Abstract:
... In the cases of transgender and gender non-conforming people, a description of their physical remains, including biological sex, may have little correlation with their social identity, delaying and often confusing the issue of identification. Some transgender individuals have sought to alter their physical appearance in order to better reflect their gender. One group of surgical modifications for ...

Abstract:
... The St. Lawrence River, at Cornwall Ontario, has accumulated sediment contaminants, mainly mercury (Hg) and polychlorinated biphenyls (PCBs), from industrial point sources over many years. Although those sources are past, the river at Cornwall remains an Area of Concern (AOC). Because of remediation and other changes in the AOC, improved knowledge of contaminants in wild-fish and their putative li ...

Fourteen body measurements of 132 adult female camels belonging to three populations Guerzni (60), Khouari (28), and Marmouri (44) reared in 38 herds of 8 provinces of Southern Morocco were studied to identify homogeneous groups according to their conformation. The measurements were chest girth (CG), hump girth (HG), height at withers (HW), body length (BL), fore limb length (FLL), chest width (CW ...

And, because life-history traits can vary across species, correct identification is a mandatory step before being used as evidence. Adult flesh flies are extremely similar in general appearance, which causes difficulty in species ...

Abstract:
... Dietary intervention is commonly used for weight loss or to improve health, as diet-induced obesity increases the risk of developing type 2 diabetes, hypertension, cardiovascular disease, stroke, osteoarthritis, and certain cancers. Various dietary patterns are associated with effects on health, yet little is known about the effects of diet at the tissue level. Using untargeted metabolomics, this ...

Abstract:
... The ability to identify individuals within a population is often essential for a detailed understanding of the ecology and conservation of a species. However, some species, including large parrots, are notoriously difficult to catch and mark for individual identification. Palm cockatoos (Probosciger aterrimus) are a large, poorly understood species of parrot which are likely in severe decline with ...

Abstract:
... Current quantitative methods for estimating ancestry and sex from skulls typically require substantial manual data collection and specialized recording equipment, which can limit analysis to the laboratory. This limitation could be addressed by establishing a faster, more user-friendly, and automatic data protocol as investigated in the current study using elliptical Fourier analysis (EFA). Ancest ...

Abstract:
... A method was developed for determining the age and sex of the water vole (Arvicola amphibius L.) based on the measurements of the pelvic limb bones. The material was obtained from captive-bred animals of a known age. By using discriminant analysis, classification functions were found for dividing the animals of the sample analyzed (n = 56) by sex and age with an accuracy equal to one year. Testing ...

Three studies adapted the Monash Dog-Owner Relationship Scale (MDORS) to permit assessment of human-cat interactions as perceived by the cat’s owner. In Study 1293 female cat owners completed a modified version of the MDORS, where ‘dog’ was replaced with ‘c ...

Abstract:
... Conspecific brood parasites lay eggs in nests of other females of the same species. A variety of methods have been developed and used to detect conspecific brood parasitism (CBP). Traditional methods may be inaccurate in detecting CBP and in revealing its true frequency. On the other hand more accurate molecular methods are expensive and time consuming. Eadie developed a method for revealing CBP b ...

The traditional clinical methods for cervical cancer screening are invasive and limited in terms of cost and time. There is an unmet clinical need for new methods to aid clinicians in the rapid screening and auxiliary diagnosis of cervical precancer. Recently, breath analysis has become an attractive approach fo ...

Abstract:
... The African cichlid fishes show great diversity in mating displays and reproductive strategies, yet species differences in genital morphology have been little studied. Observational notes have described broad sex differences in external genital shape between males and females, but these differences have not been quantified. We examined three aspects of genital morphology (relative anogenital dista ...
