Genetic and morphometric differences between yellowtail snapper (Ocyurus chrysurus, Lutjanidae) populations of the tropical West Atlantic
Provedor de dados: 74
Autores: Vasconcellos,Anderson V.; Vianna,Paulo; Paiva,Paulo C.; Schama,Renata; Solé-Cava,Antonio.
Populations of Ocyurus chrysurus were compared genetically and morphometrically along the West Atlantic coast to test the null hypothesis of population homogeneity in the area. Brazilian populations were found to be differentiated in shape (canonical variates analysis; F[48,515] = 10.84, p &lt; 0.0001). Analyses of mitochondrial DNA sequences (663 bp of the control region) did not show any differences between Brazilian populations but could detect differences between Brazilian and Caribbean (Belize) populations. The samples from Pernambuco differed significantly from the other Brazilian populations in allozyme frequencies (11 loci; F ST = 0.167; p &lt; 0.05), but this may have resulted from the small number of samples analysed for that population. Sequence...

Provedor de dados: 74
Autores: Medrado,Aline Souza; Figueiredo,Alba Vivian Amaral; Waldschmidt,Ana Maria; Affonso,Paulo Roberto Antunes de Mello; Carneiro,Paulo Luiz Souza.
In the present work, morphometric and cytogenetic analyses were carried out in populations of the fish Astyanax fasciatus (Characidae) from Contas and Recôncavo Sul River basins (State of Bahia, Brazil), providing new data on the genetic structure of this species along the region. Based on morphologic measurements, we observed that populations from the same hydrographic basin were more similar to each other (Contas and Preto do Costa Rivers), and remarkably divergent from Recôncavo Sul (Mineiro Stream), as indicated by clustering analysis. Cytogenetic data revealed a same diploid number for all populations (2n = 48), but distinct karyotype formulae (8M+24SM+12ST+4A, FN = 92 in Contas River, 8M+24SM+10ST+6A, FN = 90 in Preto do Costa River, and...

Morphological characterization and sex-related differences of the mandible of the armadillos Chaetophractus vellerosus and Zaedyus pichiy (Xenarthra, Dasypodidae), with consideration of dietary aspects
Provedor de dados: 76
Autores: Sidorkewicj,Nora S.; Casanave,Emma B.
The morphological characteristics of the mandible of adult Chaetophractus vellerosus (Gray, 1865) and Zaedyus pichiy (Desmarest, 1804) were studied to establish its generalized design and to identify inter- and intra- (sexual) specific differences. Morphological descriptions were complemented with the application of univariate and multivariate (analysis of correlation matrices, PCA, discriminant analysis) techniques. The mandible of both species is very similar, and is characterized by elevated condyle, well developed angular process, distinct coronoid process, tooth row which extends to the rear end of the angle between body and ramus, and unfused but firm symphysis. Although both armadillos are omnivorous, a more slender configuration of the jaw in Z....

Provedor de dados: 76
Autores: García-Dávila,Carmen Rosa; Magalhães,Célio; Guerrero,José Camilo Hurtado.
Morphometric variability among shrimp populations of the genus Palaemonetes Heller, 1869 from seven lakes (Huanayo and Urcococha, in Peru; Amanã, Mamirauá, Camaleão, Cristalino e Iruçanga, in Brasil) in the Amazon Basin, presumably belonging to Palaemonetes carteri Gordon, 1935 and Palaemonetes ivonicus Holthuis, 1950, were studied. The morphometric studies were carried out from the ratios obtained from the morphometric characters. Multivariated analysis (Principal Components Analysis-PCA, Discriminant Function Analysis and Cluster Analysis) were applied over the ratios. Intra- and interpopulation variations of the rostrum teeth, and the number of spines in the male appendix, were analyzed through descriptive statistics and bivariate analysis (Spearman...

Provedor de dados: 76
Autores: Pardo,Erica Veronica; Teixeira,Laura Laund S.; Amaral,Antônia Cecília Z.
Accurate size measurements are fundamental in characterizing the population structure and secondary production of a species. The purpose of this study was to determine the best morphometric parameter to estimate the size of individuals of Capitella capitata (Fabricius, 1780). The morphometric analysis was applied to individuals collected in the intertidal zones of two beaches on the northern coast of the state of São Paulo, Brazil: São Francisco and Araçá. The following measurements were taken: the width and length (height) of the 4th, 5th and 7th setigers, and the length of the thoracic region (first nine setigers). The area and volume of these setigers were calculated and a linear regression analysis was applied to the data. The data were log-transformed...

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

The present work aim to develop a methodology, using digital images processing with morphometric data to subsidize the soil mapping, in order to guide the field work becoming survey faster, better precision and cheaper. Initially the Digital Elevation Model was made (DEM), for TOPOGRID method of the ArcInfo program, using 37 topographical letters in scale 1:10.000 the Jardim river basin. From the DEM the morphometric maps of the basin had been generated (slope, flow direction and contribution area), used to elaborate the color compositions and histograms analyses in order to allow the definition of soil pattern. After that was made the comparison with the soil map elaborated by Embrapa where could be conserved great similarity of the soil units.

Autores: Caill-milly, Nathalie; Mahias, Jérémy; Bru, Noelle; De Casamajor, Marie-noelle; Pigot, Thierry; Corbet, Paul.
This paper investigates whether morphological variability of test and Aristotle’s lantern can be detected in sea urchins exposed to domestic pollution and whether this variability can be also related to tidal level and hydrodynamic features. The study was conducted on four sites along the French Basque coast. Each site is characterized by its geological layers’ orientation, regardless of its proximity to sewage outlets. Analyses on high-resolution pictures of jaws were performed and three parameters were retained: length, height and demipyramid dry mass. Five shape descriptors were consequently defined regarding the test and the jaws. Individuals with heavy test density associated with highly developed demipyramid regarding test diameter and height were...

Autores: Caill-milly, Nathalie.
Significant component of the marine benthic ecosystem, exploited bivalves are mainly located inside the coastal area, which temporal and spatial features generate natural population fluctuations and contribute to considerable biomass and demographic structure changes added to anthropogenic activities’ effects (fishing, pollution,…). Understanding of the relationships between the species, its environment and its exploitation is crucial and their formalization, including for management purposes, requires development of mathematical models that aim at describing the functioning of the system, to explain the observed phenomenon in terms of cause and effect or predict effects of new causes. Originating from venerid culture trials carried out in France in the...

Provedor de dados: 5
Autores: Peruzzi, Stefano; Wiborg-dahle, Stine; Haffray, Pierrick; Chatain, Beatrice; Primicerio, Raul.
A method of geometric morphometrics was used to characterize body shape variation in meiotic gynogenetic and triploid sea bass in comparison with diploid controls. A total of 13 coordinate landmark data were recorded on the profile of 34-month-old control (n = 81), gynogenetic (n = 117) and triploid (n = 131) siblings generated from two females (A and B). Three main axes of morphometric variation were consistent, and these accounted for 60.8 and 57.6% of the total variability in females A and B, respectively. There were significant shape deviations of triploid and gynogenetic fish relative to the controls, and differences were particularly evident in the progeny of one female. Overall, triploids displayed a more slender shape than diploids, whereas...

Le complexe «Dinophysis acuminata»: identification des espèces le long des côtes françaises
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele.
From seawater samples collected between 1984 and 1989 in 12 French coastal areas, a morphometric study have been realised on Dinophysis genera restricted to "acuminata" like species. Simple morphological criterias are given as suitable for discrimination of four dominant species occurring during toxic episodes in shellfish farms (Diarrheic Shellfish Poisoning): Dinophysis c-closed-integral. sacculus, D. c-closed-integral. acuminata, Dinophysis sp. and D. c-closed-integral. norvegica. This last species cannot be included in the "acuminata complex" and produces temporary blooms along southern Brittany coasts. Pending a more precise diagnosis it is recommended to clarify the relationship between toxin composition and each species previously described.

