The trophic amplitude for each age class and sex-season category was quantified using Shannon-Weaver Index, and the trophic niche overlap between ages and categories by using the Pianka Index.

Scinax aromothyella [Geographic distribution]. The present study thus provides empirical evidence supporting the hypothesis that turtles reaching 40–45 cm of curved carapace length arrive to Uruguayan waters following a coastal migratory route along the Brazilian coast and confirms the existence of seasonal movements between Uruguayan and South-Brazilian waters and a high fidelity for feeding grounds in the Southwestern Atlantic Ocean. Global Amphibian Assessment. [ Links ], PECHMANN, J. H. & WILBUR, H. M. 1994. Each of these working groups proposed initiatives to complete the categorization of both taxonomic groups at a regional (national) level using the IUCN criteria. Free metacercariae of an undetermined species of digenetic (Diplostomidae) were found over in the kidneys of anurans of the species Rhinella fernandezae collected in the in the municipality of Imbé, on the northern coast of Rio Grande do Sul, in southern Brazil. In areas of accelerated urban development, we find Argenteohyla siemersi (Mertens, 1937), Ceratophrys ornata (Bell, 1843), Melanophryniscus montevidensis, Physalaemus fernandezae (Müller, 1926), and Pleurodema bibroni Tschudi, 1838. Our results consist of initial knowledge base on the anurofauna of APA do Ibirapuitã, supporting recommendations for future conservation actions to APA and also for the grassland biomes, which are increasingly threatened by human activities. Sea turtles comprise a particular case because they do not reproduce in Uruguayan beaches, although the Uruguayan maritime space is an important feeding area for the sea turtle populations of the southern Atlantic (LÓPEZ-MENDILAHARSU et al., 2006). First record of Chaunus achavali (Anura, Bufonidae) from Rio Grande do Sul, Brazil, with a key for the identification of the species in the Chaunus marinus group. 1837, - With the participation of the IUCN Uruguayan Committee, two biodiversity groups were created to bring together the researchers working locally on each zoological group: Amphibia and Reptilia.

This study analyzed the pattern of movements of a population of Melanophryniscus montevidensis among five sites selected in Barra de la Laguna de Rocha, Uruguay. Finally, taking in mind the information stated above, we are allowed to recommend that the "in situ" conservation strategies seem to be the most appropriate for the Uruguayan herpetofauna. - Foto, - Liophis anomalus Ophiodes intermedius Boulenger, 1894 We analyzed the reproductive traits of a population of Melanophryniscus montevidensis.

(Cope, 1868) (Wagler, 1824) - Foto, - The diet of Leptodactylus ocellatus (L., 1758) was studied in specimens collected at Maldonado Department (Uruguay), where monthly surveys were made between August 1998 and March 2000. A. Several individuals revealed high site-fidelity for breeding. - Foto, - We detected a negative correlation between the presence of debris and turtle's Such information is essential to estimate the effects of habitat fragmentation in wild populations, as individuals would not be able to change their habitats easily. - Foto, - Leptophis ahaetulla marginatus (Cope, The Herpetological Journal 16:213-220. Estes, Queiroz & Gauthier, 1988, - Cnemidophorus lacertoides - Foto, - Echinanthera poecilopogon Stenocercus Duméril & Bibron, This study aimed to determine anuran species richness, abundance, constancy of occurrence, and reproductive modes, and to compare the taxonomic composition in the APA with other localities within the grassland areas of the southernmost of South America. 30.500, El Pinar, Canelones, 15008, Uruguay VIIIUniversidad de la República, and Universidad Católica del Uruguay. Consequently, most species have been assigned to the large,polyphyletic, and poorly defined genera Ameiva and Cnemidophorus. The reproductive events were associated to rainfalls. [ Links ], LIPS, K.

