Aquatic Nuisance Species: A multi-stage approach to understanding the invasion ecology of exotic crayfish in Northern and Southern California

摘要: Author(s): Kats, Lee; Pintor, Lauren; Sih, Andrew; Kerby, Jake | Abstract: Biological invasions are widely thought to have major negative impacts on native communities and ecosystems (Vitousek et al. 1996; Parker 1999; Mack 2000). Exotic species the second most important cause of extinctions (after habitat destruction) in United States (Enserink 1999) an losses biodiversity worldwide (Sala From economic, resource management view, exotic can direct indirect commercially-important natural resources – e.g., fisheries, crops (Pimentel Although impact via various mechanisms (e.g., competition, spread disease, hybridization), for aquatic animals, a key mechanism is clearly predation (Moyle Light Gamradt Kats Knapp 2001). Thus goal interface between basic applied ecology understand potentially damaging invasive predators (including omnivores), order minimize their impacts.
