LOS BANOS, Calif. (AP) — One of the most recent threats to California's environment has webbed feet, white whiskers, shaggy fur and orange buck teeth that could be mistaken for carrots."Boy, they're an ugly-looking thing," said David Passadori, an almond and walnut grower in central California. "And the way they multiply — jeez."The swamp rodents, called nutria, are setting off alarms in California. They weigh about 20 pounds (9 kilograms) each and eat the equivalent of about a fourth of their weight each day by burrowing into riverbanks and chomping into plants that emerge from the water.The animals can destroy the wetland habitats of rare and endangered species, degrading soil, ruining crops and carrying pathogens that may threaten livestock.Most of all, they pose a public safety risk: Left unchecked, nutria could jeopardize California's water supply, especially if they get into the Sacramento-San Joaquin River Delta.The delta is the "heartbeat of California's water infrastructure," according to Peter Tira, spokesman for the state's Department of Fish and Wildlife. It contains a network of more than 1,000 miles (1,600 kilometers) of canals and levees that protect the area from flooding, provide drinking water to millions of Californians and irrigate the lush agricultural region.Now, armed with million in state funds, the wildlife agency is deploying new tactics to eradicate the nutria and try to prevent the widespread destruction they are known to cause."Over the past two years, our best efforts were trying to not even control the population but keep it from exploding while we pursued the resources needed to actually pursue eradication," said Valerie Cook, environmental program manager for Fish and Wildlife's newly established Nutria Eradication Program."We haven't had nutria in California for 50 years, so nobody really knows much about them," Tira said. "We've had to learn on the job as we go."An invasive species originally from South America and brought to the U.S. at the height of the fur trade in the late 19th century, nutria were believed to have been eradicated in the state in the 1970s until one turned up in a beaver trap in 2017. Since then, more than 700 nutria have been trapped and killed, including four on Passadori's property.Farmers, landowners and biologists in the Central Valley, an agricultural region 130 miles (210 kilometers) north of Sacramento, have been on high alert.On a recent morning in Merced County, where the most nutria have been found, state biologists Greg Gerstenberg and Sean McCain paddled in kayaks in a wetland pond thick with cattails. Wearing waders, they trudged through chest-deep water to check surveillance cameras and cage traps where they leave sweet potato pieces to entice the invasive rodents.Last year, wildlife officials removed almost 90 nutria from this pond. Gerstenberg and McCain have returned because they believe at least a few nutria are back. But on this morning they found only muskrats, smaller swamp-dwelling rodents, and released them back into the pond."Our goal is to get out here and find them and eradicate them before they become fully established throughout our Central Valley," said Gerstenberg, a senior Fish and Wildlife biologist.The Central Valley is the United States' most productive agricultural region, responsible for more than half the nation's fruits, vegetables and nuts, including almost all its apricots, table grapes, carrots, asparagus and tree nuts. Federal Department of Agriculture figures put the market value of Central Valley agricultural production in 2017 at almost billion.Damage to the region's soil or water infrastructure would be devastating to the economy and diet."It would mean no more sushi because the alternative would be to buy rice from Japan or Korea, where the price is five times higher," said Daniel Sumner, director of the Agricultural Issues Center at the University of California-Davis. "Kiss off carrots, or live without table grapes in the summertime."Trail cameras and landowners have helped locate the elusive, nocturnal creatures over an area of almost 13,300 square miles (34,449 square kilometers) that wildlife officials are evaluating for nutria habitats. Live traps baited with sweet potato donated by farmers help capture them. Once identified as nutria, the animals are shot. Tira said about three-quarters of female nutria have been found pregnant — they can have up to three litters a year, allowing them to repopulate quickly.The new attention and funding will allow Fish and Wildlife to hire 46 dedicated staff. By December, the agency will launch what's known as a Judas Nutria program that would outfit surgically sterilized nutria with radio collars and send them out in the wild. Because the animals are so social, they will lead the team to other nutria.Before year's end, Fish and Wildlife will start genetically testing the nutria to determine where they came from. Tira said migration from Oregon or Washington is doubtful, but the team isn't sure whether the nutria were reintroduced to California or part of a remnant population.Taking a cue from Maryland's eastern shore and parts of Delaware and Virginia, officials also will test dogs trained to sniff out the rodents' scent and scat."We can't be successful if we can't find every single animal," Cook said.Besides threatening agriculture and infrastructure, nutria can harm wetlands, which play a critical role in keeping carbon dioxide out of the atmosphere and helping mitigate global warming.The Central Valley also hosts the largest concentration of migratory waterfowl on Earth, said Ric Ortega, the Grassland Water District's general manager."We only have so much surface water storage in California," he said. "It's not a wetland if it's not wet. The nutria complicate that."___Samantha Maldonado reported from San Francisco. 5885

