Co-occurrence networks reveal the central role of temperature in structuring the plankton community of the Thau Lagoon

Abstract To identify the environmental factors that drive plankton community composition and structure in coastal waters, a shallow northwestern Mediterranean lagoon was monitored from winter to spring in two contrasting years. The campaign was based on high-frequency recordings of hydrological and...
