Unintentional toxicosis from methylxanthines in chocolate‐based baits consumed by American black bears

open access: yesWildlife Society Bulletin, 2016
The use of baits often increases success for many wildlife management activities, including wildlife capture for research, harvest by hunters and trappers during regulated activities, and lethal and nonlethal control for damage management.

Predicted genetic consequences of alternative population control strategies for North American plains bison in Yellowstone National Park

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Management of bison in Yellowstone National Park under the available strategies that maintained ≥3,500 individuals (1:1 sex ratio), removed <40% of the population at a time and prioritized relatives for removal were predicted to maintain genetic variation at levels consistent with long‐term conservation (>95% of existing variation).

Evaluation of dexmedetomidine, tiletamine, and zolazepam for the immobilization of black bears

open access: yesWildlife Society Bulletin, 2015
Telazol® (TZ, tiletamine hydrochloride [HCl] and zolazepam HCl) has been used to immobilize black bears for research and management activities since the 1980s. Although considered an effective and safe drug, TZ has some disadvantages, including prolonged

Individual Identification of Prey in Carnivore Scats

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Noninvasive genetic sampling is widely used in ecology and conservation to identify predators and their diets but recovering individual‐level information from consumed prey remains largely unexplored. We evaluated whether individual prey can be reliably genotyped from carnivore scats and assessed limitations associated with degraded and mixed ...

Portable Electric Fencing for Bear Deterrence and Conservation

open access: yesHuman-Wildlife Interactions, 2018
Although bear-inflicted (Ursus spp.) human fatalities are rare in North America, human injuries, property damage, and bear mortalities occur wherever bears and humans commingle.

Quantifying Southern Sea Otter (Enhydra lutris nereis) Reactions to a Quadcopter Drone in Central California

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Drones are useful for wildlife research and management, but they can cause disturbance and harassment to wildlife. Sea otters (Enhydra lutris) are candidates for drone‐based observation and monitoring but are vulnerable to disturbance. No studies have evaluated drone effects on sea otter behavior, but based on prior disturbance studies, we ...

Characterizing Nontarget Species Use at Bait Sites for White-Tailed Deer

open access: yesHuman-Wildlife Interactions, 2017
Baiting white-tailed deer (Odocoileus virginianus) has evolved into a controversial issue of wildlife management. During August–September 2012, we established a grid of 64 cameras in the Upper Peninsula of Michigan at sites baited with corn that ...

Distance-Dependent Effectiveness of Diversionary Bear Bait Sites

open access: yesHuman-Wildlife Interactions, 2017
Baiting black bears (Ursus americanus) to sites outside a community can alleviate famine-induced spikes in human–bear conflicts. But little is known about effects of distance between baits and communities.

Potential distribution of Ursus americanus in Mexico and its persistence: Implications for conservation

open access: yes, 2016
The black bear Ursus americanus is an endangered species in Mexico. Its historical distribution has decreased by approximately 80% although its current distribution is not known with precision; it is only reported to be present in the mountains of ...
