The study highlights an understudied threat to mangrove ecosystems and calls for greater attention to microplastic impacts on these critical coastal habitats.
Mangrove Health: A Review of Functions, Threats, and Challenges Associated with Mangrove Management Practices
This review describes how mangrove forests protect coastlines, store carbon, and support marine life, but are under increasing threat from development, pollution, and climate change. Mangrove loss matters for microplastic pollution because these ecosystems act as natural filters that can trap plastic particles before they spread further into the ocean and food chain.
Comparative metagenomic analysis from Sundarbans ecosystems advances our understanding of microbial communities and their functional roles
Researchers used metagenome analysis — reading all genetic material from environmental samples — to map the microbial communities in the world's largest mangrove forest, the Sundarbans, finding a rich diversity of bacteria including methane-processors, nitrogen-cyclers, and pollution-remediating species absent from nearby non-mangrove soils. The study provides the first comprehensive microbial inventory of this critical ecosystem and highlights its potential for bioremediation of environmental pollutants.
