Fire history and frequency alter arbuscular mycorrhizal fungal traits, community dynamics, and symbioses

Jacob R. Hopkins, Kristian Harris, Alison Elizabeth Bennett

Fire is a common disturbance that structures terrestrial ecosystems. Since climate change models predict increases in fire frequency, it is important to study how changes in fire regime influence plant fuel–related above- and belowground ecosystem components. Due to their role in plant …

Extreme rainfall shifts the drivers of Zea mays yield across a tillage-intensity gradient

Exploring Bacterial Interactions Under the Stress Gradient Hypothesis in Response to Selenium Stress

Kristian J. Harris, Alison Elizabeth Bennett

The Stress Gradient Hypothesis (SGH) predicts that interspecific interactions shift from competition under low stress to facilitation under high stress. Historically, this framework has been extensively studied in plants, but its application to microbial communities remains underexplored. Here, we review literature to …

Fire Limits Soil Microbial Dispersal and Differentially Impacts Bacterial and Fungal Communities

Jacob R. Hopkins, Giuseppina Vizzari, Alison Elizabeth Bennett, Antonino Malacrinò

Fire is a globally pervasive force reshaping ecosystems, yet its influence on the ecological processes structuring soil microbiomes remains poorly understood. Using a meta-analysis of > 2600 amplicon sequencing samples across 19 global studies, we tested whether fire alters soil microbiome assembly …

Fire Frequency Driven Increases in Burn Heterogeneity Promote Microbial Beta Diversity: A Test of the Pyrodiversity‐Biodiversity Hypothesis

Jacob R. Hopkins, Alison Elizabeth Bennett, Thomas P. McKenna

Fire is a common ecological disturbance that structures terrestrial ecosystems and biological communities. The ability of fires to contribute to ecosystem heterogeneity has been termed pyrodiversity and has been directly linked to biodiversity (i.e., the pyrodiversity-biodiversity hypothesis). Since climate change models predict …

Selenium alters the gene content but not the taxonomic composition of the soil microbiome

Alison Elizabeth Bennett, Scott Kelsey, Casey M. Saup, Mike Wilkins et autres

BACKGROUND: Microbiomes, essential to ecosystem processes, face strong selective forces that can drive rapid evolutionary adaptation. However, our understanding of evolutionary processes within natural systems remains limited. We investigated evolution in response to naturally occurring selenium in soils of different geological parental …

Leveraging traits for insight into the fungal ecology of burned ecosystems

Jacob R. Hopkins, Alison Elizabeth Bennett

Abstract Fungi play key roles in the fire‐fuel feedbacks that structure ~40% of the Earth's terrestrial ecosystems, yet a general understanding of fungal responses to fire is lacking. While fire and associated stressor effects on fungi vary based on fire regime components …

Soil microbiota and herbivory drive the assembly of tomato plant-associated microbial communities through different mechanisms

Antonino Malacrinò, Alison Elizabeth Bennett

Plant-associated microbial communities are key to shaping many aspects of plant biology. In this study, we tested whether soil microbial communities and herbivory influence the bacterial community of tomato plants and whether their influence in different plant compartments is driven by microbial …
