Ecology Letters (2010) 13: 383–393 Abstract The extent to which behavioural choices reflect
fine‐tuned evolutionary adaptation remains an open debate. For herbivorous insects, the …

In recent years, there have been over 50 comparative analyses carried out in which social or
ecological variables have been used to explain variation in whole brain size, or a part …

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 …

Ecological specialization is a fundamental and well‐studied concept, yet its great reach and
complexity limit current understanding in important ways. More than 20 years after the …

Abstract Heliothine moths (Lepidoptera: Heliothinae) include some of the world's most
devastating pest species. Whereas the majority of nonpest heliothinae specialize on a single …

Divergent natural selection has been shown to promote speciation in a wide range of taxa.
For example, adaptation to different ecological environments, via divergent selection, can …

Generalist species are more successful than specialists in anthropogenically modified
environments or in environments in which they have been introduced, but the nature of the …

Phytochemical variation among plant species is one of the most fascinating and perplexing
features of the natural world and has implications for both human health and the functioning …

Speciation often involves the evolution of multiple genetic-based barriers to gene flow
(ie,“coupling”). However, barriers may exhibit a diversity of evolutionary interactions during …

Specialist species, using a narrow range of resources, are predicted to be more efficient
when foraging on their preferred food than generalist species consuming a wider range of …
