Habitat heterogeneity as a driver of ungulate diversity and distribution patterns: interaction of body mass and digestive strategy (2009, background): “Ecological theory has linked heterogeneity to savanna herbivore diversity pattern through the role of spatial resource partitioning as a condition for species coexistence (Ritchie & Olff, 1999; Wilmshurst et al ., 2000; Arsenault & Owen-Smith, 2002; Cromsigt & Olff, 2006).”
Resource partitioning along multiple niche dimensions in differently sized African savanna grazers (2011, background): “2009) and breadth of incisor arcade (Illius and Gordon 1987, Arsenault and Owen-Smith 2008) may be better predictors for explaining resource partitioning. Our findings provide strong support for the role of body size in resource partitioning between grazing herbivores weighing less than 1000 kg. Dur”
Integrating ecological roles and trophic diversification on coral reefs: multiple lines of evidence identify parrotfishes as microphages (2016, background): “…partitioning in Serengeti ungulates is a strong driver of succession in plant communities (Murray & Brown, 1993), and can lead to feeding facilitation where grazing by some species stimulates regrowth of vegetation that improves forage quality for other species (Arsenault & Owen-Smith, 2002).”
Grazing lawns contribute to the subsistence of mesoherbivores on dystrophic savannas (2006, result): “Our study thus provides field evidence to support the suggestion by Arsenault and Owen-Smith (2002) that as the dry season progresses, the facilitative effect of grazing fades away.”
Density dependent and temporal variability in habitat selection by a large herbivore; an experimental approach (2009, background): “The steady increase in use of the high productivity habitat (meadows) over the four years, as found in our study, is at least indicative of grazing facilitation (Arsenault and Owen-Smith 2002); i.”
Resource partitioning by grass height among grazing ungulates does not follow body size relation (2008, background): “…Serengeti, it has been widely accepted that resource partitioning among large mammalian grazers occurs partly through differential selection for grass canopy height by herbivores differing in body size (Owen-Smith 1985, Illius and Gordon 1987, Murray and Illius 1996, Arsenault and Owen-Smith 2002).”
Dry season diets of sympatric ungulates in lowland Nepal: competition and facilitation in alluvial tall grasslands (2006, background): “Generally, food is most limiting for herbivores in the dry season, when it is of poor quality (Arsenault and Owen-Smith 2002).”
Behavioural interference between ungulate species: roe are not on velvet with fallow deer (2011, background): “Overlap amplifies the potential for interspecific competition, which may depend on a variety of factors, e.g. availability of a scarce resource or the introduction of alien taxa (Hobbs et al. 1996; Arsenault and Owen-Smith 2002; Gurnell et al. 2004; Ahola et al. 2007).”
Can Invasive Species Facilitate Native Species? Evidence of How, When, and Why These Impacts Occur (2006, background): “competition, predation, physical stress) in establishing and maintaining community dynamics (Callaway and Walker 1997; Bertness et al. 1999; Goldberg et al. 1999; Arsenault and Owen-Smith 2002), and needs to be incorporated into future ecological testing and theory (Kareiva and Bertness 1997; Stacho”
Ecological Engineering by a Mega-Grazer: White Rhino Impacts on a South African Savanna (2008, background): “Both Rhino and Hippo prefer to feed in areas of short grass (Lock 1972; Olivier and Laurie 1974; Owen-Smith 1975), a habit to which they are suited by their wide mouths and low slung head, and help create and maintain short grass patches (Eltringham 1970; Arsenault and Owen-Smith 2002; Verweij and”
