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 …

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 …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

Studies of spatial variation in the environment have primarily focused on how genetic
variation can be maintained. Many one‐locus genetic models have addressed this issue …

The relationship between oviposition preference and growth, survival, and reproduction of
offspring is the crux of the problem in the evolution of host associations between …

The effects of species declines and extinction on biotic interactions remain poorly
understood. The loss of a species is expected to result in the loss of other species that …

This volume presents the latest research on herbivores, aquatic and terrestrial mammals
and insects. The Second Edition, written almost entirely by new authors, effectively …

Co‐extinctions are increasingly recognized as one of the major processes leading to the
global biodiversity crisis, but there is still limited scientific evidence on the magnitude of …

An absence of genetic variance in traits under selection is perhaps the oldest explanation for
a limit to evolutionary change, but has also been the most easily dismissed. We review a …
