Offset between GPS collar-recorded temperature in moose and ambient weather station data

摘要: GPS collar-recorded temperature is often considered as a proxy for the ambient in wildlife ecology studies, yet few studies actually test its reliability well correlation with temperature. Here, we address this question and demonstrate strong between collar weather station data, indicating that sensor data can be regarded reliable index of air Using obtained from 384 free-ranging moose equipped collars latitude 57° N to 68° Sweden, analyzed 1,467,361 paired observations nearest official Swedish Meteorological Hydrological Institute station. We found systematic offset varied across months, being larger during warm summer months than winter period. an average .91 (r s; range .75 .93, median .91) Thus, sensors in, e.g., collar, may used study animal behavior, movement habitat choice relation This aligns calls using animals not only subjects but also samplers environment. It opens up possibilities large-scale projects on physiology absence ground measuring stations higher spatial scales like home landscape. As application temperature, show changes patterns seem highly influenced by temperature-induced heat stress experience summer.
