Les populations de cerfs, de chevreuils et de sangliers explosent en Europe, générant des difficultés de gestion en ville et en milieu rural. Qui commet les dégâts : l’homme qui détériore l’environnement naturel de la faune dans son intérêt économique ou bien la faune qui prélève les productions humaines pour survivre ? Selon l'auteur, l’équilibre entre les Ongulés et les milieux forestier ou agricole repose sur la connaissance du comportement des animaux et sur la régulation par la chasse, sans oublier la mortalité naturelle due à la réapparition des grands prédateurs. La solution résiderait avant tout dans la concertation entre usagers de la nature.
Public : chasseurs, forestiers, agriculteurs et passionnés qui recherchent l’équilibre entre le grand gibier et son milieu.
Genetic plant improvement aims to unite in a same genotype the variety and the maximum number of favourable genes for the traits to be improved. But which tools are used to achieve this? This book answers this question and shows that, since domestication, plant breeding has always been governed by genetic engineering.
Partly instrumentalised by the policies, the nature conservation movements and the economists, ecology is the vector for many perceived ideas. The ecologists themselves fuel the debate dramatising the future of the planet, in the belief that they are giving legitimacy to their discipline. But are the resources used for ecological research in line with the anxieties and appeals from society and managers? This work is the testimony of an ecologist at the heart of this multi-discipline research.
