The taxonomic diversity of quarry vegetation in northwest Siberia and Chukotka

Land use and land cover change in Arctic Russia: Ecological and social implications of industrial development

“…Earlier studies have reported similar results, according to which a decrease in species richness has been related to different forms of industrialization, off-road traffic, roads, railroads, quarries, and chemical disturbance (Sumina, 1998;Forbes et al, 2001;Khitun and Rebristaya, 2002;Lavrinenko et al, 2003). By incorporating the herders' perspective, our study supports the holistic landscape approach, where lowering of biological diversity is seen as linked to reduced indigenous access and so-called ecodiversity (Naveh, 1995).…”

“…The regrowth of vegetation was generally greater in mires than in other vegetation types supporting earlier studies that have shown that the more moisture there is in the soil, the faster the vegetation regenerates (Rebristaya et al, 1993;Andreyashkina and Peshkova, 1997;Forbes et al, 2001). The spreading of graminoid-dominated vegetation at the expense of other plant groups -sometimes referred to as 'grassification' (Shchelkunova, 1993) -and the persistence of the effects have been well known for some time from studies of industrial disturbance in Russian and North American tundra regions (Forbes, 1992;Khitun, 1997;Sumina, 1998;Forbes et al, 2001;Khitun and Rebristaya, 2002;Lavrinenko et al, 2003). Like most other plant groups, except for graminoids, bryophytes had regenerated poorly after the disturbance.…”

Comparative Ordination of Low Arctic Vegetation Recovering from Disturbance: Reconciling Two Contrasting Approaches for Field Data Collection

“…The oldest quarries surveyed (> 10 yr) are located near the base of the corridor, in Obskaya/ Labytnangi. The quarries near Laborovaya had been abandoned for 6 yr at the time of sampling and their origins and environment are previously described (Forbes, 1995(Forbes, , 1997Sumina 1996Sumina , 1998. At the same site, the berms from the railway bed (stone ballast) and the roadside (unsorted cobbles and sand) had also been established 6 yr prior to sampling.…”
