Wildlife management is science based: Myth or reality?
In the January/February issue of The Wildlife Professional, a group of wildlife leaders discussed what they considered "myths" in wildlife management and invited other wildlife professionals to contribute their favorites. Here, five wildlife professionals take up that theme with their discussions of the scientific basis of wildlife management.Decker, Daniel J.; Organ, John F.; Forstchen, Ann; Schiavone, Michael V.; Fuller, Angela K.
Spatiotemporal heterogeneity in prey abundance and vulnerability shapes the foraging tactics of an omnivore
Prey abundance and prey vulnerability vary across space and time, but we know little about how they mediate predator–prey interactions and predator foraging tactics. To evaluate the interplay between prey abundance, prey vulnerability and predator space use, we examined patterns of black bear (Ursus americanus) predation of caribou (Rangifer...Rayl, Nathaniel; Bastille-Rousseau, Guillaume; Organ, John F.; Mumma, Matthew; Mahoney, Shane P.; Soulliere, Colleen; Lewis, Keith; Otto, Robert; Murray, Dennis; Waits, Lisette; Fuller, Todd

Wild-harvested venison yields and sharing by Michigan deer hunters
An increased societal focus on wildlife as food and recent policy deliberations regarding legal markets for wild-harvested meat are encouraging wildlife managers and researchers to examine the amount, use, and distribution of meat yielded through recreational hunting. We used responses to questions on the Michigan Deer Harvest Study to estimate...Goguen, Amber D.; Riley, Shawn J.; Organ, John F.; Rudolph, Brent A.
Wildlife governance in the 21st century—Will sustainable use endure?
In light of the trajectory of wildlife governance in the United States, the future of sustainable use of wildlife is a topic of substantial interest in the wildlife conservation community. We examine sustainable-use principles with respect to “good governance” considerations and public trust administration principles to assess how sustainable use...Decker, Daniel J.; Organ, John F.; Forstchen, Ann; Jacobson, Cynthia A.; Siemer, William F.; Smith, Christian A.; Lederle, Patrick E.; Schiavone, Michael V.
Examining spatial patterns of selection and use for an altered predator guild
Anthropogenic disturbances have altered species’ distributions potentially impacting interspecific interactions. Interference competition is when one species denies a competing species access to a resource. One mechanism of interference competition is aggression, which can result in altered space-use of a subordinate species due to the threat...Organ, John F.; Mumma, Matthew; Holbrook, Joseph D.; Rayl, Nathaniel D.; Zieminski, Christopher J.; Fuller, Todd K.; Mahoney, Shane P.; Waits, Lisette P.
