However, it is not known, to what extent and representatives of which taxa may help reintegrating carbon from crop residues back into soil without triggering massive carbon release into the atmosphere. To tackle this problem, we conducted a three-month-long microcosm experiment with 21 different species of macrofauna (each treatment replicated four times) belonging to 13 families to test their ability to degrade wheat straw. Simultaneously CO₂ release from the microcosms was measured. Five species did not survive under experimental conditions. Among the remaining 16 species, three significantly increased wheat straw decomposition with <em>Oryctes nasicornis</em> larvae having inflicted the highest straw mass loss (64%) in comparison with the control, where no animals were added (29%). None of the tested species increased cumulative CO₂ evolution from the microcosms, while two species significantly reduced it. The reduction of carbon loss with aerobic respiration was recorded for <em>Cetonia aurata</em> larvae and the earthworm <em>Dendrobaena veneta</em> (respectively 2.5 and 2-fold in relation to the control – 53.8±4.6 mg CO₂-C g⁻¹ soil dry weight during the entire experiment). The original integrative Carbon Sequestration Index by Macrofauna (CSIM) calculated for both of the measured parameters suggests that the woodlouse <em>Armadillidium vulgare</em> and to a smaller extent the earthworm <em>D. veneta</em> appear to be the most promising organisms for industrial climate-friendly organic waste recycling in terms of survival, straw processing and simultaneous reduction of CO₂ emissions from soil. Our results proved that the engagement of saprophagous macrofauna in crop residue decomposition is a viable technique of carbon reincorporation into the soil. It is accompanied with CO₂ release mitigation into the atmosphere.</p></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":"104 ","pages":"Article 150958"},"PeriodicalIF":2.3,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140191001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a pipe of polyvinyl chloride (PVC) with a six-way connector, which was filled with soil plus AM fungal inoculum (<em>Funneliformis mosseae</em>, <em>Rhizophagus intraradices, Gigaspora gigantea</em> or non-inoculated -control-).

Four experimental units of each treatment were separated and collected at different times during the year: three were used to determine water-stable aggregates (disturbed soils), and one was preserved (undisturbed soil) to elaborate soil thin sections.

Thus, several programs of payment for ecosystem services have been developed in this biome focusing on revegetation of degraded areas. Forest regeneration promotes the development of soil invertebrate communities that play an important role in soil processes, delivering a wide range of ecosystem services. We studied the changes in macrofauna communities in three forests under different regeneration stages and the relationship between these invertebrates and soil chemical and physical properties. Macrofauna and soil chemical and physical properties were sampled until 30 cm depth in three forest fragments of the Brazilian Atlantic Forest under different regeneration stages: young regenerating forest (∼8 years old), secondary forest in intermediate regeneration stage (∼20 years old) and native secondary forest fragment. No significant differences in saturated hydraulic conductivity (K_s) were observed among sites, however, the old native forest showed reduction in K_s in deeper layers compared to young regenerating forests. Several macrofauna taxa were positively correlated with K_s and soil carbon. The stage of regeneration modified the abundance and diversity of these invertebrates in general (except for earthworms), and the old native forest showed high abundance of most taxa. In conclusion, our study highlights the potential of macrofauna communities as robust indicators of soil functions re-establishment in regenerating forests within the Atlantic Forest biome. The observed positive correlations between macrofauna abundance and diversity with soil water infiltration and organic carbon content emphasize the key role of these invertebrates to essential ecosystem functions.</p></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":"103 ","pages":"Article 150944"},"PeriodicalIF":2.3,"publicationDate":"2024-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139665905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, there is a need to better understand how particular environmental variables might alter the response of AM fungal communities. Here, we analysed data from a DNA-based survey of fungal communities in soils collected throughout Australia to observe relationships among soil nitrogen and phosphorus availability and the abundance of two AM fungal taxa that reportedly vary in function – the Gigasporaceae (putatively more important for nutrient uptake) and Glomeraceae (putatively more important for biotic stress). Relationships were assessed in three vegetation types – grasslands, forests and woodlands – to assess whether associations with soil nutrition varied depending on carbon availability for AM fungi. Fungi from the Gigasporaceae decreased in frequency as available phosphorus increased, while those from the Glomeraceae increased or were unresponsive as available phosphorus increased. Similar patterns were observed for nitrate availability, although only in woodlands. These patterns are consistent with expectations that AM fungi from the Gigasporaceae, in general, are better suited to alleviate nutrient limitation in hosts as soil chemical fertility decreases. This knowledge may aid in implementing optimal strategies involving AM fungal inoculum best suited to the local conditions of future land management and agricultural projects.</p></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":"103 ","pages":"Article 150934"},"PeriodicalIF":2.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0031405624009053/pdfft?md5=6a8bfda8325e42716bfca31ade938dbe&pid=1-s2.0-S0031405624009053-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139556465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rhizosphere, tuberosphere and bulk soil was collected from two field grown potato varieties. Bacterial communities were characterized by 16S rRNA gene amplicon sequencing. Bacterial organosulfur mobilization indicators were evaluated with cultivation dependent and independent methods and were correlated (Spearman) with the relative abundance of bacterial families.

Relative abundance of specific bacterial families were distinct between bulk soil, tuberosphere and rhizosphere. Tuberospheres had a tendency for higher arylsulfonate utilization compared to bulk soil. The families <em>Sphingomonadaceae, Sphingobacteriaceae</em> and <em>Rhizobiaceae</em> which presented a decline in their relative abundances from the rhizosphere to tuberosphere and bulk soil had positive correlations with organosulfur mobilizing indicators.
