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

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

Plant Genotypic Diversity Predicts Community Structure and Governs an Ecosystem Process
Theory predicts, and recent empirical studies have shown, that the diversity of plant species determines the diversity of associated herbivores and mediates ecosystem processes, such as abovegroundExpand

Homoploid Hybrid Speciation in an Extreme Habitat
According to theory, homoploid hybrid speciation, which is hybrid speciation without a change in chromosome number, is facilitated by adaptation to a novel or extreme habitat. Using molecular andExpand

GENOMIC REGIONS WITH A HISTORY OF DIVERGENT SELECTION AFFECT FITNESS OF HYBRIDS BETWEEN TWO BUTTERFLY SPECIES
Speciation is the process by which reproductively isolated lineages arise, and is one of the fundamental means by which the diversity of life increases. Whereas numerous studies have documented anExpand

Admixture and the organization of genetic diversity in a butterfly species complex revealed through common and rare genetic variants
Detailed information about the geographic distribution of genetic and genomic variation is necessary to better understand the organization and structure of biological diversity. In particular,Expand

What, if anything, is sympatric speciation?
Sympatric speciation has always fascinated evolutionary biologists, and for good reason; it pits diversifying selection directly against the tendency of sexual reproduction to homogenize populations.Expand

Compounded effects of climate change and habitat alteration shift patterns of butterfly diversity
Climate change and habitat destruction have been linked to global declines in vertebrate biodiversity, including mammals, amphibians, birds, and fishes. However, invertebrates make up the vastExpand

Can optimal defence theory be used to predict the distribution of plant chemical defences
Summary 1. The optimal defence theory (ODT) of chemical defence provides a predictive framework for the distribution of anti-herbivore defences in plants. One of its predictions is that chemicalExpand

Ehrlich and Raven proposed a model of coevolution where major host plant shifts of butterflies facilitate a burst of diversification driven by their arrival to a new adaptive zone. One prediction ofExpand
