“…In the past several decades, the importance of soil nematodes in ecological monitoring and restoration assessment has been increasingly recognized [13,17,20,28]. However, although abandoning farmland for revegetation has been considered the principal land-use change on the Loess Plateau [31], its impact on soil nematode communities is seldom studied in this region.…”

“…To date, numerous studies have addressed the effects of revegetation on soil nematode communities [24][25][26]. Previous results showed that soil nematode communities typically varied by the specific revegetation approach [25,[27][28][29], and their characteristics provide a critical assessment of restoration in plant communities and soil food webs [21,30].…”

Soil nematode communities can offer valuable indicators for monitoring the status of soil ecosystems. However, their potential for assessing soil restoration under revegetation has been neglected in temperate arid and semiarid areas. This study examined the characteristics of soil nematode communities and their relationships with soil physicochemical properties under five typical revegetation approaches in the semiarid Loess Plateau of China. The results showed that planting an artificial Caragana korshinskii forest led to the recovery of the soil food web, which significantly increased soil nematode abundance (138.10 ± 11.60 inds./100 g dry soil) and community diversity (Shannon-Wiener diversity: 2.48 ± 0.13; trophic diversity: 3.08 ± 0.02), associated with the high contents of SOC and NH4+-N. However, establishing an artificial Prunus sibirica forest improved neither soil properties nor nematode community characteristics, reflecting poor soil ecosystem restoration. After establishing an artificial Prunus davidiana forest (PD) and an artificial Medicago sativa grassland (MS), substantial increases in herbivorous and fungivorous nematodes were observed, respectively, likely due to the accumulation of particular genera that fed on roots (e.g., Pratylenchus) or their symbiotic fungi (e.g., Tylencholaimus), which might result in the deterioration (in MS) or restoration (in PD) of the soil food webs. Natural grassland restoration greatly improved soil properties (i.e., SOC, NH4+-N, microbial biomass carbon) but did not change the nematode community obviously, probably due to top-down predation in natural habitats. In conclusion, the characteristics of nematode communities can effectively indicate the restoration of soil food webs and identify their possible driving forces under revegetation, which have important implications for vegetation restoration in arid and semiarid regions.

Impact of land use and management practices on soil nematode communities of Machair, a low-input calcareous ecosystem of conservation importance

Abstract: Land use and season were the main drivers of nematode communities from Machair soils.• Functionally, nematode communities from grassland were distinct. • Bacterial-feeding nematodes dominated all land uses.
