• Large predators limit herbivore densities in northern forest ecosystems (2012, unknown): “Both black (Ursus americanus) and brown (Ursus arctos) bears commonly prey on neonatal cervids, taking a large percentage of the annual offspring less than 1 month old (Zager and Beecham 2006).”
• Brown bear conservation and the ghost of persecution past (2011, background): “There is in fact evidence from predation studies that North American brown bears are more predatory and consume more meat than European brown bears (e.g. Swenson et al., 2001a; Zager and Beecham, 2006).”
• Consequences of brown bear viewing tourism : A review (2017, background): “thropod predators and ungulate herbivores (Zager and Beecham, 2006; Grinath et al., 2015), and reducing carcass availability for the predator and scavenger guilds (Krofel et al.”
• Foraging strategies by omnivores: are black bears actively searching for ungulate neonates or are they simply opportunistic predators? (2011, background): “following birth (Zager and Beecham 2006) and are responsible for most neonate mortalities in some populations of moose Alces alces and forest-dwelling caribou Rangifer tarandus caribou (Ballard 1992, 1994).”
• Implications of a high-energy and low-protein diet on the body composition, fitness, and competitive abilities of black (Ursus americanus) and grizzly (Ursus arctos) bears (2011, result): “Although both species of bears can be effective predators of juvenile and adult ungulates (Zager and Beecham 2006), the data supported the prediction that grizzly bears would consume more large mammals than consumed by black bears.”
