Worldwide decline of coral reefs is focus of Corvallis Science Pub May 9

CORVALLIS, Ore. Research on the worldwide decline in coral reefs will take center stage at the Corvallis Science Pub on Monday, May 9.

Rebecca Vega-Thurber investigates the microbial ecology of reefs in the Red Sea, the Caribbean and the Pacific and will describe what she has learned about how microbes influence reef health.

Coral species differ in their susceptibility to bleaching and disease, but these differences are only partially explained by the evolutionary history of corals,” said Vega-Thurber, an assistant professor of microbiology at Oregon State University.

The Science Pub is free and open to the public. It begins at 6 p.m. at the Old World Deli, 341 S.W. Second St. in Corvallis.

Better understanding of the coral microbiome, Vega-Thurber added, could lead to new methods for conserving reefs.

In addition to her presentation, the Science Pub will offer a preview of scenes from Saving Atlantis,” a new movie about the worldwide Coral Microbiome Project.

Sponsors of Science Pub include Terra magazine at OSU, the Downtown Corvallis Association and the Oregon Museum of Science and Industry.

Hydropeaking of river water levels is disrupting insect survival, river ecosystems

CORVALLIS, Ore. – A group of researchers concluded today in a study in the journal BioScience that “hydropeaking” of water flows on many rivers in the West has a devastating impact on aquatic insect abundance.

The research was based in part on a huge citizen science project with more than 2,500 samples taken on the Colorado River in the Grand Canyon, and collaboration of researchers from the U.S. Geological Survey, Oregon State University, Utah State University and Idaho State University. 

It raises serious questions about the current practice of raising river volumes up and down every day – known as hydropeaking – to meet hour-by-hour electricity demand, which has nearly wiped out local populations of some insects that feed local river ecosystems.

“Insects have evolved to live with occasional extreme floods and droughts, and gradual or seasonal changes in river levels,” said David Lytle, a professor of integrative biology in the OSU College of Science. 

“These large daily rises and peaks in river flows due to hydropower dams are not normal. Prior to the construction of dams, there were almost no major daily changes in river levels. This can interrupt the egg-laying practices of some species, and the impact of this is poorly appreciated. Until now no one really looked at this, and it’s a serious problem.”

Hydropeaking is used around the world and is particularly common with hydropower dams in the American West. Rivers are some of the most extensively altered ecosystems on Earth, the researchers wrote in their study, and more than 800,000 dams exist globally. Hydropower provides 19 percent of the world’s electricity supply and far exceeds the generation of all other renewable sources combined. 

Lytle is a national expert on how organisms and communities are shaped by disturbances such as floods, droughts, and dams, with much of his research focused on aquatic insects. Hydropower dams, in this case, have a particular impact on insects that lay their eggs near the shore of streams, such as a mayfly, stonefly or caddis fly. Given normal water conditions, the eggs are laid slightly below the water surface and soon hatch. But if the water level drops suddenly, they can be stranded, dry out and die before hatching.

In this study, the researchers found a clear correlation between hydropeaking and the number of insect species present, and an almost complete absence of certain insects in some parts of rivers where they should have been present – including the Colorado River downstream of Glen Canyon and Hoover Dams. A majority of aquatic insects are vulnerable to this phenomenon, the scientists said in their report, and they can be “subject to acute mortality.” 

Some of these insects, Lytle said, are the food base for fish, birds, bats, and other wildlife.

“The loss of these aquatic insects can have a major impact on fisheries and other aspects of ecosystem health,” Lytle said. 

The researchers did point out in their study that one possible way to address the problem might be to leave river levels stable for several days at a time – possibly on weekends when electricity demands did not vary as much – so that insects could lay their eggs with success. This might help address but not totally solve the problem, Lytle said.

It’s been known that dams can impose serious environmental problems, including alterations of flow, temperature, sediment regimes and migratory fish barriers. However, the researchers called the impact of dams on aquatic insects a “hitherto unrecognized life history bottleneck.”

