Leading quantitative conservation biologist named CU’s first Colorado Chair in Environmental Studies
Oct 1st
The University of Colorado Boulder has hired its first Colorado Chair in Environmental Studies, an endowed chair awarded to Daniel Doak, a conservation biologist known for his quantitative analysis of how different government policies could affect the populations of species ranging from sea otters, California condors, corals and rare plants.
The endowed chair in environmental studies was made possible by $4 million in gifts made anonymously in 2009 and 2010 toward the chair.
Dr. Daniel Doak
Sharon Collinge, professor and director of the CU-Boulder Environmental Studies Program, called Doak a perfect match. “He epitomizes what we’re looking for,” she said.
Doak is especially skilled in interdisciplinary research, she said. He brings expertise in policy to his analyses of risks of energy development, for example. And he is widely cited for his research in quantitative conservation biology, which combines sophisticated computer modeling with varying policy scenarios to project changes in populations of rare species.
For instance, the Proceedings of the National Academies of Science recently published a study co-authored by Doak concluding that the California condor is chronically endangered by lead exposure from hunters’ spent ammunition.
While the free-flying condor population has risen in the last three decades, that increase has been achieved through captive breeding, monitoring and veterinary care, the study found. Meanwhile, the primary threat to the endangered bird — lead poisoning from bullets and shotgun shells lodged in carrion — has gone largely unmitigated, the study said.
Doak and his fellow researchers found no evidence that California’s 2008 partial ban on lead ammunition yielded any decrease in lead exposure and poisoning in condors.
Since 2007, Doak has served as a professor of zoology and physiology at the University of Wyoming. Previously, he was a faculty member at the University of California, Santa Cruz. His research has been funded by the National Science Foundation, U.S. Fish and Wildlife Service, U.S. Forest Service, California Department of Fish and Game and the U.S. Bureau of Land Management. Scholarly papers have cited his work more than 3,000 times since 1998.
Doak said he was drawn to CU-Boulder’s Environmental Studies Program because of its breadth, spanning disciplines ranging from biogeochemistry to political science to philosophy. This interdisciplinary focus is necessary to confront some of the world’s most intractable problems, Doak and Collinge said.
“That’s the only way we can really address and resolve some of the major environmental challenges that we face,” Collinge said.
Working with experts from a wide range of disciplines, Doak added, provides a motivation and opportunity “not once a year but every day to confront your own ignorance and thus to appreciate and learn new ideas and approaches.”
It is not that interdisciplinary work is always best, he added. “We need to train ourselves and our students to determine when the problem we are confronting requires an interdisciplinary approach. If you want to build a bridge that won’t fall down, you don’t need an interdisciplinary team. You need a good engineer.”
The critical question, he said, is the following: “Is this problem a nail that requires a hammer, or is this a problem that requires a lot of tools? And most environmental problems require an entire chest of tools and the different people who know how to use them.”
Collinge said students sometimes grasp this distinction better than professors do. “Students who are interested in the environment understand very deeply that they have to know something about politics and policies and how we make choices and why we make choices,” she said. “They’ve essentially pushed us, encouraged us to provide that broad and deep training for them.”
Of the donor’s gift, Collinge said, “This was incredibly generous. And we are really grateful.
“For me, it validates or speaks to the importance of what we’re doing,” she said. “With more than 1,000 undergraduate majors in environmental studies and 50 graduate students, enthusiasm was abundant even before the gift that enabled the endowed chair.”
NSF AWARDS CU-BOULDER $5.9 MILLION GRANT FOR ALPINE ECOSYSTEM RESEARCH
Jun 16th
The National Science Foundation has awarded the University of Colorado Boulder a six-year, $5.9 million grant to continue intensive studies of long-term ecological changes in Colorado’s high mountains, both natural and human-caused, over decades and centuries.
Awarded to CU-Boulder’s Institute of Arctic and Alpine Research, the renewal grant will allow faculty and students, including undergraduates, to continue key environmental studies at the Niwot Ridge Long-Term Ecological Research, or LTER, site west of Boulder. The study site, considered extremely sensitive to climate change, is adjacent to CU-Boulder’s Mountain Research Station and encompasses several thousand acres of tundra, talus slopes, glacial lakes and wetlands stretching to the top of the Continental Divide.
