Early social experience influences the development of stereotypic behaviour in captive-born striped mice Rhabdomys
The early life experience of captive animals, in combination with their genetic inheritance, can predispose or promote the development of stereotypic behaviour in later life. To investigate the early social effects of weaning age and the presence/absence of the father on the development of stereotypic behaviour in adulthood, we retrospectively analysed data from our captive […]
Hormones and paternal behavior in vertebrates
This review examines the influence of hormonal stimulation on paternal care in selected species of fish, birds and mammals. Correlational studies of hormonal changes and the occurrence of paternal behavior as well as experimental studies are considered. Understanding the influence of hormones on paternal behavior is complicated by whether the species studied shows maternal, paternal […]
Behavioural and hormonal stress responses during chick rearing do not predict brood desertion by female in a small Arctic seabird
We examined behavioural and hormonal stress responses in a small seabird (little auk, Alle alle), which exhibits a transition from biparental to male-only care towards the end of the nesting period, in order to understand the mechanisms underlying this parental strategy. We hypothesized that the male staying with the chick should be less sensitive to […]
Early rearing experience is associated with vasopressin immunoreactivity but not reactivity to an acute non-social stressor in the prairie vole
The early life experiences of an organism have the potential to alter its developmental trajectories. Perhaps one of the most powerful influences during this period is the parent–offspring relationship. Previous work in several mammalian species has demonstrated that parental care in early life and specifically maternal behavior can influence several adult outcomes in offspring, including […]
Age and sex-specific mortality of wild and captive populations of a monogamous pair-bonded primate (Aotus azarae)
In polygynous primates, a greater reproductive variance in males have been linked to their reduced life expectancy relative to females. The mortality patterns of monogamous pair-bonded primates, however, are less clear. We analyzed the sex differences in mortality within wild (NMales = 70, NFemales = 73) and captive (NMales = 25, NFemales = 29) populations of Azara’s owl monkeys (Aotus azarae), a socially […]
