For GSS Losing Biodiversity chapter 1. Excerpt: ... about seven feet long, nose to tail, and weighed up to 160 pounds. Given a dietary choice, they preferred deer, but would eat almost anything that moved: elk, bighorn sheep, wild horses, beaver, even porcupines. Left free for an evening, they were capable of killing a dozen domestic sheep before dawn, eating their fill and leaving the rest for the buzzards. They were also known to attack humans on occasion. Long ago the Inca called them puma, but today — though they belong to only one species — they have many names. In Arizona they are known as mountain lions; in Florida they are panthers, and elsewhere in the South they are called painters. When they roamed New England, they were called catamounts. In much of the Midwest they are known as cougars, .... All but exterminated east of the Rockies by 1900, they were treated as “varmints” in most Western states until the late ’60s and could be shot on sight. In Maine, the last catamount was killed in 1938. But today Puma concolor is back on the prowl. That is one of the great success stories in wildlife conservation, but also a source of concern among biologists and other advocates, for their increasing numbers make them harder to manage — and harder for people to tolerate. No reliable estimate exists for the cougar population at its lowest point, before the 1970s, but there are now believed to be more than 30,000 in North America. They have recolonized the Black Hills of South Dakota, the North Dakota Badlands and the Pine Ridge country of northwestern Nebraska. ...And as cougars migrate eastward, they are likely to wear out their welcome. People in states unaccustomed to these outsize prowlers will have to answer unpleasant questions: How many livestock and game animals are people willing to lose? How dangerous are cougars to pets and children? How much disruption is a small community willing to endure?.... http://www.nytimes.com/2013/06/11/science/cougars-glamorous-killers-expand-their-range.html. Guy Gugliotta, New York Times.
