How ecological niche breadth evolves is central to adaptation and speciation and has been
a topic of perennial interest. Niche breadth evolution research has occurred within …

Ecology Letters (2011) 14: 948–958 Abstract Many generalist populations are composed of
specialised individuals, whose niches are small subsets of the population niche. This …

Resource competition is thought to play a major role in driving evolutionary diversification.
For instance, in ecological character displacement, coexisting species evolve to use different …

Habitat fragmentation, an important element of current global change, has profound
repercussions on population and species extinction. Landscape fragmentation reduces …

A species's niche width reflects a balance between the diversifying effects of intraspecific
competition and the constraining effects of interspecific competition. This balance shifts …

Vertebrates' diets profoundly influence the composition of symbiotic gut microbial
communities. Studies documenting diet‐microbiota associations typically focus on univariate …

Much research has focused on identifying species that are susceptible to extinction following
ecosystem fragmentation, yet even those species that persist in fragmented habitats may …

There is extensive evidence that some species of ecological generalists, which use a wide
diversity of resources, are in fact heterogeneous collections of relatively specialized …

Apex predators are often assumed to be dietary generalists and, by feeding on prey from
multiple basal nutrient sources, serve to couple discrete food webs. But there is increasing …

Dietary diversity often varies inversely with prey resource abundance. This pattern, although
typically measured at the population level, is usually assumed to also characterize the …
