(William Edward) 64063098 A Review of the Middle American Tree Frogs of the Genus Ptychohyla Produced by Chris Curnow, Tom Cosmas, Joseph Cooper and the Online Distributed Proofreading Team at https://www.pgdp.net "A Review of the Middle American Tree Frogs of the Genus Ptychohyla" by William E. Duellman is a scientific publication written in the early 1960s. The work focuses extensively on the anatomy, morphology, and ecological characteristics of the Ptychohyla frogs found in the cloud forests of Middle America. It likely serves as a vital resource for researchers and enthusiasts interested in the taxonomy and biology of these specific hylid frogs. The opening of the publication lays the groundwork for a detailed analysis of the Ptychohyla genus, highlighting the obscure status of many species due to limited previous research. Duellman discusses his own efforts in collecting specimens, recording breeding calls, and the challenges faced in studying these frogs in their natural mountainous habitats. He provides insight into the methodology of his research and the background of prior studies, indicating the need for a comprehensive overview of the species known up to that time, as well as the various life history aspects that remain under-explored.
