Effects of fire and fire-induced changes in soil properties on post-burn soil respiration

This study examines how fire and soil property changes affect post-burn soil respiration in boreal forests, finding reduced respiration rates and altered carbon cycling patterns.

Soil carbon mineralization and microbial community dynamics in response to PyOM addition

This study investigates how PyOM addition affects soil carbon mineralization and microbial communities in a burned forest soil, finding differential mineralization rates and microbial responses based on PyOM temperature of origin.

Soil microaggregate bacterial communities following Amynthas tokioensis and Amynthas agrestis earthworm co-invasion

This study examines how co-invasion by Amynthas tokioensis and Amynthas agrestis earthworms affects soil bacterial communities in woodlands, finding mixed effects on community composition and assembly processes.

Tillage homogenizes soil bacterial communities in microaggregate fractions by facilitating dispersal

This study examines how tillage affects bacterial communities in soil microaggregate fractions, finding that tillage homogenizes these communities through dispersal effects.

An empirical approach to developing and testing a traits-based fire ecology framework for bacterial response to wildfires

The paper investigates how fire-adaptive strategies shape bacterial communities in boreal forest soils after wildfires, finding varying impacts over time and burn severity.

Resilience in soil bacterial communities of the boreal forest from one to five years after wildfire across a severity gradient

The paper examines soil bacterial community resilience five years post-wildfire across a severity gradient, finding increased similarity to unburned sites and persistent enrichment of specific taxa.

Disturbance by soil mixing decreases microbial richness and supports homogenizing community assembly processes

Soil mixing decreases bacterial richness and supports homogenizing community assembly processes by reducing diversity and increasing self-similarity among communities.

Short-interval reburns in the boreal forest alter soil bacterial communities, reflecting increased pH and poor conifer seedling establishment

This study examines how short-interval reburns in boreal forests affect soil bacterial communities, finding changes in composition but not richness, and identifying specific taxa associated with fire frequency.

Root carbon interaction with soil minerals is dynamic, leaving a legacy of microbially-derived residues

The paper investigates how plant-derived carbon interacts with soil minerals and microbial activity, finding that rhizosphere conditions shape the chemistry of mineral-associated organic matter.

Pyrolyzed substrates induce aromatic compound metabolism in the post-fire fungus, Pyronema domesticum

This study shows Pyronema domesticum can metabolize pyrolyzed organic material (PyOM) from wildfires, converting it to CO2 and contributing to carbon cycling in post-fire ecosystems.

Effects of physical, chemical, and biological ageing on the mineralization of pine wood biochar by a Streptomyces isolate

This study examines how physical, chemical, and biological ageing affects the mineralization of pine wood biochar by a Streptomyces isolate, finding that physical ageing increases carbon mineralization.

Standard and Non-Standard Measurements of Acidity and the Bacterial Ecology of Northern Temperate Mineral Soils

This study compares standard and non-standard soil pH measurements to assess their impact on predicting bacterial community composition in soil.

Microbial community shifts reflect losses of native soil carbon with pyrogenic and fresh organic matter additions and are greatest in low-carbon soils

The paper investigates how microbial community shifts in response to pyrogenic and fresh organic matter additions affect native soil carbon loss, finding greater impacts in low-carbon soils.

Soil Bacterial and Fungal Response to Wildfires in the Canadian Boreal Forest Across a Burn Severity Gradient

The paper examines how wildfires affect soil microbial communities in the Canadian boreal forest, finding that burn severity predicts microbial composition and identifies fire-responsive taxa.

Spatiotemporal Dynamics of the Bacterial Microbiota on Lacustrine Cladophora glomerata (Chlorophyta)

The paper analyzes bacterial epibiota on Cladophora glomerata across microsites and times, finding greater seasonal variation than microsite effects and identifying methanotrophic genera with inter-annual variability.

Microbial community assembly differs by mineral type in the rhizosphere

The paper investigates how microbial communities assemble on different soil minerals in the rhizosphere and finds that dispersal limitation and microbial growth capacity shape these communities.
