We review empirical studies on how bioinvasions alter food webs and how a food-web
perspective may change their prediction and management. Predation is found to underlie …

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 …

Why do species live where they live? What determines the abundance and diversity of
species in a given area? What role do species play in the functioning of entire ecosystems …

Invasion ecology has been criticised for its lack of general principles. To explore this
criticism, we conducted a meta-analysis that examined characteristics of invasiveness (ie the …

We review and synthesize recent developments in the study of the invasion of communities
in heterogeneous environments, considering both the invasibility of the community and …

Several recent, high-impact ecological studies feature natural microcosms as tools for
testing effects of fragmentation, metacommunity theory or links between biodiversity and …

After more than a century of being regarded as botanical oddities, carnivorous plants have
emerged as model systems that are appropriate for addressing a wide array of ecological …

Invasion by nonnative brook trout (Salvelinus fontinalis) often results in replacement of
cutthroat trout (Oncorhynchus clarki) in the inland western United States, but the underlying …

Dispersal among local communities can have a variety of effects on species composition
and diversity at local and regional scales. Local conditions (eg, resource and predator …

Little is known about the traits and mechanisms that determine whether or not a species will
be invasive. Invasive species are those that establish and spread after being introduced to a …
