“…However, the higher abundance of Agr1 resulted from manure application. Research by Renčo et al (2020) also got the same result. The abundance of the bacterivore, fungivore, and herbivore groups has a positive correlation with soil moisture.…”

Soil biota is very diverse and contributes widely to ecosystem services that are important in the sustainable function of natural and managed ecosystems. Knowing the condition of the soil food web through the communities that inhabit it is necessary to assess the productivity of the soil. Nematode communities in the soil food web can be used as indicators because of their high abundance, and they inhabit various trophic levels, and participate in several important processes in the soil. The soil food web condition from three locations (Agr1, Agr2, Agr3) through the nematode functional index was evaluated using the maturity index (MI), the maturity index 2-5 (MI-25), the plant-parasitic index (PPI), the channel index (CI), the enrichment index (EI), the structure index (SI), and the basal index (BI). Nematode diversity was evaluated using Simpson’s index of diversity, dominance, and evenness. The MI and MI2-5 scores indicated that Agr3 (3.81) had an undisturbed food web, while Agr2 (2.88 and 3.0) and Agr1 (2.5 and 2.51) were in a moderate condition with minor disturbances. Fauna profile analysis using SI and EI shows that Agr3 and Agr1 had an undisturbed soil food web, and Agr2 was in enriched conditions. CI results found that Agr1 and Agr3 had a fungal decomposition pathway while Agr2 had a bacterial decomposition pathway. We concluded from this research, that prospect of the nematode community to serve as a collection of biological indicator data in assessing soil or ecosystem health can be considered in further research.

“…For instance, the level of soil compaction caused by heavy machinery during tree clear-cutting was more intense (data not shown) in the clay site (SOGB) than in the sandy site (SAPH), leading to significant consequences for soil nematodes (Shah et al 2017). Soil texture greatly affects the composition of soil nematodes at both global (van den Hoogen et al 2020) and local scales (Quist et al 2019), having a stronger impact on nematodes than climate or land management (Renčo et al 2020). Therefore, it is not surprising that texture or other physical soil properties modulate the response of nematodes over time following clear-cutting in rubber plantations.…”

Aims Tree logging in tropical tree plantations results in significant soil disturbances that negatively impact soil biodiversity and soil functioning. Here, we aimed to assess the effects of adding organic matter (OM) to soil after rubber tree logging on soil functioning over time. Methods The experiment was conducted in two contrasting soil types in Ivory Coast. Four practices were replicated, including a control with no residues, the presence of legumes only, legumes and all tree parts excluding the trunk, and legumes and all the parts of the tree including the trunk. We monitored the response of soil nematode communities every six months for 24 months in each practice. Samples were collected from the topsoil layer (0–10 cm) in the interrow, and we also monitored soil carbon transformation by measuring in situ basal soil respiration, labile soil carbon and organic matter decay using the bait lamina method. Results The results showed a sharp decrease in nematode abundance after tree logging, but OM restoration increased nematode abundance, the relative abundance of bacterivores, and resource availability to the soil food web. The resilience of the nematode communities depended on soil conditions and the amount and quality of logging residues. Total nematode abundance was positively and significantly related to soil functioning, measured through basal soil respiration, labile soil carbon, and organic matter decay rate. Conclusion The results suggest that restoring logging residues can be an effective way to restore soil biodiversity and mitigate the negative impact of clear-cutting in tropical rubber plantations.

Based on the study of the structural and functional organization of nematode communities of primary ecosystems, it is possible to determine the degree of transformation of secondary ecosystems, because anthropogenic activity leads to changes in their formation. Nematode communities of indigenous ecosystems have preserved their evolutionary-formed structural and functional organization and the ratio of trophic groups. This ensures the integrity and stability of biogeocenoses. Therefore, such groups have a significant bioindication role. The research was conducted within the Skolivski Beskydy National Nature Park. A mixed beech forest was selected as the reference plot. For two years, we have been taking samples of litter and soil under the spruce canopy. Nematodes were separated from the soil using the Berman method on a Kempson device. De Man indices were used to determine species. Based on the division of nematodes into trophic groups according to G. Yeats, we calculated the part of each of them in the litter and soil. The number of nematodes in the litter increases from the upper horizon to the humus. In freshly fallen leaves the variety of nematodes (horizon L) is the least. In 2014 and 2015 in the upper horizon of the litter at different times of the year, the number of phytonematodes varied from 22 to 28 %, in the enzymatic horizon from 30 to 35 %, and in the humus horizon from 38 to 47 % of the total number of phytonematodes. The three litter horizons have the largest number of omnivorous nematodes, which is about two-thirds of the total number of the community with the largest quantity in summer. The part of predatory nematodes in spring and autumn is about 10 %, and in summer increases to 15 %. Bacteriovorus nematodes make about 18 % in spring, 25 % in summer, and 22 % in autumn, with a predominance in the F-horizon of litter. The part of fungivorous nematodes in all horizons of litter is approximately 5 %, with a predominance of the total number of this trophic group in the enzyme horizon. Omnivorous nematodes are represented mainly by species of the genus Eudorylaimus and Aporcelaimellus, carnivorous nematodes belong to the genera Prionchulus, Iotonchus, Tripyla, and bacteriophages are dominated by nematodes of the genera Plectus and Acrobeloides, and the group of fungivorous is mainly represented by species of the genus Aphelenchoides. Our results were later used to compare changes in nematode communities in derived ecosystems.
