Front Microbiol 2024; 15:1312286. [PMID: 38414777 PMCID: PMC10896735 DOI: 10.3389/fmicb.2024.1312286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 01/25/2024] [Indexed: 02/29/2024] Open
Abstract
Over the past decades, many forests have been converted to monoculture plantations, which might affect the soil microbial communities that are responsible for governing the soil biogeochemical processes. Understanding how reforestation efforts alter soil prokaryotic microbial communities will therefore inform forest management. In this study, the prokaryotic communities were comparatively investigated in a secondary Chinese fir forest (original) and a reforested Chinese fir plantation (reforested from a secondary Chinese fir forest) in Southern China. The results showed that reforestation changed the structure of the prokaryotic community: the relative abundances of important prokaryotic families in soil. This might be caused by the altered soil pH and organic matter content after reforestation. Soil profile layer depth was an important factor as the upper layers had a higher diversity of prokaryotes than the lower ones (p < 0.05). The composition of the prokaryotic community presented a seasonality characteristic. In addition, the results showed that the dominant phylum was Acidobacteria (58.86%) with Koribacteraceae (15.38%) as the dominant family in the secondary Chinese fir forest and the reforested plantation. Furthermore, soil organic matter, total N, hydrolyzable N, and NH 4 + - N were positively correlated with prokaryotic diversity (p < 0.05). Also, organic matter and NO 3 - - N were positively correlated to prokaryotic abundance (p < 0.05). This study demonstrated that re-forest transformation altered soil properties, which lead to the changes in microbial composition. The changes in microbial community might in turn influence biogeochemical processes and the environmental variables. The study could contribute to forest management and policy-making.

Intraspecific more than interspecific diversity plays an important role on Inner Mongolia grassland ecosystem functions: A microcosm experiment. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 826:154134. [PMID: 35219658 DOI: 10.1016/j.scitotenv.2022.154134] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 02/21/2022] [Accepted: 02/21/2022] [Indexed: 06/14/2023]
Abstract
Biodiversity changes in terrestrial communities continue in the context of global changes. However, the interactive effects of the changes in diversity at inter- and intraspecific levels as well as cascading effects from plant to soil microorganisms on ecosystem functioning under climate changes remains largely unexplored. Using grassland species in the semi-arid Inner Mongolia Steppe, we conducted a microcosm experiment to assess how drought treatment (non-drought and drought conditions), species diversity (2, 4, and 7 species) and genotypic diversity of the dominant species Leymus chinensis (1, 3, and 6 genotypes) affected ecosystem functions directly or indirectly via regulating plant community functional structure [community-weighted mean (CWM) and functional dispersion (FDis)] and soil microbial diversity (Shannon-Wiener index). Drought treatment, species and genotypic diversity significantly and interactively affected soil N, P cycle and soil multifunctionality as well as soil microbial diversity. Drought treatment significantly affected biomass, soil C cycle, CWM and soil microbial diversity. Species diversity significantly affected soil N cycle, CWM and FDis, and genotypic diversity significantly affected all soil functions and soil microbial diversity. CWM regulated the responses of all ecosystem functions except soil N cycle to the changes in soil moisture and species diversity, which supports the mass ratio hypothesis. The cascading effect from genotypic diversity to soil microbial diversity was significant on belowground biomass but not on any of the other ecosystem functions observed in this study. These findings highlight the importance of genotypic diversity of the dominant species L. chinensis in affecting belowground ecosystem functioning as well as soil microbial diversity, which should not be ignored for grassland protection and management. This study provides further insights into biodiversity and ecosystem functioning mechanisms in semi-arid grasslands in the context of global climate changes.

Antonie van Leeuwenhoek 2020; 113:1213-1223. [PMID: 32468220 DOI: 10.1007/s10482-020-01428-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 05/12/2020] [Indexed: 10/24/2022]
Abstract
A Gram-negative, psychrophilic bacterium, designated strain GS1T, was isolated from a forest soil sample collected from the West Peak of Mt. Yushan, Yushan National Park, Taiwan. Cells grown in broth cultures were mostly non-motile and non-flagellated, whereas motile cells with monotrichous, subpolar flagella were also observed. The novel strain grew over a temperature range of 4-25 °C with optimum growth at 10-15 °C. It grew aerobically and was not capable of anaerobic growth by fermentation of D-glucose or other carbohydrates. Ubiquinone 8 was the predominant isoprenoid quinone. The major polar lipids comprised phosphatidylethanolamine, diphosphatidylglycerol and dimethylaminoethanol. Cellular fatty acids were dominated by C16:1ω7c (35.2%), C16:0 (19.5%), C18:1ω7c (18.8%) and C17:0ω7c cyclo (15.5%). The DNA G + C content was 49.2 mol% evaluated according to the genomic sequencing data. Strain GS1T shared more than 96.5% 16S rRNA gene sequence similarities with type strains of four Collimonas species (97.2-97.5%), three Glaciimonas species (97.3% for each of the three) and Oxalicibacterium solurbis (96.5%). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain GS1T formed a stable genus-level clade with type strains of species in the genus Glaciimonas in the family Oxalobacteraceae and GS1T was an outgroup with respect to these Glaciimonas species. Characteristically, strain GS1T could be easily distinguished from the recognised Glaciimonas species by exhibition of swimming motility with monotrichous, subpolar flagellum in some of the cells, ability to grow in NaCl at 2% but not at 3% and the distinguishable fatty acid profiles. On the basis of the polyphasic taxonomic data from this study, strain GS1T is considered to represent a novel species of the genus Glaciimonas, for which the name Glaciimonas soli sp. nov. is proposed. The type strain is GS1T (= JCM 33275T = BCRC 81091T).
