Batrachochytrium dendrobatidis (Bd) is the pathogenic, virulent, and transmissible chytrid fungus responsible for chytridiomycosis, an emerging invasive disease that infects amphibians and is the cause of widespread global declines and extinctions. Latin America represents a region where amphibian diversity is high and declines due to chytridiomycosis have been well documented. Although there are no well documented population collapses in northeastern Costa Rica (they are more typical of the central montane ecosystems), fragments of this lowland rainforest area are thought to show moderate to high probability of Bd occurrence. This dataset consists of chytrid surveys done for La Suerte, Costa Rica, Central America (latitude 10.43827, longitude -83.78617). The following time period was covered by the surveys: 4th June thru 15th June 2011. The following 16 species were sampled (usually 10 samples per species were taken) and referenced in time and space: Agalychnis callidryas, Agalychnis saltator, Cochranella pulverata, Craugastor fitzingeri, Craugastor polyptychus, Dendrobates auratus, Dendropsophus ebraccatus, Dendropsophus phlebodes, Hypsiboas rufitelus, Leptodactylus pentadactylus, Lithobates vaillanti, Oophaga pumilio, Pristimantis ridens, Rhinella marina, Scinax elaeochrous, and Smilisca puma. The data are organized in an MS Excel sheet and provide all relevant details as columns following the basic DarwinCore format. Results of the lab analysis are available upon request by the senior author and all details can be found online with the Omaha zoo data website (<http://biofinity.unl.edu/HDZ/amphibian/>). The reported species data provide 'presence only' (and can provide derived absence) information. These data were not obtained from any research design, do not indicate survey effort, and do not directly represent abundances or population trends. Findings do, however, provide important information in regards to prevalence levels, species infected, and spatial distributions, provided in a digital format.
The purpose of this study was to provide a first documentation of chytrid fungus Batrachocytrium dendrobatitis (Bd) prevalence at a site that otherwise had no preexisting data, is widely underpublished, and is of conservation relevance. Findings from the results will provide important information in regards to Bd prevalence levels, amphibian species infected, and spatial distributions, provided in a digital format.

Species were identified in the field using local field guides, confirmed with photos and, when necessary, by experts in the field. If available, species are named according to ITIS. If not available, species are named according to INBio Costa Rica. These are raw data and species IDs are reliable, but a check with genetic and taxonomic experts is always advised for confirmation and for latest updates.

Photos and field guides, ITIS classification
These data are collected by primary author with help from colleagues. When necessary, species identification verified by local field guide authors.
Completeness_Report: Data are complete for the survey dates compiled.
Data were collected in the vicinity of c. 5 km around the field station. The data include GPS coordinate measurements for the field station using Garmin eTrex Venture HC in latitude longitude WGS 84.
Anuran specimens were sampled opportunistically and represent presence-only data. Data was collected according to the protocol set forth by the Omaha Henry Doorly Zoo in their Amphibian Conservation Education Project. Sterile nitrile gloves were worn before handling any specimen. The ventral surface of the amphibian was swabbed with cotton and the sample placed in one milliliter of 70 percent ethanol. Each vial was labeled with a unique identification code. A photograph was taken of each sampled frog for identification purposes. Frogs were identified with the use of local field guides and, in some instances, were verified by the authors of the guides. Additional data collected include date and time of sampling, field site sampled and microhabitat, air and water (where applicable) temperature, and longitude and latitude of sampling.
