Database Bd modelling for South Africa, Lesotho and eSwatini

This dataset was used to create a predictive distribution map of Batrachochytrium dendrobatidis in South Africa, based on lineage. It contains records obtained from published resources, as well as records from fieldwork done. Lineage was identified using published lineage-specific primers, in conjunction with confirmed lineage typing by whole genome sequencing from O'Hanlon et al. 2018., We modelled lineage distributions using Maxent (version 3.4.4;(Phillips et al., 2006) and algorithms described by Elith et al. (2011) to correlate environmental parameters with the presence of either Bd lineage. A database for all known Bd records  for South Africa, Lesotho and Eswatini was created with the following information: locality and coordinates of sample origin, sample size, prevalence of Bd, lineage found (if available), date of sampling, and host genus and species name. Bioclimatic variables used for modelling were obtained from WorldClim (https://www.worldclim.org/data/bioclim.html) and the contribution of the different variables are given in Table 1. Maxent used 80 % of the positive records for training of the model and the remaining 20 % to test for accuracy of predictions. Model replications were set to 100 using subsample, with the regularisation multiplier set to 1. Random seed was set to true with all other settings left at default.
Model performances were evaluated u..., Maxent v3.4.4

This dataset contains records from *Bd* surveillance and isolation work. The records originate from publicly available, peer reviewed articles, along with our own fieldwork records. Isolates from our fieldwork has also been entered into the database for whole genome sequencing that has been published with O'Hanlon *et al.* 2018. Within the dataset the country, common name for site, total number of samples taken, the number of samples positive and negative, the lineage (if available from the evidence) coordinates, and the date of collection is provided. The family, genus and species names of the sampled individuals is also given.
Please note that any site was categorised as POSTIVE, if even a single individual tested positive.

\"None\" indicates where no positives were found.

\"Not Available\" refers to historical samples included for which the lineage was not available.
