The Ecology of Individuals: Incidence and Implications of Individual Specialization
Most empirical and theoretical studies of resource use and population dynamics treat conspecific individuals as ecologically equivalent. This simplification is only justified if interindividual nicheExpand

SCARED TO DEATH? THE EFFECTS OF INTIMIDATION AND CONSUMPTION IN PREDATOR–PREY INTERACTIONS
Predation is a central feature of ecological communities. Most theoretical and empirical studies of predation focus on the consequences of predators consuming their prey. Predators reduce preyExpand

MEASURING INDIVIDUAL-LEVEL RESOURCE SPECIALIZATION
Many apparently generalized species are in fact composed of individual specialists that use a small subset of the population's resource distribution. Niche variation is usually established by testingExpand

Why intraspecific trait variation matters in community ecology.
Natural populations consist of phenotypically diverse individuals that exhibit variation in their demographic parameters and intra- and inter-specific interactions. Recent experimental work indicatesExpand

The ecological causes of individual specialisation.
Many generalist populations are composed of specialised individuals, whose niches are small subsets of the population niche. This 'individual specialisation' is a widespread phenomenon in naturalExpand

Predator-prey naïveté, antipredator behavior, and the ecology of predator invasions
We present a framework for explaining variation in predator invasion success and predator impacts on native prey that integrates information about predator–prey naivete, predator and prey behavioralExpand

Sympatric Speciation: Models and Empirical Evidence
Sympatric speciation, the evolution of reproductive isolation without geographic barriers, remains highly contentious. As a result of new empirical examples and theory, it is now generally acceptedExpand

Assortative Mating in Animals
Assortative mating occurs when there is a correlation (positive or negative) between male and female phenotypes or genotypes across mated pairs. To determine the typical strength and direction ofExpand

Ecological release from interspecific competition leads to decoupled changes in population and individual niche width
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 when a speciesExpand

Intraspecific competition drives increased resource use diversity within a natural population
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 resources,Expand
