Trophic interactions of fish communities at midwater depths enhance long-term carbon storage and benthic production on continental slopes
Biological transfer of nutrients and materials between linked ecosystems influences global carbon budgets and ecosystem structure and function. Identifying the organisms or functional groups that are responsible for nutrient transfer, and quantifying their influence on ecosystem structure and carbon...

Biological transfer of nutrients and materials between linked ecosystems influences global carbon budgets and ecosystem structure and function.
