Climate change is causing warming in the oceans, which can have significant effects on marine food webs. Rising ocean temperatures can intensify seawater stratification, a process in which ocean water forms layers of different densities that mix less readily. This can reduce the supply of nutrients to surface waters and favor smaller phytoplankton species that are better adapted to low-nutrient conditions.

Phytoplankton support zooplankton, which in turn transfer energy to fish and other animals. Changes in phytoplankton communities can therefore lead to cascading effects on marine food webs.

eDNA study reveals drivers of dramatic restructuring of marine food web

A new study from Plymouth Marine Laboratory (PML) has combined decades of microscope records with cutting-edge environmental DNA (eDNA) data to uncover the drivers of a major shift at the base of the marine food web in UK waters. The work is published in the journal Communication
