Research Interests

My PhD project is about the relationship between individual behavioural differences and the social environment in Neolamprologus pulcher.

This species is a cooperatively breeding fish that lives in stable groups of related and unrelated individulas. Dominant individuals monopolize reproduction, and subordinates help defending the territory and caring for the offspring, while trying to gain dominance themselves. This stable social system is well suited to study personality development and the role of individual behavior in life history decisions.

My work is focused on the relationship between social roles and individual behavior, defined as behavioural patterns that are unique to an individual and consistently different to the behavior of others.

1) Testing the social niche hypothesis (Bergmuller Taborsky 2010)
I aim at empirically testing whether the experience of a specific social environment during ontogeny can affect the behavioural development of individuals, and create different behavioural types.

2) Individual behavioural types and social decisions
I investigate how the behavioural type of group members can influence acceptance of new individuals in a group, or mate choice and pair performance (with Master student Mattia Maldonado).
