ClearInteractive effects of microplastic pollution and heat stress on reef-building corals
This study tested the combined effects of microplastic exposure and heat stress on reef-building corals, finding that the combination caused more damage than either stressor alone. As climate change raises ocean temperatures, the simultaneous pressure from plastic pollution may accelerate coral reef decline.
Integrated toxicokinetic/toxicodynamic assessment modeling reveals at-risk scleractinian corals under extensive microplastics impacts
An integrated toxicokinetic/toxicodynamic modeling approach was applied to quantify microplastic-coral interaction dynamics across multiple scleractinian coral species, identifying species-specific vulnerability thresholds and predicting which coral species are most at risk under current microplastic pollution levels.
Microplastic exposure under future oceanic conditions further threatens an endangered coral, Acropora cervicornis
Researchers exposed the threatened Caribbean coral Acropora cervicornis to microplastics under predicted future ocean conditions (acidification and warming) and found that combined stressors were more damaging than individual stressors. Growth rates declined and photosynthetic efficiency dropped most under the combined microplastic plus ocean warming and acidification treatment.
A coupled model for the linked dynamics of marine pollution by microplastics and plastic-related organic pollutants
This study developed a mathematical model linking the spread of microplastics in the ocean with the organic pollutants they carry, simulating how microplastics act as transport vehicles for harmful chemicals. The model helps assess the combined ecological risk of plastic pollution and the contaminants it concentrates.
Research progress in ecotoxicology of climate change coupled with marine pollutions
This review examined how rising ocean temperatures and acidification from climate change interact with marine pollutants including microplastics, finding that combined stressors often produce worse effects than either alone. The research underscores that plastic pollution cannot be addressed in isolation from the broader context of global climate change.
Oxidative stress and histological alterations in coral Briareum violacea co-exposed to ocean acidification and microplastic stressors
Researchers exposed the coral Briareum violacea to combined ocean acidification and polyethylene microplastics for 21 days. The study found that the combination of lower pH and microplastic exposure caused greater oxidative stress and tissue damage than either stressor alone, suggesting that these two major environmental threats may have compounding effects on coral health.
Micro- and nanoplastics effects in a multiple stressed marine environment
Researchers examined how micro- and nanoplastics interact with other environmental stressors in marine settings, finding that realistic multi-stressor scenarios can amplify or modify plastic toxicity in ways single-exposure studies miss.
Interactive Threats: Multi-stress Systems in Aquatic Environments
Researchers examined how aquatic organisms face multiple simultaneous stressors — including plastic pollution, climate change, altered pH, and habitat loss — finding that the combined interactive effects of these threats are poorly understood yet critical to developing effective conservation and management strategies.
Environmental behavior and toxic effects of micro(nano)plastics and engineered nanoparticles on marine organisms under ocean acidification: A review.
This review examined how ocean acidification interacts with the toxicity of micro- and nano-plastics and engineered nanoparticles in marine ecosystems, finding that lower pH can alter particle surface chemistry and enhance toxic effects in some organisms. The combined stressor perspective is important because climate change and plastic pollution are co-occurring in the same marine environments.
The Distribution and Impact of Microplastics on Coral Reefs: an Ecosystem Approach
This study examines the distribution and ecological impact of microplastics on coral reef ecosystems, providing a Ph.D.-level ecosystem approach to understanding how microplastic pollution affects reef health and biodiversity.
Interactive effects of microplastic pollution and heat stress on reef-building corals
Researchers tested the combined effects of microplastic pollution and heat stress on five reef-building coral species in controlled laboratory experiments. They found that while heat stress caused significant bleaching, tissue death, and reduced photosynthetic efficiency, microplastics alone had only minor effects at ambient temperatures, suggesting that climate change remains a far greater threat to coral reefs than microplastic pollution.
Exposure to global change and microplastics elicits an immune response in an endangered coral
Researchers exposed an endangered coral species to combined stressors of elevated seawater temperature, reduced pH, and microplastics, finding that these global change factors together with local microplastic pollution elicit measurable immune responses, suggesting additive or synergistic stress effects on reef-building corals.
Unraveling individual and combined toxicity of microplastics and tetracycline at environment-related concentrations to coral holobionts
Researchers tested how microplastics alone and combined with the antibiotic tetracycline affect coral organisms at levels actually found in the ocean. The combination was more toxic than either pollutant alone, disrupting the coral's symbiotic algae, microbiome, and immune responses. Since coral reefs support fisheries and coastal communities worldwide, this damage from microplastic pollution could have cascading effects on both marine ecosystems and the people who depend on them.
