Students and Faculty Form NIU Geography Club and Revitalize GTU Honor Society Chapter

In an effort to better connect students and faculty both inside and outside the classroom, geography students have urged the formation of an NIU Geography Club. The club has already met several times this fall semester and has planned off-campus events and outreach activities to engage students and bolster membership. Current officers of the NIU Geography Club are: Joe Sepulveda (President), Andrew Bogda (Vice President), Rachael Poll (Secretary), Adam Rasmussen (Treasurer) and Trevor Edmonson (Public Relations Officer).

In addition to forming the NIU Geography Club, the department is revitalizing its Iota Gamma Chapter of Gamma Theta Upsilon (GTU) which was established in 1965 but has been relatively dormant since the mid-1980s. GTU is an international academic honor society in geography that was founded in 1928. GTU's mission is to bring together university students who share a background and interest in geography and, more generally, support geographic knowledge and awareness.

We invite you to become active participants in these groups. Membership information is below.



Membership in the NIU Geography Club
Everyone is welcome to join who is a student at NIU. There is no cost for membership at this time. Anyone who is interested should join the club's facebook group (NIU Geography Club) or contact Dr. David Goldblum for additional information.

Membership in Gamma Theta Upsilon
Membership in GTU is a distinction that could, and should, be noted on a resume. Membership also qualifies you to apply for a variety of scholarships and offers the opportunity to hone your leadership skills through NIU's Iota Gamma Chapter activities and activities of the Geography Club.

NIU Geography Students Present Research, Win Award at ILGISA Conference

NIU Geography seniors, Michaela Friedrichova and John Trishcan presented their research at the Illinois GIS Association (ILGISA) fall conference held at NIU's Naperville campus on October 6.

The title of Michaela's presentation was Creating a Customized Google Map: A Case Study of Tai Toponyms in Southern China and Thailand. She used ArcMap2GMap to convert shapefiles of Tai toponyms to a Google Map format with built-in JavaScript, which can be fully customized to show multiple visible layers in Tai and Chinese fonts. The custom Google Map--available at http://www.niu.edu/landform/taiplacenames.html--can be used to visualize and explore the spatial distribution of Tai toponyms and their relationship with the physical environment.

John's presentation concerned Estimating the Volume of Excavation of Martian Valley Networks. He used Black Top Hat transformation, an image processing technique, to extract valley depth from Mars Orbiter Laser Altimeter (MOLA) data and estimated the volume of selected valley networks on Mars. Valley networks are river-like features on Mars that may contain important information about past climate and water on Mars. Estimating their volume can help determine the amount water needed to form them and the rate of erosion.

This was the first professional presentation for both Michaela and John and they learned a lot from this experience. They both have been working with Dr. Wei Luo since this summer.

Melissa Burlingame, an NIU Geography graduate student, won ILGISA's People's Choice Award for her the poster she presented, entitled, Evaluating Land Cover Changes Over Time.

Melissa's research examines how county-wide assessment of natural resource management policies may be improved with access to readily-available data and easily-interpretable measures. Kane County, Illinois was chosen as the study area due, in part, to its rapid urban development over the past decade. Publicly available land cover data from the US Department of Agriculture (National Agriculture Statistics Service –NASS) were used together with FRAGSTATS, a landscape ecology freeware package, to examine land cover changes and evaluate the degree to which these analyses may inform conservation policy decisions. Melissa's preliminary findings suggest that Kane County has made progress toward conserving forest, wetland, and pasture land over the study period.

Congratulations NIU Geography students on your impressive work!

NIU Geography Soil Judging Team Advances to National Competition

Observation is often the first step toward understanding in science. For student members of NIU's Soil Judging Team, observation is also the key to determining the nature of a soil, how it formed, what types of vegetation it can support, how well it drains, and its ability to safely bear homes, buildings, and roads.

For the third year in a row, a team of students from Northern Illinois University competed in soil judging against teams from universities in Illinois, Indiana, Wisconsin, and Michigan and, for the second year in a row, NIU's soil judging team demonstrated their outstanding skills in observation and interpretation. NIU's team of TJ Abell, Clint Bailey, Aaron Browning, Paul Gruca, Amber Singer, and Norman Yackle placed second overall in the Region 3 Soil Judging contest held in early October near West Lafayette, Indiana. Two of the team's members medaled in the individual competition, with Aaron Browning placing second and Clint Bailey placing fifth. This year's Region 3 Collegiate Soils Contest was hosted by Purdue University and the Indiana Association of Professional Soil Classifiers. By virtue of its second place score, NIU's Soil Judging Team is eligible to compete in the 50th Anniversary National Collegiate Soils Competition to be held in Lubbock, Texas in March 2010. Congratulations!

NIU Graduate Student Research: Systematic Evaluation of Prairie Planting Regimes

Conservation ecologists over the past several decades have sought to better understand the factors that promote biodiversity in and the resilience of ecological systems. In order to forward this effort, Brian Glaves, an NIU Geography graduate student, engaged in an experiment to identify the optimal amount or density of native seed required to produce a successful prairie planting.

