Abstract Aim The knowledge of biodiversity facets such as species composition, distribution and ecological niche is fundamental for the construction biogeographic hypotheses conservation strategies. However, on these affected by major shortfalls, which are even more pronounced in tropics. This study aims to evaluate effect sampling bias variation collection effort Linnean, Wallacean Hutchinsonian shortfalls diversity measures richness, endemism beta‐diversity. Location Brazil. Methods We...
Abstract Although Brazil is a megadiverse country and thus conservation priority, no study has yet quantified gaps in the Brazilian protected areas (PAs) using extensive empirical data. Here, we evaluate degree of biodiversity protection knowledge within all PAs through gap analysis vertebrate, arthropod angiosperm occurrences phylogenetic Our results show that on most remain scant as 71% have less than 0.01 species records per km 2 . Almost 55% about 40% evolutionary lineages are not found...
The Neotropical genus Pseudopaludicola includes 21 species, which occur throughout South America. Recent studies suggested that the population of Andaraí, in state Bahia, is an undescribed related to P. pocoto. Herein we formally describe this new species from lowlands eastern Brazil. Recognition supported by adult morphology, advertisement call, karyotype, and molecular data. It diagnosed mainly its small size, terminal phalanges knobbed (lack any expansion digital tips), proportionally...
The Odontophrynus americanus species group is a complex of diploid and tetraploid hardly distinguished by morphological characters. It currently consists three allopatric (i.e. O. cordobae, lavillai, maisuma) one widely distributed americanus). We herein describe new from campo rupestre, typical phytophysiognomy the Espinhaço Range, Brazil. distinguishable complement 2n = 2x 22 chromosomes, small to medium-sized dorsal dark brown blotches with low contrast on light background, mid-dorsal...
The lizard genus Psilophthalmus was originally described from the sandy deposits at northern end of Serra do Espinhaço, in Santo Inácio, state Bahia, but since then it has been recorded other Brazilian localities states Minas Gerais, and Sergipe. Here, we review collected specimens based on molecular markers (mitochondrial 12S, 16S, ND4 cyt b, nuclear C-mos NT3) morphological evidence (external, hemipenial osteological morphologies). In course our revision find out that Rodrigues 1991...
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...
We describe a new species of Physalaemus assigned to the signifer Clade, and it is morphologically similar P. rupestris, from highlands Serra do Cipó in southern Espinhaço Range, State Minas Gerais, Southeastern Brazil. The diagnosed by using following combination character states: presence an arrow-shaped blotch on dorsum body; median longitudinal light stripe over urostyle region; belly ventral surface thigh marbled with dark gray irregularly shaped blotches bluish background; absence...
In an elevational gradient, the mountain top generally presents a reduced species diversity. However, it is there where we often find microendemic and quite still undescribed species. That prediction very common in underexplored Neotropical mountains, like those of Caparaó National Park – protected area that includes highest peak Atlantic Forest, megadiverse domain. Up its top, found dwarf frog genus Physalaemus (Anura, Leptodactylidae, Leiuperinae), belonging to P. signifer clade. After...
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,...
Mining causes profound impacts on biodiversity. In Brazil, mining pressure is intense, especially in highly biodiverse regions such as the Espinhaço range. We analyzed direct and indirect effects of potential geographic range 32 anuran eight bird species endemic to eastern Brazil mountaintops. also assessed local biodiversity rate both groups. Currently, 36.44% 28.80% median distribution species, respectively, are affected directly or indirectly by mining. More than half for more 40% two...
Traditional conservation techniques for mapping highly biodiverse areas assume there to be satisfactory knowledge about the geographic distribution of biodiversity. There are, however, large gaps in biological sampling and hence shortfalls. This problem is even more pronounced tropics. Indeed, use only a few taxonomic groups or environmental surrogates modelling biodiversity not viable mega-diverse countries, such as Brazil. To overcome these limitations, we developed comprehensive spatial...
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...
The Brazilian Atlantic coastal forest is one of the most heterogeneous morphoclimatic domains on earth and thus an excellent region in which to examine role that habitat heterogeneity plays shaping diversification lineages species. Here we present a molecular phylogeny rock frogs genus Thoropa Cope, 1865, native extending adjacent campo rupestre Brazil. goal this study reconstruct evolutionary history using multilocus phylogenetic analyses. Our topology reveals 12 highly supported among four...
