| comparative phylogeography of the atlantic forest endemic sloth (bradypus torquatus) and the widespread three-toed sloth (bradypus variegatus) (bradypodidae, xenarthra). | the comparative phylogeographic study of the maned sloth (bradypus torquatus) and the three-toed sloth (bradypus variegatus) was performed using a segment of mitochondrial dna (mtdna) control region. we examined 19 b. torquatus from two regions and 47 b. variegatus from three distant regions of atlantic forest. this first characterization of molecular diversity indicates a great diversity (b. torquatus: h = 0.901 +/- 0.039 and pi = 0.012 +/- 0.007; b. variegatus: h = 0.699 +/- 0.039 and pi = 0.0 ... | 2006 | 16502095 |
| genetic diversity in different populations of sloths assessed by dna fingerprinting. | in this study we analyzed a population of bradypus torquatus with individuals originally distributed in different localities of bahia, and two populations of b. variegatus with individuals from bahia and são paulo states. using the dna fingerprinting method, we assessed the genetic variability within and between populations. analysis of the dna profiles revealed genetic similarity indices ranging from 0.34 +/- 0.07 to 0.87 +/- 0.04. similar low levels of genetic variability were found only in is ... | 2002 | 12530188 |
| first record of hematologic values in free-living and captive maned sloths (bradypus torquatus; xenartha, bradypodidae). | bradypus torquatus is a rare and endemic sloth species from the atlantic forest, brazil. due to a lack of medical information including hematologic reference parameters for the species, hematologic baseline values were determined using samples from 14 clinically healthy b. torquatus , under captive (n = 7) and free-living (n = 7) conditions in bahia state, brazil. additionally, the morphology of the blood cells is presented, with a demonstration that the barr body chromosome may assist with sex ... | 2017 | 28749257 |
| the distributional ecology of the maned sloth: environmental influences on its distribution and gaps in knowledge. | the maned sloth bradypus torquatus (pilosa, bradypodidae) is endemic to a small area in the atlantic forest of coastal brazil. it has been listed as a threatened species because of its restricted geographic range, habitat loss and fragmentation, and declining populations. the major objectives of this study were to estimate its potential geographic distribution, the climatic conditions across its distributional range, and to identify suitable areas and potential species strongholds. we developed ... | 2014 | 25338139 |
| chromosome painting in three-toed sloths: a cytogenetic signature and ancestral karyotype for xenarthra. | xenarthra (sloths, armadillos and anteaters) represent one of four currently recognized eutherian mammal supraorders. some phylogenomic studies point to the possibility of xenarthra being at the base of the eutherian tree, together or not with the supraorder afrotheria. we performed painting with human autosomes and x-chromosome specific probes on metaphases of two three-toed sloths: bradypus torquatus and b. variegatus. these species represent the fourth of the five extant xenarthra families to ... | 2012 | 22429690 |
| characteristics of filiform, fungiform and vallate papillae and surface of interface epithelium-connective tissue of the maned sloth tongue mucosa (bradypus torquatus, iliger, 1811): light and scanning electron microscopy study. | the study of lingual surfaces and the surface of interface epithelium-connective tissue of the tongue of bradypus torquatus was performed by employing the light and scanning electron microscopy (sem) techniques. the results revealed that the rostral part of the tongue presents a round apex and covered by filiform and fungiform lingual papillae and a ventral smooth surface. it was observed that the epithelial layer of the dorsal surface possesses the basal, spinosum, granular and cornified epithe ... | 2009 | 19143682 |
| surveillance of arboviruses in primates and sloths in the atlantic forest, bahia, brazil. | from 2006 through 2014, we conducted seroepidemiological surveys on non-human primates and sloths to investigate the possible circulation of arboviruses in bahia atlantic forest, brazil. we collected a total of 196 samples from 103 leontopithecus chrysomelas, 7 sapajus xanthosternos, 22 bradypus torquatus and 7 bradypus variegatus. serum samples were tested using neutralization test and hemagglutination inhibition test to detect total antibodies against 26 different arboviruses. the overall prev ... | 2018 | 30117001 |
