Making a Mass Anti-Extinction Movement

Pacific Standard, August 9, 2016: With the preceding list as preamble, 43 scientists — mostly ecologists and biologists — took to the pages of the journal BioScience in late July with an audacious appeal: “We must not go quietly into this impoverished future.” The group, led by Oregon State University professor William Ripple, penned a manifesto of sorts to protest the imminent extinction of large carnivores and herbivores the world over.

The World’s Top Predators Are Dining From Dwindling Menus

National Geographic, August 2, 2016: William J. Ripple is an ecologist at Oregon State University who has been studying gray wolves, cougars, and other top predators for decades. Last year, he and his colleagues reviewed the status of the planet’s 31 largest carnivores—a list that includes lions, tigers, and bears, but also sea otters, dingoes, and lynxes. They found that 24 of these animals are in decline, and 17 have been confined to less than half of their original ranges.

Sabercats and Other Carnivores Kept the Ice Age World Green

National Geographic, Dec. 2, 2015: The huge herbivores of the Ice Age were ecosystem engineers. Wherever they went, mastodons, sloths, bison, and their ilk changed the landscape by eating, defecating, trampling, and otherwise going about their plant-mashing business. But they were not isolated agents. Following out the engineer analogy, the megaherbivores of times past had managers. These were the sabercats, hyenas, wolves, and other predators past.
