Status and Ecological Effects of the World’s Largest Carnivores
TLDR
The status, threats, and ecological importance of the 31 largest mammalian carnivores globally are reviewed and a Global Large Carnivore Initiative is proposed to coordinate local, national, and international research, conservation, and policy.
Trophic Downgrading of Planet Earth
TLDR
This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles.
PATTERNS OF APPARENT EXTIRPATION AMONG ISOLATED POPULATIONS OF PIKAS (OCHOTONA PRINCEPS) IN THE GREAT BASIN
Abstract We conducted exploratory analyses to examine the relative roles played by natural and anthropogenic influences on persistence of a montane mammal. We revisited historical locations of pikas
The Last Mile: How to Sustain Long‐Distance Migration in Mammals
Abstract:  Among Earth's most stunning, yet imperiled, biological phenomena is long‐distance migration (LDM). Although the understanding of how and why animals migrate may be of general interest, few
Recolonizing Carnivores and Naïve Prey: Conservation Lessons from Pleistocene Extinctions
TLDR
The fact that at least one prey species quickly learns to be wary of restored carnivores should negate fears about localized prey extinction.
Wild horses of the Great Basin
This is the first thorough study of the biology and ecology of American wild horses, a book with insights for all biologists and important implications and recommendations for conservationists and
Rapid ecological and behavioural changes in carnivores: the responses of black bears (Ursus americanus) to altered food
TLDR
The findings suggest alterations in carnivore ecology may be rapid and occur within shorter periods than had been previously assumed.
Fear, human shields and the redistribution of prey and predators in protected areas

TLDR
These findings offer rigorous support that mammals use humans to shield against carnivores and raise the possibility that redistribution has occurred in other mammalian taxa due to human presence in ways the authors have yet to anticipate.
USING BLACK BEARS TO TEST IDEAL-FREE DISTRIBUTION MODELS EXPERIMENTALLY
Abstract Models on the distribution of animals are invaluable in understanding how individuals and, ultimately, populations respond to ecological processes. Rarely, have they been applied to
Global decline in aggregated migrations of large terrestrial mammals
Knowledge of mammal migrations is low, and human impacts on migrations high. This jeopardizes efforts to conserve terrestrial migrations. To aid the conservation of these migrations, we synthesized
