“…Accordingly, less organic matter has been found in the upper organo-mineral horizons (A) of the ski-slopes compared to the grasslands, suggesting either a lower organic matter accumulation, due to a lower biomass production in the ski-slope soil, or a stronger dilution of the former soil organic matter caused by mixing mineral and organo-mineral horizons during the ski-slope construction process. These results are in keeping with those reported in previous papers (Freppaz et al 2002;Gros et al 2004;Barni et al 2007;Pintar et al 2009;Pohl et al 2009;Martin et al 2010;Roux-Fouillet et al 2011). Moreover, most of the soil properties in both the ski-pistes and in the grasslands seemed to be closely related to elevation.…”

“…soil, vegetation and animals. Studies on the impact of ski-pistes have mostly been concentrated on soils (Freppaz et al 2002;Gros et al 2004;Pintar et al 2009 ), and on vegetation (Delarze 1994;Van Ommeren 2001;Wipf et al 2005), or, more rarely, on the combination of soil and vegetation (Barni et al 2007;Pohl et al 2009;Martin et al 2010;RouxFouillet et al 2011). The studies conducted on animals have not considered soil, and have only taken into account vegetation marginally (Laiolo and Rolando 2005;Rolando et al 2007;Caprio et al 2011;Negro et al 2009Negro et al , 2010Negro et al , 2013Rolando et al 2013).…”

Differential responses of ground dwelling arthropods to ski-piste restoration by hydroseeding

The construction of ski-pistes can cause serious damage to all the components of an ecosystem and may therefore be considered as one of the main causes of human-driven environmental changes in mountain habitats. This study was aimed at assessing the responses of different ground dwelling arthropod assemblages (i.e. ground beetles, spiders and grasshoppers) to ski-piste restoration through hydroseeding with commercial seed mixtures. The soil, vegetation and arthropods of restored and un-restored ski-pistes and the adjacent grassland have been sampled at two high altitude sites in the north-western Italian Alps. The ski-piste soil was characterized by a higher skeletal content and, consequently, a lower amount of fine earth and organic matter than that of the undisturbed adjacent grassland. The plant cover of the restored ski-pistes was very low above 2500 m a.s.l.; the vegetation cover below this threshold was higher in the study area, mainly due to the seeded species. The unrestored ski-pistes showed very large proportions of bare ground. The responses of the three ground-dwelling arthropod groups to vegetation conditions were different. GLMMs and IndVal analyses showed that all three groups avoided the unrestored skipistes plots, which were characterized by a very scarce vegetation cover, irrespective of the altitude. The low altitude plots of the restored ski-pistes, which were characterized by a high vegetation cover, had a significantly larger number of grasshoppers on the ski-pistes than on the adjacent grassland plots. Moreover, these restored ski-piste plots were used in equal proportion to the adjacent grassland plots by ground beetles but avoided by spiders. When ski-pistes become sufficiently revegetated by hydroseeded plants, they are colonized by grasshoppers and, to a lesser extent, by ground-beetles. Spiders, instead, do not colonize the pistes, thus demonstrating that they are the most sensitive arthropods and may therefore represent the best indicators of human-driven environmental changes in high altitude alpine habitats.

“…For example, a positive correlation between plant diversity and soil erosion has frequently been observed; however, a negative correlation has also been found (Turnbull et al, 2008). After conducting research in the Netherlands, Martin et al (2010) found that different vegetation conditions give rise to different correlations between plant diversity and soil erosion. Whether the correlation between plant diversity and soil erosion is positive or negative largely depends on the local environment.…”

Vegetation effectively prevents soil erosion. However the relationship between plant diversity and soil erosion remains ambiguous under various environmental conditions. To explore the role that plant diversity plays in soil erosion, this study was conducted in the Three-River-Source region, located in the hinterlands of the Qinghai-Tibet Plateau, China. After examining 99 plots within the study area, and analyzing the soil 137 Cs inventory within the plots, we found that with a greater number of plants distributed within an aggregation pattern, there was greater interception of the soil particles by the vegetation patch. This phenomenon results in a more developed vegetation patch that can support greater vegetation coverage and higher plant diversity than it previously could. Although a positive correlation exists between plant diversity and vegetation coverage, the relationship between the extent of soil erosion and plant diversity is modulated by the vegetation pattern. When plants are distributed in a relatively homogeneous pattern, vegetation coverage decreases with increasing plant diversity, which leads to increased soil erosion. When plants are distributed between a homogenous and a heterogeneous pattern, no relationship is found between plant diversity and soil erosion. With a heterogeneous plant distribution, vegetation coverage increases with plant diversity, and soil erosion is inhibited under such conditions.

“…Splash cups filled with soil were saturated with distilled water. The samples were put under the rainfall simulator at an intensity of 360 mmh -1 (≈60 mmh ) [28]. The high intensity was to compensate for short falling distance of 0.4 m used when calibrating the rainfall simulator.…”

Soil properties are known to be influenced Soil Organic Matter (SOM) resident time. However, there is limited information on the interactive effects of SOM quality and soil moisture on SOC and Microbial Biomass Carbon (MBC) hence on soil losses. Therefore, this study investigated the effects of different organic matter and soil moisture in soils with low (<2%) initial SOC content on the SOC, MBC and soil loss with time of organic matter incorporation. Six soils were incubated for 34 weeks at 25°C after adding high quality (C/N=23) Vachellia karroo leaf litter and low quality (C/N=41) Zea mays stover. The effect of SOM quality and soil moisture on the SOC content, MBC and soil loss was significantly (P<0.05) the same within but varied across soils. Soils that were continuously wet lost more SOC than under alternating wet-dry moisture conditions. Microbial biomass carbon was controlled by the availability of organic matter and moist soil conditions. Low MBC values corresponded to high SOC and soil loss. Continuously wet soils with high sand particles promoted rapid loss of SOC compared to alternating wet-dry soils. Therefore, continuously wet sandy soils are likely to contribute more to the climate warming than alternating wet-dry soil moisture. In the wake of the climatic change, addition of OM in continuously wet soils need to be regulated but to reduce soil loss re-application of fresh OM has to be more frequent under continuously wet sandy soils than in alternating wet-dry moisture regimes.
