CINTRAFOR Grad Students Take Top Honors for Conference Posters

This past fall, SEFS graduate students Clarence Smith and Cody Sifford presented posters at the 2014 American Indian Science and Engineering Society (AISES) national conference, held November 12-15 in Orlando, Fla. Both students work within the Center for International Trade in Forest Products (CINTRAFOR), and their research posters swept the top honors in the graduate student poster competition!

Smith, of the Blackfoot Nation, placed first with his poster, “Measuring Economic Value of American Cultural Designs within the Wooden Gift Market.” Sifford, of the Navajo Nation, placed second with is poster, “Developing an Impact Assessment of Local Air Quality as a Result of Biomass Burns.”

AISES works to increase the representation of American Indians and Alaskan Natives in science, technology, engineering and math studies and careers. Held annually since 1978, its national conference is a major event that draws more than 1,600 students and professionals from across the country. That’s quite a stage to earn the top two awards in the graduate student poster competition!

Great work, Clarence and Cody, and way to represent CINTRAFOR and SEFS!

Tetiaroa: Tiny Atoll, Huge Research Potential

This past summer, Professor Aaron Wirsing of the School of Environmental and Forest Sciences (SEFS) helped initiate a pilot research program to study the biology of reef sharks on a tiny atoll in the South Pacific. Tetiaroa, located about 33 miles north of Tahiti in French Polynesia, is comprised of a ring of 12 coral islets—also known as motus—surrounding a shallow lagoon. Largely untouched by human development, the lagoon is home to several shark nurseries, or areas where shark pups spend the first part of their lives, making the atoll ecosystem an especially promising site to study shark behavior and development under natural and nearly pristine conditions.

“In most parts of the world, shark populations have been heavily impacted by people,” says Professor Wirsing, who got to spend 10 days on the atoll in August. “So what tantalized us about Tetiaroa is that it’s close to Tahiti and fairly easy to reach, yet at the same time it’s remote enough to have very little human contact.”

Tetiaroa

Located about 33 miles north of Tahiti, the atoll of Tetiaroa consists of a string of coral islets surrounding a shallow lagoon.

French Polynesia, after all, is a collective of more than 100 islands spread out across a vast water area about the size of Western Europe, though with a total land area only about as big as Rhode Island. Within this sprawling network of archipelagos, moreover, sharks play an important role in traditional and modern Polynesian culture, and the government has established a moratorium on shark fishing. The result is effectively the world’s largest shark sanctuary, about half the size of the United States, making Tetiaroa a paradise for the sharks that live there—not to mention for the researchers who get to study them in this stunning natural laboratory.

Quite a Site
The unique conditions of an atoll ecosystem require an enormous amount of time and very particular geologic circumstances to form. On Tetiaroa, that work started millions of years ago when volcanic upwelling created a land mass above sea level. Coral slowly formed around the edges of the island, and while the volcano eventually became inactive, the coral continued to grow, maintaining its structural shape even as the volcano gradually disappeared under the ocean. In time, all that survived of the original upwelling was a barrier reef surrounding a turquoise lagoon, which floats like a tropical wading pool in the middle of the Pacific Ocean.

How Tetiaroa evolved as a base for research operations—and how Wirsing got hooked into this project—began far more recently with the filming of Mutiny on the Bounty in 1961, when actor Marlon Brando first visited and quickly fell in love with the atoll. He ended up buying it in 1967, in fact, and aimed to preserve the natural wonders and biodiversity of the ecosystem.

Brando envisioned Tetiaroa as an ideal location for a luxury eco-resort and a small scientific community to support research and conservation efforts on the island. Though Brando never got to see his dream come to life, his estate—The Marlon Brando Living Trust, which owns Tetiaroa—has recently implemented much of that vision working with two partners: Pacific Beachcomber, which just opened The Brando, a highly exclusive eco-resort (where accommodations start around $3,600 a night), and Tetiaroa Society, a nonprofit scientific and cultural organization that now operates a research facility on the atoll.

Blacktip reef shark

Most juvenile reef sharks in the lagoon, like this blacktip, are about 1.5 feet long, though adults can grow larger than 5 feet.

