Data from: Multi-scale model of regional population decline in little brown bats due to white-nose syndrome

The introduced fungal pathogen Pseudogymnoascus destructans is causing decline of several species of bats in North America, with some even at risk of extinction or extirpation. The severity of the epidemic of white-nose syndrome caused by P. destructans has prompted investigation of the transmission and virulence of infection at multiple scales, but linking these scales is necessary to quantify the mechanisms of transmission and assess population-scale declines. We build a model connecting within-cave disease dynamics of little brown bats to regional scale dispersal, reproduction, and disease spread, including multiple plausible mechanisms of transmission. We parameterize the model using the approach of plausible parameter sets, by comparing stochastic simulation results to statistical probes from empirical data on within-cave prevalence and survival, as well as between-cave spread across a region. Our results are consistent with frequency-dependent transmission between bats, support an important role of environmental transmission, and show very little effect of dispersal among colonies on metapopulation survival. The model also offers a generalizable method to assess hypotheses about cave-to-cave transmission and to identify gaps in knowledge about key processes, and could be expanded to include additional mechanisms or bat species as research on this detrimental fungus progresses.Multiscale model of white-nose syndrome code publishedThis R script contains the code that generates simulations, distills output, and draws figures. All other files in this archive (except for WNSBats_PowerLaw.R) are output of parts of this code. They have been included here because they represent the summarization of computationally intensive simulations that could not be included in the archive due to file size limitations. Some of the figures require these "raw" output files, if needed an alternate method of sharing can be arranged with the authors.WNSBats_PowerLawThis R script tries fitting alternative distributions to the bat dispersal data from Norquay et al. 2013. Conclude that a uniform distribution is as consistent as other possibilities. It also looks at alternative distributions for NY little brown bat population sizes from Turner et al. 2011, this can then be used to produce random versions of the regional bat population.READMEDescribes scripts and the outputs contained in .zip fileMultiscale model of white-nose syndrome outputSummarized output from the simulations.Funding provided by: National Science FoundationCrossref Funder Registry ID: http://dx.doi.org/10.13039/100000001Award Number: EF-144241
