Comparative physiology of adaptation to cold-extremes in boreal ants

The acquisition of cold-tolerance is one of the most ecologically relevant processes for ectotherms inhabiting temperate and boreal climates. Given the fundamental importance of cold-adaptation in shaping ectothermic species’ distribution, much effort has been put into deciphering the physiological mechanisms constraining the plasticity of their cold-tolerance. However, we still know little about how evolutionary pressures have shaped cold-tolerance acquisition in some key and ecologically relevant models for colder-ecosystems such as ants. Ants are among the most represented and abundant insects in temperate and boreal climates, providing unprecedented amounts of ecosystem services by their sheer biomass. Some higher-latitude species further display the striking ability to survive prolonged exposure to temperatures of -40°C, yet, to this day we still lack a clear and comprehensive understanding of the molecular mechanisms supporting this impressive feat. Considering this central gap in our knowledge, we propose here to explore the molecular-level mechanisms associated with the temporal acquisition of cold-tolerance in ants inside a consistent study system made of groups of boreal, temperate, and Mediterranean closely related species. Using this phylogenetic framework, we will (i) compare species’ potential for cold-hardiness and link cold-tolerance acquisition with the (ii) genetic response and (iii) metabolomic reorganization in models. Overall, this project proposes to explore important yet unanswered aspects of insect cryobiology that are located at the frontier of our current understanding of ecophysiology. It will explore the comparative physiology of cold-acclimation in boreal ants, allow for the potential discovery of novel cold-tolerance mechanisms in insects, and ultimately, feed data into our integrated understanding of how from gene to organisms, the acquisition of cold-tolerance has shaped the success of insect life in colder environments. ver más
