Effects of reindeer browsing on tundra willow and its associated insect herbivores (2004, background): “Intense grazing and browsing may lead to changes in vegetation patterns (Leader-Williams, Smith & Rothery 1987; Oksanen, Moen & Helle 1995; Suominen & Olofsson 2000; Augustine & McNaughton 2004) and, in the worst case, a loss of productivity of the most preferred food plants.”
Synthesizing the effects of large, wild herbivore exclusion on ecosystem function (2019, background): “In African savannas, fire and large herbivores together suppress woody vegetation growth and facilitate grasses (Augustine & McNaughton, 2004; Staver, Bond, Stock, Rensburg, & Waldram, 2009).”
The ivory trade and elephant conservation (2004, background): “Elephants reducing woodlands to mixed grasslands can actually increase biodiversity (Gillson & Lindsay 2003), and they can provide an important service by suppressing shrub encroachment on commercial rangelands (Augustine & McNaughton 2004).”
Goat grazing, its interactions with other herbivores and biodiversity conservation issues (2012, background): “Goats control shrub encroachment (particularly of Acacia species) less efficiently than dik-dik (Augustine and McNaughton, 2004) and eat more grasses than kudu and gazelle, but less than impala (Owen-Smith and Cooper, 1985; Hoppe et al., 1977).”
Savanna woody plant dynamics: the role of fire and herbivory, separately and synergistically (2010, background): “This is seen in the herbivorerich community ofAfrican savannas,where small-sized browsers have been found to be able to limit tree dynamics (Augustine and McNaughton 2004). In particular, impala may dramatically impair tree recruitment (e.g. along the Chobe riverfront, Botswana; Moe et al. 2009), wi”
Native ungulates of diverse body sizes collectively regulate long‐term woody plant demography and structure of a semi‐arid savanna (2013, methodology): “Previous short-term research at this site found that levels of defoliation are greatest for saplings <0.5 m tall due to intensive, year-round browsing by small ungulates, particularly dik-dik (Madoqua sp.; Augustine & McNaughton 2004).”
Plant Herbivore Interactions at the Forest Edge (2008, background): “etbaica (Augustine and McNaughton 2004); and deer browsing in temperate forests suppresses tree regeneration of Abies alba and Acer pseudoplatanus (Ammer 1996).”
Contrasting effects of cattle and wildlife on the vegetation development of a savanna landscape mosaic (2010, background): “…of landscape heterogeneity through their effects on plant communities (McNaughton 1984; Adler, Raff & Lauenroth 2001; Tobler, Cochard & Edwards 2003; Augustine & McNaughton 2004; Waldram, Bond & Stock 2008), Rarely, however, are the effects of cattle and large ungulate wildlife studied together.”
Local versus landscape‐scale effects of savanna trees on grasses (2009, background): “In parts of sub-Saharan Africa, however, tree densities are declining due to heavy browsing (primarily by elephants) inside parks and protected areas (Birkett 2002; Augustine & McNaughton 2004; Western & Maitumo 2004) and harvesting of trees for charcoal production outside of protected areas.”
What Limits Trees in C4 Grasslands and Savannas (2008, background): “Using exclosures, Augustine & McNaughton (2004) showed that browsing by a small African antelope reduced the rate of shrub increase in an African rangeland from 137 to 7 shrubs ha−1 year−1.”
A patch-dynamics approach to savanna dynamics and woody plant encroachment – Insights from an arid savanna (2006, background): “Grazing has two indirect effects on the tree recruitment bottleneck by reducing grass biomass and thereby (i) reducing competition from grasses, and (ii) altering the fire regime, while browsing may retard transition to mature size classes (Bergström, 1992; Augustine and McNaughton, 2004).”
Consequences of herbivory by native ungulates for the reproduction of a savanna tree (2007, background): “Dublin et al . 1990; van Langevelde et al . 2003; Augustine & McNaughton 2004 ).”
Is there a ‘browse trap’? Dynamics of herbivore impacts on trees and grasses in an African savanna (2014, background): “…structure, despite extensive localized evidence that the impacts of herbivores can be substantial (Prins & van der Jeugd 1993; Barnes 2001; Augustine & McNaughton 2004; Côt e et al. 2004; Sharam, Sinclair & Turkington 2006; Fornara & Du Toit 2007; Asner et al. 2009; Holdo et al. 2009;…”
