Projects

My research lies in the field of evolutionary ecology and behavioural ecology with close ties to biology and population dynamics. My study model is the Alpine marmot, which I have studied since 1990 in a nature reserve managed by the Vanoise National Park. Working in a protected environment, my approach is essentially correlative.

The questions I pose cover several topics:

1. Evolutionary causes of monogamy

Monogamy is a relatively rare mating system in mammals, who are more likely polygynous. The formation of a couple is central to the concept of monogamy and I am interested in the processes of mate choice. I want to know if females choose their partner based on absolute genetic characteristics (genetic quality) or relative genetic characteristics (genetic compatibility) and also whether this choice concern the entire genome or certain key loci as the Major Histocompatibility Complex (MHC). I consider both the choice of social partner (the individual with whom the female forms a pair) as well as the choice of sexual partner (which may be different from the social partner). I am also interested in the mechanisms of choice: how females recognise a male of good genetic quality or a male presenting adequate genetic compatibility. For this, the role of smell is central. Finally, I am interested in the consequences of choice (particularly demographic) on the performance of offspring.

2. Evolutionary causes of sociality

To understand the evolution of sociality, I am interested in the costs and benefits of living in social groups. The biological model is the Alpine marmot who lives in family groups consisting of a dominant couple who monopolize (or attempt to monopolize) reproduction, sexually mature subordinate individuals (generally descendants of the dominant pair) who delay their dispersion and do not reproduce, yearlings and the pups of that year. I am currently studying the influence of the size and composition of groups (age, sex and parental relationship) on the reproductive success of dominants. I seek to quantify the cost to the dominants of reproductive competition between dominants and subordinates of the same sex. Meanwhile, I am analysing how the presence of subordinates benefits the reproductive success of dominants.

3. Life history traits and climate change

Several studies have shown the influence of climate change on species’ distribution and sought to predict future distributions of species in response to these changes. However, it is important to understand how, by which mechanisms, climate change is affecting populations. Extreme environments, such as mountain environments or polar environments, are very sensitive to these changes. I research the effects of climate change on individuals’ demographic performance (litter size, survival) but also on other life history traits (weight, size and composition of social groups) which may indirectly affect individual performance. The biological model is the Alpine marmot in the Grande Sassière valley.