Autores: Haffray, Pierrick; Bugeon, Jerome; Rivard, Quentin; Quittet, Benjamin; Puyo, Sophie; Allamelou, Jean Michel; Vandeputte, Marc; Dupont-nivet, Mathilde.
Selection to improve processing yields relies on sib selection, in which live candidates are ranked according to their family breeding value. This approach limits genetic progress, as it only exploits genetic variability between families and not within them. Indirect criteria measured on live candidates could overcome this limitation. The present study (1) proposes a procedure to identify indirect criteria to predict processing yields in rainbow trout (head, carcass and fillet yields), (2) estimates genetic parameters of these indirect criteria, and (3) predicts relative genetic gains in processing yields using full-sib selection or indirect individual selection on those indirect criteria.

Phenytoin (diphenylhydantoin, dilantin) has been the chosen anti-convulsive for the treatment of sudden disorders since the late 1930's. Several epidemiological and clinical studies in human beings showed an increase in malformations in descendants of which mothers took phenytoin during gestation, such as cranio-facial development and growth abnormalities, distal phalangeal hypoplasia, and light or moderate mental deficiency. This work had the goal to study the lingual mucosa, under histopathological and morphometric standpoints, in rat fetuses which were given an intraperitonial injection, consisting of a unique dose of phenytoin (70 milligrams/kilogram of their weight). Being that, we included the examined material in paraffin, 6 micrometers thick, and...

Diabetes is now considered one of the main threats to human health in the 21st century and many researchers are dedicated to investigate the physiopathology of the disease, with further insights on the managements of its major complications. Since understanding the pathophysiology of the major complications of diabetes and their underlying processes is mandatory, experimental models of the disease may be useful as they allow the recognition of the early mechanisms involved in the long-term complications of diabetes. Peripheral nerve involvement is highly frequent in diabetes mellitus and it has been documented that one third of diabetic patients have peripheral neuropathy. The true prevalence is not known and reports vary from 10% to 90% in diabetic...

Autores: Kavoi,Boniface M; Jameela,Hassanali.
Morphometric parameters of olfactory brain components show species-dependent variations. However, the association of these parameters with olfactory function vis-à-vis ecological and evolutionary behaviors is poorly understood. In this study, a morphometric analysis of the olfactory bulb, tract and stria was carried out in three ecologically diverse animals comprising humans (primate), dogs (carnivore) and goats (herbivore) to elucidate differences in morphometry in relation to olfactory function. Using formalin-fixed brains, volumes and linear measurements of the olfactory structures were determined and correlated with those of cerebrum and the whole brain. The volume of the olfactory bulb was greatest in dogs, followed by goats and humans and constituted...

The Mexican government passed a new reform of article 11 of the General Law in 2014 regarding Women's Access to a Life Free of Violence, which states that a cesarean section may not be performed if a vaginal birth is viable. Cesarean sections are excessively indicated in Northen Mexico, using the diagnosis of cephalopelvic disproportion due to a narrow pelvis. Currently, there is no standardized morphometry of the female pelvis in a Mexican population to establish adequate diagnostic parameter. Our study measures the pelvic diameters of the birth canal using abdominopelvic computed tomography (CT). Two hundred and ninety CT from Mexican women between the ages of 18 and 50 were collected and 3D reformatted in order to morphologically measure the pelvic...

The morphology of the acromion, its relation to the coracoid process and the supraglenoid tubercle is important in the determination of the dimension of the subacromial space, considering that the variations of these structures can promote pathologies such as impingement syndrome of the subacromial space. There is little information on the different dimensions and forms of the acromion. We studied in 36 scapulae at the museum of the Anatomy Unit, Universidad de La Frontera, the following parameters: length, denseness, width, anterior projection, distance acromiocoracoid and acromion supraglenoid. According to this form, the type was qualified in acromion type I (plane) type II (curved) and type III (hooked). The averages of the variable length, anterior...

Provedor de dados: 77
Autores: Rexhepi,Agron M; Brestovci,Behlul.
Morphometry is a non-invasive method important to assess the size, proportions, and composition of the human body. Because the prediction is an important subject in almost all life sciences, the aim of this research was to find out the cephalofacial variables that may predict the body height. Three cephalofacial variables and the body height were measured on 288 adult male subjects of the Kosovo Albanian population, aged 18­35 years old. Using the procedures of regressive analysis we found that cephalofacial variables: head height, head circumferences, face height, significantly may predict body height, and in this way we derived the specific regression equation for estimation of the body height, based on these cephalofacial variables. The predicted body...

The development of the paranasal sinuses, in human race and in many mammals remained as much an enigma as it did nearly two millennia ago. Morphometric analysis of maxillary sinuses in human foetuses are not fully documented and also their morphological studies in Indian population are non-existent. So the present study was conducted to determine the different diameters, the pattern of growth, sexual dimorphism and bilateral variations in maxillary sinuses. 37 human foetuses of different age groups (16 - 34 wks of IUL) were divided into five groups on the basis of age. Maxillary sinuses were dissected out from the nasal aspects of maxillae and their various diameters were measured with the help of Vernier callipers. The percent growth of AP diameter was...

Autores: Pillay,S; Ishwarkumar,S; De Gama,B.Z; Pillay,P.
The angle of mandible is formed by the tangent line joining the posterior margin of the ramus and the base of the mandible. The angle of mandible has population-specific characteristics therefore; it is imperative to the field of forensic anthropology for age and sex determination. Literary reports regarding the use of the angle of mandible for age and sex determination vary, as some studies support it, while other studies have documented inefficiencies. Therefore, the aim of this investigation was to document the morphometry of the angle of mandible and to determine if a correlation between the angle of mandible, age and sex exists. Sixty four digital panoramic radiographs (n=128) of individuals between 16-30 years were morphometrically analysed using the...

Autores: Abaidoo,C.S; Warren,M. A; Andrews,P. W; Boateng,K. A.
In order to study the detailed morphology of trophoblast cells during human implantation, BeWo cells were cultured as spheroids in suspension culture. These cultures were then processed for light and electron microscopical examination. The present study showed that the BeWo spheroids consist of two cell types which are cytotrophoblast-like and syncytiotrophoblast-like. The cells with larger nuclear diameter made up only about 1% of the cell population and appear to be those of syncytiotrophoblast. Therefore the predominant cell type of the BeWo spheroids appeared to be relatively undifferentiated and cytotrophoblast-like. About 10% of the BeWo cells in the present study were mitotic, indicating a highly proliferative population. Total cell number increased...

Provedor de dados: 77
Autores: Ishwarkumar,S; Pillay,P; DeGama,B. Z; Satyapal,K. S.
The mandibular condyle is the rounded protuberance that articulates with the mandibular fossa to form the temporomandibular joint (TMJ). The shape of the mandibular condyle may be classified according to five basic shapes viz. flattened, convex, angled, rounded and concave. Previous research indicated that variation in the shape and size of the mandibular condyle, exists and that population-specific differences may also occur. This study aimed to document the shapes and size of the mandibular condyle and determine their relationship with regard to sex, age and race (if any). The morphometric and morphological parameters of the mandibular condyle were measured and assessed in 54 dry mandible specimens (n= 108). The Wedel et al. (1978) classification scheme...

Out of 1608 Nigerian Sahel male goats (bucks) examined for cryptorchidism in an abattoir, 9 (0.6%) had right unilateral cryptorchidism. The coat colour-specific prevalence was highest among the brown bucks (2.1%); and was 0.8%, 0.6%, and 0.3% among black, white, back-and-white bucks, respectively. The condition was not found among bucks with brown-and-black, brown-and-white, and multiple coat colours. The right and left testes of normal bucks and the descended testes of cryptorchid bucks had comparable gross testicular measurements, but the retained cryptorchid testes were smaller in size. The estimates of the testicular measurements showed that testicular weights (with the entire epididymes), peripheral longitudinal lengths and mid-circumferences of the...

Their occurrence has increased considerably inclusively due to progressive population again. The present work aims at establishing a relation between this infirmity and its prognosis in patients submitted to the treatment recommended by Departament of Otolaryngology and Head Neck Surgery of the School of Medicine of São José do Rio Preto. To this effect, by means of karyometric optical microscopy, cell nuclei in the glottic region of 20 individuals, divided into groups according to their tumor stage and time of survival, were evaluated. Following comparation with a...