“For the first time, this study determines the ecological impacts of hydropeaking separated from other dam-imposed stressors, and identifies the specific cause-and-effect relationships responsible for biodiversity loss below hydroelectric dams,” said Ted Kennedy, a USGS scientist and lead author of the study. “These results may help resource managers improve river health while still meeting societal needs for renewable hydroelectricity.”

Funding for this study was provided by the Bureau of Reclamation’s Glen Canyon Dam Adaptive Management Program, the U.S. Geological Survey’s Southwest Biological Science Center, and the Department of Energy’s Western Area Power Administration.

Coal-tar based sealcoats on driveways, parking lots far more toxic than suspected

CORVALLIS, Ore. – The pavement sealcoat products used widely around the nation on thousands of asphalt driveways and parking lots are significantly more toxic and mutagenic than previously suspected, according to a new paper published this week by researchers from Oregon State University.

Of particular concern are the sealcoat products based on use of coal tar emulsions, experts say. Studies done with zebrafish – an animal model that closely resembles human reaction to toxic chemicals – showed developmental toxicity to embryos. 

Sealcoats are products often sprayed or brushed on asphalt pavements to improve their appearance and extend their lifespan. Products based on coal tar are most commonly used east of the U.S. continental divide, and those based on asphalt most common west of the divide.

The primary concern in sealcoats are polycyclic aromatic hydrocarbons, or PAHs, which are common products of any type of combustion, and have been shown to be toxic to birds, fish, amphibians, plants and mammals, including humans. 

There are many different types of PAHs. This study was able to examine the presence and biologic activity of a much greater number of them in sealcoats than has been done in any previous research. The OSU program studying PAHs is one of the most advanced of its type in the world, and can identify and analyze more than 150 types of PAH compounds.

It found some PAHs in coal tar sealcoats that were 30 times more toxic than one of the most common PAH compounds that was studied previously in these products by the U.S. Geological Survey. 

The OSU study also showed that new PAH compounds found in coal tar sealcoats had a carcinogenic risk that was 4 percent to 40 percent higher than any study had previously showed. Among the worst offenders were a group of 11 “high molecular weight” PAH derivative compounds, of which no analysis had previously been reported.

By contrast, the study showed that sealcoats based on asphalt, more commonly used in the West, were still toxic, but far less than those based on coal tar. Use of coal tar sealcoats, which are a byproduct of the coal coking process, is most common in the Midwest and East. 

The research was reported this week in Environmental Science and Technology Letters, in work supported by the National Institute of Environmental Health Science’s Superfund Research Program, and done by researchers in the OSU College of Agricultural Sciences and OSU College of Science.

“Our study is consistent with previous findings made by the USGS,” said Staci Simonich, a professor with appointments in OSU’s departments of Environmental and Molecular Toxicology and Chemistry. “But we were able to study a much wider number of PAH compounds than they did. As a result, we found even higher levels of toxicity in coal-tar based sealcoats than has previously been suspected.” 

“This should assist individuals and municipalities to make more informed decisions about the use of sealcoats and weigh their potential health risks against the benefits of these products,” said Simonich, the corresponding author on the study. “And if a decision is made to use sealcoats, we concluded that the products based on asphalt are significantly less toxic than those based on coal tar.”

The previous research done by the USGS about the potential health risks of sealcoat products has been controversial, with some industry groups arguing that the federal government agency overstated the risks. The new OSU study indicates that previous research has, if anything, understated the risks. 

A 2011 report from the USGS outlined how PAH compounds from sealcoat products can find their way into soils, storm waters, ponds, streams, lakes, and even house dust, as the compounds are tracked by foot, abraded by car tires, washed by rain and volatilize into the air. They reported that the house dust in residences adjacent to pavement that had been treated with a coal tar-based sealcoat had PAH concentrations 25 times higher than those normally found in house dust.

