CORVALLIS, Ore - Bill Braunworth has been selected to head the Department of Horticulture at Oregon State University, following a national search.
Since 1992, Braunworth has served OSU as the program leader of the Agricultural Sciences and Natural Resources Extension Program. As program leader, he developed greater budget capacity and flexibility and worked to preserve the Extension horticulture program in Multnomah, Lane, Linn and Lincoln counties.
In 2001, he led a 30-member team of scientists from three universities that reported the impacts from reallocation of water in the Klamath Basin.
Braunworth, who earned a doctorate in horticulture from OSU in 1986, has worked as an agronomist on water use and management in Egypt and as a horticultural researcher in Malawi.
He served as the interim department head in horticulture after Anita Azarenko left the department in 2012 to become associate dean of OSU’s graduate school.College of Agricultural Sciences Media Contact: Peg Herring Source:

CORVALLIS, Ore. – Oregon State University scientists have discovered how to pinpoint the time and place of underwater volcanic eruptions using satellite images.
Volcanic eruptions on the ocean floor can spew large amounts of pumice and fine particles, as well as hot water that brings nutrients to the surface, resulting in plumes of algae. The plumes are picked up as shades of green in satellite images.
"Some volcanic eruptions take place hundreds of feet below water and show no changes to the sea surface to the naked eye," said Robert O'Malley, an OSU research assistant in botany and plant pathology in OSU's College of Agricultural Sciences. “It's amazing an orbiting satellite can detect color changes that indicate an eruption has taken place. Many times you can't spot an eruption if you were floating over it in a boat.”
Underwater volcanic eruptions are rarely detected, so little is known about them, according to Mike Behrenfeld, an OSU expert in marine algae and and one of the researchers on the project.
"Satellite measurements of the planet are made every day,” Behrenfeld said, “so this new method provides another tool for spotting these dramatic events that affect life in the oceans."
O'Malley and Behrenfeld developed a process for analyzing low-resolution images to show evidence of eruptions, which can extend over thousands of square miles, by matching five known eruptions with data from NASA satellites.
"We measured sunlight going into the ocean interacting with particles consistent with underwater volcanic eruptions," said O'Malley. “From there, we found we could connect color data with documented eruptions. Now we have a better idea of what to look for in the data when we don't know about the eruption first."
Next, the researchers plan to test how well their method works as eruptions are happening. Further study will also focus on the depth at which eruptions can be detected.
The research was funded by NASA's Ocean Biology and Geochemistry Program.

An online program at OSU is helping to address a national shortage of computer science graduates, while opening new careers to anyone who already has a bachelor's degree.
CORVALLIS, Ore. – An online computer science degree program at Oregon State University – the only one of its type in the nation designed specifically for post-baccalaureate students – has grown rapidly, helping to address a national shortage of computer science graduates.
Although it was launched only 18 months ago by the School of Electrical Engineering and Computer Science, by the end of this year the program will allow the school to double the number of its computer science graduates with a bachelor’s degree.
Developed in collaboration with OSU’s highly ranked Ecampus, the program allows students with a bachelor’s degree in another field to complete a degree in as little as 12 months because no general education courses are required. Many students choose a slower pace, however, and the courses are geared to people with no computer science experience.
The program has attracted students with a broad range of previous degrees including accounting, chemistry, engineering, history, journalism, law, psychology, and political science; 39 percent of the students come with backgrounds in humanities and social sciences. The online format allows individuals juggling work and family an easier way to go back to school.
According to a recent survey by the Technology Councils of North America, the entire nation is experiencing a shortage of people trained in computer science. Two-thirds of technology company executives in North America agreed there is a talent shortage, and the crisis is particularly acute in Oregon where 86 percent of executives reported there is a shortage of talent in a survey conducted by the Technology Association of Oregon.
A key strategy in the 2014 Oregon Business Plan is to better connect education with high-paying jobs in science and technology fields, including computer science.
Although the 755 students admitted to the online program are from all over the world, more than half of them are from Oregon, Washington and California, and 23 percent now live in Oregon.
“OSU’s one-year online degree program in computer science is working to help fill some of the gaps by offering students and professionals a flexible way to obtain valuable skills and increase their marketability within the local tech industry,” said Skip Newberry, president of the Technology Association of Oregon.
It’s also making a personal impact on individuals. With an established career in business and two small children, Bental Wong said he would not have been able to return to school to carry out his dream of becoming a software engineer, if it had not been for the flexibility of this program. After completing the program in a year, Wong immediately had three job offers and is now part of a small team at Hewlett Packard in Vancouver, Wash., creating innovative software for HP printers.
“It’s so rewarding to hear about the successes of our students,” said Terri Fiez, head of the School of Electrical Engineering and Computer Science. “We are proud of the impact this program is having on the lives of our students and the tech industry.”College of Engineering Media Contact:

New research suggests many college students may experience "food insecurity," with possible impacts on their health and academic performance.
