Code for manipulating and analyzing lichen data from the FIA.
Data Derived data tables for conducting final analyses.
OLD_scripts: Scripts used in prior versions of the project, including SEMs and analysis of soil attributes.
cluster_scripts: Scipts that were run on the computing cluster, including model dredging, sems, calculation of regional species richness
download_data: Scripts for downloading data from FIA and CNALH websites and conducting quality control (e.g. taxonomic revisions).
format_data: Scripts for calculating environmental covariates and richness estimates and combing FIA data sets. Includes: forest structure attributes, regional species richness, local richness, solar insolation, tree species composition, and climate variables.
analysis.R: Contains variance partitioning and model averagaing analysis reported in Coyle & Hurlbert "Environmental optimality, not heterogeneity, drives regional and local species richness in lichen epiphytes"
fia_lichen_analysis_function.R: Contains functions used in analyses.
load_data.R: Loads data needed to conduct analyses into an R workspace.
make_data_tables_for_analysis.R: Combines lichen data and environmental data into tables for analysis (see Data directory).
make_richness_maps.R: Plots local and regional macrolichen species richness as maps.
