QUIETING THE CRY OF THE WILDERNESS

Loons, whose haunting calls are a hallmark of the northwoods, may be at serious risk from an activity beloved by many wilderness visitors.

"Loons are not fans of canoes," says Joseph Kaplan, who is completing his master's degree in forestry. "We are finding that recreation, especially canoeing, on Isle Royale's inland lakes seems to be having an impact on productivity."

Kaplan has been studying the nesting behavior of loons at Isle Royale National Park. Located in Lake Superior, the 850-square-mile island is America's least-visited national park, which, ironically, may make its loons more vulnerable to human disturbance.

"Isle Royale's inland lakes are wilderness lakes and have nonmotorized use only," Kaplan explains. "Use levels aren't high. But the loons may not get used to people's patterns, so when people do show up, the loons overreact."

This overreaction takes the form of abandoning their nests and any eggs therein. Often enough, the parents never return, and the eggs never hatch.

It doesn't take much to spook a loon. Many pairs leave their nests when they notice people as far as 150 meters away. "I've seen them flush 275 meters away," Kaplan says.

What makes loons so vulnerable to canoes is their aquatic nature. Unlike ducks and geese, loons can't walk on dry land, so their nests must be on the water's edge. That puts them near canoe routes and portages.

The good news is that when people are kept away, the loons rebound quickly. Last year, the National Park Service moved a portage in Isle Royale National Park away from a loon nest site, and the pair stayed on their nest. And when canoes are warned away from nesting areas by buoys, loons are more likely to hatch their eggs.

"That's exactly what you want to see," Kaplan said. "In the absence of canoe use, we predict about 70 percent of nests will be successful."

Kaplan sees the loons' vulnerability to disturbance as a cautionary tale in the annals of natural resource management.

"It's kind of assumed that wildlife are protected in wilderness areas," he says. "That's not necessarily true."

"This is one small story to add to the growing body of evidence that protection doesn't necessarily guarantee conservation," says Kaplan. "The remedy is informed management.

"It will be interesting to see how far people will go to protect those values that prompted us to create wilderness areas in the first place."

"Long-term studies like these help us make good management decisions," said Phyllis A. Green, Isle Royale National Park superintendent. "We were pleased to support this study, which revealed important information about a species in decline."

In conducting his research, Kaplan relied in part on 12 years' worth of data collected by the National Park Service on the number of loon chicks hatched on the island. He compared that data with information on the number of back-country canoe and kayak permits issued since 1991.

The survey of loon chicks is undertaken every summer by park service staff and volunteers, including Kaplan, who has been observing loons at Isle Royale for 10 years.

Kaplan's research is funded by the National Park Service, the North American Loon Fund, the Sigurd Olson Environmental Institute and Bonnie Robbins.

MICHIGAN TECH TEAM QUALIFIES FOR INTERNATIONAL CODE-WRITING CHAMPIONSHIPS

Three computer science students have earned the right to compete in the biggest computer code-writing contest in the world.

Undergraduates Joe Nievelt and Patrick Williams and master's student Kyle J. Rokos will go to Prague in March for the 28th Annual ACM International Collegiate Programming Contest World Finals.

They are among 72 teams to advance to the finals. All rose to the top in dozens of regional ICPC contests, which draw thousands of college students from around the world.

"It's very exciting," says Linda Ott, chair of the Department of Computer Science. "We have some top-notch programmers here, and it's fun to see them get this far.

"They really are world caliber, and it's great to see them get this recognition."

To qualify for the world finals, they excelled in the ACM North Central North America Programming Contest, which drew 177 teams from 70 colleges and universities. The MTU team will be joined in the Czech Republic by a team from the University of Wisconsin at Madison, which was the top scorer in the regionals.

Associate Professor David Poplawski (Computer Science) coached the students in preparation for the contest, but he declines credit. "They got most of their talent independent of the little practices I hold," he says. "It's a tremendous honor for them."

HOW BEETLES BEAT THE PESKY PURPLE PLANT PROLIFERATION

by Laura Walikainen, student writer

A team of Michigan Tech faculty recently defeated an unlikely invader: a pretty purple flower.

Rolf Peterson, a professor in the School of Forest Resources and Environmental Science, noticed that there was a population of purple plants taking over the pond near Houghton High School, across from the Michigan Tech Employees Federal Credit Union. He identified them as purple loosestrife, a perennial wetland plant known for its heartiness and stability. The cattails native to the wetland were being out-competed and were beginning to disappear from that environment.

Purple loosestrife is an exotic species that, when introduced to a new area, can take over the natural environment. Exotic species, because they are out of their natural habitat, often have no natural competitors or predators.

"They typically don't have the predators and competitors with which they evolved, and then the plant population grows out of balance," said Leah Vucetich, a research assistant professor in the School of Forest Resources and Environmental Science who worked on the purple loosestrife problem. "Their population explodes."

At a height of three to 10 feet, each adult plant has the ability to produce three million seeds a year. This makes purple loosestrife very difficult to get rid of.

