README Title: Data for Evolutionary history limits species' ability to match color sensitivity to available habitat light Authors: Matthew J. Murphy* and Erica L. Westerman *University of Arkansas, Dept. of Biological Sciences mjm052@uark.edu Files: aquatic_final.csv Comma-delimited dataset of aquatic species; their maximum and minimum wavelengths of maximum sensitivity; information pertaining to maximum, minimum, average, and range in depth; and fine-scale habitat information. Includes Open Tree of Life ottids. o_max, o_min, o_range pertain to opsin lambda max (max == longest lambda max; min == shortest lambda max). d_max, d_min, d_avg, d_range pertain to depth maxima, minima, average, and range respectively. terrestrial_final.csv Comma-delimited dataset of aquatic species; their maximum and minimum wavelengths of maximum sensitivity; and fine-scale habitat information. Includes Open Tree of Life ottids. o_max, o_min, o_range pertain to opsin lambda max (max == longest lambda max; min == shortest lambda max) wide_data_102021.csv Comma-delimited dataset of all species; their maximum and minimum wavelengths of maximum sensitivity; their coarse lineage data; and coarse habitat data. Includes Open Tree of Life ottids. o_max, o_min, o_range pertain to opsin lambda max (max == longest lambda max; min == shortest lambda max). d_max, d_min, d_avg, d_range pertain to depth maxima, minima, average, and range respectively. excluded_ottids_processed.csv Comma-delimited dataset of species whose ottids were excluded from phylogenetic analysis due to being _incertae cedis_
