AMPHIBIAN CONSERVATION IN THE CAATINGA BIOME AND SEMIARID REGION OF BRAZIL 1,3 2 MILENA CAMARDELLI AND MARCELO F.

In this study, we searched for ‘‘hot spots’’ of amphibians in these two regions and assessed whether the priority areas established by the MMA coincided with those suitable for amphibian conservation. We determined amphibian hot spots by means of three estimates: areas of endemism, areas of high species richness, and areas with species that are threatened, rare, or have very limited distributions. We then assessed the degree of coincidence between amphibian hot spots and the priority areas of the MMA based on the current conservation units. We analyzed areas of endemism with the use of a parsimony analysis of endemicity (PAE) on quadrats. The Caatinga biome and semiarid region showed four and six areas of endemism, respectively, mainly associated with mountainous areas that are covered by isolated forests and positively correlated with species richness. All areas of endemism coincided with one or more priority areas defined by the MMA. We identify 15 priority areas for amphibian conservation in the Caatinga biome and semiarid region, including the creation of new full-protection conservation units. RESUMO: A definic¸a˜odea´reas priorita´rias para a conservac¸a˜o da biodiversidade brasileira foi proposta pelo Ministe´rio do Meio Ambiente (MMA) em 2007, mas ate´ o presente momento na˜oha´ estudo meto´dico que defina a´reas priorita´rias para a conservac¸a˜o de anfı´bios no bioma Caatinga ou no Semia´rido brasileiro. Neste estudo, buscamos por ‘‘hot spots’’ de anfı´bios nestes dois polı´gonos e verificamos se as a´reas priorita´rias do MMA coincidem com a´reas adequadas para a conservac¸a˜o dos anfı´bios. Determinamos os hot spots de anfı´bios por meio de treˆs estimadores: a´reas de endemismo, a´reas de alta riqueza de espe´cies e a´reas com espe´cies ameac¸adas, raras e/ou com padro˜es de distribuic¸a˜o restrita. Em seguida, acessamos o grau de coincideˆncia entre hot spots de anfı´bios e a´reas priorita´rias do MMA, igualmente considerando as unidades de conservac¸a˜o correntemente instaladas. A detecc¸a˜odea´reas de endemismo foi realizada pela Ana´lise de Parcimoˆnia de Endemicidade (PAE), usando quadrados. O bioma Caatinga e o Semia´rido apresentaram, respectivamente, quatro e seis a´reas de endemismo, principalmente associadas a a´reas montanhosas cobertas por florestas isoladas, e estiveram positivamente correlacionadas a` riqueza de espe´cies. Todas as a´reas de endemismo coincidiram com uma ou mais a´reas priorita´rias definidas pelo MMA. No´s identificamos 15 a´reas priorita´rias para conservac¸a˜o de anfı´bios no bioma Caatinga e Semia´rido, ale´m da criac¸a˜o de novas unidades de conservac¸a˜o de protec¸a˜o integral no Brasil.

    Amphibia-Reptilia 31 (2010): 411-418 A new species of small Scinax Wagler, 1830 (Amphibia, Anura, Hylidae) of the Scinax ruber clade from Cerrado of central Brazil Manoela Woitovicz Cardoso, José P. Pombal Jr. Abstract. A new species of the Scinax ruber clade from the Brazilian Cerrado Domain similar to Scinax fuscomarginatus, S. parkeri, S. trilineatus and S. wandae is described. It is characterized by small snout-vent lenght, body slender, head approximately as long as wide and slightly wider than body, subovoid snout in dorsal view, protruding snout in lateral view, a developed supratympanic fold, absence of flash colour on the posterior surfaces of thighs, hidden portions of shanks and groin, and large vocal sac. Scinax lutzorum sp. nov. differs from S. fuscomarginatus, S. parkeri and S. trilineatus by its slightly larger SVL; from Scinax fuscomarginatus and S. parkeri it differs by its more slender body; from Scinax fuscomarginatus and S. trilineatus the new species differs by its wider head and more protruding eyes; and it differs from Scinax parkeri and S. wandae by its shorter snout.

  • Notes on the Paradox Frog, Pseudis Paradoxa, in Bolivia
    British Herpetological Society Bullton. No. 68. 1999 NOTES ON THE PARADOX FROG, PSEUDIS PARADOXA, IN BOLIVIA IGNACIO DE LA RIVA Department of Biodiversity and Evolutionary Biology Museo Nacional de Ciencias Naturales a Jose Gutierrez Abascal 2, 28006 Madrid, Spain INTRODUCTION The South American Paradox Frog, Pseudis paradoxa (Plate. 1) is primarily a dweller of open, lowland areas, where it inhabits marshes, ponds and other types of lentic water bodies. It has a discontinuous distribution from Colombia to Argentina. Inter- populational differences primarily in colour pattern, as well a in some other features, have led to the recognition of seven subspecies [P. p. bolbodactyla and P. p. fusca were recently proposed to be elevated to specific status (Caramaschi and Cruz, 1998)]. DISTRIBUTION AND SUBSPECIES IN BOLIVIA For taxonomic and biogeographical reasons, the lowlands of Bolivia are an interesting area with respect to this frog. The distribution of the species in this country is poorly known. The first Bolivian record of P. paradoxa was provided by Muller and Hellmich (1936) at San Fermiin, Department of Santa Cruz. Since then, it was reported at some other localities, mostly in the Department of Santa Cruz [see De la Riva (1990) and below]. It was interesting that it was also discovered at two localities in southeastern Peru (Duellman and Salas, 1991; Henle, 1992). These discoveries made plausible that it ranges throughout the intermediate area of extensive, suitable habitat of humid savannas in the Bolivian Department of Beni. However, there is a surprising scarcity of published records for this huge and relatively (by Bolivian standards) well surveyed zone.
