Large scale experimental effects of three levels of sheep densities on an alpine ecosystem (2008, background): “Finally, bryophytes which hardly are foraged by large herbivores in alpine environments, are disturbed by trampling which may cause short-term negative responses, while indirect competitive effects from graminoids are expected to have a negative effect on a long term scale (Virtanen 2000).”
Can Reindeer Overabundance Cause a Trophic Cascade? (2007, background): “…in northern Fennoscandia (Stenseth and Ims 1993), most lemming peaks during the last century have been small (Angerbjörn and others 2001) and there seem to be periods of 20–30 years between peak years with substantial impacts on the vegetation (Henttonen and Kaikusalo 1993; Virtanen 2000).”
Arctic lemmings, Lemmus spp. and Dicrostonyx spp.: integrating ecological and evolutionary perspectives (2008, background): “In Fennoscandia, the strong impacts of lemmings are found in winter habitats – on moist but not waterlogged sites with deep snow (Nordhagen, 1928; Kalela, 1971; Oksanen and Oksanen, 1981; Moen et al., 1993; Virtanen, 2000; Virtanen et al., 2002).”
Importance of large and small mammalian herbivores for the plant community structure in the forest tundra ecotone (2004, result): “This finding is consistent with previously reported impacts of microtines in non-peak years (Oksanen and Moen 1994, Virtanen et al. 1997, Virtanen 2000, Grellmann 2002).”
Vertebrate herbivores and ecosystem control: cascading effects of faeces on tundra ecosystems (2004, background): “(Virtanen 2000, Olofsson et al. 2001), and that indirect herbivore impacts, in particular, may be prevalent in the cold and strongly resource-limited arctic environment (Jefferies 1988, Hik et al. 1991, Jefferies et al. 1994, Van der Wal and Brooker 2004).”
Inclusion of biotic stress (consumer pressure) alters predictions from the stress gradient hypothesis (2009, background): “Several studies from both terrestrial and aquatic systems found supporting evidence for this (Virtanen 2000; Graff, Aguiar & Chaneton 2007; van der Wal & Hessen 2009).”
