Behavioural ecologists increasingly recognise spatial memory as one the most influential cognitive traits involved in evolutionary processes. In particular, spatial working memory (SWM), i.e. the ability of animals to store temporarily useful information for current foraging tasks, determines the foraging efficiency of individuals. As a consequence, SWM also has the potential to influence compe...

The link between callous-unemotional (CU) traits in youth and delinquent, aggressive and violent behavior is well-replicated in the literature. However, the mediating effects of violence exposure on this relationship are unclear. The current study addresses this important gap in the literature with a sample of 88 detained, primarily ethnic minority adolescent boys (M age = 15.57; SD = 1.28). Re...

background: mercury is widespread and persistent in the environment. one organic form of mercury, methylmercury (mehg), can accumulate in the food chain in aquatic ecosystems and lead to high concentrations of mehg in fish, which, when consumed by humans, can result in an increased risk of adverse effects. currently, the joint fao/who expert committee on food additives (jecfa) has established p...

Hair dysplasias are congenital or acquired alterations which often involve the hair shaft. Hair shaft abnormalities are characterized by changes in color, density, length and structure. Hair shaft alterations often result from structural changes within the hair fibers and cuticles which may lead to brittle and uncombable hair. The hair of patients with hair shaft diseases feels dry and looks lu...

Studying genetic parameters and genetic changes in Santa Ines sheep is important, because it is the commonest breed in Brazil. This study obtained genetic data from 37,735 pedigree records of lambs over 12 years (2003-2014) from 33 flocks in 10 Brazilian States; 11,851 records of performance were available. (Co)variance components, genetic parameters and breeding values estimates were obtained ...

This is a book, designed for popular consumption, that lists a number of normal characters held to be inherited in man. Many traits are scarcely "treasures," as might be inferred from the title. They pertain chiefly to physical characters, especially those of the face and other readily inspected areas. Much of the material would appear to have been obtained from students in the author's class o...

People increasingly have their genomes sequenced and some of them share their genomic data online. They do so for various purposes, including to find relatives and to help advance genomic research. An individual’s genome carries very sensitive, private information such as its owner’s susceptibility to diseases, which could be used for discrimination. Therefore, genomic databases are often anony...
