ClearThe effect of climate change and microplastics on the physiology of marine invertebrates of economic interest
This thesis examines how climate change and microplastic pollution interact to affect the physiology of marine invertebrates important for aquaculture. Combined stressors were found to have compounding effects on organisms like mussels and oysters, threatening both ecosystems and food security.
Unraveling the interplay between environmental microplastics and salinity stress on Mytilus galloprovincialis larval development: A holistic exploration
Researchers studied how environmental microplastics and increased salinity together affect the early development of Mediterranean mussel larvae. The combination caused larval deformities, developmental problems, and changes in gene activity related to shell formation, stress response, and cell damage. These findings are concerning because climate change is altering ocean salinity in coastal areas where microplastic pollution is also heavy, and mussels are a food source that could pass accumulated microplastics to humans.
Differential responses of selectively bred mussels (Perna canaliculus) to heat stress—survival, immunology, gene expression and microbiome diversity
This study examined how selectively bred green-lipped mussels respond to heat stress, finding that genetic background significantly influenced survival rates, immune responses, and gene expression during heat challenges. While not directly about microplastics, the research is relevant because environmental stressors like microplastic pollution can compound heat stress effects on shellfish. Understanding how marine organisms cope with stress helps predict how additional pressures from plastic pollution might affect seafood species.
Using Biometrics, Behavioral Observations, and Multiple Molecular Techniques to Assess the Impacts of Changes in Temperature and Salinity on the Common Bay Mussel (Mytilus trossulus)
This study used multiple molecular and physiological techniques to assess how the common bay mussel responds to changes in temperature and salinity, providing baseline data for understanding climate change impacts. Mussels are also used as sentinel organisms for monitoring microplastic contamination in coastal waters.
The multiple responses of Mytilus galloprovincialis in the multi-stressor scenario: Impacts of low pH, low dissolved oxygen, and microplastics
Researchers exposed Mediterranean mussels to the combined stressors of low pH, low dissolved oxygen, and microplastics for 15 days. While whole-organism functions like respiration were unaffected, the study found significant cellular-level impacts, suggesting that microplastics interact with ocean acidification and deoxygenation to cause subtle but measurable stress in marine invertebrates.
Oysters under anthropogenic pressure: A cellular perspective on the interactive effects of microplastic pollution and climate change
Researchers exposed oysters to microplastics under combined conditions of elevated temperature and ocean acidification, finding that climate change stressors significantly altered the cellular response to MP pollution. Temperature had a stronger effect than acidification, and combined stressors produced non-additive interactions in immune and oxidative stress markers.
Effect of hypoxia and reoxygenation on the nervous system of the Mediterranean mussel Mytilus galloprovincialis
Despite its title referencing neuroplasticity in marine mussels, this paper studies how the Mediterranean mussel's nervous system adapts to cycles of low oxygen and re-oxygenation — not microplastic pollution. It examines molecular and cellular mechanisms of hypoxia tolerance in marine bivalves and is not relevant to microplastics or human health.
Indication of the impact of environmental stress on the responses of the bivalve mollusk Unio tumidus to ibuprofen and microplastics based on biomarkers of reductive stress and apoptosis
Researchers compared freshwater mussels from clean and contaminated sites exposed to microplastics and ibuprofen, finding that chronically stressed populations showed altered biomarker responses for reductive stress and apoptosis, highlighting how environmental history modulates pollutant sensitivity.
The Eco-Immunological Relevance of the Anti-Oxidant Response in Invasive Molluscs
Not relevant to microplastics — this review examines how antioxidant defence mechanisms in invasive mollusc species help them survive environmental stress and support immune function, with no focus on microplastic exposure.
Physiological and transcriptome analysis of Mytilus coruscus in response to Prorocentrum lima and microplastics
The combined effects of diarrhetic shellfish toxin and microplastics on the mussel Mytilus coruscus were assessed at physiological and transcriptomic levels, revealing synergistic disruption of immune function, antioxidant responses, and metabolic pathways. The study provides molecular-level evidence of interactive toxicity between two common coastal contaminants.
Microplastics can aggravate the impact of ocean acidification on the health of mussels: Insights from physiological performance, immunity and byssus properties
Researchers found that the combination of ocean acidification and microplastic exposure weakened mussel immune systems, reduced feeding performance, and degraded the quality of byssus threads used for attachment. The study suggests that co-occurring ocean acidification and microplastic pollution could increase the vulnerability of bivalves to disease and dislodgement, threatening their survival in future marine environments.
