The core objective of the research team deals with adaptive responses of the organism to environmental factors, with a central focus on functional and evolutionary aspects. The conducted researches, using different models (plants, arthropods, birds, mammals) are mainly based on experimental and pluridisciplinary approaches, associating data from behavioural ecology, functional anatomy and integrative physiology. The common aim is to decrypt among environmental factors, either abiotic (climate, light, habitat, food resources) or biotic (interindividual communication, social systems), those representing the major selective constraints in the expression and regulation of adaptive responses. In this context, perception of the environment, that is sensory pathways and signals, represents a key feature to understand the mechanisms underlying the regulation of adaptive responses. Among those mechanisms, daily and seasonal rhythms are of main interest owing to their high adaptive value to recurrent variation of the environment. Finally, adaptations are the result of evolutionary processes to face pressure of selection. Therefore, part of our research aims at bringing pieces of explanation to processes of phylogeny, and even speciation. These researches are most often developed in collaboration with other scientific teams and are funded by several research grants. They rely on the concepts of behavioural ecology and more generally to the biology of adaptation. They bring new pieces of thought about the set up of protocols of biodiversity management, and even provide applications in the field of human health.
