New research suggests nature-based solutions – such as wetland and floodplain restoration—can improve water quality and increase flood resiliency in the Champlain Basin.  

The study finds that Vermont can achieve 15% of its phosphorous reduction goals in Lake Champlain by restoring degraded wetlands. These investments in natural solutions are likely to be less expensive than the cost of projected future flood damage, researchers say. 

The findings result from a new partnership between The Nature Conservancy in Vermont and the Gund Institute for Environment at UVM, which seeks to quantify how nature-based solutions can address water quality and flooding.

In Vermont, 35% of wetlands have been converted to farmland or lost to development. While wetlands have historically been considered unproductive lands, they – and floodplain forests – naturally filter out pollution sources like sediment and agricultural and storm water run-off.

“As a society we often try to fix environmental problems with engineered solutions, when often the most effective and affordable tool we have at our disposal is nature itself,” says Rose Paul, director of science and freshwater programs for The Nature Conservancy in Vermont. “As we struggle with our water quality issues in Vermont, we want to highlight the importance of investing in our wetlands and floodplains to address some of our most vexing issues.” 

“We are excited to partner with the Nature Conservancy, using leading-edge science to help manage our natural infrastructure in ways that support Vermont’s communities and economy,” says Taylor Ricketts, director of the Gund Institute for Environment. “Further research will help Vermont leaders to identify which wetlands can provide the greatest reductions in phosphorus and flood risk at the lowest cost.” 

The partnership has already produced important discoveries. In a new study in Environmental Research Letters, Gund researchers offer a new model to prioritize wetlands for restoration, and find that restoring smaller wetlands, close to stream networks, offers the greatest reduction in nutrient pollution in relation to cost. In a previous study in Science of the Total Environment, they also found that reconnecting and re-vegetating floodplains reduces stream power during floods. 

Researchers now seek to pair phosphorus data and restoration costs with individual wetlands in Vermont to better prioritize and direct wetland investment decisions. Additional research will explore how much phosphorus is trapped on floodplains during high water events, which types of floodplains make the greatest contribution to flood resilience and water quality, and the cost-effectiveness of floodplain restoration compared to the cost of projected future flood damage. 

“Science is leading the way in acknowledging the role of nature in addressing our 21^stcentury environmental problems,” said Heather Furman, state director for The Nature Conservancy in Vermont. “Our research partnership with Gund is advancing this work by helping us measure the impacts of wetlands and floodplains to support healthier and more resilient communities through conservation.” 

The Nature Conservancy and the Gund Institute are committed to making their research available to the public, partner organizations, policy makers and state agencies to inform best practices and advance solutions for environmental challenges in Vermont and around the world.

When Jose Calderon was six years old, his mother began exhibiting symptoms of schizophrenia. As he watched her cycle in and out of psychiatric units – sometimes enduring run-ins with law enforcement and negative encounters with neighbors and members of their church – he came to understand how the stigma associated with mental illness can devastate a family already struggling to cope with a brutal disease.   

Years later, fresh out of high school, he joined the U.S. Marine Corps and went on to serve two tours of duty, one a combat mission in Afghanistan. Peers were killed in action, and others returned home only to suffer through post-traumatic stress disorder. 

These two seminal experiences helped to propel him on a career path that led to UVM’s Larner College of Medicine. “I’m a first-generation college student, first-generation medical school student,” he says. “I came here fresh and with an open mind, willing to adapt and overcome.” 

It wasn’t an easy path: Growing up in a low-income neighborhood in Houston touched by crime and gang violence, there weren’t many role models. His father instilled in his three children a love of learning and a strong work ethic, despite his own education in El Salvador ending at the third-grade level.

“I remember him expecting us to have our homework done by 8 p.m,” he says. “It was a matter of being accountable to ourselves. He really valued education.”

Calderon’s father came to the U.S. from El Salvador as a teenager, desperate to escape the vicious civil war unfolding in that country. He found work as a construction worker and met Calderon’s mother, also a native of El Salvador, in Houston. Calderon’s first language was Spanish; he learned English when he entered elementary school. His older twin brothers helped to keep Calderon focused on achieving his goals. 

