Metabolic rules of microbial community assembly [PDF]

, 2020
AbstractTo develop a quantitative theory that can predict how microbiomes assemble, and how they respond to perturbations, we must identify which descriptive features of microbial communities are reproducible and predictable, which are unpredictable, and why.

Salinity Is a Key Determinant for Soil Microbial Communities in a Desert Ecosystem

mSystems, 2019
Soil salinization is a growing environmental problem caused by both natural and human activities. Excessive salinity in soil suppresses growth, decreases species diversity, and alters the community composition of plants; however, the effect of salinity ...

Microbial community composition, and not pH, influences lake sediment function

Ecosphere, 2022
Lake sediment microbial communities vary across ecosystems and are often differentiated across pH. Additionally, these pH‐mediated differences in community composition are often correlated with changes in sediment functioning, such as methane and carbon ...

Contrasting Community Assembly Forces Drive Microbial Structural and Potential Functional Responses to Precipitation in an Incipient Soil System

Frontiers in Microbiology, 2021
Microbial communities in incipient soil systems serve as the only biotic force shaping landscape evolution. However, the underlying ecological forces shaping microbial community structure and function are inadequately understood.

Stochastic microbial community assembly decreases biogeochemical function [PDF]

Processes, 2017
AbstractEcological mechanisms influence relationships among microbial communities, which in turn impact biogeochemistry. In particular, microbial communities are assembled by deterministic (e.g., selection) and stochastic (e.g., dispersal) processes, and the relative influence of these two process types is hypothesized to alter the influence of ...

Phyllosphere bacterial and fungal communities vary with host species identity, plant traits and seasonality in a subtropical forest

Environmental Microbiome, 2022
Background Phyllosphere microbes play important roles in host plant performance and fitness. Recent studies have suggested that tropical and temperate forests harbor diverse phyllosphere bacterial and fungal communities and their assembly is driven by ...

Linking nutrient availability and community size to stochasticity in microbial community assembly. [PDF]

FEMS Microbiol Ecol
Abstract Both deterministic (e.g. species–environment interactions) and stochastic processes (e.g. random birth and death events) shape communities, but it remains poorly understood, which environmental conditions promote stochasticity.

Microbial community assembly and evolution in subseafloor sediment [PDF]

Proceedings of the National Academy of Sciences, 2017
Significance Our study shows that deep subseafloor sediments are populated by descendants of rare members of surface sediment microbial communities that become predominant during burial over thousands of years. We provide estimates of mutation rates and strength of purifying selection in a set of taxonomically diverse microbial populations in

Local environment, surface characteristics and stochastic processes shape the dynamics of urban dustbin surface microbiome

Environment International, 2023
Dustbins function as critical infrastructures for urban sanitation, creating a distinct breeding ground for microbial assemblages. However, there is no information regarding the dynamics of microbial communities and the underlying mechanism for community

Ecological landscapes guide the assembly of optimal microbial communities [PDF]

PLOS Computational Biology, 2021
AbstractAssembling optimal microbial communities is key for various applications in biofuel production, agriculture, and human health. Finding the optimal community is challenging because the number of possible communities grows exponentially with the number of species, and so an exhaustive search cannot be performed even for a dozen species.
