Southern California sagebrush better suited to climate change, study finds

Apr. 1, 2013 ? California sagebrush in the southern part of the state will adjust better to climate change than sagebrush populations in the north, according to UC Irvine researchers in the Department of Ecology & Evolutionary Biology affiliated with the Center for Environmental Biology.

The results of their study, which appears online in Global Change Biology, will assist land management and policy decisions concerning coastal sage scrub restoration.

California sagebrush (Artemisia californica), also known as "cowboy cologne," is the fragrant gray-green shrub that once filled area ranch land. It's found on coastal hillsides for more than 400 miles along California's Pacific coast. Only about 10 percent of its original habitat remains -- the rest having been converted to human use -- and is home to a number of endangered species, including the California gnatcatcher, which depend on plants like sagebrush.

In their study, Jessica Pratt and Kailen Mooney transplanted sagebrush from sites up and down the California coast to a test garden near UC Irvine to see which shrubs were best able to withstand particular environmental challenges. They measured the differences in plant traits and responses to experimentally altered precipitation.

The researchers found that populations from southern sites, with historically variable rainfall amounts, adjusted with greater ease to altered precipitation than did populations from the historically invariant north. Accordingly, they asserted, reaction to climate change will differ across this species's range, with southern populations adapting more readily to future conditions.

"For instance, sagebrush from San Diego stretches, where precipitation varies substantially from year to year, were better able to respond to changes in precipitation than those from the San Francisco area," said Mooney, an assistant professor of ecology & evolutionary biology.

He and Pratt also analyzed long-term climate data from along the California coast and discovered that year-to-year variability in rainfall has been increasing.

Taken together, these findings suggest that it might be prudent to plant Southern California sagebrush on Northern California hillsides to compensate for this heightened fluctuation in precipitation.

Taxpayers and private donors currently spend millions trying to properly manage the remnants of coastal sage scrub and other diverse habitats that remain on public and private land. Pratt and Mooney hope to determine which strategies are most effective for the least cost.

"This work addresses basic issues in ecology in an applied framework that will be immediately useful in informing land management and policy decisions for coastal sage scrub restoration," said Pratt, a Ph.D. candidate in ecology & evolutionary biology. "Understanding the responses of important species to environmental change -- and how those responses scale up to affect other species -- will help us predict and mitigate the impacts."

The study received support from the Newkirk Center for Science & Society, the UC Irvine Graduate Division (through a 2011-12 Public Impact Fellowship), the Orange County Association of Environmental Professionals, the Newport Bay Conservancy and the Lake Forest Garden Club, as well as grants from the National Science Foundation and the Environmental Protection Agency.

The Center for Environmental Biology at UC Irvine links academic research and education with ecosystem management, stewardship of natural resources and sustainability efforts throughout Southern California.

Afghan teenager fatally stabs U.S. soldier

KABUL, Afghanistan (AP) ? Senior U.S. military officials say an Afghan teenager has killed an American soldier in eastern Afghanistan by stabbing him in the neck.

Two officials said Monday that Sgt. Michael Cable, 26, was guarding a meeting of Afghan and U.S. officials in Nangarhar province when the stabbing occurred.

One of the officials estimated the attacker was 16 years old, but he escaped so the age couldn't be verified.

The official says the youth was not believed to be from the Afghan security forces so the Wednesday stabbing is not being classified as an insider attack.

Both officials spoke on condition of anonymity because the investigation is ongoing.

The Pentagon said in a statement last week that Cable died from injuries sustained when his unit was attacked by enemy forces.

(AP) ? Hundreds of patients of an Oklahoma oral surgeon accused of unsanitary practices showed up at a health clinic Saturday, looking to find out whether they were exposed to hepatitis or the virus that causes AIDS.

Letters began going out Friday to 7,000 patients who had seen Dr. W. Scott Harrington during the past six years, warning them that poor hygiene at his clinics created a public health hazard. The one-page letter said how and where to seek treatment but couldn't explain why Harrington's allegedly unsafe practices went on for so long.