The study this story is based on is available in ScholarsArchive@OSU: http://bit.ly/LCp10Y
CORVALLIS, Ore. – One of the few studies of its type has found that a startling 59 percent of college students at one Oregon university were “food insecure” at some point during the previous year, with possible implications for academic success, physical and emotional health and other issues.
Contrary to concerns about obesity and some students packing on “the freshman 15” in weight gain, another reality is that many students are not getting enough healthy food to eat as they struggle with high costs, limited income, and fewer food or social support systems than are available to other groups.
The findings were published recently in the Journal of Nutrition Education and Behavior, by researchers from Oregon State University, the Benton County Health Department, and Western Oregon University. Students at Western Oregon were surveyed as the basis for the study.
“Based on other research that’s been done, we expected some amount of food concerns among college students,” said Daniel López-Cevallos, associate director of research at OSU’s Center for Latino/a Studies and Engagement. “But it was shocking to find food insecurity of this severity. Several recent trends may be combining to cause this.”
The researchers said a combination of rising college costs, more low-income and first-generation students attending college, and changing demographic trends are making this issue more significant than it may have been in the past.
“For past generations, students living on a lean budget might have just considered it part of the college experience, a transitory thing,” said Megan Patton-López, lead author of the study with Oregon’s Benton County Health Department.
“But rising costs of education are now affecting more people,” she said. “And for many of these students who are coming from low-income families and attending college for the first time, this may be a continuation of food insecurity they’ve known before. It becomes a way of life, and they don’t have as many resources to help them out.”
Most college students, with some exceptions, are not eligible for food stamps and many are often already carrying heavy debt loads. And the study found that even though many of them work one or more jobs, the financial demands are such that they still may not have enough money for healthy food at all times.
Food insecurity is defined as limited or uncertain availability of nutritionally adequate and safe foods, and the ability to acquire such food in acceptable ways. It has been associated with depression, stress, trouble learning in the classroom, and poor health. When similar issues have been addressed with elementary school students, improvements were seen in academic performance, behavior and retention of knowledge.
But these problems have received scarcely any attention in the 19-24 year old, young-adult demographic that predominates in college, the scientists said.
Among the findings of this study:
- While about 14.9 percent of all households in the nation report food insecurity, the number of college students voicing similar concerns in this report was almost four times higher, at 59 percent.
- In the past three decades the cost of higher education has steadily outpaced inflation, the cost of living and medical expenses.
- Food insecurity during college years could affect cognitive, academic and psychosocial development.
- Factors correlated with reports of food insecurity include fair to poor health, a lower grade point average, low income and employment.
Employment, by itself, is not adequate to resolve this problem, the researchers found. Students reporting food insecurity also worked an average of 18 hours a week – some as high as 42 – but the financial demands they faced more than offset that income.
These findings were based on a survey of 354 students at Western Oregon University, a mid-size public university in a small town near the state capitol in Salem, Ore. Students at Western Oregon supported and assisted in this research, and Doris Cancel-Tirado and Leticia Vazquez with Western Oregon co-authored the study.
The findings probably reflect similar concerns at colleges and universities across the nation, the researchers said, although more research is needed in many areas to determine the full scope of this problem.
“One thing that’s clear is that colleges and universities need to be having this conversation and learning more about the issues their students may be facing,” said López-Cevallos. “There may be steps to take locally that could help, and policies that could be considered nationally. But it does appear this is a very serious issue that has not received adequate attention, and we need to explore it further.”College of Liberal Arts Media Contact: David Stauth Source:

Omega-3 fatty acids, particularly DHA, may have an even wider range of benefits that previously considered, new research suggests.
The study this story is based on is available online: http://bit.ly/1dDuf7i
CORVALLIS, Ore. – A study of the metabolic effects of omega-3 fatty acids, especially DHA, concludes that these compounds may have an even wider range of biological impacts than previously considered, and suggests they could be of significant value in the prevention of fatty liver disease.
The research, done by scientists at Oregon State University and several other institutions, was one of the first of its type to use “metabolomics,” an analysis of metabolites that reflect the many biological effects of omega-3 fatty acids on the liver. It also explored the challenges this organ faces from the “Western diet” that increasingly is linked to liver inflammation, fibrosis, cirrhosis and sometimes liver failure.
The results were surprising, researchers say.
Supplements of DHA, used at levels that are sometimes prescribed to reduce blood triglycerides, appeared to have many unanticipated effects. There were observable changes in vitamin and carbohydrate metabolism, protein and amino acid function, as well as lipid metabolism.
Supplementation with DHA partially or totally prevented metabolic damage through those pathways often linked to the Western diet – excessive consumption of red meat, sugar, saturated fat and processed grains.
The findings were published last month in PLOS One, an online professional journal.
“We were shocked to find so many biological pathways being affected by omega-3 fatty acids,” said Donald Jump, a professor in the OSU College of Public Health and Human Sciences. “Most studies on these nutrients find effects on lipid metabolism and inflammation.
