Data for: A novel cricket morph has diverged in song and wing morphology across island populations

# README for data files accompanying Gallagher et al. (2023) “A novel cricket morph has diverged in song and wing morphology across island populations ” A novel cricket morph has diverged in song and wing morphology across island populations ## Data File #1: field\_data.csv A data frame with phenotypic data from field-collected male Teleogryllus oceanicus crickets. Data include geometric morphological measures of wings and song data from calling and courtship songs. Some individuals have empty cells for certain types of data due to incomplete sampling (not all males had wing, calling, and courtship data). ### Description of the data and file structure *** Descriptions of column names: maleID: unique male identifier. population: population. numID: numeric ID, unique within population. wingPC1–PC3: values for first three PCA axes from morphometric analyses. Scraper: binary presence/absence of scraper. Mirror: binary presence/absence of mirror. harp\_width: Procrustes distance (euclidean distance in tangent space) between wing landmarks 5 & 14, along x-axis. Peak\_Frequency: frequency with the greatest acoustic power. Amplitude: linear amplitude ratio (stimulus, relative to background noise). rangeA–F: relative amplitudes of six different frequency ranges based on hearing ability of T. oceanicus. Frequency.Evenness: A measure of how evenly distributed (i.e. how broadband) a song is across frequency ranges (see manuscript for details). freq\_even: Alternate abbreviation for Frequency.Evenness (see above). calling\_PC1–PC3: values for first three PCA axes from calling song analyses. courtship\_PC1–PC3: values for first three PCA axes from courtship song analyses. pronotum: values of pronotum width in mm (proxy for body size). Acoustic variables (peak frequency, amplitude, ranges A-F, frequency evenness) are repeated for various song types, including calling (\_calling), courtship chirp (\_court\_chirp), or courtship trill (\_court\_trill). ## Data File #2: kalaupapa\_lab\_field.csv A data frame with acoustic data from field and lab-reared male Teleogryllus oceanicus crickets from the Kalaupapa population on the island of Molokai. ### Description of the data and file structure *** Descriptions of column names: maleID: unique male identifier. population: population. field\_lab: whether the individual was sampled from the field or the lab. peak\_frequency\_courtship: courtship song frequency with the greatest acoustic power. ## Data File #3: song\_repeatibility.csv A data frame with acoustic data from male Teleogryllus oceanicus crickets used to measure the repeatability of song characteristics within individuals. ### Description of the data and file structure *** Descriptions of column names: maleID: unique male identifier. population: population. song\_number: that song’s number from a particular individual (1-3). peak\_frequency: calling song frequency with the greatest acoustic power. amplitude: calling song linear amplitude ratio (stimulus, relative to background noise). ## Data File #4: Raw data.zip Raw data include: Wing photographs used for wing morphometrics, labeled by population and male ID. Song recordings used for song analysis, labeled by population and male ID, organized by song type (calling vs courtship) and whether recordings were conducted in the field or the lab.
