A combined spatial and temporal phylogeny suggests the presence of the FV3 lineage in Canada is relatively contemporary (<100 years), corroborating the hypothesis that both CMTV- and FV 3-like viruses spread to North America when the international commercial amphibian trade started.
Distribution and variation of the giant alpha anoles (Squamata: Dactyloidae) of the genus Dactyloa in the highlands of western Panama, with the description of a new species formerly referred to as D.…
Correlated morphological differences confirm the existence of a cryptic species among populations currently assigned to D. microtus, and support all six nominal taxa, but reveal considerable genetic differentiation between populations of the two highland species, D. casildae and D.microtus.
Distribution extension for Anolis salvini Boulenger, 1885 (Reptilia: Squamata: Dactyloidae), in western Panama
New localities for the lizard Anolis salvini Boulenger are reported along the Pacific slopes of the Cordillera Central in Chiriqui province and the Comarca Ngobe-Bugle of western Panama and the known geographic distribution is extended about 70 km eastwards.
Amphibian Disease Ecology: Are We Just Scratching the Surface?
There is no general consensus about the factors driving epidemiological patterns of pathogens in amphibian communities, and it is clear that the complexity and specificity of interactions between ecological factors and host–pathogen dynamics make conservation implications difficult and management decisions challenging.
Low intraspecific variation of Frog virus 3 with evidence for novel FV3-like isolates in central and northwestern Canada.
There was a lack of variation at the 2 markers across these regions, suggesting that there is a Lack of FV3 sequence diversity in Canada, which may hint at a single source of infection that has spread.
Sublethal effects of wild-type and a vIF-2α-knockout Frog virus 3 on postmetamorphic wood frogs (Rana sylvatica): potential for a stage-specific reservoir
A large number of ranaviruses have been associated with rising numbers of mass die-offs in amphibian populations around the globe, but most studies on ranavirus association have focused on larval amphibians.
A new species of Anolis (Squamata: Iguania: Dactyloidae) formerly referred to as A. pachypus from the Cordillera de Talamanca of western Panama and adjacent Costa Rica
The new species is very similar to A. magnaphallus, A. pachypus, and A. tropidolepis, which inhabit the same mountain range, but differs from these species in the coloration of the male dewlap, which is red with a yellow anterior margin.
Multi-tool diagnosis of an outbreak of ranavirosis in amphibian tadpoles in the Canadian boreal forest.

A 2-site outbreak of ranavirosis in wild anuran tadpoles in the boreal forest of Wood Buffalo National Park, Canada is reported, diagnosed by histologic and molecular techniques and highlighted the effectiveness of multi-tool approaches to mortality investigation and elucidation of pathogenesis of ranavirus in wild amphibians.
Sublethal Effects of Wild-Type and a vIF-2α-Knockout Frog virus 3 on Post-Metamorphic Wood Frogs (Rana sylvatica)
Evidence is provided that even a single short time exposure to environmentally relevant doses of Ranavirus may cause sublethal infections in post-metamorphic amphibians, thus indicating their possible role as a reservoir for this pathogen.
