“…100,000 in 1960 (Makeev et al., 2014) to officially over 225,000 animals today (FAO, 2022). Several studies show that reindeer herding is the most important driver of vegetation change in Yamal leading to damage or even complete destruction of the lichen cover, inhibition of shrub expansion and promotion of secondary graminoid dominated vegetation communities (Forbes et al., 2009; Kryazhimskiy et al., 2011; Spiegel et al., 2023).…”

“…These vegetation changes are likely to increase the habitat available to more southern small rodent species, notably folivorous voles. Moreover, human activities such as intensive reindeer herding as well as infrastructure development and off‐road driving, transform the landscape and can cause vegetation shifts towards non‐typical tundra communities dominated by graminoids (Kryazhimskiy et al., 2011; Sokovnina & Ektova, 2020; Tuomi et al., 2021). The spread of such habitats could favor the expansion of species living in meadows such as narrow‐headed voles ( Lasiopodomys gregalis ; Sokolova, 2004).…”

Range shifts and changes in dominance of species in communities are among the major predicted impacts of climate change on ecosystems, supported by numerous modeling studies. While climate is changing particularly rapidly in the Arctic, little observational data is available to document predicted changes in the composition of communities, in particular from the large Russian tundra areas. Small rodents are a key component of tundra ecosystems implementing important ecological functions both as herbivores and as main prey for a whole guild of predators. Here we document changes over 60 years in occurrence of nine species of small rodents along a latitudinal gradient spanning from the forest‐tundra ecotone to the high Arctic tundra on Yamal Peninsula. All data were obtained using a single method: snap‐trapping. In general, the occurrence of lemmings, specialized arctic endemics, decreased in the southern parts of the peninsula, whereas the occurrence of voles, representing boreal or wide‐spread species, increased and expanded northwards. The occurrence of Siberian lemmings (Lemmus sibiricus) in particular declined over the whole latitudinal gradient and possibly disappeared from the southernmost zones, whereas collared lemmings (Dicrostonyx torquatus) declined significantly only in the forest tundra. The strongest increase was observed in the tundra zones for narrow‐headed voles (Lasiopodomys gregalis), a wide‐spread species inhabiting meadows and riparian habitats, and Middendorff's voles (Alexandromys middendorffii), a primarily low Arctic species inhabiting waterlogged tundra. Both species also expanded their distribution range northwards during the last two decades. The observed changes might be due to the effect of several drivers of environmental change occurring in concert: climate warming both in winter and in summer, and increased human activity notably related to intensive reindeer herding and industrial development.

“…Throughout the year, deer are on pasture maintenance and need plant resources. A significant growth of livestock number, as well as the disturbance of vegetation under human influence, led to a reduction in the area of pastures, and in some areas to desertification of territories (Kryazhimsky, 2011). Considering a shortage of pasture area, the assessment of food quality becomes especially relevant, one of the criteria of which is its safe chemical composition.…”

Total mercury content in soils and lake sediments of Vilkitsky Island (Kara Sea)

Licensed under a Creative Commons Attribution 4.0 International License Mercury threatens Arctic ecosystems due to its well known deleterious effects. The development of energy resources in the Russian Arctic is currently being planned, which will inevitably be accompanied by emissions of heavy metals into the environment, but little is known about the distribution of mercury in soils of the permafrost regions. Total mercury (THg) concentrations were investigated in soils and lake sediments of Vilkitsky Island located in remote area of the Arctic. The concentration of mercury in soils varied from 1 to 36,6 ng/g, in lake sediments -from 2.0 to 5.8 ng/g. In sandy soils of the iseland the concentration of THg was minimal and was usually not higher than10 ng/g, whereas in loamy soils it was 3.5 times higher. Correlation analysis has shown that THg concentration depended primarily on particle size distribution, in a lesser degree -on total carbon and total nitrogen concentrations. The soils of Viltisky Island have one of the lowest mercury concentration in comparison to soils of other Arctic territories, because of the predominance of sandy marine sediments and low soil organic matter content. Under influence of human activities, THg content has increased three-fold on average. The highest concentrations were observed in soils of an abandoned polar station. Calculation of CF and Igeo coefficients demonstrated the high level of mercury pollution on local sites. The maximum content of mercury (25.7-36.7 ng/g) was observed in coastal sediments. It is assumed that the increased mercury content is a consequence of translocation. Thus, the coastal areas of the Arctic islands are at the greatest danger of pollution.

“…In other pastoralist systems, similar debates have taken place during the past decades. In reindeer pastoralist systems in Sweden, Finland and Russia pasture degradation due to overgrazing is still being debated, and there is an emerging understanding that these areas are in fact cultural landscapes created by the practice of pastoralism (Torp 1999;Forbes et al 2006;Kryazhimskii et al 2011). In other environments (e.g.…”

A tragedy of errors? Institutional dynamics and land tenure in Finnmark, Norway

Abstract:Reindeer herding in Finnmark has been widely perceived during the last few decades as a perfect example of the tragedy of the commons. The present article claims that this discourse relies on flawed assumption regarding land tenure. Our historical analysis of the term 'common' in relation to resources in Finnmark shows the term to reflect a misunderstanding of local categories, practices, and concerns related to pastures, territories, and natural resources more generally. In this sense, it exposes a case of 'mistaken identity' between the formal legal conception of 'commons' and the customary rules and thinking of reindeer herders. We turn to different strands of critical institutionalism to analyse the processes of institutional change that have allowed these errors and misunderstandings to be formalised and naturalised in the current governance system. We show that a process of institutional bargaining between the Norwegian Parliament, the Sámi Parliament, and the International Labour Organisation has recently re-enforced an alien conception of a 'commons' to which ambiguous groups of people have equivocal rights. In parallel, a process of institutional layering of new regulatory actors and rules on top of existing ones has taken place. This regulatory ratcheting has resulted in the blurring of the authorities and jurisdictions intrinsic in the customary tenure system. Moreover, the new layers of regulations have actively overemphasized the Sámi customary obligation of sharing resources to legitimize 1 The "Results" section of the present article is developed from our book chapter "Er Finnmarksvidda en allmenning?" forthcoming in Norwegian in Benjaminsen et al. (2015). 20Andrei Marin and Ivar Bjørklund the new, ambiguous, conception of commons. This process is explained as one of institutional bricolage based on naturalisation by analogy and authority processes that allow certain powerful actors to influence the production of institutional arrangements favourable to them. All three processes underline the negotiated, dynamic nature of institutional change. We propose this integrative analysis of institutional and general social dynamics is beneficial in studying commons as everyday practices affecting natural resource governance.
