Domestication through the Centuries: Darwin’s Ideas and Dmitry Belyaev’s Long-Term Experiment in Silver Foxes Gayana
Bidau,Claudio J.
The problem of the origin of domestic animals and plants, and the means by which they were produced along human history, were of deep interest to Charles Darwin who considered domestic breeding ‘one grand experiment’ in evolution. In frst place, he elaborated an analogy between artifcial selection, by which breeders obtained desired characters in domestic species, and natural selection, the powerful force driving evolution in nature. At the same time, Darwin distinguished two processes within artifcial selection: methodical and unconscious selection. He attached great importance to the latter since it could produce gradual unexpected changes in association with those characters that were consciously selected for. Although the analogy natural/artifcial...

The Role of Economic and Social Factors Driving Predator Control in Small-Game Estates in Central Spain Ecology and Society

As a consequence, predators have been frequently controlled by game managers, which has negatively affected many predator populations worldwide. The understanding of human-wildlife conflicts requires a multidisplicinary framework that is rarely considered. We aim to evaluate the attitudes and behavior of game managers with regard to predator management in central Spain, as well as to explore factors that lead to these attitudes and behavior. Data were gathered through face to face interviews with game managers from 59 small-game hunting estates within central Spain. Predator...
