Fourth Annual Traits Workshop

Reporting by Helen Hill for the MIT Darwin Project

The fourth Workshop on Trait-Based Approaches to Ocean Life, held August 18-21, 2019 at Chicheley Hall in Buckinghamshire in the UK was a wonderful opportunity for Darwin Group members to catch up with former colleagues while sharing current directions in marine ecology viewed through a traits lens.

Phytoplankton & Chips

Helen Hill | Darwin Project

Microbes mediate the global marine cycles of elements, modulating atmospheric CO2 and helping to maintain the oxygen we all breath yet there is much about them scientists still don’t understand. Now, an award from the Simons Foundation will give researchers from the Darwin Project access to bigger, better computing resources to model these communities and probe how they work.

Darwin goes to Ocean Sciences 2014

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.