“It was a challenging childhood,” he says. “I owe a lot to them being on the right path, and me trying to emulate them.”

Calderon’s decision to enter the Marine Corps was a tough one for his father, who, after witnessing the devastation war brought to his home country, struggled to understand why his youngest child would volunteer to put himself in harm’s way. 

But Calderon says his military service gave him courage and confidence. On his first tour of duty, he traveled around the world, improving military training and tactics while also conducting humanitarian missions in far-flung locations like East Timor, Thailand, Djibouti, and Kuwait. As he painted primary schools alongside local residents and helped to distribute potable water, he realized just how much he had to contribute, especially in communities with the greatest need. 

Serving in Afghanistan strengthened his resolve to make a difference. 

“I think you’re forced to mature at a young age,” he says. “You learn to value life differently than others at that age. It’s a powerful experience, being there and doing your best to handle stressful situations.”

His time in a combat zone also gave him a window into the medical field. He remembers a time when his unit was being hit particularly hard by enemy fire, and personnel were asked to gather at a medical site to give blood. As he waited, an injured Marine arrived by helicopter. A roadside bomb had exploded while he was on patrol with his platoon; he had suffered traumatic injuries including three amputated limbs. Calderon remembers the seamless communication and sharp decision-making of the surgical team as they saved the Marine’s life. Watching those surgeons work was key to sparking his interest in medicine, he says. 

After his four years of military service, Calderon studied psychology at the University of Southern California. A minor in healthcare studies, an assistantship in USC’s Culture and Mental Health Research Lab and volunteer work in the emergency department at L.A. County General Hospital in East Los Angeles all helped him prepare for the career he envisioned.

The decision to come to UVM’s Larner College of Medicine was based in part on the school’s mission statement and emphasis on active learning in medical education, but even more on the sense of community he experienced when he visited the campus and Burlington.

Although he has yet to decide on a specialty – he’s considering psychiatry, family medicine and emergency medicine – Calderon is committed to serving where he is needed the most. “I want to work in an underserved, low-income, urban community, and I want to work with a Spanish speaking population,” he says. “I think I can make the biggest impact there.”

David Tomasi didn’t reinvent the wheel with his latest research on exercise; in fact, he’s well aware that the core concept has been common knowledge for centuries. “The Romans used to say: ‘Mens sana in corpore sano,’” he recites in his native language, Italian, “which means ‘healthy mind, healthy body.’” But what he is proposing is a new application for the tried-and-true wheel.

A lecturer at UVM and inpatient psychotherapist at UVM Medical Center, Tomasi notes that the number of psychiatric patients seeking acute, inpatient treatment has steadily increased since the ’90s at the start of the opioid crisis. A majority of the patients he treats at UVMMC are young adults suffering from dual-diagnoses of a mood disorder and addiction, typically to opioids. According to Mental Health Care America, Vermont is ranked the sixth most prevalent state for mental illness and substance disorders.

“There aren’t enough beds. We have struggles with opioid addiction and suicidality, and it’s a crisis we’ve never seen before on a national level in the United States. Especially in the northeast, especially in New England, but even more so in Vermont. We are really struggling,” he says. 

In Tomasi’s line of work, inpatient facilities across the nation are often crowded, acute settings where patients experience severe distress and discomfort. When patients display symptoms like mania, angry outbursts, anxiety, or disruptive behavior, practitioners primarily prescribe psychotropic medications or rely on classical psychotherapeutic and pharmacological frameworks. To keep the revolving door in motion for the next patient, practitioners determine if or when patients are ready for discharge once their symptoms subside.

At UVMMC, where Tomasi and his colleagues Sheri Gates and Emily Reyns treat patients suffering from a range of mood and mental health disorders like dual-diagnoses, critical anxiety, depression, schizophrenia, suicidality and acute psychotic episodes, a new idea surfaced: What if practitioners prescribed patients exercise as part of their treatment plans?

