Today, a new paper by Santiago Hernández-León about the functioning of the pelagic ecosystem. The author poses a hypothesis about the role of large predators on the structure of the pelagic food web. Diel vertical migrants promote a predatory pressure over zooplankton. This predation is driven by lunar illumination and therefore is cyclic. The presence or not of mesozooplankton also promotes a cascade effect down food web. Two different scenarios could be observed depending on the presence or not of mesozooplankton. What are the consequences of this top-down effect for the carbon flux? Do not miss this interesting paper. You can find it in your nearest library.
