Microbial ecology is the study of the interactions of microorganisms with their environment, each other, and plant and animal species. It includes the study of symbioses, biogeochemical cycles and the interaction of microbes with anthropogenic effects such as pollution and climate change.
The work proposes the concept of distinct micro-habitats within an intact soil matrix and describes composition and metabolic pathways of their bacterial inhabitants, as a first step towards a generalizable C processing-focused classification of soil micro-environmental conditions.
Microbial denitrification in rice paddy fields reduces N use efficiency. Here, the authors use field samples from major rice producing areas in China and identify microbial taxa involved in the metabolic couplings between aerobic CH4 oxidation and denitrification in rice paddy fields.
Here, by applying evolutionary genomics approaches to metagenomics data of lake microbiomes, the authors reveal that freshwater species with small genomes face extended periods with their niche adaptation capabilities frozen.
Challenges in obtaining empirical trait data hinder the development of trait-based frameworks for soil microbes. Here, the authors analyse traits of saprobic fungal isolates from a grassland site to propose a fungal economics spectrum, suggesting a general trait framework for soil fungi.
Prompt physiological reactivation after rainfall pulses may be key for microbial survival in arid ecosystems. Here, the authors use stable isotope tracers, single-cell NanoSIMS and metatranscriptomics to shed light on how desert biocrust microbial communities respond to rewetting.
In this study, Carrasco Flores et al. report that the bacterium Mycetocola lacteus protects the microalga Chlamydomonas reinhardtii from the antagonistic activity of Pseudomonas protegens.
Multidisciplinary culture-dependent and -independent techniques elucidate the unique microbial nitrogen cycle in nutrient-poor coastal Antarctica soils and reveal the contribution of novel key microbes to their nitrogen budget.
The clinical translation of therapeutics on the basis of human gut microorganisms is hampered by our limited knowledge of how microbes survive and adapt to fluctuating conditions in the gut. The systematic exploration of gut microbiome survival strategies and trade-offs will thus enable the design of more efficient microbiome-based interventions.
Metatranscriptomic data from more than 2,000 mosquitoes of 81 species show that the composition of mosquito viral communities is determined more by host phylogeny than by climate and land-use factors, which will help to inform arbovirus surveillance.
Characterizing bacterial responses to mixtures of chemical pollutants reveals interactive effects among pollutants. Our study highlights the predictability and resilience of microbial responses to complex mixtures of pollutants, offering the potential for improvements in ecotoxicological assessments.
