Synopsis

Understanding the functioning of ecosystems requires the understanding of the interactions between consumer species and their resources. How do these interactions affect the variations of population abundances? How do population abundances determine the impact of predators on their prey? The view defended in this book is that the "null model" that most ecologists tend to use is inappropriate because it assumes that the amount of prey consumed by each predator is insensitive to the number of conspecifics. The authors argue that the amount of prey available per predator, rather than the absolute abundance of prey, is the basic determinant of the dynamics of predation. This so-called ratio dependence is shown to be a much more reasonable "null model."

À propos de l'auteur

Roger Arditi is a distinguished professor at AgroParisTech in Paris, France. He works for INRA, the French National Institute for Agricultural Research, in the research unit of Ecology and Evolution at University Pierre et Marie Curie. His theoretical and experimental work is focused to basic questions of predation dynamics and applied work addresses agroecological problems.

Lev R. Ginzburg has been a professor of ecology and evolution at Stony Brook University since 1977. He has published widely on theoretical and applied ecology, population genetics, and risk analysis. Ginzburg is co-author, with Mark Colyvan, of the popular title Ecological Orbits: How Planets Move and Populations Grow, published by Oxford University Press in 2004.
