Summary

Conclusions: Frogs and toad species were more abundant and diverse where habitat patch diversity was high or where there were forested wetland edges. Relative abundances of amphibian populations correlated positively with metrics such as the length of edge between forest and wetland, and negatively with the presence of agricultural and urban land. Thresholds/Learnings: Synopsis: This study examined landscape-level relationships for frogs and toads by measuring associations between relative abundance and species richness based on survey data derived from anuran calls and features of land cover maps for Iowa and Wisconsin. Relative abundances correlated positively with metrics such as the length of edge between forest and wetland, and [...]