“Our metabolomics analysis indicates that the effects of omega-3 fatty acids extend beyond that, and include carbohydrate, amino acid and vitamin metabolism,” he added.
Omega-3 fatty acids have been the subject of much recent research, often with conflicting results and claims. Possible reasons for contradictory findings, OSU researchers say, are the amount of supplements used and the relative abundance of two common omega-3s – DHA and EPA. Studies at OSU have concluded that DHA has far more ability than EPA to prevent the formation of harmful metabolites. In one study, it was found that DHA supplementation reduced the proteins involved in liver fibrosis by more than 65 percent.
These research efforts, done with laboratory animals, used a level of DHA supplementation that would equate to about 2-4 grams per day for an average person. In the diet, the most common source of DHA is fatty fish, such as salmon, mackerel or sardines.
The most recent research is beginning to break down the specific processes by which these metabolic changes take place. If anything, the results suggest that DHA may have even more health value than previously thought.
“A lot of work has been done on fatty liver disease, and we are just beginning to explore the potential for DHA in preventing or slowing disease progression,” said Jump, who is also a principal investigator in OSU’s Linus Pauling Institute.
“Fish oils, a common supplement used to provide omega-3, are also not prescribed to regulate blood glucose levels in diabetic patients,” he said. “But our studies suggest that DHA may reduce the formation of harmful glucose metabolites linked to diabetic complications.”
Both diabetes and liver disease are increasing steadily in the United States.
The American Liver Foundation has estimated that about 25 percent of the nation’s population, and 75 percent of those who are obese, have nonalcoholic fatty liver disease. This can progress to nonalcoholic steatohepatitis, cirrhosis and cancer.
This study established that the main target of DHA in the liver is the control of inflammation, oxidative stress and fibrosis, which are the characteristics of more progressively serious liver problems. Omega-3 fatty acids appear to keep cells from responding to and being damaged by whatever is causing inflammation.
Collaborators on this research were from OSU, the Baylor College of Medicine, Vanderbilt University Medical Center, and Metabolon, Inc. It was supported by the USDA and the National Institutes of Health.College of Public Health and Human Sciences Media Contact: David Stauth Source:

Manual removal of invasive lionfish from some reefs shows promise in allowing the comeback of native fish populations in the Atlantic Ocean.
The study this story is based on is available online: http://bit.ly/1f9fqbg
CORVALLIS, Ore. – It may take a legion of scuba divers armed with nets and spears, but a new study confirms for the first time that controlling lionfish populations in the western Atlantic Ocean can pave the way for a recovery of native fish.
Even if it’s one speared fish at a time, it finally appears that there’s a way to fight back.
Scientists at Oregon State University, Simon Fraser University and other institutions have shown in both computer models and 18 months of field tests on reefs that reducing lionfish numbers by specified amounts – at the sites they studied, between 75-95 percent – will allow a rapid recovery of native fish biomass in the treatment area, and to some extent may aid larger ecosystem recovery as well.
It’s some of the first good news in a struggle that has at times appeared almost hopeless, as this voracious, invasive species has wiped out 95 percent of native fish in some Atlantic locations.
“This is excellent news,” said Stephanie Green, a marine ecologist in the College of Science at Oregon State University, and lead author on the report just published in Ecological Applications. “It shows that by creating safe havens, small pockets of reef where lionfish numbers are kept low, we can help native species recover.
“And we don’t have to catch every lionfish to do it.”
That’s good, researchers say, because the rapid spread of lionfish in the Atlantic makes eradication virtually impossible. They’ve also been found thriving in deep water locations which are difficult to access.
The latest research used ecological modeling to determine what percentage of lionfish would have to be removed at a given location to allow for native fish recovery. At 24 coral reefs near Eleuthera Island in the Bahamas, researchers then removed the necessary amount of lionfish to reach this threshold, and monitored recovery of the ecosystem.
On reefs where lionfish were kept below threshold densities, native prey fish increased by 50-70 percent. It’s one of the first studies of its type to demonstrate that reduction of an invasive species below an environmentally damaging threshold, rather than outright eradication, can have comparable benefits.
Some of the fish that recovered, such as Nassau grouper and yellowtail snapper, are critically important to local economies. And larger adults can then spread throughout the reef system – although the amount of system recovery that would take place outside of treated areas is a subject that needs additional research, they said.
Where no intervention was made, native species continued to decline and disappear.
The lionfish invasion in the Atlantic, believed to have begun in the 1980s, now covers an area larger than the entirety of the United States. With venomous spines, no natural predators in the Atlantic Ocean, and aggressive behavior, the lionfish have been shown to eat almost anything smaller than they are – fish, shrimp, crabs and octopus. Lionfish can also withstand starvation for protracted periods – many of their prey species will disappear before they do.
Governments, industry and conservation groups across this region are already trying to cull lionfish from their waters, and encourage their use as a food fish. Some removal efforts have concentrated on popular dive sites.
