Combining nuclear (nuDNA) and mitochondrial DNA (mtDNA) markers has improved the
power of molecular data to test phylogenetic and phylogeographic hypotheses and has …

The study of reproductive isolation and species barriers frequently focuses on mitochondrial
genomes and has produced two alternative and almost diametrically opposed narratives. On …

Predicting past distributions of species climatic niches, hindcasting, by using climate
envelope models (CEMs) is emerging as an exciting research area. CEMs are used to …

Abstract The Indochinese Peninsula is recognized as one of the key global biodiversity
hotspots. The amphibian fauna of Indochina (including Vietnam, Laos, Cambodia and …

Many biodiversity hotspots are located in montane regions, especially in the tropics. A
possible explanation for this pattern is that the narrow thermal tolerances of tropical species …

Background The concept of a tree of life is prevalent in the evolutionary literature. It stems
from attempting to obtain a grand unified natural system that reflects a recurrent process of …

Here we present an objective, repeatable approach to delineating species when
populations are divergent and highly structured geographically using the Californian …

One of the most important hotspots of herpetological biodiversity in the United States,
California is home to many endemic amphibians and reptiles found nowhere else on earth …

Discontent about changes in species classifications has grown in recent years. Many of
these changes are seen as arbitrary, stemming from unjustified conceptual and …

Partitioned Bayesian phylogenetic analyses of routine genetic data sets, constructed using
MrBayes, can become trapped in regions of parameter space characterized by …
