A framework for integrating microbial dispersal modes into soil ecosystem ecology

IScience, 25(3), 103887.

By: M. Choudoir* & K. DeAngelis*

TL;DR: This work proposes the classification of microbial dispersal into three categories, through vegetative or active cells, through dormant cells, and through acellular dispersal, each with unique spatiotemporal dynamics and microbial trait associations that should improve the integration of dispersal in defining soil microbial community structure-function relationships.

Volatile organic compounds from leaf litter decomposition alter soil microbial communities and carbon dynamics

author keywords: ammonium; carbon cycle; carbon sequestration; microbial biomass; microbial diversity; mineral associated organic matter; nitrate; particulate organic matter; stable isotope probing; target gene sequencing; VOC
MeSH headings : Carbon; Microbiota; Plant Leaves; Soil; Soil Microbiology; Volatile Organic Compounds
TL;DR: This work used a 99-day microcosm experiment to track VOCs produced during microbial decomposition of 13 C-labeled leaf litter into soil carbon fractions where the decomposing litters were only sharing headspace with the soil samples, thus preventing direct contact and aqueous movement of litter carbon.

By: M. Choudoir*, C. Pepe-Ranney* & D. Buckley*

author keywords: Streptomyces; biogeography; comparative genomics; diversification; secondary metabolite biosynthetic gene clusters; SMGC; natural products
TL;DR: It is shown that changes in SMGC diversity between the sister-taxa were driven primarily by gene acquisition and deletion events, and these changes were associated with an overall change in genome size which accompanied lineage divergence. (via Semantic Scholar)
