Summary: Pelagic symbioses: teasing apart phytoplankton-bacteria relationships. This project aims to decode the intricate relationships between populations of phytoplankton and marine bacteria and interpret their influence on ocean productivity and chemical cycling. While oceanographers typically consider the ecology of phytoplankton and bacteria in isolation, this project suggests that the lives of these organisms are inherently entwined in symbiosis. This project is anticipated to aid in management of Australia’s valuable marine estate and the ecosystem services and food security it provides.
