Book Description
"Dendrobates andinus, new species, is a small arboreal frog from wet montane forest (1700-2020 m elev.) on the Pacific versant of the Andes in extreme southwestern Colombia. Although its color pattern - yellowish dorsolateral stripes on a black or dark brown body - is reminiscent of two other Colombian species (D. truncatus and Phyllobates aurotaenia), D. andinus is not closely related to them. Dendrobates andinus is tentatively placed in the pictus species group, in which its closest relative seems to be D. erythromos Vigle and Miyata, from lowland rain forest on the Pacific side of Ecuador. The recently described 'Phyllobates' azureiventris Kneller and Henle, from Amazonian Peru, incidentally, is also transferred to the pictus group of Dendrobates. Natural history data for Dendrobates andinus include observations on courtship behavior and cephalic amplexus; individuals are most frequently associated with water-filled bromeliads, where clutches of three or four eggs are laid. Sound spectrograms and waveforms of the advertisement call of Dendrobates erythromos are provided for future comparison when recordings become available for D. andinus, whose call was perceived in the field as a series of well-spaced 'crreek' notes. The call of erythromos is termed a retarded chirp call and is briefly compared with the characteristic chirp call of the histronicus species of Dendrobates"--Page 1

Book Description
Excerpt from A New Species of Poison Frog (Dendrobates) From Andean Ecuador: Including an Analysis of Its Skin Toxins Natural History), is a large free-living larva mm head-body length, 20 mm total length, seemingly past stage 25 (because of size, but limb buds not detectable on damaged body [died before preservation] Eyes and nostrils dorsolateral; spiracle sinistral and low; tail fins (damaged) narrow. Mouth (badly damaged) di rected anteroventrally; beak massive, with serrated cutting edges, and median indentation on lower edge; tooth rows 2/ 3, about equal in length, with second upper row widely broken medially and first lower row narrowly broken medially; oral disc indented laterally lower edge of oral disc with broad median gap in a single row of small papillae (upper edge not papillate).

Book Description
Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

Book Description
This is the first book to cover all the poison frogs in detail. All 65 species of Dendrobates, Epipedobates, Minyobates, and Phyllobates are discussed, with extensive coverage of the dozen species that are best known to naturalists and hobbyists alike.
