Data_Sheet_1_Emerging threat of ranavirus: prevalence, genetic diversity, and climatic drivers of Ranavirus (Iridoviridae) in ectothermic vertebrates of Asia.pdf

, 2023
IntroductionRanavirus disease, caused by viruses within the genus Ranavirus (Iridoviridae), is considered a globally emerging infectious disease linked to mass mortality events in both wild and cultured ectothermic vertebrates.

Screening of a long-term sample set reveals two Ranavirus lineages in British herpetofauna.

PLoS ONE, 2017
Reports of severe disease outbreaks in amphibian communities in mainland Europe due to strains of the common midwife toad virus (CMTV)-like clade of Ranavirus are increasing and have created concern due to their considerable population impacts.

Disentangling Temporal and Environmental Effects on Hematological Values in Prairie Rattlesnakes (Crotalus viridis)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 727-734, August 2026.
ABSTRACT Hematologic assessment is a common clinical tool used to characterize both individual and population health. In ectothermic organisms, the hematologic response is influenced by external factors such as temperature and season, especially in temperate species. Yet, specific environmental effects have received little direct attention.

Aquatic eDNA can advance monitoring of a small‐bodied terrestrial salamander and amphibian pathogen

Environmental DNA, 2022
Successful conservation efforts for threatened species depend on accurate characterization of their distribution, habitat use, and threats. However, surveillance can be challenging for species with small size, cryptic coloring, or elusive behavior ...

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

Animal Conservation, Volume 29, Issue 4, Page 379-392, August 2026.
The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...

Prevalence and Distribution of Ranavirus in Amphibians From [PDF]

, 2019
Several infectious diseases are threatening amphibian species worldwide and have resulted in massmortality events across the globe. An emerging group of viral pathogens (ranaviruses) are documented to cause die-offs in amphibian populations worldwide ...

Microbial metacommunity ecology: Using null models and networks to understand assembly in a salamander disease system

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract Animals host diverse microbiomes crucial for their health, which subsequently influence their function in ecosystems. Metacommunity theory offers a useful framework to understand the processes driving host‐associated microbiome assembly across scales, linking regional environmental processes to local host–microbial processes.

Heterogeneities in the infection process drive ranavirus transmission

Ecology, 2017
AbstractTransmission is central to our understanding and efforts to control the spread of infectious diseases. Because transmission generally requires close contact, host movements and behaviors can shape transmission dynamics: random and complete mixing leads to the classic density‐dependent model, but if hosts primarily interact locally (e.g ...

Transmission dynamics of the amphibian ranavirus Ambystoma tigrinum virus [PDF]

Diseases of Aquatic Organisms, 2007
Transmission is central to pathogen fitness and strongly influences the impact of pathogens on host populations. Particularly important to transmission dynamics is the distinction between direct transmission requiring close physical contact (e.g. bumping, fighting, or coughing) and indirect transmission from environmental sources such as contaminated ...
