IGERT Fellows Present Posters at IPY 2012

This past week six Dartmouth IGERT Fellows presented their work at the 2012 International Polar Year Conference in Montreal.  The five students who gave poster presentations spent time in front of their posters chatting with fellow researchers, educators, media and policy makers about their work and findings.

Check out the videos below to see Lauren Culler, Laura Levy and Ben Kopec giving a shortened version of their poster talk for the camera!

IGERTeer presents at 35th Annual Society of Ethnobiology Conference

Ethnobiology is the study of humans and their relationship to things biological, from plants to animals to nature itself. Sessions ranged from “Archeological methods” to “Traditional Ecological Knowledge and Ethnobiology in the 21st Century (and Beyond): Changes, Innovations, and Issues of Justice” to an entire session dedicated to Acai. The Archeological Methods session was fascinating — Linda Scott Cummings presented a chemical analysis of residues found on ceramic sherds (in this circle they are called sherds and not shards) as support for the use of a plant in the Euphorbia family (same family as your Christmas friend, the pointsettia) in Samoa over 2000 years ago. Another presenter, Caroline A. Dezendorf, used her master’s research to recreate various processes of preparing maize. Using heirloom varieties of maize, she found that those kernels which underwent a lyme treatment match those found by archaeologists. Steve Wolverton used skeletal remains of white-tailed deer to determine that increased hunting pressure resulted in larger deer (due to increased forage).

While there I presented my results from my 2011 field season in South Greenland (see previous post). I was happy to share with the audience that plant knowledge is not disappeared from Greenland, but instead is shared among a small community of enthusiasts. I am working with my collaborator, Lenore Grenoble at the University of Chicago, to pull our results into a manuscript for submission to a journal. Unlike ecology journals, ethnobotanical journals favor including all the data within a paper. So far our manuscript is 4 pages long and the table with the results of our interviews is 10 pages long.  I’ve never seen more table than paper in an ecology journal!

Every talk about the Arctic requires acclimating the audience to a different perspective of the globe, one where the North Pole is the center of our perspective.

We found that knowledge varies from merely knowing who is knowledgeable about plants within the community to extensive knowledge about collection, preparation, storage and use of plants. We documented 171 uses of plants, divided into 7 categories: beverage, craft, food, medicine, fuel, spice or condiment, and ritual. The majority of uses were as medicine (~25%), food (~23%), beverages (~14%), and craft (~12%). Beverages include mostly teas and three instances of fermented drink. The craft category includes funeral wreaths and decorative bouquets of dried and fresh materials, including fabrication of Christmas trees from Juniperus communis. Medicines are topical and internal. Fuel includes material for fire and candlewicks. Spices are those plants used during cooking; condiments are those that are added to food once cooked. Ritual describes uses connected with spiritual practices, in this case to cleanse the home of bad energy or ghosts. Our work indicates that while few individuals hold knowledge, it does persist within the community and plants are used today both traditionally and with Danish influence.

A stormy day in the Rocky Mountains.

One of the highlights of the trip was a field trip to Rocky Mountain National Park. The four hour bus ride allowed plenty of time to get to know other conference participants, including Steve Weber, the founder of SoE, and a paleoethnobotanist. His research investigates how and why people adopt subsistence strategies. What I appreciated most about our conversation was to learn that he uses techniques with which I am familiar thanks to my IGERT connection with Earth Scientists, but to ask very different questions. My IGERT colleague, Laura Levy, uses lake core samples to measure the past extent of the Greenland ice sheet. Steve uses them to understand climate and agricultural practices in Pakistan. It was empowering to jump right into a conversation with the founder of an esteemed society with full understanding of his methods. Thanks, IGERT!

The Arctic Heads to Montreal

IPY Montreal 2012

This week the polar community is taking over Montreal for the International Polar Year (IPY) Conference.  Since the Dartmouth Polar Environmental Change IGERT was born out of an IPY project in 2007, it seems fitting that a number of IGERT students are up here to present their research.  Moving from learning and researching to presenting and sharing their knowledge, just as the IPY Montreal theme, From Knowledge to Action, promotes.

Dr. Gro Harlem Brundtland’s opening keynote address

Yesterday morning the conference started off with a bang with an opening keynote address by Dr. Gro Harlem Brundtland, member of the UN Secretary General’s High Level Panel on Global Sustainability and former Prime Minister of Norway.  Dr. Brundtland’s work in the 1980’s, with the Brundtland Commission, laid the foundations for the today’s model of sustainable development.  She opened the conference by placing an emphasis on the role of science in sustainability and the importance of the polar research in finding solutions for the rest of the world.

IGERTS making the rounds at IPY

And on that note students rushed off in all direction to various talks and sessions relating to their particular interests, ranging from polar ocean dynamics to human health and well-being to communicating polar science.  We’ve got a busy week ahead, including poster presentations and talks by Alex Lauder, Julia Bradley-Cook, Laura Levy, Ben Kopec, Rebecca Williams, Lauren Culler and, last but not least, our intrepid leader, Dr. Ross Virginia.
