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 …

A synthesis of ecological data available for subterranean fishes throughout the world is
presented, and comparatively analyzed in an evolutionary context. Methods of ecological …

Cave-adapted animals are characterized by extreme reduction or complete absence of
eyes, reflecting their lack of exposure to daylight. Given the overall constancy of abiotic …

The locomotor activity of the millipede Glyphiulus cavernicolus (Spirostreptida), which
occupies the deeper recesses of a cave, was monitored in light-dark (LD) cycles (12h light …

The evolutionary adaptations of the organisms which inhabit the unusual and fragile
ecosystems within caves are of inherent interest to both biologists and laymen. Cave …

Caves and other associated subterranean habitats represent some of the most challenging
environments on Earth. Despite many significant abiotic and biotic obstacles to overcome …

Publisher Summary Biological rhythms are one of the most intriguing and exciting research
fields in biology. Aquatic organisms are not exceptions; many studies have been devoted to …

Cavefish are vertebrates living in extreme subterranean environments with no light,
temperature changes, and limited food. Circadian rhythms in these fish are suppressed in …

The oviposition rhythm of individual flies of Drosophila melanogaster from a population
maintained in an aperiodic environment (with light, temperature, humidity, and other factors …

Circadian clocks are endogenous time keeping mechanisms that drive near 24-h
behavioural, physiological and metabolic rhythms in organisms. It is thought that organisms …