Some states and many municipalities around the nation have already banned the use of coal tar-based sealcoats, due to the human, wildlife and environmental health concerns. In the European Union, use of coal tar-based sealcoats is limited or banned.

Lubchenco receives Linus Pauling Legacy Award

CORVALLIS, Ore. -  Jane Lubchenco, an internationally recognized marine ecologist at Oregon State University, has received the 2016 Linus Pauling Legacy Award sponsored by the Oregon State University Libraries and Press.

The Pauling Award recognizes outstanding achievement in a subject of interest to the famous scientist and two-time Nobel laureate. Lubchenco is the ninth winner of the prestigious award, and several of the previous recipients were Nobel Prize winners.

As part of the celebration marking the award, Lubchenco will deliver a free public lecture in Portland, Ore., on Tuesday, April 26, at 7:30 p.m. at the Oregon Historical Society, 1200 S.W. Park Ave. Her presentation is titled “Scientists Making Waves and Bringing Hope.”

Lubchenco is the university distinguished professor and advisor in marine studies at OSU, and was formerly the administrator of the U.S. National Oceanic and Atmospheric Administration and under secretary of commerce for oceans and atmosphere. As one of the most highly cited ecologists in the world, she has received numerous honors including a MacArthur “genius” award and 20 honorary doctorates.

In addition to her work at OSU, Lubchenco is currently serving as the first U.S. Science Envoy for the Ocean and is an international expert on marine ecology, environmental science and climate change. She is a pioneer in the development of marine protected areas and reserves, and in fisheries reform, which are complementary efforts to return fisheries to sustainability and profitability while protecting habitats and biodiversity.

“Your accomplishments and leadership in ecology and environmental sustainability are impressive,” said Faye A. Chadwell, the Donald and Delpha Campbell university librarian and OSU press director who announced Lubchenco as the recipient of the award.

“Linus Pauling would have applauded your focus on the interactions between the environment and human well-being, as much of the work that he undertook during his long and varied career was dedicated to improving the human condition.”

Pauling, the most distinguished graduate in OSU history, is the only recipient of two unshared Nobel Prizes, for chemistry and peace. The papers of Pauling and his wife, Ava Helen Pauling, are held by OSU Libraries Special Collections and Archives Research Center, and the Linus Pauling Institute at OSU continues to pursue Pauling’s interest in the study of micronutrients and phytochemicals in diet and optimum health.

Lubchenco’s lecture in Portland is wheelchair accessible. Individuals requiring other accommodations should contact Don Frier at 541-737-4633 or don.frier@oregonstate.edu by April 20 so that appropriate arrangements can be made.

Salmon disease lab celebrates 25th anniversary

CORVALLIS, Ore. - The John L. Fryer Salmon Disease Lab at Oregon State University will commemorate its 25th anniversary on Friday, Oct. 2, offering tours of the facility and information about its contributions to our understanding of fish disease and aquatic health.

The event will be from 3-7 p.m. at 34347 N.E. Electric Road near the Trysting Tree Golf Club. It is free and open to the public, and will include a short program, special announcement, barbecue and refreshments, and live music from Wild Hog in the Woods.

The lab is named for John Fryer who started the fish disease research program at OSU.

“This facility is one of only several of its kind in the country, and provides OSU researchers a unique opportunity to study the factors affecting the health of salmon and other aquatic animals,” said Jerri Bartholomew, director of the center and head of the OSU Department of Microbiology.

For the past 25 years, research scientists at the laboratory have made important strides to manage fish diseases in the region and worldwide. These include research on vaccines, treatments for serious bacterial and viral pathogens, a screening system to help eliminate bacterial kidney disease in hatcheries, and outlining the life cycles of two major parasite infections that plague Pacific Northwest fisheries.

Recent upgrades to the lab have expanded its capabilities, making it more relevant to studying disease interactions under a range of environmental conditions. They also allow studies on warmwater aquatic species, as well as on ecological and climate change questions.

