While the importance of soil fauna is well recognized, quantitative estimates of the role of soil fauna on soil biogeochemical processes, such as plant litter decomposition, are limited by methodological constraints. The addition of naphthalene, a polycyclic aromatic hydrocarbon (C10H8), to suppress soil fauna has been used for decades in decomposition experiments, but its efficacy remains questioned. In fact, we lack a rigorous field assessment of the efficacy of naphthalene additions for soil fauna suppression and potential non-target effects on the soil microbial community and carbon cycling. We added naphthalene at a high rate (477 g m&minus;2) monthly for 23 months on the bare soil surface of a tallgrass prairie. We determined the effect of such additions on the abundance of nematodes and micro-arthropods along the soil profile to a depth of 20 cm at 11, 16 and 23 months after initiating naphthalene application. We used the variation in the natural 13C abundance of the naphthalene (δ13C &ndash; 25.5&permil;) as compared to the native soil (δ13C &sim; &minus;17&permil;) to quantify naphthalene contribution to soil CO2 efflux and microbial biomarkers (PLFA). Naphthalene addition significantly reduced the abundance of oribatid mites (&minus;45%), predatory mites (&minus;52%) and springtails (&minus;49%), but did not affect nematode abundance. The 13C abundance of a few Gram-negative (cy17:0, 18:1ω7c, 16:1ω7c), Gram-positive (a15:0, i15:0) and Actinobacteria (10Me-16:0, 10Me-18:0) PLFA markers decreased significantly in naphthalene treated plots, indicating bacterial utilization of naphthalene-derived C. Mixing models showed this contribution to be highly variable, with the highest naphthalene-C incorporation for Gram negative bacteria. Naphthalene-C was not incorporated in fungal PLFAs. This microbial utilization did not affect overall microbial abundance, community structure or activity, estimated as soil respiration. This experiment proves that naphthalene addition is a feasible method to reduce soil micro-arthropods in the field, with negligible direct effects on soil nematodes, microbial abundance and C dynamics.</p>10aFauna manipulation methods10aMites10aNematodes10aPLFA10aSpringtails10aStable C isotopes1 aCotrufo, M.F.1 aSoong, J.1 aVandegehuchte, M.L.1 aNgryen, T.1 aDenef, K.1 aShaw, E.A.1 aSylvain, Z.A.1 aTomasel, C.M.D.1 aNielsen, U.N.1 aWall, D.H.  uhttps://www.sciencedirect.com/science/article/pii/S0929139313002400?via%3Dihub02351nas a2200145   4500008004100000245009500041210006900136300001500205490000700220520181800227100001502045700001502060700001502075856011502090       2006                        eng d00aAre soil mite assemblages structured by the identity of native and invasive alien grasses?0 aAre soil mite assemblages structured by the identity of native a  a1314 -13240 v873 aAssociations between plants and animals in aboveground communities are often predictable and specific. This has been exploited for the purposes of estimating the diversity of animal species based on the diversity of plant species. The introduction of invasive alien plants into an ecosystem can result in dramatic changes in both the native plant and animal assemblages. Few data exist at the species level to determine whether belowground animal assemblages share the same degree of association to plants.

The hypotheses that soil mites (Acari) form assemblages specifically associated with different native grass species in an unmanipulated natural ecosystem and that invasive alien grasses will impact soil mite assemblage composition in this setting were tested. Soil mites sampled beneath five native and two invasive alien species of grasses at the Konza Prairie Biological Station, Kansas, USA, were similarly abundant, species rich, diverse, and taxonomically distinct. No mite species had affinities for a specific grass species. There was no evidence from analysis of similarity, canonical correspondence analysis, or a nonparametric assemblage analysis that the assemblage composition of soil mites was specific to grass species. Results suggest that soil mite assemblages were more related to characteristics of the plant assemblage as a whole or prevailing soil conditions. The most recent invasive alien grass did not support a successionally younger mite fauna, based on the ratio of mesostigmatid to oribatid mites, and neither of the two invasive grasses influenced mite assemblage structure, possibly because they had not yet substantially altered the soil environment. Our results suggest that extrapolations of soil mite diversity based on assumptions of plant specificity would be invalid.1 aJohn, M.G.1 aWall, D.H.1 aHunt, H.W.  uhttp://knz.lternet.edu/content/are-soil-mite-assemblages-structured-identity-native-and-invasive-alien-grasses02138nas a2200145   4500008004100000245006800041210006600109300001300175490000700188520164300195100001501838700001501853700002601868856009801894       2006                        eng d00aDoes plant species co-occurrence influence soil mite diversity?0 aDoes plant species cooccurrence influence soil mite diversity  a625 -6330 v873 aFew studies have considered whether plant taxa can be used as predictors of belowground faunal diversity in natural ecosystems. We examined soil mite (Acari) diversity beneath six grass species at the Konza Prairie Biological Station, Kansas, USA. We tested the hypotheses that soil mite species richness, abundance, and taxonomic diversity are greater (1) beneath grasses in dicultures (different species) compared to monocultures (same species), (2) beneath grasses of higher resource quality (lower C:N) compared to lower resource quality, and (3) beneath heterogeneous mixes of grasses (C3 and C4 grasses growing together) compared to homogeneous mixes (C3 or C4 grasses) using natural occurrences of plant species as treatments. This study is the first to examine the interaction between above- and belowground diversity in a natural setting with species-level resolution of a hyper-diverse taxon.

