Niche shift in four non‐native estrildid finches and implications for species distribution models

摘要: Non-native species can have severe impacts on ecosystems. Therefore, predictions of potentially suitable areas that are at risk the establishment non-native populations desirable. In recent years, distribution models (SDMs) been widely applied for this purpose. However, appropriate selection records, whether from native area alone or also introduced range, is still a matter debate. We combined analyses and realized climate niches to understand differences between based all locations, as well locations range only. Our approach was four estrildid finch many regions around world. results showed SDMs location data may underestimate potential given species. The climatic in their ranges differed those ranges. Niche comparisons resulted low overlap values, indicating considerable niche shifts, least these All high spread over tropical subtropical areas. transferring temperate has degree uncertainty, we urge caution when assessing higher latitudes.
