000 m2 in muddy sediments. Adults preferred sandy sediments. In Europe M. viridis was recorded recently also in other estuaries: Tay and Forth (Scotland), Weser and Elbe (Fed. Rep. of Germany). There is no reliable clue to the cause of its appearance in North Sea estuaries.

Autores: Koenemann, Stefan; Holsinger, John R.
Bactrurus Hay is a relatively small generic group that inhabits caves and related groundwater habitats in parts of eastern and central USA. Two field trips, conducted in the spring of 1999, yielded important new locality records that give us a better knowledge of the distribution of the genus. The examination of fresh samples as well as older collection material has resulted in descriptions of four new species. Based on these descriptions and redescriptions of three previously known species, the taxonomy of the genus is revised. In addition, a phylogenetic analysis using morphological data is employed to examine the relationship of Bactrurus to 12 selected crangonyctid taxa, including its potential sister genus Stygobromus Cope.

Aspects of the evolution and biogeography of stygobiontic Isopoda (Crustacea: Peracarida)
Provedor de dados: 16
Autores: Wägele, Johann-Wolfgang.
The evolution of the stygobiontic isopods is discussed correlating the phylogenetic system with biogeography. All stygobiontic isopods probably are derived from remote marine ancestors. The colonization of subterranean aquatic biotopes occurred in two ways: (1) via the coastal groundwater in the case of the Microparasellidae, Gnathostenetroididae, Stenetriidae, and in Cyathura (Stygocyathura), (2) in most families, however, via epigean freshwater ancestors. Ancient freshwater isopods that must already have existed before the Cretaceous and whose stygobiontic phylogenetic lines partly must have existed before the opening of the Atlantic are the Aselloidea, Calabozoida, Phreatoicidea, and probably also the Protojaniridae. In the course of Cretaceous and...

Amphi-Atlantic distribution of the subterranean amphipod family Metacrangonyctidae (Crustacea, Gammaridea)
Provedor de dados: 16
Autores: Jaume, Damià; Christenson, Keith.
Members of the strictly stygobiont, continental subterranean amphipod family Metacrangonyctidae are reported for the first time outside the Old World. Two new species of Metacrangonyx are described from two widely separated localities in the Dominican Republic (Hispaniola), one facing the Caribbean and the other the Atlantic ocean. The discovery of metacrangonyctids in the western Atlantic suggests that they are an ancient subterranean lineage tied to the shores of the Tethys belt, and thus weakens previous biogeographic arguments raised to favour their separate and independent family status with respect to the Hadziidae. The discovery in the Mediterranean of marine populations of metacrangonyctids is reported as well, and both findings are used to test...

First Indonesian record of Fungiacava eilatensis Goreau et al., 1968 (Bivalvia: Mytilidae), endosymbiont of Fungia spp. (Scleractinia: Fungiidae)
Provedor de dados: 16
Autores: Hoeksema, B.W.; Achituv, Y.
The mytilid bivalve Fungiacava eilatensis Goreau, Goreau, Neumann &amp; Yonge, 1968, previously mistakenly referred to as F. eilatensis Soot-Ryen, 1969, is reported for the first time from Indonesia. It lives as an obligate endosymbiont of mushroom corals, particulary Fungia spp., reef-dwelling corals restricted to the tropical Indo-Pacific. Notes are given on its association with different host species, its habitat, its biogeography, and its possible competition with endosymbiotic gastropods belonging to the genus Leptoconchus (Coralliophilidae).

Streptaxidae (Mollusca: Gastropoda: Pulmonata) of the Seychelles Islands, Western Indian Ocean
Provedor de dados: 16
Autores: Gerlach, J.; Bruggen, A.C. van.
The taxonomy of the species of the terrestrial carnivorous snail family Streptaxidae of the Seychelles archipelago is reviewed with the exception of the three species of the genus Priodiscus (vide Gerlach, 1995). All 18 species are restricted to the northern, granitic islands. This paper describes 15 species, including two new genera (Silhouettia and Careoradula), and four new subspecies (Edentulina dussumieri reservae, E. d. silhouettae, E. d. praslina, Stereostele nevilli parvidentata). The nominal taxon Streptaxis (Imperturbatia) constans var. silhouettae is raised to species level to become the type species of the new genus Silhouettia. The type species of Careoradula is Streptaxis (Imperturbatia) perelegans. Anatomical descriptions and figures are...

On Idyla pelobsoleta spec. nov. (Mollusca: Gastropoda Pulmonata: Clausiliidae), and insularity in the molluscan fauna of the highest parts of the Parnon Oros, Peloponnisos, Greece
Provedor de dados: 16
Autores: Gittenberger, E.
An annotated check-list concerning the molluscan fauna of the two highest peaks in the Parnon Oros, Peloponnisos, Greece, is provided, with emphasis on distributional data. The localities reported upon are situated only 15 km apart. Nevertheless, they are quite different in species composition. From one of these isolated peaks and from a second locality in another mountain range, Idyla pelobsoleta spec, nov., is described. The insular character of the two Parnon peaks, especially with regard to their clausiliid species, is emphasized.

Provedor de dados: 16
Autores: Meij, S.E.T. van der; Visser, R.R.
During the Snellius expedition (1929-30) in eastern Indonesia and the Philippines, a large collection of Acropora corals was made. This collection is comprised of roughly 700 specimens, many of which remain unidentifi ed. In this paper we discuss species of the Acropora humilis group collected during the expedition and compare the records with the known distribution ranges in Indonesia. New records are found, most notably for Acropora multiacuta, A. retusa and A. fastigata.

Evidence for the validity of Protatlanta sculpta (Gastropoda: Pterotracheoidea)

Autores: Wall-Palmer, D.; Burridge, A.K.; Peijnenburg, K.C.T.A.; Janssen, A.; Goetze, E.; Kirby, R.; Hart, M.B.; Smart, C.W.
The genus Protatlanta is thought to be monotypic and is part of the Atlantidae, a family of shelled heteropods. These microscopic planktonic gastropods are poorly known, although research on their ecology is now increasing in response to concerns about the effects of ocean acidification on calcareous plankton. A correctly implemented taxonomy of the Atlantidae is fundamental to this progressing field of research and it requires much attention, particularly using integrated molecular and morphological techniques. Here we use DNA barcoding, shell morphology and biogeography to show that the genus Protatlanta includes at least two valid species in the Atlantic Ocean. Protatlanta souleyeti and Protatlanta sculpta were found to be separate species, with...

Cryptic variation and recent bipolar range expansion within the Stumped-Toed Gecko Gehyra mutilata across Indian and Pacific Ocean islands
Provedor de dados: 16
Autores: Rocha, S.; Ineich, I.; Harris, D. James.
With an impressively wide distribution, Gehyra mutilata is present on almost all Indian and Pacific Ocean islands and in large regions of Southeast Asia and Indonesia. Mitochondrial sequence data (~500 bp) from individuals covering large parts of its (mainly insular) distribution reveals deep cryptic variation and strong geographic structure, with two well differentiated lineages. Molecular data also reveals that the wide Indian and Pacific insular distribution of Gehyra is very recent and, at least across the Indian Ocean islands, most probably the result of human-aided dispersal, as no variation within this lineage was found. Further research is needed to determine geographic patterns of variation across Southeast Asia, the level of genetic variation,...

Autores: Zhu, Hua.
Two populations from Mount Kinabalu, Borneo, are recognised as two new subspecies of Lasianthus inodorus Blume (Rubiaceae), which occurs in montane habitats in mainland Southeast Asia, Sumatra and Java. The species and its subspecies are considered to compose a particular taxonomic group in the genus. Ecology and biogeography of the species group are discussed with the historical explanation of the tectonic history of Cenozoic Southeast Asia. The example strongly supports the concept of floristic connections between Malesia and mainland Southeast Asia.

The sections Azorelloida, Neoandina, and Paramensia of Geranium, all of them from the Andes, are taxonomically revised. Fruits with the ‘seed ejection-type’ dispersal have been found in all species, which allows classifying them within subg. Geranium. The sections Azorelloida and Paramensia consist of one and two species respectively, while section Neoandina comprises 24 taxa. Prior to this revision, the stemless species of Geranium from the Andes have been considered to belong to sect. Andina. Geranium sessiliflorum (type of Geranium sect. Andina), however, should be included in sect. Chilensia. Therefore, recently a new sect. Neoandina has been described to include most of the sect. Andina species (Aedo, 2000).

