Photoperiodism in Jute

Nature, 1946

Photorefractoriness in birds—photoperiodic and non-photoperiodic control

General and Comparative Endocrinology, 2007
Avian breeding seasons vary in length and in the degree of asymmetry with respect to the annual cycle in photoperiod to suit species-specific food resources. Asymmetry is the result of photorefractoriness. The degree of photorefractoriness, absolute or relative, is related to the length and asymmetry of the breeding season. Absolute photorefractoriness

Photoperiodism in Neurospora Crassa

Journal of Biological Rhythms, 2004
Plants and animals use day or night length for seasonal control of reproduction and other biological functions. Overwhelming evidence suggests that this photoperiodic mechanism relies on a functional circadian system. Recent progress has defined how flowering time in plants is regulated by photoperiodic control of output pathways, but the underlying ...

Photoperiodism in birds.

Ciba Foundation symposium, 1985
Birds show a circadian rhythm in melatonin secretion and, as expected, the pattern of output changes with photoperiod. Somewhat surprisingly then, in view of the mechanisms in mammals, birds do not seem to use this seasonal message in the photoperiodic control of reproduction.