The scientists said in their report that the model used in this research should work equally well in various types of marine habitat, including mangroves, temperate hard-bottom systems, estuaries and seagrass beds.
A major issue to be considered, however, is where to allocate future removal efforts. Marine reserves, which often allow “no take” of any marine life in an effort to recover fish populations, may need to be the focus of lionfish removal. The traditional, hands-off concept in such areas may succeed only in wiping out native species while allowing the invasive species to grow unchecked.
Keeping lionfish numbers low in areas that are hot spots for juvenile fish, like mangroves and shallow reefs, is also crucial, the report said.
This research was done in collaboration with scientists at Simon Fraser University, the Reef Environmental Education Foundation, and the Cape Eleuthera Institute. It has been supported by the Natural Science and Engineering Research Council of Canada, the Boston Foundation and a David H. Smith Conservation Research Fellowship.
“Many invasions such as lionfish are occurring at a speed and magnitude that outstrips the resources available to contain and eliminate them,” the researchers wrote in their conclusion. “Our study is the first to demonstrate that for such invasions, complete extirpation is not necessary to minimize negative ecological changes within priority habitats.”College of Science Media Contact: David Stauth Source:

A newly published study found that you don’t need to run 10 miles a day to gain health benefits – just log more minutes of light physical activity than of sedentary behavior.
CORVALLIS, Ore. – A newly published study looking at activity trends and outcomes among American adults found that you don’t need to kill yourself by running 10 miles a day to gain health benefits – you merely need to log more minutes of light physical activity than of sedentary behavior.
And the bar is pretty low for what constitutes light physical activity, researchers say. It can mean sauntering through a mall window-shopping instead of ordering online, fishing along a riverbank, or ballroom dancing.
In other words, casting a spinner or spinning on the dance floor can help offset our sedentary ways.
The problem, the authors say, is that nearly half of Americans surveyed did not engage in a sufficient amount of moderate-to-vigorous physical activity (more than 150 minutes a week) and, in fact, spent more time in sedentary mode than even doing light physical activity.
“That’s actually rather frightening,” said Bradley Cardinal, co-director of the Sport and Exercise Psychology Program at Oregon State University and co-author on the study. “About half of the people in this country are incredibly sedentary – basically, couch potatoes. And that can have some very negative effects on one’s health.”
Results of the study have been published online in the journal Preventive Medicine.
The study looked at the activity patterns of more than 5,500 adults through the National Health and Nutrition Examination Survey. Participants wore accelerometers recording movements that could be broken down by the minute, and the researchers found that 47.2 percent of Americans engaged in less than 150 minutes a week of moderate-to-vigorous physical activity and, perhaps more importantly, logged fewer minutes of light physical activity than of sedentary behavior.
They found that when the balance was on the positive side – adults spent more time moving than sitting – there was a strong association with favorable levels of triglycerides and insulin.
“It is preferable to get at least 30 minutes a day of moderate-to-vigorous physical activity in each day, but we now know that if you sit for the remainder of the day after getting this dose of exercise, you might not necessarily be escaping the risk of developing chronic disease,” said Paul Loprinzi, a former doctoral student under Cardinal in OSU’s College of Public Health and Human Sciences. Now an assistant professor at Bellarmine University, Loprinzi is lead author on the study.
“These findings demonstrate the importance of minimizing sedentary activities and replacing some of them with light-intensity activities, such as pacing back and forth when on the phone, standing at your desk periodically instead of sitting, and having walking meetings instead of sit-down meetings,” he added.
Cardinal said results can vary with individuals, based on age, fitness levels, movement “pace” and other factors. In general, however, when even light activity minutes in a day surpass sedentary minutes, it can result in improved triglyceride and insulin levels.
“Someone just ambling along on a leisurely stroll may not get the same benefits as someone moving briskly – what we call a ‘New York City walk,’” Cardinal said, “but it still is much better than lying on the couch watching TV. Even sitting in a rocking chair and rocking back-and-forth is better than lying down or just sitting passively.
“Think about all the small things you can do in a day and you’ll realize how quickly they can add up,” Cardinal pointed out.
Some of the ways Americans can get in some light physical activity without Olympic-style training:
- Go on a leisurely bicycle ride, at about 5-6 miles an hour;
- Use a Wii Fit program that requires a light effort, like yoga or balancing;
- Do some mild calisthenics or stretching;
- If you want to watch television, do it sitting on a physioball;
- Play a musical instrument;
- Work in the garden.
“Even everyday home activities like sweeping, dusting, vacuuming, doing dishes, watering the plants, or carrying out the trash have some benefits,” Cardinal said.
“Remember, it’s making sure you’re moving more than you’re sitting that’s the key.”
The study was supported by Oregon State University. Hyo Lee, a former Ph.D. student at OSU now with Sangmyung University in Korea, is also a co-author on the study.College of Public Health and Human Sciences Media Contact: Mark Floyd Source:
A new business being aided by the Oregon State Advantage Accelerator will offer users a mobile app to enhance their social shopping experience.