To explore the potential of this mind-body connection, Tomasi, Gates and Reyns were awarded an inaugural University of Vermont Medical Center Fund grant that supported their study and enabled them to build a gym, exclusive to patients in UVMMC’s inpatient psychiatry unit. For roughly 100 patients in the unit, treatment plans included new 60-minute nutrition education programs and structured exercise classes that featured a combination of relaxation, stretching, and exercise techniques recommended by the American College of Sports Medicine, “all monitored by psychotherapists — that’s the key. We were always there to support the emotional background as well,” Tomasi says. They surveyed patients on their mood, self-esteem and self-image both before and after the exercise sessions to gauge their effects on mood.

Given that benefits of exercise have long been known and studied, Tomasi admits that he and his team anticipated positive results. But what they found surprised even them: a whopping 95 percent of patients reported that their moods improved after doing the structured exercises. While nearly all patients reported an improvement in their general mood, an average of 63 percent of patients reported being happy or very happy after the exercises, as opposed to neutral, sad or very sad, and an average of 91.8 percent of patients reported that they were pleased with the way their bodies felt after doing the structured exercises. Overall, patients reported reduced levels of mood disorder symptoms like anger, anxiety and depression and higher levels of self-esteem and improved moods.

“The general attitude of medicine is that you treat the primary problem first, and exercise was never considered to be a life or death treatment option. Now that we know it’s so effective, it can become as fundamental as pharmacological intervention,” Tomasi says. “The fantastic thing about these results is that, if you’re in a psychotic state, you’re sort of limited with what you can do in terms of standard psychotherapy. It’s hard to receive a message through talk therapy in that state, whereas with exercise, you can use your body and not rely on cognitive or emotional intelligence alone.”

Unfortunately, Tomasi estimates that only a handful of inpatient psychiatric hospitals in the United States provide psychotherapist-supported gym facilities exclusively for these patients or incorporate structured exercise classes into patient treatment plans. In the midst of a national opioid epidemic, Tomasi argues that there’s never been a better time to try and reduce patients’ potential reliance on prescription psychotropic medications and promote a more balanced, integrated sense of self.

A Look Inside the Brain

As Tomasi points out, even the ancient Romans knew that exercise makes both our bodies and minds feel better. But what he, Gates and Reyns have found helps lay the groundwork for further evidence-based research about exercise’s ability to treat mental health and mood disorder symptoms naturally. While this phase of their study relied on self-reporting and evaluation by patients themselves — which Tomasi argues is one of the most important factors in psychiatry, to hear a patient say they’re feeling better — the next phase of their research will incorporate brain scans and MRI analysis to confirm what they expect is happening: exercise is balancing the brain’s chemicals naturally.

“You experience a level of neurofeedback, in which the thing you are doing makes you feel that you’re doing the right thing and so the body, in turn, secretes neurotransmitters and makes you feel happier about it,” Tomasi explains.

Prior research has proven that when exercise occurs, the brain stimulates the nervous system — which releases neurotransmitters like serotonin and dopamine, targeted in the treatment of depression — as well as the endocrine system, which regulates hormones that impact everything from mood to metabolism. The specific combination of neurotransmitters and hormones released during exercise can reduce symptoms of anxiety, depression, anger, psychomotor agitation and muscle tension.

“We definitely overmedicate folks in this country, period. No doubt about it. Then on top of that, the medication that we put into the brain — neurologically speaking — is already produced by the brain. So, it’s not that patients would be opting out of medication, they’d be increasing the level of those same neurotransmitters naturally, through exercise, as opposed to chemically,” he explains.

Finding Balance 

Tomasi understands that medication is necessary for some patients. By no means is he advocating for practitioners to replace their prescription pads with gym memberships. Instead, what he hopes patients and practitioners alike will consider are the ways in which the mind and body work in tandem, as well as holistic approaches to maintaining mental and physical health that reduce reliance on psychotropic medications alone. 

“For instance, in Italy when I’m from, there is no psychiatric hospital. By law, there is no inpatient psychiatry, period,” he says, illuminating the stark contrasts in approaches to mental health. “There, mental health is considered to be a social issue, so if you’re experiencing a psychotic episode, the community, the town or the city is responsible for your wellbeing. In Scandinavia, they have this open dialogue model in which the patient is part of every decision-making meeting, giving calls and providing feedback.”

