A regional species pool comprises all species available to colonize a focal site. The roots of
the concept are imbedded in island biogeography theory, supply-side ecology, and early …

▪ Abstract Oak gall wasps (Hymenoptera: Cynipidae, Cynipini) are characterized by
possession of complex cyclically parthenogenetic life cycles and the ability to induce a wide …

Metacommunity ecology links smaller-scale processes that have been the provenance of
population and community ecology—such as birth-death processes, species interactions …

A plethora of different theories, models, and concepts make up the field of community
ecology. Amid this vast body of work, is it possible to build one general theory of ecological …

The species richness (diversity) of local plant and animal assemblages—biological
communities—balances regional processes of species formation and geographic dispersal …

Many hypotheses have been proposed to explain the great variation among regions in
species richness. These were tested by first examining patterns of species richness of birds …

The dictionary definition of a law is:" Generalized formulation based on a series of events or
processes observed to recur regularly under certain conditions; a widely observable …

The first photographs of the Earth to be taken from outer space are said to have had a
profound influence on how humanity perceives its place in the Universe. They provided a …

1. Are local ecological communities ever saturated with species? That is, do they ever reach
a point where species from the regional pool are unable to invade the local habitat because …

1. We measured beta diversity, or turnover in species composition, in each of 15 taxa
(including plants, vertebrates and invertebrates), along two common transects: NS and WE …