Autores: James Olukayode,Olopade; Hyelduku Danladi,Kwari; Isabella Onome,Agbashe; Silas Kalu,Onwuka.
A comparative study of ocular morphometry was done in goats in Nigeria using the three major breeds. The result showed that the circumferences (mediolateral and anteriorposterior) were fairly constant between the breeds. The mean relative eyeball weight ranged from (0.39 ­ 0.59) x 10-3. Asymmetry was observed between the right and left eyeball weights and circumferences in all breeds and there was disparity in the asymmetry. It was also observed that heavier eyeball weights did not always correspond to a wider circumference. Female WAD and RS goats had significantly heavier (p &lt; 0.05) eyeball weights than the males but that was not the case in the Sahel breed. Animals above one year had consistently higher values in most of the parameters examined on...

Provedor de dados: 77
Autores: Onar,Vedat; Belli,Oktay; Owen,Pamela R.
In the burial chamber M4 of the Van-Yoncatepe necropolis in eastern Anatolia, dated to the beginning of the first millennium before our time, fox skeletal remains have been discovered together with human skeletal remains. The fox remains consist of two skulls and a large number of skeletal (postcranial) bones. Examination of the material led us to the conclusion that five foxes had been buried in the chamber. Craniometric and osteometric measurements were carried out on the bones, and estimations of shoulder height and body weight have been calculated. Evaluation of all quantitative and qualitative data and comparison with modern fox species led to identification of the remains as red fox (Vulpes vulpes)

Autores: Bustos-Obregón,Eduardo; del Río,Fernando Costa; Sarabia,Luis.
Organophosphoric (OP) agropesticidas are amply used to increase food production. However, it has been verified that they induce alterations at testicular level related to the diminution of fertility in humans as in animals. On the other hand, different studies have been made to develop chemical or natural compounds that can induce an antagonistic effect to OP. In previous studies an extract from a plant, from the Peruvian Andes (Maca) has been recognized by its stimulating action on spermatogenesis. In the present study the effects of both external agents were evaluated on testicular sections of testis of adult male mice on a population of 52 mice CF1, divided at random in 4 groups (Control, Malathion, Maca, Malathion-Maca), with sacrifice intervals of...

Autores: Ilknur,Ari; Mustafa,Kafa Ilker; Sinan,Bakirci.
The pterion is a commonly used anthropologic and neurosurgical landmark defined as the junction of the sphenoid, temporal, parietal and frontal bones. It is commonly classified into four types based on sutural pattern: sphenoparietal, in which the sphenoid and parietal bones are in direct contact; frontotemporal, in which the frontal and temporal bones are in direct contact; stellate, in which all four bones come into contact at a point; and epipteric, in which a small sutural bone is found between the parietal bone and the greater wing of the sphenoid bone. In the present study, 44 Anatolian skulls from two different eras, Byzantine (13th century) and contemporary (20th century), were investigated for morphology and location of the pterion.

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

An Osteometric Evaluation of the Jugular Foramen
Provedor de dados: 77
Autores: Ishwarkumar,S; Naidoo,N; Lazarus,L; Pillay,P; Satyapal,K. S.
The jugular foramina (JF) are bilateral openings situated between the lateral part of the occipital bone and the petrous part of the temporal bones in the human skull. It is a bony canal transmitting neurovascular structures from the posterior cranial fossa through the base of the skull to the carotid space. Since the JF depicts variations in shape, size, height and volume between different racial and gender groups, along with distinctive differences in laterality from its intracranial to extracranial openings, knowledge of the JF may be necessary to understand intracranial pathologies. Therefore, the purpose of this study was to evaluate the morphometric measurements of the jugular foramen. Various morphometric parameters of the JF and its relation to...

Cytogenetics and redescription of Graomys (Rodentia, Sigmodontinae) from Chumbicha, Catamarca, Argentina
Provedor de dados: 81
Autores: Lanzone,Cecilia; Novillo,Agustina; Suárez,Natalia S.; Ojeda,Ricardo A.
The taxonomy, phylogenetic relationships and distribution of the genus Graomys are confusing. In this note we report karyotypic data for specimens of Graomys collected in Chumbicha, Catamarca Province, Argentina. Their karyotypes agree with G. centralis with 2n = 42. The individuals from Chumbicha are similar in morphology to G. griseoflavus but smaller. Our results suggest that Chumbicha's specimens are conspecific with G. medius. Moreover, we propose to synonymize G. medius with G. centralis. Other data of the genus suggest that the name G. chacoensis should be applied to specimens with 2n = 42.

Geometric morphometric analysis of skull morphology reveals loss of phylogenetic signal at the generic level in extant lagomorphs (Mammalia: Lagomorpha)
Provedor de dados: 16
Autores: Deyan Ge, D.; Yao, L.; Xia, L.; Zhang, Z.; Yang, Q.
The intergeneric phylogeny of Lagomorpha had been controversial for a long time before a robust phylogeny was reconstructed based on seven nuclear and mitochondrial DNA sequences. However, skull morphology of several endemic genera remained poorly understood. The morphology of supraorbital processes in Lagomorpha is normally used as a diagnostic characteristic in taxonomy, but whether shape change of this structure parallels its genetic divergence has not been investigated. In this study, we conducted a comparative analysis of the skull morphology of all 12 extant genera using geometric morphometrics. These results indicated that no significant phylogenetic signal is observed in the shape change of the dorsal and ventral views of the cranium as well as in...

Morphological and allozyme studies of midwife toads (genus Alytes), including the description of two new taxa from Spain
Provedor de dados: 16
Autores: Arntzen, J.W.; García-París, M.
Allozyme variation in 31 to 50 presumptive loci of 12 populations of European midwife toads of the genus Alytes show appreciable genetic divergences (DiNe from 0.29 to 0.72) among four groups. These groups correspond to A. cisternasii Boscá, 1879, A. obstetricans (Laurenti, 1768), A. muletensis (Sanchiz &amp; Adrover, 1979), and a new species from the Betic mountains described here as A. dickhilleni n. sp. Smaller divergences among geographic groups of populations of A. obstetricans (up to DNei = 0.17) support the existence of three geographic units in Europe corresponding to the previously recognized subspecies A. o. obstetricans and A. o. boscai Lataste, 1879, plus a third one described here under the designation of A. o. almogavarii n. ssp.

The choice of external morphological characters and developmental stages for tadpole-based anuran taxonomy: a case study in Rana (Sylvirana) nigrovittata (Blyth, 1855) (Amphibia, Anura, Ranidae)
Provedor de dados: 16
Autores: Grosjean, S.
The morphology of tadpoles has long received too little attention in taxonomic and phylogenetic contexts, beyond the use of Orton’s general tadpole types, despite the potential of larval characters for resolving problems in systematics. A possible explanation for this neglect is the ontogenetic variation of external morphology. In order to understand the value of larval characters in taxonomy and systematics, it is necessary to determine the developmental stage at which characters reach their definitive size, form and colour before meaningful comparisons can be made within and between species. Here I use the tadpole of Rana (Sylvirana) nigrovittata as a model organism to assess ontogenetic character variation. Morphometric measurements were taken, and...

A longitudinal study of two species of Belostoma Latreille (Heteroptera: Belostomatidae): allometry and ontogeny
Provedor de dados: 82
Autores: Iglesias,Mónica S.; Gaspe,María S.; Valverde,Alejandra C.
The multivariate allometric growth patterns from longitudinal data of leg and rostral segments of all instars of Belostoma elegans (Mayr) and B. cummingsi De Carlo are presented for the first time, and the allometric coefficients are compared. The segments of the middle and hind legs present allometric coefficients with opposite polarity to those of forelegs. This discrepancy in the ontogenetic trajectories may be due to the different functions of the legs. The foreleg main function is to capture of the prey, while the middle and hind legs are adapted to swimming. The relative size of rostral segments is an important taxonomic character in Belostoma. In B. cummingsi, the proximal segment is longer than the middle one, while in B. elegans they are subequal....

Centris aenea Lepeletier is a solitary bee that has raised interest in management to pollinate crops, such as acerola, Malpighia emarginata. This study investigated the level of morphometric variability among populations of C. aenea from Northeastern Brazil. Traditional and geometric morphometric analyses were used. Head length, leg length, wing length, and wing shape were measured in samples (5-10 females) from eight localities. We did not find statistically significant differences among the populations (P &gt; 0.01). The partial wing warps were similar in the populations and indicated that the bees were not morphometrically different. Our results suggest that C. aenea shows low population morphometric variability and highlight the need for further...

