Girinos do quadrilátero ferrífero, sudeste do Brasil: ecomorfologia e chave de identificação interativa
(Universidade Federal de Minas GeraisUFMG, 2011-05-19)
Tadpoles use a wide diversity of habitats with different environmental pressures. The existence of highly specialized body shapes is a strong evidence that these organisms were selected to exploit specific habitats. However, ...

A fim de investigar a vida em fadiga, modos de falha e distribuição de tensões de restaurações ultrafinas parciais, tipo tabletop, em diferentes cerâmicas, sessenta preparos padronizados foram confeccionados em resina epóxi ...
Spatial variation in bird species abundances: Environmental constraints across southern Neotropical regions
(Elsevier Gmbh, Urban & Fischer Verlag, 2013-03-23)
Climate and habitat type are frequently related with the abundance of individual species and have been hypothesized to be primary drivers of the spatial variation in species abundances at the regional scale. Our aim is to ...
Genetic relationships between Atlantic and Pacific populations of the notothenioid fish Eleginops maclovinus: the footprints of Quaternary glaciations in Patagonia
(Nature Publishing Group, 2016-04)
The genetic relationships between the Pacific and the Atlantic populations of marine coastal biota in Southern South America have been analyzed in few studies, most of them relying on a single mitochondrial locus. We ...
Urbanization altered latitudinal patterns of bird diversity-environment relationships in the southern Neotropics
(Springer, 2015-09)
Given the global expansion of urbanization, it is crucial for planning to understand how that process affects spatial patterns of diversity. At broad geographical scales, climatic conditions such as temperature or rainfall ...
Integrating Taxonomic, Functional and Phylogenetic Beta Diversities: Interactive Effects with the Biome and Land Use across Taxa
(Public Library of Science, 2015-05)
The spatial distribution of species, functional traits and phylogenetic relationships at both the regional and local scales provide complementary approaches to study patterns of biodiversity and help to untangle the ...
