The most comprehensive study on amphibian chytridiomycosis in southeast Asia to date was conducted by Swei et al. (2011), who screened over 3,000 individuals and found only 2.35% were positive for Bd. Those individuals observed to be Bd-positive were sampled from Indonesia (0.25% infection rate), Laos (0.73%), Malaysia (0.90%), and the Philippines (8.01%). Although Philippine samples showed a higher infection rate in the study, the infected individuals came from a single, highly disturbed mountain on Luzon Island (Swei et al. 2011). Given the unique biogeographic history of the Philippine archipelago, and its importance to global amphibian diversity as a megadiverse nation and biodiversity hotspot (Myers et al. 2000), additional studies are needed across a broader region of the country to better evaluate the prevalence of infectious amphibian diseases. Here, we present novel data on the presence and distribution of both Bd and RV pathogens among wild amphibian populations on the islands of Calayan, Camiguin Norte, Luzon, and Negros in the central and northern Philippines. 

ABSTRACT MotivationSNAPSHOT USA is an annual, multicontributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of species interactions on daily activity patterns. Main Types of Variables ContainedSNAPSHOT USA 2019–2023 contains 987,979 records of camera trap image sequence data and 9694 records of camera trap deployment metadata. Spatial Location and GrainData were collected across the United States of America in all 50 states, 12 ecoregions and many ecosystems. Time Period and GrainData were collected between 1st August and 29th December each year from 2019 to 2023. Major Taxa and Level of MeasurementThe dataset includes a wide range of taxa but is primarily focused on medium to large mammals. Software FormatSNAPSHOT USA 2019–2023 comprises two .csv files. The original data can be found within the SNAPSHOT USA Initiative in the Wildlife Insights platform.
