Over the last two decades, numerous studies have shown that alien predators contributed to
amphibian population declines. Both experimental studies and correlative field surveys …

A major challenge of invasion biology lies in the development of a predictive understanding
of invasion processes. Attempts to identify the proximate causes of invasion success or to …

The recognition that invasive alien species (IAS) are among the greatest threats to
biodiversity has stimulated a growing interest in their impacts on native amphibians. Here …

Nonnative crayfish have been widely introduced and are a major threat to freshwater
biodiversity and ecosystem functioning. Despite documentation of the ecological effects of …

North America harbors about 390 native species of crayfishes, 75% of the world's total. In
this article, we highlight the threats posed by nonindigenous crayfishes to freshwater …

In Alien Species and Evolution, biologist George W. Cox reviews and synthesizes emerging
information on the evolutionary changes that occur in plants, animals, and microbial …

Dispersal is a central process in ecology and evolution. It strongly influences the dynamics
of spatially structured populations and affects evolutionary processes by shaping patterns of …

212 The nuts and bolts of invasion ecology tions were generally made with the assumption
that the new species filled a 'vacant niche'and thus would integrate into their communities …

Alien species have been transported and traded by humans for many centuries. However,
with the era of globalization, biological invasions have reached notable magnitudes …

We examined the direct and indirect effects of two introduced species, the bullfrog (Rana