In Vermont, Tomasi notes that a balanced and integrated approach to mental health is very much in the DNA of the state and could be just what the doctor ordered. Based on the study’s positive results, Tomasi believes that incorporating American College of Sports Medicine-approved exercises into inpatient treatment would not only improve patients’ symptoms faster than classic pharmacological intervention alone could — thus increasing facilities’ bed and patient turnover rates — but would also offer patients an alternative, holistic, and cost-effective approach to maintaining their mental health after discharge.

“It’s something that we know, deep inside, to be effective, and the time is ripe for that,” he says. “I think Vermont, especially UVM, is going to be a leader in this field.”

A Noah’s Ark strategy will fail. In the roughest sense, that’s the conclusion of a first-of-its-kind study that illuminates which marine species may have the ability to survive in a world where temperatures are rising and oceans are becoming acidic.

Two-by-two, or even moderately sized, remnants may have little chance to persist on a climate-changed planet. Instead, for many species, “we’ll need large populations,” says Melissa Pespeni, a biologist at the University of Vermont who led the new research examining how hundreds of thousands of sea urchin larvae responded to experiments where their seawater was made either moderately or extremely acidic.

The study was published on June 11, 2019, in the Proceedings of the Royal Society B.

Rare relief

Pespeni and her team were surprised to discover that rare variation in the DNA of a small minority of the urchins were highly useful for survival. These rare genetic variants are “a bit like having one winter coat among fifty lightweight jackets when the weather hits twenty below in Vermont,” Pespeni says. “It’s that coat that lets you survive.” When the water conditions were made extremely acidic, these rare variants increased in frequency in the larvae. These are the genes that let the next generation of urchins alter how various proteins function—like the ones they use to make their hard-but-easily-dissolved shells and manage the acidity in their cells.

But maintaining these rare variants in the population—plus other needed genetic variation that is more common and allows for response to a range of acid levels in the water—requires many individuals.

“The bigger the population, the more rare variation you’ll have,” says Reid Brennan, a post-doctoral researcher in Pespeni’s UVM lab and lead author on the new study. “If we reduce population sizes, then we’re going to have less fodder for evolution—and less chance to have the rare genetic variation that might be beneficial.”

In other words, some organisms might persist in a climate-changed world because they’re able to change their physiology—think of sweating more; some will be able to migrate, perhaps farther north or upslope. But for many others, their only hope is to evolve—rescued by the potential for change that lies waiting in rare stretches of DNA.

Rapid adaptation

The purple sea urchins the UVM team studied in their Vermont lab are part of natural populations that stretch from Baja, California to Alaska. Found in rocky reefs and kelp forests, these prickly creatures are a favorite snack of sea otters—and a key species in shaping life in the intertidal and subtidal zones. Because of their huge numbers, geographic range, and the varying conditions they live in, the urchins have high “standing genetic variation,” the scientists note. This makes purple urchins likely survivors in the harsh future of an acidified ocean—and good candidates for understanding how marine creatures may adapt to rapidly changing conditions.

It is well understood that rising average global temperatures are a fundamental driver of the imminent extinction faced by a million or more species—as a recent UN biodiversity report notes. But it’s not just rising averages that matter. It may be the hottest—or most acidic—moments that test an organism’s limits and control its survival. And, as the UVM team writes, “the genetic mechanisms that allow rapid adaptation to extreme conditions have been rarely explored.”

Currency in the current sea

The new study used an innovative “single-generation selection” experiment that began with twenty-five wild-caught adult urchins. Each female produced about 200,000 eggs from which the scientists were able to extract DNA out of pools of about 20,000 surviving larvae that were living in differing water conditions. This very large number of individuals gave the scientists a clear view that purple urchins possess a genetic heritage that lets them adapt to extremely acidic ocean water. “This species of sea urchin is going to be okay in the short term. They can respond to these low pH conditions and have the needed genetic variation to evolve,” says UVM’s Reid Brennan. “So long as we do our part to protect their habitats and keep their populations large.”

