ClearPopulation differentiation of the endangered salt-marsh snail Ellobium chinense in Japan (Gastropoda: Ellobiidae)
Researchers examined the genetic diversity and population structure of the endangered salt-marsh snail Ellobium chinense across seven Japanese localities using mitochondrial cytochrome c oxidase sequences, finding low genetic diversity and regional population differentiation that has implications for the conservation of this species threatened by coastal land reclamation.
Analysis of Geographical Genetic Differences of Arkshell Populations in Korea
Researchers used genetic analysis to compare two populations of arkshells from different coastal locations in South Korea. The genetic differences found between the two populations have implications for fisheries management and aquaculture stock selection.
Genetic Structure and Historical Dynamics of the Economic Species Phascolosoma esculenta in Southeastern China
Scientists studied the genetics of Phascolosoma esculenta, a type of marine worm that's considered a seafood delicacy in China. They found that these worm populations are becoming inbred and their numbers have been declining for about 300 years, which could hurt the long-term sustainability of this food source. This research helps guide efforts to protect and farm these worms responsibly so they remain available as a healthy seafood option.
Prediction of Oncomelania hupensis distribution in association with climate change using machine learning models
Researchers used machine learning models to predict the current and future geographic range of Oncomelania hupensis — a freshwater snail that carries the parasite causing schistosomiasis in humans — and found climate change is likely to push snail populations northward and westward in China's Yunnan Province. These projections can help public health agencies target snail control efforts in areas that may become newly suitable habitats.
Genomic Prediction of (Mal)Adaptation Across Current and Future Climatic Landscapes
This study developed genomic prediction models to forecast how organisms adapted to current climate conditions might (mal)adapt as climate change shifts selective pressures, offering a tool for conservation planning under future climate scenarios.
DNA Barcoding of Chironomid Larvae (Diptera: Chironomidae) from Large Rivers in South Korea to Facilitate Freshwater Biomonitoring and Public Health Surveillance
Researchers used DNA barcoding to identify 18 chironomid midge larva species from South Korea's four major rivers, including a species recorded for the first time on the Korean Peninsula, and developed a pictorial identification key to support freshwater biomonitoring and drinking water safety programs.
Comparative mitogenome analyses uncover mitogenome features and phylogenetic implications of the subfamily Cobitinae
Researchers conducted the first comparative mitogenomic and phylogenetic analyses within the fish subfamily Cobitinae, uncovering new insights into mitogenome features and evolutionary relationships among loach species.
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.
Using species distribution modelling to identify ‘coldspots’ for conservation of freshwater fishes under a changing climate
Species distribution modeling was used to project future habitat suitability for freshwater fish in southwestern Australia under climate change scenarios, finding that increased temperatures and drought would reduce suitable habitat for several native species. The study evaluates whether existing freshwater reserves will remain effective for conservation as climate conditions shift.
Linking Wetland Ecosystem Services to Fish Genetic Resources with Special Reference to Hilsa Shad (Tenualosa ilisha): A Novel Study from Northeastern Bangladesh
Researchers reviewed the wetland ecosystem services of northeastern Bangladesh in relation to fish genetic resources, with a focus on Hilsa shad (Tenualosa ilisha), documenting the ecological and socioeconomic importance of wetland habitats for this commercially critical species. The study identifies gaps in research on coastal hilsa populations and calls for integrated wetland-fisheries conservation strategies.
A Conservation Assessment of Freshwater Ecosystems in Southwestern Patagonia
This review synthesizes conservation information for freshwater ecosystems in southwestern Patagonia, identifying the region as a globally significant area of relatively intact freshwater biodiversity warranting urgent conservation priority.
Population Genomics of Commercial Fish Sebastes schlegelii of the Bohai and Yellow Seas (China) Using a Large SNP Panel from GBS
This paper is not about microplastics; it is a population genetics study of the black rockfish (Sebastes schlegelii) in Chinese coastal waters, using genomic sequencing to examine genetic diversity and connectivity between fish populations.
Molecular Identification and Phylogenetic Analysis of Hydra vulgaris from Greater Zab River, Iraq
Researchers performed molecular identification of Hydra vulgaris collected from the Greater Zab River in Iraq using the mitochondrial COI gene, generating the first GenBank-registered sequence (OP521891.1) for this species from the country. Phylogenetic analysis revealed minimal genetic divergence from globally reported sequences, confirming species identity and providing baseline genomic data for the region.
Restriction Site-Associated DNA Sequencing Reveals Local Adaptation Despite High Levels of Gene Flow in Sardinella lemuru (Bleeker, 1853) Along the Northern Coast of Mindanao, Philippines
This genetics study assessed population structure and local adaptation in Bali sardinella fish along the northern coast of Mindanao in the Philippines. The findings are relevant to fisheries management and marine biology rather than plastic pollution.
Invertebrate population genetics across Earth's largest habitat: The deep‐sea floor
This review synthesised 77 population genetic studies covering 115 deep-sea invertebrate species, finding genetic diversity comparable to shallow-water taxa and revealing that populations at similar depths are often better connected than those separated by depth gradients.
Small-scale phenotypic differentiation along complex stream gradients in a non-native amphipod
Researchers documented how a non-native freshwater crustacean shows measurable differences in body size and life history traits across short distances within the same stream, suggesting that even recently introduced species can rapidly adapt to local environmental conditions with potential consequences for ecosystem functions like leaf decomposition.
Diet Diversity of the Fluviatile Masu Salmon, Oncorhynchus masou (Brevoort 1856) Revealed via Gastrointestinal Environmental DNA Metabarcoding and Morphological Identification of Contents
Researchers investigated the dietary diversity of fluviatile Masu salmon (Oncorhynchus masou) using gastrointestinal content analysis, seeking to expand knowledge of the trophic ecology of this nationally protected species endemic to the North Pacific. The study documents the range of prey items consumed by Masu salmon in riverine habitats and provides baseline ecological data for conservation and fisheries management.
Diversity and Habitat Adaptation of Endemic Fish in Tropical River Ecosystems
Researchers assessed the diversity and habitat adaptation of endemic fish across nine survey sites in Lake Tondano, the Tondano River, and urban rivers in Manado, North Sulawesi using the Shannon-Wiener diversity index and multivariate methods. The upstream Tondano River segment showed the highest diversity (H' = 2.71), while urban rivers exhibited low diversity associated with habitat degradation.
Habitat changes of a small endemic euryhaline fish species in the northern margin of the South China Sea under the background of global warming

Anthropogenic land uses shape denitrification-related microbial communities in freshwater river ecosystems
Researchers investigated how anthropogenic land uses (agricultural and urbanized) versus natural land uses shape denitrification-related microbial communities in the Weihe and Hanjiang Rivers in China's Qinling Mountains using deep 16S rRNA gene sequencing of water and sediment samples. Results revealed that land-use type significantly alters the composition and function of nitrogen-cycling microbial communities in freshwater river ecosystems.
