Variation in dispersal traits and geography predict loss of ranges due to climate change in cold-adapted amphibians

Dispersal ability may play a major role in determining whether a species will persist under climate change. We used models of dispersal, employing a wide range of intrinsic species-specific dispersal factors, in conjunction with ecological niche models (ENM) and climate predictions to simulate whether distributions of North American cold-adapted amphibians will increase or decrease, and which aspects of dispersal most influence this prediction. We used ENM values as a proxy for habitat suitability, predicted a changing climate under three shared socio-economic pathways (SSP245, SSP370, and SSP585) representing three carbon emission scenarios, and conducted a sensitivity analysis on the effect of dispersal factors on range dynamics. We then used simulations focused only on the southern edge of ranges to determine the likelihood of individuals colonizing towards the core. Predicted range shifts depended on emission scenario, dispersal factors, and species’ initial geography. Inclusion of ..., Input files for MigClim Simulations.

## Description of the data and file structure

1\) CSV file that has GBIF DOI information.

2\) Input files for recreating simulation scenarios, broken up by shared-socioeconomic pathway (SSP) provided as GeoTIFF files (.tif) with embedded metadata (e.g. coordinate reference system) that were derived by making Species Distribution Models and predictions with Maxent.

Within the three directories of the SSPs, file names start with species name shorthand from the paper (ABMA, ANBO, ANHE, LISY, PSMA, RALU) represent the 6 species (*Ambystoma macrodactylum*, *Anaxyrus boreas, Anaxyrus hemiophrys, Lithobates sylvaticus, Pseudacris maculata,* and *Rana luteiventris*).

After the prefix for the species, files ending with \"ini_final*\" are the initial distribution inputs for the MIGCLIM...,