An unusual sea anemone from slope depths of the tropical west Pacific: range extension and redescription of Isactinernus quadrilobatus Carlgren, 1918 (Cnidaria: Actiniaria: Actinernidae)
Provedor de dados: 16
Autores: Fautin, D.G.; Hartog, J.C. den.
The sea anemone species Isactinernus quadrilobatus Carlgren, 1918, and Synactinernus flavus Carlgren, 1918, which were described in new monotypic genera from few specimens collected in southern Japan, are synonymized, based on many more specimens from the South Pacific. As well as the geographic range, the depth range of this species has been extended to 110-700 m. The species had been distinguished primarily on whether the oral disc had four lobes (I. quadrilobatus) or eight (Synactinernus flavus) – we conclude their number is largely related to size of the animal. Other features that Carlgren had used to differentiate the genera (and species) are inconsistently present and do not correlate with lobe number.

This study of Chthonerpeton indistinctum (Reinhardt &amp; Lütken, 1861) considers 25 morphometric characters, teeth-counts and sex, based on 96 specimens. A multivariate analysis of characters and comparisons of geographically arranged samples is carried out by graphic and statistical methods. No trends in geographical variation were found. Subsequently a redescription of the species is presented, including measurements and counts. Sexual dimorphism was observed for four characters related to the cloacal region. The results are discussed and compared with previous reports. Character-variation is also studied. Primary annuli counts show very low variation; sample variation profiles were similar for the remaining characters. A revision of biological data...

Ingolfiellidea (Crustacea, Malacostraca, Amphipoda): a phylogenetic and biogeographic analysis
Provedor de dados: 16
Autores: Vonk, Ronald; Schram, Frederick R.
The suborder Ingolfiellidea currently consists of 39 named species. An historical overview is presented and phylogenetic and biogeographic analyses are made. The result of the phylogenetic analysis suggests the definition of two new genera within an African freshwater group, namely Paraleleupia n. gen. and Proleleupia n. gen. Re-examination of a supposedly Italian relict species, Metaingolfiella mirabitis, with the aid of SEM techniques reveals a half-fusion of the head region with the first pereionite. The issue of the function of the ‘eyelobe’ is addressed and an explanation presented after examining with SEM such lobes in different species. Furthermore, additional descriptions are given based on the type-material of Metaingolfiella mirabilis,...

Three new sympatric species of remipede crustaceans, Speleonectes tanumekes, Speleonectes parabenjamini and Speleonectes minnsi, are described from an anchihaline cave on Great Exuma Island in the central Bahamas. Speleonectes tanumekes is a comparatively long and slender species distinguished by the largest number of trunk segments found in remipedes to date. Speleonectes parabenjamini is morphologically closely related to Speleonectes benjamini, but differs from the latter species by several distinct autapomorphies. Speleonectes minnsi is characterized by comparatively robust maxillules. The occurrence of three sympatric species is a remarkable record for the Remipedia adding to a total of 10 sympatric taxa.

Phylogeny and biogeography of midwife toads (Alytes, Discoglossidae): a reappraisal
Provedor de dados: 16
Autores: Altaba, Cristian R.
The allozyme data base of Arntzen &amp; García-París (1995) on midwife toads (Alytes, Discoglossidae) is reanalysed considering each locus as a discrete character. The phylogeny thus inferred differs from the one obtained with genetic distances in the position of A. dickhilleni from the Betic region – it appears that its sister species is the widespread A. obstetricans, not the Mallorcan endemic A. muletensis. This phylogenetic hypothesis agrees with the taxonomic treatment of the genus based on morphology. A testable biogeographic hypothesis is proposed to account for the diversification of midwife toads in Iberia and the Balearics. The postulated underlying geological changes were the spread of inland saline lakes that divided Iberia (16 mY B.P.), the...

In order to elucidate the properties and placement of several undescribed sequestrate taxa in the group and to reveal the evolutionary history of Rossbeevera and its allies, we conducted phylogenetic analyses based on three nuclear (ITS, nLSU, EF-1α) and two mitochondrial DNA loci (ATP6 and mtSSU) as well as precise morphological observations. Phylogenetic analyses of three nuclear loci suggest a complex evolutionary history with sequestrate fruiting bodies present in several clades, including a previously unrecognized sister clade to Rossbeevera. Here we propose a new sequestrate genus,...

New hypogean cyclopoid copepods (Crustacea) from the Yucatán Peninsula, Mexico
Provedor de dados: 16
Autores: Fiers, Frank; Reid, Janet W.; Iliffe, Thomas M.; Suárez-Morales, Eduardo.
Four previously unknown hypogean species of cyclopoid copepods were collected in cenotes and wells of the Yucatán Peninsula, Mexico. Diacyclops chakan sp. n. and D. puuc sp. n. differ from their congeners in combining 3-segmented swimming legs, 11-segmented antennules, and legs 1-4 endopodite segment 2 all with 2 setae. Species of Diacyclops rarely occur in tropical regions, and the Diacyclops described here are only the second and third species recorded from Mexico. The benthic D. puuc was found in the large underground reservoir of a cenote. Diacyclops chakan was encountered in such large open subterranean water basins, but more frequently and abundantly in wells. The two Mesocyclops species, M. chaci sp. n. and M. yutsil sp. n., most closely resemble...

Contribution to the knowledge of the Proseriata (Platyhelminthes: Seriata) from eastern Australia. II. Genera Pseudomonocelis Meixner, 1943 and Acanthopseudomonocelis n. g
Provedor de dados: 16
Autores: Curini-Galletti, Marco; Cannon, Lester.
Two monocelid species with simplex copulatory bulbs and postpharyngeal ovaries have been found in E. Australia. One of them presents a combination of characters not found in any of the known genera of the Monocelididae, and the new genus Acanthopseudomonocelis is proposed for it. The new genus is characterized by the presence of four stylet-bearing accessory organs and by an internal vagina; it is related to Pseudomonocelis. The other species, Pseudomonocelis schockaerti n. sp., is characterized by a complex bursa-vagina system, and by a highly muscular penial organ and male antrum. It is closely related to P. pardii Schockaert &amp; Martens, 1987, from Somaliland. Two possibly additional species of the genus Pseudomonocelis, not found in a mature stage,...

Autores: Erséus, Christer.
Seven species of Tubificidae are recorded from the Canary Islands, viz. Heterodrilus amplus n. sp., Coralliodrilus leviatriatus Erséus, 1979, Limnodriloides agnes Hrabĕ, 1967, L. janstocki n. sp., Aktedrilus cuneus Erséus, 1984, A. parvithecatus (Erséus, 1978), and Tubifex tubifex (Müller, 1774); the two latter taxa are reported also from the Cabo Verde Islands. All taxa except T. tubifex are marine and there is no evidence of endemism in the freshwater oligochaete fauna of these islands. Heterodritus amplus has short, spindle-shaped, heavily muscular atria; they are morphologically unique within the genus. Limnodriloides janstocki has modified spermathecal setae; it is distinguished from similar species by its long atrial ducts and deep, elaborate...

Flying high: on the airborne dispersal of aquatic organisms as illustrated by the distribution histories of the gastropod genera Tryonia and Planorbarius
Provedor de dados: 16
Autores: Wesselingh, F.P.; Cadée, G.C.; Renema, W.
The actual and fossil distribution patterns of the aquatic gastropod genera Tryonia and Planorbarius indicate that avian dispersal was an important dispersal mechanism in the geological past. Combining the distribution histories of these genera with ecological data on modern relatives provides insights into the process of dispersal of aquatic taxa in general. Avian dispersal of aquatic taxa is facilitated by a variety of factors, including mass occurrence in resting/foraging places of migrating birds, ways to attach to the birds and to overcome desiccation during flight, as well as easy reproduction from a single specimen when introduced into a new habitat. The uncertain taxonomical status of aquatic organisms, as well as biased preservation and sampling,...

Autores: Heilmann-Clausen, J.; Christensen, M.; Frøslev, T.G.; Kjøller, R.
Based on molecular and morphological data we investigated the taxonomy and phylogeny of the ectomycorrhizal genus Tricholoma in northern Europe. Our phylogenetic tree confirmed the presence of at least 72 well circumscribed species within the region. Of these, three species, viz. T. boreosulphurescens, T. bryogenum and T. ilkkae are described as new to science, based on morphological, distributional, ecological and molecular data. Several other terminal branches represent putative cryptic taxa nested within classical species or species groups. Molecular type studies and/or designation of sequenced neotypes are needed in these groups, before the taxonomy can be settled. In general our phylogenetic analysis supported previous suprageneric classification...

Provedor de dados: 16
Autores: Yacoubi-Khebiza, M.; Boulanouar, M.; Coineau, N.
The interstitial stygobiotic isopods of the genus Microcharon (Crustacea) are diversified in Morocco. A new species, M. ourikensis, is described. The new species shows some original characters for this genus: large size, strong elongation in the first male pleopod exopodal inner lobe, 5-dentate mandibular pars incisiva, and 5 spines on the last mandibular palp segment. The species is a member of the Ibero-Maghrebin messoulii group. It is an endemic representative of the Ourika valley groundwater in the Moroccan High Atlas. It derives from a littoral marine ancestor which could have colonized the continental subterranean water during Turonian or Senonian Tethyan regressions.

