... sticklebacks ( Gasterosteus aculeatus ) at the behavioural and molecular levels. Although their behaviour, ecology and evolution are well studied, information on their circadian rhythms are scarce. We quantified the daily locomotor activity rhythm under a light:dark cycle (LD) and under constant darkness (DD...

Summary: Changes in body composition, activity and corticosterone during a captive experiment demonstrate that a nomadic avian migrant is not sensitive to changes in food availability, but rather escapes low-resource areas.

The microbiological status of the flies had a small or no effect on anxiety-like behavior (centrophobism) or circadian rhythmicity of locomotor activity, but axenic flies tended to sleep for longer and displayed reduced sleep...

..., THs may represent a reliable indicator for FMR. To test this hypothesis, 10 Shetland pony mares were kept under semi-extensive central European conditions. During the winter season, one group was fed 60% and one group 100% of their maintenance energy requirements. We measured FMR, locomotor activity...

In summer, ponies showed a considerably higher field metabolic rate (FMR; 63.4±15.0 MJ day –1 ) compared with food-restricted and control animals in winter (24.6±7.8 and 15.0±1.1 MJ day –1 , respectively). During summer, locomotor activity, resting heart rate and total water turnover were...

Food intake was measured during the discrete intervals 0–2 and 2–8 h, the sum of which represents the cumulative interval 0–8 h, as previously described ( de Pedro et al., 1998b ). Locomotor activity was recorded in groups of six fish...

The daily expression profiles of cell cycle markers ( Ccnd1 , Ccne1 and Pcna ) and circadian clock genes ( Per2 and Clock ) were monitored in liver and esophagus (low and high proliferation index, respectively) of BALB/c mice. Locomotor activity displayed a 24 h rhythm, establishing the circadian...
