The Impact of Conservation on the Status of the World’s Vertebrates
Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups.
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.

This work addresses the evolutionary causes of the mid-elevational diversity hump in the most species-rich clade of salamanders, the tropical bolitoglossine plethodontids, and presents a new phylogeny for the group based on DNA sequences from all 13 genera and 137 species.
Molecular diversification of salamanders of the tropical American genus Bolitoglossa (Caudata : Plethodontidae) and its evolutionary and biogeographical implications
South America was invaded by members of one clade, Eladinea, which is infer to have dispersed to South America prior to closure of the Panamanian Portal, and the existence of large genetic diversity within morphologically homogeneous taxa is uncovered.
Phylogenetic relationships of Pelobatoidea re-examined using mtDNA.

These terrestrial microhabitat specialists have largely disappeared from multiple sites in western Guatemala, including in well-protected areas, suggesting that the phenomenon cannot be explained solely by localized habitat destruction.
Extreme morphological and ecological homoplasy in tropical salamanders
A robust phylogenetic hypothesis, based on sequences of three mtDNA genes, finds Lineatriton to be deeply nested within a clade characterized by generalized ecology and morphology, and Surprisingly, geographically separated populations of L. lineolus are not monophyletic, but are sister taxa of different species of the morphologically generalized genus Pseudoeurycea.
Amphibian Population Declines in Latin America: A Synthesis 1
The loss of global amphibian biodiversity has been well documented in recent years. The greatest information from Latin America came from countries such as Costa Rica, Panama, Ecuador, and Puerto…

The two most highly infected individuals were the endangered Ambystoma mexicanum, from a captive colony, and Pachymedusa dacnicolor, purchased at a pet shop.
Amphibian Declines in Latin America: Widespread Population Declines, Extinctions, and Impacts 1
Amphibian populations are in decline throughout Latin America; all families of frogs have experienced declines, but the species associated with aquatic habitats in upland areas have been most…