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...

Biogeography of Mindoro mosses
Provedor de dados: 16
Autores: Linis, V.C.
The moss flora of Mindoro Island was updated based on the 2004–2006 expeditions conducted by the author. The island’s moss flora now consists of 282 species in 128 genera and 39 families, which is higher than Palawan but far less than those of Luzon and Mindanao. Generally, the flora is most abundant in the eastern rainy part of the island, especially along mid-elevations on the east-facing slope of the central mountain range in the transition zone between montane and mossy forests. Moss diversity is also greater in riverine forests than in inland forests at low elevations. Only three moss taxa, Rhaccocarpus alpinus, Dicranoloma daymannianum and Distichophyllum noguchianum, have their Philippine range restricted to the island. Distichophyllum noguchianum...

Diversity and systematics of the sequestrate genus Octaviania in Japan: two new subgenera and eleven new species
Provedor de dados: 16
Autores: Orihara, T.; Smith, M.E.; Shimomura, N.; Iwase, K.; Maekawa, N.
The sequestrate fungi of Japan, including truffle and truffle-like fungi, have not been well characterized but are potentially diverse. We investigated the diversity and phylogeny of Japanese Octaviania specimens using a multifaceted approach including scanning and transmission electron microscopy as well as analysis of nuclear ribosomal DNA (ITS and LSU) and EF-1α (tef1) sequences. Phylogenetic analyses indicate that the genus Octaviania is divided into three major clades, and that there are at least 12 species-level lineages in Japan. Accordingly, we describe two new subgenera, Parcaea and Fulvoglobus, and eleven new species. Subgenus Parcaea accommodates four highly divergent, but macromorphologically almost indiscernible cryptic species. We discuss not...

Systematics, Phylogeny and Biogeography of the chiefly Afromontane Genus Chondrolepis Mabille (Lepidoptera : Hesperiidae)
Provedor de dados: 16
Autores: Jong, R. de.
The five known species of the African genus Chondrolepis Mabille are extensively described and figured and two new species are added. Keys are given to the males and females separately. Most species are restricted to montane habitats, mainly in East Africa. Based on their phylogeny the geographic history of the species is analyzed. It is concluded that the distribution agrees with the predictions to be derived from the hypotheses that montane forests were very much restricted during the last Glacial Period of the Northern Hemisphere, later on becoming more widespread than at present, and that the contact between the Cameroun highlands and the highlands of East Africa was through species that temporarily lived in the intervening lowland forests and not...

Post-glacial dispersal strategies of Orthoptera and Lepidoptera in Europe and in the Carpathian basin
Provedor de dados: 16
Autores: Varga, Z.
Post-glacial dispersal strategies of Orthoptera and Lepidoptera in Europe and in the Carpathian basin   Ecologically transitional regions are characterised by high species diversity due to the overlap of species with different geographical origins caused by dispersal processes along gradients, e.g. the overlap of species belonging to different zonobiomes. The overlap of azonal communities along shortdistance gradients results in the organisation of community-complexes and landscape mosaics connected by habitat ecotones characterised by overlap of several faunal types, like Mediterranean, Balkanic, Siberian, Ponto-Caspian, Ponto-Pannonian, Turano-Eremic and Xeromontane elements in the Pannonian forest-steppe complexes.

Provedor de dados: 16
Autores: Pinto da Motta Amado, Maria Auxiliadora; Ho, Ju-Shey; Falavigna da Rocha, Carlos Eduardo.
Nineteen genera are currently considered valid in the Ergasilidae. A cladistic analysis was conducted on these genera and the five genera composing the closely allied Vaigamidae. Nineteen morphological characters were selected and polarized using Anthessius (Anthessiidae) as the outgroup. The most parsimonious cladogram (tree length = 60, Consistency Index = 0.50, Retention Index = 0.71), obtained through the use of the BB command in Hennig 86, is composed of eight major clades, with the five vaigamid genera composing the most derived clade.

Aglaia elaeagnoidea is the most widespread and one of the more morphologically diverse complex species in the largest genus of the mahogany family (Meliaceae, Sapindales). We performed maximum parsimony, maximum likelihood and Bayesian analyses (nuclear ITS rDNA) to estimate genetic relations among samples of Aglaia elaeagnoidea, and their phylogenetic position within Aglaia (more than 120 species in Indomalesia, Australasia, and the Pacific islands). Based on 90 accessions of Melioideae (ingroup) and four taxa of Cedreloideae (outgroup), this study 1) provides a first assessment of the genetic diversity of Aglaia elaeagnoidea; 2) investigates the geographic structure of the data in selected eastern and western regions of its distribution; and 3) suggests...

A new Silver Dollar species of Metynnis Cope, 1878 (Characiformes: Serrasalmidae) from Northwestern Brazil and Southern Venezuela
Provedor de dados: 83
Autores: Ota,Rafaela Priscila; Py-Daniel,Lúcia Helena Rapp; Jégu,Michel.
ABSTRACT A new Metynnis is described from the rio Negro in Brazil and Venezuela, and from black- or clearwater tributaries in Brazil including the rios Parauari, Uatumã, Trombetas, and Sucunduri (the latter belonging to the rio Madeira basin). The new species can be distinguished readily from all congeners by having a high concentration of dark chromatophores on the lateral line scales. It can be further distinguished by the combination of head length 24.3-27.5% of SL, 13-18 gill-rakers on upper limb and 16-24 gill-rakers on lower limb. The new species is most similar to and likely most closely related to Metynnis hypsauchen . These two species share a similar color pattern, body shape and sexual dimorphism of the anal fin. However, they differ in that M....

A new species of Hyphessobrycon Durbin is described from tributaries of the rio Grande (rio São Francisco basin) draining east to the Serra Geral de Goiás, of the rio São Domingos (upper rio Tocantins basin) and rio do Sono basins (middle rio Tocantins basin). Hyphessobrycondiastatos can be diagnosed from its congeners by the absence of humeral spot, 15-18 branched anal-fin rays, 1-3 maxillary conical to tricuspid teeth, a relatively well-defined dark caudal-peduncle spot, and elongation of dorsal- and anal-fin rays in mature males. The biogeographical significance of the distribution of the new species is evaluated and discussed.

Phylogeography of the banded butterflyfish, Chaetodon striatus, indicates high connectivity between biogeographic provinces and ecosystems in the western Atlantic
Provedor de dados: 83
Autores: Liedke,Ana M.R.; Pinheiro,Hudson T.; Floeter,Sergio R.; Bernardi,Giacomo.
ABSTRACT Among the four butterflyfishes of the genus Chaetodon present in the western Atlantic, the banded butterflyfish Chaetodon striatus has the largest distribution range, spanning 44 degrees of latitude (from Massachusetts, USA to Santa Catarina, Brazil). Although the ecology of the banded butterflyfish has been well studied over its entire range, nothing is known about its phylogeography and how biogeographic barriers structure its populations. To assess the level of genetic connectivity among populations from distinct biogeographic provinces and environmental conditions, we collected samples from seven localities: Puerto Rico, in the Caribbean, and Tamandaré, Salvador, Abrolhos, Trindade Island, Arraial do Cabo and Florianópolis, in Brazil.

A review of the systematic biology of fossil and living bony-tongue fishes, Osteoglossomorpha (Actinopterygii: Teleostei)
Provedor de dados: 83
Autores: Hilton,Eric J.; Lavoué,Sébastien.
ABSTRACT The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of morphological, systematic, and evolutionary study, due in part to their basal position among extant teleostean fishes. This group includes the mooneyes (Hiodontidae), knifefishes (Notopteridae), the abu (Gymnarchidae), elephantfishes (Mormyridae), arawanas and pirarucu (Osteoglossidae), and the African butterfly fish (Pantodontidae). This morphologically heterogeneous group also has a long and diverse fossil record, including taxa from all continents and both freshwater and marine deposits. The phylogenetic relationships among most extant osteoglossomorph families are widely agreed upon. However, there is still much to discover about the systematic biology of these...

Coptobrycon bilineatus (Ellis, 1911) (Characiformes: Characidae): redescription and comments on its phylogenetic relationships
Provedor de dados: 83
Autores: Langeani,Francisco; Serra,Jane Piton.
Coptobrycon bilineatus (Ellis, 1911) is redescribed on the basis of specimens from the District of Paranapiacaba, Municipality of Santo André, upper rio Tietê, and additional ones recently collected in a small coastal river system of Serra do Mar, very near the headwaters of the rio Tietê. The genus was compared to other Characidae lacking a supraorbital, and it seems to be more phylogenetically related to Grundulus based on the possession of various putative apomorphic character states related to: the absence of a rhinosphenoid and fourth, fifth (sometimes) and sixth infraorbitals; nasal pores separated; nares with up to six nasal lamellae; cephalic laterosensory system poorly developed on supraorbital and infraorbital series; and a globose scapula....

