Ethologie animale. Une approche biologique du comportement

Anne-Sophie Darmaillacq, Frédéric Lévy

Published in 2015

What is ethology, the ideas behind it and its methods? How does an animal inhabit its space, make use of available food resources and build its social world? What are the cognitive processes at work in this? How can personality explain behaviour? Written by specialists from different fields but in an intentionally accessible and explanatory way with the help of numerous illustrations, this book offers an overview of ethology grounded in analysis of cutting-edge research in ethology.

Stress and welfare: two complementary concepts that are intrinsically related to the animal's point of view

Veissier I., Boissy A

Published in 2007

The closely associated concepts of welfare and stress may be considered as opposites since welfare cannot be achieved under stress and vice versa. Stress was first considered as an unspecific response to any challenge taxing the organism's resources where the HPA axis plays a central role. Along the same lines, welfare was considered as the state of an individual on a continuum between poor and good depending on the efforts required to adapt to the environment. However, these views cannot explain opposite results such as up- vs. down-regulation of the HPA axis and hypo- vs. hyper-behavioural reactivity under chronic stress. ... It is therefore suggested that the discrepancies found in the literature in terms of responses of the HPA axis or modification of behaviour under aversive conditions may stem from differences in the way a situation is evaluated. It is argued that stress comes from the animal's evaluation of the outcome of a situation, and that welfare is the state resulting from that evaluation.
