Broad-scale ecological correlates affecting species richness and abundance patterns of amphibians were studied in 37 sampling sites from 15 independent protected areas in the Albertine Rift, East Africa. Amphibians were caught by a combination of sampling techniques, including time-constrained visual searching, pitfalls with drift fences, dip-netting, and opportunistic observations. In total, 73 species of amphibians were recorded, some of them occurring only once in the samples and some more than 1,000 times. Once relative field effort at each study site was taken into account, multivariate regression analyses showed that amphibian species richness was positively influenced by percent canopy cover and altitude. On the other hand, population abundance was influenced by a combination of three different variables: positively by percent canopy cover and rainfall, and negatively by human activities. The …