Provedor de dados: 83
Autores: Ota,Rafaela P.; Lima,Flávio C. T.; Pavanelli,Carla S.
A new Hemigrammusis described from the rio Paraguai and rio Madeira basins, Mato Grosso and Rondônia States, Brazil. The new species is characterized by possessing a wide dark horizontal stripe across the eye, a vertically elongated humeral blotch, and 4-5 gill-rakers on upper branch and 9-10 on lower. The new species can be easily diagnosed from H. lunatus, the sympatric and morphologically most similar congener, by the shape of humeral blotch and the number of gill rakers. Data of the type material of both Hemigrammus lunatus and H. maxillaris, as well as extensive examination of specimens, allowed us to conclude that H. maxillarisis a junior subjective synonym of H. lunatus. A redescription of H. lunatus, as well as a formal restriction of its type...

Autores: Menezes,Naércio A.; Weitzman,Stanley H.
The systematics of the Glandulocaudinae is reviewed in detail and justification for the recognition of the group as a subfamily is discussed. The subfamily Glandulocaudinae consists of three genera: Lophiobrycon with one species plesiomorphic in some anatomical features but some others exclusively derived relative to the species in the other genera; Glandulocauda with two species intermediate in phylogenetic derivation; and Mimagoniates with seven species (one new), all more phylogenetically derived concerning their pheromone producing caudal-fin organs and with other anatomical characters presumably more derived than in the species of the other genera. Glandulocauda melanogenys Eigenmann, 1911, is considered a junior synonym of Hyphessobrycon...

Amazonspinther dalmata, a new miniature characid from the streams of rio Purus and rio Madeira, right bank tributaries of the rio Amazonas, is described as a new genus and species of the subfamily Cheirodontinae. The unique characters of the new genus and species are the three remarkable black blotches on the base of the dorsal, anal, and caudal fins, the anteriormost proximal radial of the anal fin with an anteriorly extended lamina entering the abdominal cavity, and the extremely elongate caudal peduncle. The reduced number of ventral procurrent caudal-fin rays (7-9), and the hemal spines of only posterior one, two, or sometimes three caudal vertebrae directly articulating with the ventral procurrent caudal-fin rays further diagnoses the new taxon from...

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.

A new species of Austrolebias Costa (Cyprinodontiformes: Rivulidae) from northeastern Uruguay, with comments on distribution patterns
Provedor de dados: 83
Autores: Loureiro,Marcelo; Duarte,Alejandro; Zarucki,Matías.
A new species of Austrolebias is described based on individuals from the middle and upper río Negro (río Uruguay basin) and río Yaguarón (Patos-Merín system). The new species can be differentiated from all other species of the genus by the unique presence in males of uniform bluish gray pigmentation on flanks (without vertical bands) and unpaired fins. The new species is also distinguished by the combination of characters associated with a reduction of the squamation of the abdominal, preopercular, and opercular regions. The new species presents some morphological characteristics similar to A. gymnoventris and A. luteoflammulatus. The distribution of the new species is concordant with three other species of Austrolebias and may represent a case of drainage...

Revision of the genus Pseudotocinclus (Siluriformes: Loricariidae: Hypoptopomatinae), with descriptions of two new species
Provedor de dados: 83
Autores: Takako,Adriana Kazue; Oliveira,Claudio; Oyakawa,Osvaldo Takeshi.
The genus Pseudotocinclus is revised and two new species are described: Pseudotocinclus juquiae from the Ribeira de Iguape basin and Pseudotocinclus parahybae from the rio Paraíba do Sul basin. The presence of a small naked area on the snout tip distinguishes P. tietensis from P. parahybae and P. juquiae, which have the snout tip covered with small platelets. In addition, P. tietensis has four transverse dark-brown bands on the dorsum coalesced with the midlateral stripe instead of three, as in its congeners. Pseudotocinclus juquiae is distinguished from its congeners by having the orbital ring very prominent and conspicuous, a characteristic not found in P. tietensis or P. parahybae. These three species also differ from their congeners by meristic and...

Description of males of Phallotorynus pankalos Lucinda, Rosa &amp;amp; Reis, 2005 and reappraisal of Phallotorynus species relationships (Teleostei: Cyprinodontiformes: Poeciliidae)
Provedor de dados: 83
Autores: Lucinda,Paulo H. F.; Graça,Weferson J. da.
Recently discovered male specimens of Phallotorynus pankalos are described and diagnosed from males of congener species on the basis of gonopodial morphology, color pattern and number of dorsal and anal-fin rays. The phylogenetic hypothesis of relationships among Phallotorynus species is reappraised with the inclusion of P. pankalos. Phallotorynus pankalos is hypothesized as sister to P. jucundus, a clade sister to P. victoriae or to a clade composed of P. dispilos and P. psittakos. Biogeography of Phallotorynus species is discussed, and it is suggested: (1) an early basal split between the rio Paraíba do Sul drainage and the Paraná-Paraguay system, separating P. fasciolatus from the ancestor of the remaining Phallotorynus species followed by a dispersal...

ABSTRACT Here we explore the use of community phylogenetics as a tool to document patterns of biodiversity in the Fitzcarrald region, a remote area in Southwestern Amazonia. For these analyses, we subdivide the region into basin-wide assemblages encompassing the headwaters of four Amazonian tributaries (Urubamba, Yuruá, Purús and Las Piedras basins), and habitat types: river channels, terra firme (non-floodplain) streams, and floodplain lakes. We present a robust, well-documented collection of fishes from the region including 272 species collected from 132 field sites over 63 field days and four years, comprising the most extensive collection of fishes from this region to date. We conduct a preliminary community phylogenetic analysis based on this...

Species of Decapod Crustaceans and their distribution in the american marine zoogeographic provinces.
Provedor de dados: 20
Autores: Boschi, E.E.
Fourteen marine zoogeographic provinces and two subprovinces were established for the Americas. The number of species of marine decapod crustaceans recorded in the supralittoral, intertidal, eulittoral and sublittoral (continental shelf to 200-300 m) including both, continental coasts from the Arctic Polar region in the north to Cabo de Hornos in the south is estimated at 2472 species. The results of this study on the biodiversity and distribution of decapod species call attention to a common characteristic of typical epifaunal groups of organisms with a large range of latitudinal geographic distribution: a high number of species in tropical regions on both coasts and a pronounced decrease of taxa towards the polar regions that generates a clear clinal...

The fauna of the Argentine (SW Atlantic Ocean) shelf allows to distinguish two biogeographic provinces: the Argentine and the Magellanic that are part of the Subtropical and Subantarctic Regions. The former extends from 30° S-32° S to 41° S-44° S and from the coast to the 82-95 m isobath, between 35° S-39° S, to 70 m depth in the north Patagonia. The latter extends from the Valdés Peninsula to the southern extreme and from 43° S northward, east area of the Argentine Province. The different physiographic characteristics allow to distinguish movable sandy bottoms in the Argentine Province and in the Magellanic gravel bottoms where large algae grow. The climatic differences explain the prevalence of northern winds in the first, where warm and temperate-cold...

San Blas Bay is part of a natural reserve located in the southern part of Buenos Aires province, which has a great value in terms of tourism, ecology and productivity. According to different sampling methodologies used in this thesis 11 species of chondrychthes, 26 species of bony fish, and a hagfish (Class Petromizontida) were recorded, with a predominance of species belonging to Buenos Aires biogeographic province. To evaluate the fish assemblage seasonal pattern, every three months...

The information gathered in Argentine anchovy (Engraulis anchoita) Northern population assessment cruises allowed to perform studies on the zooplankton community of the Buenos Aires shelf since 1995. In this work the most relevant results as regards the taxonomy and size structure of the community, faunistic areas, and 'key' species in relation to the hydrographic conditions and frontal systems of the region are presented. Besides, the consequences those results might have on Argentine anchovy trophic ecology are analyzed. The taxonomic groups studied included copepods, cladocerans, appendicularians, chaetognaths, amphipods, and euphausiids. The multivariate analysis applied to quantitative data allowed to clearly distinguish three faunistic areas with...

