| nuclear and mitochondrial phylogeography of the atlantic forest endemic xiphorhynchus fuscus (aves: dendrocolaptidae): biogeography and systematics implications. | we studied the intraspecific evolutionary history of the south american atlantic forest endemic xiphorhynchusfuscus (aves: dendrocolaptidae) to address questions such as: was the diversification of this bird's populations associated to areas of avian endemism? which models of speciation (i.e., refuges, river as barriers or geotectonism) explain the diversification within x. fuscus? does the genetic data support subspecies as independent evolutionary units (species)? we used mitochondrial (n=34) ... | 2008 | 18849002 |
| does scale matter? the influence of three-level spatial scales on forest bird occurrence in a tropical landscape. | consequences of habitat fragmentation for species occurrence are amongst the most important issues in landscape and conservation ecology. empirical and theoretical studies have demonstrated that the total amount of habitat, patch size and connectivity have nonlinear effects on species survival on multiple spatial and temporal scales. therefore, population models need to incorporate multiple scales, which can be extremely valuable to prioritizing conservation efforts in these changing landscapes. ... | 2018 | 29912911 |
