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.”

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!”

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 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!

SEFS to Sponsor Orienteering Event on Campus

Think you know our campus? You can find out on Saturday, December 20, during an orienteering event right here on the UW campus!

Orienteering EventSponsored by SEFS and run by the Cascade Orienteering Club, this one-day event will help you discover more about your campus, the enjoyment of well-made maps, and your ability to make and trust your own decisions in unfamiliar situations.

Orienteering is the sport of navigating with a map and sometimes a compass. The goal is to find your way through a series of checkpoints marked on a map and flagged on the ground. No limed path to follow, no arrow signs, no GPS unit telling you what to do—just your own ability to track where you are and decide for yourself what route from checkpoint to checkpoint works best for you.

For this event, youth and adults from beginner to expert are welcome to participate recreationally or competitively. You can register online for $13 by December 18, and then check-in is from 10 a.m. to noon at Gates Hall.

Learn more about orienteering and how to get involved!

John Marzluff to Kick Off Winter Lecture Series at Henry Art Gallery

This winter, Seattle Arts & Lectures is hosting a five-part series at the Henry Art Gallery, “Thinking Animals: Species, Power and the Politics of Care in the World.” Held on Friday evenings from January 9 through March 6, the talks will explore the histories, politics and cultural dynamics of how humans see and do not see animals in the world. Bringing expertise from wildlife sciences, animal welfare, geography, anthropology, literature and political science, the speakers will explore human-animal connections in a range of global and historical contexts, including Renaissance France, contemporary Peru, and urban and rural spaces in the United States.

At 7 p.m. on Friday, January 9, Professor John Marzluff will be giving the first talk of the series, “Welcome to Subirdia: Sharing our neighborhoods with wrens, robins, woodpeckers, and other wildlife.” Drawing from his latest book, Professor Marzluff’s lecture will feature an “optimistic discussion of the vast diversity of birdlife that has adapted to living in populated areas, and a variety of things we can do to create more hospitable environments for our winged neighbors.”

Other speakers include Wayne Pacelle, president and CEO of the Humane Society of the United States; Dr. Kathryn Gillespie (Geography, UW); Dr. Louisa Mackenzie (French and Italian Studies, UW); Dr. María Elena García (Comparative History of Ideas and International Studies, UW Seattle); and Dr. Tony Lucero (International Studies, UW Seattle).

This lecture series is presented in partnership with the University of Washington’s Critical Animal Studies working group, and it will be held in conjunction with an exhibition by Ann Hamilton that touches on themes of human and non-human animals. Tickets are $100 for admission to all five lectures, or $20 at the door for a single talk (box office opens at 6 p.m.). A 15 percent discount is available to SEFS attendees, as well, so contact Karl Wirsing for the discount code.

Tell Us: Who Was Your Favorite Professor?

In the last issue of Roots, our new alumni e-newsletter, we asked alumni to tell us about their favorite professors. Here’s what Patrick T. Nooney (‘71, B.S.), who lives in Missoula, Mont., shared with us:

“I have to use the plural. Each one at the College [of Forest Resources] challenged me in a different way, but there are two equally in my mind who challenged me how to think for myself and not accept the status quo: Professors Barney Dowdle and David R.M. Scott.

Professor Barney Dowdle

Professor Barney Dowdle

I was literally flunking Forest Economics despite reading the literature three or four times, and studying notes until 3 or 4 in the morning. I asked Professor Dowdle to let me out and try again later: He refused, of course. Then the final: I’m done, finished, nothing to lose, gut honest with the answers, then kick the bucket. I got an A. When I asked him about the mistake, he told me ‘No mistake. You learned the lesson I intended: How to think.’ That has been the number one lesson I have applied in life.

Dave Scott was ultimately my primary advisor. He challenged me and encouraged me to always think outside of the box, including the pursuit of the wild idea of using ecological principles as a basis for logging/land management decisions. He told me that was not exactly something anyone would pay a graduate student to work on, considering the implications. Still, he told me, ‘If you believe in it, I will back you all the way to the doctorate.’ I sometimes regretfully wish I had taken him up on the deal. I honor his trust and faith in my education.”

For the next issue of Roots, we’re asking alumni to tell us: What was your first job out of college, and what do you remember most about it? We’ll feature one or more response in the next issue of Roots, and also right here on the “Offshoots” blog. Please email submissions—of no more than 250 words—to sefsalum@uw.edu, and we’ll follow up to ask for a photo if your letter is accepted and published.
