Transitory dynamic effects in the soil invertebrate community in a temperate deciduous forest: Effects of resource quality

Species-specific characteristics of trees can determine the litter macroinvertebrate community and decomposition process below their canopies

“…In both cases pseudoscorpions were least abundant under Q. laurina trees. This result is consistent with other studies that have found that pseudoscorpions remain unaffected by the addition of different qualities of organic matter resources to the forest floor (Salamon et al 2006).…”

Litter manipulation and the soil arthropod community in a lowland tropical rainforest

“…This suggests that resource availability does not limit arthropod populations in this lowland neotropical forest, which agrees with results obtained in temperate environments (Salamon et al, 2006). Given the importance of top-down processes that has been demonstrated in a tropical plant/herbivore ecosystem in Costa Rica (Letourneau and Dyer, 1998), it is possible that when resource availability is not limiting, tropical invertebrate populations are mediated from the top-down.…”

Scale-specific correlations between habitat heterogeneity and soil fauna diversity along a landscape structure gradient

“…DiVerences in which landscape elements inXuence diversity are often taxon-or functional-group-speciWc Chust et al 2004;Dauber et al 2005;Purtauf et al 2005); and here perhaps reXect the distinct ecological requirements of each taxon. The predominantly fungivorous Collembola depend on the presence of a relatively undisturbed plant detritus food web (Ponge et al 1993;Bardgett and Cook 1998;Hedlund and Ohrn 2000;Hopkin 2000) (but see Salamon et al 2006) of forest and no-tillage, low-intensity pasture ecosystems. Conversely, lumbricid worms are nearly absent from acidic forest soils, and have a reduced dependence on soil microbial communities as primary decomposers (Bardgett and Cook 1998;Maraun et al 2003;Bardgett et al 2005).…”

“…We studied with a Scottish habitat heterogeneity gradient, at landscape (1 km 2 ) and local (sampling point-up to 200 m 2 ) spatial scales, the inXuence of diVerent aspects of habitat heterogeneity-classiWed into "elements" (forest percentage cover, habitat richness and patchiness) or "qualities" (plant functional group diversity, litter cover, soil variables) based on Tews et al (2004)-on the species richness and abundance of two functionally dissimilar soil taxa (Collembola and lumbricid worms). Collembola are primarily fungal grazers dependent on the presence of a plant detritus food web common to forests and extensive grassland, while lumbricids consume organic matter directly-and hence are less dependent on soil microbes-and the majority of lumbricid species are intolerant of acidic forest soils (Hopkin 1997;Bardgett and Cook 1998;Bardgett et al 2005;Salamon et al 2006). Thus, it is possible that the diversity of these two taxa will be sensitive to diVerent qualities (e.g.…”
