Grazing lawns contribute to the subsistence of mesoherbivores on dystrophic savannas (2006, unknown): “(Owen-Smith 1988, Eltringham 1999, Augustine et al. 2003 ).”
An integrated perspective to explain nitrogen mineralization in grazed ecosystems (2013, background): “…hese theories advocate that herbivores can speed up soil N cycling hrough the deposition of dung and urine, which provide easly available nutrients and stimulate the activity of soil microbes Frank and McNaughton, 1993; McNaughton et al., 1997b; Frank nd Groffman, 1998; Augustine et al., 2003).”
Herbivore and neighbour effects on tundra plants depend on species identity, nutrient availability and local environmental conditions (2007, background): “Empirical studies from more productive savanna ecosystems show how grazing ungulates selectively consume plant biomass in more nutrient-rich and productive sites (McNaughton et al. 1989; Milchunas & Lauenroth 1993; Augustine et al. 2003).”
LARGE HERBIVORES SUPPRESS DECOMPOSER ABUNDANCE IN A SEMIARID GRAZING ECOSYSTEM (2004, background): “%) at nutrient-poor sites (Augustine et al. 2003).”
Do herbivores exert top-down effects in Neotropical savannas? Estimates of biomass consumption by leaf-cutter ants (2008, background): “…have demonstrated that plant communities in Paleotropical savannas are regulated by a combination of pervasive bottom-up effects, such as precipitation and soil nutrient levels, and top-down effects such as fire and mammalian herbivory (e.g. Cumming 1982; Roques et al. 2001; Augustine et al. 2003).”
Savanna glade hotspots: Plant community development and synergy with large herbivores (2012, background): “…herbivores may forage in nutrient-rich corral areas and excrete elsewhere (thereby exporting nutrients) or may excrete in nutrient-rich areas, thereby compensating, or overcompensating, for the nutrients that are removed via herbivory (McNaughton, 1984; Adler et al., 2001; Augustine et al., 2003).”
Savanna herbivore dynamics in a livestock-dominated landscape. II: Ecological, conservation, and management implications of predator restoration (2007, background): “Even if nutrient deficiencies also limit wild herbivore performance (Sinclair, 1974; McNaughton and Georgiadis, 1986; Augustine et al., 2003 ), they are unlikely to trigger protracted and selective herbivore declines in the absence of other factors.”
The Stoichiometry of Nutrient Release by Terrestrial Herbivores and Its Ecosystem Consequences (2017, background): “At the same time, large parts of the landscape with poorer quality vegetation experience a net removal of nutrients (McNaughton et al., 1997; Augustine et al., 2003; van der Waal et al., 2011).”
