      Terekhina, Alexandra; Volkovitskiy, Alexander; Sokolova, Natalya A.; Ehrich, Dorothee; Fufachev, Ivan A.; Sokolov, Aleksandr A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-12)
      Human-wildlife problems often arise when predators kill livestock. This can develop into serious conflicts between traditional pastoralists and other stakeholders, such as government officials and conservationists. In the Yamal Peninsula (Russia), nearly half of the indigenous Nenets people are reindeer herders. They have recently faced many challenges, such as high mortality of reindeer from pasture ...
    • Dental evidence for variation in diet over time and space in the Arctic fox, Vulpes lagopus 

      Ungar, Peter S.; Van Valkenburgh, Blaire; Peterson, Alexandria S.; Sokolov, Aleksandr A.; Sokolova, Natalya A.; Ehrich, Dorothee; Fufachev, Ivan A.; Gilg, Olivier; Terekhina, Alexandra; Volkovitskiy, Alexander; Shtro, Victor (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-16)
      Studies of the effects of variation in resource availability are important for understanding the ecology of high-latitude mammals. This paper examines the potential of dental evidence (tooth wear and breakage) as a proxy for diet and food choice in Vulpes lagopus, the Arctic fox. It presents a preliminary study of dental microwear, gross wear score, and tooth breakage in a sample (n = 78 individuals) ...

      Global warming has pronounced effects on tundra vegetation, and rising mean temperatures increase plant growth potential across the Arctic biome. Herbivores may counteract the warming impacts by reducing plant growth, but the strength of this effect may depend on prevailing regional climatic conditions. To study how ungulates interact with temperature to influence growth of tundra shrubs across ...
