Summary

These model objects are the outputs of two Bayesian hierarchical models (one for the Middle Rockies and one for the Southern Rockies) to explore the role of landscape characteristics in climate-driven ecological change and transformation. We used the rate of change for each site at 100-yr time steps as the response variable, and included elevation, CHILI, aspect, slope, and TPI as fixed effects in the models, run separately for each ecoregion. We included a random intercept of site to quantify the magnitude of site-level variation in rate-of-change that may be unaccounted for by our covariates.

Purpose

We leveraged existing open source paleorecords of vegetation change across the Middle and Southern Rockies, along with open source landscape characteristics data, to better understand what role the landscape plays in climate-driven rapid ecological change and ecological transformation.
