Disturbance alters the forest soil microbiome
Molecular Ecology, 2021Abstract Billions of microorganisms perform critical below‐ground functions in all terrestrial ecosystems. While largely invisible to the naked eye, they support all higher lifeforms, form symbiotic relationships with ~90% of terrestrial plant species, stabilize soils, and facilitate biogeochemical cycles.

Assessment of disturbance on soil ecosystems
Veterinary Parasitology, 1993Given the complexity of ecosystems, the high degree of interactions among species, and the numerous responses of systems to disturbance, it is unlikely that simple assays developed for other systems would adequately serve to monitor soil systems. Apart from the questionable applicability of non-soil techniques, protocols to monitor soil biota in a ...

Sample Disturbance of Cemented Collapsible Soils
Journal of Geotechnical Engineering, 1991A comprehensive study of sample disturbance effects on the response of collapsible soils was performed. Block samples and various factors potentially affecting degree of disturbance were studied. It was found that the effect of tube length was statistically insignificant for lengths up to 305 mm for 71 mm diameter specimens, and likewise for sampler ...

Soil disturbance by soil animals on a topoclimatic gradient
European Journal of Soil Biology, 2004Abstract We measured the area and volume of soil disturbed by various groups of animals at three sites on a topoclimatic gradient in the Judean Desert, Israel. Both the area and volume of soil disturbed by animals correlated with the cumulative precipitation of the winter rain season.

Soil Disturbance and Soil Fragmentation During Tillage
2009Predicting the influence of a given tillage implement on a soil with given conditions is still an ambitious task in soil science. Although many research studies have been dealt with the subject in recent years only a few prediction models exist, mainly due to the complex interactions of implement geometry and soil conditions on soil failure and soil ...

Pedogenesis in disturbed alpine soils (NW Italy)
Geoderma, 2002In alpine environments, natural or man-induced disturbances are fairly common and acknowledged as determining factors in pedogenesis and soil distribution. We have selected a representative alpine valley in the Italian Northwestern Alps to evaluate the effects of perturbations of different intensity and frequency on soil development and weathering ...
