Eddie Pérochon

I joined the group in July 2022. During my PhD, I am investigating the role of environmental factors in shaping the variation and plasticity of social organization in ant species.

I have been interested in arthropods for a long time and I took part to research about several taxonomic groups during my academic cursus (coprophagous beetles, aquatic macroinvertebrates, longwing & clearwing butterflies and ants). I am particularly focusing on species distributions, traits diversity and on large scale interactions between species.

For my PhD project, I am interested in the drivers of ant social organization and traits (i.e. number of workers, number of queens or number of worker casts). I am studying their diversity, variation and plasticity among ants species related to environmental conditions and climatic niches. To achieve that, I study ant species at two levels:

  • Global : I use macroecological approaches to access social structure diversity at a global scale in order to identify geographic and environmental determinants of social traits globally.
  • Local : I study distributions of ants along environmental gradients and I investigate if their social trait variations are related with external conditions and if there is tradeoffs between individual and social functional traits.
