Abstract:

There is increasing awareness that human activities are altering the ways that natural systems operate and that local shifts in species composition and abundance can lead to abrupt and irreversible global change. Therefore, understanding the processes that buffer biological communities from critical shifts and how our actions affect natural stabilizing...

Biological invasions have been identified as one of the prominent drivers of global environmental change. In particular, invasive predators typically have substantial negative effects on populations of native prey, even driving species to extinction in extreme cases. However, beyond direct predatory effects, little is understood regarding the specific mechanisms by...

Effects of the invasive Pacific red lionfish Pterois volitans on native Atlantic coral-reef fish communities

Creator:

Albins, Mark A.

These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...
