As experimental organisms, spiders offer ecologists a unique opportunity to examine the concept of the ecological community and the role that field experimentation can play in evaluating theories of population and community ecology. In this book, David Wise provides a balanced critique of field experiments designed to uncover details of spider ecology, with the dual aim of clarifying the ecology of these fascinating organisms and providing insight into the advantages and challenges of performing field experiments with a predator ubiquitous in terrestrial ecosystems.
