Microplastic accumulation and trophic transfer in a benthic predator–prey system

Where were the specimens sampled?

Tap a station marker for coordinates and sampling depth. The map uses the recorded coordinates in the supplied dataset.

1 · Microplastic load across the three sites

Individual observations are shown with station-level distributions. Use the filters above to isolate a species or station.

2 · Does body size influence microplastic accumulation?

Each point represents one individual. The fitted line is calculated from the currently selected observations.

3 · Predator–prey transfer: biodilution or bioaccumulation?

BMF = median MP concentration in Rapana ÷ median MP concentration in Mytilus, calculated separately for each station.

4 · What size are the microplastics?

Particle-size composition is calculated from the MP-size columns supplied in the spreadsheet.

5 · What polymers were identified by FTIR?

Polymer composition from the dual Nile Red–micro-FTIR validation subset: 18 samples per species. The polymer data are independent of the 300-individual spreadsheet and are shown here as reported.

6 · Body size across stations

Explore the biometric measurements contained in the dataset. This section is descriptive; the statistical tests should be reported separately on the poster.

7 · Microplastic shape composition

Shapes were automatically categorised by the software based on a circularity index ranging from 0.0 to 1.0, sorting particles into fibres (0.0–0.3), fragments (0.3–0.6), or particles (0.6–1.0).
