The focus of Vences' work is on the amphibians and reptiles of Madagascar.
He works together with Frank Glaw on many taxonomic species descriptions; together they have described over 200 new species of frogs, and numerous new species of snakes, chameleons, and other reptiles.
In 1992, they produced a field guide to the reptiles and amphibians of Madagascar.
In 1994 they produced a second edition of this guide, including the descriptions of numerous new taxa, and a significantly expanded reptile section.
In 2007, a third edition was produced, which did not describe any new species, but included colour photographs and short text descriptions of over 100 unnamed species.

In recent years, Vences has been coauthor on several publications over a wide range of subjects, including but not limited to biogeography, amphibian disease and amphibian-associated microbiomes, population genetics, evolution and speciation, and taxonomy.
