... 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...

..., 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...
