Two serial filters determine P2X7R cation selectivity, Ser342 in the central pore and lateral acidic residues at the cytoplasmic interface

This paper identifies two sequential filters in the P2X7R channel that determine cation selectivity: a dynamic tri-serine-342 size filter and static acidic residues at the cytoplasmic interface.

Mesopredator-mediated trophic cascade can break persistent phytoplankton blooms in coastal waters

The paper shows that mesopredators reduce phytoplankton blooms in coastal waters by promoting microzooplankton grazing, contrasting with freshwater systems where zooplanktivorous fish removal increases blooms.

Desalination and temperature increase will shift seasonal grazing patterns of invasive Gammarus tigrinus on charophytes

This study examines how temperature and salinity changes affect grazing by invasive Gammarus tigrinus on charophytes, predicting shifts in grazing patterns under future climate conditions.

Dynamics of primary productivity in relation to submerged vegetation of a shallow, eutrophic lagoon: a field and mesocosm study

The paper compares primary productivity in mesocosms with macrophytes and phytoplankton-dominated systems to a real lagoon, finding that macrophytes do not re-colonize due to net-heterotrophy.
