Temperature- Dependent Sex Determination (TSD) of Painted Turtles, Chrysemys picta

The project that I have been undertaking during the spring 2014 semester is based on Professor Scott Boback’s research on Painted turtle nesting at a man-made pond located in Cumberland County, Pennsylvania. The specific study site is located at the Hunstsdale Fish Hatchery in Huntsdale, Pennsylvania. The sex of an embryo is temperature-dependent and has a spatially relevant factor as to where nests are located. Nest sites and attempted sites are constrained between a railroad and pond, creating a highly spatially restricted data sample. The data will be geographically and temporally organized and then displayed in relation to temperature readings from a recording device (ibuttons, Embedded Data Systems). There was a set of sixteen active nest sites, which could be correlated to ibutton data based on date and … Read entire article »

Dickinson Running Routes with Difficulty – Anne Dyroff

The Dickinson College cross-country team has created a large number of running routes in the Carlisle area. Each running route is communicated to new members of the team via word-of-mouth. The problems addressed with this project are the difficulty in learning all of the available running routes through Carlisle, and the lack of knowledge about each route. In order to make the created running routes more accessible, a detailed map of each route has been created. Each map has been rendered to display the difficulty of each section of the route. The difficulty rating is based upon slope gradient and hill length. A hard copy of each map is … Read entire article »

3-D Map of Vatnsskarð Pillow Ridge Quarry, Iceland

3-D Map of Vatnsskarð Pillow Ridge Quarry, Iceland

A quarry at Vatnsskarð, which is part of the Krisuvik fissure system in southwestern Iceland, provides exceptional exposures of the stratigraphy and insights into the formation processes of a glaciovolcanic, pillow-dominated tindar. The active part of the quarry is ~0.5 km wide and 0.7 km long, while the overall width of the ridge at this location is ~1.2 km. This … Read entire article »

How Diverse are our Trees? An Analysis of the Trees on Dickinson College’s Campus

Urban forests, much like those of college campuses can be unbalanced in species diversity, and richness, which can lead to devastation. By determining these factors and applying a standard guide, the health of the forest is able to be established, and in doing so creating a better way to manage the trees. The standard guide used is the 10-20-30 rule, which says that no more than 10% of the trees should be of the same species, no more than 20% of the trees should be from the same genus, and no more than 30% should be from the same family. The 10-20-30 rule is often used as a standard to determine if the species diversity … Read entire article »

The spatial distribution of weathering on Basse-Terre Island, Guadeloupe

The spatial distribution of weathering on Basse-Terre Island, Guadeloupe

The aim of this study is to investigate the spatial relationship between chemical weathering on Basse-Terre and two spatially varying factors; precipitation and bedrock age. Basse-Terre, the large western island of Guadeloupe archipelago, and is part of the Lesser Antilles volcanic arc in the eastern Caribbean. The island is comprised entirely of andesite bedrock that decreases in age to the … Read entire article »

Unmapped Trails in Michaux State Forest

Unmapped Trails in Michaux State Forest

Michaux State Forest provides countless trails for a wide range of outdoor activities. The Pennsylvania Department of Conservation and Natural Resources (DCNR) has worked hard to maintain these trails and provide sufficient information about them so that they are easily accessible and remain safe for public use. Although there are already extensive trails for use, many adventure-seekers have taken it … Read entire article »

Prioritizing Stream Remediation Efforts in Pennsylvania’s Michaux State Forest

Bryan (Poster Final Draft): This project addresses the question of how to most effectively allocate stream remediation measures within the Michaux State Forest. The Michaux State Forest has a wide variety of streams and water trails within its boundaries. The park service realizes that a number of these streams are in need of varying degrees of remediation; however, the park service doesn’t have the resources to address each individual stream in need. As a result, it becomes necessary to prioritize these streams in such a way that the park service may remediate them in the most effective way possible, considering the resources they have at their disposal. In order to do accomplish this objective, eight testing sites … Read entire article »

Effective Site Management Using GIS: Using Sophisticated GPS Equipment to Map ALLARMs Riparian Buffer

Effective Site Management Using GIS: Using Sophisticated GPS Equipment to Map ALLARMs Riparian Buffer

Starting in 2012, the Alliance for Aquatic Resource Monitoring (ALLARM), with help from a grant from the Dickinson College Farm, began working to vegetate and manage its own riparian buffer. A riparian buffer is a vegetated area next to a stream or body of water. Usually comprised of native species, riparian buffers promote good overall stream health by stabilizing stream … Read entire article »

Catchment Basin Areas in Baxter State Park

Catchment Basin Areas in Baxter State Park

Understanding upstream catchment basin areas of culverts add to the analysis of both the quality of infrastructure as well as the stream habitat. Mr. Richard Morrill is the Resource Manager of Baxter State Park in Maine and is interested in understanding how the area of the upstream catchment basin of culverts may impact fish habitat. The culverts that were given … Read entire article »

Historical Barns: A Study on the Importance of Spatially Analyzing History

Historical Barns: A Study on the Importance of Spatially Analyzing History

Abstract: I chose to collect location data as part of a case study to show why it is important to analyze history through space as an asset to what is primarily studied in literature, documents, and artifacts. By utilizing place-based learning in history, a whole new dimension to history can be explored, and it is equally important to capture this … Read entire article »

A Modern Analog to Map the Past: Lake Vegetation of the Bolivian Altiplano

A Modern Analog to Map the Past: Lake Vegetation of the Bolivian Altiplano

Modern Lakes Poopó and Titicaca offer differing shore habitats; however, we can use these different modern environments to help understand ancient vegetative environments of the Bolivian Altiplano. During the summer of 2013, a team of American and Bolivian researchers from the Taraco Archaeological Project collected plant samples and GIS data to gain a better understanding of these lake basins in … Read entire article »

Factors Affecting the Spatial Distribution of the Hemlock Woolly Adelgid

The hemlock woolly adelgid (Adelges tsugae) is an invasive aphid-like insect that is damaging the native hemlock trees on the East coast of the United States. In their study comparing valley and ridge-top hemlock stands, Hautaniemi and Link found that adelgids were significantly more abundant on ridge-top hemlock stands than in valley hemlock stands. Hautaniemi and Link also found that indicators of tree health (crown density and new growth) were significantly higher in valley hemlock stands than they were in ridge-top hemlock stands. What could be causing the hemlock trees to be in greater health in valleys and why are there more adelgids on ridge-tops? The purpose of this study is to analyze the data … Read entire article »
