The ecological impacts of marine debris: unraveling the demonstrated evidence from what is perceived

This systematic review critically examined the evidence for ecological damage caused by marine debris, including plastic pollution. Researchers found 366 perceived environmental threats from marine debris, and when tested, 83% of those threats were confirmed through scientific studies. This large-scale confirmation of marine debris impacts reinforces concerns about microplastics harming ocean ecosystems that humans depend on for food.

Microplastic contamination in highly consumed wild and cultured Asian seabass from a subtropical coastal region: Exposure and consumer risk assessment

Researchers compared microplastic contamination in wild and farmed Asian seabass from a subtropical coastal region and found plastic particles in the muscle tissue of both groups. Wild fish had slightly higher contamination levels than farmed fish, with polyethylene being the most common plastic type and most particles smaller than half a millimeter. The study includes a consumer risk assessment suggesting that regular consumption of this popular seafood species results in meaningful microplastic exposure for humans.

Microplastics distribution, ecological risk and outflows of rivers in the Bohai Rim region of China - A flux model considering small and medium-sized rivers

Researchers assessed microplastic pollution across rivers flowing into the Bohai Sea in northern China, including smaller waterways that are often overlooked. They found that small and medium-sized rivers contributed nearly half of the total microplastic outflow to the sea, with Shandong province accounting for over 80 percent of the regional total. The study emphasizes that focusing only on major rivers significantly underestimates the true scale of microplastic transport into coastal waters.

Assessment tools for microplastics and natural fibres ingested by fish in an urbanised estuary

Researchers quantified microplastic and natural fiber ingestion in three benthic fish species from Sydney Harbour, Australia, using gut content analysis and spectroscopic identification. They found ingested debris including synthetic and natural fibers as well as synthetic fragments across all species examined. The study demonstrates the value of combining visual analysis with chemical identification techniques like FTIR and Raman spectroscopy to accurately distinguish true microplastics from natural materials in fish gut contents.

Multiple stressors affect function rather than taxonomic structure of freshwater microbial communities

Researchers exposed freshwater pond communities to nutrient pollution and salt stress and found that while the types of bacteria present barely changed, how those communities functioned — specifically how they processed carbon — declined sharply and did not recover. This means standard species surveys may miss serious ecological damage happening at the functional level.

Frontiers in quantifying wildlife behavioural responses to chemical pollution

Researchers investigated how chemical pollution affects wildlife behavior, arguing that conventional study approaches are insufficient and calling for new frontiers in quantifying behavioral responses to contaminants in free-living animal populations.

A global horizon scan of issues impacting marine and coastal biodiversity conservation

Researchers convened a transdisciplinary panel of 30 marine experts to identify 15 emerging issues likely to significantly impact marine and coastal biodiversity over the next decade, including wildfire runoff, novel biodegradable materials, and soft robotics, using a modified Delphi voting process to prioritize from 75 candidate issues.

Blood, lead and spheres: A hindered settling equation for sedimentologists based on metadata analysis

A revised equation for the hindered settling of suspensions of non-cohesive particles was proposed based on metadata analysis of 548 datasets, updating the widely used Richardson-Zaki formulation. The new equation has applications for modeling the settling behavior of microplastic particles in water bodies, improving predictions of plastic deposition and residence times in aquatic systems.

Assessing Organism and Community Responses

This chapter reviews how chemical contamination from both natural and human-altered sources affects aquatic organism health and community structure, including how mining and industrial activities redistribute metals and organic compounds through ecosystems. The authors frame organism and community responses as key indicators of environmental health.

Grand challenges in arachnid genetics and biomaterials

The SORTEE guidelines for data and code quality control in ecology and evolutionary biology

Scientists created new guidelines to help make sure research data and computer code are properly checked before studies get published. Many scientific journals require researchers to share their data, but the quality has been poor and other scientists often can't reproduce the results. These guidelines give editors a clear checklist to verify research quality, which should lead to more trustworthy science that people can rely on for important decisions.

Managing Watersheds for Coral Reefs and Public Health: A Vibrant Oceans Initiative Whitepaper

This whitepaper presents evidence that land-based pollution, including plastics and microplastics from watersheds, is a major driver of coral reef decline, and argues that integrated watershed management linking terrestrial activities to reef health outcomes is essential for reef conservation and coastal public health.

Dual-Compartment Electrocatalytic Oxidation of Polystyrene: Insights into Anode–Cathode Degradation Mechanisms and Differences

Researchers investigated polystyrene microplastic degradation in a dual-compartment electrocatalytic system using peroxymonosulfate catalysis, finding that the cathode achieved a 39.5% weight loss rate compared to lower rates at the anode after 3 hours. The study reveals distinct anode-cathode degradation mechanisms that have been overlooked in single-compartment system studies.

Europium-labelled nanopolystyrene as model nanoplastics for environmental fate investigations: Synthesis and optimisation

Researchers developed a method to track nanoplastics in the environment by embedding the rare-earth element europium into polystyrene nanoparticles, enabling precise detection using single-particle mass spectrometry even at very low concentrations. The europium label stayed locked inside the particles for over a week in both fresh and salt water, making this a reliable tool for studying how nanoplastics move and persist in ecosystems.

A non-lethal SPME-LC/MS method for the analysis of plastic-associated contaminants in coral reef invertebrates

Researchers developed a non-lethal SPME-LC/MS method to detect plastic-associated chemical contaminants in living coral reef invertebrates without harming the animals. This approach enables repeated sampling from the same organisms, allowing scientists to track how chemical exposure from microplastics changes over time.

Pore-size and polymer affect the ability of filters for washing-machines to reduce domestic emissions of fibres to sewage

This study tested whether washing machine filters could meaningfully reduce the emission of synthetic textile fibers into sewage. Results showed filter effectiveness varied significantly by pore size and fiber type, and current consumer filters did not eliminate fiber emissions, suggesting they are insufficient as a standalone solution for microplastic pollution from laundry.