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

Several studies have focused on understanding the biochemistry and morphology of the fat body of the hematophagous mosquito Aedes aegypti (L.) (Diptera: Culicidae). In contrast, few studies, if any, have focused on morphological characters of the fat body in other mosquitoes, especially non-hematophagous taxa such as the culicid Toxorhynchites. Larvae of Toxorhynchites prey upon the larvae of other mosquito species and are used in vector mosquito control. We investigated aspects of the fat body trophocytes, including the morphometric analyses of the lipid droplets, protein granules and nuclei, during Toxorhynchites theobaldi (Dyar &amp;amp; Knab) post-embryonic development. Following the body weight increase from larval stage L2 to L4, the size of lipid...

Autores: Díaz-Murillo,Bertha P.; Ruiz-Campos,Gorgonio; Piller,Kyle R.; McMahan,Caleb D.; García-De-León,Francisco J.; Camarena-Rosales,Faustino.
ABSTRACT Population-level morphometric variation of the Mountain Mullet (Agonostomus monticola) was assessed in 419 adult specimens from 25 sample sites (river basins) across its Middle American distribution (Pacific and Atlantic-Caribbean drainages). This analysis was based on 36 standardized linear measurements and 19 landmarks on geometric morphometrics approach. Discriminant function analysis (DFA) revealed 19 linear morphological characters with significant variation among groups. Geometrically, the most notable changes were associated to the curvature of the frontal region of the head, the anterior and posterior insertion of the first dorsal and anal fins. The resulting grouping based on the DFA and geometric morphometrics techniques (Pacific-A,...

Autores: Spadella,Maria A.; Desan,Simone P.; Henriques,Teresa C. B. P. O.; Oliveira,Claudio.
ABSTRACT Callichthyidae comprises a well-corroborated monophyletic group divided into two subfamilies: Corydoradinae and Callichthyinae. A recent proposal, based on molecular data, suggests that Corydoradinae is composed by nine monophyletic lineages, possibly genera. The species pertaining to those lineages have extensive modification in the size of genome, including diploid, tetraploid and octoploid species. Considering the occurrence of these monophyletic lineages and that the variations in DNA content may imply in significant alterations on the structure of spermatozoa, this study analyzed the morphology of the male reproductive system and the morphometry of the head of the spermatozoa of representatives of the nine lineages of Corydoradinae, seeking...

Early morphological variation and induction of phenotypic plasticity in Patagonian pejerrey
Provedor de dados: 83
Autores: Crichigno,Sonia A.; Battini,Miguel A.; Cussac,Víctor E.
The aim of this work was to study two aspects of phenotypic plasticity in the Patagonian pejerrey Odontesthes hatcheri (Teleostei: Atherinopsidae) the dependence of the early morphology on developmental time and temperature, and the induction of morphological changes by controlled feeding in juveniles. Newly hatched free embryos, incubated at two different temperatures (13 and 18oC), and juveniles were used for the study and induction of phenotypic plasticity. Body and head shapes were analyzed with geometric morphometrics and linear measurements. Our results showed that shape variation at hatching was related to the bending of the embryo head on the yolk sac, increasing the head-trunk angle due to progressive straightening of the embryo. The head-trunk...

The recently described fish species, Astyanax altiparanae (tetra) is common in the upper rio Paraná basin, and has been reported in the Iguaçu basin. However, its natural origin in the rio Iguaçu is questionable. In the present work, karyotypical and morphological features of two populations of Astyanax altiparanae from the upper rio Tibagi and upper rio Iguaçu were compared. Both populations showed 2n=50 chromosomes and differences in their karyotype formula, NOR-bearing chromosomes and location of heterochromatin. Morphometric data from both populations were analyzed through free-size canonical variables. Cytogenetic and morphological results were mostly coincident showing exclusive markers that reflect their degree of populational isolation. In addition...

Autores: Junqueira,Nara Tadini; Leal,Cecília Gontijo; Alves,Carlos Bernardo Mascarenhas; Pompeu,Paulo Santos.
The rio das Velhas, located in central Minas Gerais State (Brazil), is a major tributary of the rio São Francisco. Despite several anthropogenic pressures, this basin supports more than 115 fish species. The aim of this study was to compare the morphological space occupied by fish assemblages in four regions (headwaters, upper, middle, and lower course) along the channel of the rio das Velhas. We try to answer the following question: Is there a change in the morphological organization of the fish along the longitudinal gradient of the river? Individuals from 67 species, collected at several sites in the basin from 1999 to 2008, were measured for 11 morphological attributes related to swimming behavior and habitat use. Through the graphs, the first two...

Trypanosoma evansi : A quantitative approach to the understanding of the morphometry-hematology relationship throughout experimental murine infections
Provedor de dados: 19
Autores: Tejero, F; Roschman-González, Antonio; Perrone Carmona, Trina Mercedes; Aso, P. M.
The morphometric characteristics of three Venezuelan isolates of Trypanosoma evansi, and the basic hematological features as well as host’s body weight were registered throughout experimental murine infections. The phenomena, trypomastigote morphometry dynamics, mouse hematological change and mice body variation, are related in statistical terms. In addition, the changeable morphometric characteristics of the hemoflagellate, and the host’s mutable hematological attributes, and the variable host’s body eight produced three different mathematical models generated by Multiple Linear Regressions that could explain the heterogeneous behavior of this eclectic parasite. Even more, supplementary mathematical models provided by Correspondence Analysis emphasize...

Autores: Pineda, S.E.; Hernandez, D.R.; Brunetti, N.E.; Jerez, B.
Morphological characters of two loliginid squids, Loligo gahi and Loligo sanpaulensis, in the SW Atlantic region off Argentina were studied to obtain a diagnostic criterion for their identification. Emphasis was placed on the taxonomic characters suitable to identify individuals in the whole size range. Considering the uncertainty associated to the correct identification of juveniles, their taxonomic status was confirmed using electrophoretic studies. Discrimination between species based on morphological characters proved to be more effective than meristic counts. A discriminant function that allows an easy separation of the two species is presented. The function, composed of two indices: fin width mantle length (FW/ML)and gladius width mantle length...

Autores: Díaz, M.V.
Nutritional condition studies allow the assessment of physiological state of each larva and thus, the establishment of favourable nursery areas which provide better survival and growth. In the present work, morphometrical, histological and biochemical techniques were employed to assess nutritional condition of anchovy, Engraulis anchoita, larvae captured in the Argentine Sea. Its results were complemented with oceanographic data and information about zooplankton abundances, both prey and predators of anchovy larvae. Anchovy larvae abundance and distribution would be mainly determined by physico-chemical variables. Even though no significant differences were found in larval nutritional condition among the studied areas, larval condition was slightly better...

The aim of this paper is to discuss the validity of the taxonomic status formerly assigned to the rough scad inhabiting shelf waters off Buenos Aires Province, Argentina. Until recently the species had been considered, mainly by Argentine authors, as Trachurus picturatus australis, on the basis of a description by Nani (1950). Other authors, however, consider that the only valid species for the West Atlantic is Trachurus lathami. In general terms, there references are based on rather scarce material for this region. In this paper, we compare meristic and morphometric data from 160 specimens collected off Mar del Plata. Statistical analysis of the characteristics lead us to conclude that the valid scientific name of the Argentine rough scad is Trachurus...

Provedor de dados: 84
Autores: FONSECA-PÉREZ,KIMBERLYN A.; MOLINA,CÉSAR; TÁRANO,ZAIDA.
ABSTRACT The coexistence of species with similar ecological requirements (food, space, time) has typically drawn attention of researchers because competition for resources is expected to be high. The diet and microhabitat occupation of two morphologically and ecologically similar species of Hylidae (Anura), Dendropsophus microcephalus and Scarthyla vigilans, were analyzed at a locality in north-western Venezuela, with the aim of addressing the potential for space and food competition between them. Diet was estimated through the analysis of stomach contents and microhabitat occupation was estimated through recordings of perch type, height and horizontal distance to water. Thirty-six prey categories (32 families, 4 orders) of arthropods were identified: 30...

