Alterations induced by global change such as warming, stratification, acidification, eutrofication and deoxygenation are processes that affect marine life, from primary producers to top predators. Species and populations respond to these environmental stressors by changing their distribution (temporal and spatial), phenology (annual migrations), and physiology (development, growth, and reproduction). Reproductive and feeding migrations are also affected by global change.
All these modifications lead to changes in trophic food webs and mismatches in terms of species interactions. Marine life responses also include feedbacks to atmospheric chemistry and climate.
To assess future scenarios, we pursue a better understanding of the interactions among physical, chemical, and biological processes.
