Reconstructing marine productivity of the Cariaco Basin during marine isotope stages 3 and 4 using organic-walled dinoflagellate cysts

Differences in the chemical composition of organic-walled dinoflagellate resting cysts from phototrophic and heterotrophic dinoflagellates.

Dinoflagellates constitute a large proportion of the planktonic biomass from marine to freshwater environments. Some species produce a preservable organic-walled resting cyst (dinocyst) during the sexual phase of their life cycle that is an important link between the organisms, the environment in which their parent motile theca grew, and the sedimentary record. Despite their abundance and wides...

3 Testing for resistance of pelagic marine copepods 4 to a toxic dinoflagellate 5 SEAN

11 Abstract. With few exceptions, the evolutionary consequences of harmful algae to grazers in 12 aquatic systems remain unexplored. To examine both the ecological and evolutionary consequences 13 of harmful algae on marine zooplankton, we used a two-fold approach. In the first approach, we 14 examined the life history responses of two geographically separate Acartia hudsonica (Copepoda: 15 Cal...

Meridional reorganizations of marine and terrestrial productivity during Heinrich events

[1] To study the response of the global carbon cycle to a weakening of the Atlantic Meridional Overturning Circulation (AMOC), a series of freshwater perturbation experiments is conducted both under preindustrial and glacial conditions using the earth system model of intermediate complexity LOVECLIM. A shutdown of the AMOC leads to substantial cooling of the North Atlantic, a weak warming of th...
