Journal ArticleDOI
Status and ecological effects of the world's largest carnivores.
William J. Ripple,James A. Estes,Robert L. Beschta,Christopher C. Wilmers,Euan G. Ritchie,Mark Hebblewhite,Joel Berger,Bodil Elmhagen,Mike Letnic,Michael Paul Nelson,Oswald J. Schmitz,Douglas W. Smith,Arian D. Wallach,Aaron J. Wirsing +13 more
TL;DR: 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.
Journal ArticleDOI
Predicting ecological consequences of marine top predator declines
TL;DR: The consequences of marine predator declines are outlined and an integrated predictive framework that includes risk effects is proposed, which appear to be strongest for long-lived prey species and when resources are abundant.
Journal ArticleDOI
State‐dependent risk‐taking by green sea turtles mediates top‐down effects of tiger shark intimidation in a marine ecosystem
Michael R. Heithaus,Alejandro Frid,Aaron J. Wirsing,Lawrence M. Dill,James W. Fourqurean,Derek A. Burkholder,Jordan A. Thomson,Lars Bejder +7 more
TL;DR: This study suggests that declines in large-bodied sharks may affect ecosystems more substantially than assumed when non-lethal effects of these top predators on mesoconsumers are not considered explicitly.
Journal ArticleDOI
The ecological effects of providing resource subsidies to predators
Thomas M. Newsome,Thomas M. Newsome,Justin A. Dellinger,Chris R. Pavey,William J. Ripple,Carolyn R. Shores,Aaron J. Wirsing,Chris R. Dickman +7 more
TL;DR: The extent to which human-provided foods are utilised by terrestrial mammalian predators across the globe is reviewed and whether these resources have a direct impact on the ecology and behaviour of predators and an indirect impact on other co-occurring species is assessed.
Journal ArticleDOI
Extinction risk is most acute for the world's largest and smallest vertebrates.
William J. Ripple,Christopher Wolf,Thomas M. Newsome,Michael R. Hoffmann,Aaron J. Wirsing,Douglas J. McCauley +5 more
TL;DR: A global database of body masses for 27,647 vertebrate species indicates that the smallest- and largest-bodied vertebrates have elevated extinction risk, and reveals the vulnerability of large and small taxa, and identifies size-specific threats.
