“…No signi cant difference in NaHCO 3 -Po (generally considered as easily mineralized OP) among the sites was observed. Moderate AP fractions including NaOH-Pi (binding with Fe and Al) and HCl-Pi (binding with Ca) linearly increased with the plantation age, possibly because of the slight increase in pH, which altered P solubility [44,47]. The forms of most OP generally include phytate, esters, and microbial biomass [48][49][50].…”

Revegetation by planting shrubs on moving sand dunes is widely used to control desertification in arid/semi-arid areas. The soil microbial community can gradually recover along with plantation development. The purposes of this study were (1) to investigate the responses of microbial communities involved in the mineralization of soil organic phosphorus (OP) and dissolution of inorganic P (IOP) to the development of sand-fixation plantation and (2) to discuss the interactions between P turnover microbial communities and soil properties. We detected the diversities of soil phoD gene (one of the Pho regulons encoding alkaline phosphomonoesterases) and gcd gene (encoding glucose dehydrogenase) and the compositions of phoD and gcd communities by using the high-throughput Illumina MiSeq sequencing technique in a chronosequence of Caragana microphylla plantations (0-, 10-, 20-, and 37-year plantations and a native C. microphylla shrub forest) in Horqin Sandy Land, northeast China. Soil properties including soil nutrients, enzymatic activity, and P fractions were also determined. The abundance of phoD and gcd genes linearly increased with the plantation age. However, the diversity of soil phoD microbes was more abundant than that of gcd. The phoD gene abundance and the fractions of total OP and IOP were positively correlated with the activity of phosphomonoesterase. Actinobacteria and Streptomycetaceae were absolutely dominant phoD taxa, while Proteobacteria and Rhizobiaceae were absolutely dominant gcd taxa. Plantation development facilitated the progressive successions of soil phoD and gcd communities resulting from the asymmetric increase in the abundance of dominant taxa. Soil total N, NH4-N, and available K were the main factors affecting the structures of phoD and gcd communities, while pH was not the main influencing factor in such arid and nutrient-poor sandy soil. Many phoD or gcd operational taxonomic units were classified into Rhizobium and Bradyrhizobium, suggesting the coupling relationship between soil P turnover and N fixation.

“…Soil P fractions were determined by using the sequential extraction method of Hedley et al (1982) with some modi cations [43][44]. Brie y, 0.5 g of soil was extracted by 30 mL of distilled water and then centrifuged at 3500 rpm for 16 min at 4 °C.…”

“…It has been found that the action of millipedes on leaf litter decreases the C/N ratio and improves some characteristics such as humidity and pH from acidic to neutral ( Ashwini and Sridhar, 2006 ). There is also evidence that these invertebrates and their microbiota as a whole positively affect soil aggregation, levels of nitrogen and labile phosphorus ( da Silva et al, 2017 ). The millipede gut is an ideal habitat for the development of symbiotic bacteria with enzymatic properties capable of cellulose and hemicellulose biodegradation ( Taylor, 1982 ; Guzev and Byzov, 2006 ; Ramanathan and Alagesan, 2012 ).…”

Recent reports indicate that the health of our planet is getting worse and that genuine transformative changes are pressing. So far, efforts to ameliorate Earth’s ecosystem crises have been insufficient, as these often depart from current knowledge of the underlying ecological processes. Nowadays, biodiversity loss and the alterations in biogeochemical cycles are reaching thresholds that put the survival of our species at risk. Biological interactions are fundamental for achieving biological conservation and restoration of ecological processes, especially those that contribute to nutrient cycles. Microorganism are recognized as key players in ecological interactions and nutrient cycling, both free-living and in symbiotic associations with multicellular organisms. This latter assemblage work as a functional ecological unit called “holobiont.” Here, we review the emergent ecosystem properties derived from holobionts, with special emphasis on detritivorous terrestrial arthropods and their symbiotic microorganisms. We revisit their relevance in the cycling of recalcitrant organic compounds (e.g., lignin and cellulose). Finally, based on the interconnection between biodiversity and nutrient cycling, we propose that a multicellular organism and its associates constitute an Ecosystem Holobiont (EH). This EH is the functional unit characterized by carrying out key ecosystem processes. We emphasize that in order to meet the challenge to restore the health of our planet it is critical to reduce anthropic pressures that may threaten not only individual entities (known as “bionts”) but also the stability of the associations that give rise to EH and their ecological functions.

Revegetation by planting shrubs on moving sand dunes is widely used to control desertification in arid/semi-arid areas. The soil including microbial community can gradually be improved along with plantation development. The purposes of this study were (1) to investigate the responses of microbial communities involved in the mineralization of soil organic phosphorus (OP) and dissolution of inorganic P (IOP) in the development of sand-fixating plantation and (2) to discuss the interactions between P turnover microbial communities and soil properties. We assessed the compositions of soil phoD gene (one of the Pho regulons encoding alkaline phosphomonoesterases) and gcd gene (encoding glucose dehydrogenase) in microbial community by using high-throughput Illumina MiSeq sequencing in a chronosequence of Caragana microphylla plantations (0-, 10-, 20-, and 37-year plantations and a native C. microphylla shrub forest) in Horqin Sandy Land, Northeast China. Soil properties including soil nutrients, enzymatic activity, and P fractions were also determined. The abundance of phoD and gcd genes linearly increased with the plantation age. However, the diversity of soil phoD microbes was more abundant than that of gcd. The phoD gene abundance and the fractions of total OP and IOP were positively correlated with the activity of phosphomonoesterase. Actinobacteria and Streptomycetaceae were the dominant phoD taxa, while Proteobacteria and Rhizobiaceae were the dominant gcd taxa. Plantation development facilitated the progressive successions of soil phoD and gcd communities resulting from the increase in the abundance of dominant taxa. Total soil N, NH4-N, and available K were the main factors affecting the structures of phoD and gcd communities, while pH was not significantly influencing factor in such arid and nutrient-poor sandy soil. Many phoD or gcd OTUs were classified into Rhizobium and Bradyrhizobium, suggesting the coupling relationship between soil P turnover and N fixation.
