Recolonizing Mountain Lions (Puma concolor) in A Region Dominated by Private Land Ownership in The Great Plains: Management Challenges, Considerations and Perspectives
Jon P. BECKMANN and Matt PEEK
CWBM 13 (2): 5 – 11
Management of mountain lions (Puma concolor) can oftentimes be contentious. This is particularly true in regions that contain a large proportion of privately owned land and high levels of livestock production, where threats can be both real and perceived.
Read MoreModel Limitations and Data Gaps Complicate Predictions of Mountain Lion Recolonization in Missouri
Nathaniel R. BOWERSOCK, Kara B. GREGORY, and Mariela G. GANTCHOFF
CWBM 13 (2): 12 – 16
Mountain lions (Puma concolor) were once distributed throughout much of the western hemisphere, but within North America have been reduced to a smaller range due to human activities. However, mountain lion populations have grown and have been expanding eastward over the last several decades.

Broad Patterns of News Sentiment about Mountain Lions (Puma concolor) in The US from 2000–2015
L. Mark ELBROCH, Tyler ALBRETHSEN, Kevin McMANIGAL, Christina DEMETRIO, W. Connor O’MALLEY, Andrew STRATTON, Read BARBEE, Hugh ROBINSON
CWBM 13 (2): 17 – 26
Negative sentiment and misinformation in media can undermine conservation strategies and exacerbate human-carnivore conflict. Here we explored media trends regarding a charismatic carnivore, the mountain lion (Puma concolor), from 2000–2015 and tested whether the number of physical attacks on people in a calendar year predicted annual news sentiment about mountain lions.

Mountain Lion Predation on Mule and Black-tailed Deer: A Perspective on The Complex Impacts of An Iconic Predator
Tavis D. FORRESTER and Heiko U. WITTMER
CWBM 13 (2): 27-40
Predation is a fundamental process that shapes ecological communities. The impact of mountain lion (Puma concolor) predation on their prey, however, is a debated topic among wildlife managers and their primary constituents, hunters and conservationists in North America.

Survival and Mortality Factors for Mountain Lions in The Davis Mountains of West Texas: Implications for Managing A Sustainable Population
Patricia Moody HARVESON, Amanda Veals DUTT, Catherine C. DENNISON, Bert W. GEARY, Dana MILANI, Ron THOMPSON, and Louis A. HARVESON
CWBM 13 (2): 41-49
Mountain lion (Puma concolor) population dynamics are greatly influenced by harvest as an additive source of mortality across their range. Texas presents a unique situation where mountain lions are classified as a non-game animal with no restrictions on harvest.

Jaime L. RUDD, Robert H. POPPENGA, Leslie W. WOODS, Seth P. D. RILEY, Jeff A. SIKICH, Nicolás STREITENBERGER, and Deana L. CLIFFORD
CWBM 13 (2): 50 – 63
Anticoagulant rodenticides (ARs) are used worldwide to control rodent pests. There are 2 general groups of ARs: first-generation anticoagulant rodenticides (FGARs) and second-generation anticoagulant rodenticides (SGARs). Both pose a significant risk of toxicosis to non-target wildlife.

Veronica YOVOVICH1, Laurel E. K. SERIEYS, Trent PEARCE, Caitlin KUPAR, Andrew STRATTON, Rana BAYRAKCISMITH, Kim SAGER-FRADKIN, Dylan BERGMAN, Bethany ACKERMAN, Kristen PHILLIPS, Greg JONES, and L. Mark ELBROCH
CWBM 13 (2): 64 – 74
Anticoagulant rodenticides are used globally to control rodent populations and are a growing concern for their potentially lethal spillover effects on nontarget wildlife species, particularly predatory species. We conducted a surveillance study to examine the levels at which wild felids are exposed to anticoagulant rodenticides on the Olympic Peninsula in Washington, USA.

Gilbert PROULX, Sadie PARR, and L. Mark ELBROCH
CWBM 13 (2): 75 – 81
In this study, we reviewed 2011–2020 captures of mountain lions (Puma concolor) on 27 traplines in the 13,660 km2 fur zone that is adjacent to Banff and Jasper National Parks, Alberta. A total of 17 mountain lion non-target captures in canid killing neck snares were reported during 2011–2020 in the fur zone.
Read MoreImpact of Sublethal Injuries on Mountain Lion Predation and Spatial Ecology
Jacob A. HARVEY, Quinton MARTINS, and John F. BENSON
CWBM 13 (2): 82 – 101
Carnivores are at risk of injury or death from natural activities (e.g., predation, terrain) as well as from human encounters. While humans kill carnivores in response to real or perceived threats to human life, livelihoods, or property, not all encounters are fatal, and sublethal injuries can occur.

A Collaborative Approach to Initiating Mountain Lion (Puma concolor) Policies in Texas
L. Mark ELBROCH, Ben MASTERS, Monica MORRISON, Romey SWANSON, Pam HARTE, Jay TISCHENDORF, Patricia M. HARVESON
CWBM 13 (2): 102 – 110
Enforceable legislation, policy, and regulation are powerful conservation tools because of their large geographic extent and the longevity of their impact on wildlife populations. For these reasons, passing legislation, policy, and regulation have been a focused activity for parties interested in managing wildlife, whether that be to increase utilization/consumption or protection/conservation.
Read MoreA Call for Research on Reducing Livestock-Mountain Lion Conflict
Omar OHRENS, Nicolás LAGOS, Veronica YOVOVICH, and L. Mark ELBROCH
CWBM 13 (2): 111 – 119
Carnivore predation of livestock poses significant challenges for pastoral communities, and the often-resulting lethal removal of carnivores threatens their conservation, particularly with species like mountain lions (Puma concolor).

Nicolás LAGOS, Javiera de la FUENTE, Marcos ARCE, and Carlos ROMÁN
CWBM 13 (2): 120 – 125
Large carnivores play a crucial role in ecosystem stability, yet interactions with human activities, particularly livestock grazing, have disrupted this balance, leading to conflicts between conservation and economic interests. Livestock ranching, vital for many communities, often overlaps with carnivore habitats, resulting in preemptive or retaliatory killings.

Evaluating The Efficacy of Aversive Conditioning of Mountain Lions with Hounds
Mitchell A. PARSONS, Bart E. GEORGE, Julie K. YOUNG
CWBM 13 (2): 126 – 137
Human-wildlife conflict creates negative outcomes for both people and wildlife by threatening human safety and property and leading to the persecution of wildlife. Conflict with large carnivores results in real and perceived threats to human interests and safety, and thus a range of management tools is necessary to mitigate conflict and facilitate coexistence between humans and carnivores.