Last year, in anticipation of The Brando’s opening, David Seeley of Tetiaroa Society reached out to the College of the Environment and expressed interest in bringing more researchers out to Tetiaroa. A number of projects are already under way on the atoll, including the work of Oceanography professors Julian Sachs and Alex Gagnon, as well as recent Oceanography alumna Lauren Brandkamp, measuring the effects of ocean acidification on coral reefs. Another big project Seeley targeted—to be funded through a donation from his parents, Jim and Marsha Seeley, of Medina, Wash.—involved studying the atoll’s large population of sharks, including lemon sharks (Negaprion brevirostris) and blacktip reef sharks (Carcharhinus melanopterus).

Sharks tend to reproduce in remote areas that are hard to research, and many coastal areas that might have once served as nurseries have been degraded or destroyed. But Tetiaroa’s shallow lagoon—protected from the open ocean and only a couple feet deep in most places—provides a relatively safe habitat for juvenile reef sharks to learn and mature for roughly the first year of their lives before venturing out as adults. That sheltered basin, in short, can open a special window into the shark world. So when the College approached Wirsing about the possibility of setting up a shark research program on Tetiaroa, he jumped at the chance.

“Our work on Tetiaroa can help establish a vital baseline for how healthy reef shark nurseries function,” he says.

Diving Deeper
Wirsing’s first job was to assemble a team of international shark experts. Though much of his current focus is on terrestrial ecosystems, his doctoral research involved the effects of tiger shark (Galeocerdo cuvier) predation on dugongs (Dugong dugon) in Australia’s Shark Bay, so right away he brought in a long-time collaborator on that project, Professor Mike Heithaus from Florida International University (FIU). Heithaus, who hosted the National Geographic Crittercam television series from 2002 to 2003, runs the Marine Community & Behavioral Ecology Lab at FIU, and one of his postdocs, Jeremy Kiszka, has also joined the Tetiaroa crew. The other principal researcher is Dr. Johann Mourier from the Insular Research Center and Environment Observatory (CRIOBE), based in Moorea, French Polynesia.

Tetiaroa

Their next task was to establish whether Tetiaroa would in fact be a good base to set up a shark study, so Wirsing, Kiszka and Mourier spent 10 days on the atoll this past August. While they weren’t lucky enough to get a room at The Brando, the Tetiaroa Society Ecostation itself is an impressive installation, offering cozy lodging and lab space for scientists and students from around the world. (It also features a number of green innovations, including a Sea Water Air Conditioning system that pulls cold water from the deep ocean to provide low-energy cooling for all the buildings on the island, as well as a biofuel power station that runs on locally produced coconut oil.)

They initially set out to answer some very basic questions about the lagoon ecosystem, such as what kinds of sharks live there, how many there are, and why they’re using the lagoon. Since the lagoon is only seven kilometers across, the ecosystem is small and contained enough to map and study in its entirety—potentially to the point of counting every shark in there. Yet given the limited time of the pilot season, the team decided to focus on surveying and mapping two of the largest nurseries to get a sense of their physical structure.

Using a combination of aerial drone photography and underwater videography with stationary cameras, they were able to generate a wealth of spatial and population data. The drones allowed the researchers to run multiple transects over the water, providing a broad sweep and bird’s-eye view of the lagoon and its fish communities. The underwater cameras, meanwhile, captured a more localized and detailed look at the nursery environment (including the footage below of a curious blacktip reef shark jostling the camera!).

This first field season was fairly limited, and the researchers are still working through the data they collected. Yet thanks to another donation from the Seeley family, they’ll be returning to Tetiaroa this summer for a second trip. Professor Heithaus, who couldn’t make the first visit, will be joining the team and helping expand the operation. “This time we hope to actually catch, measure and sample the tissue of sharks to get a sense of what they eat,” says Wirsing, and down the road they might also be able to equip juvenile sharks with tracking technology so they can study their behavior and movements after they leave the nurseries.

“These nurseries are critical to reproduction,” he says. “One of our ultimate goals is to use this ecosystem as a reference point to guide restoration of areas that might someday serve as shark nurseries again, so the conservation implications are huge.”

Director’s Message: Winter 2015

Last weekend, I woke up early and pored over newspapers and websites looking for a place to ski with my sons. I was extremely disappointed to see rain again forecasted for Snoqualmie Pass, with more rain predicted in the next two days, all the way up to 6,000 feet. A few ski areas were open, but those that were had limited runs available, or the conditions were icy and ragged and threatened to tear up your skis. Another time of year, such a soggy forecast would be welcome news. But it was a grim outlook for the first weekend in January.