It is important to consider that several species of reptiles and amphibians have been recently recorded for Uruguay, and because of that, updated information on the distribution and natural history of these species is scarce and fragmented. A. Species occurring in rice-crops zones are: Leptodactylus chaquensis, L. podicipinus, Lysapsus limellus, and Chthonerpeton indistinctum (Reinhardt & Lütken, 1862). Raúl Maneyro also acknowledges a doctoral fellowship from Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) at the Pontifícia Universidade Católica do Rio Grande do Sul, Brasil. Melanophryniscus montevidensis probably inhabited patchy sand dune environments in Buenos Aires. distribution of the vegetation) in this habitat. 1857) Montevideo, DI.R.A.C. We studied specimens of P. patagoniensis deposited in several herpetological collections from Brazil. - Foto, - Liophis almadensis Por el contrario, está presente en toda Bélgica y Francia, con la excepción de los departamentos alpinos y la Riviera francesa en el sureste del país, ... En Portugal, la especie queda relegada al extremo noroeste, desde la Serra do Gêres hasta la desembocadura del río Miño, descendiendo a lo largo de la costa hasta Aveiro. In the case of amphibians and the majority of reptile species, excluding sea turtles, we consider that all species have breeding populations and that Uruguayan populations may experience a negligible "rescue effect" from populations outside the country (BROWN & KODRIC-BROWN, 1977; HANSKI & GYLLENBERG, 1993). height and phytophysiognomies). A total of 96 dead stranded turtles were analyzed and 70% presented debris in and 76 juveniles). - Foto, - Echinanthera occipitalis Important, but previously undescribed, character suites include pupilshape; the frontal ridge; longitudinal division of the interparietal; the rostral groove; patterns of supraciliary fusion; thepreauricular skin fold; the “toothy” first supralabial; modified apical granules; the pectoral sulcus; expansion of scales atthe heel; tibiotarsal shields; scales between the digital lamellae along the postaxial edges of the toes; scale surfacemicrostructure of macrohoneycomb, macroridges, or lamellae; distribution patterns and morphology of lenticular scaleorgans; types of epidermal generation glands; and several hemipenial structures. Among the recaptured individuals, 18.9% moved among sites. Phrynops williamsi Rhodin & To this end, carapace scute biopsies were collected from 20 turtles foraging on coastal rocky outcrops in East Uruguay and sliced in successive 30-μm layers using a cryostat.

Our report provides for the first time direct observation of death and injuries as a consequence of falls from dams and walls of hydroelectric plants shortly after the reservoir formation, apparently as an attempt to abandon the artificial lakes; it also corroborates the species’ dependence on lotic environments, justifying the increasing concern with its conservation in southern Brazil. [ Links ], SCHARGEL, W. E.; RIVAS FUENMAYOR, G. & MYERS, C. W. 2005. Out of 47 amphibian species, seven are listed as Critically Endangered (CR), five as Endangered (EN), one as Vulnerable (VU), three as Near Threatened (NT), and two as Data Deficient (DD); the remaining species are considered to be Least Concern (LC). Categorización de los anfibios del Uruguay. As a step towards assimilating knowledge, ecological niche models may identify likely suitable habitats for species, but lack the ability to enumerate species densities. - Foto, - Thamnodynastes strigatus Baur, 1893, - In particular, IUCN Red List categories are useful to define priority areas for conservation, and for that reason, the existence of Data Deficient taxa raises questions that are difficult to answer in order to provide timely and informed actions towards biodiversity protection.

Science 306:1783-1786. Five reproductive modes were recorded, and the most common mode consists of development of exotrophic tadpole and deposition in to lentic bodies of water (57.5%). Active searches were conducted in every site, and individuals were captured, sexed, measured, weighed, photographed, and released. 2006 IUCN Red List of Threatened Species. The majority of debris found were plastic, being hard plastics the most abundant in weight and The information used as a basis to assess each species was taken from published sources (ACHAVAL, 2001; CARREIRA et al., 2005; NÚÑEZ et al., 2004) as well as from personal observations of authors. 2005 and 2013.

This is a consequence of the newly acquired, highly detailed information on the distribution and natural history of these species provided by specialists working at the national level (KOLENC et al., 2003; KWET et al., 2005; MANEYRO & CARREIRA, 2006), which was not available to the authors of the GAA at the time of the first comprehensive assessment (KOLENC et al., 2003; KWET et al., 2005; MANEYRO & CARREIRA, 2006).
