ClearMore deterministic assembly constrains the diversity of gut microbiota in freshwater snails
Researchers compared the gut microbiota assembly processes of invasive and native freshwater snails coexisting at multiple sites in southern China. They found that invasive snails exhibited more deterministic gut microbiome assembly with lower microbial diversity, which may contribute to their competitive advantage. The study provides insights into how gut microbial community dynamics may influence the success of invasive species in freshwater ecosystems.
Exploring the Potential of Metatranscriptomics to Describe Microbial Communities and Their Effects in Molluscs
Metatranscriptomics revealed a more complete picture of mussel microbiomes — including bacteria, viruses, fungi, and protozoans — than traditional 16S sequencing alone. The approach also identified host genes whose expression changed with pathogen load, providing new insights into how molluscs respond to microbial infections.
Size-dependent effects of microplastics on intestinal microbiome for Perna viridis
Researchers found that the size of microplastic particles determines how they change the gut bacteria of green mussels, with the smallest particles causing the most disruption to beneficial bacteria and promoting potentially harmful species. Since mussels are widely consumed as seafood, changes to their gut health and the bacteria they carry could affect human food safety.

Shallow-water mussels (Mytilus galloprovincialis) adapt to deep-sea environment through transcriptomic and metagenomic insights
Researchers placed common shallow-water mussels in deep-sea conditions and found that within just 10 days, the mussels' gene activity and gut microbiome shifted to closely resemble those of native deep-sea mussels — revealing a surprisingly rapid adaptive capacity driven by changes in both host biology and microbial communities.

Researchers used a metabolomics approach to investigate the combined effects of microplastics and microcystin-LR on Asian clams, finding that co-exposure caused distinct metabolic responses compared to individual exposures. The study reveals mechanistic interactions between two co-occurring freshwater pollutants at the cellular metabolic level.
The native mussel Mytilus chilensis genome reveals adaptative molecular signatures facing the marine environment
Researchers sequenced and analyzed the genome of the native Chilean blue mussel Mytilus chilensis, identifying adaptive molecular signatures that reflect the species' responses to diverse marine environmental conditions, with implications for understanding resilience in an aquaculture species reliant on wild seed collection.
Biochemical basis of resistance to multiple contaminations in the native and invasive populations of Dreissena polymorpha
This study compared native and invasive populations of the zebra mussel Dreissena polymorpha in their biochemical tolerance to multiple simultaneous stressors including microplastics, examining how antioxidant and detoxification mechanisms differ between populations.
Physiological and transcriptome analysis of Mytilus coruscus in response to Prorocentrum lima and microplastics

The study provides molecular-level evidence of interactive toxicity between two common coastal contaminants.
Microplastic exposure reshapes the virome and virus–bacteria networks with implications for immune regulation in Mytilus coruscus
Researchers exposed mussels to microplastics for seven days and analyzed how the pollution affected viral communities in their tissues. They found that microplastic exposure suppressed DNA virus diversity while activating RNA viral metabolism, and restructured interactions between bacteria-infecting viruses and opportunistic pathogens. The study suggests that microplastics may influence immune function in shellfish by reshaping the viral community and virus-mediated immune interactions.
