Circadian (∼ 24 h) clock regulated biological rhythms have been identified in a wide range
of organisms from prokaryotic unicellular cyanobacteria to higher mammals. These rhythms …

Virtually all species have developed cellular oscillations and mechanisms that synchronize
these cellular oscillations to environmental cycles. Such environmental cycles in biotic (eg …

The circadian clock is an autonomous oscillator that produces endogenous biological
rhythms with a period of about 24 h. This clock allows organisms to coordinate their …

This Review presents a broad overview of adaptations of truly Arctic and Antarctic mammals
and birds to the challenges of polar life. The polar environment may be characterized by …

The behavioural rhythms of organisms are thought to be under strong selection, influenced
by the rhythmicity of the environment,,,. Such behavioural rhythms are well studied in …

Coordinated daily rhythms are evident in most aspects of our physiology, driven by internal
timing systems known as circadian clocks. Our understanding of how biological clocks are …

Long-term tracking using global positioning systems (GPS) is widely used to study
vertebrate movement ecology, including fine-scale habitat selection as well as large-scale …

Daily interactions between the hypothalamic circadian clock at the suprachiasmatic nucleus
(SCN) and peripheral circadian oscillators regulate physiology and metabolism to set …

For 20 years, researchers have thought that circadian clocks are defined by feedback loops
of transcription and translation. The rediscovery of posttranslational circadian oscillators in …

The pea aphid, Acyrthosiphon pisum, is a paradigmatic photoperiodic species that exhibits a
remarkable annual life cycle, which is tightly coupled to the seasonal changes in day length …
