Allopatric and sympatric diversification within roach (Rutilus rutilus) of large pre‐alpine lakes

This is the data for the study entitled "Allopatric and sympatric diversification within roach (<em>Rutilus rutilus</em>) of large pre‐alpine lakes" published in the Journal of Evolutionary Biology https://doi.org/10.1111/jeb.13502 . The dataset consists of three files: <strong>Morphology.txt </strong> Morphology data from seven Swiss lakes. Given are the individual ID, the respective lake, the habitat classification, grouped habitat classification, length of each fish (mm), and the raw x and y coordinates for 11 landmarks. Geometric morphometric landmarks were set as follow: 1) anterior tip of snout, 2) anterior tip of lower jaw, 3) anterior, and 4) posterior point of operculum, 5) junction where the dorsolateral part of the head and body fuse, anterior insertion points of the 6) pectoral, 7) pelvic, and 8) anal fin, 9) ventral and 10) dorsal junction of the caudal peduncle and tail, 11) anterior insertion of the dorsal fin. <strong>Stable_isotopes.txt </strong> Morphology data from five Swiss lakes. Given are the individual ID, lake, baseline corrected delta 13C values. <strong>Stable_isotopes_baselines.txt </strong> Morphology data from five Swiss lakes. Given are the lake, the tissue used, delta 13C values.
