Soil microorganisms are crucial for nutrient cycling, with abundant and rare taxa playing distinct roles. However, the mechanisms by which soil microbes influence cycling under different crop types remain unclear.

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.

Microbes of low abundance (i.e., rare biosphere) are involved in the ability coral as holobiont, to respond and acclimatize local global environmental disturbances. However, no complete characterization these important microbial assemblages has been conducted. Outlining would greatly benefit our understanding their ecological role coral-microbial association. Here, we assessed bacterial biosphere hermatypic corals Pocillopora cf. damicornis P. verrucosa, well surrounding seawater sediment, at six sites northeastern Tropical Eastern Pacific, using MiSeq Illumina sequencing 16S rRNA gene region V4. The presented spatial differences among with different anthropogenic stress levels. four biotopes a similar microbiota. high stress, Vibrionaceae family was recorded, while locations moderate showed several sequences related Flavobacteriaceae Bacillaceae families. This study represents first approach knowledge verrucosa northeast Pacific its possible use bioindicator response magnitude stress.

Abstract Evidence is mounting that plant diversity loss erodes ecosystem function by altering biochemical processes regulated diverse organisms both above‐ground and below‐ground. However, we know little about how of influences soil biodiversity, especially whether ecologically rare and/or functionally distinctive plants leads to reduction in microbes associated with multifunctionality. In species‐rich alpine meadow communities on the Tibetan Plateau, conducted a 12‐year species removal experiment reveal effects biodiversity losing many forbs versus few dominant sedges several common species. We found forbs, rather than plants, significantly decreased richness bacteria fungi decreasing microbial taxa later years. This decline was attributable not only but also increased abundance fungivorous omnivorous nematodes. Synthesis . The study revealed induces through amplified below‐ground multitrophic interactions. Loss triggers larger shifts community alter food web structure functioning.
