Ecological niche modeling as a predictive tool: silverand bighead carps in North America

摘要: The silver carp and bighead (Cyprinidae), native to eastern Asia, have been introduced into the United States in attempts improve water quality aquaculture ponds, reservoirs, sewage pools. Escaped or released specimens from fish farms reported many states, both species are already locally established spreading further. We used Genetic Algorithm for Rule-set Prediction (GARP) model niches of these two carps their ranges using hydrologic general environmental parameters concert with distributional data. results accurately predicted occurrence data withheld modeling process (P < 0.01). then projected niche models onto North American landscape. Native range significantly known introductions 0.001). Further, suggest that potential throughout U.S. selected areas West Coast.
