Abstract: 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.
Contents: Alternative theories of trophic interaction -- Direct measurements of the functional response -- Indirect evidence : food chain equilibria -- How gradual interference and ratio dependence emerge -- The ratio dependence controversy -- It must be beautiful.