As an avid alpine and Nordic skier, I am acutely aware of the poor early-season snow conditions that have plagued the Pacific Northwest since my family moved here in 2012. As a natural scientist, I am also keenly aware of the complexities of regional weather patterns, and I have to resist the temptation to ascribe all poor ski conditions to a warming climate. At the same time, climate change is predicted to bring warmer, wetter winters to the region, and the existing conditions at Snoqualmie Pass are bearing that out. I know some might chide me and argue that a shortened ski season is hardly cause for global panic. Yet the effects of our warmer winters will eventually ripple throughout the natural resources sector, threatening forest productivity, widespread insect outbreaks, stand-replacing fires, mudslides and all sorts of critical wildlife habitat, including salmon-spawning streams.

UW Climate Change Video Contest

In our first-ever Climate Change Video Contest, we are asking high school and undergraduate students in the state of Washington: What does climate change mean to you?

I couldn’t sleep later that night, and I found myself thinking about personal responsibility and how we can inspire collective action. Scientists have long understood and attempted to communicate the risks of CO2 emissions from fossil fuel burning, and the links between our behavior and climate change are very real and well-documented. Yet after decades of trying to build awareness, we have largely failed to move the voting public or our elected leaders to take determined action. During the holidays, I even read several reports that the recent downturn in gasoline prices has spurred higher sales of larger, fuel-consumptive vehicles. This type of short-term thinking reflects the gulf between what we’re constantly warned about climate change, and how we actually react as citizens.

The most frustrating part for me is wondering why these warnings won’t stick, so maybe we need to rethink our approach. Maybe we need to change the message. Or maybe we just need to change who is delivering the message and give prominent voice to younger generations—the future leaders who will inherit and confront the greatest impacts of climate change.

With that goal in mind, this year we are trying a new approach to addressing the climate issue. Rather than asking our scientists to tell a story of modeled predictions of a warming climate, we are hosting a video contest that challenges high school and college students in the state of Washington with a simple prompt: What does climate change mean to you? In the space of three minutes or less, they can approach the issue through virtually any artistic style. How to make this climate message resonate on a personal and actionable level, after all, is all that matters at this point.

So I’m really looking forward to seeing how students frame this issue. I’m excited to see what inspiration and ideas we can draw from them in communicating—and solving—the enormous environmental challenges ahead of us.

I’ll keep eyeing the forecast and hoping for more snow, of course, but always in the much broader context of achieving a sustainable balance with a changing climate and world.

Happy trails,

A Family Affair: Four Manuwals Co-Author Paper

This past October, Professor Emeritus Dave Manuwal had a new paper published in Northwest Science, “Progressive Territory Establishment of Four Species of Neotropical Migrants in Linear Riparian Areas in Western Montana.”

Dave Manuwal

Manuwal’s daughter, Joy Burke, helping with bird surveys in 2008.

The scope of the research alone should grab your attention, as it spanned 40 years from 1968 to 2008, starting from his time as a graduate student at the University of Montana. Take a look at the author list, though, and you’ll see what really distinguished this particular publication for Manuwal: He was able to include his wife, daughter and son in the research, and all four are co-authors on the paper!

“When I decided to re-survey my old Montana study areas,” he says, “I realized this would be a unique opportunity for me to involve my whole family in the effort. It turned out to be one of my most rewarding professional experiences. My wife Naomi helped me with the study in 1968, 1980 and 2008. She has a forest ecology background, so she helped with the plant sampling. My daughter Joy has learned how to identify birds, and she came out in 2008 to help me conduct bird surveys. While doing a bird survey one morning, she happened to flush a mountain lion along a riparian area she was surveying. It was very close! My son John also came out to help mark my study sites for bird and vegetation surveys. It was in early April and it was very cold—about 13 degrees—with lots of snow in places. It was hard work, but enjoyable!”

Manuwal’s wife Naomi, who worked on the study with him in 1968, 1980 and 2008, earned a master’s in forest ecology from SEFS in 1976.


Humans Adding ‘Fossil’ Carbon to Rivers

Though soil has often been considered a reliable long-term carbon sink, new research suggests that the effects of human land-use choices—from urbanization to agricultural intensification and deforestation—are reducing how much carbon is actually stored in the ground, says Professor David Butman, lead author on a paper just published in Nature Geoscience, “Increased mobilization of aged carbon to rivers by human disturbance.”