The marine biodiversity of the western Indian Ocean and its biogeography: How much do we know?
Provedor de dados: 20
Autores: Richmond, M.D.
Prior to the 1960s the biota of the western Indian Ocean inshore marine habitats received scant attention from taxonomists resulting in a poorly known flora and fauna. Fortunately, over the last 40 years there have been considerable developments in the study of marine biodiversity in this region, both from regional scientists and by those based at institutions in Europe and elsewhere. This paper reviews the current status of taxonomic knowledge of the marine biodiversity of the western Indian Ocean, focusing on the macroflora and macrofauna of the intertidal and shallow subtidal environments. The taxonomy of many of the smaller and particularly the softer-bodied invertebrate taxa remains a challenge to specialists, and as a result these taxa continue to be...

The St. Lucia System
Provedor de dados: 20
Autores: Cowan, G.I.
The St. Lucia System is found at the southern end of the Mozambique Floodplain and has a subtropical climate, warmed by the Agulhas current. Biogeographically, it lies at the interface between tropical and temperate biota, providing the northern distribution limits to a number of temperate species and the southern distribution limits to a number of tropical species. It has a high species diversity partly as a result of this position but also because of variability in both physical characteristics and soil conditions.

Population genetic status of the Western Indian Ocean:  what do we know?
Provedor de dados: 20
Autores: Sampayo, E.M.; Ridgway, T.
Population genetics offers a useful technique for studying the population structure of marine organisms and has relevance to both systematics and the conservation of biodiversity. The Western Indian Ocean (WIO) is faced with increasing evidence of degradation and effective management initiatives are needed to curtail the environmental decline. The management of the WIO region can therefore benefit from the information that population genetics can provide. Extensive literature searches revealed only 31 genetic references for the WIO region. From a biogeographic point of view, the WIO shows little genetic exchange with the rest of the Indo- Pacific, but from a regional perspective, the limited information that exists points towards widespread genetic...

Abstract The White-collared Kite (Leptodon forbesi) is an endemic and threatened raptor of the Brazilian Atlantic Forest. Here we present the known records of the species, describe the vegetation types where it was found and show Ecological Niche Models generated using Maxent algorithm. Most of the presence data were recorded in open ombrophilous forest and seasonal semideciduous forest in the states of Alagoas and Pernambuco. Maxent model had a good performance (AUC = 0.982 ± 0.004 SD), showing higher suitability for the species from Paraíba to Alagoas states. Maxent average model revealed a distribution range of 20,344 km² and an area of occupancy of 1,636.89 km². The most suitable areas for the species are those near watercourses and streams.

Phylogenetic relationships of a new species of Apostolepis from Brazilian Cerrado with notes on the assimilis group (Serpentes: Colubridae: Xenodontinae: Elapomorphini)
Provedor de dados: 84
Autores: Ferrarezzi,Hebert; Barbo,Fausto Erritto; Albuquerque,Cristina España.
The assimilis species group is one of the several assemblages that can be distinguished within the genus Apostolepis. The group is characterized by a uniform red dorsal pattern, broad nucho-cervical collars, enlarged light snout blotch, dark ventral head, and entirely black terminal shield. A new species is here recognized as a member of the assimilis group and its phylogenetic relationships to A. assimilis and A. cearensis is inferred by means of cladistic analysis. Apostolepis ammodites sp. nov. can be easily diagnosed from all congeners by many autapomorphies and an exclusive combination of features. Comparative data are presented on scalation, coloration, dentition, osteology, and geographic distribution, with some notes on feeding and reproductive...

Birds of Santa Teresa, Espírito Santo, Brazil: do humans add or subtract species?
Provedor de dados: 84
Autores: Willis,Edwin O.; Oniki,Yoshika.
In uplands and lowlands of Santa Teresa, central Espírito Santo State, Brazil, 405 bird species were confirmed by field, museum, and literature studies. Of these, 16 seem to have disappeared, while 67 other species seem to have been lost from the lowlands (where no large biological reserves exist). Due to a suggestion that human areas add species to beta-diversity, we verified that up to 79 species now present have perhaps "invaded" with human activity (and 10 others are likely to invade), a total similar to that for lost species. However, lost species are often rare and invading species often widespread, resulting in exchange of "Picassos for Coca-Cola bottles." Furthermore, gains exceed losses only when large biological reserves are present, as in the...

Why biogeographical hypotheses need a well supported phylogenetic framework: a conceptual evaluation
Provedor de dados: 84
Autores: Santos,Charles Morphy D.; Amorim,Dalton S.
A growing number of biogeographical methods have attempted to describe formal means of reconstructing the biogeographical history of the organisms. Whatever the biogeographical method, however, the source of systematic information has to be well worked out. Taxonomic noise is sometimes a true impediment to properly deal with the complexity of life in its three-dimensional aspects, the threefold parallelism represented by form, space and time. This paper argues that historical systematics is a necessary basis for a historical biogeography. Organismal phylogenies or at least hypotheses of monophyly should be taken as the basis for the study of distribution patterns. Whenever a non-monophyletic taxon is misleadingly taken as monophyletic, erroneous...

Historical Biogeography of a Clade of Liolaemus (Iguania: Liolaemidae) based on ancestral areas and dispersal-vicariance analysis (DIVA)
Provedor de dados: 84
Autores: Díaz Gómez,Juan Manuel; Lobo,Fernando.
Although many phylogenetic studies have been made on the genus Liolaemus, they are inappropriate for a biogeographic study because of incomplete taxon sampling. Here we develop a biogeographic analysis using a new phylogenetic study of the chiliensis group, which differs from the other studies in having his members fully represented. The biogeographic analysis presented here consists in reconstructing the ancestral area of this clade, under three different methods of analysis: Fitch Optimisation, Dispersal Vicariance Analysis and Weighted Ancestral Area Analysis. The analyses were made on phylogenies from parsimony under equally weighted characters, as well as under implied weighting. The equally weighted tree recovers most of the groupings proposed in...

Abstract We report the first record of the Choco broad-nosed bat (Plathyrrhinus chocoensis Alberico &amp; Velazco, 1991) in Santo Domingo de los Tsáchilas province in northwestern Ecuador. This voucher specimen represents the southernmost record of the species and expands its distribution ca. 120 km south. The animal was caught at a farm, specifically in a live fence consisting of several tree species. Preservation of bat species occurring in agricultural landscapes requires local policies and environmental education.

Distributional patterns of the neotropical fly genus Polietina Schnabl &amp;amp; Dziedzicki (Diptera, Muscidae): a phylogeny-supported analysis using panbiogeographic tools
Provedor de dados: 84
Autores: Nihei,Silvio Shigueo; Carvalho,Claudio José Barros de.
Over the last decades, Neotropical region has been subdivided into smaller units (areas of endemism), yet these subdivisions were not necessarily based on an evolutionary perspective. Consequently, these areas of endemism may be biogeographic units that do not actually represent natural historical units. Here, the distributional patterns of the genus Polietina Schnabl &amp;amp; Dziedzicki, 1911 (Diptera, Muscidae; including 15 species) are analysed by applying panbiogeographic tools to recognise and propose primary homologous areas within the Neotropical region. The analysis and discussion of the results obtained here will be reconciled to the information provided by the phylogenetic hypothesis available for the genus.

Soil oribatid mite in four typical vegetation communities of Misiones forest in the Iguazú area, Argentina
Provedor de dados: 86
Autores: Martínez,Pablo Antonio; Fredes,Natalia Andrea; Montti,Lia Fernanda; Casertano,Sergio Alejandro.
The objective of this work was to assess the soil oribatid mite communities in four sites of the Upper Paraná Bosque Atlántico, in the Iguazú National Park, Argentina and in surrounding areas: bamboo forest, palm forest and two mixed forests. A comparison between each pair of sites, based on the presence-absence of oribatid species, was performed using Jaccard's index. This is the first systematic sampling of oribatid mites in this area. A total of 56 genera and 96 oribatid species were found, 25 and 49 of them, respectively, are new citation for Argentina. The highest similarity was found between mixed forests. Almost 68% and 34% of the genera were cited for similar biotopes in Brazil and Paraguay, respectively.

Species composition and biogeographic relations of the rock outcrop flora on the high plateau of Itatiaia, SE-Brazil
Provedor de dados: 88
Autores: Ribeiro,Kátia Torres; Medina,Branca Maria Opazo; Scarano,Fabio Rubio.
We studied the flora of vegetation islands on rock outcrops on the Itatiaia Plateau (22°21'S and 44°40'W), at 2,400 m.a.s.l. A total of 114 vascular plant species, which correspond to ca. 20%-25% of the currently inventoried flora of the plateau, were sampled in 197 small vegetation islands (total area of 0.034 ha). Xerophytes and hydrophytes were often found side by side due to environmental heterogeneity at a small scale, explaining in part the high species diversity.

