During his thirty years of research in herpetology he described seventeen new species or subspecies, most of them amphibians, such as a few Neotropical toads of the genus Atelopus.
From his studies on the Amazonian avifauna, he authored several papers on Neotropical ornithology and devised his Amazonian refugia theory to explain the rapid diversification of the Neotropical fauna in Pleistocene times.
