“…Warming and altered precipitation regimes are two further potential features of global change that can have a severe impact on soil fauna since temperature and water availability directly regulate soil organisms activity, metabolism and community composition (Nielsen & Ball, 2015;Tan et al, 2021). For example warming may increase soil fauna density directly, by boosting their development and reproduction and indirectly via a rise in food supply due to increased litter input and microbial activity (Guo et al, 2021;Mueller et al, 2016). Water availability seriously affects the activity and reproduction of soil fauna, as well as the taxonomic composition of its communities, whereas increased or decreased precipitation frequencies usually have the opposite effect (Guo et al, 2021).…”

“…Furthermore, most available research has focused on the effects of individual GCFs and the combined effects of multiple GCFs have rarely ever been addressed (Rillig et al, 2019), despite the fact that the occurrence of multiple GCFs is widespread and that greater numbers of simultaneously changing GCFs will result in ever-more changes in soil properties, processes and communities (Rillig et al, 2019). For example, although warming tends to have positive effects for soil fauna communities (Guo et al, 2021), it can also induce warming-associated droughts that will have negative effects (Lindberg et al, 2002), which ensures that the responses of soil fauna to warming are complex and difficult to predict. Single-factor studies are critical for understanding mechanisms but we also need to take into account all the drivers of global change if we are to truly improve our capacity to forecast.…”

Responses of soil fauna communities to the individual and combined effects of multiple global change factors

Soil fauna plays a key role in regulating biogeochemical cycles, but how multiple global change factors (GCFs) may affect faunal communities remains poorly studied. We conducted a meta‐analysis using 1154 observations to evaluate the individual and combined effects of elevated CO2, nitrogen (N) addition, warming, increased rainfall and drought on soil fauna density and diversity. Here we show that, overall, individual and combined effects of GCFs had negligible effects on soil fauna density and diversity, except that density was negatively affected by drought (−27.4%) and positively affected by increased rainfall individually (+24.9%) and in combination with N addition (+67.3%) or warming (+70.4%). GCF effects varied among taxonomic groups both in magnitude and direction. Variables such as latitude, elevation and experimental setting significantly impacted both individual and combined effects. Our results suggest that soil fauna density is affected by changed rainfall regimes, while diversity is resistant against individual and combined effects of multiple GCFs.

“…Amongst the abiotic factors, temperature, humidity and precipitation pattern potentially influence the survival, development and behavior of the soil-inhabiting PPNs ( Norton, 1979 ). Alike other parasites and pathogens, the warm and humid climate favors quick development, higher reproduction, increased period of transmission, altered sex ratio, spatiotemporal shift in abundance and diversity of both the plant-parasitic and free-living nematodes ( Neilson and Boag, 1996 ; Yeates and Newton, 2009 ; Maleita et al., 2012 ; Wu et al., 2016 ; St-Marseille et al., 2019 ; Guo et al., 2021 ; Klusmann et al., 2022 ). The micro-parasitic abundance in an agroecosystem is directly linked to the degree of host damage and economic loss of the crops.…”

Pest profiles in today’s global food production system are continually affected by climate change and extreme weather. Under varying climatic conditions, plant-parasitic nematodes (PPNs) cause substantial economic damage to a wide variety of agricultural and horticultural commodities. In parallel, their herbivory also accredit to diverse ecosystem services such as nutrient cycling, allocation and turnover of plant biomass, shaping of vegetation community, and alteration of rhizospheric microorganism consortium by modifying the root exudation pattern. Thus PPNs, together with the vast majority of free-living nematodes, act as ecological drivers. Because of direct exposure to the open environment, PPN biology and physiology are largely governed by environmental factors including temperature, precipitation, humidity, atmospheric and soil carbon dioxide level, and weather extremes. The negative effects of climate change such as global warming, elevated CO2, altered precipitation and the weather extremes including heat waves, droughts, floods, wildfires and storms greatly influence the biogeographic range, distribution, abundance, survival, fitness, reproduction, and parasitic potential of the PPNs. Changes in these biological and ecological parameters associated to the PPNs exert huge impact on agriculture. Yet, depending on how adaptable the species are according to their geo-spatial distribution, the consequences of climate change include both positive and negative effects on the PPN communities. While assorting the effects of climate change as a whole, it can be estimated that the changing environmental factors, on one hand, will aggravate the PPN damage by aiding to abundance, distribution, reproduction, generation, plant growth and reduced plant defense, but the phenomena like sex reversal, entering cryptobiosis, and reduced survival should act in counter direction. This seemingly creates a contraposition effect, where assessing any confluent trend is difficult. However, as the climate change effects will differ according to space and time it is apprehensible that the PPNs will react and adapt according to their location and species specificity. Nevertheless, the bio-ecological shifts in the PPNs will necessitate tweaking their management practices from the agri-horticultural perspective. In this regard, we must aim for a ‘climate-smart’ package that will take care of the food production, pest prevention and environment protection. Integrated nematode management involving precise monitoring and modeling-based studies of population dynamics in relation to climatic fluctuations with escalated reliance on biocontrol, host resistance, and other safer approaches like crop rotation, crop scheduling, cover cropping, biofumigation, use of farmyard manure (FYM) would surely prove to be viable options. Although the novel nematicidal molecules are target-specific and relatively less harmful to the environment, their application should not be promoted following the global aim to reduce pesticide usage in future agriculture. Thus, having a reliable risk assessment with scenario planning, the adaptive management strategies must be designed to cope with the impending situation and satisfy the farmers’ need.

“…Numerous studies have demonstrated that global warming can directly or indirectly affect the soil nematode community [5]. For example, it was reported that global warming altered the soil nematode community structure and reduced the nematode community abundance and composition in the agricultural and grass ecosystems [9,10]. However, in the desert ecosystem, the warming effect was not observed [11].…”

Both global warming and alien plant invasion can affect the biotic communities in the soil. Most studies are focused on the soil microbial community, but little is known about how global warming, along with alien plant invasion, affects the diversity and function of the soil nematode community. In this study, the individual and interactive effects of experimental warming and Canada goldenrod (Solidago canadensis L.) invasion on soil nematode communities were measured. Experimental air warming, in combination with different levels of S. canadensis invasion, were applied. The results showed that S. canadensis invasion significantly increased chao1, maturity, and structure indexes of the nematode community by 31.44%, 25.57%, and 329.3%, respectively, and decreased the basal index by 48.70% (all p < 0.05). Only the Simpson index was affected by the interaction between warming and S. canadensis invasion. Warming enhanced the S. canadensis invasion effect on the soil nematode community. The changes in nematode community were correlated with shifts in nutrient availability and resource stoichiometry, as well as microbes in the soil. These findings demonstrated that global warming and S. canadensis invasion may, directly and indirectly, alter the soil nematode community, which may considerably affect the functioning of underground food webs.
