Additional file 1 of Community dynamics and functional traits drive microplastic sequestration by marine nematodes

AI summary Read the abstract

Supplementary materials for a study on community dynamics and functional traits driving microplastic sequestration by marine nematodes; full findings are reported in the primary publication. Marine nematodes represent an underappreciated biological pathway through which microplastics enter benthic food webs and sediment ecosystems.

Community dynamics and functional traits drive microplastic sequestration by marine nematodes

AI summary Read the abstract

Researchers ran short- and long-term microcosm experiments to investigate how marine nematode communities interact with microplastics in benthic sediments, finding that meaningful particle sequestration only occurred at very high MP densities and was driven primarily by opportunistic non-selective feeders, while community-level impacts on nematode structure paradoxically appeared most severe at low MP concentrations.

Community dynamics and functional traits drive microplastic sequestration by marine nematodes

AI summary Read the abstract

Researchers used short- and long-term microcosm experiments to show that marine nematode communities sequester microplastics primarily at very high particle densities, with opportunistic non-selective feeders responsible for 90% of short-term uptake, while paradoxically the most severe community disruption occurs at low densities where no particle ingestion is detectable.

Insights into taxonomic and functional trait assessment of marine nematodes in mediterranean coastal ecosystems after exposure to polyethylene microplastics and sulfonamide antibiotics

AI summary Read the abstract

Researchers examined how polyethylene microplastics and sulfonamide antibiotics — individually and combined — affected marine nematode communities from two Mediterranean coastal sites, finding significant reductions in population indices, altered feeding behavior, and changes in life strategy traits, indicating that co-occurring pollutants can restructure bottom-dwelling ecosystems.
