Microplastics and sea turtle reproduction: A systematic review on nest contamination and developmental risks
AI summary
This research examined the ecotoxicological effects of microplastic exposure on freshwater stingrays, assessing behavioral, physiological, and reproductive impacts in a Neotropical elasmobranch species. The study provides novel data on microplastic effects in cartilaginous fish, expanding ecotoxicological understanding beyond teleost fish models.

Plastic Pollution and Its Ecological Impacts on Sea Turtles: A Comprehensive Review
AI summary Read the abstract
Researchers reviewed the full spectrum of plastic pollution threats to all seven sea turtle species, covering ingestion-driven gastrointestinal obstruction and nutritional dilution, entanglement injuries, and the effects of beach plastic accumulation on nest temperature, hatchling success, and sex ratios.
Microplastics may heat marine turtle nests and produce more females
AI summary Read the abstract
Researchers found that microplastics scattered across sea turtle nesting beaches may raise nest temperatures, potentially skewing hatchling sex ratios toward females — which is already occurring due to climate change. This double pressure from plastic pollution and warming could further threaten already endangered sea turtle populations.
Plastics and Microplastics: Impacts in the Marine Environment
AI summary Read the abstract
Plastics and microplastics have achieved near-universal distribution in marine environments from surface waters to deep-sea sediments, persisting for decades while fragmenting into increasingly smaller and more biologically available particles. The growing concentration of microplastics in oceans represents a long-term threat to marine biodiversity and the food safety of seafood consumed globally.
Ecological and Public Health Effects of Microplastics Pollution
AI summary Read the abstract
Researchers reviewed the ecological and public health consequences of widespread microplastic contamination, emphasizing the particles' ubiquity, persistence, and chemical diversity as compounding risk factors. The review synthesizes evidence on how microplastics harm wildlife and pose potential threats to human health across multiple exposure pathways.
The effects of microplastics on marine ecosystem and future research directions
AI summary Read the abstract
Researchers summarize how microplastics accumulate throughout marine food webs and affect growth, behavior, reproduction, and survival of marine organisms, while calling for standardized testing methods and greater focus on fiber and fragment morphologies to better quantify real-world ecological risks.
