The evolution of" niche breadth," or" niche width," was a more popular topic in the
evolutionary ecological literature of the 1960s and 1970s than it has been recently (109 …

Parasitoids and predators of herbivores have evolved and function within a multitrophic
context. Consequently, their physiology and behavior are influenced by elements from other …

There are many different types of organisms in the world: they differ in size, physiology,
appearance, and life history. The challenge for evolutionary biology is to explain how such …

Insects are by far the most diverse group of organisms on Earth; estimates of their current
diversity range as high as 30 million species (58). A large fraction of these species feed on …

My objective here is to provide a comprehensive review of recent empirical and theoretical
work on antipredator decision making. The ways in which predators influence the behavioral …

The body mass (or fat reserves) maintained by a wintering bird can be viewed as a trade—
off between the risk of starvation and the risk of predation. This follows from the fact that fat …

Animals commonly choose among habitats that differ both in foraging return and mortality
hazard. However, no experimental study has attempted to predict the level of increase in …

In this paper, we develop a series of models for predicting optimal egg size and clutch size
in different environments and for different maternal phenotypes. The models investigate the …

Sexual selection depends on differential patterns of mate preference and choice. Little
attention has been paid, however, to the manner in which individuals acquire information …

Parasitoids display remarkable inter-and intraspecific variation in their reproductive and
associated traits. Adaptive explanations have been proposed for many of the between-trait …
