Diatoms are one of the most diverse groups of phytoplankton in the ocean. One reason for this high diversity is the evolution of multiple defence mechanisms and subsequent evolution of grazer “counter measures”. In a new study, we describe the discovery of yet another defence mechanism: when exposed to chemical cues from copepods several...
Phytoplankton employ a wide variety of defense against grazers, and rely on chemical cues to assess the current grazing pressure. However, these signals are potentially vulnerable to environmental change, such as ocean acidification. In a collaboration with the Marine Chemical Ecology group at the University of Gothenburg, Sweden, Ocean...
The diatom frustule has been shown to provide protection against grazing copepods, but the mechanisms behind the defense is unknown. In a new paper published in Limnology and Oceanography Letters, we directly observe copepod-diatom interactions and provide a mechanistic understanding of the defense: not only are diatoms with thicker shells...
Several PhD students represented the Centre for Ocean Life at this year's ASLO conference.
Diatoms live in a protective silica shell. A new study demonstrates that diatoms increase the thickness of the shell in the presence of their copepod predators but at the cost of a lower growth rate.
A new Ocean Life paper shows that overwintering of the copepod Calanus hyperboreus contributes significantly to the sequestration of carbon. We propose a general method, based on metabolic theory, as to how a global inventory can be built for observation-poor species in other parts of the world’s oceans.
