Reproductive Competition and Sociality
(Seasonal unpredictability and social flexibility)

Dernière mise à jour : lundi 17 juin 2019, par Catherine Berger

We are looking for a highly motivated postdoc who will apply with us for a fellowship to study the influence of the degree of reproductive competition on sociality.

For this, a long-term dataset on social organisation of striped mice will be used and extended (years 2003 until 2021). Sociality (% of solitary versus group-living striped mice) will be studied depending on population density and the intensity of reproductive competition, which is (i) very high during the spring breeding season when all females breed, (ii) absent during most summer dry seasons, (iii) low during summers with unexpected rains when few females breed (6 out of 17 summers in the current data set).

Key requirements :
Strong statistical skills. Good understanding of social evolution. Strong CV, with 3 publications from the PhD and at least two publications per year of postdoc, some of them in high ranking journals (impact factor >3). Willingness to spend considerable time in the field in South Africa.

What you will learn :
Strong field skills. The postdoc will spend considerable time in the field. It is expected that the postdoc will prepare and start analysing the database while being based at the Succulent Karoo Research Station in South Africa.
