Recursive movement patterns: review and synthesis across species (2015, background): “It is well established that large herbivores exhibit nonrandom movements, track areas of highest quality foraging, and repeatedly return to these high-quality foraging locations (Sinclair 1977, Fryxell et al. 1988, 2005, Hewitson et al. 2005, Owen-Smith et al. 2010).”
Resource partitioning along multiple niche dimensions in differently sized African savanna grazers (2011, background): “We attribute this difference to a contrast in size of reserve studied and degree and scale of habitat heterogeneity (Owen-Smith 2004, Fryxell et al. 2005, Cromsigt et al. 2009).”
Competition, predation, and migration: Individual choice patterns of Serengeti migrants captured by hierarchical models (2014, background): “Similarly, the movement of Thomson’s gazelle (Eudorcas thomsoni ) in the Serengeti is closely related to periodic greening of the energy-rich short-grass sward (Fryxell et al. 2004, 2005).”
In search of forage: predicting dynamic habitats of Mongolian gazelles using satellite-based estimates of vegetation productivity (2008, background): “…Ecological Society, Journal of Applied Ecology, 45, 649 –658 heterogeneity may be the critical factor explaining farranging and irregular movement behaviour enlarging Mongolian gazelles’ area needs, as has been demonstrated previously for Thompson gazelles (Gazella thomsoni: Fryxell et al. 2005).”
Strategic management of livestock to improve biodiversity conservation in African savannahs: a conceptual basis for wildlife-livestock coexistence (2016, background): “…to environmental gradients and patchy rainfall and fire events can be an important determinant of domestic herbivore carrying capacity and the long-term sustainability of wild herbivore populations (Owen-Smith 2004; Fryxell et al. 2005; Hobbs et al. 2008; Augustine 2010; Fynn & Bonyongo 2011).”
Moose Alces alces habitat use at multiple temporal scales in a human-altered landscape (2011, background): “Herbivoresmayoptimise their foraging by tracking spatiotemporal variation in quality and quantity of food caused by variation in weather and site productivity (Fryxell et al. 2005).”
The portfolio concept in ecology and evolution (2015, background): “…1970 1980 1990 2000 Year stable 1–2 3–4 5–6 7–8 aquatic terrestrial Portfolio effects and biological systems DE Schindler et al. 260 www.frontiersinecology.org © The Ecological Society of America movement prevent animals from tracking variation in vegetation quality (Fryxell et al. 2005).”
On the adaptive benefits of mammal migration (2014, background): “2000), tropical populations of whiteeared kob (Kobus kob leucotis (Lichtenstein and Peters, 1853)), tiang (Damaliscus korrigum korrigum (Ogilby, 1837)), zebra, Thomson’s gazelle, and wildebeest (Fryxell et al. 2005; Holdo et al. 2009), although often there are meaningful gradients in rainfall or pri”
Global decline in aggregated migrations of large terrestrial mammals (2009, unknown): “0 (Hack et al. 2002)* 1000s - South Africa’s Karoo (Skinner 1993) Extinct (Hack et al. 2002)* ~200 (Campbell & Borner 1995*, Fryxell et al. 2004, 2005) ~160 calculated from Sinclair & NortonGriffiths (1979) (Serengeti, Tanzania)* ~150000 (East 1988)*, ~350000 (Campbell & Borner 1995)*, ~250000 -…”
Habitat heterogeneity as a driver of ungulate diversity and distribution patterns: interaction of body mass and digestive strategy (2009, methodology): “Fryxell et al. (2005) argued, using Serengeti as an example, that protected areas have to be sufficiently large so that animals can migrate between key habitats or have to be very heterogeneous (i.e. low spatial autocorrelation in resource availability) to allow populations to persist in smaller…”
