Field, clinical, and molecular studies jointly suggest that the etiological agent of recent salamander mortalities is a highly infectious novel ranavirus.
INTRASPECIFIC RESERVOIRS: COMPLEX LIFE HISTORY AND THE PERSISTENCE OF A LETHAL RANAVIRUS
It is suggested that larval epidemics amplify virus prevalence and sublethally infected metamorphs (re)introduce the virus into uninfected larval populations, and intraspecific reservoirs may explain the persistence of parasites in and declines of small, isolated amphibian populations.

Results from experimental exposure trials indicate that multiple host species may be involved in the ecology of ATV- and FV3-like viruses, and that each virus is capable of infecting several amphibian species that share breeding habitats.
Transmission dynamics of the amphibian ranavirus Ambystoma tigrinum virus.
The data suggest that ATV is efficiently transmitted by direct interactions between live animals as well as by necrophagy and indirectly via water and fomites, and revealed an important temporal aspect of infectiousness: larval salamanders become infectious soon after exposure to ATV and their propensity to infect others increases with time.
Ranavirus: past, present and future
The ecology and evolution of ranavirus–host interactions, potential reservoirs, transmission dynamics, as well as immunological and histopathological responses to infection are examined.

The host range and geographic distribution of Bd and ranaviruses were explored in the Taiga Plains ecoregion of the Northwest Territories, Canada, in 2007 and 2008, and both pathogens were detected, greatly extending their known geographic distributions.
Diet and Habitat of Mountain Woodland Caribou Inferred from Dung Preserved in 5000-year-old Alpine Ice in the Selwyn Mountains, Northwest Territories, Canada

A MODEL HOST-PATHOGEN SYSTEM FOR STUDYING INFECTIOUS DISEASE DYNAMICS IN AMPHIBIANS: TIGER SALAMANDERS (AMBYSTOMA TIGRINUM) AND AMBYSTOMA TIGRINUM VIRUS
The tiger salamander ‐ ATV system offers a model for studying the host-pathogen interactions thought to be threatening some amphibian populations with extinction, and could be the most compelling example to date of how a pathogen can act globally and rapidly to cause widespread extinctions.
Mortality Rates Differ Among Amphibian Populations Exposed to Three Strains of a Lethal Ranavirus
The need to minimize translocations of amphibian ranaviruses, even among conspecifc host populations, is highlighted, and the importance of considering intraspecific variation in endeavors to manage wildlife diseases is highlighted.
