“…The present study revealed strong effects by physical soil disturbance on AMF community composition and diversity and by nitrogen fertilisation within the soil disturbance treatment. Soil disturbance has previously been identified as a factor influencing AMF communities' composition in natural plant communities (Husband et al 2002;Sýkorová et al 2007b;Schnoor and Olsson 2010), as well as in agroecosystems in long-term experiments (Jansa et al 2002;Rosendahl 2008;Borriello et al 2012;Stockinger et al 2014). The negative effect of physical soil disturbance on plant root colonisation found here has been previously reported in heathland and forest, but not in an annual pasture (Jasper et al 1991).…”

“…Soil disturbance also affects abiotic properties of the soil like nutrient availability (Fraterrigo et al 2005) or soil moisture (Robertson et al 1993). Soil disturbance is also known to decrease plant species competition in grasslands (Wilson and Tilman 1993), creating new patches for plant colonisation (Grubb 1977) and for competition for light (De Cauwer et al 2006), resulting in an increase in plant biodiversity (Schnoor and Olsson 2010). Specific interactions have been reported between pairs of plant and fungal symbionts (Vandenkoornhuyse et al 2003;Scheublin et al 2007), and a decisive influence of AMF on plant communities was demonstrated (van der Heijden et al 1998(van der Heijden et al , 2003(van der Heijden et al , 2008.…”

Short-term effects of soil physical disturbance by ploughing and nitrogen and phosphate fertilisation on arbuscular mycorrhizal fungal (AMF) communities and on intraspecific populations of Rhizophagus irregularis in a buffer strip surrounded by arable fields were studied. Pre-grown Plantago lanceolata plantlets were transplanted into fertilised and/or ploughed experimental plots. After 3 months, the glomeromycotan communities in the roots of these trap plants were analysed using 454 pyrosequencing of a fragment of the RNA polymerase II gene (RPB1). Intraspecific populations of R. irregularis were studied by restriction fragment length polymorphism (RFLP) analysis of the mitochondrial large ribosomal subunit (mtLSU) gene. Soil disturbance significantly increased the diversity of species-level molecular taxa (MTs) and altered community structure, whilst fertilisation alone had no significant effect, unless coupled with ploughing. At the population level, the expected shift from genotypes of R. irregularis typically found in grasslands to those usually found in arable sites was only partially observed. In conclusion, in the short-term, physical soil disturbance, as well as nitrogen fertilisation when coupled with physical soil disturbance, affected AMF community and to a smaller extent population composition.

“…S; it stands for all the species in a plot; S is the number of species; N is the sum of the numbers of all species in a plot; ni is the number of ith species in a plot; c is the number of species that appear in both a plot and control area; a and b are the number of species that appear in the plot and the control, respectively. Previous studies have shown that human disturbance has little influence on, or even helps keep high diversity levels (as shown with increases in the SHDI after disturbance events) (Brown, Ernest, Parody, & Haskell, 2001;Schnoor & Olsson, 2010;Gourlet-Fleury et al, 2013). Consequently, the situation of vegetation recovery cannot be evaluated solely by SHDI.…”

a b s t r a c tPipeline construction has severe disturbance on local ecosystems, especially in arid and semi-arid regions. Vegetation recovery along the pipeline is crucial for ecosystem management and eco-environment restoration. In this study, three typical regions with different backgrounds and engineering characteristics in northwest China were selected to analyze vegetation recovery pattern after pipeline disturbance by using comparative analysis and RDA analysis. The results showed that vegetation condition in the zone 10 m from the pipeline was worse than construction area above the pipeline, and was identified as a key area in which vegetation restoration needs to occur. Rainfall and total sunshine duration were found to be key factors affecting vegetation recovery. Additionally, recovery duration also played important roles in vegetation recovery. The affecting factors can be divided into two categories: environmental factors; and, engineering factors. Environmental factors contribute more to the differences of vegetation in different regions, while the engineering factors may play a more important role in relation to vegetation recovery within a region. In general, the effects of pipeline construction on vegetation pattern were confined to 300 m from the pipeline based on this study. However, artificial measures may hasten the vegetation recovery process. This research could provide scientific guidance for ecological restoration and environmental management for the construction of linear projects.

“…For example, in the pine and mixed oak-pine forests studied here, ruderals cannot germinate as long as a thick layer of litter and humus covers the mineral soil. Those obstacles vanish wherever animals excavate soil and bury the original forest floor (Mayer et al 2004;Schnoor and Olsson 2010). Seeds of some species like Urtica dioica and Mycelis muralis are particularly adapted to such disturbance episodes.…”

This study examined the effects of burrow digging and habitation by the European badger (Meles meles) and the red fox (Vulpes vulpes) on soil properties and the plant community. The vegetation of control plots located in a similar but undisturbed habitat was compared with that of 18 burrow plots established at badger setts (N = 9) and fox dens (N = 9) in a lowland forest area in Poland. Soil physicochemical properties at different disturbance levels (mounds, intermounds and reference areas) were also investigated. The animals altered nutrient availability in the burrow plots considerably by excavating material from deep soil horizons that were less acidic and higher in K, Ca, Mg and available P but poorer in C and N. The effect was stronger for the badger, probably because it displaced larger amounts of material and disturbed wider areas. The activity of the two carnivores induced similar changes in plant communities. They increased herbaceous species richness and caused a shift in the herbaceous species composition: versus the control plots, the burrow plots contained more fugitive species (short-living plants typical for disturbed environments), among which ruderal forbs, including nutrient-demanding species, dominated. The carnivores also increased the species richness of fleshyfruited shrubs and trees. The primary reason for this was probably not burrowing but endozoochorous seed dispersal. Overall, the results indicate that the badger setts and fox dens differ significantly from the forest matrix in terms of soil and vegetation parameters, and that they contribute to habitat heterogeneity and biological diversity.