Abstract: The objective of this work was to phenotypically characterize creole goats of the Moxotó, Azul, Canindé, Repartida, Marota, and Graúna breeds, comparing them with the Boer, Anglo Nubian, and Alpine exotic breeds, to identify the genetic groups of greater potential for carcass quality and resistance to infection caused by worm. Data on morphometric measurements were obtained for the count of worm eggs in grams of feces (WEGF), Famacha score, carcass measurements, and body weight from 308 animals, in a farm in the state of Piauí, Brazil. Repartida goats showed the highest average for wither height (61.55 cm) and rump height (62.16 cm), and Moxotó goats had the greatest ear length (13.45 cm). The Moxotó breed showed the highest means for carcass and...

Quantitative measures of leaf epidermal cells as a taxonomic and phylogenetic tool for the identification of Stanhopea species (Orchidaceae)
Provedor de dados: 85
Autores: Foroughbakhch,R; Ferry Sr,RJ; Hernández-Piñero,JL; Alvarado-Vázquez,MA; Rocha-Estrada,A.
Orchids of the genus Stanhopea are currently identified only by their floral structure characteristics. A statistical analysis of a significant number of species of this genus disclosed that measurements of adaxial and abaxial epidermal cell surface areas can be correlated with specific recognized species by a leaf printing method. This allows an objectively either positive or nearly positive confirmation of the identity of a species in the absence of flowers and without damage to plants. When ordering the mean values obtained for these surface areas in each species in a decreasing order, a correlation was observed in a hierarchical way that went from primitive to more advanced floral forms. This reflects the evolutionary radiation of the genus. It is...

More than one inseminated female in colonies of the independent-founding wasp Mischocyttarus cassununga von Ihering (Hymenoptera, Vespidae)
Provedor de dados: 92
Autores: Murakami,André S. N.; Shima,Sulene N.; Desuó,Ivan C.
In the primitively eusocial wasps, especially Polistini and Mischocyttarini tribes, the physiological condition of each individual is strongly associated with its dominance status in the colonial hierarchy. As a rule, in independent-founding wasps, female wasps are all morphologically alike, and their role is apparently quite flexible even as adults. However, some studies have shown that differences in body size can exist between reproductive and non-reproductive females. Thus, the present study aimed at detecting differences between reproductive (inseminated) and non-reproductive (uninseminated) individuals based on morphological and physiological parameters. We tape-recorded the daily behavioural repertory of six colonies of Mischocyttarus cassununga for...

Termite societies are structured by individuals that can be grouped into castes and instars. The development of these instars in most species occurs in irregular patterns and sometimes is distinguished subcastes in physical systems that originate polymorphic soldiers and workers. In this study, we characterized the morphological diversity of castes of apterous in Nasutitermes corniger. We collected four colonies of N. corniger, one every three months between May 2011 and February 2012. Individuals of the nest were separated into groups: larval stages, workers and presoldiers and soldiers. A morphometric analysis was performed on individuals from each group based on head width, metatibia, antenna, and thorax length. The data were submitted to discriminant...

The objective was to relate the coloration of fruits of Jatropha curcas L during the maturation process with morphometric (fruits and seeds) and germinative characteristics (seeds). Fruits were collected at various maturation stages from mast trees located in Eldorado/MS, and six maturation stages were visually classified based on fruit's epicarp color. Epicarp digital colorimetry was used to characterize maturation stages in addition to morphometric variables of length and width of fruits and seeds, as well their water content. For determining the physiological potential it was used germination test, emergence velocity index and first count of germination. Results indicated that seeds of J. curcas should be harvested when fruit epicarp shows a reading...

The large fruit-eating phyllostomid bat, Artibeus lituratus (Olfers, 1818), forearm 69-75 mm, body mass 66-82 g, has a diversified geographic distribution in the Neotropical region. Therefore it is subjected to different climatic conditions that affect its reproduction, leading to different reproductive strategies such as continuous reproduction, seasonal monoestry or seasonal bimodal polyestry. In this study we used morphometric and histological methods to analyze the annual reproductive activity of A. lituratus males in a population living in the Atlantic Forest, Southeastern Brazil. Testis mass, epididymis mass, gonadosomatic index, seminiferous tubule diameter, and Leydig cell nucleus diameter showed no significant differences (p &gt; 0.05) in the two...

Provedor de dados: 103
Autores: Poiani,Silvana B.; Cruz-Landim,Carminda da.
The bee species of the Apinae, in addition to the thoracic salivary glands, possess a pair of cephalic glands originating as branches of the excretory duct that crosses the head. These glands are known as cephalic salivary or labial cephalic glands. The degree of development of these glands in newly emerged, nurse and forager workers and virgin and egg-laying queens of Apis mellifera Linnaeus, 1758 and Scaptotrigona postica Latreille, 1807 were evaluated by measuring the secretory alveolar units. The area of the secretory alveoli, measured in total gland preparations, was used to evaluate differences in size. In both species, gland size was found to increase progressively from newly emerged workers to foragers and from virgin to egg-laying queens. A...

A common problem when trying to identify the sex of hatchling turtles is that juveniles are not obviously externally dimorphic and current techniques to identify sex are often invasive. In this paper, 300 eggs of Podocnemis expansa from Bananal Island, state of Tocantins (Brazil), were incubated at constant temperatures. The carapaces of the hatchlings were photographed and subjected to geometric morphometric analysis. The hatchlings were subsequently euthanized and had their gonads removed for sex determination. The pivotal temperature of P. expansa was 33.5ºC, confirming that this species has the highest pivotal temperature among reptiles. Geometric morphometric analysis of the shape of the carapace proved efficient in differentiating the sex of the...

Morphology of the shell of Happiella cf. insularis (Gastropoda: Heterobranchia: Systrophiidae) from three forest areas on Ilha Grande, Southeast Brazil
Provedor de dados: 103
Autores: Barbosa,Amilcar Brum; Santos,Sonia Barbosa dos.
We conducted a study on shell morphology variation among three populations of Happiella cf. insularis (Boëttger, 1889) inhabiting different areas (Jararaca, Caxadaço, and Parnaioca trails) at Vila Dois Rios, Ilha Grande, Angra dos Reis, state of Rio de Janeiro, Brazil. Linear and angular measurements, shell indices representing shell shape, and whorl counts were obtained from images drawn using a stereomicroscope coupled with a camera lucida. The statistical analysis based on ANOVA (followed by Bonferroni's test), Pearson's correlation matrix, and discriminant analysis enabled discrimination among the populations studied. The variable that most contributed to discriminate among groups was shell height. Mean shell height was greatest for specimens collected...

Gender-related diet composition and morphometry of the Restinga Antwren, Formicivora littoralis (Aves: Thamnophilidae)
Provedor de dados: 103
Autores: Chaves,Flávia G.; Alves,Maria Alice S.
Formicivora littoralis (Gonzaga and Pacheco, 1990), the Restinga Antwren, considered the only endemic bird species of the Restinga ecosystem (sandy plain coastal vegetation), is threatened with extinction. The scientific literature provides little information on the biology of this bird, which was discovered in 1990. We evaluate gender-related differences in the composition of the diet and morphometric measurements of this species. We tested the hypothesis that the sexes differ in what they eat and in morphometric characters. Our results revealed that the diet of the Restinga Antwren includes mainly arthropods, which is consistent with the diets of other Thamnophilidae. The lack of differences in the composition of the diet between the sexes does not...

Determination of larval instars in Chironomus sancticaroli (Diptera: Chironomidae) using novel head capsule structures
Provedor de dados: 103
Autores: Richardi,Vinicius S.; Rebechi,Débora; Aranha,José M. R.; Navarro-Silva,Mário A.
Determining the age composition of a population is important when conducting ecological, taxonomic and environmental assessments. Morphometric measurements of the head capsule, especially the length and width, are widely used in the identification of insect instars, but alternative ways for determining the age of insects can expand the options for the analysis of field and laboratory populations. This study evaluated the morphometry of the antennae, mandibles, mentum and ventromental plates to discriminate among the four larval instars of Chironomus sancticaroli Strixino &amp;amp; Strixino, 1981. The larvae were reared in the laboratory under constant temperature (25°C) and photoperiod of 12/12 hours for 19 days, with a supply of food. Fifteen larvae were...

