These data represent capture mark recapture data from toads, and results of testing for Bd (Batrachochytrium dendrobatidis) the pathogen that causes amphibian chytridiomycosis on individuals. The data span from 2004-2016 at three sites in Montana where boreal toads were declining. The data also include temperature measurements at the sites and information on the egg counts and Bd prevalence from Columbia spotted frogs that are co-occurring at one of the sites.
Evaluating regulations and surveillance as risk-mitigation to the emerging amphibian pathogen Bsal- Data release
Results of a literature search performed December 1, 2020. The tables in this document summarize the publications fitting in this search criteria and are split into the publications that update the list of international species that could carry Bsal (Appendix 1 Table S1). Number of individual live amphibians imported in categories of urodelan (salamander, newt, and related taxa) species restricted under the interim regulations and not listed, species not listed on the regulations that have had Bsal detected, notably Bombina spp., anuran species in the genus Rana, and Xenopus (including African clawed frogs) as a comparison of species not thought to be susceptible to Bsal, but commonly imported (Appendix 3 Table...
ABSTRACT: The fungal pathogen Batrachochytrium dendrobatidis (Bd) causes chytridiomycosis, a disease implicated in amphibian declines on 5 continents. Polymerase chain reaction (PCR) primer sets exist with which amphibians can be tested for this disease, and advances in sampling techniques allow non-invasive testing of animals. We developed filtering and PCR based quantitative methods by modifying existing PCR assays to detect Bd DNA in water and sediments, without the need for testing amphibians; we tested the methods at 4 field sites. The SYBR based assay using Boyle primers (SYBR/Boyle assay) and the Taqman based assay using Wood primers performed similarly with samples generated in the laboratory (Bd spiked...
These data represent capture mark recapture data along with associated disease status for boreal toads (Anaxyrus boreas) from Wyoming and Montana from 2004-2016 and four frog species (Rana draytonii, R. muscosa, R. pretiosa, R. sierrae) from 2001-2016.
Production of polyclonal antibodies to Batrachochytrium dendrobatidis and their use in an immunoperoxidase test for chytridiomycosis in amphibians
We investigated population dynamics in boreal toads relative to abiotic (fall temperatures and snowpack -the covariates provided here) and biotic (the abundance of another anuran host,data provide here) characteristics of the local environment at 6 sites in Wyoming, USA. We used capture-recapture data (i.e., 1 or 0, provided here) and a robust design multi-state model framework that incorporates disease state uncertainty to assess our a priori hypotheses about interactions among covariates (temperature, snowpack and presence of spotted frogs) and boreal toad survival. Files include: br_bd.csv, disease data; br_cmr.csv, capture-mark recapture data (1,0); br_cov.csv, soil and snow information detailed in this file;...
