| The variations of the hyoid bone has a great significance for surgical procedures of neck region, and in forensic medicine for evidence of strangulation or hanging, which causes fractures. The aim of this study was to investigate the morphological and morphometrical variations of the hyoid bone in Anatolian population. A total of 60 adult larynx specimens (46 male, 14 female) were dissected to identify morphological and morphometrical variations of hyoid. The infrahyoid muscles and thyrohyoid membrane were cut and ligamentous structures of bone were removed. The variations of shape of the hyoid were classified into six types: A (U-shaped) hyoid bone observed in 31.7 % (19 bones), a horseshoe-H-type in 10 % (6 bones), a B-type hyoid in 31.7 % (19 bones), a... |

| The maxillary sinus varies according to age, however there are limited studies that have illustrated its 3D form over time. This study aimed to classify the maxillary sinus by the shape, number of septa and scallops in a 1 to 25 year age group, utilising computerized tomography (CT) scans and 3D reconstruction. CT scans (n=480) were reviewed from the picture archiving and communication system (PACS) of the state and private hospitals in Pietermaritzburg and Durban KwaZulu- Natal (KZN), South Africa. The sample consisted of 276 males and 204 females, 1-25 years and of two population groups, black African and white. SLICER 3D (www.slicer.org) was utilised in order to reconstruct a 3D model of the sinus. Morphological traits such as the presence of the sinus,... |

| We investigated intraspecific variation of the Snowtrout, Schizothorax richardsonii on the basis of morphometric characters. Altogether, 217 specimens were collected from four rivers in the Western and Central Indian Himalaya. A truss network was constructed by interconnecting 14 landmarks to yield 31 distance variables that were extracted from digital images of specimens using tpsDig2 and PAST software. Transformed truss measurements were subjected to univariate analysis of variance, factor analysis and discriminant analysis. All variables exhibited significant differences between the populations. Altogether 86.6% of the specimens were classified into their original populations (82.9 % under a ‘leave-one-out’ procedure). With factor analysis measurements... |

| In tropical littoral environments, suspended organic matter favors the presence of sessile filter feeder organisms such as sponges, over those predominantly phototrophic such as algae and corals. In the Santa Marta area in the Colombian Caribbean, productivity is enhanced by alternating pulses of coastal upwelling and continental runoff, resulting in an important diversity and abundance of sponges. Species of the genus Ircinia ( I. campana, I. felix and I.strobilina) are conspicuous and abundant in the rocky and reef biotopes of the area. To establish the influence of predominant environmental conditions on the distribution of these three species, their density, size and microhabitat preference, their form and color, the occurrence of predation signs, the... |

| Abstract Solitary bees Apidae: Centridini are important pollinators of Malpighia emarginata DC. Malpighiales: Malpighiaceae. However, there are few studies on the characterization of populations of this species in areas with orchards and their surroundings. This study analyzed the morphometric variability and sexual dimorphism of Centris tarsata Smith, sampled in artificial nests installed at four different vegetation types. The right forewings of 168 individuals were dissected, photographed, and the images processed in TpsUtil and brought to the TpsDig2 version 2.12 for plotting 18 landmarks by geometric morphometrics. Data were analyzed through Principal Components Analysis PCA, Canonical Variables CV, and cross-validation in order to test the correct... |

| The effect of moisture content on some physical properties of Bush Mango (Irvingia gabonensis) nut was studied at four moisture levels in the range of 7.52% - 20.6% (d.b). Results showed that the length, width and thickness of nut increased from 37.84 to 50.16 mm, 30.23 to 42.62 mm and 19.25 to 28.15 mm respectively, as moisture content increased in the above range. Nut sphericity decreased from 76.2% to 69.5% as moisture content increased. One thousand seed weight, bulk density, true density and angle of repose increased from 6.634 to 9.158 kg, 756.7 to 1095 kgm-3, 984.4 to 1095kgm-3 and 25.3 to 38.9o respectively, in the above moisture range. Static coefficient of friction on different surfaces increased in the order of fiber glass (0.378 to 0.394),... |

| ABSTRACT A study on relative growth, sexual dimorphism and ontogenetic trajectory was carried out in a population of the aeglidAegla marginata coming from Barrinha River, Iguape River Basin, Tunas do Paraná, Paraná State, Brazil. The size the of morphological sexual maturity was estimated for males and females. The analysis of sexual dimorphism and ontogenetic trajectory were performed using geometric morphometric technique. Males reach maturity with 10.58 mm of carapace length (CL) and females with 10.38 mm CL. Sexual size dimorphism was only visible among adults, with males reaching larger sizes. This is probably related to the reproductive strategy of males. However, sexual shape dimorphism was found for both juveniles and adults: the posterior region... |