Biologia reprodutiva de Calibrachoa elegans (Miers) Stehmann &amp;amp; Semir (Solanaceae)
Provedor de dados: 88
Autores: STEHMANN,JOÃO RENATO; SEMIR,JOÃO.
Calibrachoa elegans é uma espécie anual, endêmica da região da canga do quadrilátero ferrífero de Minas Gerais, Brasil. O estudo da sua biologia reprodutiva envolveu experimentos de cruzamentos, teste do sistema de auto-incompatibilidade e observação do processo de polinização. Os experimentos realizados através de polinizações manuais indicam que a população estudada é preferencialmente alógama. A interrupção do crescimento do tubo polínico no estilete das flores autopolinizadas, verificada através da microscopia de fluorescência, confirmou a ocorrência de reação de auto-incompatibilidade. A polinização é realizada apenas pelas fêmeas de Hexantheda missionica (Colletinae, Apoideae), uma abelha com alta fidelidade de visita às flores de C. elegans. Os...

Provedor de dados: 88
Autores: Carvalho-Sobrinho,Jefferson Guedes de; Queiroz,Luciano Paganucci de.
(Morphological cladistic analysis of Pseudobombax Dugand (Malvaceae, Bombacoideae) and allied genera). Pseudobombax Dugand belongs to the family Malvaceae subfamily Bombacoideae and aggregates 29 species restricted to the Neotropics. A morphological cladistic analysis of Pseudobombax and allied genera was carried out to test the monophyly of the genus and to provide hypotheses on its phylogeny. Parsimony analyses were based on 40 morphological characters and 28 species, 14 belonging to Pseudobombax and 14 to other species of Bombacoideae, Matisieae (Malvoideae) and Ochromeae. Nine most parsimonious trees (144 steps, ci 0.40, ri 0.67) were produced when 10 multistate characters were taken as ordered while only two most parsimonious trees (139 steps, ci...

Autores: Gonçalves,Rodrigo Barbosa.
ABSTRACT Paroxystoglossa is a solitary, ground-nesting bee genus. It was revised in 1960 and currently includes nine species from Argentina, Brazil and Paraguay. The objectives of this contribution are to provide a morphological phylogeny for the group and to describe two new species: P. levigata n.sp. and P. mourella n.sp. Paroxystoglossa is monophyletic and three species groups are recognized, jocasta species group: (P. mourella n.sp., (P. brachycera, (P. jocasta, P. barbata))), transversa species group: (P. transversa, P. levigata n.sp.), and crossotos species group: (P. mimetica, (P. crossotos, P. seabrai, (P. andromache, P. spiloptera))). The crossotos and transversa species groups were considered as sister groups. Interestingly Paroxystoglossa...

Autores: Coelho,Marcel Serra; Almada,Emmanuel D.; Fernandes,G. Wilson; Carneiro,Marco Antonio A.; Santos,Rubens M. dos; Quintino,André V.; Sanchez-Azofeifa,Arturo.
Highly diverse forms of galling arthropods can be identified in much of southeastern Brazil's vegetation. Three fragments of a Seasonally Dry Tropical Forest (SDTF) located in the southern range of the Espinhaço Mountains were selected for study in the first survey of galling organisms in such tropical vegetation. Investigators found 92 distinct gall morphotypes on several organs of 51 host plant species of 19 families. Cecidomyiidae (Diptera) was the most prolific gall-inducing species, responsible for the largest proportion of galls (77%) observed. Leaves were the most frequently galled plant organ (63%), while the most common gall morphotype was of a spherical shape (30%). The two plant species, Baccharis dracunculifolia (Asteraceae) and Celtis...

Biogeographic analysis of Crocidiinae (Diptera, Bombyliidae): finding congruence among morphological, molecular, fossil and paleogeographical data
Provedor de dados: 92
Autores: Lamas,Carlos José Einicker; Nihei,Silvio Shigueo.
Biogeographic studies dealing with Bombyliidae are rare in the literature and no information is available on its origin and early diversification. In this study, we found evidence from molecular phylogeny and from fossil record supporting a Middle Jurassic origin of the Bombylioidea, taken as a starting point to discuss the biogeography and diversification of Crocidiinae. Based on a previously published phylogenetic hypothesis, we performed a Brooks Parsimony Analysis (BPA) to discuss the biogeographical history of Crocidiinae lineages. This subfamily is mostly distributed over arid areas of the early components of the Gondwanaland: Chile and southern Africa, but also in southwestern Palaearctic and southwestern Nearctic.

A new species of Serracutisoma (Opiliones: Gonyleptidae: Goniosomatinae) from the coastal Atlantic Rain Forest of Paraná and São Paulo states, Brazil
Provedor de dados: 103
Autores: DaSilva,Marcio B.
Serracutisoma gnaspinii sp. nov. is described from the coastal Ombrophylous Dense Atlantic Rain Forest of Paraná and São Paulo states. It differs from other Serracutisoma by having a retrolateral row of spines on femur IV, a rounded white-mark on the carapace and a low dorsal apophysis on trochanter IV. It is likely the sister-species of S. proximum, and with it and other five species forms the S. proximum group, herein formally proposed. Given that the biologic, phylogenetic and biogeographic aspects of Serracutisoma have been studied, the implications of the discovery of a new species are discussed, for instance the evolution of male fight, aggregation and maternal care, traits that are shared with other species. The geographic range of Serracutisoma...

Determinants of geographical distribution in Atlantic Forest species of Drymophila (Aves: Thamnophilidae)
Provedor de dados: 103
Autores: Rajão,Henrique; Cerqueira,Rui; Lorini,Maria Lucia.
Climate, altitude and vegetation are usually considered as limiting factors in plant and animal distribution. Among vertebrates, climate and vegetation have consistently been considered as major determinants of geographical distributions. Here we analyzed the role of climate and the vegetation in limiting the geographical range of Atlantic Forest species of Drymophila Swainson, 1824 and assessed the performance of discriminant analysis to model the distribution of sympatric taxa. From each empirical point (locality) we recorded the values for nine climatic variables and the type of vegetation. The climatic data were obtained from a climate database elaborated by the Laboratório de Vertebrados and vegetation data from the ecoregions digital map of Latin...

Geographic distribution and spatial differentiation in the color pattern of abdominal stripes of the Neotropical stingless bee Melipona quadrifasciata (Hymenoptera: Apidae)
Provedor de dados: 103
Autores: Batalha-Filho,Henrique; Melo,Gabriel A. R.; Waldschmidt,Ana M.; Campos,Lucio A. O.; Fernandes-Salomão,Tânia M.
Melipona quadrifasciata Lepeletier, 1836, regionally known as "mandaçaia", has been traditionally divided in two distinct subspecies: M. quadrifasciata anthidioides and M. quadrifasciata quadrifasciata. The main difference between the subspecies refers to the yellow metasomal stripes which are continuous in M. q. quadrifasciata and discontinuous in M. q. anthidioides. This study investigated the geographic differentiation in the metasomal stripes and characterized the restriction sites in the mtDNA of both chromatic types. Specimens from 198 localities were examined, and the variation observed in the pattern of stripes was grouped into distinct classes. The distribution pattern found in the present work agrees with the previously reported pattern: M. q....

The Neotropical lizard Mabuya agmosticha Rodrigues, 2000 is a habitat-specialist of thorny bromeliads in rocky outcrops of northeastern Brazil. Its distribution in the Caatinga Domain is most likely relictual. In recent years, new surveys conducted in northeastern Brazil have revealed new records of the species in the Caatinga and also in the Atlantic Forest Domain. In this study, we add four new records for M. agmosticha, extending its known geographic range in the states of Rio Grande do Norte and Paraíba. In addition, we investigated the potential geographical distribution of the species using ecological niche modeling (ENM), which combines the available occurrence records with environmental variables. Our model revealed a continuous range of areas with...

During the last decades, limnological studies on Chilean systems have contributed to know the species composition and main environmental variables of many water bodies distributed over a wide latitudinal interval, from 18º to 53º S. However, we still lack of a comprehensive view about the structure and functioning of regional freshwaters. In this work we review the available information about pelagic biota from Chilean basins, in order to reveal patterns of species distribution and their possible association with environmental variables. We built presence-absence matrices for phytoplankton, zooplankton and fish over lakes and basins. From this database, we performed parsimony analysis of endemicity as a tool for determining fundamental distribution...

The distribution of littoral caprellids (Crustacea: Amphipoda: Caprellidea) along the Pacific coast of continental Chile
Provedor de dados: 97
Autores: THIEL,MARTIN; GUERRA-GARCÍA,JOSÉ M.; LANCELLOTTI,DOMINGO A.; VÁSQUEZ,NELSON.
Many littoral caprellid species have a very ample distribution, some having been reported from all over the world. The cosmopolitan distribution of many littoral caprellid species might be facilitated by the fact that they are often associated with fouling communities on floating objects, which have a high potential of far-range dispersal. This dispersal potential may also have implications for the distribution of caprellids on local and regional scales. Herein we examined the distribution of littoral caprellid species on two spatial scales, local (tens of kilometers) and regional (hundreds of kilometers) along the Pacific coast of continental Chile. On the local scale, we studied the caprellid fauna in different habitats (intertidal boulders, subtidal...