Dimorphism and allometry of Systaltocerus platyrhinus and Hypselotropis prasinata (Coleoptera: Anthribidae)
Provedor de dados: 103
Autores: Mattos,Ingrid; Mermudes,José Ricardo M.; Moura,Mauricio O.
Males of sexually dimorphic anthribid species display structural modifications that suggest sexual selection. Polyphenism, which is expressed through morphological and behavioral novelties, is an important component of the evolutionary process of these beetles. In this study, we endeavored to ascertain the presence of variations in selected monomorphic traits, polyphenism in males, and variation in structures associated with sexual dimorphism and allometric patterns in two species: Systaltocerus platyrhynus Labram &amp;amp; Imhoff, 1840 and Hypselotropis prasinata (Fahraeus, 1839). To that end, we used Principal Components Analysis (PCA) and Canonical Variate analysis (CVA) to statistically analyze 26 measurements of 91 specimens. The PCA discriminated...

ABSTRACT The adductor pectoral fin muscle in post-spawning females of the white croaker Micropogonias furnieri (Desmarest, 1823) is described from a morphological, histochemical and morphometric perspectives. A description of the morphological characteristics was conducted after dissections in different layers, down to the deep layer. Five muscles were found: superficial, medial, radial and deep adductors, and dorsal arrector. Their fibers were studied after applying histochemical techniques: succinic dehydrogenase (SDH) to reveal mitochondria, periodic acid-Schiff (PAS) for glycogen, Sudan black for lipids, myosin adenosinetriphosphatase (mATPase) to reveal the types of fibers, and modified mATPase to evidence the capillaries. Fiber diameters were...

ABSTRACT This study aimed to verify whether the criterion of exhibition contests adopted for Campolina and Mangalarga Marchador breeds has been successful in recent years, i.e., if the subsequent generations have the morphology recommended by the standard of the breed allied with high-quality marcha, a four-beat ambling gait. The classifications achieved by each horse during national horse shows in morphology and gait contests underwent Spearman's correlation to verify the number of contests with a correlation between the classifications in the two judgments and those with no correlation. Next, the number of contests with or without such correlation underwent a frequency distribution test considering the variables breed, year, age, marcha category, and...

ABSTRACT This study aimed to determine the participation frequency and competitive performance of Campolina and Mangalarga Marchador horses in national shows concerning marcha type, sex, and age. To that end, the trial results of national horse shows between 2007 and 2017, comprising 1,781 Campolina and 5,239 Mangalarga Marchador animals, were extracted from the databases of the breeders’ associations of each breed. The results regarding participation frequency in these events and the performance achieved by horses were grouped by breed, marcha type, sex, and age group and then subjected to frequency distribution tests. In both breeds, most animals attended only one national show. However, when the specimens were separated by marcha type, sex, and age, it...

ABSTRACT This study used path analysis to establish the direct, indirect, and total effects of body linear and angular measurements on subjective morphological scores of the 247 Criollo horses that participated in their most important performance event, Freio de Ouro, in 2012. Freio de Ouro is the only event of the Criollo breed that considers morphology. Measurements of wither height, thoracic girth, cannon bone girth, body length, metatarsus length, croup length, shoulder width, head length, neck length, and upper neck girth, and the angles of rump, shoulder, and hock were taken. These morphometric measurements collectively explained 83% of the variation in morphological score. The measurements with the greatest total effects on score were neck length...

Autores: Ibiapina Neto,Vicente; Barbosa,Firmino José Vieira; Campelo,José Elivalto Guimarães; Sarmento,José Lindenberg Rocha; Santos,Natanael Pereira da Silva; Carvalho,Marcos David Figueiredo de.
ABSTRACT The present study was carried out to evaluate the phenotypic diversity between fighting cocks; roosters of the naturalized ecotypes Graúna Dourada, Brejeira, Teresina, and Nordestina; roosters of the Sertaneja genetic (synthetic) group; and family-farmed roosters via descriptive and multivariate analyses. The qualitative traits evaluated by descriptive analysis indicated a prevalence of single comb in the Graúna Dourada, Teresina, Nordestina, and Sertaneja ecotypes, whereas the Brejeira ecotype, fighting cocks, and family-farmed roosters have a pea-type comb, which can be viewed as a sign of introgression of the fighting cock in flocks of the region. Dark plumage prevailed across the groups. The quantitative traits subjected to multivariate...

Provedor de dados: 97
Autores: Méndez,Marco A.; Soto,Eduardo R.; Correa,Claudio; Veloso,Alberto; Vergara,Eliseo; Sallaberry,Michel; Iturra,Patricia.
Bufo spinulosus has a wide and fragmented range distribution in Chile (18&amp;deg; to 33&amp;deg; S) along altitudinal and latitudinal gradients. Genetic variation was estimated using RAPD (Random Amplified Polymorphic DNA) markers in 10 populations from northern and central Chile. Morphometric and genetic information was analyzed as a function of geographical origin. The correlation between genetic and morphometric differentiation was analyzed by the Mantel test. An increase in body size as a function of latitude was observed. Specimens from El Tatio had the smallest body size and the greatest morphometric divergence. The AMOVA applied to genetic data indicated that 57.85 % of the variance is explained by interregional differences and that 30.12 % of the...

The species Phaleria testacea Say, 1824 (Coleoptera, Tenebrionidae) varies a lot in size, and its populations along the coast of Brazil, where it lives buried in sandy beaches, have temporal and geographical variation in density. In order to find out which factors were contributing to these variations, we sampled populations from three different areas in Rio de Janeiro, during summer and winter. Simultaneously, we made an analysis of the different substracts where the individuals were found, including their total fresh weight. The results show a significant difference in size of individuals between and within populations, when summer and winter were compared. There is also a positive association between the population density of P. testacea and the amount...

Autores: Machado,Vilmar; Araújo,Aldo M. de; Mosmann,Cleri S.
This study presents data on morphometric variation for length and width of elytra in tive sympatric species of the genus Chauliognathus Hentz, 1830: C. flavipes Fabricius, 1781, C. octomaculatus Pie, 1915, C. expansus Waterhouse, 1878, C. fallax Germar, 1824 and C. lineatus Zwetsch &amp;amp; Machado, 2000. The meaning of this variation is discussed in the light of the theory of mimicry and visual communication between prey and predator. Females are larger than males in all species, except C. expansus. The analysis of variance for length of elytron as well as for width showed that the differences between species are significant for males and females; significant interaction (sex x species) was also found. The similarity in color pattern of these species, as...

Autores: Costa-Paiva,Elisa M.; Paiva,Paulo C.
Morphology has been the subject of several studies in Eunice specially in the context of the taxonomy and evolutionary relationships of taxa within this genus. In this study we opt for a morphometric approach comparing five species of Eunice to assess if it was possible to delimitate them by shape variables. The morphology of E.fucata, E.insularis, E. cf. ornata, E.rubra, and Eunice sp. was compared using traditional morphometric analysis of 16 measured variables. After removing the size-effect, a Canonical Variates Analysis applied to morphometric variables was able to discriminate all species. In CV1 two major groups of species were discriminated: E.fucata/E.insularis and E. cf. ornata/E.rubra/Eunice sp. CV2 strongly discriminated all species, with E....

The growth relations of the shrimps Farfantepenaeus brasiliensis (Latreille, 1817) and F. paulensis (Pérez-Farfante, 1967) were evaluated at Imboassica lagoon, Macaé, Rio de Janeiro State, between June 1995 and September 1997, in four periods after events of sandbar opening. This sandbar separated the lagoon from the Atlantic Ocean. Through the evaluation of the weight/length relationships for the two species, significant differences in each interval after the sandbar openings were observed, as much among males and females as among all individuals of the same species. The results indicated that both species presented negative allometric growth in most of the studied occasions. The frequency and abundance of the two species in the lagoon is linked to many...

