The environment in which an animal lives affects the physiology and psychology of that
animal. The greater the distance from the equator the more profound this influence …

Although it is axiomatic that males and females differ in relation to many aspects of
reproduction related to physiology, morphology and behaviour, relatively little is known …

Seasonal reproduction is common among mammals at all latitudes, even in the deep tropics.
This paper (i) discusses the neuroendocrine pathways via which foraging conditions and …

Neurons that produce gonadotropin-releasing hormone (GnRH) drive the reproductive axis,
but the molecular and cellular mechanisms by which hormonal and environmental signals …

Most organisms modulate their reproductive activity responding to day length by the
nocturnal release of melatonin by the pineal gland. This hormone is also responsible for …

The mouse is the most important mammalian model in life science research and the
behavior of the mouse is a key read-out of experimental interventions and genetic …

Melatonin is part of the evolutionary conserved highly functional network in vertebrates. It
plays a central role in the adaptative behavior of the animal to the environment, including …

Seasonal reproduction is common in mammals. Whereas specific conditions triggering a
seasonal response can only be identified in controlled experiments, large-scale …

Appropriate timing of breeding is an important component of reproductive success for almost
all animals world-wide that live in seasonally fluctuating environments. A precise temporal …

In fluctuating environments, matching breeding timing to periods of high resource availability
is crucial for the fitness of many vertebrate species, and may have major consequences on …