The grant is the largest environmental sciences award in CU-Boulder history, said INSTAAR Fellow Mark Williams, principal investigator on the grant. In 2005, NSF awarded CU-Boulder a $4.9 million renewal grant for environmental studies at the Niwot Ridge site. As one of five initial LTER sites selected by NSF in 1980, Niwot Ridge is now one of 25 such sites in North America and the only one located in an alpine environment, said Williams.
“CU-Boulder has a worldwide reputation for monitoring global climate change from Greenland to Antarctica and its impacts on natural ecosystems and human populations,” said Vice Chancellor for Research Stein Sture. “To direct such a key program in our own backyard for the National Science Foundation is crucial from an environmental science standpoint and unique in that it provides a spectacular training ground for our students to work side-by-side with some of the world’s best climate change scientists.”
Recent climate studies have predicted the mountainous areas of the American West will become both hotter and drier in the coming years, and long-term meteorological measurements on Niwot Ridge indicate the alpine climate there has warmed slightly in recent decades, said Williams, also a professor in the geography department. The temperatures are significant because even small changes in alpine ecosystems can cascade down and have negative effects on other ecosystems, he said.
CU-Boulder researchers also have charted a doubling in atmospheric nitrogen deposition on Niwot Ridge in the past several decades — primarily from automobile, agriculture, ranching and industrial activity — that is now adversely affecting some aquatic and terrestrial life on the ridge, said Williams.
In addition, researchers are keeping a close eye on existing populations of the American pika, a potato-sized animal related to rabbits and found in rocky talus slopes as high as 13,000 feet on Niwot Ridge. Of 25 populations of pikas in the Great Basin of Nevada documented between 1898 to 1990, nine had disappeared by 2008, apparently the result of warming temperatures. Pikas in Colorado require deep snowpack during winter that serves to insulate them from extremely cold air temperatures, Williams said.
“Many consider the American pika a ‘sentinel species’ in terms of measuring the effects of climate change,” said Williams. “Niwot Ridge has a cold, short growing season, and the biological activity that occurs there is on the razor’s edge of environmental tolerance.”
Despite a long-term warming and drying trend in mountainous areas of the West, 2011 was a striking anomaly, said Williams. “What we have seen around here is one of the largest and latest snowfall years on record in the high country and extreme dryness accompanied by an inordinate amount of winter wildfires around Boulder, which is only 15 miles as the crow flies from the Niwot Ridge study area. What has happened from Boulder west to the Continental Divide has been a total disconnect in terms of weather.”
“The primary climate driver of the Niwot Ridge site is snow, and the mountains are our water towers,” said Williams. “As the alpine climate changes, one of the biggest impacts on humans will be a change in water resources. Even if we end up with the same amount of precipitation, in the form of less snow and more rain, we are going to end up with less usable water for municipalities.”
There already are some indications that the snowline in the Rocky Mountains is moving upward, which will affect the abundance and distribution of plants and animals and likely shorten the annual ski seasons at resorts throughout the West in the future, he said.
The Niwot Ridge site is a huge benefit to CU-Boulder students, said Williams. “I have five undergraduates working in my chemistry lab this summer. Not only do they get paid, but they learn valuable research skills.” The LTER grant funds research for about 15 CU-Boulder graduate students and 25 to 30 undergraduates annually, Williams said, and there are more than a dozen CU-Boulder faculty members that are co-investigators on the new Niwot Ridge LTER program grant.
CU-Boulder ecology and environmental biology department Professor William Bowman, director of CU-Boulder’s Mountain Research Station for the past 20 years, said the Niwot Ridge site has been gaining momentum in stature from its beginnings by the consistent, high-quality research that has resulted in many publications in top-tier science journals.
More than half of the research on Niwot Ridge is by scientists and students from around the world that are not associated with the LTER program, said Bowman, also an INSTAAR fellow and who leads a team studying how air pollution, including nitrogen deposition, threatens biological and aquatic communities in U.S. national parks. There are currently 12 undergraduates conducting research at the Niwot Ridge site as part of the NSF’s Research Experience for Undergraduates program, said Bowman, who also is mentoring a student researcher at Niwot Ridge from Fairview High School in Boulder.
