Figures

Fig. 1 DMS concentration in plastic debris headspace. (A) DMS was not detected on any of the virgin plastic samples tested (n = 10 samples each for HDPE, LDPE, and PP, N = 30 total). (B) DMS was detected on every plastic sample after marine exposure (n = 12 bags of each plastic type; each bag subsampled five times). Box plots illustrate DMS concentrations on marine-seasoned plastic of each plastic type across sites (HPDE = 8.31 ± 2.25 μg of DMS per gram of plastic; LDPE = 8.90 ± 1.34 μg of DMS per gram of plastic; PP = 9.56 ± 2.33 μg of DMS per gram of plastic). Points represent each bag’s average DMS quantification; the error bars represent the SE of the five subsamples of each bag. Site averages by plastic type are as follows: for BML, x̄HDPE = 13.45 ± 2.41 μg g−1, x̄LDPE = 11.76 ± 1.65 μg g−1, and x̄PP = 4.99 ± 0.98 μg g−1; for HMS, x̄HDPE = 3.16 ± 1.07 μg g−1, x̄LDPE = 6.05 ± 1.39 μg g−1, and x̄PP = 14.13 ± 2.33 μg g−1.

Fig. 2 Effects of DMS responsiveness and nesting behavior on plastic ingestion in procellariiform seabirds. (A) Maximum likelihood estimate (±SEM) of the DMS-responsive and non–DMS-responsive species groups, illustrating a significantly higher frequency of plastic debris ingestion in DMS-responsive species (binomial GLMM, P < 0.0001). (B) Maximum likelihood estimate (±SEM) of burrow- and surface-nesting species groups, illustrating a significantly higher frequency of plastic ingestion in burrow-nesting species (binomial GLMM, P < 0.05). Burrow-nesting behavior is used here as a proxy for DMS responsiveness.

Fig. 3 Plastic ingestion and DMS responsiveness among procellariiform seabirds. Colored circles and horizontal lines represent the mean and 95% CIs for each species’ model-predicted plastic ingestion prevalence. Vertical dashed lines are model-predicted mean plastic ingestion frequency for each group (DMS-responsive and non–DMS-responsive). Vertical dotted lines represent the 95% CIs of the plastic ingestion frequency for each group.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