Mental health has been a big concern for many people during the COVID-19 pandemic. Now, more than a month into the new school year, doctors are keeping an eye on teenagers and the difficulties they may be facing as the pandemic continues on."Students are still stressed about what's going to happen next, anxious about mixed information they may hear on the news, they may hear on social media, they may hear from their friends in school and they're just trying to figure out what’s going to happen and how long is this going to last and when are things going to get back to normal," says Dr. Christina Conolly, a school psychologist and members of the National Association of School Psychologists.Dr. Conolly says some students are now grappling with anxiety and depression along with the added stress of school.There could be lasting effects on some teenagers who have been isolated for so long."Potentially, I would say not just for teenagers, but for young children and adults, as well. We’ve not experienced an event like this since the pandemic in the early 1900s," says Dr. Conolly.Mental health officials at schools are honing in on children and teens who might be vulnerable and in need of someone to talk to. Dr. Conolly says her school is even launching a new program centered around students' social and emotional wellbeing."In my school district, we have developed student well-being teams at all of our schools. We have referral forms for teachers to go and refer students who are in need of support. We’ve been doing what we call student psychoeducational lessons for all of our students pre-K through 12th grade," says Dr. Conolly.Stress management and mental health is a priority for Parker Pediatrics and Adolescents in Colorado. Pediatrician Dr. Brian Stanga conducts mental health screenings with all patients when they come in for a check-up."We ask them about things like stress level, stress and then if so, how many days a week are they feeling stressed? Is it greatly impacting their quality of life or not greatly impacting their quality of life," says Dr. Stanga.The pediatric practice also has four child and adolescent psychologists on staff. In March, pediatrician visits were down 50% but psychologist visits remained at 100% of normal."One of our core mission statements is we believe in the whole child, whether physical, mental and emotional health. It is all intertwined and that’s pretty clear from a lot of studies. If you're stressed, it elevates your heart rate, your blood pressure, all those things which in then affects your physical health," says Dr. Stanga.So what can parents do to help guide their teens and younger children through this stressful time?"Finding something that you all enjoy that you can do as a family. Talk with each other, have dinner with each other. I know some of these are things people hear and sound a little corny but these are truly things that can help," says Dr. Conolly.Dr. Conolly says educating parents about substance abuse and suicide prevention is also key right now. Ensuring students' mental needs are met and they have positive outlets to turn to when the world around them seems lost. 3177

MIAMI (AP) — President Donald Trump is postponing his planned rally Saturday in New Hampshire citing a tropical storm threatening parts of the mid-Atlantic and southern New England.Press secretary Kayleigh McEnany tells reporters traveling with the president Friday to Florida that the event — slated to be held in an aircraft hangar in Portsmouth — will be delayed by a week or two.She cited the threat of Tropical Storm Fay, which is expected to bring heavy rain to the region.The event was to mark Trump’s first political rally in three weeks, after his return to his signature campaign events from a coronavirus-induced hiatus was overshadowed by an embarrassing display of empty seats and questions about the campaign’s ability to attract people to large events in a pandemic. 789

MACOMB TOWNSHIP, Mich. — A Michigan model for American Girl Dolls is opening up about her health. Alyea Rourke, who has modeled as the Hawaiian American Girl doll Nanea Mitchell, says she's been diagnosed with a disease so rare it took nearly two years to diagnose."It seemed like a giant dream to me. I was just so scared I immediately thought I will never be able to skate again," the now 14-year-old said.Alyea was diagnosed with chronic recurrent multi-focal osteomyelitis (CRMO), a potentially serious and unique form of bone disease that can be long-lasting. Right now, there's no known cure, doctors say. "They described to us was possibly an ear issue, or it was an infection in the jaw or it could’ve been a tooth decay or something like that. So we went probably through about seven doctors before we got an answer," said Lynda Rourke, Alyea's mother. Despite the pain affecting her ability to skate and chance to live a regular teen life, the 14-year-old has tried to stay positive. "I'm not letting it stop me from skating and doing what I love," she said.Alyea's family has set up a GoFundMe?account for support with medical expenses.  1216

Millions of people are still unemployed in the United States. On one hand, the unemployment rate has been going down since its peak in June. On the other hand, it’s still almost triple what it was before the pandemic.“I just never anticipated this is where we would be in September,” said Bridget Altenburg, president of the National Able Network.For 40 years, the National Able Network has been helping people find work. But in the past six months, it has been working overtime on that. The organization has been getting roughly 100 calls for employment help a day, serving more than 10,000 people since March.“It is scary for the people that we are talking to,” said Altenburg. “It’s scary for them because we thought it would be a month or two months of unemployment, and here we are, basically six months later, trying to help people navigate who’s hiring.”Altenburg has two key pieces of advice for anyone unemployed right now. One, she is emphatic that there are employers out there hiring.“There are employers that are desperate for people,” said Altenburg. “So, don’t immediately assume that there is nothing out there, so I might as well not look.”Secondly, Altenburg recommends anyone unemployed take a moment to figure out potential jobs in current high-demand fields and think creatively about how your current skill sets apply to those potential jobs.“Don’t sell yourself short in terms of what makes you uniquely qualified for that role,” she added.For example, you wouldn’t think of a restaurant worker having a unique skill set to be a good fit in the IT field, but the National Able Network has been training them to switch over and IT employers are flocking to recruit these workers.“People who have been servers intuitively know customer service in a way that I could never teach somebody that is in IT,” Altenburg explained.In addition to the National Able Network, there is also about 2,400 government-funded American Job Centers nationwide offering free career and job hunt services. In addition, most public libraries, even many community colleges, are offering free resume and some career services help as well.“At Lyft, when we think of the way we can make on communities, we think about how we can use transportation to do so,” said Lisa Boyd with Lyft.The ride-share company has even jumped in to help the millions on the job hunt. It is providing free rides, now in 20 cities, to people going to and from job interviews, job training, and even free rides to work until they get their first paycheck at their new job.The program started in 2019, but at the beginning of the pandemic, Lyft expanded it to help with the increased need.“We have a job access hub on our Lyft website,” said Boyd. “That will help you be able to go in and sign up on a form.”Anyone in need of the free ride while you job hunt or start a new job can go to Lyft's Job Access Page on its website. All you have to do is provide info on where you live, what kind of help you need, and the site will connect you with your local United Way or Goodwill. The two partner organizations actually distribute Lyft’s free rides, and they both offer additional free career services help. 3184
