Do microplastics and climate change negatively affect shredder invertebrates from an amazon stream? An ecosystem functioning perspective
AI summary Read the abstract
Researchers experimentally tested the combined effects of microplastic pollution and climate change conditions on the survival and feeding behavior of an Amazonian freshwater shredder invertebrate. The study suggests that the combination of microplastic exposure with increased temperature and CO2 levels can negatively affect these organisms, with implications for leaf litter decomposition and ecosystem functioning in tropical streams.
Microplastics alter the leaf litter breakdown rates and the decomposer community in subtropical lentic microhabitats
AI summary Read the abstract
Researchers exposed leaf litter decomposition systems to microplastics and measured breakdown rates and decomposer community composition, finding that microplastics slowed litter breakdown and shifted the abundance of invertebrate shredders and microbial decomposers. The study suggests microplastics could disrupt nutrient cycling in freshwater ecosystems by impairing a foundational ecological process.
Evidence of micro and macroplastic toxicity along a stream detrital food-chain.
AI summary Read the abstract
Both micro- and macroplastic polyethylene pieces inhibited the decomposition of leaf litter in freshwater streams, with microplastics reducing the feeding activity of stream invertebrates. Since leaf litter decomposition is a critical process that nutrients and energy flow into freshwater food webs, plastic pollution could disrupt these fundamental ecosystem functions.
Microplastics in a tropical lentic environment: dynamics between sediments and the shrimp Macrobrachium amazonicum
AI summary Read the abstract
A year-long study of a tropical Brazilian reservoir found microplastics in 90.9% of shrimp samples, with concentrations higher in gills and sediment than in stomachs, and positive correlations across all compartments indicating active trophic transfer. These results demonstrate that freshwater crustaceans in tropical lentic systems are consistently exposed to microplastics via both filter-feeding and sediment contact, with implications for food safety in regions where such shrimp are consumed.
