Abstract Microbial communities play a crucial role in ocean ecology and global biogeochemical processes. However, understanding the intricate interactions among diversity, taxonomical composition, functional traits, how these factors respond to climate change remains significant challenge. Here, we propose seven distinct ecological statuses by systematically considering structure, potential of microbiome delineate their biogeography. Anthropogenic is expected alter status surface influencing environmental conditions, particularly nutrient oxygen contents. Our predictive model, which utilizes machine learning, indicates that approximately 32.44% may undergo changes from present end this century, assuming no policy interventions. These mainly include poleward shifts main taxa, increases photosynthetic carbon fixation decreases metabolism. proportion can decrease significantly with effective control greenhouse gas emissions. study underscores urgent necessity for implementing policies mitigate change, an perspective.

Abstract Microbial functional ecology is expanding as we can now measure the traits of wild microbes that affect ecosystem functioning. Here, review techniques and advances could be bedrock for a unified framework to study microbial functions. These include our newfound access environmental genomes, collections traits, but also ability microbes’ distribution expression. We then explore technical, ecological, evolutionary processes explain patterns diversity redundancy. Next, suggest reconciling microbiology with biodiversity-ecosystem-functioning studies by experimentally testing significance redundancy efficiency, resistance, resilience processes. Such will aid in identifying state shifts tipping points microbiomes, enhancing understanding how where microbiomes guide Earth's biomes context changing planet.

The shrinkage of glaciers and the vanishing glacier-fed streams (GFSs) are emblematic climate change. However, forecasts how GFS microbiome structure function will change under projected scenarios lacking. Combining 2,333 prokaryotic metagenome-assembled genomes with climatic, glaciological, environmental data collected by Vanishing Glaciers project from 164 GFSs draining Earth's major mountain ranges, we here predict future until end century various scenarios. Our model framework is rooted in a space-for-time substitution design leverages statistical learning approaches. We that declining selection promotes primary production GFSs, stimulating both bacterial biomass biodiversity. Concomitantly, predictions suggest phylogenetic entire clades at risk. Furthermore, genomic projections reveal functions shift, intensified solar energy acquisition pathways, heterotrophy algal-bacterial interactions. Altogether, 'greener' world's accompanied loss have adapted to harshness, consequences for ecosystem functioning.

Abstract Microorganisms dominate marine environments in the polar oceans and are known to harbor greater diversity abundance than was once thought, yet, little is about their biogeographic distribution patterns sediments at a broad spatial scale. In this study, we conducted extensive sampling of along latitudinal transect spanning 2500 km from Bering Sea Arctic Ocean investigate geographical bacteria, archaea, fungi. Our findings revealed that community similarities bacteria fungi decay similar rates with increasing distance (slope: −0.005 −0.002), which much lower rate archaeal communities −0.012). Notably, microbial richness composition showed significant differences region 75−80°N compared other regions 60−75°N. Salinity, temperature, pH, ammonium nitrogen, total organic carbon key factors significantly affect variations. Furthermore, bacterial co‐occurrence networks more complex interactions but modularity fungal counterparts.

ABSTRACT Soil microbiota in intensive agriculture are threatened by pesticides, economic activities, and land‐use changes. However, the interactions among these anthropogenic factors remain underexplored. By analyzing 2356 soil metagenomes from around world, we developed a comprehensive health‐microbial index that integrates microbial diversity, nutrient cycling potential, metabolic primary productivity, health risks to assess how respond factors. Our results indicated was lowest with severe pesticide contamination. Pesticides, combination other climatic factors, exacerbate decline this index. Machine learning predictions suggest approximately 26% of global farmland could between 2015 2040, even under sustainable development scenarios. Even strategies reduce usage, cannot completely halt findings highlight sustaining on scale requires addressing not only management but also broader impacts.
