Organisms use changes in photoperiod for seasonal reproduction to maximize the survival of their offspring. Birds have sophisticated seasonal mechanisms and are therefore excellent models for studying these phenomena. Birds perceive light via deep-brain photoreceptors and long day-induced thyroid-stimulating hormone (TSH, thyrotropin) in the pars tuberalis of the pituitary gland (PT), which cause local thyroid hormone activation within the mediobasal hypothalamus. The local bioactive thyroid… 
Reproduction in the Eared Dove: An exception to the classic model of seasonal reproduction in birds?
TLDR
The results show that male gonad function is not seasonal in terms of spermatogenesis but that circulating testosterone levels are correlated with photoperiod, demonstrating an exception to the classic model of reproduction in birds.
Effects of Melatonin on Anterior Pituitary Plasticity: A Comparison Between Mammals and Teleosts
TLDR
The known pathways through which melatonin modulates anterior pituitary hormonal production are described, distinguishing indirect effects mediated by brain centers from direct effects on the anterior pituitsary.

TLDR
It is demonstrated that temperature‐dependent modulation of photoperiodic responses manifest in the thyrotrophin‐sensitive tanycytes of the mediobasal hypothalamus, defining a mechanistic hierarchy for the integration of predictive temporal cues and proximate thermo‐energetic effects in mammalian reproduction.
A metabolic coincidence mechanism controls winter photoperiodism in plants
TLDR
This work uses bioinformatics to identify a group of winter photoperiod-induced genes in Arabidopsis and shows that one, PP2-A13, is critical for fitness and survival, exclusively in winter-like Photoperiods.

Gonads or body? Differences in gonadal and somatic photoperiodic growth response in two vole species
TLDR
Development of the neuroendocrine system driving photoperiodic responses in gonadal and somatic growth differ between the common and the tundra vole, indicating that they use a different breeding strategy.

Trans-seasonal activation of the neuroendocrine reproductive axis: Low-temperature winter dormancy modulates gonadotropin-releasing hormone neurons in garter snakes.
TLDR
The data demonstrate that the neuroendocrine GnRH system is sensitive to environmental temperature and suggest that GnRH neurons play a conserved but trans-seasonal role in mediating changes in reproductive physiology and behavior in dissociated breeders.
Photoperiod affects the laying performance of the mountain duck by regulating endocrine hormones and gene expression
TLDR
Results suggest that extended photoperiods may promote the laying performance of ducks by inhibiting the secretion of GnIH and the expression ofgnIHR and melatonin receptor genes.
Telling the Seasons Underground: The Circadian Clock and Ambient Temperature Shape Light Exposure and Photoperiodism in a Subterranean Rodent
TLDR
The results elucidate the interrelationship between the circadian clock and temperature in shaping seasonal light exposure patterns that convey photoperiod information in an extreme photic environment and corroborate that tuco-tuco’s light exposure across the seasons is sufficient forPhotoperiod encoding.
