Egg mass incubation period: There was a significant difference in egg mass incubation period among the temperature and photoperiod
conditions (A, B and C) (ANOVA: [F.
Sexual dimorphism of the stress response with a normal and altered photoperiod
External cues, like temperature changes and changes to the food supply, become obvious when the photoperiod
changes more drastically.
The plants were transferred to 16-h photoperiod
for 10 to 15 d, and then used as explant source.
4], observed in trout and goldfish, indicate a correlation with feeding and photoperiod
(REDDY; LEATHERLAND, 1994), and also with temperature (ROZIN; MAYER, 1961; CUENCA; GALLEGO, 1987; HIGUERA, 1987; SMITH, 1989).
Animals were taken directly from the field and tested under normal and reversed photoperiods
, as well as in constant dark and light.
1]) under three photoperiods
(24, 12, and 0 h of light).
05) cortisol release in ewes from both the SN and LN photoperiods
starting from the first hour after treatment.
beani adaptation to the range of light intensities and photoperiods
tested under culture conditions as did not show significant differences on growth or survival, similar to species such as Hippocampus whitei, O.
Leptin may play a regulation on body mass and energy metabolism by acting on hypothalamic neuropeptide of NPY expression under different photoperiods
Chickens subjected to a short/non-intermittent photoperiod
had the lowest body weight, body weight gain, feed intake, carcass weight, and fillet and tender weights when compared with those reared under long/continuous and regular/intermittent photoperiods
Endogenous hormones play an important role in regulating the plant development and flowering process under varied photoperiods
