Geology and elevation shape bacterial assembly in Antarctic endolithic communities

Science of The Total Environment
Ice free areas of continental Antarctica are among the coldest and driest environments on Earth, and yet, they support surprisingly diverse and highly adapted microbial communities. Endolithic growth is one of the key adaptations to such extreme environments and often represents the dominant life-form.

Environmental filtering: A case of bacterial community assembly in soil

Soil Biology and Biochemistry, 2019
Soil has a strong effect on the assembly of bacterial communities, as revealed by studies in which sterilized soil is inoculated with dilution series of bacterial suspensions from the same soil. However, the impact of soil on the assembly of bacterial communities after inoculation with suspensions from different soils is not clear.

Warming Promotes Deterministic Assembly of Bacterial and Fungal Communities in Drylands

Microbial Ecology
Warming is altering the functioning of desert ecosystems in global drylands. Microbial communities are crucial for maintaining these ecosystems, yet how their co-occurrence networks and assembly mechanisms respond to warming remains unclear. Using 16 S and ITS rRNA amplicon sequencing, we examined bacterial and fungal community composition and ...

Characterization of specificity of bacterial community structure within the burrow environment of the marine polychaete Hediste (Nereis) diversicolor [PDF]

, 2011
Bioturbation is known to stimulate microbial communities, especially in macrofaunal burrows where the abundance and activities of bacteria are increased.

Press Disturbance Alters Community Structure and Assembly Mechanisms of Bacterial Taxa and Functional Genes in Mesocosm-Scale Bioreactors

mSystems, 2020
Press disturbances are of interest in microbial ecology, as they can drive microbial communities to alternative stable states. However, the effect of press disturbances in community assembly mechanisms, particularly with regard to taxa and functional ...

Changes in assembly processes in soil bacterial communities following a wildfire disturbance [PDF]

The ISME Journal, 2013
Abstract Although recent work has shown that both deterministic and stochastic processes are important in structuring microbial communities, the factors that affect the relative contributions of niche and neutral processes are poorly understood.
