Исследовано влияние гранулометрического состава грунта на морфоструктуру особей Zostera marina L. Выявлена зависимость морфометрических параметров материнских и дочерних побегов от содержания гранулометрических фракций. Исследуемые параметры объединены в три группы по степени зависимости от процентной доли фракций: 1) вес и размерные характеристики материнского и дочерних побегов; 2) признаки подземной сферы и вегетативного размножения; 3) площадь поверхности листьев. |

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.... |

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. |

Recurrent blooms of Ostreopsis cf. ovata have been reported in Brazil and the Mediterranean Sea with associated ecological, and in the latter case, health impacts. Molecular data based on the D1–D3 and D8–D10 regions of the LSU rDNA and ITS loci, and the morphology of O. cf. ovata isolates and field populations from locations along the Brazilian tropical and subtropical coastal regions and three oceanic islands are presented. Additional ITS sequences from three single cells from the tropical coast are provided. Toxin profiles and quantities of PLTX and their analogues; OVTXs; contained in cells from two clonal cultures and two field blooms from Rio de Janeiro were investigated. Morphology was examined using both light and epifluorescence microscopy.... |

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... |

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 =... |

The aim of the study was to establish morphometrically the infraorbital foramen (IOF) location in the sagittal and transversal plan of the skull and to analyze the variations, as well as verifying the symmetry with the contralateral IOF. 210 skulls were analyzed and as exclusion criterion, were not analyzed skulls of children. Digital paquimeter was used and had been carried through two bilateral measures: a)sagittal measure; from infraorbital margin until the superior margin of the IOF; b) transversal measure, of the lateral margin of piriformis opening until the medial margin of the IOF, using the transversal plan. These measures had formed an angle of 90 between itself. The data were analyzed by the Kolmogorov-Smirnov to verify the Gaussian distribution... |

The mandibular incisive canal (MIC) is a continuation of the mandibular canal, anterior to the mental foramen, containing the neurovascular bundle of the teeth in anterior mandibular segment. The aim of this study was to calculate the prevalence and analyze the morphometric parameters of MIC in a Chilean population through digital panoramic radiographs. A cross-sectional study was performed using 500 digital panoramic radiographies of adult individuals. The prevalence of MIC was set in different sexes, age groups and proximity to teeth; in addition to the morphometric parameters of length, width (diameter) and distances of MIC to dental element and the mandibular base. General MIC prevalence was 53 % (265 cases), 49.9 % in women and 57 % in men. In the age... |

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, Weigerts resorcin-fuchsin stain, and picrosirius red with polarization. The images were scanned for the histomorphometric analyses of the corpora cavernosa, corpus... |

The aim of this study was to evaluate the effects of maternal protein and energy restriction during lactation, analyzing on morphological dimensions whether there was catch-up growth through normative nutrition restored, as well as on mechanical axis of femur of the offspring at adulthood. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard laboratory diet containing 23 % protein, 2) protein-energy restricted group (PER) - free access to an isoenergetic, protein-restricted diet containing 8 % protein, and 3) energy-restricted group (ER) fed with restricted amounts of a standard laboratory diet. At weaning, all pups were separated of dams and received free access to a standard... |

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... |
