Food webs depict the tangled web of trophic interactions associated with the functioning of an ecosystem. Understanding the mechanisms providing stability to these food webs is therefore vital for conservation efforts and the management of natural systems. Here, we first characterised a tropical stream meta-food web and five individual food webs using a Bayesian Hierarchical approach unifying three sources of information (gut content analysis, literature compilation and stable isotope data).

Article Synopsis
  • Microplastics are widespread in aquatic ecosystems and can interact with environmental chemicals, potentially enhancing their toxicity to organisms.
  • Researchers evaluated the impact of microplastics by analyzing data from 39 studies, focusing on chemical hydrophobicity and microplastic size.
  • The study found that neither hydrophobicity (log K) nor microplastic size significantly affected the ecotoxicological responses, indicating a need for deeper investigations into the complex interactions between microplastics and chemicals.

Soil runoff and sediment transport are considered as an important vector for particle-bound contaminant transfer from source to receiving waters. Under changing climate conditions and rapid basin development, identification of sediment origins is critical for planning further action to reduce erosion effects, and further pollution to surface waters. The goal of this study was to distinguish sediment sources in a Carpathian basin (Wolnica River, southern Poland) and to perform source-oriented contaminant load estimations.
