We expected drought to reduce the activity of soil organisms and fertilization to induce positive bottom-up effects via increased plant productivity. Furthermore, we hypothesized fertilization to reinforce drought effects through enhanced plant growth, resulting in even drier soil conditions.

We conducted a microcosm experiment using two common endogeic earthworm species (Apor-rectodea caliginosa and Octolasion tyrtaeum) and two different soils (one from a beech-dominated forest and one from a mixed tree species forest in Germany) to test litter quality (different nutrient concentrations) and soil quality effects (low and high) on relative mass gain of earthworms. We hypothesized that mass gain of endogeic earthworms is driven by both soil and litter quality. Soil pH, carbon (C) and nitrogen (N) concentrations were used to characterize soil quality, while leaf litter N, phosphorus (P), calcium (Ca), and magnesium (Mg) concentrations were used as proxies for leaf litter quality. Forest soils were incubated with leaf litter of six common tree species in Central Europe (Fagus sylvatica, Acer platanoides, Acer pseudoplatanus, Carpinus betulus, Tilia spp., and Fraxinus excelsior) that span a gradient in leaf litter quality. In addition, we determined soil microbial biomass C as a potential food source of endogeic earthworms. After three months, relative earthworm mass gain of A. caliginosa and 0. tyrtaeum was significantly higher in soil from the mixed tree species forest (high quality soil: +218% and +240%, respectively) compared to soil from the beech-dominated forest (low quality soil: +160% and +162%, respectively). Relative mass gain of A. caliginosa increased significantly with all leaf litter nutrients in low quality soil, whereas in high quality soil only leaf litter Ca positively affected relative mass gain. Similarly, relative mass gain of O. tyrtaeum increased significantly with increasing concentrations of leaf litter N, Mg, and Ca in the low quality soil. In the high quality soil, only leaf litter Mg significantly increased relative mass gain. Overall, our results indicate that leaf litter quality effects on endogeic earthworm mass gain were more important in low quality soil for both earthworm species. Notably, microbial biomass was significantly higher in high quality soil (506 +/- 135 mu g C g(-1) soil dw) compared to low quality soil (217 +/- 64 mu g C g(-1) soil dw), but microbial biomass was not significantly affected by leaf litter type and was a poor predictor of relative earthworm mass gain. This finding indicates that endogeic earthworms did not significantly depend on soil microbial biomass, but rather on the quality of dead organic material in the soil and surface leaf litter. As earthworms may prefer feeding on certain microbial taxa, and we only measured total soil microbial biomass, future studies could investigate if leaf litter quality effects on earthworms are mediated by changes in soil microbial community structure, micronutrients, and organic compounds.

Despite the increasing appreciation that the consequences of impending global change can be better understood if varying agents are studied in concert, there is a paucity of multi-factor long-term studies, particularly on belowground processes. Herein, we address this gap by examining the responses of soil food webs and biodiversity to enrichment of CO2, elevated N, and summer drought in a long-term grassland study at Cedar Creek, Minnesota, USA (BioCON experiment). We use structural equation modeling (SEM), various abiotic and biotic explanatory variables, and data on soil microorganisms, protozoa, nematodes, and soil microarthropods to identify the impacts of multiple global change effects on drivers belowground. We found that long-term (13-year) changes in CO2 and N availability resulted in modest alterations of soil biotic food webs and biodiversity via several mechanisms, encompassing soil water availability, plant productivity, and most importantly changes in rhizodeposition. Four years of manipulation of summer drought exerted surprisingly minor effects, only detrimentally affecting belowground herbivores and ciliate protists at elevated N. Elevated CO2 increased microbial biomass and the density of ciliates, microarthropod detritivores, and gamasid mites, most likely by fueling soil food webs with labile C. Moreover, beneficial bottom-up effects of elevated CO2 compensated for detrimental elevated N effects on soil microarthropod taxa richness. In contrast, nematode taxa richness was lowest at elevated CO2 and elevated N. Thus, enrichment of atmospheric CO2 concentrations and N deposition may result in taxonomically and functionally altered, potentially simplified, soil communities. Detrimental effects of N deposition on soil biodiversity underscore recent reports on plant community simplification.

He concludes that a broader spectrum of approaches considering both non-random gains and losses of diversity is essential to advance this field of research. Wardle's paper is timely because of recent observations of frequent local and regional biodiversity changes across ecosystems. While we appreciate that new and complementary experimental approaches are required for advancing the field, we question criticisms regarding the validity of BEE experiments, Therefore, we respond by briefly reiterating previous arguments emphasizing the reasoning behind random species composition in REF experiments. We describe how BEE experiments have identified important mechanisms that play a role in real world ecosystems, advancing our understanding of ecosystem responses to species gains and losses.

Our overarching hypothesis is that ecosystem functioning increases when more plant species associate with functionally dissimilar mycorrhizal fungi because differing mycorrhizal types will increase coverage of habitat space for and reduce competition among plants. We introduce a recently established field experiment (MyDiv) that uses different pools of tree species that associate with either arbuscular or ectomycorrhizal fungi to create orthogonal experimental gradients in tree species richness and mycorrhizal associations and present initial results.

Belowground food webs drive soil C dynamics, but little is known about their responses to co-occurring global change agents. We investigated open-air experimental grassland communities at ambient and elevated atmospheric CO2 concentration, ambient and enriched nitrogen input, and ambient and reduced summer precipitation to evaluate how these agents interactively affect soil nematodes, which are often used as an indicator group for soil food web structure and soil health. The aim of the study was to elucidate the response of the functional diversity of soil nematodes to changing environmental conditions by using nematode functional guilds and indices as indicators. The results suggest that nematode functional guilds surpass nematode trophic groups as soil indicators, suggesting that more detailed data on nematode community structure is essential to capture functional changes in response to environmental change. For instance, the density of opportunistic fungal feeders increased due to N addition with the response being more pronounced at elevated CO2, whereas densities of sensitive fungal-feeders were increased at ambient N and elevated CO2, illustrating opposing responses within one trophic group. Opportunistic bacterial feeders increased at elevated N, but did not respond to other environmental factors studied. Root-feeding Longidoridae were significantly reduced at elevated CO2 and elevated N compared to ambient conditions, whereas other plant feeders were little affected by the manipulations. Predacious nematodes were less abundant at elevated N, and the Structure Index (which indicates food web structure) suggested reduced top-down forces and simplified soil food webs, although omnivores did not vary significantly. Elevated CO2 buffered the effect of reduced precipitation on the Enrichment Index (which indicates increased resource availability) and the Channel Index (which indicates changes in decomposition channel) probably due to reduced stomatal conductance at elevated CO2. Further, the results suggest that the decomposer community switched from a bacterial-dominated to a fungal-dominated system at elevated N, indicating shifts in the microbial community as well as in the functioning of belowground food webs. Overall, the studied global change agents interactively and differentially affected functional guilds of soil nematodes, suggesting complex changes in soil processes. We highlight that detailed information on the functional guilds of nematodes is likely necessary to fully understand alterations in soil food webs and related processes due to global environmental change.
