Aim Explanations of biogeographic diversity patterns have emphasized the role of large‐
scale processes that determine species pools, whereas explanations of local patterns have …

Exploring the mechanisms underlying community species richness is a key issue in ecology
and conservation biology, and many hypotheses based on small-scale, local processes …

Co‐existence theories fail to adequately explain observed community patterns (diversity and
composition) because they mainly address local extinctions. For a more complete …

Numerous studies have reported a significant pattern of decreasing plant species richness
across regional habitat gradients of increasing productivity or community biomass (Grace …

The present study proposes to reconcile the different spatial and temporal scales of regional
species production and local constraint on species richness. Although interactions between …

Evidence has been accumulating that species pools play a major role in regulating
variations in small-scale diversity. However, our ability to unambiguously estimate and …

We analysed a 50‐year dataset of avian species observations to determine how richness
and community composition varied over a period of landscape‐scale environmental change …

Context Understanding how landscape patterns affect species diversity is of great
importance in the fields of biogeography, landscape ecology and conservation planning, but …

Aim To determine the empirical relationships between species richness and spatial turnover
in species composition across spatial scales. These have remained little explored despite …

Two conflicting hypotheses have been proposed to explain large‐scale species diversity
patterns and dynamics. The unbounded hypothesis proposes that regional diversity …