"People have tried flooding the plants, burning them and spraying them with chemicals," said Vucetich, "but none of these have worked all that well... or, if they have, without compromising the surrounding environment. People have even tried mechanical hand-pulling, but this is very labor intensive. It's also not very feasible on a large scale. It's estimated that a total of $45 million dollars is spent every year trying to unclog waterways where purple loosestrife has invaded."

So scientists in other areas stricken with purple loosestrife have tried using biological controls to combat the problem. Biological controls have created debate because they are basically introducing another exotic species into an area to deal with the original exotic species. But a specific beetle, Galerucella calmariensis, whose natural predator is the ladybug, has been found to have great success in controlling purple loosestrife invasions.

Vucetich and her husband, John Vucetich, a fellow research assistant professor in the School, heard about a scientist at Michigan State University who was raising these beetles for use as a biological control. The Vucetiches headed downstate and returned with 20 pots of purple loosestrife stumps on which 50 to 100 beetles were living. Ten pots of beetles were released at the Houghton High School pond, and 10 were released along the Pike River Bridge, where there was also a purple loosestrife problem.

"We released the beetles in the summer of 1998, and by 2002 only one purple loosestrife plant could be found near the Houghton High School pond," said Leah Vucetich.

"Biological controls are fairly controversial and the outcome is not always certain," said Leah Vucetich. "But this situation was well researched before use of beetles was allowed in the United States. The beetles had a dramatic effect and worked great at the pond."

CHEM-E CAR TAKES SECOND PLACE IN THE NATIONALS

by Megan Gilge, Tech Topics editorial assistant

Michigan Tech's Chem-E car team rode to its best finish ever in national competition, taking the silver at the AIChE finals held Nov. 16 in San Francisco.

The MTU team finished second among 25 top teams from across the U.S.

"It was my 30th birthday," said the group's advisor, Assistant Professor Jason Keith (Chemical Engineering). "It was a nice present."

Competitors built shoe-box-sized model cars powered by chemical reactions--no Energizer batteries allowed. The goal was to make the car travel a specific distance, stopping as close to the finish line as possible.

The MTU team's car is powered by a hydrogen fuel cell and has a custom machined copper body to represent the Copper Country.

The team also received an award for most consistent performance, with two runs of almost exactly the same length. "They were the only school in the competition to do that," Keith said. "They worked pretty hard trying to perfect their design. You never know what will happen. They tested in the building under certain conditions, but then there was this ballroom with the bumpy floors."

After taking ninth place in the 2001 competition, the team wanted to replace their original Tupperware-framed, battery-powered car with something new. They became one of the first groups to use hydrogen fuel cells in the Chem-E Car competition.

They also wanted to involve students in other disciplines.

This led to the creation of the Fuel Cells and Alternative Fuels Enterprise, which is sponsored by the United States Army, Tank Automotive and Armaments Command. In addition to working on the Chem-E car, the Enterprise is developing a "Mule." The ground vehicle may weigh up to a ton and will include a fuel cell to provide at least 20 minutes of silent propulsion. For more information, visit http://www.enterprise.mtu.edu/eteams/Alternative_Fuels_Group.html.

Students who represented Michigan Tech at the conference were Kevin Lamkin (head of the Chem-E car team), Jeremiah White, Lemayian C. Kimojino, James Eickhoff, Adetoun Ayorinde, Nicholas Ballor, Clint Wininger, Mike Scudder, Hugh Simmonds, Jonathan Jelsma, Abram Walters, Andrew Pressler, Matthew Guyton, Rachel Smith and Jesten Neill. Other MTU students who worked on the design and construction of the car were Kenneth Koers and Jeremiah McConnell.

The Chem-E team's sponsors included BASF, USG, the Michigan Tech Fund's Parents' Fund, the Department of Chemical Engineering, and the AIChE MTU chapter. The first place team was from the University of Dayton.

NOMINATIONS SOUGHT FOR FACULTY DISTINGUISHED SERVICE AWARD

The Faculty Distinguished Service Award Committee is now seeking nominations for the 2004 award. The deadline for nominations is Friday, Feb. 20.

The award is open to all full-time faculty, including lecturers and research faculty. Those who hold restricted appointments (e.g. adjunct, visiting, temporary or part-time faculty) as well as faculty who hold positions with a significant administrative component (e.g. deans, associate deans, department chairs etc.) are not eligible. The award will be presented at the President's Convocation in the fall.

The Faculty Distinguished Service Award recognizes service to the University community that has significantly improved the quality of some aspect of campus life. The work could have resulted, in part, from compensated efforts, but it must have been of a quality that distinguishes itself above and beyond the normal execution of those tasks. The award is intended to recognize exceptional service in one area rather than integrated service. It is not a lifetime achievement award.