Autores: NAVARRO,FERNANDO R; CUEZZO,FABIANA; GOLOBOFF,PABLO A; SZUMIK,CLAUDIA; LIZARRALDE DE GROSSO,MERCEDES; QUINTANA,M. GABRIELA.
The main purpose of this study is to analyze whether areas of endemism can be characterized quantitatively by using insects, which are typically much more poorly sampled than vertebrates or plants. For this, an optimality criterion in the search for endemic areas was used to analyze approximately 1,100 georeferences from 288 species of holometabolous insects found in the study region, the Yungas (a very moist, montane rainforest), located in north-western Argentina. The optimality criterion is implemented with the programs NDM/VNDM, used to evaluate areas of endemism (i.e. a set of cells defined by two or more endemic species). Five grid sizes were used, three square (Iº, 0.5°, and 0.25°) and two rectangular (0.25° x 0.5° and 0.5° x 0.25°). In agreement...

Autores: Donato,Mariano; Posadas,Paula.
Rodríguez et al. (2009) described a new species of the Podonominae genus Parochlus Enderlein. Several aspects of the abovementioned contribution concerning ecological and biogeographical aspects are discussed. The new temperature range proposed by the authors for this species is weakly supported by evidence and should be interpreted as tentative. The statement that this new record occurred in the Monte biogeographic province is erroneous. The type locality of the new species belongs to the Chacoan biogeographic province.

Autores: Michelette,Elen R.F; Camargo,João M.F.
The bee-plant community in a xeric ecosystem in northwestern Argentina was studied concerning diversity, relative abundance, floral preference and phenology. Fifty-seven bee species were recorded, 42.1% of them endemic to arid regions of southern South America, visiting flowers of 11 plant species. The most abundant bees were Canephorula apiformis (Friese, 1908), Isomalopsis niveata (Friese, 1908) and Melectoides bellus (Jorgensen, 1912). No strictly specialist bee was observed. Some aspects of bee-flowers associations and distribution patterns are discussed.

Recent advances in the biology of the Neotropical freshwater crab family Pseudothelphusidae (Crustacea, Decapoda, Brachyura)
Provedor de dados: 104
Autores: Rodríguez,Gilberto; Magalhães,Célio.
Pseudothelphusidae is a well diversified group of Neotropical freshwater crabs currently comprising 40 genera and at least 255 species and subspecies. The biology of these crabs has been an active field of research in the last 20 years. The aim of the present contribution is to discuss the significance of the new knowledge on the biology of these freshwater crabs after September 1992, to stress the interconnection of the diverse lines of research and at the same time to suggest promising new lines of investigation. All taxa described from September 1992 to October 2004 are listed, including one genus, one subgenus, 62 species and five subspecies. The implications of this new knowledge on the taxonomy, systematic and biogeography of the family are commented.

The systematic and biogeographical status of Fredius reflexifrons (Ortmann, 1897) and Fredius fittkaui (Bott, 1967) (Crustacea: Brachyura: Pseudothelphusidae) from the Amazon and Atlantic Guianas River basins
Provedor de dados: 36
Autores: MAGALHÃES,Célio; RODRÍGUEZ,Gilberto.
There is considerable confusion in the literature regarding the systematic position and distribution of two pseudothelphusid crabs originally described as Potamocarcinus reflexifrons Ortmann, 1897 and Potamocarcinus reflexifrons fittkaui Bott, 1967, and now included in the genus Fredius Pretzman, 1965, as F. reflexifrons and F. fittkaui. Study of numerous specimens from recent collections, together with a critical analysis of the data published in the literature, shows that both taxa could be easily separated by gonopodal characters. The two species occupy discrete areas of distribution along the main axis of the Amazon River and in the upper Rio Negro Basin, respectively, with an overlap in the Atlantic Guianas. It is postulated that they originated from...

Extension of the geographic distribution of Plecturocebus baptista (Pitheciidae, Primates) and a possible hybrid zone with Plecturocebus hoffmannsi: evolutionary and conservation implications
Provedor de dados: 36
Autores: ROCHA,Alessandro; BARNETT,Adrian P.A.; SPIRONELLO,Wilson R.
ABSTRACT Titi monkeys (family Pitheciidae) are Neotropical primates highly diversified in morphology, ecology and genetics, with a wide geographic distribution, including the Amazon, Atlantic Forest, Cerrado, Pantanal and Caatinga. This diversity, together with knowledge gaps, generates uncertainties in titi monkey taxonomy and distribution. An example is Plecturocebus baptista, with only 14 occurrence records and an ill-defined distribution based on untested geographical barriers. Here, we report the occurrence of this species at a new locality outside its known range, across the Paraná-Urariá River, which was considered a distributional limit for the species. The new record implies an overlap of P. baptista with the range of P. hoffmannsi. We document...

ABSTRACT We present an estimation of the potential species richness of frogs, and diurnal butterflies distributed in the departments of Norte de Santander and Santander, Colombia, and analyze the implications for conservation of such high Andean species. From June 2012 to May 2016, we sampled across the Almorzadero, Santurbán and Tamá biogeographical units to gather presence data of 7 anuran species and 29 butterflies species from the superfamily Papilionoidea. We modeled the potential distribution of each species, converted every model to binary, and the sum up of unique species per cell allowed to estimate the model of potential richness, generating the total number of species for every 1 km2 cell. Every model was validated against field data, vegetation...

Aspectos da evolução e da geografia do gênero Philodendron Schott (Araceae)
Provedor de dados: 39
Autores: Mayo,Simon J.
O gênero Philodendron se divide em três subgêneros, cada um com distintos padrões de morfologia, anatomia e distribuição. Em análise filogenética, o subgêneiro Meconostigma, o único com centro de especiação no sudeste do Brasil, mostra-se bastante apomórfico, ainda que cladisticamente primitivo no gênero. Análises fenéticas mostram que o gênero se constitue um taxon distinto, apesar de não ter um só caráter definitivo. Mostram também que feneticamente, Philodendron está mais perto de certos gêneros da África ocidental (Culcasia, Cercestis, Rhektophyllum) do que dos gêneros principalmente asiáticos com os quais está ligado pela classificação tradicional. A morfologia do gineceu varia muito no subgênero Meconostigma, com as formas mais simples ocorrendo no...

Provedor de dados: 39
Autores: Fernandes,Luciano Felício; Calixto-Feres,Mariana.
The epizoic diatoms Pseudohimantidium pacificum and Falcula hyalina, which live on copepods, were investigated using light and electron microscopes, based on material gathered from different marine environments along the Brazilian coast. Pseudohimantidium pacificum is reported for the first time for the Southwestern Atlantic Ocean, significantly enlarging its range of geographic distribution. This species usually covers the entire body surface of the copepods Corycaeus amazonicus and Euterpina acutifrons, and of cypris larvae of Cirripedia. Falcula hyalina uses a higher number of copepod hosts, particularly Oithona oswaldocruzii, Pseudodiaptomus richardii and Acartia spp. The valve morphology and biometrical data of both diatoms were within the range...

Autores: Soares,Caio J. R. S.; Sampaio,Mauricio B.; Santos-Filho,Francisco S.; Martins,Fernando R.; Santos,Flavio A. M. dos.
ABSTRACT Patterns of species diversity are essential to understand community structure. We aimed to determine species diversity and patterns of beta diversity in different spatial scales. We sampled three thousand individuals between the coordinates 22°10'S to 22°16'S and 47°47'W to 48°00'W to assess species diversity in three spatial scales (maximum distances of 80 m, 1,400 m, and 12,000 m), using the point-centered-quarter method. We partitioned gamma diversity into alpha and beta components. Beta diversity was partitioned into dissimilarities produced by spatial species turnover and nestedness. The contribution of beta diversity to gamma diversity was greater than that of alpha diversity in all scales, although the patterns of species diversity were...

Plate motions, Gondwana Dinosaurs, Noah's Arks, Beached Viking Funeral Ships, Ghost Ships, and Landspans
Provedor de dados: 42
Autores: Jacobs,Louis L.; Strganac,Christopher; Scotese,Christopher.
Gondwana landmasses have served as large-scale biogeographic Noah's Arks and Beached Viking Funeral Ships, as defined by McKenna. The latitudinal trajectories of selected Gondwana dinosaur localities were traced through time in order to evaluate their movement through climate zones relative to those in which they originally formed. The dispersal of fauna during the breakup of Gondwana may have been facilitated by the presence of offshelf islands forming landspans (sensu Iturralde-Vinent and MacPhee) in the Equatorial Atlantic Gateway and elsewhere.

