Natural entrainment without dawn and dusk: the case of the European ground squirrel (Spermophilus citellus).
Observational data collected in the field and in enclosures show that diurnal, burrow-dwelling European ground squirrels (Spermophilus citellus) never were above ground during twilight at dawn or at dusk. The animals emerged on average 4.02 h (SD = 0.45) after civil twilight at dawn and retreated in their burrows on average 2.87 h (SD = 0.47) before civil twilight at dusk. Daily patterns of lig...
متن کاملEctoparasites of the ground squirrel (Citellus citellus (L.)) in Turkey.
A total of 100 ground squirrels, Citellus (C.) citellus were trapped in rural regions of Konya in order to determine the presence of ectoparasites. Of these C. citellus examined, 16% (16/100) were infected with at least one ectoparasite species. Two types of ectoparasites were found including 10% fleas and 7% ticks. Only two flea species were found on C. citellus including Nosopsyllus fasciatus...
متن کاملNonphotic entrainment in a diurnal mammal, the European ground squirrel (Spermophilus citellus).
Entrainment by nonphotic, activity-inducing stimuli has been investigated in detail in nocturnal rodents, but little is known about nonphotic entrainment in diurnal animals. Comparative studies would offer the opportunity to distinguish between two possibilities. (1) If nonphotic phase shifts depend on the phase of the activity cycle, the phase response curve (PRC) should be about 180 degrees o...

15 صفحه اولHibernation effects on memory in European ground squirrels (Spermophilus citellus).
Effects of hibernation on memory were tested in European ground squirrels (Spermophilus citellus). The animals were trained in summer to successfully accomplish two tasks: a spatial memory task in a maze and an operant task on a feeding machine. One group hibernated normally, and the other was prevented from hibernation by maintaining ambient temperature at 22 degrees C. In spring, the same tas...
