The Normalized Difference Vegetation Index (NDVI): unforeseen successes in animal ecology (2011, background): “Thus, mature grasslands may provide high vegetation productivity (i.e. high NDVI values), yet few resources to ungulates (Wilmshurst et al. 2000, Bergman et al. 2001, Payero et al. 2004, Hebblewhite et al. 2008).”
Facing herbivory as you grow up: the ontogeny of resistance in plants. (2005, background): “Foraging on large plants, providing a considerable amount of food, is likely to be more rewarding than moving in the landscape to find ‘small bites’ in younger plants [ 47 ].”
Bite rates in Rocky Mountain bighorn sheep (Ovis canadensis): effects of season, age, sex and reproductive status (2003, background): “While feeding, animals must also be vigilant to avoid predation, leading to a trade-off between foraging and alertness (Bergman et al. 2001; Hudson and White 1985; McNamara 1990).”
How a mega‐grazer copes with the dry season: food and nutrient intake rates by white rhinoceros in the wild (2006, background): “In contrast, Bison ( Bison bison ) maximized immediate rates of food intake rather than long-term energy gains ( Bergman et al . 2001; Fortin, Fryxell & Pilote 2002).”
In search of forage: predicting dynamic habitats of Mongolian gazelles using satellite-based estimates of vegetation productivity (2008, background): “Mature forage may provide high vegetation productivity, yet few resources to gazelles as digestion rates are reduced (Fryxell 1991; Murray & Illius 1996; Wilmshurst et al . 1999; Wilmshurst, Fryxell & Bergman 2000; Bergman et al . 2001 ).”
Evolutionary Foraging Models in Zooarchaeological Analysis: Recent Applications and Future Challenges (2007, background): “However, it might surprise anthropologists and archaeologists to know that the choice of currency and identification of goal are not presumed to be static or invariant in current studies of nonhuman foragers (e.g., Bergman et al. 2001; Kacelnik and Krebs 1997; Welham and Beauchamp 1997).”
The ecology of forest elephant distribution and its implications for conservation (2002, background): “Whether the currency of foraging success is ‘energy maximisation’ (Fryxell 1991) or ‘time minimisation’ (Bergman et al. 2001) the central point is that foraging efficiency should be maximised within the constraints of environment or physiology.”
An improved method for quantifying intake rate and ingestive behaviour of ruminants in diverse and variable habitats using direct observation (2004, background): “from a few hours to a whole day, according to different authors (Bergman et al., 2001).”
Searching behavior and use of sampling information by free-ranging bison (Bos bison) (2003, methodology): “Because digestibility was established using cattle rumen fluid, these equations were converted to reflect bison digestibility following Bergman et al. (2001) .”
Digestively constrained predators evade the cost of interference competition (2004, background): “Although some recent studies showed maximization of short-term intake rate, explained by fitness-costs associated with foraging (Illius et al . 1999; Bergman et al . 2001; Fortin et al . 2002), maximization of long-term intake rate seems to be the general ‘rule’ (reviewed by Stephens & Krebs 1986;”
