Endogenous circadian and exogenously driven daily rhythms of antioxidative enzyme
activities and of low molecular weight antioxidants (LMWAs) are described in various …

Circadian clocks are ubiquitous and are found in organisms ranging from bacteria to
mammals. This ubiquity of occurrence implies adaptive significance, but to date there has …

Circadian coordination of life functions is believed to contribute to an organism's fitness;
however, such contributions have not been convincingly demonstrated in any animal. The …

Circadian clocks are believed to have evolved in parallel with the geological history of the
earth, and have since been fine-tuned under selection pressures imposed by cyclic factors …

Circadian rhythms are believed to be an evolutionary adaptation to daily environmental
cycles resulting from Earth's rotation about its axis. A trait evolved through a process of …

The transparent nematode Caenorhabditis elegans can sense UV and blue-violet light to
alter behavior. Because high-dose UV and blue-violet light are not a common feature …

A series of laboratory selection experiments on Drosophila melanogaster over the past two
decades has provided insights into the specifics of life-history tradeoffs in the species and …

Surely most chronobiologists believe circadian clocks are an adaptation of organisms that
enhances fitness, but are we certain that this focus of our research effort really confers a …

The presence of artificial light at night is expanding in geographical range and increasing in
intensity to such an extent that species living in urban environments may never experience …
