(William Edward) 60064140 A Distributional Study of the Amphibians of the Isthmus of Tehuantepec, México Produced by Chris Curnow, Joseph Cooper, Diane Monico, and the Online Distributed Proofreading Team at http://www.pgdp.net "A Distributional Study of the Amphibians of the Isthmus of Tehuantepec, México" by William E. Duellman is a scientific publication written in the mid-20th century. The work focuses on the amphibian fauna inhabiting the Isthmus of Tehuantepec, a critical zoogeographic region in Mexico. Duellman's study aims to catalog the species present in this area while also exploring the environmental conditions that contribute to their distribution. The opening of the study introduces the importance of the Isthmus of Tehuantepec in the context of Middle American zoogeography. The author outlines the historical context of prior amphibian studies in the region, notes the lack of a comprehensive herpetological record, and posits the significance of the region in understanding amphibian dispersal patterns. Duellman shares insights from his fieldwork, which commenced in the 1950s and includes substantial ecological data collected during various seasons, highlighting the challenges and findings encountered in studying the diverse environments inhabited by amphibians in this unique area.
