Abstract

Advances in ecological stoichiometry, a rapidly expanding research field investigating the elemental composition of organisms and their environment, have shed new light on the impacts of climate change on freshwater and marine ecosystems. Current changes in the Earth's climate alter the availability of carbon and nutrients in lakes and oceans. In particular, atmospheric CO2 concentrations will rise to unprecedented levels by the end of this century, while global warming will enhance stratification of aquatic ecosystems and may thereby diminish the supply of nutrients into the surface layer. These processes enrich phytoplankton with carbon, but suppress nutrient availability. Phytoplankton with a high carbon‐to‐nutrient content provide poor‐quality food for most zooplankton species, which may shift the species composition of zooplankton and higher trophic levels to less nutrient‐demanding species. As a consequence, climate‐driven changes in plankton stoichiometry may alter the structure and functioning of entire aquatic food webs.

Highlights

  • Advances in ecological stoichiometry, a rapidly expanding research field investigating the elemental composition of organisms and their environment, have shed new light on the impacts of climate change on freshwater and marine ecosystems

  • Global warming strengthens the vertical stratification of aquatic ecosystems, which suppresses the supply of nutrients from deep water layers into the surface layer

  • Inspired by Redfield and the recent advances in ecological stoichiometry, this review explores the potential impacts of climate change on the C and nutrient availability in aquatic ecosystems, its consequences for the C:N:P stoichiometry of plankton communities, and its implications for the structure of aquatic food webs

Dedmer B van de Waal, Antonie M Verschoor, Jolanda MH Verspagen, Ellen van Donk, and Jef Huisman1*. A rapidly expanding research field investigating the elemental composition of organisms and their environment, have shed new light on the impacts of climate change on freshwater and marine ecosystems. Atmospheric CO2 concentrations will rise to unprecedented levels by the end of this century, while global warming will enhance stratification of aquatic ecosystems and may thereby diminish the supply of nutrients into the surface layer. These processes enrich phytoplankton with carbon, but suppress nutrient availability.
