    • We describe a new species of Hyalinobatrachium from the Amazonian   slopes of the Andes in Peru and Bolivia on the basis of morphological,   bioacoustic and genetic characteristics. Hyalinobatrachium carlesvilai   sp. nov. can be distinguished from other species of Hyalinobatrachium   by the combination of the following characters: (1) truncate snout in   dorsal and lateral view; (2) white pericardium; (3) enameled dorsal,   tarsal and cloacal folds; (4) hand webbing formula III 2(-) -1(+) IV;   (5) iris cream; (6) advertisement call consisting of a single,   frequency-modulated note with a pulsed section followed by a tonal   section. The new species had been previously identified as   Hyalinobatrachium munozorum and H. bergeri. The advertisement call of   the new species was previously assigned to H. bergeri. Here we describe   the previously unknown call of Hyalinobatrachium bergeri. Additionally,   we study the taxonomic status of H. lemur and H. pellucidum and place   the former as synonym of the later. We extend the distribution of H. pellucidum to Departamento Cusco in southern Peru.

  • Priority areas for amphibian conservation in a neotropical megadiverse country : the need for alternative, non place based, conservation
  • 2011
  • In: Biodiversity and Conservation. - : Springer Science and Business Media LLC. - 0960-3115 .- 1572-9710. ; 20:7, s. 1557-1570
  • Journal article (peer-reviewed)abstract
    • Amphibians constitute one of the most threatened species group worldwide. Because they are affected by various threats such as habitat destruction, chytrid fungus, climate change, invasive species and human use, different approaches are needed for their conservation. In this paper we examine patterns of alpha diversity, endemism and threatened species distributions of amphibians in Bolivia. We modeled distribution data using ecological niche modeling implemented with MaxEnt (Maximum Entropy Modeling). In contrast with previous studies, we validated each individual map with specialists. Important areas for amphibian conservation were defined by overlapping species richness, endemism richness and concentration of threatened species, and then excluding all unsuitable habitats. Our goal was to identify high-priority sites for the conservation of amphibians in Bolivia. We discuss a place-based strategy (identification of priority areas) and the need for further non place-based strategies. We highlight the importance of strengthening two existing protected areas that together host up to 40% of Bolivia's threatened amphibian species, and we propose alternative strategies such as ex situ conservation for those species not covered by the priority areas. Bolivia's General Directorate for Biodiversity and Protected Areas (in Spanish, Direccin General de Biodiversidad y Areas Protegidas (DGBAP)) and Bolivian experts are jointly using the here presented results to define a national strategy of amphibian conservation for safeguarding this important element of Bolivia's biodiversity.
