After a brief introduction to spider biology, the author considers the following topics in depth: food limitation; competitionist views of spider communities; the competitionist paradigm; interspecific and intraspecific competition; effects of abiotic factors and natural enemies on population density; the impact of spiders on insect populations; the effect of the physical structure of the habitat on spider populations; and experimental evidence for indirect effects in the ecological webs of spiders. This book will be an essential reference for all ecologists wishing to learn more about the ecology of a major terrestrial predator and the use of field experimentation as a powerful technique to test ecological hypotheses.
