Such individual differences in ways of coping with stress are relevant both in biomedicine, since different personalities may experience a different stress and disease vulnerability, and in behavioural ecology, since their adaptive value and evolutionary maintenance are the subject of debate. However, the precise way in which individual stress differences and personalities are linked is unclear. Here we provide an updated overview of this covariation across different species and taxa, consider its functional significance and present working hypotheses for how behavioural and physiological responses to stress might be causally linked, affecting life-history traits such as dispersal and life-span [Current Zoology 56 （6）： 728-740, 2010].展开更多

For each animal, the following biometrical measurements were considered： withers height, chest height, chest depth, trunk length, rump length, ischium width of the rump, ear and nose length, chest and cannon circumference. Results showed that sexual dimorphism was not present; however two morphological groups of Basset Hound with some differences were found. The first group consisted of animals with high and broad chest, while the second one was more compact, with more pronounced nose and ears. Considering breed health, it would be interesting to select the subjects of the first group since showing an anatomical less susceptible to some conformational disorders typical of the breed. On the contrary, focusing our interest on the breed hunting attitude, the second group would have some characteristics more suitable for this purpose.展开更多
