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

Long-time cartoon sitcom “The Simpsons” announced on Friday that non-white characters will no longer be voiced by white actors.“Moving forward, THE SIMPSONS will no longer have white actors voice non-white characters,” the show said in a statement on Friday.While the main characters on the cartoon are white, there are several characters of color. Most notably, Apu Nahasapeemapetilon, who was voiced by Hank Azaria. In 2018, Azaria said that he would no longer voice the convenience store clerk after the show faced criticism that Nahasapeemapetilon’s character plays up Indian-American stereotypes“The most important thing is, we have to listen to South Asian, Indian people in this country when they talk about how they feel and what they think about this character,” Azaria said on “The Late Show with Stephen Colbert.”Several other minor characters of color on “The Simpsons” include Officer Lou and Carl Carlson, both of whom were also voiced by Azaria.Earlier on Friday, Mike Henry, who voices Black character Cleveland Brown on Fox cartoon sitcom "Family Guy," announced he will no longer voice Brown. "It’s been an honor to play Cleveland on Family Guy for 20 years. I love this character, but persons of color should play characters of color. Therefore, I will be stepping down from the role," Henry said. 1324

LONDON (AP) — Anti-racism protesters in southwestern England have pulled down the statue of a slave trader and then dumped it into a harbor. The toppling of Edward Colston's statue was greeted with joyous scenes Sunday. Demonstrators attached ropes to the statue before pulling it down. Footage of the moments after the statue crashed to the ground saw hundreds, if not thousands, of local residents in ecstasy. The statue was then rolled into the nearby Bristol Harbor. Police said officers have launched an investigation and are looking for those who “committed an act of criminal damage.” 600

LONDON — The British government says it won’t be using 50 million face masks it bought during a scramble to secure protective equipment for medics at the height of the coronavirus outbreak because of safety concerns.The masks were part of a 252 million pound (2 million) contract the government signed with investment firm Ayanda Capital in April. Papers filed in a court case reveal that the masks will not be distributed because they have ear loops rather than head loops and may not fit tightly enough.The government says another 150 million masks supplied by Ayanda are unaffected but are still being tested.The papers are part of a lawsuit against the Conservative government by campaigning groups the Good Law Project and EveryDoctor.As the coronavirus outbreak accelerated across the U.K. in March, it became clear that the country lacked sufficient stockpiles of masks, gloves, gowns and other protective gear for health care workers and nursing home staff. That sparked a race to buy billions of pieces of equipment from suppliers in the U.K. and abroad.Opposition parties are calling for an urgent investigation into the way personal protective equipment was acquired. 1189

LOS ANGELES (AP) — Firefighters struggled Friday to contain a big Southern California wildfire amid shifting winds, forcing authorities to expand evacuations as forecasters extended fire weather warnings into the weekend.The blaze dubbed the Maria Fire erupted late Thursday northwest of Los Angeles during what had been expected to be the tail end of a siege of Santa Ana winds that fanned destructively across the region, but a tug-of-war developed between those offshore gusts and the return of some onshore flow from the ocean."It has been an uphill battle ever since," Ventura County Fire Chief Mark Lorenzen told a midday news conference. "We are finding that the winds are starting to change and that presents its own challenges all by itself."Wind shifts expose new areas of fuel to the fire, bringing "a pretty significant firefight," he said.MAP: CALIFORNIA WILDFIRES 886
