Our study showed that the administration of endotoxin induced stress response in animals regardless of the photoperiodic
conditions because the elevated cortisol concentration was determined in blood of all LPS-treated ewes.
Effect of geographical origin on the photoperiodic
control of reproduction in the white-footed mouse, Peromyscus leuopus.
differences are apparent when Cannabis populations obtained from different latitudes are grown together in a northern experimental garden.
control of the development of the LHRH neurosecretory system of European starlings (Sturnus vulgaris) during puberty and the onset of photorefractoriness.
Properties and Neuroendocrine Mechanisms of Photoperiodic

Abolition of the seasonal release of luteinizing hormone and testosterone in Alpine male goats (Capra hircus) by short photoperiodic
Poinsettias are photoperiodic
which means flowering is initiated by a change in day length.
response of the pitcher plant mosquito (Wyeomyia smithii) has shifted toward shorter, more southern day lengths in response to an extended growing season, demonstrating an adaptive evolutionary response to global warming in eastern North America (Bradshaw and Holzapfel 2001).
