Effect of polyethylene microplastics on the overwintering and nesting behaviour of the common field ant, Lasius neoniger dataset
AI summary Read the abstract
This dataset documents the effects of polyethylene microplastic exposure on the overwintering and nesting behavior of the common field ant Lasius neoniger. The laboratory trials on whole colonies investigated how microplastic contamination in soil affects ant behavior and mortality during critical life stages.
Dataset related to the effects of microplastic exposure on Lasius neoniger overwintering and nesting behaviour of the common field ant, Lasius neoniger (Emery) (Hymenoptera: Formicidae). This research investigates the impact of polyethylene microplastics on Lasius neoniger behaviour and mortality during overwintering and nesting. These trials were conducted under laboratory conditions on whole colonies of Lasius neoniger.

Individual vs. Combined Short-Term Effects of Soil Pollutants on Colony Founding in a Common Ant Species
AI summary Read the abstract
Individual and combined exposure of ant colonies to soil pollutants -- including microplastics -- during colony founding phase showed that combined exposures had non-additive effects on colony establishment success, with implications for understanding how pollutant mixtures contribute to insect decline.
The transport of microplastics by ants cannot be neglected in the soil ecosystem
AI summary Read the abstract
Laboratory experiments demonstrated that ants can actively transport low-density polyethylene microplastics through soil, carrying particles both into their nests and across soil layers at rates that could meaningfully affect microplastic distribution at the ecosystem scale. The findings identify soil fauna as an underappreciated biotic driver of microplastic vertical and horizontal migration in soils.
Ants actively carry microplastics
AI summary Read the abstract
This study found that ants actively transport microplastic particles, carrying them both into and out of their nests, making them a previously overlooked pathway for microplastic movement in soils. Soil invertebrates may play a significant role in spreading microplastic contamination through terrestrial ecosystems.
Microplastics lead to behavioral disorders in soil nematode movement, foraging and food choice
AI summary Read the abstract
Researchers investigated the effects of low-density polyethylene and biodegradable poly(lactic acid) blend microplastics on movement, foraging, and food choice behaviors of four soil nematode species in a soil-based modular test system, finding behavioral disorders that differed from agar plate assay results.
Sublethal effects of microplastics sourced from polypropylene agricultural plastics on four soil invertebrate species
AI summary Read the abstract
Four soil invertebrate species were exposed to microplastics from polypropylene agricultural mulch at 0.005–5% concentrations in soil, finding reduced reproduction in enchytraeids and collembola and altered burrowing behavior in earthworms and isopods at higher doses.
