The Effect of Rumen Microbiota in The Susceptibility of Subacute Ruminal Acidosis in Dairy Cows
Researchers studied how differences in rumen bacteria and fungi affect whether dairy cows develop a metabolic disease caused by high-grain diets. This gut microbiome research is not directly related to microplastics but is relevant to understanding how gut microbial communities influence susceptibility to environmental exposures.
Comparative Analysis of Nasal Microbial Community between Tibetan Sheep with different Ages
Researchers compared nasal microbial communities in adult and young Tibetan sheep using amplicon sequencing, finding that young sheep had greater bacterial diversity at the genus level with 185 genera significantly more abundant, though overall alpha diversity indices were similar between age groups.
Influence of different irrigation methods on the alfalfa rhizosphere soil fungal communities in an arid region

Developmental Dynamics of the Gut Virome in Tibetan Pigs at High Altitude: A Metagenomic Perspective across Age Groups
Researchers profiled the gut virome of Tibetan pigs at high altitude using metagenomic sequencing, tracking viral community dynamics across different developmental stages. 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.
Application of Organic Fertilizer Changes the Rhizosphere Microbial Communities of a Gramineous Grass on Qinghai–Tibet Plateau
Researchers examined how organic fertilizer application altered rhizosphere microbial communities in a gramineous grass, finding significant shifts in bacterial diversity and composition that may influence nutrient cycling and soil health in grassland ecosystems.
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.
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.
Identification and prevalence of fluke infection in yak and Tibetan sheep around Qinghai Lake, China
This Chinese study identified and assessed the prevalence of liver and rumen flukes in yak and sheep grazing around Qinghai Lake. While focused on veterinary parasitology rather than microplastics, the study contributes to understanding the health of livestock in a remote region where plastic contamination of grazing land is an emerging concern.
Effect of Growth Media on the Diversity of Neocallimastigomycetes from Non-Rumen Habitats
Researchers investigated how different growth media affect the diversity of anaerobic fungi from non-rumen habitats, finding that medium composition strongly influences which species are detected. Many novel species from diverse habitats went undetected on standard media. Broader culture approaches are needed to capture the full diversity of these ecologically important fungi.
Divergent gut microbial metabolism supports niche partitioning in giant and red pandas
Researchers found that giant pandas and red pandas have evolved distinct gut microbial metabolic pathways that support niche partitioning, with differences in energy acquisition modes and dietary strategies reflected in their microbiome composition. These divergent metabolic strategies represent a highly coordinated adaptive system linked to ecological differentiation between the two species.
Association of Fungi in the Intestine of Black Carp and Grass Carp Compared with their Cultured Water
Researchers characterized and compared the intestinal fungal communities of grass carp and black carp and their cultured water using high-throughput sequencing, finding species-specific differences in gut fungal composition that correlated partially with surrounding water microbiota.
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.
Diet shapes cold‐water corals bacterial communities
Researchers found that diet significantly shapes the bacterial communities living in cold-water corals, with carnivorous and herbivorous diets producing distinct microbiomes. The study sheds light on the ecological factors driving microbial diversity in deep-sea coral ecosystems.
Fungal Diversity in Two Wastewater Treatment Plants in North Italy
Researchers characterized fungal diversity in two wastewater treatment plants in northern Italy, finding diverse communities including molds and yeasts whose composition varied with treatment stage and influent quality, suggesting fungi may play underappreciated roles in contaminant removal including potential interactions with microplastics.
Variation in the gut microbiota of wild Eurasian otter (Lutra lutra) likely reflects diet shifts between snow-free and snow seasons
Researchers studied the gut bacteria of wild Eurasian otters across two seasons, finding that their microbiome shifts significantly depending on what they eat — fish in summer versus high-fat prey in winter. The study notes that future comparisons with urban otters could reveal whether microplastic contamination in waterways disrupts their gut health.
Short‐term effects of mineral and combined mineral‐organic fertilization in soil microbial communities
A one-year fertilization trial in a Qinghai-Tibet Plateau greenhouse found that both mineral and combined mineral-organic fertilization increased bacterial richness and decreased fungal diversity compared to unfertilized soil, with available phosphorus as the primary driver of microbial community structure changes.
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.
