| ABSTRACT Sacha inchi (Plukenetia volubilis) is native to the Amazon region and has a high seed content of mono and polyunsaturated fatty acids, making it interesting for the pharmaceutical and cosmetic industry. The purpose of this study was to analyze sacha inchi genetic diversity and describe accessions based on phenotypic characteristics. Fruits and seeds of 25 accessions from the sacha inchi genebank of Embrapa Amazônia Ocidental in Manaus, Amazonas state, were sampled and biometrically measured. The data were subjected to analysis of variance, Mahalanobis distance, canonical correlation, and genetic diversity among and within accessions by analysis of molecular variance (AMOVA). There were significant differences among the means of the analyzed... |

| The aim was to analyze variation in 12 Brazilian and Moroccan goat populations, and, through principal component analysis (PCA), check the importance of body measures and their indices as a means of distinguishing among individuals and populations. The biometric measurements were wither height (WH), brisket height (BH) and ear length (EL). Thorax depth (WH-BH) and the three indices, TD/WH, EL/TD and EL/WH, were also calculated. Of the seven components extracted, the first three principal components were sufficient to explain 99.5% of the total variance of the data. Graphical dispersion by genetic groups revealed that European dairy breeds clustered together. The Moroccan breeds were separated into two groups, one comprising the Drâa and the other the... |

| ABSTRACT The bat Eumops perotis (Schinz, 1821) is broadly distributed in the Americas. Studies on its biology are still scarce and the few studies available are relatively outdated. In the present study, we describe the biology of Eumops perotis in an artificial roost in the municipality of Pindorama, State of São Paulo, southeastern Brazil, which was monitored for 12 months. We captured 50 individuals; 43 adults (34 males and 9 females) and seven juveniles (three males and four females). Nineteen adults were recaptured throughout the year (15 males and four females) during samplings. Males were ~33% heavier than females. Males remained in the roost throughout the year, while females were absent in June, July, and August. The presence of males with scrotal... |

| The principal biometric relations of juvenile Trachypenaeus similis similis and T. constrictus in Guadeloupe were calculated from 1976 to 1978. The examination of these relations yields few differences between the two species. A growth curve was established according to the sequences of modal values; these were determined according to weekly size frequency distributions over three different periods of time. In the zone studied, the growth of young Trachypenaeus is more rapid than that of the young Penaeus. |

| De juin 2002 à juin 2005, 267 syngnathes aiguilles, <Syngnathus acus> Linnaeus, 1758, ont été récoltés dans les eaux tunisiennes: 204 dans Bahiret El Biban (Tunisie méridionale), 24 dans la lagune Sud de Tunis et 39 devant La Goulette (Tunisie septentrionale). Trois types d'études ont été effectués à partir de l’ensemble des variables biométriques: la première repose sur l'analyse de la variance et de la moyenne à l'aide du test "F" de Ficher et du test "t" de Student; la deuxième est fondée sur l’analyse de la multivariance (ANOVA); et la troisième est fondée sur des analyses multidimensionnelles. La première et la deuxième études ont montré des différences significatives dans les variances et les moyennes pour la plupart des caractères examinés,... |

| Le présent travail porte sur l’étude des caractères biométriques de l’huître perlière Pinctada radiata des îles de Kerkennah pour la différenciation entre les populations des deux sites El Kraten et El Jorf à partir d’un pouvoir discriminant des caractères métriques et méristiques. Durant l’année 2007, un total de 2360 et 2422 individus ont été collectés respectivement dans les sites d’El Kraten et d’El Jorf. Les résultats des comparaisons des moyennes et des variances des caractères biométriques à l’aide du test "F" de Fisher et du test "t" de Student plaident en faveur d’une discrimination entre les deux populations. De même, les résultats des analyses multivariées (l’Analyse en Composante Principale (ACP) et l’Analyse Factorielle Discriminante (AFD))... |

| Pour l’étude biométrique de la squille Squilla mantis, un échantillonnage régulier a été réalisé dans le golfe de Tunis, le golfe de Hammamet et le golfe de Gabès de janvier 2005 à décembre 2006. Les équations morphométriques de la squille, dans le golfe de Gabès, ont montré que la croissance relative du telson, celle de la masse totale et celle de la masse éviscérée par rapport à celle du céphalothorax sont caractérisées par une allométrie positive. Par contre, la longueur totale croît négativement par rapport à celle du céphalothorax. Pour le golfe de Hammamet, ces caractères ont une croissance marquée par une allométrie négative à part la masse éviscérée. Les équations morphométriques de la squille du golfe de Tunis ont montré une allométrie positive... |

| La patelle, Patella caerulea Linnaeus, 1758, est un mollusque gastéropode très fréquent sur toutes les côtes rocheuses tunisiennes. Elle expose des traits écologiques et comportementaux complexes qui varient d’un milieu à un autre. Dans cette étude, nous nous proposerons d’analyser la diversité morphométrique de P. caerulea peuplant trois sites rocheux des côtes nord de la Tunisie (Canal de Bizerte, La Goulette et Sidi Rais). Le test t de Student, le test "t" : de pente (tpe) et de position (tpo) ont été utilisés pour la comparaison des pentes et des positions des droites de régressions entre les 3 populations étudiées. A l’échelle globale, les résultats des trois relations allométriques (longueur-hauteur, longueur-largeur et largeur-hauteur), mises en... |

| The main objective of this work is to study some biological aspects of Carcinus aestuarii Northern Sfax (biometry, reproduction, diet), and biochemical contents (water, protein, minerals, and fat). Analysis of metric characteristics of Carcinus aestuarii allowed us to determine the nature of the allometry between the width and différent parts of the body of the crab. For reproduction study, analysis of monthly changes in the gonadosomatic index (GSI) shows that the spawning period of Carcinus aestuarii North Sfax occurs from October to January. The analysis of monthly variations of the hepatosomatic index (HSI), shows that this species used the hepatic reserved to the maturity of gonads. The analysis of monthly variations of the sex-ratio shows that the... |

| Abstract Fig tree (Ficus carica L.) is a fruit of great importance worldwide, being able to be implanted as new source of agricultural variability. The aim of the present work was to characterize the active germplasm bank of fig trees by means of morphological descriptors of 45 fig accessions at the Faculty of Agrarian and Technological Sciences, Campus of Dracena, FCAT / UNESP aiming at the recognition of the quality and genetic variability potential of the species. Thus, their biometric characteristics were evaluated by qualitative and quantitative descriptors of leaves and fruits. Fig tree accessions were characterized by means of the morphological characteristics of leaves and fruits, identifying AGB with high phenotypic variability and well adapted... |

| ABSTRACT The aim of this study was to characterize the seeds quality and the plant development of F1 and F2 generations of hybrid UENF/Caliman 01 papaya, and the relations between the physic-chemical and physiological quality of seeds, vegetative and reproductive development of plants in the field for 360 days, and fruit quality. The relative contribution (Cr %) to the genetic divergence for each characteristic was estimated. For those with higher importance for each group (Cr = 25%), the Pearson correlation and the canonical correlation analysis were applied. The F1 seeds showed higher physic-chemical and physiological quality, with greater length (0.55 cm), sugar and lipid levels (5.13 and 11.58 mg g-1, respectively), germination and normal seedlings... |