CORVALLIS, Ore. – A new business concept aided by the Oregon State University Advantage Accelerator will get its first test run on Tuesday, Jan. 21, when about 120 OSU sorority members get a chance to see what all their friends think about the new shoes they may buy – and which color looks best.
It’s the beginning of Tally, a mobile app developed by two recent OSU graduates to make shopping or just getting dressed a more fun, interactive and social experience.
With Tally, users can receive side-by-side images of their friend’s shopping options, vote on their favorite image and get results delivered in real time.
The developers of this company will also be interviewed on Jan. 30 at OSU by Alexis Ohanian, the co-founder of Reddit.com, one of the world’s leading web sites. Ohanian will be speaking about his new book, Without Their Permission, as part of a 77-university tour about Internet entrepreneurship, at the LaSells Stewart Center beginning at 7 p.m. It is free and open to the public.
“Our release of the app to the OSU sororities is really exciting, and we’ll be very interested in their feedback as we try to fine tune the user experience,” said Ryan Connolly, a graduate last year in marketing and entrepreneurship in the OSU College of Business, who co-founded the company with Andy Miller, an OSU computer science graduate.
“We are very optimistic about the app and anxious to see what’s in store for the future,” Connolly said. “It’s free for people to download and use, and will help make shopping a more social experience, even if your friends live in another city or on the other side of the country. People can see what their friends think before they make a decision, and in our tests about 65 percent of our current users vote on each new poll within 20 minutes.”
The OSU Advantage Accelerator, which was recently formed to help this and other small business enterprises get the assistance they need to move out of academia and into the private sector, was a great help, Connolly said.
“The Accelerator gave us two mentors to work with, helped flush out our revenue model, introduced us to investors, and gave us exposure we wouldn’t have otherwise had,” he said.
The business concept of the company is to develop a large and active user base, Connolly said, and then approach clothing retailers and brands as a pinpoint marketing platform. Information will be acquired about merchandise, style, color and product preferences that would be of value to retailers, manufacturers and brand owners.

Researchers are near a complete understanding of how humans walk, with implications for improved robotics, biomedical devices and other fields.
The study this story is based on is available online: http://bit.ly/1d1KZ3u
CORVALLIS, Ore. – Humans and some of our hominid ancestors such as Homo erectus have been walking for more than a million years, and researchers are close to figuring out how we do it.
It’s never been completely clear how human beings accomplish the routine, taken-for-granted miracle we call walking, let alone running. But findings published last month in the Journal of Experimental Biology outline a specific interaction between the ankle, knee, muscles and tendons that improve the understanding of a leg moving forward in a way that maximizes motion while using minimal amounts of energy.
The research could find some of its earliest applications in improved prosthetic limbs, said researchers in the College of Engineering at Oregon State University. Later on, a more complete grasp of these principles could lead to walking or running robots that are far more agile and energy-efficient than anything that exists today.
“Human walking is extraordinarily complex and we still don’t understand completely how it works,” said Jonathan Hurst, an OSU professor of mechanical engineering and expert in legged locomotion in robots. There’s a real efficiency to it – walking is almost like passive falling. The robots existing today don’t walk at all like humans, they lack that efficiency of motion and agility.
“When we fully learn what the human leg is doing,” Hurst added, “we’ll be able to build robots that work much better.”
Researchers have long observed some type of high-power “push off” when the leg leaves the ground, but didn’t really understand how it worked. Now they believe they do. The study concluded there are two phases to this motion. The first is an “alleviation” phase in which the trailing leg is relieved of the burden of supporting the body mass.
Then in a “launching” phase the knee buckles, allowing the rapid release of stored elastic energy in the ankle tendons, like the triggering of a catapult.
“We calculated what muscles could do and found it insufficient, by far, for generating this powerful push off,” said Daniel Renjewski, a postdoctoral research associate in the Dynamic Robotics Laboratory at OSU. “So we had to look for a power-amplifying mechanism.
“The coordination of knee and ankle is critical,” he said. “And contrary to what some other research has suggested, the catapult energy from the ankle is just being used to swing the leg, not add large amounts of energy to the forward motion.”
Walking robots don’t do this. Many of them use force to “swing” the leg forward from something resembling a hip point. It can be functional, but it’s neither energy-efficient nor agile. And for more widespread use of mobile robots, energy use is crucially important, the researchers said.
“We still have a long way to go before walking robots can move with as little energy as animals use,” Hurst said. “But this type of research will bring us closer to that.”
The research was supported by the German Research Foundation. The Dynamic Robotics Laboratory at OSU is supported by the Human Frontier Science Program, the National Science Foundation and the Defense Advanced Research Projects Agency, and has helped create some of the leading technology in the world for robots that can walk and run.
