Species distributed across vast continental areas and major biomes provide unique model systems for studies of biotic diversification, yet also constitute daunting financial, logistic political challenges data collection such regions. The tree frog Dendropsophus minutus (Anura: Hylidae) is a nominal species, continentally in South America, that may represent complex multiple each with more limited distribution. To understand the spatial pattern molecular diversity throughout range this...
A new species of the genus Phyllodytes is described from State Bahia, in Atlantic Rain Forest Northeastern Brazil. praeceptor sp. nov. can be differentiated other by its medium size (SVL 20.7–25.8 mm males); odontoids moderately developed; vocal sac externally visible; eyes large and prominent; dorsum homogenously cream, except for a few scattered spots blotches; venter areolate with two parallel, paramedial lines larger tubercles; tubercles ventral surface thighs, largest being medial one;...
Documenting the Neotropical amphibian diversity has become a major challenge facing threat of global climate change and pace environmental alteration. Recent molecular phylogenetic studies have revealed that actual number species in South American tropical forests is largely underestimated, but also many lineages are millions years old. The genera Phyzelaphryne (1 sp.) Adelophryne (6 spp.), which compose subfamily Phyzelaphryninae, include poorly documented, secretive, minute frogs with an...
We describe a new species of the Scinax ruber clade from Northeastern Brazil that occurs in widely separated geographic areas Atlantic Forest southern Bahia state and Highland Humid Serra de Baturité, northeast Ceará state. tropicalia sp. nov. (holotype coordinates: -14.795694°, -39.172645°) is diagnosed all 75 currently recognize S. by bioacoustical morphological adult traits, such as duration (0.11–0.31 s) dominant frequency (1.59–1.85 kHz) advertisement call, snout shape rounded, nearly...
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...
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...
Abstract The relationships of the hyline tribe Dendropsophini remain poorly studied, with most published analyses dealing few species groups Dendropsophus . In order to test monophyly Dendropsophini, its genera, and currently recognized in , we performed a total evidence phylogenetic analysis. molecular dataset included sequences three mitochondrial five nuclear genes from 210 terminals, including 12 outgroup species, two Xenohyla 93 108 phenomic includes 46 one per (34 11 species). Our...
Abstract In the Brazilian Atlantic Rainforest (AF), amphibians (625 species) face habitat degradation leading to stressful thermal conditions that constrain animal activity (e.g., foraging and reproduction). Data on ecology for these species are still scarce. We tested hypothesis environmental occupation affects tolerance of amphibian more than their phylogenetic relationships. evaluated patterns 47 by assessing critical maxima warming tolerances, relating variables with ecological...
Dendropsophini is the most species-rich tribe within Hylidae with 234 described species. Although cytogenetic information sparse, chromosome numbers and morphology have been considered as an important character system for systematic inferences in this group. Using a diversity of standard molecular techniques, we describe previously unknown karyotypes genera <i>Xenohyla</i>, <i>Scarthyla</i> <i>Sphaenorhynchus</i> provide new on...
Dendropsophus gaucheri is a recently described species which inhabits open areas of the eastern part Guiana Shield and currently assigned to D. parviceps group based on presence subocular cream spot. Herein we investigate its phylogenetic position including material from type locality newly documented populations Suriname Brazil mtDNA sequences. The species, as well riveroi minimus group, were recovered nested within microcephalus implies paraphyly three groups. Such result, along with other...
We describe a new species of the Dendropsophus leucophyllatus Group from Atlantic Forest southern region State Bahia, Brazil. It can be distinguished all D. on basis morphological characters (especially its unique dorsal pattern and snout in view), advertisement calls divergence mitochondrial DNA gene sequences. The inclusion anceps group remains controversial but our phylogenetic analyses do not recover as sister to syntopic (with or without anceps). These results also highlight palimpsest...
We describe Dendropsophus ozzyi sp. nov., a new species of treefrog, tentatively included in the microcephalus Group and most notably diagnosed by presence pointed fingers an advertisement call with very high dominant frequency. The is known from three localities Brazilian Amazon forest, two on western State Pará one (the type locality) eastern Amazonas (03°56’50”S 58°26’36”W, 45 m a.s.l.).
Realistic predictions about the impacts of climate change onbiodiversity requires gathering ecophysiological data and critical thermal maxima (CTMax) is most frequently used index to assess vulnerability species. In present study, we performed a systematic review understand how acclimation altitude affect CTMax estimates for amphibian non-avian reptile We retrieved anurans, salamanders, lizards, snakes, turtles/terrapins. Data allowed perform multilevel random effects meta-analysis answer...
We describe Dendropsophus manonegra sp. nov. from the upper Amazon basin in eastern foothills of Andes Colombia (1 degree 47' 42.2" N, 75 degrees 38' 48.7" W; 1040 m a.s.l.). Phylogenetic analysis DNA sequences 2582 aligned base pairs 12S and 16S rRNA genes recovered new species as a member D. leucophyllatus group sister to bifurcus. Morphological traits, such presence pectoral glands males females, support this hypothesis. The is readily distinguished all other members by having...
