Leaving the cold of a New England February behind, the Darwin team will be in full attendance at this year’s Ocean Sciences conference taking place February 23-28 in Honolulu, Hawaii.

Size Structure: exploring nutrient versus grazing control
Idealized equilibrium models have attributed the observed size structure of marine communities to the interactions between nutrient and grazing control. In a new paper in the Journal of Plankton Research Ben Ward and co-authors Stephanie Dutkiewicz and Mick Follows examine this theory in a more realistic context using a size-structured global ocean food-web model, together with a much simplified version of the same model for which equilibrium solutions are readily obtained.

Winners and losers in a warming ocean

Phytoplankton — small plant-like organisms that serve as the base of the marine ecosystem — play a crucial role in maintaining the health of our oceans by consuming carbon dioxide and fueling the food web. But with a changing climate, which of these vital organisms will survive, and what impact will their demise have on fish higher up the chain?
Stephanie Dutkiewicz, a researcher with the MIT Joint Program on the Science and Policy of Global Change, and her colleagues developed a model that investigates the potential effects of climate change on phytoplankton.