This off-campus laboratory is supported by the Department of Microbiology, in the Colleges of Science and Agricultural Sciences. People interested in attending can call 541-737-0743 or email sdl.manager@oregonstate.edu

Oregon State research reaches record, exceeds $308 million

CORVALLIS, Ore. — Oregon State University research funding reached $308.9 million, its highest level ever, in the fiscal year that ended on June 30. A near doubling of revenues from licensing patented technologies and an 8.5 percent increase in competitive federal funding fueled OSU research on a range of projects including advanced ocean-going research vessels, the health impacts of pollution and sustainable materials for high-speed computing.

“This is a phenomenal achievement. I've seen how OSU research is solving global problems and providing innovations that mean economic growth for Oregon and the nation,” said Cynthia Sagers, OSU’s vice president for research who undertook her duties on August 31. “OSU’s research performance in the last year is amazing, given that federal funds are so restricted right now.”

The overall economic and societal impact of OSU’s research enterprise exceeds $670 million, based on an analysis of OSU’s research contributions to the state and global economy that followed a recent economic study of OSU’s fiscal impact conducted by ECONorthwest.

Technology licensing almost doubled in the last year alone, from just under $6 million in 2014 to more than $10 million this year. Leading investments from business and industry were patented Oregon State innovations in agriculture, advanced materials and nuclear technologies.

OSU researchers exceeded the previous record of $288 million, which the university achieved in 2010. Although federal agencies provided the bulk of funding, most of the growth in OSU research revenues over the past five years stems from nonprofit organizations and industry.

Since 2010, total private-sector funding from sponsored contracts, research cooperatives and other sources has risen 60 percent — from $25 million to more than $40 million in 2015. Oregon State conducts research with multinationals such as HP, Nike and Boeing as well as with local firms such as Benchmade Knife of Oregon City, Sheldon Manufacturing of Cornelius and NuScale Power of Corvallis.

By contrast, federal research grants in 2015 were only 0.2 percent higher than those received in 2010, a year in which American Reinvestment and Recovery Act funds gave university research a one-time shot in the arm across the country. According to the National Science Foundation, federal agency obligations for research have dropped from a high of $36 billion in 2009 to $29 billion in 2013, the last year for which cumulative figures are available. The Department of Health and Human Services accounted for more than half of that spending.

“We’ve worked hard to diversify our research portfolio,” said Ron Adams, who retired as interim vice president for research at the end of August. “But it’s remarkable that our researchers have succeeded in competing for an increase in federal funding. This speaks to the success of our strategic initiatives and our focus on clusters of excellence.”

Economic impact stems in part from new businesses launched this year through the Oregon State University Advantage program. Among them are:

  •  OnBoard Dynamics, a Bend company designing a natural-gas powered vehicle engine that can be fueled from home
  •  Valliscor, a Corvallis company that manufactures ultra-pure chemicals
  • eChemion, a Corvallis company that develops and markets technology to extend battery life

Altogether, 15 new companies have received mentoring assistance from Oregon State’s Advantage Accelerator program, part of the state-funded Regional Accelerator and Innovation Network, or RAIN. Six new companies are working with the Advantage program this fall.

Additional economic impact stems from the employment of students, post-doctoral researchers and faculty. According to the OSU Research Office, about a quarter of OSU undergraduates participate in research projects, many with stipends paid by grant funds. In addition, grants support a total of 843 graduate research positions and 165 post-doctoral researchers.

The College of Agricultural Sciences received the largest share of research grants at Oregon State with $49.4 million last year, followed by the College of Earth, Ocean, and Atmospheric Sciences at $39 million and the College of Engineering at $37 million. The College of Science saw a 170 percent increase in research funding to $26.7 million, its largest total ever and the biggest rise among OSU colleges. Among the largest grants received in FY15 were:

