    DATA - Gleditsch and Sperry 2019

    No full text
    The morphological data used in Gleditsch and Sperry 2019 for analyses of morphological divergence between Oahu and the native range of four non-native frugivore species. All individuals with the "Wild" designation in the 'source' column had a correction factor applied to their measurements (see Gleditsch and Sperry 2019 for correction factors and explanation). The 'ID' column is a unique identifier for each individual. The 'year' column is the year in which the individual was collected or caught. The 'date' column is the date on which the individual was collected or caught. The 'location' is the country or island the individual was collected from or caught on. The 'source' column is whether or not the individual was a specimen from a museum or was caught in the wild. The 'range' column designates whether the individual was from the native range or the introduced range. The 'species' column is the 4-letter alpha code of the species the individual was identified as (see Gleditsch and Sperry 2019 for the alpha codes). The 'Age' column designates the age of the individual (J=juvenile, A=adult, U=unknown). The 'sex' column designates what sex the individual was determined to be (M=male, F=female, U=unknown). The other seven columns are the morphological measurements taken on each individual and correspond to the tail length, tarsus length, wing length, total culmen, nares to the tip of the culmen, bill width, and bill depth, respectively (see Gleditsch and Sperry 2019 for a description of measurements). All measurement are in millimeters. Not present in the data file are the recaptures used in the error estimation. Contact the authors for these data
