Lewis, "
Photoperiodism and seasonal cycles of development," Insect Clocks, pp.
Statistical research has documented seasonal patterns described in terms of sociological and biological factors such as the variations of the circadian biological clock and
photoperiodism, variety in terms of neurotransmitters, a.s.o.
Cannabis sativa is an annual plant, growing vegetatively in the early part of its life cycle, and induced to flower by photoperiod, the timing of induction being one of many adaptive features of the plant, discussed in this review (in the "Evolution of
Photoperiodism Under Domestication" section).
Specific topics covered include insect-insect and insect-plant interactions, insect biotechnology for pest control, insect
photoperiodism and many more.
Study of
photoperiodism on gonadal weight in a Readhead bunting under natural day length [Ndl].
Extraretinal photoreception in entrainment and
photoperiodism in invertebrates.
Note, however, that flowering, bulb development and pre-dormancy preparation are controlled by length of day (
photoperiodism).
Among the topics are lessons on circadian clocks from fish, an update of the morning and evening oscillator model in Drosophila, dynamic neuronal network organization of the circadian clock and possible deterioration in disease, circadian modulation of sleep in rodents, local aspects of sleep revealed by observations from intra-cerebral recordings in humans, feedback actions of locomotor activity to the circadian clock, managing neurobehavior capability when social expediency trumps biological imperatives, the evolutionary physiology of
photoperiodism in vertebrates, and circannual rhythm in the varied carpet beetle Anthrenus verbasci.
They are growing their winter fur based on
photoperiodism, not temperature.
Genetic variation in
photoperiodism among naturally photoperiodic rat strains.
