During the initial light-dark cycle experiments, most Pteria penguin juveniles retained their old byssus (>80%) and, during observation, new byssus threads were secreted.
squamosissimus) and zooplankton groups (microfilterers, cladocerans, calanoids and cyclopoids) between the surface and the bottom of the lake, we applied a one-way analysis of variance (one-way ANOVA) to each period of the light-dark cycle, with p < 0.05 considered significant.
In the laboratory, spiders were kept in plastic 750 ml screw cap bottles with a light-dark cycle of 12:12.
(http://www.cell.com/current-biology/fulltext/S0960-9822(16)31522-6) The paper , titled "Circadian Entrainment to the Natural Light-Dark Cycle across Seasons and the Weekend," was based on two studies (one from the summer and the other from winter), was published Wednesday in the journal Current Biology.
"The good news is that we subsequently showed that these negative effects on health are reversible when the environmental light-dark cycle is restored," Meijer says.
The zeitgeber for circadian rhythms is the light-dark cycle (e.g., Forward et al., 1982; Ziegler and Forward, 2005, 2006), while tidal cycles in salinity (Forward et al., 1986) and hydrostatic pressure (Forward and Bourla, 2008) can entrain circatidal rhythms.
It seems that given the chance, our bodies naturally adjust to the light-dark cycle of the rising and setting sun.
* Respect your natural light-dark cycle: exposing yourself to light during the day and sleeping during the night.
Within two weeks of returning to a standard light-dark cycle, the hamsters appeared to have made a full recovery.
The hamsters involved in the experiment were exposed for four weeks to dim light at night - equivalent to a television screen in a darkened room - and the results compared to a control group exposed to a normal light-dark cycle.
This weight gain may be attributed to disruption of the normal light-dark cycle that regulates meal time.
