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 …

Evolution is the hallmark of life. Descriptions of the evolution of microorganisms have
provided a wealth of information, but knowledge regarding “what happened” has precluded …

Stable isotope analysis has emerged as one of the primary means for examining the
structure and dynamics of food webs, and numerous analytical approaches are now …

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 …

Specialization is a concept based on a broad theoretical framework developed by
evolutionary biologists and ecologists. In the past 10 years, numerous studies have reported …

Ecological opportunity–through entry into a new environment, the origin of a key innovation
or extinction of antagonists–is widely thought to link ecological population dynamics to …

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 …

Patterns of resource use observed at the species level emerge from the way individuals
exploit the range of available resources. Hence, accounting for interindividual differences in …

Gene flow among populations is typically thought to be antagonistic to population
differentiation and local adaptation. However, this assumes that dispersing individuals …

Venoms are integrated phenotypes that evolved independently in, and are used for
predatory and defensive purposes by, a wide phylogenetic range of organisms. The same …