One model can run a nine-minute mile and step off a ledge, and others are even more advanced. Robots with the ability to walk and maneuver over uneven terrain could ultimately find applications in prosthetic limbs, an exo-skeleton to assist people with muscular weakness, or use in the military, disaster response or any dangerous situation.College of Engineering Media Contact: David Stauth Source:

In a finding that overturns the conventional view that large old trees are unproductive, scientists have determined that for most species, the biggest trees increase their growth rates and sequester more carbon as they age.
CORVALLIS, Ore. – In a finding that overturns the conventional view that large old trees are unproductive, scientists have determined that for most species, the biggest trees increase their growth rates and sequester more carbon as they age.
In a letter published today in the journal Nature, an international research group reports that 97 percent of 403 tropical and temperate species grow more quickly the older they get. The study was led by Nate L. Stephenson of the U.S. Geological Survey Western Ecological Research Center. Three Oregon State University researchers are co-authors: Mark Harmon and Rob Pabst of the College of Forestry and Duncan Thomas of the College of Agricultural Sciences.
The researchers reviewed records from studies on six continents. Their conclusions are based on repeated measurements of 673,046 individual trees, some going back more than 80 years.
This study would not have been possible, Harmon said, without long-term records of individual tree growth. “It was remarkable how we were able to examine this question on a global level, thanks to the sustained efforts of many programs and individuals.”
Extraordinary growth of some species, such as Australian mountain ash – also known as eucalyptus – (Eucalyptus regnans), and the coast redwood (Sequoia sempervirens), is not limited to a few species, the researchers said. “Rather, rapid growth in giant trees is the global norm and can exceed 600 kg (1,300 pounds) per year in the largest individuals,” they wrote.
“In human terms, it is as if our growth just keeps accelerating after adolescence, instead of slowing down,” said Stephenson. “By that measure, humans could weigh half a ton by middle age, and well over a ton at retirement.”
The report includes studies from the Pacific Northwest. Harmon and his colleagues worked in forest plots – some created as early as the 1930s – at the H.J. Andrews Experimental Forest east of Eugene and Mount Rainier National Park. Researchers measured growth in Douglas-fir, western hemlock, Sitka spruce, western red cedar and silver fir. The National Science Foundation and the Pacific Northwest Research Station of the USDA Forest Service provided funding.
Under the auspices of the Smithsonian Institution’s Center for Tropical Forest Science, Thomas and colleagues in Africa established a 123-acre forest research site in Cameroon in 1996. They measured growth in about 495 tree species.
“CTFS does very important work facilitating collaboration between forest ecologists worldwide and therefore enabling us to gain a better insight into the growth of trees and forests,” Thomas said. “This model for collaboration was the basis of the Nature study.”
While the finding applies to individual trees, it may not hold true for stands of trees, the authors cautioned. As they age, some trees in a stand will die, resulting in fewer individuals in a given area over time.
The study was a collaboration of 38 scientists from research universities, government agencies and non-governmental organizations in the United States, Panama, Australia, United Kingdom, Germany, Colombia, Argentina, Thailand, Cameroon, Democratic Republic of Congo, France, China, Taiwan, Malaysia, New Zealand and Spain.

Oregon State University’s First Lady, Beth Ray, will be celebrated Monday, Jan. 13, in a ceremony renaming the OSU Student Success Center in her honor.
CORVALLIS, Ore. – Oregon State University’s First Lady, Beth Ray, will be celebrated Monday, Jan. 13, in a ceremony renaming the OSU Student Success Center in her honor. It will now be called The Beth Ray Center for Academic Support.
The rededication ceremony begins with a reception at 4:30 p.m., followed by a program at 5 p.m. The center is located just south of the parking structure on 26th Street, in the center of campus.
Ray, who is currently battling advanced small cell carcinoma, an incurable cancer, is a greatly loved member of the OSU community, and the push to rename the center in her honor was largely driven by student enthusiasm. After the idea was proposed by OSU Athletic Director Bob DeCarolis, the Oregon State Student Athlete Advisory Committee unanimously supported the idea of changing the name of the center to honor Ray, and the student government organization ASOSU also supported the plan. Support for the re-naming was also provided by the university’s building naming committee and the OSU Faculty Senate and was authorized by Oregon University System Interim Chancellor Melody Rose.
Ray is seen by many students as a mentor and supporter, making the building, which is oriented toward student support, a natural extension of her interest in student success.
“The Beth Ray Center for Academic Support will serve as an essential place where all students can gather throughout the day and evenings to receive personal assistance along their path to graduation,” said Provost and Vice President Sabah Randhawa.
Ray said she was both surprised and excited about the news of the building renaming, and pleased that the honor focused on student support. A former business law professor, academic counselor and assistant dean for academic advising, Ray, 67, has been been teaching and mentoring students for many years.
“Most of my career involves working with students,” Ray said.
In her 10 years at OSU, Ray has seen many of the students she’s mentored go on to graduate and thrive. She keeps in contact with a number of them, taking the opportunity to have lunch and visit when they’re in the area. And each year a whole new crop of students arrives on campus in need of support and advice.
