Marine #phytoplankton need move up/down in the #ocean to access light & nutrients. Study of the effects of nutrient availability in 9 species reveals that phytoplankton have evolved multiple mechanisms that impact gravitational sinking in response to starvation @plosbiology.org 🧪 plos.io/4iaJFoV
Left: Changes in cell density and cell volume when comparing high nutrient condition (base of each arrow) to indicated starvation conditions (tip of each arrow). Gravitational sinking velocities are indicated in color-coded background. Top right: A transmission electron microscopy image of Tetraselmis sp., a green alga, reveals the internal organization and composition of the cell, as seen under high-growth conditions. Bottom right: A scanning electron microscopy image of Tetraselmis sp., portraying the sinking of the cell following starvation. Image credits: Teemu P. Miettinen, Margaret Bisher, Abigail K. R.