But coming through the ferocious challenge of rapid climate change may come at a high cost. “It’s hopeful that evolution happens—and it’s surprising and exciting that these rare variants play such a powerful role,” says Melissa Pespeni, an assistant professor in UVM’s biology department and expert on ocean ecosystems. “This discovery has important implications for long-term species persistence. These rare variants are a kind of currency that urchins have to spend,” she says. “But they can only spend it once.”

University of Vermont Extension will expand a program proven to reduce risky behavior in youth, including substance misuse, called PROSPER to schools in St. Johnsbury, Newport and Derby. The program is currently in place at three Vermont schools.

PROSPER, for Promoting School-Community-University Partnerships to Enhance Resilience, was developed jointly at Iowa State University and Pennsylvania State University in 2001 and has been implemented in communities around the country since then. Its effectiveness has been demonstrated in nearly 80 published research studies.

The two-year program targets sixth and seventh graders.

“We’re honored and pleased to be able to expand the PROSPER program to three communities in the Northeast Kingdom,” said Chuck Ross, director of UVM Extension. “The program has generated impressive results nationally and in the three Vermont schools where it’s in place. We have every reason to expect similar success in St. Johnsbury, Newport and Derby.”

The PROSPER expansion to St. Johnsbury and Newport will be funded with a $599,124 Children, Youth and Families at Risk (CYFAR) grant from the National Institute of Food and Agriculture (NIFA) within USDA. Funding for the Derby expansion is coming from Iowa State. 

The program will be implemented at St. Johnsbury School in St. Johnsbury, Newport City Elementary School in Newport, and Derby Elementary School and North Country Union Junior High School in Derby, which serves both Newport and Derby.  

The PROSPER programs in St. Johnsbury and Newport will launch July 1, with Derby following three months later. UVM Extension expects that the programs in all three communities will be up and running in early 2020. 

The PROSPER Model

The PROSPER program builds competency and confidence in sixth and seventh graders and improves family functioning as bedrock strategies for preventing behavior problems in youth. 

In sixth grade, PROSPER engages families in an after-school program called Strengthening Families Program: For Parents and Youth Ages 10-14. The program shifts to an in-school focus during seventh grade with delivery of Lifeskills programming. During both years, teachers and counselors in the school deliver a set curriculum that research has shown to be effective.

Critical to the program’s success is the work of a team of eight to ten community members, including parents, teachers and other school personnel, Department of Health representatives and community members. The community team helps fine-tune the messaging of the program to the specific needs of the school, does fundraising to ensure the program is sustainable after the five-year grant expires, conducts outreach to the community about PROSPER and oversees the program’s implementation via monthly meetings.

The new PROSPER programs will be enhanced by a partnership with 4-H that will engage students in variety of leadership training programs.

Strong research results

According to research conducted by Iowa State and published in  the journal Preventive Medicine in 2013, teens involved with PROSPER program had significantly reduced rates of drug and alcohol use compared with teens not in the program.  Teens and young adults who had been through the program also had better relationships with parents, improved life skills and fewer problem behaviors in general.

According to a different study conducted by Penn State, students who participated in PROSPER had reduced initiation rates for marijuana and meth. If the findings were to generalize, about 61 students in a PROSPER community would try marijuana, as compared to 100 students in a non-PROSPER community.

The PROSPER program also has a continuing effect. One study showed it reduced alcohol use by an average of 32 percent for 10^th grade students who had participated in the program compared with peer who hadn’t. 

The principal investigator on the grant is UVM Extension’s Sarah Kleinman, the state director of 4-H. Other members of the UVM Extension team are Ellen Rowe, community and leadership development specialist and co-principal investigator/evaluator; Anthony Willey, 4-H educator and PROSPER team leader; and Kara Bissonnette, technology coordinator.Through an earlier CYFAR grant awarded to UVM Extension in 2017, PROSPER programs are in place at Lyndon Town School in Lyndonville and Otter Valley Union High School, where the program is delivered to sixth and seventh graders from five rural middle schools in the Rutland Northeast Supervisory Union. The program, with a different funding source, has been in place at Camel’s Hump Middle School in Richmond since 2013.
