The causes of biodiversity change are of great scientific interest and central to policy efforts
aimed at meeting biodiversity targets. Changes in species diversity and high rates of …

The metacommunity concept is an important way to think about linkages between different
spatial scales in ecology. Here we review current understanding about this concept. We first …

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

In a review of landscape-scale empirical studies, Fahrig (2017a) found that ecological
responses to habitat fragmentation per se (fragmentation independent of habitat amount) …

Habitat loss is a primary threat to biodiversity across the planet, yet contentious debate has
ensued on the importance of habitat fragmentation 'per se'(ie, altered spatial configuration of …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

We conducted an analysis of global forest cover to reveal that 70% of remaining forest is
within 1 km of the forest's edge, subject to the degrading effects of fragmentation. A synthesis …

There is increasing interest in the plant microbiome as it relates to both plant health and
agricultural sustainability. One key unanswered question is whether we can select for a plant …

Humans are altering the composition of biological communities through a variety of activities
that increase rates of species invasions and species extinctions, at all scales, from local to …

No species occurs everywhere. Indeed, the majority are absent from most places, and where
they do occur they are usually quite rare. Gaston discusses the structure of these …
