Kind: research · Impact: medium

## In brief

- A study from Plymouth Marine Laboratory combined decades of microscope records with environmental DNA (eDNA) data.
- The work examines a major shift at the base of the marine food web in UK waters.
- The study aims to identify the drivers behind this restructuring.

## Why it matters

Changes at the base of the marine food web can affect the wider ecosystem, so identifying their drivers helps researchers interpret long-term marine monitoring data.
