Aquatic invasive species harming U.S. ecosystems, fisheries

Global ecological impacts of invasive species in aquatic ecosystems.

The introduction of invasive species, which often differ functionally from the components of the recipient community, generates ecological impacts that propagate along the food web. This review aims to determine how consistent the impacts of aquatic invasions are across taxa and habitats. To that end, we present a global meta-analysis from 151 publications (733 cases), covering a wide range of ...

Invasive Species and Fire in California Ecosystems

nvasive plant species occur throughout all floristic regions of California, but their spatial extent, diversity, and impacts within these regions vary considerably. Alterations of natural disturbance regimes have made communities more susceptible to these invasions (Brooks et al. 2004). Fire is a natural and chronic disturbance in many California plant communities and has been observed to promo...

Non-native invasive species and novel ecosystems

Invasions by non-native species have caused many extinctions and greatly modified many ecosystems and are among the major anthropogenic global changes transforming the earth. Beginning in the mid-1980s, a dramatic burst of research in invasion biology has revealed a plethora of previously unrecognized impacts and laid bare the scope of the phenomenon. Similarly, research on various methods of m...

The need for a protean fisheries science to address the degradation of exploited aquatic ecosystems

In this introductory paper we highlight key questions that were discussed during the symposium on “Status, functioning and shifts in marine ecosystems” organized by the Association Française d’Halieutique (French Association for Fisheries Sciences, Montpellier, France, July 2015). This symposium illustrated that fisheries science is now working at multiple scales and on all dimensions of socio-...
