Boreal toad survival varies by degree of attenuation and adaptation of a fungal pathogen

Batrachochytrium dendrobatidis (Bd) is a fungal pathogen responsible for dramatic declines of amphibian populations around the world. Experimental exposure studies have documented differences in host susceptibility to Bd, but variation in study designs may limit our ability to compare inferences across studies. Using laboratory-maintained pathogen cultures that may lose virulence over time (i.e., pathogen attenuation) or exposing hosts to foreign or local strains are choices that could affect hosts differently. To test how these study design choices affect resulting inference, we exposed a vulnerable anuran species, the boreal toad (Anaxyrus boreas boreas), to three strains of Bd that varied in passage history and geographic origin and measured differences on host survival. We also examined strain-specific information reported in 58 publications of Bd exposure experiments to investigate the potential for reproducibility across studies. We found that boreal toads exposed to strains with ..., , , # Data from: Boreal toad survival varies by degree of attenuation and adaptation of a fungal pathogen Dataset DOI: [10.5061/dryad.15dv41p6c](10.5061/dryad.15dv41p6c) ## Description of the data and file structure The Strain_CJS_Con_DRYAD.csv file is a file that generates a concatenated string in the last column that will input into the program MARK. ### Files and variables #### File: Strain_CJS_con_DRYAD.csv **Description:**Â ##### Variables * Filler_1: Required before identifier (id) for MARK software to separate individuals * id: Individual animal ID * Filler_2: Required after identifier (id) for MARK software to separate individuals * Day 0: Alive (1) or dead (0) on the day of sampling * Day 7: Alive (1) or dead (0) on the day of sampling * Day 14: Alive (1) or dead (0) on the day of sampling * Day 21: Alive (1) or dead (0) on the day of sampling * Day 28: Alive (1) or dead (0) on the day of sampling * WY_BUL: A 1 indicates the individual belonging to the Wyoming population an..., ,