  •  $8 million from the NSF to the Center for Sustainable Materials Chemistry (College of Science) for new high-speed information technologies
  •  $4 million from the Department of Energy to reduce barriers to the deployment of ocean energy systems (College of Engineering)
  •  $4 million from US Agency for International Development to the AquaFish Innovation Lab (College of Agricultural Sciences) for global food security
  •  $3.5 million from the USDA for experiential learning to reduce obesity (College of Public Health and Human Sciences)
  •  $2.3 million from the NSF for the ocean observing initiative (College of Earth, Ocean, and Atmospheric Sciences)
  •  $1.5 million from the U.S. Department of Education for school readiness in early childhood (OSU Cascades)

Debut of new pale ale to assist research on sea star wasting disease

NEWPORT, Ore. – Oregon State University and the Partnership for Interdisciplinary Studies of Coastal Oceans, or PISCO, have a new ally in their efforts to study and address sea star wasting disease, a serious epidemic that has hit the North American West Coast.

This partner is reported to be light and crisp, with a red or purplish hue and a unique flavor that comes from the purple corn nectar used to brew it. It’s sold in a tall, 22-ounce bottle, and best served cold.

As part of a larger effort to learn more about the deadly disease that has devastated sea stars in some places on the Oregon coast, a craft brewery in Newport, Ore., has announced the sale of Wasted Sea Star Purple Pale Ale. Rogue Ales and Spirits today will hold a celebration that includes a beer christening and discussion about this disease outbreak.

The Rogue Ale brewers, who are concerned about this disease in Oregon coastal waters, plan to donate a portion of the income from sales of this product to support research done by OSU and PISCO scientists.  More information on Rogue Ales and Spirits’ new ale is available online at www.rogue.com/roguenews

“We are extremely excited about this new partnership with Rogue to raise awareness about the importance of sea stars to healthy ocean ecosystems,” said Bruce Menge, the lead PISCO-OSU investigator. “Rogue’s new beer also recognizes the efforts of investigators across the country who are collaborating to understand this disease and its impacts.”

Kristen Milligan, PISCO program coordinator, said, “This is an excellent example of an industry-academia partnership that can help educate, at the same time as helping to support the necessary science.”

Last year there was an unprecedented outbreak of sea star wasting disease on the Oregon coast, causing sea stars to lose arms, disintegrate and die over the course of a week or less. Today in Oregon, adult ochre star populations in the rocky intertidal zone are down dramatically from a year ago - anywhere from 30-80 percent less, depending on the location.

Researchers are carefully monitoring the survival of young sea stars, which are appearing at most locations along the coast in great numbers and offer some hope for population recovery.

Sea stars are an important part of marine ecosystems, in part because they attack mussels and keep their populations under control. Without enough sea stars, mussel populations can expand and grow over algae and other small invertebrates. The very concept of a “keystone predator” came from work in 1969 that used the purple ochre sea star as a model.

OSU researchers and students are working both to monitor and address this problem, in collaboration with a number of Oregon public and private agencies, and their PISCO partners at the University of California/Santa Cruz, UC/Santa Barbara, and Stanford University.

The art and science of color to be topic at Corvallis Science Pub

CORVALLIS, Ore. – From art to clothes to entertainment, color shapes modern life. At the Corvallis Science Pub on Monday, April 6, Oregon State University chemist Mas Subramanian will present the art and science of color as it has affected culture and even generated economic opportunity.

Subramanian’s lab discovered a brilliant blue pigment in 2009 and has continued to develop applications with artists, paint manufacturers and other companies. In addition to blue, his lab has developed purples, greens and oranges with durable, environmentally beneficial qualities.

Subramanian will describe the chemical and physical origins of color in pigments and light. He’ll span the uses of colors in nature such as geology (gems and metals), biology (butterflies, peacock, hummingbirds, flamingos, eyes) and botany (plants, flowers, berries), and explain the origin of color in pigments used in art and industry.

The Science Pub presentation is free and open to the public. It begins at 6 p.m. at the Old World Deli, 341 S.W. 2nd St. in Corvallis. Sponsors of Science Pub include Terra magazine at OSU, the Downtown Corvallis Association and the Oregon Museum of Science and Industry.
