Dr. Lucie Aulus-Giacosa

I joined the group in July 2021. I am currently working on the definition of ants and insects’ bioregions. I am interested in how dispersal of alien species redefines biogeographic areas. 


Firstly, I am interested in defining insects’ bioregions and comparing them to the bioregions of other orders (mammals, amphibians, birds, plants …). Secondly, my aim is to determine whether invasions has shaped new bioregions and understand causes and consequences of such changes. 

During my PhD, I worked on the dispersal ability of the Brown trout (Salmo trutta L.) introduced in the Kerguelen Islands. My major aims were to determine causes of facultative migration and understand processes of dispersal in expanding species range, with a focus on spatio-temporal evolution of life-history traits. 

I am now focusing on insects’ dispersal at a more global scale. I aim to understand the changes biogeographic regions and their impact on diversity. In a second phase, I would be interested in developing additional approach to directly model evolutionary processes at the species level.