Testing for hepatitis B, hepatitis C and the virus that causes AIDS began at 10 a.m. Saturday, but many arrived early and stood through torrential downpours. The Tulsa Health Department said 420 people were tested Saturday at its North Regional Health and Wellness Center. Screenings resume Monday morning.

Kari Childress, 38, showed up at 8:30 a.m., mainly because she was nervous.

"I just hope I don't have anything," said Childress, who had a tooth extracted at one of Harrington's two clinics five months ago. "You trust and believe in doctors to follow the rules, and that's the scariest part."

Inspectors found a number of problems at the doctor's clinics in Tulsa and suburban Owasso, according to the state Dentistry Board, which filed a 17-count complaint against Harrington pending an April 19 license revocation hearing. According to the complaint, needles were reinserted into drug vials after being used on patients, expired drugs were found in a medicine cabinet and dental assistants, not the doctor, administered sedatives to patients.

One patient, Orville Marshall, said he didn't meet Harrington until after he had two wisdom teeth pulled about five years ago at the Owasso clinic. A nurse inserted the IV for his anesthesia; Harrington was there when Marshall came to.

"It's just really scary. It makes you doubt the whole system, especially with how good his place looked," said Marshall, 37.

An instrument set reserved for use on patients with infectious diseases was rusty, preventing its effective sterilization, and the office autoclave ? a pressurized cleaner ? was used improperly and hadn't been certified as effective in at least six years, according to the complaint.

Dr. Matt Messina, a Cleveland dentist and a consumer adviser for the American Dental Association, said creating a safe and hygienic environment is "one of the fundamental requirements" before any dental procedure can be performed.

"It's not hard. It just takes effort," he said.

Weekly autoclave testing can be performed for less than $400 annually, according to the website of the Autoclave Testing Services of Pearl River, New York.

Autoclaves typically can be purchased for $1,000 to $8,000, depending on their size and features. And an average dental practice can expect to pay more than $40,000 a year in equipment, tools and supplies alone, according to several dental organizations.

Attempts to reach Harrington have been unsuccessful. No one answered the door Thursday at his Oklahoma home, which property records show is worth more than $1 million. His practice a few miles away, in a tony section of Tulsa where plastic surgeons operate and locals congregate at bistros and stores such as Saks Fifth Avenue, has a fair-market value of around $851,000.

Property and tax records show Harrington owns another residence in Carefree, Ariz., in an area of upscale homes tucked into in the boulder-strewn mountains north of Phoenix.

Nobody was at home Saturday at the low-slung, 1950s-style vacation home, across from the Boulders Resort. Neighbors said they had seen a lot of activity at the home in recent weeks.

Harrington's malpractice lawyer, Jim Secrest II, did not respond to phone messages left Thursday or Friday. A message at Harrington's Tulsa office said it was closed and an answering service referred callers to the Tulsa Health Department.

Suzy Horton, an old friend of Harrington's, said she can't believe the allegations about the man who removed two of her teeth in the early '90s. Horton's ex-husband sold Harrington his home in Carefree ? a home where she once lived.

"I've been to dentists my whole life, so I know what a professional office looks like," Horton, who now lives in Phoenix, said in a telephone interview. "His was just as professional as anybody."

Horton hasn't seen Harrington in years, but she said he has sent her a Christmas card and wreath every year since her 1999 divorce.

"It was a long time ago, so I suppose anything can change, but the kind of person they're portraying in the news is not the kind of person who sends you a Christmas" card, she said.

Bank of Cyprus big savers to lose up to 60 percent

NICOSIA, Cyprus (AP) ? Big depositors at Cyprus' largest bank may be forced to accept losses of up to 60 percent, far more than initially estimated under the European rescue package to save the country from bankruptcy, officials said Saturday.

Deposits of more than 100,000 euros ($128,000) at the Bank of Cyprus will lose 37.5 percent in money that will be converted into bank shares, according to a central bank statement. In a second raid on these accounts, depositors also could lose up to 22.5 percent more, depending on what experts determine is needed to prop up the bank's reserves. The experts will have 90 days to figure that out.

The remaining 40 percent of big deposits at the Bank of Cyprus will be "temporarily frozen for liquidity reasons," but continue to accrue existing levels of interest plus another 10 percent, the central bank said.

