High‐severity wildfire leads to multi‐decadal impacts on soil biogeochemistry in mixed‐conifer forests

During the past century, systematic wildfire suppression has decreased fire frequency and increased severity in western United States of America. While this resulted large ecological changes aboveground such as altered tree species composition forest density, little is known about long-term, belowground implications altered, ecologically novel, regimes, especially on soil biological processes. To better understand long-term high-severity fire, we used a 44-yr chronosequence Sierra Nevada where forests were historically adapted to frequent, low-severity but suppressed for at least 70 yr. High-severity (44 +yr) decrease (>50%, P < 0.05) extracellular enzyme activities, basal microbial respiration (56-72%, 0.05), organic carbon upper 5 cm compared sites that had not been burned 115 However, nitrogen (N) processes only affected most recent site (4 yr post-fire). Net nitrification by over 600% (P 0.001), returned similar levels unburned control 13-yr site. Contrary previous studies, did find consistent effect plant cover type biogeochemical mid-successional (10-50 yr) soils. Rather, reduction (C) quantity correlated positively with dampened C cycling Our results show drastic implication biogeochemistry underscore need experiments.

Alterations in soil pH emerge as a key driver of the impact of global change on soil microbial nitrogen cycling: Evidence from a global meta‐analysis

Global Ecology and Biogeography, Journal Year: 2022, Volume and Issue: 32(1), P. 145 - 165

Abstract Aim Soil nitrogen (N) cycling is critical to the productivity of terrestrial ecosystems. However, impact global change factors (GCFs) on microbial mediators N pathways has yet be synthesized, and it also remains unclear whether response abundance N‐cycling genes can predict changes in their corresponding processes. Location Global. Time period 2000–2021. Major taxa studied Archaea, bacteria. Methods We synthesized 8322 paired observations soil microorganisms related from field experiments which GCFs (climate nutrient addition) were manipulated. Results found that microbes most resistant elevated CO 2 , experimental warming water addition/reduction; however, addition combination with other significantly increased ammonia oxidizer bacteria ( amoA‐AOB ). The results indicated steady‐state (natural) conditions, main driving bacteria, archaea varied terms contributions climatic edaphic factors. upon manipulation GCFs, induced pH was essential factor associated genes. Notably, ammonia‐oxidizing amoA‐AOA ) genes, involved denitrification nirS nirK ), correlated rates processes, but GCF‐induced shifts potential nitrification rate (PNR) explained well by gene under GCFs. Main conclusions Our study highlights how ongoing might have a profound cycling. field‐based provide new insights into drivers
