Abstract The End‐Permian Mass Extinction marked a critical turning point in Earth's history, and the biological recovery that followed crisis led to emergence of several modern vertebrate invertebrate taxa. Even considering importance Early Triassic biotic for evolution faunas floras, our knowledge this event is still hindered by sparse sampling crucial geological formations. This leaves understanding ecosystems fundamentally biased toward productive historically well‐explored units. Recent...
Didelphis aurita and D. albiventris are widely distributed in South America, with a range of sympatry the limit their distribution, particularly Araucaria mixed ombrophilous forest southern Atlantic Forest.We investigated spatial, feeding, time use between these morphologically similar species remnant Brazil for one year.We tested hypothesis that when segregate each other space use, diet, and/or activity time.We expect they primarily dimension as occurs Australian congeneric marsupials.We...
Much evidence suggests that Amazonia and the Atlantic Forest were connected through at least three dispersion routes in past: Eastern route, central Western route. However, few studies have assessed use of these based on multiple species. Here we present a compilation mammal species potentially dispersed between two forest regions which may serve to investigate connections. We evaluate present-day geographic distributions mammals occurring both likely connective forests. classified per...
Amazonian mammal diversity is exceptionally high, yet new taxonomic discoveries continue to be made and many questions remain for understanding its diversification through time space. Here we investigate the of spiny rats in genus Makalata, whose species are strongly associated with seasonally flooded forests, watercourses islands. We use a biogeographical approach based on mitochondrial cytochrome b gene divergence estimation reconstruction ancestral areas events. Our findings indicate an...
Abstract Movements under environmental structures and on supports, the use of shelters by Akodon montensis were assessed using spool-and-line technique. a few individuals Thaptomys nigrita , Brucepattersonius iheringi Oligoryzomys nigripes also briefly described. often used fallen logs, lianas ferns as climbing supports for movements. The species moved different with differing frequencies, greater dense litter followed branches. studied sigmodontine compositions structures, differed in...
Abstract: The Neotropics is one of the most diverse regions globe in terms plants and animal species. Regarding microbial world, however, little known about diversity biogeography patterns microorganisms Neotropics. several taxonomic groups still missing and/or incomplete, such as protists. Despite hard identification protists, advance molecular techniques (e.g., metabarcoding) have allowed to better explore distribution protistan groups. Our goal here was summarize available information...
Abstract Cyclopes didactylus , the smallest of all anteaters, inhabits Amazonian and Atlantic forests with an apparently disjunct distribution. Yet, phylogeography reveals historical connections through Northeast Region Brazil. Its populations in this region are classified by Red List Threatened Species as Data Deficient a trend towards decline. However, Brazil has large sampling gap, potential distribution species yet to be evaluated. We investigated C. evaluate hypothesis between estimate...
Abstract Landscape characteristics can influence gene flow depending on the species ability to disperse. This imposes different levels of resistance movement, determining genetic structure and diversity populations. Waterfalls rapids in Amazon basin have been suggested as contributing factors diversification freshwater species, including turtles. Thus, along some main rivers Brazilian Amazon: Juruá, Madeira, Amazonas, Trombetas, Tapajós, Xingu, Tocantins, Araguaia, we evaluated spatial...
