Clear benefits without direct costs in dinoflagellate defenses

Many dinoflagellates produce toxins in response to grazers, but costs have been hard to establish experimentally. A new Ocean Life paper examines the effect of nutrient...

Foraging trade-offs in flagellates: To eat and not be eaten – that is the (impossible...

In most organisms foraging implies elevated exposure to predators. Such foraging trade-offs are universal and are main determinants of the structure and function of ecosystems...

Feeding flows of microorganisms attached to solid surfaces

Many aquatic microorganisms attach to solid surfaces while creating feeding flows that bring prey particles to them. A new paper in Physical Review Fluids explores how...

PhD scholarship in Fluid dynamics, evolution, and ecology of flagellate foraging

The Centre for Ocean Life at DTU Aqua, Technical University of Denmark, offers a PhD scholarship in ‘Fluid dynamics, evolution, and ecology of flagellate foraging...

Sponge pumps and evolution of the sponge body plan

Pumping units in most sponges possess a gasket structure ensuring efficient pumping and filtration. However, some sponges lack such structure in their pumping units and...

Tethered flagellates

To tether or not to tether

Many or most flagellates are tethered to particles when feeding, and it is generally accepted that attachment allows organisms to enhance their feeding flow. This view...

A general size- and trait-based model of plankton communities

Most models of plankton communities, such as NPZ-type models, ignore the life-cycle (ontogeny) of multicellular zooplankton. Here, we propose a model framework along the...

Size-based theory for fisheries advice

Today’s advice for fisheries management uses the venerable “Beverton-Holt” theory of fish demography. The theory describes the abundance of fish of different...

How are marine organisms adapted to seasonality?

One of the most conspicuous features over much of the world’s oceans is the seasonal variation in environmental conditions (e.g. light, temperature, nutrients, food...
