Book Description
The first major synthesis of marsupial frogs, this book is the magnum opus of renowned herpetologist William E. Duellman. This scientific masterpiece reveals many aspects of the lives of marsupial frogs and closely allied genera. Native to Central and South America, these amphibians differ from other frogs in that they protect their eggs after oviposition by either adhering them to the female’s back or placing them in a specialized dorsal pouch (thus the common name, marsupial frog). During mating, the male typically collects the eggs from the female with his feet—often one at a time and always out of water—fertilizes them, and then tucks them into the female’s pouch or attaches them to her back. In some species these eggs hatch as tadpoles, but most emerge as miniatures of the adults. Even among the tadpoles there is remarkable divergence, with some behaving in the typical manner (feeding and metamorphosing), whereas others forego all feeding until they metamorphose. In Marsupial Frogs, William E. Duellman’s synthesis of all that is known about the unique family Hemiphractidae is largely based on decades of his own careful laboratory and field study. He reveals the diversity of exotic color patterns and the frogs' geographic distributions by providing more than 200 photographs, illustrations, and maps. This exceptional tome should find its way into the libraries of serious herpetologists, tropical biologists, and developmental biologists. Included in this book are • A molecular phylogeny of the family Hemiphractidae • A thorough osteological analysis • A review of external morphological features • An overview of the evolution of reproductive modes • A biogeographic synthesis • Keys to genera and species • Diagnosis and thorough description of each species of marsupial frog • Colored physiographic maps depicting species distributions

Book Description
In a Panamanian pond, male túngara frogs (Physalaemus pustulosus) gather in choruses, giving their "advertisement" call to the females that move among them. If a female chooses to make physical contact with a male, he will clasp her and eventually fertilize her eggs. But in vying for the females, the males whose calls are most attractive may also attract the interest of another creature: the fringe-lipped bat, a frog eater. In the Túngara Frog, the most detailed and informative single study available of frogs and their reproductive behavior, Michael J. Ryan demonstrates the interplay of sexual and natural selection. Using techniques from ethology, behavioral ecology, sensory physiology, physiological ecology, and theoretical population genetics in his research, Ryan shows that large males with low-frequency calls mate most successfully. He examines in detail a number of explanations for the females' preferences, and he considers possible evolutionary forces leading to the males' success. Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators. Ryan considers in detail how predators, especially the frige-lipped bat (Trachops cirrhosus), affect the evolution of the túngara frog's calls.
