Physiological variation in wild and lab-reared threespine sticklebacks from Icelandic geothermal and ambient sites

Data contain measurements of physiological variation in threespine stickleback from Icelandic populations. The data includes metabolic rates measured on individual stickleback fish across three temperatures (Metabolism.csv), inter-individual variation in distances between individuals under different temperature treatments using fish from a geothermal and ambient population (Sociability.csv), and the time individuals spent under different temperatures on their own (TemperaturePreference.csv).
