Research Progress on the Comprehensive Response Mechanisms of Marine Organisms to Multiple Environmental Stressors
AI summary Read the abstract
Researchers reviewed how combinations of ocean warming, acidification, hypoxia, and microplastic pollution interact to produce biological responses in marine organisms that deviate substantially from single-stressor predictions, highlighting strong species-specific differences and calling for multi-stressor models to better predict ecosystem-level consequences.
The ocean constitutes a vital component of the Earth's ecosystem, serving as the breeding and habitat ground for marine organisms. Currently, the global marine ecosystem is confronting combined threats from multiple environmental stressors, such as seawater warming, acidification, hypoxia, and microplastic pollution. Research focusing solely on individual stressors can hardly reveal the authentic response patterns of marine organisms accurately. This paper presents a comprehensive review. It systematically integrates cutting-edge research findings from recent years. The review centers on two core themes. These themes are the interactive effects of multiple environmental stressors and the response mechanisms of marine organisms. Studies indicate significant species-specific differences in organism responses to combined stress. These differences exist across various organism groups. Additionally, the interactive effects of multiple environmental stressors often induce biological responses. These responses deviate from the predictions derived from single-factor studies. The research results presented herein can provide crucial theoretical support for the conservation of marine biological resources, the restoration of biodiversity, and the protection of the marine ecological environment. Meanwhile, they lay a foundation for the establishment of predictable marine stress-response relationship models.

Interactive Threats: Multi-stress Systems in Aquatic Environments
AI summary Read the abstract
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.
Oysters under anthropogenic pressure: A cellular perspective on the interactive effects of microplastic pollution and climate change
AI summary Read the abstract
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.
Leveraging Multi-target Strategies to Address Plastic Pollution in the Context of an Already Stressed Ocean
AI summary Read the abstract
This review examines how plastic pollution interacts with other stressors affecting ocean health, using the Ocean Health Index as a framework. Researchers argue that addressing plastic pollution requires multi-target strategies that account for the already degraded state of marine ecosystems. The study highlights how plastics compound existing environmental pressures on the ocean, from habitat destruction to biodiversity loss.
Application of marine organisms at multi-trophic level to study the integrated biological responses induced by microplastics through food-chain
AI summary Read the abstract
Researchers used marine organisms across multiple trophic levels to study how microplastics move and accumulate through the food chain, finding that toxicological effects intensify at higher trophic levels due to bioaccumulation of plastic particles and associated chemical pollutants.