The savings converted to bank shares would theoretically allow depositors to eventually recover their losses. But the shares now hold little value and it's uncertain when ? if ever ? the shares will regain a value equal to the depositors' losses.

Emergency laws passed last week empower Cypriot authorities to take these actions.

Cyprus' Finance Minister Michalis Sarris said the measures were taken to put the Bank of Cyprus on a solid footing.

"We suffered a serious blow without doubt ... but we now have a bank which is reformed and ready to assume its role in the Cypriot economy," the state-run Cyprus News Agency quoting him as saying.

Analysts said Saturday that imposing bigger losses on Bank of Cyprus customers could further squeeze already crippled businesses as Cyprus tries to rebuild its banking sector in exchange for the international rescue package.

Sofronis Clerides, an economics professor at the University of Cyprus, said: "Most of the damage will be done to businesses which had their money in the bank" to pay suppliers and employees. "There's quite a difference between a 30 percent loss and a 60 percent loss." With businesses shrinking, Cyprus could be dragged down into an even deeper recession, he said.

Clerides accused some of the 17 European countries that use the euro of wanting to see the end of Cyprus as an international financial services center and to send the message that European taxpayers will no longer shoulder the burden of bailing out problem banks.

But German Finance Minister Wolfgang Schaeuble challenged that notion, insisting in an interview with the Bild daily published Saturday that "Cyprus is and remains a special, isolated case" and doesn't point the way for future European rescue programs.

Europe has demanded that big depositors in Cyprus' two largest banks ? Bank of Cyprus and Laiki Bank ? accept across-the-board losses in order to pay for the nation's 16 billion euro ($20.5 billion) bailout. All deposits of up to 100,000 are safe, meaning that a saver with 500,000 euros in the bank will only suffer losses on the remaining 400,000 euros.

Cypriot officials had previously said that large savers at Laiki ? which will be absorbed in to the Bank of Cyprus ? could lose as much as 80 percent. But they had said large accounts at the Bank of Cyprus would lose only 30 to 40 percent.

Asked about Saturday's announcement, University of Cyprus political scientist Antonis Ellinas predicted that unemployment, currently at 15 percent, will "probably go through the roof" over the next few years.

"It means that (people) ... have to accept a major haircut to their way of life and their standard of living. The social impact is yet to be realized, but they will be enormous in terms of social unrest and radical social phenomenon," Ellinas said.

There's also concern that large depositors ? including many wealthy Russians ? will take their money and run once capital restrictions that Cypriot authorities have imposed on bank transactions to prevent such a possibility are lifted in about a month.

Sarris, the finance minister, said that foreign branches of the Bank of Cyprus and Laiki Bank in countries such as Britain, Russia, Ukraine and Romania will eventually be sold. He also said that Cypriots would seek out new markets like China and the Arab countries while maintaining good business relations with Russians, "despite their bitterness."

Cyprus agreed on Monday to make bank depositors with accounts over 100,000 euros contribute to the financial rescue in order to secure 10 billion euros ($12.9 billion) in loans from the eurozone and the International Monetary Fund. Cyprus needed to scrounge up 5.8 billion euros ($7.4 billion) on its own in order to clinch the larger package, and banks had remained shut for nearly two weeks until politicians hammered out a deal, opening again on Thursday.

But fearing that savers would rush to pull their money out in mass once banks reopened, Cypriot authorities imposed a raft of restrictions, including daily withdrawal limits of 300 euros ($384) for individuals and 5,000 euros for businesses ? the first so-called capital controls that any country has applied in the eurozone's 14-year history.

The rush didn't materialize as Cypriots appeared to take the measures in stride, lining up patiently to do their business and defying dire predictions of scenes of pandemonium.

Under the terms of the bailout deal, the country' second largest bank, Laiki ? which sustained the most damaged from bad Greek debt and loans ? is to be split up, with its nonperforming loans and toxic assets going into a "bad bank." The healthy side will be absorbed into the Bank of Cyprus.

On Saturday, economist Stelios Platis called the rescue plan "completely mistaken" and criticized Cyprus' euro partners for insisting on foisting Laiki's troubles on the Bank of Cyprus.
