Circadian rhythms
- Identification of novel circadian transcripts in the zebrafish retina
Summary: Characterization of the day and night transcriptome of the adult zebrafish retina reveals novel circadian transcripts.
- Cold temperature represses daily rhythms in the liver transcriptome of a stenothermal teleost under decreasing day length
Summary: Transcriptomic profiling of liver tissue in a cold-adapted fish suggests tight coupling of temperature responses and daily rhythms.
- Waiting for the Sun: the circannual programme of reindeer is delayed by the recurrence of rhythmical melatonin secretion after the arctic night
Summary: Exposure to constant light or constant darkness accelerates the onset of spring physiology in overwintering reindeer; this has implications for current models of circannual time-keeping in mammals.
- Effects of photophase illuminance on locomotor activity, urine production and urinary 6-sulfatoxymelatonin in nocturnal and diurnal South African rodents
Summary: Daytime light intensity affects physiological and behavioural functions of not only diurnal but also nocturnal small mammals.
- Adaptations to polar life in mammals and birds
Summary: Polar animals are well adapted to the hardships of polar life.