“I would tell freshmen to talk to their professors and advisors, and if they have a problem to share it,” she said. “Most people try to hide their problems, but you shouldn’t feel bad about asking people questions.”
Jaimee Kirkpatrick, executive assistant to Head Men’s Basketball Coach Craig Robinson, was one of the students Ray took under her wing as an OSU student. She said through many challenges and successes, the Rays were always there to support and guide her.
“Beth Ray holds an even more special place in my heart as she was one of the only female adults that took care of me as I went through some major surgeries during my time as a student at Oregon State,” Kirkpatrick said. “While my parents were living in Alaska, Beth took over and comforted, encouraged, and supported me through some very significant challenges in my life to date.”
The $14 million Student Success Center opened in 2012, and houses programs that provide both the general student population and student-athletes with a range of academic support services. Hundreds of students are served every day in the building. The facility includes classrooms, a computer lab, study lounge and commons area as well as academic counseling and advising offices, meeting rooms and tutorial spaces.Generic OSU Media Contact: Theresa Hogue Source:

A new analysis reveals that the world is developing "hotspots" of decline in several species of large carnivorous predators, with significant repercussions on ecosystem function.
CORVALLIS, Ore. – In ecosystems around the world, the decline of large predators such as lions, dingoes, wolves, otters, and bears is changing the face of landscapes from the tropics to the Arctic – but an analysis of 31 carnivore species to be published Friday in the journal Science shows for the first time how threats such as habitat loss, persecution by humans and loss of prey combine to create global hotspots of carnivore decline.
More than 75 percent of the 31 large-carnivore species are declining, and 17 species now occupy less than half of their former ranges, the authors reported.
Southeast Asia, southern and East Africa and the Amazon are among areas in which multiple large carnivore species are declining. With some exceptions, large carnivores have already been exterminated from much of the developed world, including Western Europe and the eastern United States.
“Globally, we are losing our large carnivores,” said William Ripple, lead author of the paper and a professor in the Department of Forest Ecosystems and Society at Oregon State University.
“Many of them are endangered,” he said. “Their ranges are collapsing. Many of these animals are at risk of extinction, either locally or globally. And, ironically, they are vanishing just as we are learning about their important ecological effects.”
Ripple and colleagues from the United States, Australia, Italy and Sweden called for an international initiative to conserve large predators in coexistence with people. They suggested that such an effort be modeled on the Large Carnivore Initiative for Europe, a nonprofit scientific group affiliated with the International Union for the Conservation of Nature.
The researchers reviewed published scientific reports and singled out seven species that have been studied for their widespread ecological effects or “trophic cascades.” This includes African lions, leopards, Eurasian lynx, cougars, gray wolves, sea otters and dingoes.
Ripple and his Oregon State co-author Robert Beschta have documented impacts of cougars and wolves on the regeneration of forest stands and riparian vegetation in Yellowstone and other national parks in North America. Fewer predators, they have found, lead to an increase in browsing animals such as deer and elk. More browsing disrupts vegetation, shifts birds and small mammals and changes other parts of the ecosystem in a widespread cascade of impacts.
Studies of Eurasian lynx, dingoes, lions and sea otters have found similar effects, the authors reported.
Lynx have been closely tied to the abundance of roe deer, red fox and hare. In Australia, the construction of a 3,400-mile dingo-proof fence has enabled scientists to study ecosystems with and without the animals, which are closely related to gray wolves. In some parts of Africa, the decrease of lions and leopards has coincided with a dramatic increase in olive baboons, which threaten farm crops and livestock. In the waters off southeast Alaska, a decline in sea otters through killer whale predation has led to a rise in sea urchins and loss of kelp beds.
The authors call for a deeper understanding of the impact of large carnivores on ecosystems, a view that they trace back to the work of landmark ecologist Aldo Leopold. The classic concept that predators are harmful and deplete fish and wildlife is outdated, they said. Scientists and wildlife managers need to recognize a growing body of evidence for the complex roles that carnivores play in ecosystems and for their social and economic benefits.
Leopold recognized such relationships between predators and ecosystems, Ripple said, but his observations on that point were largely ignored for decades after his death in 1948.
“Human tolerance of these species is a major issue for conservation,” Ripple said. “We say these animals have an intrinsic right to exist, but they are also providing economic and ecological services that people value.”
Among the services that have been documented in other studies are carbon sequestration, riparian restoration, biodiversity and disease control.
Where large carnivores have been restored — such as wolves in Yellowstone or Eurasian lynx in Finland — ecosystems have responded quickly, said Ripple. “I am impressed with how resilient the Yellowstone ecosystem is. It isn’t happening quickly everywhere, but in some places, ecosystem restoration has started there.”
In those cases, where loss of vegetation has led to soil erosion, for example, full restoration in the near term may not be possible, he said.
“Nature is highly interconnected,” said Ripple. “The work at Yellowstone and other places shows how one species affects another and another through different pathways. It’s humbling as a scientist to see the interconnectedness of nature.”

