Ranavirus impact and environmental drivers of population decline in Phyllomedusa distincta

Résumé fourni par la source

Overview This repository provides the raw datasets used to investigate the impacts of a Ranavirus epizootic on populations of Phyllomedusa distincta and the environmental drivers associated with disease outbreaks and infection. The data span a multi-decadal monitoring effort conducted at RPPN Rã-bugio (Santa Catarina, Brazil), encompassing pre-epizootic and epizootic phases of the outbreak. Together, the datasets support three complementary analytical frameworks: Decline modelling framework: long-term monthly reproductive output across disease phases Mortality outbreak modelling framework: daily mortality events Disease infection framework: individual-level Ranavirus detection and viral load in larval P. distincta The data are consistent with recurrent ranavirosis-driven mass mortality, supported by gross pathological lesions, histopathological evidence, and molecular detection, with the infecting agent belonging to a globally distributed Ranavirus rana1 clade. Outbreak probability was negatively associated with antecedent relative humidity, suggesting that drier conditions may facilitate disease progression. These recurrent mortality events coincided with the decline in P. distincta reproductive output.