The study was carried out with the objective of verifying which measures and morphometric ratios are more directly related to the body yield of Nile tilapia, Oreochromis niloticus, in two weight classes. Data were analyzed from 257 specimens of tilapia divided into two weight classes: p1 = 400 to 599  g and p2 = 600 to 900 g. The morphometric measurements standard length (SL), head length (HL), body height (BH) and body width (BW), and the ratios of these measures (HL / SL, BH / SL, BW / SL, HL / BH, BW / BH, BW / HL) were evaluated. The following body yields were calculated: carcass (RCAR), fillet (RFILE) and head (RCAB). The data were initially submitted to the "stepwise" procedure to eliminate problems of multicollinearity among the morphometric...

The aim of this study was to analyze the morphology and morphometry of lapillus otoliths of the catfishes Cathorops spixii and Genidens genidens from the coast of Paraná State, Brazil. We used 147 lapillus from C. spixii and 96 from G. genidens, of different size classes. Otoliths were characterized with smooth margins for both species but with different shapes: oblong for C. spixii and oval for G. genidens. The morphological differentiation between the two species is in the anterior region: rounded for C. spixii and pointed for G. genidens. The t-test results for otolith measurements were: length (t value = -2.88; p = 0.0042), height (t value = -6.87; p &amp;lt; 0.000001), anterior angle (t value= 9.84; p = 0.000001) and posterior angle (t value =0.41; p...

Current study investigates the effects of maternal protein restriction during pregnancy and lactation on the testis of immature rats. Female Wistar rats were mated and, after confirming pregnancy, they were divided into two groups: undernourished group (UG) fed on a diet with casein 8%, and control group (CG) fed on a diet with casein 17 %, during pregnancy and lactation. After weaning, male offspring from the two experimental groups were fed on normal diet up to 35 days old when they were euthanized. Body and testicular weights decreased in UG when compared to those in CG. Volumetric density of seminiferous tubules was higher in CG whilst intertubular space increased in UG. The number of lumenated seminiferous tubules was higher in CG than in UG. Tubular...

Abstract Chronic stress exposure commonly increases adrenals weight and changes their morphology. This study aimed to compare four methods to delimitate the cortical and medullary layers of adrenals glands in Nelore bulls. Fresh adrenals did not present differentiation between layers. Then, frozen adrenals were distributed in plastics bags with fixative Bouin (G1), 96ºGL ethylic alcohol (G2), 10% formaldehyde (G3), or 2.5% glutaraldehyde (G4). After 12 hours of fixation, the G1 adrenal glands did not show the entire cortical layer marked by Bouin’s solution. For G2 and G3 there was a poor contrast, while for G4 there was a reasonable contrast. After 24 hours of fixation, G1 had an excellent contrast between layers, while G2 and G4 had a reasonable contrast...

Abstract:Farfantepenaeus brasiliensis and F. paulensis are the most exploited shrimps of SE-S Brazilian coast. Our aim was to verify if adjacent nursery areas with different environmental condition (Sepetiba and Guanabara bays, SE Brazil) influence on shrimp populations (eg, CPUE) and body shapes. Samplings were carried out during 12 months in those bays ca. 85 Km far from each other. Carapace length (CL), total body length (TL), wet weight, abdomen size and TL/CL ratio were used to analyze variations in shape through regressions. In general, F. brasiliensis was 4 to 6 times more abundant than F. paulensis. The sex ratio differed from 1:1 in F. brasiliensis in both bays, with dominance of females, largest catches occur in autumn. However, differences in...

Autores: Xavier-Vidal,Ricardo.
The purpose of this work is to calibrate a not expensive microscope to be applied in Optical Disector estimation. The evaluation of "Z-axis" bias and the "Z-axis" calibration were made utilizing a cover slip and a "manual digimatic outside micrometer scale" (Mitutoyo, Japan). Calibrating the cover slip we performed the calibration of the "Z-axis" of a microscope. In the cover slip two lines were painted with different colors using a pen glass. A blue line was painted on the up surface and another line (red) on the bottom surface of the cover slip forming a cross. Two metal rings with one palette welded in each were adapted in the microscope. Other palette was welded in the gross focuses in order to restrict the route of the fine focuses (Z-axis study)...

Stereological tools in biomedical research
Provedor de dados: 42
Autores: Mandarim-de-Lacerda,Carlos A.
Stereological studies are more and more frequent in literature, particularly in the development/evolution, pathology, and neurosciences areas. The stereology challenge is to understand the structural inner threedimensional arrangement based on the analysis of the structure slices only showing two-dimensional information. Cavalieri and Scherle's methods to estimate volume, and Buffon's needle problem, are commented in the stereological context. A group of actions is needed to appropriately quantify morphological structures (unbiased and reproducibly), e.g. sampling, isotropic and uniform randomly sections (Delesse's principle), and updated stereological tools (disector, fractionator, nucleator, etc). Through the correct stereology use, a quantitative study...

Provedor de dados: 42
Autores: COSTA,OSCAR T.F. DA; RAMOS,CLEVERSON A.; DUNCAN,WALLICE P.; LAMEIRAS,JULIANA L.V.; FERNANDES,MARISA N.
ABSTRACT The gill mitochondria-rich cells of the juvenile Amazonian fish Colossoma macropomum were analyzed using light and scanning and transmission electron microscopy after 96 h exposure to 0.04 and 0.2 mM nitrite. Although the number of mitochondria-rich cells decreased significantly in the lamellar epithelium, no decrease was found in the interlamellar region of the gill filament. Nitrite exposure caused significant reduction on the apical surface area of individual mitochondria-rich cells (p &lt; 0.05), with a resulting reduction of the fractional area of these cells in both the lamellar and filament epithelium. Swelling of endoplasmic reticulum cisternae, nuclear envelope and mitochondria were the main changes found in the mitochondria-rich cells....

The green aphid Schizaphis graminum (Rondani) is an important pest of Graminae. Samples of this aphid were collected at three environmentally distinct Brazilian localities, Passo Fundo (RS), Jaguariuna (SP) and Dourados (MS). Alatae and apterous viviparous forms were reared on the BR-35 wheat (Triticum aestivum) strain under controlled laboratory conditions and studied as to their variability in measures of body size and production of progeny. Univariate (ANOVA) and multivariate (canonical discriminant functions) techniques were used to evaluate differences among the three populations. Conspicuous differences between populations were observed in the length of five structures of the alatae and eight of the apterous forms, as well as in offspring production....

Microdesiccates produced from normal human tears display four distinctive morphological components
Provedor de dados: 48
Autores: López Solís,Remigio; Traipe Castro,Leonidas; Salinas Toro,Daniela; Srur,Miguel; Toledo Araya,Héctor.
Desiccation of human tears on glass surfaces results in fern-like crystalloids. This phenomenon has been associated with tear normality (Tear Ferning Test, TFT) and is used as a diagnostic aid to evaluate patients with Dry-Eye disease. However, TFT is focused on the assessment of only a minor fraction of desiccated tear samples and considers only the relative abundance and density of fern-like crystalloids. The aim of this study was to characterize morphologically entire desiccated micro volumes of tears from healthy donors. Tear samples were collected from 23 healthy young adult volunteers. Tear aliquots (1-3 &amp;#956;L) were allowed to dry on glass surfaces under ambient conditions of temperature (15-25°C) and relative humidity (40-45%). Dry samples...

The aim of this study was to evaluate the possible beneficial effects of Catuaba Cristal® (CC), an alcoholic drink made from wine and Erythroxylum catuaba Ar. Cam on testis. Wistar rats either received CC solution (n=8) or water (n=9). Results showed significant body weight reduction within the CC group, although, no weight changes were observed for liver, kidney, testis, epididymis, seminal vesicle and prostate. The volumetric proportion and volume of interstitial tissue and lymphatic space were reduced in the treated group. In the CC group, although the nuclear volume of Leydig cells (LC) decreased, the number of LC per testis increased. These results suggested that CC had no beneficial effect on spermatogenesis of Wistar rats.

Chrysobalanus icaco (abajeru; C.icaco) is recommended in the treatment of diabetes and other clinical disorders. Blood constituents labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this study was to verify the effects of an abajeru extract on the labeling of blood constituents with 99mTc and on the shape of red blood cells (RBC). Blood samples(Wistar rats) were incubated with abajeru extract and the labeling of blood constituents with 99mTc and morphology of RBC were carried out. The results showed significant (P&lt;0.05) alteration of labeling of blood constituents with 99mTc and the morphometry (perimeter/area ratio) of the RBC in presence of the extract. These data suggest that this abajeru extract could alter the labeling of...

