Comportamento territorial e hierarquia de dominância de Anthracothorax nigricol...
Araújo-Silva, Lucas Eduardo; Bessa, Eduardo [UNESP]Made available in DSpace on 2022-04-28T18:56:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-06-01; Dominant species are those which delimit and defend territories from other individuals of the same or different species. Subordinate species are those which, furtive and sneakily, use sources of nectar from other individuals. This study aimed to describe the aggressive interactions between species of hu...
A dynamic continental moisture gradient drove Amazonian bird diversification
Silva, Sofia Marques; Townsend Peterson, A.; Carneiro, Lincoln Silva; Burlamaqui, Tibério César Tortola; Ribas, Camila Cherem; Sousa-Neves, TiagoThe Amazon is the primary source of Neotropical diversity and a nexus for discussions on processes that drive biotic diversification. Biogeographers have focused on the roles of rivers and Pleistocene climate change in explaining high rates of speciation. We combine phylogeographic and niche-based paleodistributional projections for 23 upland terra firme forest bird lineages from across the Amazon to derive a n...
Phenotypic and genetic structure support gene flow generating gene tree discord...
Thom, Gregory; Amaral, Fábio Raposo do; Hickerson, Michael J.; Aleixo, Alexandre; Araújo-Silva, Lucas Eduardo; Ribas, Camila CheremBefore populations become independent evolutionary lineages, the effects of micro evolutionary processes tend to generate complex scenarios of diversification that may affect phylogenetic reconstruction. Not accounting for gene flow in species tree estimates can directly impact topology, effective population sizes and branch lengths, and the resulting estimation errors are still poorly understood in wild popula...