Our results indicate that grasses in diculture supported a more species and phylogenetically rich soil mite fauna than was observed for monocultures and that this relationship was significant at depth but not in the upper soil horizon. We noted that mite species richness was not linearly related to grass species richness, which suggests that simple extrapolations of soil faunal diversity based on plant species inventories may underestimate the richness of associated soil mite communities. The distribution of mite size classes in dicultures was considerably different than those for monocultures. There was no difference in soil mite richness between grass combinations of differing resource quality, or resource heterogeneity.1 aJohn, M.G.1 aWall, D.H.1 aBehan-Pelletier, V.M.  uhttp://knz.lternet.edu/content/does-plant-species-co-occurrence-influence-soil-mite-diversity02412nas a2200193   4500008004100000245009900041210006900140300001300209490000700222520174500229100002101974700001901995700001702014700001502031700001802046700001902064700001502083856012002098       2003                        eng d00aRelationships at the aboveground-belowground interface: Plants, soil biota, and soil processes0 aRelationships at the abovegroundbelowground interface Plants soi  a377 -3950 v733 aInteractions at the aboveground–belowground interface provide important feedbacks that regulate ecosystem processes. Organisms within soil food webs are involved in processes of decomposition and nutrient mineralization, and their abundance and activity have been linked to plant ecophysiological traits such as species identity and the quality and quantity of plant tissue. We tested aboveground–belowground diversity relationships in a naturally developed plant community of native tallgrass prairie by taking soil samples from beneath naturally established grass tillers of chosen characteristics (e.g., homogeneous vs. heterogeneous plant combinations or C4 vs. C3 photosynthetic pathway) without imposing any disturbances to existing plant–soil relationships. The goal of this study was to elucidate the consequences, for soil microbiota (microflora phospholipid fatty acids, protozoa, and nematode functional groups) and for C and N mineralization, of plant community properties such as species richness, resource quality, resource heterogeneity, species identity, and presence of exotics. None of the biotic or abiotic soil variables was related to plant resource heterogeneity. Protozoa were not responsive to any of the plant community traits. Some bacterial and nematode groups were affected by plant characteristics specific to a particular plant species, but no uniform pattern emerged. Invasive and native plants generally were similar with respect to soil variables tested in this study. The lack of clear responses of soil variables to plant community traits indicates that idiosyncratic effects dominate both at the plant and soil biotic level and that generalized plant and soil diversity effects are hard to predict.1 aPorazinska, D.L.1 aBardgett, R.D.1 aBlaauw, M.B.1 aHunt, H.W.1 aParsons, A.N.1 aSeastedt, T.R.1 aWall, D.H.  uhttp://knz.lternet.edu/content/relationships-aboveground-belowground-interface-plants-soil-biota-and-soil-processes01482nas a2200313   4500008004100000245004900041210004800090300001300138490000800151520065800159100001600817700002000833700001500853700002400868700001500892700001600907700001600923700001600939700001400955700001400969700001600983700001500999700001501014700001301029700002201042700001501064700001301079856007601092       2001                        eng d00aEcological forecasts: an emerging imperative0 aEcological forecasts an emerging imperative  a657 -6600 v2933 aPlanning and decision-making can be improved by access to reliable forecasts of ecosystem state, ecosystem services, and natural capital.
