“…Forest management activities often modify soil and litter habitats [13][14][15], and these habitat changes often have significant effects on soil microarthropod assemblages. For example, clear-cutting affected populations and assemblage structure of litter microarthropods at Coweeta Hydrologic Laboratory for nearly a decade, with concomitant effects upon litter decomposition and soil nutrient dynamics [16][17][18]. Global climate change is expected to exert differential effects on decomposition rates by soil invertebrates, with forests in the Pacific Northwestern USA among those most likely to suffer negative consequences for the ecosystem services of soil arthropods [12].…”

Abstract:To assess effects of low-intensity fire, we combined two silvicultural prescriptions with prescribed fire in the California Cascade Range. In the first treatment, two 100-ha stands were thinned to reduce density while retaining old-growth structural characteristics, yielding residual stands with high structural diversity (HSD). Two other 100-ha plots were thinned to minimize old growth structure, producing even-aged stands of low structural diversity (LSD), and one 50-ha split-plot from each treatment was burned. In addition, two 50 ha old-growth Research Natural Areas (RNA) were selected as untreated reference plots, one of which was also burned. Fire treatments profoundly altered mite assemblages in the short term, and forest structure modification likely exacerbated that response. Sampling conducted two years following treatment confirmed a continuing decline in oribatid mite abundance. Oribatid species richness and assemblage heterogeneity also declined, and community dominance patterns were disrupted. Oribatid responses to fire were either more intense or began earlier in the LSD treatments, suggesting that removal of old-growth structure exacerbated mite responses to fire. Prostigmatids recovered quickly, but their populations nonetheless diminished significantly in burned split-plots. Mite assemblage responses to prescribed fire were continuing nearly two years later, with no clear evidence of recovery.

“…Algal masses accumulating over seagrass are likely to import fauna (Gore et al 1981) that are carried with the tumbling algae (Holmquist 1994). Mobile fauna may preferentially exploit sessile organisms damaged by disturbance (Sousa 1984): litter from terrestrial plant perturbations can enhance some arthropod communities (Santos & Whitford 1981, Seastedt & Crossley 1981, and seagrass litter is an important resource for some animals inhabiting seagrass (Fenchel 1970, Sogard et al 1987. My second objective was to test whether superimposition of algal structure over seagrass structure results in shifts in the faunal assemblage.…”

A field experiment was used to examine the interactions among structurally complex, spatially shifting structure (macroalgae deposited by currents), less-complex stationary structure (seagrass), and mobile benthic invertebrates. I tested the effect of drift algal patches on underlying seagrass structure and fauna by establishing manipulated algal mats over seagrass for comparison with control seagrass plots. Control and experimental plots did not differ significantly for any variable prior to algal addition, but most seagrass structure was removed by this disturbance over a 6 mo period. In contrast. abundance of mobile fauna on experimental plots increased after 6 mo of algal cover relative to abundance on control plots. There was also greater evenness in the canopy fauna of the algal plots which contrasted with the high level of dominance apparent on control plots. Although the structurally complex mats formed by drifting algae provided short-term habitat enhancement for some fauna, longterm effects on fauna are probably negative due to mat ephemerality and degradation of seagrass.

“…Bird and Chatarpaul (1986) also found a greater abundance of collembolans in a conventional forest harvest (where CWD are generally more abundant) than in a whole-tree harvest. In contrast, Huhta (1976), Seastedt and Crossley (1981), Blair and Crossley (1988), and Addison and Barber (1997) noted that collembolans abundance remained unchanged in the first few years after clearcutting. Our finding supports the observations of Addison and Barber (1997), that collembollans are responding positively to woody debris left on-site after harvest.…”

. Effects of two silvicultural practices on soil fauna abundance in a northern hardwood forest, Québec, Canada. Can. J. Soil Sci. 82: 105-113. Soil fauna play a key role in soil fertility and productivity of forest ecosystems and represent an important base of terrestrial food chains. The impact of forest management on soil fauna should be considered when sustainable forest management and conservation of biodiversity are desired. We evaluated the impact of selective cutting and strip clearcutting on soil fauna abundance in a northern hardwood forest of the Lower Laurentians of Québec. Twelve years after strip clearcutting, the abundance of carabid beetles (Coleoptera: Carabidae), collembolans (Hexapoda: Collembola) and snails (Stylommatophora: Sigmurethra) was greater in the strip clearcuts than the adjacent undisturbed strips. Snails and millipedes (Polydesmida: Polydesmidae) were more abundant in the selective cuts 6 to 8 yr after treatment. Spiders (Arachnida) were the only organism whose abundance was lower in the selective cuts than in the adjacent undisturbed forest. No significant negative effect of the silvicultural treatments was noted for the abundance of other caught organisms. This one-season sampling suggests there are few negative impacts associated with low intensity selective cutting and strip clearcutting on the abundance of soil fauna in this northern hardwood forest stands 6 to 12 yr after harvest. La faune du sol joue un rôle primordial en ce qui concerne la fertilité du sol et la productivité des écosystèmes forestiers et constitue un maillon important de la chaîne alimentaire terrestre. Les impacts des activités forestières sur les organismes du sol devraient donc être considérés dans un contexte d'aménagement forestier durable et de conservation de la biodiversité. Nous avons évalué l'impact de coupes de jardinage et de coupes totales par bandes sur l'abondance de la faune du sol dans une érablière des basses Laurentides de la région de Québec. Douze ans après la coupe totale par bandes, l'abondance des carabidés (Coleoptera: Carabidae), des collemboles (Hexapoda: Collembola) et des escargots (Stylommatophora: Sigmurethra) était plus élevée dans les bandes coupées comparativement aux bandes adjacentes non-perturbées. Les escargots et les millipèdes (Polydesmida: Polydesmidae) étaient plus abondants dans les forêts jardinées 6 à 8 ans après traitement comparativement à celles témoins. L'araignée (Arachnida) représentait le seul organisme dont l'abondance était plus faible dans les forêts jardinées comparées aux secteurs témoins. Aucun effet significatif des traitements sylvicoles n'a été décelé sur l'abondance des autres organismes capturés. Cette campagne d'échantillonnage d'une saison suggère que les coupes de jardinage de faible intensité et les coupes totales de faible superficie dans ce type de forêt engendre peu d'impacts négatifs sur l'abondance de la faune du sol 6 à 12 ans après les traitements.