Professor David Butman

Professor David Butman

Professor Butman is a new faculty member with the School of Environmental and Forest Sciences (SEFS) who holds a joint appointment with Civil and Environmental Engineering. He began this research in 2011 as an offshoot of his doctoral work at Yale University involving 13 major river basins in the United States. Starting from a trend he discovered in that initial data, Butman and his co-authors expanded the scope with direct sampling of aquatic carbon at a number of field sites around the world, and also combed the literature for other relevant studies, tracking down researchers whenever possible to verify data. The resulting study range covers 84 degrees of latitude from the Arctic to tropical ecosystems, providing a comprehensive, global data set of radiocarbon ages of riverine dissolved organic carbon, coupled with spatial data on land cover, population and environmental variables.

From exploring this data, Butman and his co-authors were able to determine how carbon isotopes of organic matter in rivers can show the impact of land cover disturbances—specifically, the release of ‘old’ carbon into the modern carbon cycle, analogous to the burning of fossil fuels. Most dissolved organic carbon in rivers originates from young organic carbon from soils and vegetation, but the results of this study suggest that 3.2 to 8.9 percent of that dissolved organic carbon is actually aged carbon that human disturbances have churned back into the system.

What that means, says Butman, is that the release of carbon through land use and land cover change has been undercounted in previous estimates of anthropogenic carbon emissions. The full impact of this increase on the global carbon cycle is not entirely clear yet, but it definitely means we’re reducing how much carbon is being stored in the land purely through how we manipulate and change the physical surface of the planet.

Check out the full results and conclusions in the paper, and contact Professor Butman if you have any questions about this research or his other projects!

Miller Seed Vault Donates Seeds to Time Capsule

For the 125th anniversary of Washington’s statehood, the UW Botanic Gardens has donated the seeds of five rare plant species—all native to Washington—from the Miller Seed Vault to be buried in the Washington Centennial Time Capsule.

The time capsule is located in the Washington State Capitol in Olympia. It’s a large green safe with 16 individual capsules, one of which will be filled every 25 years until the state’s 500th birthday in 2389. The 2014 capsule will be loaded this January and then resealed during a ceremony on February 22, 2015, George Washington’s birthday.

Time Capsule

Thompson’s clover, a unique clover found in the central part of Washington, is easy to spot in May among the perennial bunchgrasses and sagebrush.

Back in November, the Keepers of the Capsule, a volunteer group that helps steward the capsule project, had reached out to the UW Botanic Gardens to inquire about a possible donation of native seeds. Professor Sarah Reichard and Wendy Gibble, who manages the Washington Rare Plant Care and Conservation program, decided that an appropriate contribution would include bundles of seeds that represent plants from different habitats across the state. They were careful to select seeds that are rare and endemic to Washington, but that are not in short supply in the Miller Seed Vault (just in case the seeds don’t last 375 years in an airtight aluminum foil package!).

The five selections include Thompson’s clover (Trifolium thompsonii) from the shrub-steppe of central Washington; Barrett’s beardtongue (Penstemon barrettiae) from the basalt cliffs of the Columbia River Gorge (pictured below); Washington Polemonium (Polemonium pectinatum) from the channel scablands of eastern Washington; Victoria’s paintbrush (Castilleja victoriae) from a tiny island in the San Juans; and Whited’s milk-vetch (Astragalus sinuatus) from a 10-square-mile region south of Wenatchee, Wash.

Each bundle includes 20 seeds and comes with specific instructions about propagation, as well as general information about the plant’s characteristics and where the seeds were collected. Will these seeds be alive and well in 2389? Hard to say, says Gibble, but it’s a shame we won’t be there to see for ourselves!

Field Work Day at Pack Forest

Two weeks ago, right after the first snow of the season, SEFS graduate students Matthew Aghai and Emilio Vilanova joined Dave Cass and Pat Larkin down at Pack Forest for a field work day at the Canyon Loop site within the “Through-fall Exclusion” project.

Pack Forest

Dave Cass climbs a tower near the Canyon Loop site to work on a frozen component.

The main goal of this research is to simulate the conditions of drought and its effects on managed forests with different stand conditions, and several members of Professor Greg Ettl’s lab—mostly led by Kiwoong Lee—have been installing panels and collecting detailed measurements of many bio-climatic variables, including soil moisture, tree growth, precipitation and temperature, among other factors.

While working at the site on December 1, Vilanova took advantage of the first snow and open skies to snap a few shots of the action, including the awesome view of Mount Rainier below, taken a few yards from the Canyon Loop site!
