Abstract Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action 1,2 . Ongoing developments in taxonomy, threatening processes and research further underscore the need reassessment 3,4 Here we report findings second Global Amphibian Assessment, evaluating 8,011 International Union Conservation Nature Red List Threatened Species. We find that amphibians most threatened vertebrate class (40.7% globally threatened). The updated...
The definition of conservation targets is strategic for the protection biodiversity and must ensure representativeness persistence components. This especially critical in fast-disappearing ecosystems, such as Cerrado, where opportunities are rapidly diminishing. We evaluate how different categories protected areas (PAs) Cerrado contribute to achieve 17% target defined by Convention on Biological Diversity (CBD). Deforestation rates sustainable use PAs (IUCN IV VI) similar those outside PAs,...
Abstract The leaf or monkey frogs of the hylid subfamily Phyllomedusinae are a unique group charismatic anurans. We present molecular phylogenetic analysis that includes 45 60 species phyllomedusines using up to 12 genes and intervening tRNAs. aims were gain better understanding position Phrynomedusa , test monophyly explore relationships among several putative lineages ( Hylomantis H. buckleyi Group, Phasmahyla four groups Phyllomedusa remain unassigned any group), examine implications our...
Significance We report for island populations of the termite-eating common gecko species Gymnodactylus amarali rapid parallel morphological and ecological change in response to human-caused environmental disturbance. The islands were formerly part an extensive terrestrial ecosystem; 1997, area was flooded construct a reservoir, fragmenting higher portions into separate islands. Populations on all five studied have proportionally larger heads than at nearby mainland sites. new morphology is...
Members of the Leptodactylus mystaceus species complex are widely distributed in forests and open formations South America east Andes. Species morphologically similar or indistinguishable among each other, but acoustic data have been cornerstone for discrimination across their geographic ranges. In this paper, we re-examine monophyly, diversity, relationships L. on basis morphology, coloration, acoustics, DNA sequences. Morphological color patterns originally used to allocation also...
In this study, we assessed the impacts of land use and climate changes on river flows 81 watersheds within Cerrado biome, Brazil, based a comprehensive analysis field secondary data acquired between 1985 2018. Complementarily, projected future deforestation scenario up to 2050 predicted their surface water in study area. We observed that direct by large-scale oriented production irrigated agricultural commodities have more significantly impacted than changes. estimated an average decrease...
Bokermannohyla (tribe Cophomantini) is an endemic genus of Brazilian treefrogs containing 32 species arranged into four phenetic groups. The B. pseudopseudis group includes nine species, which are typically found in rupestrian ecosystems disjunct mountain ranges. Tadpoles have been shown to be important sources information for the taxonomy this genus, although careful analyses character variation and descriptions internal anatomy remain scarce. Since first description tadpoles was based on a...
Recent studies have argued that changes in fire regimes the 21st century are posing a major threat to global biodiversity. In this scenario, incorporating species’ physiological, ecological, and evolutionary traits with their local exposure might facilitate accurate identification of species most at risk from fire. Here, we developed framework for identifying animal vulnerable extinction fire-induced stress Brazilian savanna. The proposed addresses vulnerability two components: (1) exposure,...
Amphibian skin secretions are known as a rich source of biologically active molecules, most which alkaloids, biogenic amines, and peptides. Dermaseptins class antimicrobial peptides present in tree frogs the Phyllomedusa genus. They cationic molecules 28-34 residues that permeabilize membrane Gram-positive Gram-negative bacteria, yeasts, filamentous fungi, showing little or no hemolytic activity. This work reports isolation, molecular mass analysis, primary structure determination,...
O Estado de Mato Grosso do Sul situa-se na porção mediana da grande diagonal formações abertas América Sul, uma região que abriga diversidade anfíbios e répteis, sendo algumas endêmicas. Apesar sua importância biogeográfica, essa tem sido pouco considerada em estudos com abrangência regional. Dentre os componentes fitofisionômicos compõem cuja representatividade se faz presente no Estado, as matas estacionais deciduais são elementos marcantes Serra Bodoquena. Devido a peculiaridade desse...
Abstract The South American and West Indian Casque‐headed Treefrogs (Hylidae: Hylinae: Lophyohylini) include 85 species. These are notably diverse in morphology (e.g. disparate levels of cranial hyperossification) life history different reproductive modes, chemical defences), have a wide distribution, occupy habitats from the tropical rainforests to semiarid scrubland. In this paper, we present phylogenetic analysis hylid tribe based on sequence fragments up five mitochondrial ( 12S , 16S...
Scinax is the most species-rich genus of Neotropical treefrogs, with 129 currently recognized species divided between two major clades, S. catharinae and ruber clades. The clade includes 52 placed in perpusillus groups, whereas composed 77 species, 13 which are included groups: rostratus uruguayus all 64 remaining being unassigned to any group. Although some studies have addressed phylogenetic relationships genus, its remain poorly understood. To test monophyly within among them, we...
We present a list of squamate reptiles from Parque Nacional da Emas (PNE), ten neighbor private properties and Estadual Nascentes do Rio Taquari, states Goiás, Mato Grosso, Grosso Sul. The study area encompasses the headwaters Araguaia Taquari river basins part Paranaíba River Basin, resulting in significant habitat heterogeneity. Inside PNE, we recorded 74 species: 47 snakes, 21 lizards six amphisbaenians. If consider also neighboring areas, richness value raises to 87 54 27 From these, 52...
