Microbial resistance and resilience in response to environmental changes under the higher intensity of human activities than global average level

Global Change Biology, Journal Year: 2020, Volume and Issue: 26(4), P. 2377 - 2389

Abstract With the increasing intensity of global human activities, ecosystem function, which is supported by microbial community, will be dramatically changed and impaired. To investigate resistance resilience communities to we chose two typical types disturbances, urbanization, reclamation under higher activities than average level. We examined traits, including abundance, diversity, phylogeny, co‐occurrence interactions in soil communities, together with nitrification observed subtropical coastal Pearl River Estuary microcosm experiments. Microbial were less resistant environmental changes caused urbanization those reclamation, was significantly reflected nitrogen and/or carbon‐related patterns. However, most traits could recovered almost original level without significant differences after 40 days incubation. The between nitrifiers other not completely recovered, but this change did affect their for balancing ammonium during recovery stage, suggesting that might have fewer effects on previously thought. This study quantitatively demonstrated as a whole can recover status similar state short time removal stress at large scale even ecosystems, implied strong capacity community intense disturbance.

Microbial drought resistance may destabilize soil carbon

Trends in Microbiology, Journal Year: 2023, Volume and Issue: 31(8), P. 780 - 787

Published: April 12, 2023

Droughts are becoming more frequent and intense with climate change. As plants microbes respond to drought, there may be consequences for the vast stocks of organic carbon stored in soils. If sustain their activity under soils could lose carbon, especially if inputs from decline. Empirical theoretical studies reveal multiple mechanisms microbial drought resistance, including tolerance avoidance. Physiological responses allow acclimate within minutes days. Along dispersal, shifts community composition microbiomes maintain functioning despite drought. Microbes might also adapt drier conditions through evolutionary processes. Together, these result soil losses larger than currently anticipated

Drought legacy interacts with wildfire to alter soil microbial communities in a Mediterranean climate-type forest

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 915, P. 170111 - 170111

Mediterranean forest ecosystems will be increasingly affected by hotter drought and more frequent severe wildfire events in the future. However, little is known about longer-term responses of these forests to multiple disturbances forests' capacity maintain ecosystem function. This particularly so for below-ground organisms, which have received less attention than those above-ground, despite their essential contributions We investigated rhizosphere microbial communities a resprouting Eucalyptus marginata forest, southwestern Australia, that had experienced four years previously, eight previously. Our aim was understand how are over trajectories wildfire, singularly, combination. Fungal bacterial DNA extracted from soil samples, amplified, subjected high throughput sequencing. Richness, diversity, composition, putative functional groups were then examined. found monotonic decrease fungal, but not bacterial, richness diversity with increasing disturbance greatest changes resulting combination wildfire.

Increased belowground tree carbon allocation in a mature mixed forest in a dry versus a wet year

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(2)

Published: Feb. 1, 2024

Abstract Tree species differ in their carbon (C) allocation strategies during environmental change. Disentangling species‐specific and contribution to the C balance of mixed forests requires observations at individual tree level. We measured a complete set pools fluxes level five species, conifers broadleaves, co‐existing mature evergreen Mediterranean forest. Our study period included drought year followed by an above‐average wet year, offering opportunity test effect water availability on allocation. found that comparison uptake was lower dry use same, belowground sinks higher. Among major sinks, respiration largest (ca. 60%), while root exudation 10%) reproduction 2%) were those increased most year. Most trees relied stored starch for maintaining stable soluble sugars balance, but no significant differences detected aboveground storage between years. The detailed tree‐level analysis nonstructural carbohydrates δ 13 dynamics suggest interspecific among tissues, specifically response varying availability. Overall, our findings shed light forest physiological responses drought, increasing phenomenon under ongoing climate
