Nitrogen (N) is an important component of the forest soils and plays a pivotal role in ecosystem’s health, also broadleaf Moso bamboo ( Phyllostachys edulis ) forests. numerous functions production transformation soil organic matter (SOM) alterations soil’s physicochemical biological properties. Despite extensive research on properties microorganism diversity forests, we still know very little about N dynamics its significance or how various physical environmental variables influence physicochemical, dynamics, attributes. This article provides thorough overview forests changes processes by summarizing recent advances our knowledge microbial diversity, carbon (C) sink As are sensitive to change, even small change these ecosystems can alter overall dynamics. Here, dissect ecology provide insights into possibilities consequences future studies ecosystems.

On the phenology of soil organisms: Current knowledge and future steps

Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(4)

Published: April 1, 2023

Abstract Phenology is the study of timing periodic activities in biological life cycles. It describes an inherent component ecosystem dynamics, and shifts activity have been increasingly recognized as indicator global change. Although phenology mainly studied above ground, major processes, such decomposition, mineralization, nutrient cycling, are soil‐dependent. Therefore, soil organisms a crucial, but understudied, aspect terrestrial functioning. We performed systematic review 96 studies, which reported 228 phenological observations, to evaluate current knowledge microbial animal phenology. Despite increasing number reports, most research still concentrated few countries (centered Northern Hemisphere) taxa (microbiota), with significant gaps diverse regions globe (i.e., tropics) important (e.g., ants, termites, earthworms). Moreover, biotic predictors biodiversity species interactions) rarely considered possible drivers organisms' present recommendations for future based on evaluation geographical, taxonomic, methodologic trends that bias research. First, we highlight papers depict good practice, either regarding foci, methodological approaches, or results reporting. Then, discuss gaps, challenges, opportunities Overall, advocate focusing both highly ecosystems key organisms, while testing direct indirect effects loss climatic stressors, could increase our functioning enhance accuracy predictions depicting change whole.

Different responses of soil respiration and its components to nitrogen and phosphorus addition in a subtropical secondary forest

Forest Ecosystems, Journal Year: 2021, Volume and Issue: 8(1)

Published: June 8, 2021

Abstract Background Nitrogen (N) and phosphorus (P) deposition have largely affected soil respiration ( R s ) in forest ecosystems. However, few studies explored how N P individually or combination to influence its components (autotrophic respiration, a ; heterotrophic h ), especially highly P-limited subtropical forests. To address this question, we conducted field manipulation experiment with and/or addition 50-year-old secondary forest. Results We found that on average reduced , by 15.2%, 15%, 11.7%, respectively during 2-year study. had an inconsistent effect increasing 50.5% the first year but reducing 26.6% second year. Moreover, decreased 8.9%–30.9% 6.7%–15.6% across 2 years. In contrast, co-addition increased 1.9%, 7.9%, 2.1% experimental period. Though were significantly correlated temperature, their temperature sensitivities not changed fertilization. was predominantly regulated nitrogen availability (NH 4 + NO 3 − dissolved organic carbon (DOC), enzyme activities, while variation mainly attributable changes microbial community composition β-D-Cellubiosidase (CB) β-Xylosidase (XYL) activities. Conclusion Our findings highlight contrasting responses of against co-addition, which should be differentially considered biogeochemical models order improve prediction dynamics context enrichment terrestrial

Short-term nutrient addition improves soil organic carbon accumulation in tropical forest

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 6, 2025

Background and Aims: Highly weathered tropical forests are widely recognized as nitrogen (N)-rich phosphorus (P)-poor, the input of nutrienteffects soil carbon (C) cycling storage in these ecosystems. In topsoil, short-term nutrient additionmay not only effect organic C (SOC) pools directly, but also impact conversion process indirectly through altering microbial use efficiency (CUE). However, effects addition on accumulation mechanisms remain unclear. The aim this study was to clarify SOC responding addition. Methods: This conducted a one-year N P additions experiment forest Hainan, China. SOC, fractions (POC MAOC), biomass, enzyme activities, physicochemical properties at depths 0–10 cm, 10–20 cm 20–40 were measured. Results: results showed that increased (8.91–20.03%), POC (6.65–24.90%), MAOC (8.74–19.89%) topsoil (0–10 cm), whereas no significant changes occurred subsoil (20–40 cm). Pearson’s correlation analysis revealed litter biomass CUE significantly positively correlated with SOC. partial least squares-path model influences by characteristics. Conclusions:These suggested decreased activities. Such information could provide insight understand pool forest.
