LOS ANGELES (CNS) - Newly published research indicates there's an almost one-in-four chance the mountain lions living in the Santa Monica and Santa Ana mountains could become extinct in those areas within 50 years as a result of urban encroachment, inbreeding, vehicle strikes, rat poison and wildfire, it was reported today.In the face of such a dire prognosis, what biologists call an extinction vortex, conservationists are considering a desperate and controversial remedy: capturing pumas in one part of the Santa Anas and trucking them across the 15 Freeway so that they can breed with isolated mates on the other side of traffic."Wildlife managers never want to be a shuttle service for wild animals,'' said Justin Dellinger, senior environmental scientist with the Wildlife Investigations Laboratory at the California Department of Fish and Wildlife, the Los Angeles Times reported. But translocation has potential merit in the short term; after all it helped bring the critically endangered Florida panther back from the brink.Mountain lions are not endangered in California, but groups living in the Santa Monica and Santa Ana ranges now find themselves in genetic peril. Separated by freeways and lethal traffic, they are unable to range freely and are growing increasingly inbred, researchers say.In the Santa Monica Mountains, the 101 Freeway exists as a near impenetrable barrier to gene flow for a group of 10 mountain lions; in the Santa Ana Mountains, the 15 Freeway limits the movement of a family of 20 cougars.Sometimes, the animals manage to cross freeways without getting hit. At least seven cougars have crossed the 15 Freeway near Temecula in the last 15 years, and one sired 11 kittens. The fact that only one managed to reproduce, however, shows how difficult it is to diversify the gene pool in the lions still prowling the range.A population viability study published in the journal Ecological Applications predicts extinction probabilities of 16 to 28 percent over the next 50 years for these lions, which have the lowest genetic diversity documented for the specie aside from the critically endangered Florida panther.Study authors note also that wildfire and disease could result in "catastrophic mortality'' and further hasten the animals' disappearance.However, extinction probabilities were significantly reduced when computer models simulated the influence of two immigrant lions per year in areas blocked by development and freeways, according to a team of researchers that included Winston Vickers, an associate veterinarian at the UC Davis Karen C. Drayer Wildlife Health Center, and Seth Riley, an ecologist with the Santa Monica Mountains National Recreation Area, The Times reported. 2731

LONDON (AP) — Cinema chain Cineworld says it is considering closing all its movie theaters in Britain and the United States, after the postponement of the new James Bond film left a big hole in schedules. Cineworld Group PLC owns 543 Regal cinemas in the U.S. and 128 Cineworld venues in the U.K. and Ireland. It said Sunday it was "considering the temporary closure of our U.K. and U.S. cinemas, but a final decision has not yet been reached." The statement came after the Sunday Times reported that Cineworld's U.K. theaters will shut in the coming weeks. The release of James Bond thriller "No Time to Die" has been delayed from November until April 2021 because of the effect of the coronavirus pandemic. 716

LONDON (AP) — John le Carre, a spy turned novelist who became the preeminent writer of espionage fiction in English, has died at the age of 89.Le Carre’s literary agency, Curtis Brown, said Sunday that he died in Cornwall, southwest England on Saturday after a short illness.His family said he died of pneumonia and the death was not related to COVID-19.Born David Cornwell, le Carre worked for Britain’s intelligence service before turning his experience into fiction in works, including “Tinker Tailor Soldier Spy” and “The Spy Who Came in from the Cold.”In the quiet, watchful spymaster George Smiley, he created one of 20th-century fiction’s iconic characters — a decent man at the heart of a web of deceit. 719

LOS ANGELES (AP) -- California authorities sent a cellphone text alert to two major regions of the state to tell millions of people that the coronavirus is spreading rapidly and ask them to stay home except for essential activities.The Tuesday noon blast to the state-designated 11-county Southern California region -- which includes San Diego County -- and 12-county San Joaquin Valley region was sent by the Office of Emergency Services.The text also urged people to wear masks and physically distance.RELATED: New COVID-19 stay-at-home order takes effect in San Diego CountyBoth regions came under increased restrictions this week after the total capacity of hospital intensive care units dropped below 15%.The restrictions will remain in effect for at least three weeks. 782
