“…Third, the pronounced effect of the dispersal barriers indicates that the main mode of dispersal of oribatid mites and springtails was not transportation by wind or by water masses over the rock surface during rainfall, but instead active ground-based movement (walking or jumping), in agreement with earlier findings (Wanner and Dunger 2002;Dunger et al 2002). Although not a surprising conclusion, this is a prerequisite for using this system as a model for many general questions in landscape ecology.…”

Micro-arthropods in moss patches have been used as a model system to investigate the effects of habitat destruction and fragmentation on population viability and ecosystem functioning. Previous assessments of the sensitivity to fragmentation and the effectiveness of mitigating landscape structures have to some extent been contradictory, one possible reason being a lack of knowledge of the realised dispersal distances of the species involved. We investigated the dispersal capabilities of oribatid mites (Acari: Oribatida) and springtails (Collembola) in an experimentally fragmented system consisting of bryophytes on a bare rock surface. We used defaunated patches that were recolonized from populated patches nearby as well as from a mainland surrounding the experimental arena, during 10 weeks in summer. We measured within-mainland, mainland-to-island, and island-to-island dispersal, and found that: (1) Oribatid mites were severely dispersal limited within the time frame of the experiment, even at isolation distances of only 5 cm; (2) springtails did not show any dispersal limitation over distances as far as 300 cm; (3) despite the observed dispersal limitation, the mainland had a relatively large influence on microarthropod occurrence, even at 300 cm distance; and (4) the dispersal rates were high enough for both species sorting and-in the case of collembolans-mass effects processes to occur. Our results indicate that fragmentation can strongly influence species occurrence and abundance in natural systems that are limited by dispersal. They also show that the presence of a distant mainland can override the influence of nearby habitat patches on local diversity and abundance.

“…It might be that the relatively young soil collected at F1, made up of a thin and heterogeneous layer, is less preferred by F. quadriloculata, I. minor, F. inoculata. Indeed, these species tend to be more abundant in stable and homogenous substrates compared to Mesaphorura organisms, which are dominant in young substrates [58]. The low pH measured in F1 may also have favored the presence of Mesaphorura sp., as many species of Mesaphorura sp.…”

“…The reason for the scale-speciWc correlations between Collembola diversity and habitat heterogeneity is not apparent from these data. It might be, however, that while large-scale patterns in land use generate habitat structure that may, over time, aVect Collembola diversity by inXuencing passive population dispersal and diVerential persistence among patches of varying quality (Dunger et al 2002;Ettema and Wardle 2002;Ponge et al 2003Ponge et al , 2006Ims et al 2004), the local-scale employed here did not capture either those coarse-scale ecological processes (dispersal, patch dynamics) or the processes (competition, predation, facilitation) that occur on the microscale (i.e. centimetres) at which these small-bodied soil mesofauna operate (Ettema and Wardle 2002;Bardgett et al 2005).…”

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

Habitat heterogeneity contributes to the maintenance of diversity, but the extent that landscape-scale rather than local-scale heterogeneity influences the diversity of soil invertebrates-species with small range sizes-is less clear. Using a Scottish habitat heterogeneity gradient we correlated Collembola and lumbricid worm species richness and abundance with different elements (forest cover, habitat richness and patchiness) and qualities (plant species richness, soil variables) of habitat heterogeneity, at landscape (1 km(2)) and local (up to 200 m(2)) scales. Soil fauna assemblages showed considerable turnover in species composition along this habitat heterogeneity gradient. Soil fauna species richness and turnover was greatest in landscapes that were a mosaic of habitats. Soil fauna diversity was hump-shaped along a gradient of forest cover, peaking where there was a mixture of forest and open habitats in the landscape. Landscape-scale habitat richness was positively correlated with lumbricid diversity, while Collembola and lumbricid abundances were negatively and positively related to landscape spatial patchiness. Furthermore, soil fauna diversity was positively correlated with plant diversity, which in turn peaked in the sites that were a mosaic of forest and open habitat patches. There was less evidence that local-scale habitat variables (habitat richness, tree cover, plant species richness, litter cover, soil pH, depth of organic horizon) affected soil fauna diversity: Collembola diversity was independent of all these measures, while lumbricid diversity positively and negatively correlated with vascular plant species richness and tree canopy density. Landscape-scale habitat heterogeneity affects soil diversity regardless of taxon, while the influence of habitat heterogeneity at local scales is dependent on taxon identity, and hence ecological traits, e.g. body size. Landscape-scale habitat heterogeneity by providing different niches and refuges, together with passive dispersal and population patch dynamics, positively contributes to soil faunal diversity.
