Impacts of aerosols on aquatic and terrestrial ecosystems

Session ID#: 78901

Session Description:
Aerosols are derived from both anthropogenic and biogenic sources. It is known for decades that atmospheric aerosol deposition may significantly affect the structure and function of aquatic and terrestrial ecosystems. For example, aerosol deposition represents a supply of nutrients (e.g. N, P, S, Fe…) to diverse components of ecosystems such as plankton, plants, and microbes which can further impact other functional and structural aspects at larger scales. However, there are still many open questions to be answered to elucidate the mechanistic understanding of the impacts of aerosol deposition on ecosystems. Recent analytical and bioinformatic methods provide unprecedented tools permitting accurate investigation of atmosphere-biosphere interactions ranging from the chemical mechanisms to global models. This session invites abstracts from field, laboratory, and modeling studies that investigate the impacts of aerosols on ecosystems. Submissions on related conceptual or theoretical framework, and feedbacks of aerosol fluxes on ecosystems are also welcome.
