This in turn helps to better protect them from their grazers, letting them survive longer to reproduce and therefore compete better within the plankton.". Lingulodinium polyedra: Taxonomy navigation › Lingulodinium. Size: Length and width 42-54 µm. No matter how it works, it appears their ability to ward off predators with bioluminescence serves as a key mechanism behind the success of an otherwise poor competitor such as L. polyedra, the researchers say.

The second is that the flash of bioluminescence behaves like a flash-bang and startles the copepod, provoking a copepod escape response or disorienting it long enough for the dinoflagellate to escape. "That bioluminescence, in addition to being a beautiful light phenomenon in the sea, is a defensive mechanism that some species of plankton use to ward off their enemies," said Andrew Prevett of the University of Gothenburg, Sweden.

"The first is that it acts as aposematic colouration, a warning to potential grazers that the cell is toxic or harmful to the grazer in some way. "This paper and other similar results suggest that indirect predator effects are strong drivers in the microscopic food web of the oceans too.". Two regions of the mRNA were found using an antibody versus luciferase and a cDNA expression library, and the full mRNA was found by Northern hybridization. Wie alle Dinoflagellaten hat Lingulodinium zwei Geißeln, mit denen er sich im Wasser fortbewegt.

Now, researchers reporting in Current Biology on June 17 have found that for one dinoflagellate species (Lingulodinium polyedra), this bioluminescence is also a defense mechanism that helps them ward off the copepod grazers that would like to eat them. This particular bloom stretches from Baja California to Los Angeles, which is especially large. The researchers had expected increased bioluminescence to result in reduced grazing by copepods. April 29, 2020: We are experiencing a red tide, a massive bloom of the dinoflagellate Lingulodinium polyedra, which is a common member of the local plankton community.
