LARGE HERBIVORES SUPPRESS DECOMPOSER ABUNDANCE IN A SEMIARID GRAZING ECOSYSTEM (2004, background): “Grazers reduce mi- crobial biomass in some cases (Garcia and Rice 1994, Holt 1997, Stark and Grellmann 2002), increase it in some (Singh et al. 1991, Bardgett et al. 1997, 2001, Stark et al. 2002), and have no, or idiosyncratic, effects on it in others (Kieft 1994, Tracy and Frank 1998, Wardle et…”
Large scale experimental effects of three levels of sheep densities on an alpine ecosystem (2008, background): “No effect of sheep grazing on rodent grazing signs (mainly as an effect of winter grazing; Grellmann 2002) was found (P6; Table 1), despite that capture studies recorded higher field vole population growth rates during summer at low grazing as compared to high grazing (Steen et al. 2005).”
Herbivore and neighbour effects on tundra plants depend on species identity, nutrient availability and local environmental conditions (2007, result): “Similar results were recently reported from the Alaskan arctic tundra by Gough et al. (2007), who found that herbivores had a greater impact on the performance of graminoids and a deciduous shrub under amended nutrient conditions (see also Bonser & Reader 1995; Grellmann 2002).”
Reindeer influence on ecosystem processes in the tundra (2004, background): “Although summer grazing by reindeer has been found to enhance nutrient cycling and plant productivity, opposite outcome of grazing has been observed in an arctic tundra heath where herbivory mainly occurred during the winter ( Grellmann 2002, Stark and Grellmann 2002).”
Importance of large and small mammalian herbivores for the plant community structure in the forest tundra ecotone (2004, background): “…diversity of plant commu- nities by decreasing the abundance of preferred species (Bazely and Jefferies 1986, Virtanen et al. 1997, Brathen and Oksanen 2001, Olofsson 2001, Grellmann 2002) and by changing competitive interactions between plants (Mulder and Ruess 1998, Virtanen 1998, Olofsson et al.”
