Abstract Beavers (Castor fiber, Castor canadensis) are one of the most influential
mammalian ecosystem engineers, heavily modifying river corridor hydrology …

The functional response of a consumer is the relationship between its consumption rate and
the abundance of its food. A functional response is said to be of type I if consumption rate …

In this work, George C. Williams--one of evolutionary biology's most distinguished scholars--
examines the mechanisms and meaning of natural selection in evolution. Williams offers his …

We present a handy mechanistic functional response model that realistically incorporates
handling (ie, attacking and eating) and digesting prey. We briefly review current functional …

Abstract The Eurasian and North American beavers aresimilar in their ecological
requirements, andrequire water deep enough to cover the entranceto their lodge or burrow …

We suggest that selective foraging alters feedbacks between plants and decomposers and
between plants and herbivores. Plant tissue chemistry is an important link between …

Whether herbivores are food limited and compete interspecifically for food has been
debated by population/community ecologists. To examine this proposition, a mechanistic …

Abstract In his recent Annual Review of Psychology article, Snowdon (1983) discussed the
synthesis of ethology and comparative psychology. A similar synthesis of behavioral ecology …

A particular linear programming model is constructed to predict the diets of each of 14
species of generalist herbivores at the National Bison Range, Montana. The herbivores …

Summary The summer (May–September) time budgets of 14 generalist herbivore species
living in the same grassland environment are presented in terms of various component …
