Mapping the potential distribution of the invasive Red Shiner, Cyprinella lutrensis (Teleostei: Cyprinidae) across waterways of the conterminous United States

摘要: Predicting the future spread of non-native aquatic species continues to be a high priority for natural resource managers striving maintain biodiversity and ecosystem function. Modeling potential distributions alien through spatially explicit mapping is an increasingly important tool risk assessment prediction. Habitat modeling also facilitates identification key environmental variables influencing distributions. We modeled distribution aggressive invasive minnow, red shiner (Cyprinella lutrensis), in waterways conterminous United States using maximum entropy (Maxent). used inventory records from USGS Nonindigenous Aquatic Species Database, native C. lutrensis museum collections, geographic information system 20 raster climatic produce map habitat. Summer were most predictors distribution, which was consistent with temperature tolerance this species. Results study provide insights into locations conditions US that are susceptible invasion.