Rough Blazing Star (Liatris aspera) blooming within Nachusa Grasslands

Brian's project was situated within the idyllic 3,000 acre Nachusa Grasslands, a conservation area in north central Illinois. The project was an extension of a previous experiment carried out in 2006 by Bill Kleiman who, along with numerous volunteers, manages the grasslands. For this earlier experiment, Kleiman applied a dry mesic mix of native Nachusa Grasslands seeds to a smaller region of the conservation area known as Clear Creek Knolls. This seed density experiment established a 3 x 5 systematic random quadrant design in which one of four categories of seed density treatments (10, 30, 50 and 70 pounds per acre) were applied or dispersed. The seeding was replicated three times with each treatment assigned randomly to a (9m x 9m) quadrant in order to control for local variation. The systematic random quadrant design provided a standard method for examining and recording the performance of each treatment relative to each other and a control group.

In the summer months of June, July and August 2008, Brian began a systematic recording of floristic data from the 2006 planting. Specifically, Brian measured species richness, species density, percent flora cover and species height. A variety of indices such as the Shannon-Weiner diversity index (i.e., frequency and evenness of each species within the community), Simpson's dominance index (i.e., a measure of the dominance of any one species) and a Floristic Quality Index were then used to characterize the data collected in the field and examine the relative performance of each seed density regime.

Brian's results showed no statistically significant difference between the various indices across the four categories of seed density treatments, although some general trends were apparent. For example, lower seed density treatments tended to exhibit higher Simpson's (dominance) values (Figure on left), while greater densities exhibited higher Shannon-Weiner (diversity) values (Figure on right). The Forensic Quality Indices also suggest that treatments were significantly different from the control (One-way ANOVA, p=0.05) but not to each other. Further, the total plant cover varied over the study periods such that plant cover as observed in June was statistically different from the plant cover observed in July and August. This was in part due to the greater abundance of exotic species earlier in the season. Lastly, the data suggest that individual species tended to be better represented after applying the 50 pounds per acre seed density treatment. In fact, the statistical analyses suggest that the 50 pounds per acre seed density treatment (rather than the more resource intensive 70 pound treatment) was the best option for Nachusa Grasslands prairie restoration while the 30 pounds per acre treatment was acceptable.

So why is this research important? Most research to date on seed density applications for prairie restoration has been rather informal in its analysis of planting regimes. Brian's research puts forward a more scientifically rigorous strategy for evaluating successful prairie planting. In particular, what this experiment showed is that prairie restoration seeding practices can be defined within rather clear ranges, in this case 30 to 50 pounds of seed per acre.

Geographic Communication--Appreciating NIU's Cartography Lab

What distinguishes geography from other sciences is its attention to the production, interpretation and communication of geographic information. For geographers, maps are oftentimes the common semantic, the objects through which they communicate with each other and the broader community.

The NIU Department of Geography Cartography Lab is especially interested in high quality cartographic communication. Established in 1965, the Cartography Lab has an impressive history of producing elegant and functional maps for research, government and not-for-profit communities. The cartographic creativity of Leonard Walther and Jodi Heitkamp--the lab's full time personnel--is perhaps best exemplified in their large-scale maps depicting the research of NIU Geography faculty. These eye-catching posters adorn the walls of NIU Geography's Davis Hall, and encourage passersby to read the latest scientific findings.

Collaborations with off-campus entities have also provided opportunities for the Cartography Lab to distribute spatial knowledge and forward geographic literacy. One example is a map produced for the The Northern Illinois Food Bank which was used to inform the strategic placement of distribution centers and food pantries. More recently, the Cartography Lab allied with the Illinois Department of Transportation (IDOT) to develop a series of bicycle maps. Over 800,000 of these maps have been distributed by IDOT over the past decade, making it a hit among Illinois' outdoor enthusiasts. The Kane County Bicycle Map (Figure on right), for example, is free to the public and features existing and proposed bicycle and pedestrian trails, bicycle level of service ratings for selected roadways, points of interest and major destinations, mile markers, and information on trail etiquette, sharing the trail (and the road) and bicycle safety. This map has been especially popular with the public and has received numerous awards including the Soles and Spokes Award for Excellence from the Chicago Area Transportation Study and an Honorable Mention in the planning category from the Illinois Chapter of the American Planning Association. The League of Illinois Bicyclists has also commissioned the Cartography Lab to produce similar multi-modal maps for the City of Aurora.

The Cartography Lab also shares its cartographic knowledge via teaching and other pedagogical activities. One popular independent study course (GEOG 467) centers around the design and production of a cartographic product such as a large-scale printed map, folded brochure, or small booklet. Students are encouraged to work with an outside organization who may want a map to fulfill a particular objective. In this way, students learn to work with real-world clients by co-designing geographic products that meet their needs. This independent study is popular not only because of its practical application but also because of its personalized instruction. The maximum course load of four means students are able to work closely with Cartography Lab staff on a regular basis, thereby acquiring valuable experience in navigating the rather complicated design and translation tools available in today's advanced cartographic software.
