Data and Scripts for manuscript "Improving predictions of range expansion for invasive species using joint species distribution models and surrogate co-occurring species"

This data can be used to replicate the results from the manuscript "Improving predictions of range expansion for invasive species using joint species distribution models and surrogate co-occurring species". Included are R scripts and occurence datasets for running Generalized Boosted Models (GBM) species distribution models for the invasive species Cardamine impatiens, Celastrus orbiculatus, and Humulus japonicus. Also included are R scripts for building spatially explicit species co-occurrence matrices used for running joint species distribution models (specifically gjam models) in for plant communities in Minnesota based on the MN DNR plant releve dataset with a focus on incorporating the invasive species Cardamine impatiens, Celastrus orbiculatus, and Humulus japonicus as well as a case study for the native species Smilacina racemosa. The exact spatial location of each releve has been changed to a gridded position in order to protect the exact location. Raw releve data must be obtained from the MN DNR.
