Social life is a widespread phenomenon in nature that is commonly considered as one of the major evolutionary transitions of life on Earth. Across taxa and species, social life exhibits different degrees of complexity, ranging from short-term to permanent social interactions, and from mutual attraction between individuals to cohesive societies with reproductive division of labor.The ecological success of group living species is commonly attributed to the important benefits each form of social life provides to the individuals, such as higher efficiency in brood survival, foraging strategies and anti-predator defenses. However, group-living also entails major fitness costs. Such costs typically result from (1) social conflicts between group members over food resources and reproduction, and from (2) highest risks of pathogen infection, as frequent and intimate contacts between individuals are known to facilitate disease transmission and because the close genetic relatedness generally exhibited by group members is likely to make them susceptible to the same pathogens. Hence, the transition from solitary to social life requires the evolution of mechanisms ensuring that the benefits of group living outweigh its associated costs.
My research aims at better understanding the emergence and persistence of social life in insects by studying (1) the behavioral processes regulating within-group conflicts, (2) how (social) immunity promotes the emergence and persistence of group-living, (3) the bases of recognition systems and chemical communication within and between groups, and finally (4) the reciprocal interactions between social/ecological environments and life-history traits expressed by group members.
My main biological model is the European earwig, Forficula auricularia. This insect species is particularly interesting to study the early evolution of social life because adults live in groups in which they show advanced forms of interactions and females provide non-obligatory forms of care to their offspring. The methods I use mainly involve behavioral experiments, immunity measurements, chemical and microsatellites analyses, Statistics (Meta-analyses), Field and laboratory experiments.
