Species distribution modeling in the order Liliales.

Species distribution models are useful tools that can predict the range of a species and give insight into evolutionary and ecological trends within clades. As species occurrence data becomes more prevalent and accessible due to the increasing digitization of museum collections, more methods are needed to streamline data cleaning, processing, and analysis. In this project, we created a workflow for generating species distribution models for hundreds of species. Implemented entirely in the R language and freely available on GitHub, this workflow cleans and combines species occurrence data from BIEN and GBIF data repositories and subsequently uses climate data from WorldClim to model the climatic niche of hundreds of species. We implemented a Maximum Entropy (MaxEnt) model to estimate climatic niche. Here, we describe our workflow and present preliminary results. This workflow will be used as part of a larger study into use for future studies looking at the relationship between morphological characters and climate niche evolutionpatterns in Liliales. By examining the distributions of species with certain morphological traits, relationships between structure and environment can be revealed. Further studies will use phylogenetic techniques to map these relationships across the order Liliales in order to examine climatic niche evolution and elucidate the relationship between climatic niche and morphological change.
