“…In a cold environment, temporal information may serve mice for anticipation of the next night in which temperature lowers, and building of a nest helps to save energy and protect adults as well as offspring. Differences in daytime-dependent behaviour between laboratory and natural conditions have been described in mice, hamsters and fruitflies, suggesting a profound influence of light/dark cycle on the behavioural repertoire of model species [6,8,9]. One gene involved in the circadian clock system in flies and mice is Period1 (Per1) [10 -12].…”

Laboratory mice are well capable of performing innate routine behaviour programmes necessary for courtship, nest-building and exploratory activities although housed for decades in animal facilities. We found that in mice inactivation of the clock gene Period1 profoundly changes innate routine behaviour programmes like those necessary for courtship, nest building, exploration and learning. These results in wild-type and Period1 mutant mice, together with earlier findings on courtship behaviour in wild-type and period-mutant Drosophila melanogaster, suggest a conserved role of Period-genes on innate routine behaviour. Additionally, both per-mutant flies and Period1-mutant mice display spatial learning and memory deficits. The profound influence of Period1 on routine behaviour programmes in mice, including female partner choice, may be independent of its function as a circadian clock gene, since Period1-deficient mice display normal circadian behaviour.

“…Some rodent species that are diurnal in the field become nocturnal under certain laboratory conditions, including degus (Ebensperger et al, 2004;Kas and Edgar, 1999), hamsters (Gattermann et al, 2008), tuco-tucos (Tomotani et al, 2012), cururos (Urrejola et al, 2005), Nile grass rats (Blanchong et al, 1999) and golden spiny mice (Cohen et al, 2010). These discrepancies in circadian rhythms between the laboratory and field raise the question of whether a 'default' circadian phenotype actually exists.…”

“…First, we would like to stress that, in their natural habitat, many small rodent species typically considered as nocturnal can indeed show extensive periods in which a substantial or even the dominant fraction of their daily activity occurs during the light phase. This includes rats, mice, hamsters and even several subterranean species Gattermann et al, 2008;Harper and Bunbury, 2015;Levy et al, 2007;Tomotani et al, 2012;Urrejola et al, 2005;reviewed in Hut et al, 2012). We propose that the danger of predation might be an important factor in favoring nocturnality in rodents and other herbivorous prey species whenever they can afford it.…”

The Darwinian fitness of mammals living in a rhythmic environment depends on endogenous daily (circadian) rhythms in behavior and physiology. Here, we discuss the mechanisms underlying the circadian regulation of physiology and behavior in mammals. We also review recent efforts to understand circadian flexibility, such as how the phase of activity and rest is altered depending on the encountered environment. We explain why shifting activity to the day is an adaptive strategy to cope with energetic challenges and show how this can reduce thermoregulatory costs. A framework is provided to make predictions about the optimal timing of activity and rest of non-model species for a wide range of habitats. This Review illustrates how the timing of daily rhythms is reciprocally linked to energy homeostasis, and it highlights the importance of this link in understanding daily rhythms in physiology and behavior.

“…Studies investigating animal behaviour around the clock often reveal surprising temporal flexibility; for example, young reed warblers (Acrocephalus scirpaceus) regularly show nocturnal movements well before migration (Mukhin et al 2005) and golden hamsters (Mesocricetus auratus) are nocturnal in captivity but diurnal in nature (Gattermann et al 2008). Most behaviour is energy and time consuming, and the optimal daily routine is thought to be an adaptive compromise (Hutchinson et al 1993).…”

Sex-specific timing of mate searching and territory prospecting in the nightingale: nocturnal life of females

et al. 2009

Formal models have shown that diel variation in female mate searching is likely to have profound influence on daily signalling routines of males. In studies on acoustic communication, the temporal patterns of the receivers' signal evaluation should thus be taken into account when investigating the functions of signalling. In bird species in which diel patterns of signalling differ between males singing to defend a territory or to attract a mate, the diel patterns of mate and territory prospecting are suggested to depend on the sex of the prospector. We simulated newly arriving female nightingales (Luscinia megarhynchos) by translocating radio-tagged females to our study site. The mate-searching females prospected the area mostly at night, visiting several singing males. The timing of female prospecting corresponded to the period of the night when the singing activity of unpaired males was higher than that of paired males. In contrast to females, territory searching males have been shown to prospect territories almost exclusively during the dawn chorus. At dawn, both paired and unpaired males sang at high rates, suggesting that in contrast to nocturnal singing, dawn singing is important to announce territory occupancy to prospecting males. In the nightingale, the sex-specific timing of prospecting corresponded to the differential signalling routines of paired and unpaired males. The temporal patterns in the behaviour of signallers and receivers thus appear to be mutually adapted.
