The organization of biological activities into daily cycles is universal in organisms as diverse
as cyanobacteria, fungi, algae, plants, flies, birds and man. Comparisons of circadian clocks …

In insects, olfaction plays a crucial role in many behavioral contexts, such as locating food,
sexual partners, and oviposition sites. To successfully perform such behaviors, insects must …

Mammals have circadian clocks in peripheral tissues, but there is no direct evidence of their
physiological importance. Unlike the suprachiasmatic nucleus clock that is set by light and …

Employing the clear, student-friendly style that made previous editions so popular, Insect
Physiology and Biochemistry, Fourth Edition presents an engaging and authoritative guide …

Organisms adapt to changing environments by adjusting their development, metabolism,
and behavior to improve their chances of survival and reproduction. To achieve such …

Circadian clocks organize behavior and physiology to adapt to daily environmental cycles.
Genetic approaches in the fruit fly, Drosophila melanogaster, have revealed widely …

A genetic screen for mutants that alter circadian rhythms in Drosophila identified the first
clock gene—the period (per) gene. The per gene is a central player within a transcriptional …

Circadian clocks are widely distributed in mammalian tissues, but little is known about the
physiological functions of clocks outside the suprachiasmatic nucleus of the brain. The retina …

Circadian clocks have evolved to synchronize physiology, metabolism and behaviour to the
24-h geophysical cycles of the Earth. Drosophila melanogaster's rhythmic locomotor …

Life on earth is shaped by the 24-h rotation of our planet around its axes. To adapt behavior
and physiology to the concurring profound but highly predictable changes, endogenous …
