Biotic Acceptance In Introduced Amphibians And Reptiles In Europe And North America, Karen H. Beard

Karen H. Beard

Aim: The biotic resistance hypothesis argues that complex plant and animal communities are more resistant to invasion than simpler communities. Conversely, the biotic acceptance hypothesis states that non-native and native species richness are positively related. Most tests of these hypotheses at continental scales, typically conducted on plants, have found support for biotic acceptance. We tested these hypotheses on both amphibians and reptiles across Europe and North America. Location: Continental countries in Europe and states/provinces in North America. Methods: We used multiple linear regression models to determine which factors predicted successful establishment of amphibians and reptiles in Europe and North America, …