Nominations will be accepted from any member of the university community including staff, students and alumni and should be received by the committee by Feb. 20. To make a nomination, fill out the nomination form (available at http://forest.mtu.edu/fdsa/) and submit it together with any applicable supporting material to Blair Orr, Faculty Distinguished Service Award Committee, School of Forest Resources and Environmental Science. Include a description of the specific work for which the candidate is being nominated; an explanation of why the work merits the award, including a description of how the university has changed as a result of this work; a model inscription to be placed on the award; and any appropriate supporting materials.

TEACHING AT TECH: HOW THE MIND WORKS (PART 2)

by William Kennedy, director, Center for Teaching, Learning and Faculty Development

Steven Pinker, professor of psychology and director of the Center for Cognitive Neuroscience at MIT, says the human mind might be productively thought of as a set of specialized learning modules. "Our physical organs owe their complex design to the information in the human genome, and so, I believe do our mental organs," Pinker writes.*

Pinker defends his position by appealing to converging lines of evidence from widely diverse sources. Artificial intelligence researchers realize that creating machines that emulate sophisticated processes routinely undertaken by humans requires devices literally packed with various sorts of computation systems tailored to simultaneously solve very different kinds of problems.

Pinker notes that biologists and psychologists find that identical twins, even when reared apart from birth, exhibit remarkable similarities even down to the finest structures of their personalities. Pinker writes that often "they are alike in talents such as spelling and mathematics, in opinions on questions such as apartheid, the death penalty and working mothers, and in their career choices, hobbies, vices, religious commitments and tastes in dating." Fraternal twins reared apart are markedly less alike that identical twins, again suggesting the likely impact of genetic influences on our neurological inheritance and subsequent mental processes.

Pinker argues that learning, itself, "is made possible by innate machinery designed to do the learning." He says that the "evidence suggests that humans everywhere on the planet see, talk, and think about objects and people in the same basic way. The difference between Einstein and a high school dropout is trivial compared to the difference between the high school dropout and the best robot in existence, or between the high school dropout and a chimpanzee." Pinker, an unapologetic Darwinian, says it seems obvious that eons of natural selection have formed the foundation of our shared inherited mental hardware.

Pinker says fetal mental development occurs according to some complex genetic recipe whereby a ball of identical cells differentiates, triggered by an intricate combination of chemical, mechanical, and molecular cues built into the genome itself. In the sensory areas of the brain, neurons appear just at the right time and migrate to the right places and begin linking with their intended targets. These fundamental genetic processes shared by virtually all human beings make it possible for babies to see at birth.

From the very beginning, according to Pinker, brain development is affected by the nature of the tissue, the position of that tissue, and the pattern of triggering inputs passing through that tissue during the development process. We are so predictable in our neurological development, he says, that doctors routinely assess neurological normalcy by eliciting responses along anticipated lines of connection.

If we do, indeed, inherit a common set of mental machinery programmed to process information in preset ways, understanding the nature of this processing should help us to create environments and inputs to facilitate the desired changes in mental functioning we commonly refer to as learning. Perhaps the cognitive sciences will one day help us to produce learning environments that have more impact and are better attuned to the developmental needs of our students.

KSO PRESENTS "SEASONAL SPIRITS OF MYSTERY AND MAGIC" SATURDAY

The Keweenaw Symphony Orchestra and the Michigan Tech Wind Symphony join forces on Saturday, Dec. 6, to celebrate the holiday season in "Seasonal Spirits of Mystery and Magic," a joint concert featuring more than 100 musicians. Alton Thompson will conduct music from John Williams' "Harry Potter Suite," Tchaikovsky's "Nutcracker," Leroy Anderson's "A Christmas Festival" and David Bobrowitz's "Chanukah Celebration" at 7:30 p.m. in the Rozsa Center.

The Dec. 6 concert celebrates different facets of the mystery and magic of the season. Bobrowitz's "Chanukah Celebration" features traditional songs of Judaism's Festival of Lights, while Anderson's "Christmas Festival" combines both sacred and secular melodies associated with the Yuletide season. "The Nutcracker," based on a tale by E. T. A. Hoffman, has remained an audience favorite for over a century, as ballet companies throughout the world recreate the magic of Christmas Eve and the kingdom of the Sugarplum Fairy.

The themes composed by John Williams for films based on the Harry Potter novels of J. K. Rowling also enjoy wide popularity, far beyond even the legions of avid young readers. Thompson has remarked that "the greatest magic performed by Rowling's young wizard may be the way he charms young persons all over the world into turning off computers and television sets to seek adventure in the pages of a book. Or even, perhaps, a concert."

"The season of the year when days grow shortest has seemed charged since ancient times with a sense of mystery and promise," Thompson observes. "The long nights hold the possibility of new light, and miracles seem close at hand. Here ancient Mesopotamia placed its new year and here every world religion celebrates a feast of renewal. It's a time when families gather themselves to the hearth, and when the play and imagination of children hold special meaning."

Tickets for "Seasonal Spirits of Mystery and Magic" are available from the Rozsa Box Office (487-3200, http://www.tickets.mtu.edu), other university box offices and at the door for $15 general, $6 students.
