Procreation is essential for survival of species. Not surprisingly, complex neuronal networks
have evolved to mediate the diverse internal and external environmental inputs that regulate …

Photoperiodism is the ability of plants and animals to measure environmental day length to
ascertain time of year. Central to the evolution of photoperiodism in animals is the adaptive …

Kisspeptin‐GPR54 signalling is essential for normal reproductive functioning. However, the
distribution of kisspeptin neuronal cell bodies and their projections is not well established …

Synchronization of mammalian breeding activity to the annual change of photoperiod and
environmental conditions is of the utmost importance for individual survival and species …

Kisspeptin is an important regulator of reproduction in many vertebrates. The involvement of
the two kisspeptins, Kiss1 and Kiss2, and their receptors, Gpr54-1 and Gpr54-2, in …

In mammals, melatonin is the pivotal messenger synchronizing biological functions, notably
reproductive activity, with annual daylength changes. Recently, two major findings clarified …

Reproduction, like many other biological functions, exhibits marked daily and seasonal
rhythms in order to anticipate and adapt breeding activity to environmental challenges. In …

In seasonal breeders, reproduction is synchronized to seasons by day length via the pineal
hormone melatonin. Recently, we have demonstrated that Kiss1, a key activator of the …

Seasonal reproduction is a common adaptive strategy among mammals that allows for
breeding to occur at times of the year when it is most advantageous for the subsequent …

The discovery that kisspeptin was critical for normal fertility in humans ushered in a new
chapter in our understanding of the control of GnRH secretion. In this paper, we will review …
