Phylogeography of the bushmaster (Lachesis muta: Viperidae): implications for neotropical biogeography, systematics, and conservation
We used mitochondrial gene sequences to reconstruct phylogenetic relationships among subspecies of the bushmaster, Lachesis muta. These large vipers are widely distributed in lowland tropical forests…
Recent introduction of a chytrid fungus endangers Western Palearctic salamanders
Results show that B. salamandrivorans is restricted to, but highly pathogenic for, salamanders and newts (Urodela), and likely originated and remained in coexistence with a clade of salamander hosts for millions of years in Asia.

An ecological niche model of past and future pika distributions highlights the influence of climate on species range and indicates that the distribution of genetic diversity may change dramatically with continued climate warming.

The evolutionary history of spotted salamander populations underscores the generality of biogeographical processes in eastern North America: despite differences in population size, glacial refugia, and vagility, similar signatures of differentiation are evident among and within widespread taxa.
Recent Asian origin of chytrid fungi causing global amphibian declines
Panzootic chytrid fungus out of Asia Species in the fungal genus Batrachochytrium are responsible for severe declines in the populations of amphibians globally. The sources of these pathogens have…

Amphibian fungal panzootic causes catastrophic and ongoing loss of biodiversity
A global, quantitative assessment of the amphibian chytridiomycosis panzootic demonstrates its role in the decline of at least 501 amphibian species over the past half-century and represents the greatest recorded loss of biodiversity attributable to a disease.
Disentangling host, pathogen, and environmental determinants of a recently emerged wildlife disease: lessons from the first 15 years of amphibian chytridiomycosis research
The ecology and evolution of Bd in the Americas is reviewed and controversies that make this disease so enigmatic are highlighted and the concept of “the Ghost of Epizootics Past” is introduced to discuss expected patterns in postepizootic host communities.

Genetic-assignment analyses revealed that interruption to seasonal migration was the mechanism underlying these patterns and underscore the sizeable impact of roads on this species, the utility of population genetics for studies of road ecology, and the need for mitigating effects of roads.
