Microplastics and Cadmium Affect Invasion Success by Altering Complementarity and Selective Effects in Native Community

Soil Microplastic Pollution Enhances Plant Invasions by Restructuring Native – Invasive Competitive Interactions

Microplastics and cadmium affect invasion success by altering complementarity and selection effects in native community

AI summary · Read the abstract

Researchers tested how microplastics and cadmium individually and together affect invasive plant success in native plant communities of varying diversity. Microplastics alone reduced invasion success by up to 63% in high-diversity communities, while cadmium increased invasive plant biomass by 40%, but microplastics suppressed this cadmium-driven boost.

Feedback, synergy and antagonism between microplastics and soil organisms

Microplastics, tiny plastic fragments from industrial waste and vehicle exhaust, are building up in soil, and this review pulls together research on how they disrupt soil life, from bacteria to earthworms to crop plants like wheat and tomatoes. The effects are a mixed bag: some microbes actually thrive, while earthworms can suffer toxic effects and plants may absorb harmful chemicals through their roots. This matters because these plastics can accumulate over time and potentially move up the food chain into the foods we eat, though scientists say more research is needed to fully understand the risks.

Pollution and Biological Invasions: Two Synergistic Ecological Disruptors!

AI summary · Read the abstract

Researchers reviewed how chemical pollutants—including microplastics, heavy metals, and pesticides—synergize with biological invasions by weakening native species and altering habitats in ways that favor invasive species, while invasives in turn modify pollutant cycling, creating feedback loops that accelerate ecological degradation beyond what either stressor causes alone.