Many compounds affect the bioavailability of radiobiocomplexes as radiopharmaceuticals. Ginkgo Biloba extract (EGb) has several effects. The influence of an EGb on the bioavailability of the radiobiocomplex sodium pertechnetate (Na99mTcO4) and on the morphometry of the organs was evaluated. Rats were treated with EGb and Na99mTcO4 was injected. The animals were sacrificed; the radioactivity in the organs was counted. The results showed that EGb altered the Na99mTcO4 bioavailability in the kidneys, liver and duodenum. Morphometric analysis of the organs showed significant alterations (P&lt;0.05), probably caused by metabolites generated by EGb and capable of altering the bioavailability of the Na99mTcO4.

Autores: Monteiro,Juliana Castro; Matta,Sérgio Luis Pinto da; Predes,Fabrícia Souza; Paula,Tarcízio Antônio Rego de.
The present study was carried out to investigate the effects of Rudgea viburnoides infusion on the body biometry and testicular morphometry and stereology of adult Wistar rats. Two groups received the infusion daily at the concentration of 3 or 6 mg/mL for 40 days. The control group received only water. Neither the biometrical parameters nor the tubular diameter and the height of the seminiferous epithelium showed any significant alterations in the treated animals. Leydig cells stereology did not show any significant alterations in the treated animals. These results indicated that R. viburnoides did not cause alterations in body biometry and testicular morphometry.

Entrapment neuropathy is a group of clinical disorders involving compression of a peripheral nerve and interference with nerve function mostly through traction injury. We have investigated the chronic compression of peripheral nerves as an experimental procedure for detecting changes in ultrastructural nerve morphology. Adult hamsters (Mesocricetus auratus, N = 30) were anesthetized with a 25% pentobarbital solution and received a cuff around the right sciatic nerve. Left sciatic nerves were not operated (control group). Animals survived for varying times (up to 15 weeks), after which they were sacrificed and both sciatic nerves were immediately fixed with a paraformaldehyde solution. Experimental nerves were divided into segments based upon their distance...

The semipalmated sandpiper Calidris pusilla and the spotted sandpiper Actitis macularia are long- and short-distance migrants, respectively. C. pusilla breeds in the sub-arctic and mid-arctic tundra of Canada and Alaska and winters on the north and east coasts of South America. A. macularia breeds in a broad distribution across most of North America from the treeline to the southern United States. It winters in the southern United States, and Central and South America. The autumn migration route of C. pusilla includes a non-stop flight over the Atlantic Ocean, whereas autumn route of A. macularia is largely over land. Because of this difference in their migratory paths and the visuo-spatial recognition tasks involved, we hypothesized that hippocampal...

Autores: Silva,E.J.; Felicio,L.F.; Nasello,A.G.; Zaidan-Dagli,M.; Anselmo-Franci,J.A.
Although adrenocorticotropic hormone is generally considered to play a major role in the regulation of adrenal glucocorticoid secretion, several reports have suggested that other pituitary hormones (e.g., prolactin) also play a significant role in the regulation of adrenal function. The aim of the present study was to measure the adrenocortical cell area and to determine the effects of the transition from the prepubertal to the postpubertal period on the hyperprolactinemic state induced by domperidone (4.0 mg kg-1 day-1, sc). In hyperprolactinemic adult and young rats, the adrenals were heavier, as determined at necropsy, than in the respective controls: adults (30 days: 0.16 ± 0.008 and 0.11 ± 0.007; 46 days: 0.17 ± 0.006 and 0.12 ± 0.008, and 61 days:...

Because histopathological changes in the lungs of patients with systemic sclerosis (SSc) are consistent with alveolar and vessel cell damage, we presume that this interaction can be characterized by analyzing the expression of proteins regulating nitric oxide (NO) and plasminogen activator inhibitor-1 (PAI-1) synthesis. To validate the importance of alveolar-vascular interactions and to explore the quantitative relationship between these factors and other clinical data, we studied these markers in 23 cases of SSc nonspecific interstitial pneumonia (SSc-NSIP). We used immunohistochemistry and morphometry to evaluate the amount of cells in alveolar septa and vessels staining for NO synthase (NOS) and PAI-1, and the outcomes of our study were cellular and...

Morphological changes of carotid bodies in acute respiratory distress syndrome: a morphometric study in humans
Provedor de dados: 56
Autores: Vinhaes,E.N.G.; Dolhnikoff,M.; Saldiva,P.H.N.
Carotid bodies are chemoreceptors sensitive to a fall of partial oxygen pressure in blood (hypoxia). The morphological alterations of these organs in patients with chronic obstructive pulmonary disease (COPD) and in people living at high altitude are well known. However, it is not known whether the histological profile of human carotid bodies is changed in acute clinical conditions such as acute respiratory distress syndrome (ARDS). The objective of the present study was to perform a quantitative analysis of the histology of carotid bodies collected from patients who died of ARDS.

ABSTRACT:  Prochilodus argenteus is an endemic fish species from the São Francisco River basin that is of high economic and environmental importance. The present study aimed to contribute with information to the taxonomic identification of  larvae and juveniles of this species. Larvae , obtained from induced spawning of wild animals, were reared in ponds. Individuals were collected daily and classified into larval stages or juvenile phase. Morphological descriptions and morphometric measurements were performed, together with a piece wise linear regression analysis of the body proportions throughout the development process. Individuals in the preflexion stage had a standard length (SL) of 4.48 to 6.64mm, long to moderate body (BH/SL), small to moderate head...

The lacrimal and third eyelid superficial glands produce the aqueous component of the preocular tear film. In this research, morphologic and morphometric assessments of the parenchyma and stroma of both lacrimal glands of healthy adult mongrel dogs were performed. Both lacrimal and third eyelid glands of fourteen dogs were collected, summing fifty-six samples. The macroscopic and morphometric data were statistically analyzed, according to the glandular type (lacrimal and third eyelid superficial glands) and sexual dimorphism (male or female). The lacrimal glands were significantly larger and longer than the superficial glands of the third eyelid. Expressive morphometric differences of interlobular duct, lymphocytic infiltration, interlobular vessels and...

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

The hepatic megakaryocytic cells of New Zealand White rabbit in the intrauterine phase and in the immediate postnatal period were studied. Statistical analysis of the data concerning the cytoplasm and nucleus of those cells, i.e., area, perimeter, maximum diameter, minimum diameter, volume and shape factor, presented significant differences (p&lt;0.01) for F values concerning the life phases studied on15th, 22nd and 29th day of intrauterine life and 10th day of postnatal life, and for F values for animal within each phase. The Tukey’s test showed that most of the parameters studied in the cytoplasm and nucleus of these megakaryocytic cells presented the lowest values on the 15th day of intrauterine life and the highest on the 22nd day of the same phase.

ABSTRACT:  This study aimed to evaluate whether cheese whey associated with transitional milk or not, could serve as a suitable alternative to whole milk for calf rearing. For this, twenty-four male calves of crossbred Holstein-Zebu, were distributed in a completely randomized design with three treatments (8 calves per treatment) and fed for 60 days with one of the following liquid diets: i) 100% whole milk, ii) 50% whole milk and 50% cheese whey, and iii) 30% transitional milk and 70% cheese whey. There was no difference in food intake between treatments. The analysis showed that whole milk replacement did not alter the stomach weight or the ruminal cell proliferation when compared to treatment using 100% whole milk; however, the transitional milk/cheese...

Castor bean hulls (CBH), co-products of castor oil extraction, are high in dry matter (DM) and fiber and are emerging as alternative roughage in sheep feed. This could reduce feed costs since other sources of roughage can be more expensive. The effects of replacing Tifton 85 hay with CBH at 0, 33, 66 and 100% in the diet of sheep on the carcass characteristics, weights and yields of retail cuts and carcass measurements were studied. Twenty-eight non-castrated sheep averaging 7 ± 1.4 months of age with an initial weight of 19.5 ± 4.3 kg were slaughtered after 70 days of confinement. There was a linear decline (P ≤ 0.05) in slaughter body weight, empty body weight, hot and cold carcass weight and longissimus muscle area (LMA) as the percentage of dietary CBH...
