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 …

To achieve a coherent evolutionary theory, it is necessary to account for the effects of the
environment on the process of development. Phenotypic plasticity is the change in the …

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 …

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 …

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

We argue that generalist natural enemies of herbivorous insects provide a major selection
pressure for restricted host plant range. The significance of plant chemistry is discussed in …

Publisher Summary The chapter discusses the use of genotype-by-environment interaction
for crop cultivar development. The chapter begins with definitions of genotype, environment …

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

The topic is reviewed under the following headings:(1) the general potential of mixtures,(2)
disease restriction in mixtures,(3) pathogen evolution in mixtures,(4) the yield advantage …
