Amphibians that live in tropical regions display notable ecological and taxonomic diversity. Although many studies have characterized patterns of species diversity along elevational gradients, the relationship between elevation and phenotypic diversity, such as changes in body size and shape, remains unclear.
The goal of this study was to examine the patterns between ecological and morphological divergence in terrestrial-breeding frogs, a diverse group of Neotropical amphibians. We conducted a literature review focusing on published taxonomy and systematic studies and collected morphological and ecological data of over 350 species representing seven genera in the family Strabomantidae.
We created a database to test the relationship between body size and elevation. Most data were collected from taxonomic and systematic studies, and analyses were performed in R (implemented in R Studio). We found that body size of the terrestrial frogs tends to increase with increasing elevation. However, not all taxa followed the same trends and additional data needs to be collected to test predictions regarding the emergence of similar eco-morphology across regions.
