Des profondeurs mysterieuses du lac Vostok, en Antarctique, aux lacs des plaines inondables tropicales, les ecosystemes lacustres partagent de nombreuses caracteristiques. Comment ont-ils ete formes? Les " lacs morts " peuvent-ils être ressuscites? Comment les lacs nous renseignent-ils sur le passe et le present de la Terre? Warwick Vincent explique les principaux aspects de la science des lacs, la limnologie. À l'aide d'exemples tires de partout dans le monde, il decrit les caracteristiques environnementales et l'ecologie des lacs, ainsi que la valeur qu'ils ont pour la societe. Soulignant l'importance de preserver ces ecosystemes complexes, il examine les effets du climat, des saisons, de la salinite et d'autres facteurs sur la biodiversite des lacs, ainsi que les menaces que representent la croissance des populations humaines et les changements climatiques."--Page 4 de la couverture. "Qu'est ce qu'un lac? À premiere vue, cela semble être une question facile : un lac est tout simplement une etendue d'eau entouree de terres. Mais il existe bien d'autres façons plus interessantes de considerer la nature et la signification des lacs."--Site de l'editeur.

"From the mysterious depths of Lake Vostok, Antarctica, to tropical floodplain lakes, inland bodies of water share many distinctive features. How are they formed? Can 'dead lakes' be revived? What can lakes tell us about Earth's past and present? Warwick Vincent explains the main aspects of lake science, or limnology. Using examples from across the world, he describes the environmental features and ecology of lakes, and their value to society. Outlining the mportance of sustaining these complex ecosystems, he considers the impact of factors such as climate, seasons, salinity, and oxygen on lake biodiversity, and the threats imposed by rising human populations and climate change." --Inside cover.
