Avian faunas vary greatly among montane areas; those at high latitudes are biologically
impoverished, whereas those of some low-latitude mountains are biologically very complex …

Molecular studies of speciation in birds over the last three decades have been dominated by
a focus on the geography, ecology, and timing of speciation, a tradition traceable to Mayr's …

A biogeographic regionalisation of the Neotropical region is proposed as a hierarchical
classification of sub-regions, dominions, provinces and districts. This regionalisation is …

The fish faunas of continental South and Central America constitute one of the greatest
concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living …

Seasonally dry tropical forests have been largely ignored in discussions of vegetation
changes during the Quaternary. We distinguish dry forests, which are essentially tree …

Phylogeographic endemism, the degree to which the history of recently evolved lineages is
spatially restricted, reflects fundamental evolutionary processes such as cryptic divergence …

We suggest Milankovitch climate oscillations as a common cause for geographical patterns
in species diversity, species' range sizes, polyploidy, and the degree of specialization and …

Aim To examine how the genetic diversity of selected taxa of forest‐dwelling small mammals
is distributed between and within the major rain forest domains of Amazonia and Atlantic …

Molecular phylogenetic studies have become a major area of interest in plant systematics,
and their impacts on historical biogeographic hypotheses are not to be disregarded. In …

We analyzed the rate at which postzygotic incompatibilities accumulate in birds. Our
purposes were to assess the role of intrinsic F1 hybrid infertility and inviability in the …