The combined effects of polystyrene microplastics and temperature stress on Mytilus galloprovincialis, Lamarck, 1819
Researchers investigated the combined effects of polystyrene microplastics and rising water temperatures on Mediterranean mussels. The study found that microplastic exposure amplified temperature-related stress, leading to increased mortality, greater oxidative damage, and more severe tissue changes, suggesting that these two environmental stressors interact to worsen harm to marine organisms.
Gene Expression Analysis in Freshwater Mussels (Unio stevenianus) Collected from Pollutant-Associated Environment
Not relevant to microplastics — this study uses freshwater mussels in a Turkish river as biological sentinels of general water pollution by measuring stress-related gene expression levels, without a focus on microplastic contamination.
Different recovery patterns of the surviving bivalve Mytilus galloprovincialis based on transcriptome profiling exposed to spherical or fibrous polyethylene microplastics
Researchers used gene expression analysis to study how Mediterranean mussels respond to and recover from exposure to different shapes of polyethylene microplastics. They found that spherical and fibrous particles triggered distinct stress responses and different recovery patterns over a 14-day period. The study suggests that the shape of microplastics matters significantly in determining their biological impact on marine organisms.
Impact of environmental microplastics alone and mixed with benzo[a]pyrene on cellular and molecular responses of Mytilus galloprovincialis
Researchers exposed Mediterranean mussels to environmentally collected microplastics from a beach, both alone and combined with the pollutant benzo[a]pyrene, at ecologically relevant concentrations. The study found that even short-term exposure caused cellular and molecular responses in the mussels, and the combination of microplastics with chemical pollutants produced different effects than either contaminant alone.
Effects of microplastics contamination on marine biota
Researchers exposed mussels to PVC microplastics under different conditions, finding that short-term exposure caused physiological stress influenced by plastic additives and concentration, while long-term exposure allowed some adaptation. Microplastics were transferred along the food chain to predators but were not absorbed into tissues, suggesting physical passage rather than bioaccumulation.
Microplastics in the deep: Suspended particles affect the model species Mytilus galloprovincialis under hyperbaric conditions
Researchers exposed juvenile Mediterranean mussels to polyethylene microplastics at three concentrations and three pressure levels (1, 4, and 50 Bar) for 96 hours to simulate deep-sea conditions. Microplastics significantly reduced filtration rates and triggered oxidative stress, with transcriptomic analysis revealing pressure-dependent differences in how mussels respond to plastic exposure.
Investigating the combined effects of microplastics and suspended sediment on mussels in controlled experimental conditions.
Researchers investigated the combined effects of microplastics and suspended sediment on mussels under controlled experimental conditions, examining how simultaneous exposure to both stressors affects physiological responses compared to exposure to either stressor alone.
Anthropogenic modifications and their impacts on shellfish physiology
This thesis reviews how human activities — including aquaculture, coastal development, and pollution — have altered marine habitats over centuries, with consequences for shellfish physiology and ecosystem function. Shellfish are important sentinels for monitoring microplastic exposure and accumulation in coastal ecosystems.
The stress-immunity axis in shellfish.
This review examines the stress-immunity relationship in shellfish, covering how environmental stressors — including chemical contaminants like microplastics — activate immune responses and affect shellfish health. Since shellfish are consumed by humans and accumulate microplastics from the water they filter, understanding how plastic pollution stresses these animals is important for seafood safety.
Exposure of Mytilus galloprovincialis to Microplastics: Accumulation, Depuration and Evaluation of the Expression Levels of a Selection of Molecular Biomarkers
Researchers exposed Mediterranean mussels to a realistic mixture of microplastic types and then tested whether a standard purification process could remove them. They found that purification significantly reduced microplastic contamination in the mussels and that molecular biomarkers in the gills could detect the biological effects of exposure. The study suggests that both purification protocols and molecular monitoring tools could help address microplastic risks in farmed shellfish.
Responses of Mytilus galloprovincialis in a Multi-Stressor Scenario: Effects of an Invasive Seaweed Exudate and Microplastic Pollution under Ocean Warming
Researchers exposed mussels to a combination of invasive seaweed exudate, polyethylene microplastics, and elevated temperatures to study their combined effects. The study found that simultaneous exposure to all three stressors greatly reduced byssal thread production and depleted antioxidant defenses in gill tissue, suggesting that multiple environmental stressors can amplify harmful effects on marine organisms.
Toxicological Impacts of Microplastics: Effects on Levels of Cellular Thiols in Mytilus galloprovincialis
Researchers investigated how microplastic exposure affects cellular thiol antioxidants in Mediterranean mussels, finding that short-term exposure altered glutathione and ovothiol levels, indicating oxidative stress as a key mechanism of microplastic toxicity in benthic species.
