“…spatial dispersal), temporal turnover (i.e. ecological succession) and local environmental filtering are critical ecological processes that shape the regional and biogeographical co-occurrence patterns of soil fauna (Ainsworth et al, 2020;Lv et al, 2014;Suurkuukka et al, 2012;Wu & Wang, 2019). Therefore, scale dependency, including environmental and spatiotemporal trends continues to be of pivotal importance to conservation biogeography (Suurkuukka et al, 2012).…”

“…Nematodes are known to be present in all soil substrata, sediment types and in every climatic zone including the Antarctic (Barbuto and Zullini 2005). Since nematodes are numerically dominant in most soils and dominate meiofaunal communities in both lotic and lentic environments, they have been used in biomonitoring studies of aquatic habitats for several years (Coull and Palmer 1984;Bongers and Ferris 1999;Höss et al 2006;Lv et al 2014). They regulate the turnover of microbial communities (Ingham et al 1985;Coull 1999) and thus play an important role in ecosystem functioning (Ekschmitt et al 2001;Ferris et al 2001).…”

The nematofauna of the Seekoeivlei Wetland in the north-eastern Free State province of South Africa was studied in order to determine its ecological status. Nematodes were collected in three different surveys, in October 2011, and in February and May 2012. Samples were taken from three sites within the reserve, each representing a different habitat. A total of 37 genera belonging to 21 nematode families were identified. The highest nematode diversity was observed during the summer sampling survey. All trophic groups were represented in only two sites in February. Maturity index was lowest in February (MI 2-5 = 1.99) and highest in May (MI 2-5 = 3.25). Non-metric multidimensional scaling analysis showed separation of seasons with winter and spring being most different from each other, which was supported by ANOSIM (R = 0.704; p < 0.001). The nematode faunal analysis profile of most of the soil food webs per locality per survey clustered into quadrat C, demonstrating that overall the Seekoeivlei Wetland was undisturbed with moderate enrichment and represented by fungal decomposition pathways. This study was the first to use nematode community data solely to determine the ecological status of a wetland in South Africa, which may henceforth be used for reference purposes.

Sixteen polycyclic aromatic hydrocarbons (PAHs) were quantified by GC/MS in 30 soil samples of Liaohe estuarine reed wetland. The total concentrations of 16 PAHs ranged from 235 to 374 ng g, and seven carcinogenic PAHs concentrations were in the range of 83-109 ng g. A probabilistic carcinogenic potential for three age groups (including children, teenagers, and adults) exposed to soil PAHs via three pathways was quantitatively calculated based on Monte Carlo simulations. The 95th percentiles carcinogenic risks of PAHs for children, teenagers, and adults were 7.80 × 10, 4.03 × 10, and 1.14 × 10, respectively. The carcinogenic risk levels were all below 10, indicating no potential for cancer development. Dermal contact and accident ingestion of soil were the dominant exposure pathways to soil PAHs. BaP and DBahA were the major contributors to carcinogenic risk in this study. Sensitivity analysis demonstrated that exposure duration and PAH concentrations in soil were the key exposure parameters in calculating carcinogenic risk. Results from this study will provide valuable information for potential scientific evaluation and prevention for carcinogenic risk exposed to soil PAHs.
