Evaluating fladry designs to improve utility as a nonlethal management tool to reduce livestock depredation

open access: yesWildlife Society Bulletin, 2015
Nonlethal deterrents against carnivores are important components to protecting livestock and conserving carnivore populations. However, the performance of the visual deterrent called fladry, a historical tool used to defend livestock from carnivores, is ...

The Marin County Livestock Protection Program: 15 Years in Review

open access: yesHuman-Wildlife Interactions, 2019
Predation by wild carnivores challenges livestock producers worldwide. To reduce or offset losses due to predation, a variety of predator control methods and compensation schemes have been developed.

Non-lethal control of the cariogenic potential of an agent-based model for dental plaque. [PDF]

open access: yesPLoS ONE, 2014
Dental caries or tooth decay is a prevalent global disease whose causative agent is the oral biofilm known as plaque. According to the ecological plaque hypothesis, this biofilm becomes pathogenic when external challenges drive it towards a state with a ...

The case for case studies: A new approach to evaluating the effectiveness of livestock protection tools

open access: yesCalifornia Fish and Wildlife Journal, 2021
Livestock operations in California face livestock losses due to a range of carnivore species. Simultaneously, there is an increased call to reduce the use of lethal predator control methods and replace them with nonlethal methods. Livestock guardian dogs

Shock collars as a site‐aversive conditioning tool for wolves

open access: yesWildlife Society Bulletin, 2012
Reduction of livestock losses from predators is a complex problem that requires the integration of lethal and nonlethal management tools. During 2005 and 2006, we tested shock collars for conditioning wild wolves (Canis lupus) in Wisconsin, USA, to avoid

Evaluating Lethal and Nonlethal Management Options for Urban Coyotes

open access: yesHuman-Wildlife Interactions, 2017
Human-coyote conflict in urban environments is a growing issue in cities throughout the United States with the primary problem being the development of problem individuals that are overly bold and aggressive with people and pets.

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

open access: yesAdvanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

A new era of wolf management demands better data and a more inclusive process

open access: yesConservation Science and Practice, 2022
Hunting and trapping of gray wolves (Canis lupus) has increased dramatically in the “lower 48” states of the United States. We assess the data used to justify the intense hunting pressure on wolves, and find an absence of accessible biological data.

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...
