"Une véritable course contre la montre est engagée : celle du développement durable face à la montée des changements environnementaux planétaires. Le climat actuel est sans doute le plus chaud qu'ait connu la Terre depuis 10 000 ans, avec une concentration en CO2 sans précédent depuis près d'un million d'années. Comme la fenêtre d'un réchauffement limité à 2°C est en train de se refermer, la biosphère et l'homme vont devoir s'adapter à des conditions entièrement nouvelles, caractérisées en particulier par des vagues de chaleur, des sécheresses et des précipitations intenses. Comment préserver la biodiversité et les écosystèmes ? Comment augmenter la production alimentaire tout en limitant les émissions de gaz à effet de serre ? Comment survivre dans les sociétés traditionnelles ? Quel avenir pour l'agriculture, la forêt et la pêche ? Quel devenir pour nos territoires ? Autant de questions auxquelles la communauté scientifique tente d'apporter des réponses. Issu de l'atelier de réflexion prospective Adaptation de l'agriculture et des écosystèmes anthropisés au changement climatique (ADAGE) réunissant près de 150 experts, cet ouvrage offre une synthèse concernant les approches, les secteurs (sols, eau, sécurité alimentaire, compétitivité, territoires...) et les défis de l'adaptation. C'est à ce large tour d'horizon qu'il invite, en posant aussi en toile de fond la question de notre avenir commun au cours du XXIe siècle et au-delà."

Biological Diversity and Sustainable Resources Use is a very interesting volume, including attractive overviews and original case studies mainly focused on socio-economical effects of the right management of the ecosystems biodiversity, as well as on the useful integration between human activities and environmental responses. Ecological, medical and historical aspects of the sustainable development are also discussed in this book which consists of articles written by international experts, offering the reader a clear and extensive view of the present condition in which our planet is.

A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities ? What other scientific areas might serve as a guiding framework ? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology’s various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.
