The island of Madagascar hosts a large number of frogs with at least 315 described species, and many others still to be named. Northern Madagascar is rich in species, due to the heterogeneity of landscapes, including a large number of habitat types and ecosystems. These species are threatened by many factors, including environmental degradation and capture for wildlife trade. The amphibian species that live in the northern part of Madagascar are presented in this book, including aspects of their identification, ecology, natural history, and vocalizations. Illustrated in color throughout, this French-language guide is intended for researchers engaged in fieldwork and conservation projects, as well as tourists visiting the island.
