ClearImproving the assessment of ecosystem and wildlife health: microbiome as an early indicator
Researchers reviewed evidence that the microbiome — the community of microorganisms living in environments and within animals — can serve as an early warning system for ecosystem disturbance, rapidly reflecting the impact of human activities before other signs of harm are visible.
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.
Habitat disturbance influences the skin microbiome of a rediscovered neotropical-montane frog
Researchers studied the skin bacteria of a rediscovered montane frog in disturbed versus undisturbed habitats, finding that habitat degradation caused more chaotic and variable microbial communities — a pattern called dysbiosis. On the positive side, frogs in disturbed areas had higher levels of bacteria that may protect against the deadly chytrid fungus Bd, suggesting the frog's microbiome may be adapting to coexist with the pathogen over decades.
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.
Evidence for strong environmental control on bacterial microbiomes of Antarctic springtails
Researchers studied the bacterial communities living inside four species of Antarctic springtails (tiny soil insects) and found that geography — where the springtails lived — was a stronger influence on their gut microbiome than which species they were. This finding helps explain how extreme environments shape the microbial ecosystems inside animals, including those exposed to microplastic contamination.
The effects of food provisioning on the gut microbiota community and antibiotic resistance genes of Yunnan snub-nosed monkey
Researchers compared the gut bacteria and antibiotic resistance genes of Yunnan snub-nosed monkeys that receive supplemental food from a reserve with those of wild-foraging groups. The study found differences in microbial communities between the two groups, suggesting that food provisioning programs, while helpful for population recovery, may alter the gut health of these endangered primates.
Gut microbiota reflect adaptation of cave-dwelling tadpoles to resource scarcity
Researchers studied the gut microbiota of cave-dwelling frog tadpoles that spend three to five years developing underground in resource-scarce conditions. They found that the cave dwellers harbored unique bacterial communities enriched in enzymes for breaking down plant fibers and producing short-chain fatty acids, potentially aiding nutrition under food scarcity. The study suggests that gut microbiota play a key role in helping organisms adapt to extreme, nutrient-limited environments.
The plant microbiota signature of the Anthropocene as a challenge for microbiome research
Researchers argue that human activities during the Anthropocene — the current era of profound human influence on Earth — have fundamentally altered plant-associated microbial communities in ways that threaten ecosystem function and planetary health. Holistic studies are needed to understand and reverse this loss of microbial diversity.
Microplastics and gut microbiomes impact on Yunnan snub-nosed monkeys in the Three Parallel Rivers region in China
Researchers studied microplastic exposure in endangered Yunnan snub-nosed monkeys in China, finding that exposure levels were linked to provisioned food, social dominance hierarchy, and age. Evidence indicates that current microplastic intake levels did not cause significant gut microbiome disruption in these primates, providing a baseline for conservation planning.
Development of Microbial Indicators in Ecological Systems
This review examines the use of microorganisms as bioindicators of ecological health across forest, aquatic, desert, plateau, and artificial ecosystems, highlighting their high environmental sensitivity and underutilized potential compared to animal and plant indicators.
The interplay between host-specificity and habitat-filtering influences sea cucumber microbiota across an environmental gradient of pollution
Researchers studied how pollution levels along a Hong Kong coastline affect the gut and skin microbiomes — communities of bacteria living on and in organisms — of a tropical sea cucumber, finding that the animal maintains its own distinct microbial community even in highly polluted areas. This suggests sea cucumbers have strong internal mechanisms that shape their microbiome independently of the surrounding environment, which may help them survive in contaminated coastal waters.
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.
Exploiting the gut microbiota of aquatic animals as indicators of microplastic pollution using interpretable machine learning models
Researchers analyzed gut microbiota data from 17 aquatic species to determine whether changes in gut bacteria could serve as indicators of microplastic pollution. Using machine learning models, they found that microplastics significantly altered gut bacterial composition in both freshwater and saltwater animals in consistent, detectable patterns. The study suggests that monitoring gut microbiota in aquatic animals could become a practical tool for assessing microplastic contamination in waterways.
Gammaproteobacteria, a core taxon in the guts of soil fauna, are potential responders to environmental concentrations of soil pollutants
Researchers identified a group of gut bacteria called Gammaproteobacteria as a key indicator of soil pollution stress in soil invertebrates, finding these microbes respond sensitively to environmental contaminants and could serve as a biological signal for assessing soil ecosystem health.
Bacterial signatures of anthropogenic pressures in a high-mountain river: a One Health study using full-length 16S profiling
Scientists studied bacteria in a Colombian mountain river and found that human activities like sewage discharge and industrial cooling dramatically changed the types of bacteria living in the water. Areas with more pollution had more harmful bacteria, including some linked to disease and antibiotic resistance. This research helps us understand how pollution affects water quality and could help communities better monitor and protect their water sources from health risks.
Evaluation of the Influence of Habitat Heterogeneity and Human Activities on the Distribution of Microbial Diversity in a High Elevation Drop River
This is a freshwater microbiology study characterizing bacterial diversity in the Huotong River across different land-use zones in China; it is not a microplastics research paper.
The interplay between host-specificity and habitat-filtering influences sea cucumber microbiota across an environmental gradient of pollution
Researchers examined how environmental pollution gradients influence intra-specific variation in microbiota diversity and structure across skin, gut, sediment, and water communities associated with sea cucumbers. They found that both host-specificity and habitat-filtering interact to shape microbial communities along pollution gradients, with animal-associated microbiota showing distinct patterns compared to environmental communities.
Microbiota and Its Importance in Honey Bees
This review examines the role of microbiota in honey bee health, finding that gut microbiome composition is critical for metabolism, immune function, and protection against pathogens, with environmental stressors including pollution threatening bee microbiome stability.
Gut microbiota of aquatic organisms: A key endpoint for ecotoxicological studies
This review examines how environmental contaminants including microplastics, pesticides, heavy metals, and pharmaceuticals affect the gut microbiota of aquatic organisms. Researchers highlight that changes in gut bacterial communities can serve as sensitive indicators of pollution exposure and may have downstream effects on host fitness. The study calls for improved methodologies to better link contaminant-induced shifts in gut microbiota to measurable health outcomes in aquatic species.
The Characteristics of Intestinal Bacterial Community in Three Omnivorous Fishes and Their Interaction with Microbiota from Habitats
This study examined the gut bacterial communities of three omnivorous fish species in artificial fishery habitats, comparing them to bacteria in the surrounding water and sediment. Fish gut microbiomes partially reflected the environmental microbiota, suggesting habitat quality affects fish gut health. This is relevant to microplastics because microplastics alter both aquatic microbial communities and fish gut microbiomes.
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.
