Can Reindeer Overabundance Cause a Trophic Cascade? (2007, background): “In the present study we recorded the presence–absence of fecal pellets of hares (Hulbert and others 1996), ptarmigan (compare Schaefer and others 1996) and reindeer (Edenius and others 2003; Van der Wal and Brooker 2004) in the triangular plots along the sampling lines (Figure 2).”
Impact of climate change on zooplankton communities, seabird populations and arctic terrestrial ecosystem—A scenario (2007, unknown): “…and Garkavaya, 1975; Galkina, 1977; Krzyszowska, 1992; Bakker and Loonen, 1998; Wegener and Odasz-Albrigtsen, 1998; Jefferies and Rockwell, 2002; Juchnowicz-Bierbasz and RakusaSuszczewski, 2002; Stark et al., 2002; RakusaSuszczewski, 2003; Olofsson et al., 2004; Van der Wal and Brooker, 2004).”
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).”
Herbivory influences tree lines (2004, background): “For example, although trampling by large ungulates may have a negative impact on seedlings in some situations, trampling may also reduce existing vegetation cover and thereby increase soil temperatures and facilitate vascular plant growth (e.g. van der Wal & Brooker 2004).”
Ecosystem feedbacks and cascade processes: understanding their role in the responses of Arctic and alpine ecosystems to environmental change (2009, background): “…mechanisms that result from this, have been proposed as a major driver of shifts between moss and grass dominated tundra (Zimov et al. 1995; van der Wal and Brooker 2004), an idea that is currently being tested in the 'Pleistocene Park' 6 (Zimov 2005); and even shrub encroachment can be affected…”
The effects of reindeer grazing on the composition and species richness of vegetation in forest–tundra ecotone (2008, background): “There is evidence that reindeer grazing may increase the abundance of graminoids (Olofsson et al. 2001; van der Wal and Brooker 2004; Olofsson 2006a) and thus increase the productivity of vegetation (van der Wal 2006).”
