Status and Ecological Effects of the World’s Largest Carnivores
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
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.
The Rise of the Mesopredator
An overview of mesopredator release is presented and its underlying concepts can be used to improve predator management in an increasingly fragmented world and it is shown that 60% of mesOPredator ranges have expanded, whereas all apex predator ranges have contracted.
Dynamics and Pattern of a Managed Coniferous Forest Landscape in Oregon
The forest landscape was not in a steady state or regulated condition which is not projected to occur for at least 40 yr under current forest plans, andVariability in cutting rates within ownerships was higher on private land than on nonreserve public land.
Collapse of the world’s largest herbivores
The rate of large herbivore decline suggests that ever-larger swaths of the world will soon lack many of the vital ecological services these animals provide, resulting in enormous ecological and social costs.
Range Contractions of North American Carnivores and Ungulates
Abstract We compared the historic and current geographical ranges of 43 North American carnivores and ungulates to identify large-scale patterns in range contractions and expansions. Seventeen of the…

World Scientists’ Warning to Humanity: A Second Notice
Twenty-five years ago, the Union of Concerned Scientists and more than 1700 independent scientists, including the majority of living Nobel laureates in the sciences, penned the 1992 "World…
Wolves and the Ecology of Fear: Can Predation Risk Structure Ecosystems?
It is indicated that predation risk may have profound effects on the structure of ecosystems and is an important constituent of native biodiversity.
