In “The Genera of Phyllomedusine Frogs (Anura: Hylidae)," William Edward Duellman presents an exhaustive examination of the taxonomy, ecology, and evolution of the phyllomedusine frogs, a unique group characterized by their arboreal lifestyles and striking coloration. Utilizing a systematic and scientific literary style, this work is meticulously organized, richly illustrated, and grounded in rigorous field research. Duellman synthesizes decades of research, contextualizing the frogs within the broader framework of amphibian diversity and conservation, thereby contributing significantly to herpetology and related fields. William Edward Duellman is a preeminent herpetologist whose extensive career spans over half a century, notably focusing on the amphibian biodiversity of Central and South America. His background in ecology and evolutionary biology, coupled with fieldwork in tropical habitats, provided him with an intimate understanding of the phyllomedusine frogs. Duellman'Äôs commitment to preserving amphibian habitats is evident in his advocacy for conservation, which permeates the pages of this comprehensive monograph. For students, researchers, and enthusiasts of amphibian biology, Duellman'Äôs work is an essential resource that not only deepens understanding of phyllomedusine frogs but also stimulates further inquiry into their conservation status. This book stands as a vital contribution to herpetological literature and promotes a greater appreciation for the intricate ecosystems these frogs inhabit.