CORVALLIS, Ore. – Hundreds of farmers from throughout Oregon will gather in Corvallis this winter to improve their skills and get inspired for the next growing season. The 14th annual Oregon Small Farms Conference will take place Feb. 22 from 9 a.m. to 5:30 p.m. at Oregon State University.
Michael Ableman, a nationally known farmer, author and photographer, will present the keynote address. For the first time, organizers are offering a special series of workshops in Spanish for Latino farmers. In the past the conference has provided translators for particular workshops already offered in English. Also new is a workshop on profitability for small farms.
Registration costs $45 per person until Feb. 2, then increases to $65 per person from Feb. 3-14 and $100 per person on the day of the conference – if space is still available. Organizers will cap attendance at 800 people. In the past, the popular conference has surpassed 800 attendees, said Garry Stephenson, the coordinator of OSU's Small Farms Program, which organizes the event.
"I think there's a huge social aspect to the conference – for a lot of people, this is the only time of year they get to see each other, so there's a lot of interaction and networking," said Stephenson. "We also bring in speakers who challenge people to think differently and offer a variety of workshops."
This year, attendees can register for specific workshops. The conference features 24 workshops in three concurrent sessions, as well as a lunch prepared with locally produced food. Workshops include financing a farm, growing quinoa in the Northwest, selling produce to schools and hospitals, transitioning to organic agriculture and health insurance options for farmers.
The conference is geared toward farmers, agriculture professionals, food policy advocates, students and managers of farmers markets.

Novel compounds have been discovered that may be extremely mutagenic, produced by such processes as automobile combustion or grilling meat.
CORVALLIS, Ore. – Researchers at Oregon State University have discovered novel compounds produced by certain types of chemical reactions – such as those found in vehicle exhaust or grilling meat - that are hundreds of times more mutagenic than their parent compounds which are known carcinogens.
These compounds were not previously known to exist, and raise additional concerns about the health impacts of heavily-polluted urban air or dietary exposure. It’s not yet been determined in what level the compounds might be present, and no health standards now exist for them.
The findings were published in December in Environmental Science and Technology, a professional journal.
The compounds were identified in laboratory experiments that mimic the type of conditions which might be found from the combustion and exhaust in cars and trucks, or the grilling of meat over a flame.
“Some of the compounds that we’ve discovered are far more mutagenic than we previously understood, and may exist in the environment as a result of heavy air pollution from vehicles or some types of food preparation,” said Staci Simonich, a professor of chemistry and toxicology in the OSU College of Agricultural Sciences.
“We don’t know at this point what levels may be present, and will explore that in continued research,” she said.
The parent compounds involved in this research are polycyclic aromatic hydrocarbons, or PAHs, formed naturally as the result of almost any type of combustion, from a wood stove to an automobile engine, cigarette or a coal-fired power plant. Many PAHs, such as benzopyrene, are known to be carcinogenic, believed to be more of a health concern that has been appreciated in the past, and are the subject of extensive research at OSU and elsewhere around the world.
The PAHs can become even more of a problem when they chemically interact with nitrogen to become “nitrated,” or NPAHs, scientists say. The newly-discovered compounds are NPAHs that were unknown to this point.
This study found that the direct mutagenicity of the NPAHs with one nitrogen group can increase 6 to 432 times more than the parent compound. NPAHs based on two nitrogen groups can be 272 to 467 times more mutagenic. Mutagens are chemicals that can cause DNA damage in cells that in turn can cause cancer.
For technical reasons based on how the mutagenic assays are conducted, the researchers said these numbers may actually understate the increase in toxicity – it could be even higher.
These discoveries are an outgrowth of research on PAHs that was done by Simonich at the Beijing Summer Olympic Games in 2008, when extensive studies of urban air quality were conducted, in part, based on concerns about impacts on athletes and visitors to the games.
Beijing, like some other cities in Asia, has significant problems with air quality, and may be 10-50 times more polluted than some major urban areas in the U.S. with air concerns, such as the Los Angeles basin.
An agency of the World Health Organization announced last fall that it now considers outdoor air pollution, especially particulate matter, to be carcinogenic, and cause other health problems as well. PAHs are one of the types of pollutants found on particulate matter in air pollution that are of special concern.
Concerns about the heavy levels of air pollution from some Asian cities are sufficient that Simonich is doing monitoring on Oregon’s Mount Bachelor, a 9,065-foot mountain in the central Oregon Cascade Range. Researchers want to determine what levels of air pollution may be found there after traveling thousands of miles across the Pacific Ocean.
This work was supported by the National Institute of Environmental Health Sciences and the National Science Foundation. It’s also an outgrowth of the Superfund Research Program at OSU, funded by the NIEHS, that focuses efforts on PAH pollution. Researchers from the OSU College of Science, the University of California-Riverside, Texas A&M University, and Peking University collaborated on the study.Generic OSU Media Contact: David Stauth Source:
