The study identified novel bacteriophages and found that gut viral diversity changed substantially with age, providing baseline data on virome development in this understudied livestock population.
Different living environments drive deterministic microbial community assemblages in the gut of Alpine musk deer (Moschus chrysogaster)
Researchers found that captive and wild Alpine musk deer harbor significantly different gut microbial communities, with living environment being a deterministic factor in shaping microbial assembly and diversity in this endangered ruminant.
Comparative analysis of gut fungal composition and structure of the yaks under different feeding models
Researchers compared the gut fungal communities of wild yaks, house-fed domestic yaks, and grazing domestic yaks on the Tibetan plateau. They found that wild and grazing yaks had significantly more diverse gut fungal communities than house-fed yaks, with the feeding model strongly influencing which fungal species thrived. The study suggests that natural grazing supports a richer gut microbiome in yaks compared to indoor feeding, with potential implications for animal health and digestion.
Comparative Analysis of the Gut Microbiota between Two Horse Species
Researchers compared the gut microbiota of native Mongolian horses and imported Dutch Warmblood horses using genetic sequencing. They found notable differences in bacterial community composition between the two breeds, suggesting that host genetics plays a role in shaping gut microbial populations. The study adds to the growing understanding of how the gut microbiome varies across closely related animal species.
Exploring the Microdiversity Within Marine Bacterial Taxa: Toward an Integrated Biogeography in the Southern Ocean
Researchers used advanced sequencing techniques to study the fine-scale diversity and geographic distribution of bacteria in the Southern Ocean. Understanding ocean microbial communities is relevant to microplastic research because plastics in the ocean host distinct microbial communities that can alter local ecology.
Bacterial Community Structure and Its Influencing Factors in Surface Sediments of the Nyang River in the Dry Season, China
Researchers analyzed bacterial community diversity in surface sediments of the Nyang River in Tibet using high-throughput sequencing, finding that climate warming and human activities along this plateau river have measurably shaped microbial composition and structure.
Rare Bacteria Can Be Used as Ecological Indicators of Grassland Degradation
Researchers used full-length 16S rRNA sequencing to study bacterial communities across degraded grasslands on the Qinghai-Tibet Plateau, finding that rare bacterial taxa were more sensitive to grassland degradation and soil nutrient changes than abundant taxa, and that rare bacteria may serve as reliable ecological indicators of grassland health.
Metagenomic insights into isolable bacterial communities and antimicrobial resistance in airborne dust from pig farms
Researchers studied bacterial communities and antimicrobial resistance in airborne dust from pig farms in Thailand using metagenomic sequencing. The study found the highest bacterial concentrations inside pig houses, with Staphylococcus and Enterococcus being the most frequently isolated species, and identified that the same resistant bacteria appeared across dust, feed, and fecal samples on individual farms.
Transcriptome Profiling of Developing Testes and Spermatogenesis in the Qianbei Ma Goat
This paper is not relevant to microplastics research — it uses RNA sequencing to profile gene expression changes during testis development and spermatogenesis in Qianbei Ma goats at different stages of maturity.
Influence of Age of Infection on the Gut Microbiota in Worker Honey Bees (Apis mellifera iberiensis) Experimentally Infected with Nosema ceranae
Researchers studied how infection with the gut parasite Nosema ceranae affects the microbiome of honey bees at different ages. The study found that infected bees, especially those infected shortly after emerging, showed significant shifts in their gut bacteria populations, suggesting that both age and infection timing play important roles in how bee gut health is disrupted.
Different Distribution of Core Microbiota in Upper Soil Layer in Two Places of North China Plain
Researchers compared the composition and distribution of core soil microbiota in upper soil layers at two locations on the North China Plain, examining how habitat and dominant plant species shape bacterial community structure relevant to nutrient cycling and carbon storage. The study found meaningful differences in microbial community composition between the two sites, reflecting local environmental influences.
Comparative Analysis of Gut Microbiota Provides Insights into High-altitude Adaptation in Rana kukunoris on the Qinghai-Xizang Plateau
Researchers used 16S rRNA gene sequencing to characterize and compare the gut microbiota of the high-altitude frog Rana kukunoris on the Qinghai-Xizang Plateau with two low-altitude frog species, Rana amurensis and Rana dybowskii. The comparative analysis aimed to identify microbial community differences that may reflect adaptive strategies to extreme high-altitude conditions including low oxygen and harsh temperatures.
Investigation of Soil-Dwelling Bacterial Community Changes Induced by Microplastic Ex posure Using Amplicon Sequencing
Researchers analyzed soil bacterial community composition after microplastic contamination, finding that different polymer types caused distinct shifts in microbial diversity and functional groups, with implications for soil nutrient cycling and agricultural productivity.
Large-Scale Integration of Amplicon Data Reveals Massive Diversity within Saprospirales, Mostly Originating from Saline Environments
This paper is not about microplastics — it analyzes global bacterial diversity within the order Saprospirales using environmental DNA databases.
Differences in Root Endophytic Bacterial Communities of Chinese Cork Oak (Quercus variabilis) Seedlings in Different Growth Years
Researchers used high-throughput sequencing to compare root endophytic bacterial communities in Chinese cork oak seedlings of different ages, finding that seedling age influences the composition and functional potential of root microbiomes in forest regeneration contexts.

Researchers collected floating microplastics from a bay in the Mediterranean and analyzed their bacterial biofilm communities using 16S rRNA sequencing, finding that microbial communities on plastics were distinct from surrounding seawater and differed between polymer types.
Virome of high-altitude canine digestive tract and genetic characterization of novel viruses potentially threatening human health
Researchers conducted a metagenomics analysis of the viral community in the digestive tracts of nearly 2,000 dogs from high-altitude regions in China. The study identified 203 novel viruses across 11 known families, including the first detection of hepatitis E virus in dogs, highlighting potential zoonotic risks that warrant further surveillance.
Linear responses of soil microbiomes, metagenomic and metabolomic functioning across ecosystems along water gradients in the Altai region, northwestern China
Researchers analyzed soil microbial communities, their genetic functions, and metabolic profiles across four ecosystems along a water gradient in the Altai region of China. Microbial diversity and carbon and nitrogen cycling functions increased linearly with soil moisture, demonstrating how hydrology shapes ecosystem-level microbial processes.
Effects of residual mulching films with different mulching years on the diversity of soil microbial communities in typical regions
Researchers examined four cotton fields in Xinjiang, China with varying polyethylene mulch film histories (0-25 years) using high-throughput sequencing to assess how residual film and microplastics affect soil microbial communities. They found that short-term mulching (0-10 years) increased microbial diversity while continuous 25-year mulching significantly decreased bacterial diversity, with Proteobacteria and Ascomycetes dominating, and residual film accumulation reducing bacterial community diversity without significantly impacting fungal diversity.
