{"title":"Herbivore Dung inputs mainly drive copiotrophic bacterial contributions to soil nutrient pool turnover in alpine grasslands","authors":"Zhiyang Zhang, Xin Jing, Steffen Kolb, Yi Jiao","doi":"10.1007/s00374-025-01959-5","DOIUrl":"https://doi.org/10.1007/s00374-025-01959-5","url":null,"abstract":"Herbivore dung deposition represents a fundamental ecological disturbance in grassland ecosystems, profoundly modulating biogeochemical processes such as nutrient pool dynamics. While short-term effects on specific nutrient processes is generally established, the long-term consequences of herbivore dung deposition on soil nutrient pool turnover in alpine grassland, particularly the interacting biotic and abiotic regulatory mechanisms, remains incomplete. To bridge this knowledge gap, we established a three-year yak dung decomposition experiment in a permanently grazed alpine pasture on the Qinghai-Tibet Plateau, investigating how dung-induced alterations in bacterial communities and some critical soil parameters (including pH, moisture content, and enzymatic activities) collectively regulate nutrient pool turnover in alpine grassland soils. Results showed that dung deposition substantially accelerates soil nutrient cycling, with peak turnover occurring during the early and middle decomposition phases. Concurrently, dung deposition elevated the soil pH and moisture content and enhanced the enzymatic activities integral to the nutrient turnovers, including β-1,4-glucosidase, β-1,4-xylosidase, L-leucine aminopeptidase, acid phosphatase, and oxidase activities, as well as increased the diversity (Shannon index) and altered the composition of bacterial communities. Bacterial communities, moisture content, enzymatic activities, and pH collectively regulate nutrient pool turnover, with bacterial communities exerting the strongest influence among these factors. Notably, dung deposition significantly enriched bacterial lineages, particularly <jats:italic>Pseudomonadota</jats:italic> , <jats:italic>Bacteroidota</jats:italic> , and <jats:italic>Bacillota</jats:italic> , along with their dominant subgroups (e.g., <jats:italic>Alphaproteobacteria</jats:italic> ‌, <jats:italic>Gammaproteobacteria</jats:italic> , <jats:italic>Bacteroidia</jats:italic> , and <jats:italic>Bacilli</jats:italic> ), which emerged as the primary copiotrophic microbial drivers of nutrient pool turnover in response to dung inputs. Together, these findings from our full-lifecycle in situ experiment demonstrate that herbivore dung deposition accelerates alpine grassland soil nutrient cycling predominantly by stimulating copiotrophic bacterial activity. This integrated perspective advances our understanding of how escalating herbivore activity may reshape biogeochemical cycling in grazed alpine ecosystems, with implications for sustainable grassland management and carbon sequestration strategies.","PeriodicalId":9210,"journal":{"name":"Biology and Fertility of Soils","volume":"150 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145403941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is unclear how root morphology in interaction with soil texture affects microbial traits and the storage of organic matter in soil. To address this gap, two maize genotypes differing in the presence of root hairs (the root hair deficient mutant <jats:italic>rth3</jats:italic> and its corresponding wild type) were grown in monoculture for five consecutive years in excavated plots filled with two homogenised substrates (loam and sand). In the fifth year of maize monoculture, soil was sampled during plant growth in summer and after six months of winter fallow after harvest. We found slower microbial growth and lower microbial C accumulation in summer with <jats:italic>rth3</jats:italic> grown in loam compared to wild-type plants. We also observed increased soil organic C and total N contents in loam after winter fallow of <jats:italic>rth3</jats:italic> compared to the wild type. This was accompanied by a higher relative abundance of carboxylic acids, lignin, primary amides and ester groups in the former. In sand, retarded microbial growth and lower microbial C content were observed compared to the loam. In conclusion, heterotrophic microorganisms appear to play a crucial role in the accumulation of soil organic matter during winter, when there is no input of fresh labile molecules from active roots. It is therefore essential to implement agricultural practices that facilitate these processes.","PeriodicalId":9210,"journal":{"name":"Biology and Fertility of Soils","volume":"110 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145382219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many field and laboratory studies investigate the effect of plant residue (e.g., straw) on soil bacterial communities after a period of time. However, whether aged plant residue will exert an interfering impact remains unanswered. Here, five air-dried soils were mixed with 5 g kg⁻¹ rice straw and then stored at room temperature (~ 25 ℃), -20 ℃, or -80 ℃. At all three temperatures, we found that compared to the unamended control soils, plant residue had a minor effect (&lt; 10%) on bacterial abundance and no significant effect on bacterial community composition after 4 and 10 weeks. However, for two air-dried soils (soils 4 and 5), we observed a significant increase in bacterial abundance and a shift in bacterial community composition after storage for 4 and 10 weeks, compared to week 0, at all three temperatures. These findings stood when we repeated the experiment with a rice straw addition rate at 20 g kg⁻¹. Many of the phylotypes that increased after storage in soils 4 and 5, which had the highest pH and lowest nutrient contents in all soils, are reportedly tolerant to dry, alkaline, or oligotrophic conditions. Metagenomic analysis further showed that genes related to bacterial drought, cold, and alkali resistance increased in soils 4 and 5 after storage. These results suggest that aged plant residue does not affect bacterial communities in air-dried soils but for alkaline and oligotrophic air-dried soils, storage may do even at -80 ℃. This work can help us optimize the storage of soils for microbial analysis and understand microorganism survival in dry soils.</p>","PeriodicalId":9210,"journal":{"name":"Biology and Fertility of Soils","volume":"19 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144930648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, we still have limited understanding of how specific microbes contribute to HFA. Here, we examined how variation in HFA relates to differences in soil bacterial diversity and interconnections among co-existing bacteria taxa. A 480-d reciprocal transplant experiment was designed using <i>Schima superba</i> and <i>Zea mays</i> litter collected from forest and farmland ecosystems, respectively. Our findings showed that litter decomposition is associated with specific soil bacterial taxa that generate HFA effects for litter use. The decomposition of labile <i>Z. mays</i> litter in away site increased the biodiversity of soil bacteria, thereby creating more complex and stable co-occurrence networks. In contrast, the decomposition of recalcitrant <i>S. superba</i> litter in away site reduced the interconnections among co-existing taxa by preventing the establishment of specific taxa such as Proteobacteria and Actinobacteria, resulting in less complex and stable networks. The simplified bacterial networks in away sites led to reduced ecosystem functions, including nutrient cycling and decomposition, and were responsible for the generation of HFA in litter decomposition. Furthermore, the effect of soil bacterial diversity on litter mass loss was indirectly driven by network stability, suggesting that interconnections among co-existing taxa enable a better explanation how specific microbes contribute to drive HFA than the diversity metrics. Our results highlight the importance of co-occurrence networks as a key component of microbial biodiversity linking it with litter decomposition.</p>","PeriodicalId":9210,"journal":{"name":"Biology and Fertility of Soils","volume":"56 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we focus on the physiological and biochemical effects of Al toxicity on plants, as well as the mechanisms of plant resistance to Al toxicity. We particularly emphasize the interaction between plants and microorganisms, and how microbes could be used to enhance plant tolerance to Al toxicity. Notably, microbial inoculation strategies often face challenges due to the soil properties and competitive exclusion by indigenous soil microbiomes. Despite these challenges, we propose that combining omics techniques with synthetic microbial consortia designed for Al stress may be a more effective approach to addressing the related issues in this research area.

An on-field drought simulation experiment using rain-out shelters was conducted as part of a long-term field experiment cultivated with winter wheat, comparing cropping systems with contrasting fertilization strategies and crop protection measures: A biodynamic system and a mixed conventional system with no pesticide application, and a purely minerally fertilized conventional system, with conventional pesticide use. The implemented drought lasted for three months, starting at plant tillering stage and ending at ripening stage. No watering was performed on the drought treatment during that period. Soils were sampled at stem elongation, flowering, and ripening. EPS-carbohydrates and EPS-proteins significantly increased by approximately 20% due to induced drought but remained roughly constant from stem elongation to ripening under drought. Mean EPS-carbohydrates to EPS-proteins ratio was 1.9. MBC and MBN remained largely unaffected by drought. The ratio of both EPS fractions to microbial biomass was lowest in the biodynamic system and highest in the minerally fertilized conventional system, indicating that rhizodeposits and mucilage were predominantly diverted into microbial biomass, rather than into microbial EPS.
