Abstract
Abstract Plasticity of circadian rhythm was investigated for the model species desert hamster (Phodopus roborovskii) under natural conditions in the Alashan Desert using the radiofrequency identification (RFID) technique, that is, animals were caught in the field and marked with passive transponders, and burrows were equipped with integrated microchip readers and photosensors for detection of movements into or out of the burrow. Additionally, video observations with infrared cameras were conducted at feeding sites to verify RFID data and analyze interspecific behavior. Composition of the rodent community changed during observation periods from a midday gerbil (Meriones meridianus)-dominated community to a desert hamster (P. roborovskii)-dominated community in 2009 and from a northern three-toed jerboa (Dipus sagitta)-dominated community to a hamster-dominated community in 2010. Activity pattern of hamsters was clearly affected by species composition. In the hamster-dominated community, activity started 1....
