Glucocorticoids (GCs) are thought to impact reproductive success, and ultimately fitness. In
this study we focus specifically on the relationship between GCs and parental care. Captive …

Mothers have a crucial influence on offspring development. Variations of maternal behaviour
can be due to numerous parameters, for instance costs are related to the size of a …

Individuals within a population often vary in the range and kind of behaviors that they exhibit.
This variation, when consistent across time and/or context, has been termed animal …

Beyond the genetic links between mother and young, prenatal effects experienced by
offspring can modulate their mother's behaviour and stress. Here we investigated the …

Maternal behavior is known to influence the behavioral development of young. Recently, it
was demonstrated that maternal behavior also differed according to sex of chicks and brood …

Sex is a trait which leads mothers to invest asymmetrically in their young, especially in
species with a strong dimorphism. Authors usually consider that members of the largest sex …

The neural system underlying maternal caregiving has often been studied using laboratory
rodents and a few other mammalian species. This research shows that the medial preoptic …
