TL;DR: It can be suggested that testicular thyroid hormone status is being regulated by photoperiod and is possibly involved in seasonal adaptation to reproductive phenomenon of golden hamster.

TL;DR: Evidence of intrapinealocyte lipid droplets and dense bodies and a moderate amount of melatonin in plasma during different reproductive phases finally proved a defined secretory activity of the gland in this tropical, nocturnal bird.

TL;DR: Melatonin could be a major hormone imparting a time-of-day effect on the modulation of immune function in a seasonally breeding bird during the reproductively active phase of Perdicula asiatica.

TL;DR: High metabolic and immune parameters were noted during winter and monsoon which suggest an adaptive significance in tropical goats against ecological stress induced by low temperature of winter and pathogenic invasion occurring while grazing during monsoon.

TL;DR: The results suggest that for reduction of seasonal oxidative stress melatonin might not be utilizing the nuclear receptor RORα pathway; rather the rise in circulatory melatonin collectively with tissue specificmelatonin might be protecting the splenic and thymic lymphocytes from the seasonal oxidative Stress.