Modeling the Impact of Microplastics on Metabolic Rates andMortality of Zooplankton
Researchers developed a mathematical model to predict how microplastic exposure affects the metabolism and survival rates of zooplankton, the tiny animals that form the base of aquatic food chains. Understanding these effects is important because changes to zooplankton populations ripple upward through ecosystems to fish and the species that eat them.
Climate Change and Microplastics: Their Impacts and Interactions with Corals and Coral Reefs
This PhD thesis examines the combined impacts of climate change and microplastic pollution on corals and coral reef ecosystems, investigating how these two stressors interact and compound each other. The dissertation, completed at the University of Washington in 2024, contributes to understanding the dual threats facing reef systems globally.
Exploring the Evolution of the Food Chain under Environmental Pollution with Mathematical Modeling and Numerical Simulation
This paper is not directly about microplastics; it presents a mathematical model of food chain dynamics under generalized environmental pollution, exploring how contaminants destabilize predator-prey relationships but does not focus specifically on microplastics.
Modelling to inform the conservation and management of aquatic ecosystems: A synthesis of five case studies
Not relevant to microplastics — this paper presents five modeling case studies for managing aquatic ecosystems under threats including invasive species, over-exploitation, and climate change; microplastics are briefly mentioned as one of many stressors but are not the paper's focus.
Impacts of microplastics on reef-building corals: Disentangling the contribution of the chain scission products released by weathering
Researchers investigated how microplastics harm reef-building corals by separating the effects of physical contact from the chemical leachates released as plastics degrade. They found that while physical interaction with the particles caused immediate tissue damage, the chemical breakdown products from aged plastics created additional toxic effects. The study highlights that weathered microplastics pose a compound threat to coral health through both mechanical abrasion and chemical contamination.
Predicting microplastic dynamics in coral reefs: presence, distribution, and bioavailability through field data and numerical simulation analysis
Researchers combined field sampling at Australia's Lizard Island with numerical hydrodynamic modeling to map microplastic distribution across reef habitats and assess bioavailability to corals, fish, sponges, and other species. Sediment was the dominant accumulation zone, biota contained microplastics at concentrations reflecting feeding strategies, and model simulations predicted particle trajectories within the reef system.
Microplastics: impacts on corals and other reef organisms
This study reviewed the growing body of evidence on how microplastics and nanoplastics affect corals and other reef organisms. Researchers found that these plastic particles can impair coral feeding, growth, and reproduction, and may worsen the effects of other stressors like ocean warming. The review highlights that plastic pollution represents an additional serious threat to already vulnerable reef ecosystems worldwide.
Impact of micro-and nanoplastic contamination on reef-building corals
Researchers exposed two tropical coral species to micro- and nanoplastics of varying polymer types and assessed bleaching, symbiont loss, and tissue damage. Both species showed stress responses including reduced photosynthetic efficiency and partial bleaching, with effects varying by plastic type and size, suggesting reef-building corals are vulnerable to plastic pollution.
Increasing microplastic concentrations have nonlinear impacts on the physiology of reef-building corals
Researchers exposed reef-building corals to increasing microplastic concentrations and found nonlinear effects on coral physiology, suggesting that low and high MP levels may have qualitatively different biological impacts. The findings complicate predictions of how coral reefs will respond as ocean MP pollution increases.
Toxicity of microplastics and nano-plastics to coral-symbiotic alga (Dinophyceae Symbiodinium): Evidence from alga physiology, ultrastructure, OJIP kinetics and multi-omics
Researchers studied how microplastics and nanoplastics damage Symbiodinium, the algae that live inside coral and keep reefs alive. Even at concentrations found in the real environment, the plastic particles disrupted photosynthesis, caused oxidative stress, and triggered metabolic problems in the algae. Since the breakdown of this coral-algae partnership leads to coral bleaching, microplastic pollution could threaten the reef ecosystems that support fisheries and coastal communities worldwide.
Microplastics in Natural and Artificial Reefs
This review examines microplastic pollution in both natural and artificial reef ecosystems, summarizing how plastic particles accumulate in reef structures, affect coral and associated organisms, and interact with other stressors threatening reef health worldwide.