On the occurrence and ecology of Glaucus atlanticus Forster, 1777 (Mollusca: Nudibranchia) along the Southwestern Atlantic coast
Provedor de dados: 42
Autores: PINOTTI,RAPHAEL M.; BOM,FABIO C.; MUXAGATA,ERIK.
Abstract: Unlike the majority of the nudibranchs, Glaucidae lives adrift at the sea surface within Tropical and Subtropical ocean basins, feeding on cnidarians or using them to attach their egg strings as a reproductive strategy. The latitudinal distribution of Glaucus atlanticus throughout the Brazilian Province is influenced by the Brazil current and, in its austral limit, by seasonal shifts in the Subtropical Convergence Zone (especially under the influence of ENSO El Niño events). Once over the shelf, seasonal wind patterns and meteorological events can force a passive displacement of the species towards the shore. Such onshore displacements may result on strandings of Glaucus spp. and other pleustonic species of the “blue plankton” community, like...

ABSTRACT The Brazilian Pantanal is an extensive wetland with heterogeneous habitats, primarily due to the river-floodplain system and plants with differential adaptations and reproductive strategies. Factors such as altitude, distance among plant formations, and flood pulse must be considered to better understand its diversity. Aiming to assess the influence of biogeographic patterns in this system, we analyzed the floristic composition of six areas along the Paraguay River, including residual relieves, verifying the pattern of similarity, and effects of distance and altitude. We recorded 356 species in 87 families, mostly perennial (75%), and some annuals (15%) and pluriannuals (5%). Herbaceous plants were the most represented (48%), followed by arboreal...

Golden mussel Limnoperna fortunei (Bivalvia: Mytilidae) distribution in the main hydrographical basins of Uruguay: update and predictions
Provedor de dados: 42
Autores: Brugnoli,Ernesto; Clemente,Juan; Boccardi,Lucía; Borthagaray,Ana; Scarabino,Fabrizio.
Limnoperna fortunei, an Asiatic rivers bivalve has become a worldwide problematic invasive species causing several water quality and macrofouling problems. In the Neotropical region it was first recorded in 1991 in the Río de la Plata coast, Buenos Aires province. Since this, it showed a quick upstream invasion into the principals aquatic systems of the Plata Basin. Nevertheless, there is not a study about its invasion and distribution process in aquatic systems of Uruguay. We describe the new records of Limnoperna fortunei in Uruguayan coast of Río de la Plata, Santa Lucía, Negro and Uruguay Rivers. With these results we aim to estimate its distributional limits for Uruguay main hydrographical basins. We also deal with the role of salinity as the main...

Diversity and evolution of Amazonian birds: implications for conservation and biogeography
Provedor de dados: 42
Autores: RIBAS,CAMILA C.; ALEIXO,ALEXANDRE.
Abstract: Amazonia has been a focus of interest since the early days of biogeography as an intrinsically complex and extremely diverse region. This region comprises an intricate mosaic that includes diverse types of forest formations, flooded environments and open vegetation. Increased knowledge about the distribution of species in Amazonia has led to the recognition of complex biogeographic patterns. The confrontation of these biogeographic patterns with information on the geological and climatic history of the region has generated several hypotheses dedicated to explain the origin of the biological diversity. Genomic information, coupled with knowledge of Earth’s history, especially the evolution of the Amazonian landscape, presents fascinating...

Autores: Resgalla Jr,Charrid.
This paper presents information from different sampling surveys carried out along the Santa Catarina coast in order to outline the biogeographical characteristics of the zooplankton in this region and identify species or groups of species with potential use as bioindicators. Based on a checklist of species of the zooplankton community in the state, it was observed that, in the warmer months of the year, the fauna is similar to that of the states of Paraná and São Paulo (e.g. Creseis virgula f. virgula, Penilia avirostris; Acartia lilljeborgi and Oithona oswaldocruzi), while in the colder months there are coastal representatives of the fauna of Rio Grande do Sul (e.g. Acartia tonsa). However, the zooplankton consists predominantly of warm water species for...

Abstract: The rio Ribeira de Iguape basin (Paraná State) is highly relevant for the preservation of remnants of the Atlantic Forest. Its high levels of diversity and fish endemism explain the river dynamics promoted by the Ponta Grossa Arch, a geological structure that promotes headwater capture and isolation between the upper rio Paraná drainage, the rio Iguaçu and the rio Ribeira de Iguape. Here, our objective was to provide an unprecedented inventory for headwater streams of the rio Ribeira de Iguape basin at the boundaries of the Ponta Grossa Arch. We found 29 species of fish representing four orders and nine families. Siluriformes was the richest order followed by Characiformes. Nine species presented high abundance of sampled individuals,...

The amazon bamboo rat Dactylomys dactylinus (Rodentia: Echimydae: Dactylomyinae) in the cerrado of central Brazil
Provedor de dados: 49
Autores: Bezerra,Alexandra Maria Ramos; Silva Jr.,Nelson Jorge da; Marinho-Filho,Jader.
Until recently, the distribution of Dactylomys dactylinus was considered to be restricted to forest habitats from the western Amazon to the east of the Xingu River in Brazil. Individuals of D. dactylinus were rescued in January 1997 from the rising waters of the hydroelectric dam of Serra da Mesa, in Central Brazil. This record extends the southern limit of the distribution of D. dactylinus, and represents also the first occurrence of this species in the Cerrado biome. The specimens were collected in patches of gallery forest of the Tocantins River and its tributaries. The Tocantins is the main river of the Araguaia-Tocantins basin. Its headwaters are located in the Cerrado biome and it is a tributary of the delta of the Amazonas River. The presence of D....

Trans-Amazon dispersal potential for Crotalus durissus during Pleistocene climate events
Provedor de dados: 49
Autores: Ingenloff,Kate; Peterson,A. Townsend.
Two disjunct distributional areas of Crotalus durissus(Neotropical rattlesnake) are in open habitats north and south of the Amazon Basin and are presently separated by humid rainforest habitats. We used ecological niche modeling to identify and investigate potential dispersal pathways for this species between the two areas during the late Pleistocene. Niches estimated for the two populations did not differ significantly. Our analyses indicated two possible, but a single most likely, potential routes of dispersal during the last glacial cycle. These results are important to understanding the history of Amazon Basin humid forest biotas, as they suggest agents of isolation among putative humid forest refugia in the form of dry forest and scrub, and associated...

For elaborating this list, the most relevant natural history collections where the material of the area’s is material is deposited were consulted, identifications were verified compared with type material and original descriptions and redescriptions. In the Colombian Caribbean Sea 48 cephalopod species are present in different environments, represented in 17 families and 33 genera. There is one Spirula, seven sepiolids, 21 squids, and 19 octopod species. Most animals are from shallow coastal waters.

Lorentziella (Gigaspermaceae, Bryophyta) new for Chile, and lectotypification of the genus
Provedor de dados: 51
Autores: Larraín,Juan; Fife,Allan; Atala,Cristian.
The genus Lorentziella is reported for the first time for Chile based on multiple collections done between the months of July and September 2016. New information is given about the ecology of this taxon and its global known distribution, as well as a distribution map. A lectotype for the genus Lorentziella is here selected and the genus authorship is corrected.

Biogeographic and species richness patterns of Gastropoda on the southwestern Atlantic
Provedor de dados: 57
Autores: FLOETER,S. R.; SOARES-GOMES,A.
Patterns of richness and biogeography of Gastropoda molluscs were determined based on lists of species from five sites along the southwestern Atlantic. The analysis of the distribution patterns of these sites confirmed the existence of a broader transition zone between southern Espírito Santo State (21°S) and Rio Grande do Sul State (32°S). This zone is very heterogeneous, presenting a low endemism rate and a significant number of species common to the near provinces, and does not show enough consistency to be considered as an independent biogeographic province as proposed by Palacio (1980). Observing the distribution of species along the southwestern Atlantic we find an increase in the proportion of species with greatest latitudinal ranges (occurring from...

A comparative study of coastal and clinical isolates of Pseudomonas aeruginosa
Provedor de dados: 58

Pseudomonas aeruginosa is a ubiquitous Gram-negative bacterium having a versatile metabolic potential and great ecological and clinical significance. The geographical distribution of P. aeruginosahas revealed the existence of an unbiased genetic arrangement in terrestrial isolates. In contrast, there are very few reports about P. aeruginosa strains from marine environments. The present work was aimed at studying the distribution of P. aeruginosa in coastal waters along the Indian Peninsula and understanding the environmental influence on genotypic, metabolic and phenotypic characteristics by comparing marine and clinical isolates. Of the 785 marine isolates obtained on selective media, only 32 (~4.1%) were identified as P. aeruginosa, based on their fatty...
