“…Nematodes were extracted by the cotton-wood filter method and identified to the genus or family level as described by Landi et al [ 17 ]. Soil nematode communities and their relationships with soil properties were investigated based on the following population parameters: (i) abundance of nematode taxa at the family level, (ii) ratio of obligate plant parasites (Pp) to bacterivores (B) and fungivores (F) (Pp/(B+F)) [ 27 ], (iii) maturity index [ 28 ] and the food web indicators (BI, basal index; EI, enrichment index; SI, structure index; CI, channel index) according to Ferris et al [ 14 ], (iv) diversity-weighted abundance based on nematode biomass (θ) and arranging soil nematode population on a functional basis into detritivores (bacterial and fungal feeders), plant-parasitic nematodes, and predators (including omnivores) [ 29 , 30 ], and (v) prey-to-predator θ mass ratio to evaluate regulation function [ 17 , 30 ].…”

“…Nematodes play a key role in the soil ecosystem because they occupy all consumer trophic levels of the soil food web [ 14 ]. In the framework of ecosystem services, free-living (bacterial and fungal feeders and their predators) and plant-parasitic nematodes are directly involved in the nutrient recycling of carbon, nitrogen, and phosphorus as supporting services [ 15 , 16 ] and in pest regulation services, respectively [ 17 ]. An efficient regulation of these services operated by predators, including the nematodes themselves, may be useful in reducing the input of synthetic pesticides which negatively affect soil fauna and, more generally, soil health [ 18 ].…”

“…Moreover, other authors state that the plant-parasitic nematodes are susceptible to agronomic practices such as green cover and irrigation [ 21 , 22 , 23 ]. Finally, soil compaction caused by tillage and harvesting machines could affect the soil nematode community [ 17 , 24 ].…”

The soil nematode community plays an important role in ecosystem services. The objective of this study was to assess the effect of Super-high density (SHD) olive orchards on the nematode community in five sites with different soils, climates, and cultivars. At each site, the SHD management system was compared to the adjacent olive orchard traditional (TRAD) system, in which the same soil management and phytosanitary measures were applied. Soil management was assessed by total organic carbon content (TOC), while the soil nematode community was evaluated using the nematode taxa abundances and soil nematode indicators. TOC was significantly decreased in the SHD olive orchard system compared to TRAD in the sites characterized by conventional tillage and mineral fertilization. The two-way ANOSIM analysis on nematode abundance showed no difference between the two olive management methods, instead showing only a significant difference per site mainly due to variabilities in plant-parasitic nematode assemblage. However, a negative impact of SHD management was evident in environments stressed by summer droughts and conventional tillage: the ratio of obligate plant-parasites to bacterivores and fungivores (Pp/(B+F)) was significantly higher in SHD than in the TRAD olive orchard system, and the prey-to-predator θ mass ratio showed the lowest values in the sites under organic fertilization or green manure. The canonical correspondence analysis showed that the free-living nematodes were only slightly affected by SHD olive orchards; instead, the presence of plant-parasitic nematodes families such as Telotylenchidae, Paratylenchidae, Meloidogynidae, and Criconematidae was favored, in comparison to Longidoridae, Heteroderidae, and Pratylenchidae.

“…Banyaknya nematoda parasit tumbuhan yang ditemukan di daerah ini merupakan dampak dari pengelolaan lahan agroforestri oleh masyarakat (Godefroid et al 2017). Menurut Landi et al (2018), pergantian jenis tanaman juga berpengaruh pada struktur komunitas nematoda pada suatu daerah, hal ini sesuai dengan penelitian Franco-Navarro dan Godinez-Vidal (2017) yang menyebutkan bahwa nematoda parasit tumbuhan lebih dominan pada lahan agroforestri. Kondisi vegetasi di Blok Pemanfaatan HPKT Tahura WAR pada arboretum satu, arboretum dua, arboretum tiga dan arboretum empat dideskripsikan pada Tabel 1.…”

Change of land forest in Wan Abdul Rachman Forest Park became agroforestry, affect of cover condition and decrease the content of soil matter. Nematode was one of the soils biotas that can be used as an indicator of change in the soil status. The aim of study is to know the community and diversity of nematodes on the Utilization Block, Integrated Educational Conservation Forest, Wan Abdul Rachman Great Forest Park. The research was conducted in April to May 2018. The soil samples were taken on arboretum one, arboretum two, arboretum three and arboretum four in Integrated Educational Conservation Forest, Wan Abdul Rachman Great Forest Park. Nematode observations were conducted in the Plant Pests Laboratory, Faculty of Agriculture, University of Lampung. Nematodes was identified to genus level based on morphological traits. The analysis used were including the index of diversity, dominance and similarities between genus arboretum. The results showed that there were 30 genus of nematode consists of 19 plant parasitic nematode genera, six nematoda bacterial-feeding, three nematode fungal-feeding and two predator nematodes. The dominant nematode genera were Criconomella, Helycotylenchulus and Rotylenchulus. The abundance of nematodes ranges from 171-617 individuals/300cm3 soil. The diversity of soil nematodes based on the Shannon-Wienner index ranges from 2,47 – 2,80. The Shannon-Whienner Index criteria were classified as moderate. The Simpson Index ranges from 0,89 – 0,93. The highest similarity index genus in arboretum three and four with a value of 0,81 and the lowest in arboretum two and three which is 0,54. Key words: nematodes community, Integrated Educational Conservation Forest, Wan Abdul Rachman Great Forest Park

“…In the east of Inner Mongolia, mowing can produce hay as a sellable commodity for livestock feeding (Zhang et al, 2017). In some regions, mowing was also used to remove grazing selection effects on plant growth, and to manage grass growth (Landi et al, 2018). Mowing has been postulated to reduce the negative effects of nitrogen deposition on plant abundance and richness by removing biomass to reduce excess nutrients in the ecosystem (Härdtle et al, 2006;Lepš, 2014).…”

Soil nematodes are the most numerous components of the soil fauna in terrestrial ecosystems. The occurrence and abundance of nematode trophic groups determine the structure and function of soil food webs. However, little is known about how nitrogen deposition and land-use practice (e.g. mowing) affect soil nematode communities. We investigated the main and interactive effects of nitrogen addition and mowing on soil nematode diversity and biomass carbon in nematode trophic groups in a temperate steppe in northern China. Nitrogen addition and mowing significantly decreased the abundance of soil nematodes and trophic diversity but had no effects on nematode richness and the Shannon-Wiener diversity. Nitrogen addition influenced soil nematode communities through decreasing soil pH. Mowing influenced soil nematode communities through decreasing soil moisture. Nitrogen addition enhanced the bacterial energy channel but mowing promoted fungal energy channel in the soil micro-food web. Our study emphasizes that ecosystem function supported by soil organisms can be greatly influenced by nitrogen deposition, and mowing cannot mitigate the negative effects of nitrogen deposition on soil food webs.
