The past decade has seen a rapid increase in the number of studies dealing with the genetic
consequences of habitat fragmentation, in large part because of the increasing accessibility …

Irrespective of geography, forest destruction and fragmentation lead to lower avian species
richness. The underlying mechanisms causing local extirpations have been studied most …

The refugial hypothesis is treated as the definitive history of Amazonian forests in many
texts. Surprisingly, this important theoretical framework has not been based on …

Abstract Knowledge of the evolutionary processes that shaped a biota is important for both
academic and conservation purposes. The objective of the present study is to analyse the …

The ecological traits of organisms may predict their genetic diversity and population genetic
structure and mediate the action of evolutionary processes important for speciation and …

Detection of the genetic effects of recent habitat fragmentation in natural populations can be
a difficult task, especially for high gene flow species. Previous analyses of mitochondrial …

Landscape genetic approaches offer the promise of increasing our understanding of the
influence of habitat features on genetic structure. We assessed the genetic diversity of the …

Abstract Six populations of Warbling Antbird (Hypocnemis cantator) currently considered
subspecies are more appropriately recognized as species, given the multiplicity of vocal …

A fundamental need in conserving species and their habitats is defining distinct entities that
range from individuals to species to ecosystems and beyond (Table; Ryder …

In the last two centuries, the development of human civilization has transformed large
natural areas into anthropogenic landscapes, making habitat fragmentation a pervasive …
