L’eau est un élément essentiel à la survie de la vie sur terre, qui contient des minéraux importants pour l’homme, les plantes et la vie aquatique. L’eau, ressource naturelle de premier ordre et bien national précieux, est le principal constituant de l’écosystème. L’eau est un solvant universel et la substance la plus abondante sur terre. Environ 2 % de l’eau de la planète est douce, mais 1,6 % est emprisonné dans les calottes polaires et les glaciers. Un autre 0,36 % se trouve sous terre dans les aquifères et les puits. Par conséquent, seulement 0,036 % de l’eau totale de la planète est accessible dans les lacs et les rivières. Un nombre croissant de contaminants pénètrent dans les réserves d’eau en raison de l’industrialisation et de l’activité humaine. Toute modification physique, chimique ou biologique de la qualité de l’eau qui nuit aux organismes vivants ou rend l’eau impropre aux usages souhaités est une pollution de l’eau.

  • Water from a Transdisciplinary Perspective
    Ana Isabel Pereira Cardoso / Teresinha M. Gonçalves
    Life in cities has distanced human beings from nature and made it difficult to understand the ecology of life dependent on the environment. Urban water collection and distribution processes contribute significantly to the fragmentation of knowledge and the vital recognition of the water cycle. Without the effective participation of the subject in environmental actions, it is no...

  • Modeling Populations of Adaptive Individuals
    Bret C. Harvey / Steven F. Railsback
    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...

  • Physiological Ecology
    Carlos Martínez del Rio / William H. Karasov
    Unlocking the puzzle of how animals behave and how they interact with their environments is impossible without understanding the physiological processes that determine their use of food resources. But long overdue is a user-friendly introduction to the subject that systematically bridges the gap between physiology and ecology. Ecologists--for whom such knowledge can help clarif...
  • Critical Transitions in Nature and Society
    Marten Scheffer
    How do we explain the remarkably abrupt changes that sometimes occur in nature and society--and can we predict why and when they happen? This book offers a comprehensive introduction to critical transitions in complex systems--the radical changes that happen at tipping points when thresholds are passed. Marten Scheffer accessibly describes the dynamical systems theory behind cr...
