"In a warming world, species may buffer to some extent part of the environmental changes by exploiting the microclimates that are available across space and time. My presentation will focus on the role of the leaf surface microclimate, and in particular temperature, in driving then vulnerability of insects to climate change. I will exemplify the framework we apply to investigate this role. Our approach is deeply rooted into a multidisciplinary background, relying on physics, physiology and ecology of both plant and animal sciences. The microclimatic effects can be quite subtle and mechanistic approaches are fundamentally needed to depict the complexity of the interaction between plant, insect and climate."
