Morphometric analysis of Capitella capitata (Polychaeta, Capitellidae) Iheringia, Sér. Zool.
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...

Morphological characterization and sex-related differences of the mandible of the armadillos Chaetophractus vellerosus and Zaedyus pichiy (Xenarthra, Dasypodidae), with consideration of dietary aspects Iheringia, Sér. Zool.
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....

Geographic distribution and morphological variation in Mimon bennettii (Chiroptera, Phyllostomidae) Iheringia, Sér. Zool.
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...

Morphometric variability in populations of Palaemonetes spp. (Crustacea, Decapoda, Palaemonidae) from the Peruvian and Brazilian Amazon Basin Iheringia, Sér. Zool.
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...

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.

Body shape variation in meiotic gynogenetic and triploid sea bass, Dicentrarchus labrax ArchiMer
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...

Relations entre l’état d’une ressource et son exploitation via la compréhension et la formalisation des interactions de socio-écosystèmes. Application à la palourde japonaise (Venerupis philippinarum) du bassin d’Arcachon. ArchiMer
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...

Genetic parameters of in-vivo prediction of carcass, head and fillet yields by internal ultrasound and 2D external imagery in large rainbow trout (Oncorhynchus mykiss) ArchiMer
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. DNA-pedigreed all-female rainbow trout Oncorhynchus mykiss (n =...

Le complexe «Dinophysis acuminata»: identification des espèces le long des côtes françaises ArchiMer
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.

Tests and jaws’ morphological patterns of regular sea urchin Paracentrotus lividus (Lamarck, 1816) in relation to environmental conditions ArchiMer
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...

Shil,Subrata Kumar; Quasem,Md. Abul; Rahman,Mohammad Lutfur.
A histological and morphometric study was conducted to evaluate the seasonal testicular variations in the adult Japanese quail (Coturnix coturnix japonica) in Bangladesh. The weight of birds and testes, volume, length, circumference, seminiferous tubule diameter, circumference and height of germinal epithelium of testes were measured. Sections of testes obtained from studied birds were stained with H&E and images were taken by J software. Weight and volume of paired testes of quails significantly heavier (P<0.05) in long day period of summer and rainy season (March ­ September) than the short day period of autumn and winter (October ­ February). Seasons had no significant effect on live weight gain of quails. The weight and diameter of testes or...

Corrêa,L. B. N. S; Contreiras,E. C; Daleprane,J. B; Boaventura,G. T; Figueiredo,M. A; Chagas,M. A.
The contents of soybean can modify the structure of the reproductive system, especially, when consumed for prolonged periods. In this study, we evaluated the effects of the consumption of transgenic soybean on rat penis morphology after prolonged use. Wistar rats (n = 30) were divided into three groups according to diet: Transgenic Soybean (TS) group, Organic Soybean (OS) group and Control (C) group. After 455 days of intake, the rats were sacrificed and the penises were excised and fixed in formalin for subsequent histological processing. The samples were stained with hematoxylin and eosin, Weigert’s resorcin-fuchsin stain, and picrosirius red with polarization. The images were scanned for the histomorphometric analyses of the corpora cavernosa, corpus...

Morphometric Changes in Talus of Club Foot A Gross Observation in Human Foetuses International Journal of Morphology
Fazal-ur-Rehman,; Faruqi,Nafis A.
Both the feet of six human foetuses of different age groups having unilateral club feet, were dissected for morphological study. Six morphometric parameters considered for comparing gross anatomical changes in normal and deformed feet, were 1-Maximum length of the talus, 2-Longitudinal dimension of head of talus, 3-Anterior trochlear breadth, 4-Maximum medial talar height, 5-Talar neck and calcaneal angle, 6-Talocalcaneal angle. All the foetuses with congenital club feet have almost similar deformity of foot skeleton. The gross anomalies observed were the smaller size of club foot talus and increased medial and planter deviation of a stunted, misshapen head and neck region. A medial plantar subluxation of the navicular bone with a consequent deformity of...
