▪ Abstract The focus of most ideas on diversity maintenance is species
coexistence, which may be stable or unstable. Stable coexistence can be
quantified by the long-term rates at which community members recover from low
density. Quantification shows that coexistence mechanisms function in two major
ways: They may be (a) equalizing because they tend to minimize average fitness

▪ Abstract As better phylogenetic hypotheses become available for many groups
of organisms, studies in community ecology can be informed by knowledge of the
evolutionary relationships among coexisting species. We note three primary
approaches to integrating phylogenetic information into studies of community
organization: 1. examining the phylogenetic structure of community assemblages,
2. explori... hiện toàn bộ

▪ Abstract Contributions from the field of population biology hold promise for
understanding and managing invasiveness; invasive species also offer excellent
opportunities to study basic processes in population biology. Life history
studies and demographic models may be valuable for examining the introduction of
invasive species and identifying life history stages where management will be
