Abstract

Microscopic plastic debris, termed “microplastics”, are of increasing environmental concern. Recent studies have demonstrated that a range of zooplankton, including copepods, can ingest microplastics. Copepods are a globally abundant class of zooplankton that form a key trophic link between primary producers and higher trophic marine organisms. Here we demonstrate that ingestion of microplastics can significantly alter the feeding capacity of the pelagic copepod Calanus helgolandicus. Exposed to 20 μm polystyrene beads (75 microplastics mL(–1)) and cultured algae ([250 μg C L(–1)) for 24 h, C. helgolandicus ingested 11% fewer algal cells (P = 0.33) and 40% less carbon biomass (P < 0.01). There was a net downward shift in the mean size of algal prey consumed (P < 0.001), with a 3.6 fold increase in ingestion rate for the smallest size class of algal prey (11.6–12.6 μm), suggestive of postcapture or postingestion rejection. Prolonged exposure to polystyrene microplastics significantly decreased reproductive output, but there were no significant differences in egg production rates, respiration or survival. We constructed a conceptual energetic (carbon) budget showing that microplastic-exposed copepods suffer energetic depletion over time. We conclude that microplastics impede feeding in copepods, which over time could lead to sustained reductions in ingested carbon biomass.

  • Irrespective of the exposure concentration, the percent MP ingestion quantified here, and in previous studies, is extremely low (i.e., <1%).

    “Yet, irrespective of the exposure concentration, the percent MP ingestion quantified here, and in previous studies (Cole et al., 2015; Procter et al., 2019), is extremely low (i.e., &lt; 1 %).”

    From Trophic transfer of polyester microfibres across a multi-level marine food web. (2025) · cites this paper as Cole et al., 2015

    The Treatments section (page unavailable) reports 3,278 polystyrene beads and 45,700 algal cells ingested per copepod per day. On a share-of-ingested-particles basis, the beads account for about 6.7%, not less than 1%. The paper tested one microplastic concentration, so it also cannot establish the claim across exposure concentrations. (LLM, conf=0.82)

  • PS MPs decrease survival and fecundity of Calanus helgolandicus.

    “Studies of small crustaceans include those by Cole et al. (2015) and Lee et al. (2013) who observed a decrease in survival and fecundity of the marine copepods Calanus helgolandicus (24 h and 216 h; 20 μm; 6.5-7.5 × 10 4 particles L -1 )”

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.
