This monograph presents a detailed review of the systematics of the species complex of Amazonian frogs Hypsiboas calcaratus – H. fasciatus. These frogs have a wide distribution in the Amazon basin and are a prominent component of scientific collections in the region. The review includes a phylogeny based on genetic evidence and also an integrative analysis of genetics, morphology and bioacoustics to determine species limits. The analysis indicates the existence of 11 candidate species, a five-fold in-crease relative to the current taxonomy. Four of the candidate species are described as new species and one is resurrected from a previous synonymy. The review is thoroughly illustrated with high-quality images. All multimedia elements (photographs and advertisement calls) are available at the FaunaWebEcuador web-site: http://zoologia.puce.edu.ec/Vertebrados/Vertebrata.aspx
This book analyzes different facets of anuran amphibian distribution in South America. We integrate alternative biological metrics employing cutting-edge methods to understand the dynamic processes underlying species distribution patterns. By using the modern biogeographic toolbox, we explore how richness gradients, phylogenetic diversity, functional diversity, and range size/endemism distribution of amphibians vary along the continent. Moreover, we present a robust proposal for priority areas for conservation of anurans in South America that maximizes representativeness of distinct biodiversity facets.
El departamento del Guaviare es una zona de confluencia de elementos de la Amazonía, Orinoquía y escudo guayanés, condición que se refleja en la diversidad de anfibios y reptiles. Esta obra, que incluye algunas de las especies de este grupo faunístico registradas en el municipio de San José del Guaviare, nace del interés de la Universidad Nacional de Colombia y de la financiación de la "Dirección Nacional de Extensión, Innovación y Propiedad Intelectual", por apoyar proyectos sociales de turismo naturaleza en la región.

Reptiles and Amphibians of Australia is a complete guide to Australia’s rich and varied herpetofauna, including frogs, crocodiles, turtles, tortoises, lizards and snakes. For each of the 1218 species there is a description of its appearance, distribution and habits. These descriptions are also accompanied by distribution maps and, in many cases, one of the book's more than 1000 colour photographs of living animals. The book also includes 130 simple-to-use dichotomous keys, accompanied by hundreds of explanatory drawings, that in most cases allow a specimen in hand to be identified. In addition, it has a comprehensive list of scientific references for those wishing to conduct more in-depth research, an extensive glossary, and basic guides to the collection, preservation and captive care of specimens. This classic work was originally published in 1975. The updated seventh edition contains a new Appendix that discusses recent changes and lists over 80 new or resurrected species and genera that have been added to the Australian frog and reptile fauna since the 2014 edition.
