Environmental Influences On Juvenile Fish Abundances In A River-Dominated Coastal System, Laure Carassou, Brian Dzwonkowski, Frank J. Hernandez, Jr., Sean P. Powers, William M. Graham, Kyeong Park, John Mareska

University Faculty and Staff Publications

We investigated the influence of climatic and environmental factors on variations in juvenile abundances of marine fishes in a river-dominated coastal system of the north-central Gulf of Mexico, where an elevated primary productivity sustains fisheries of high economic importance. Fish were collected monthly with an otter trawl at three stations near Mobile Bay from 1982 to 2007. Fish sizes were used to isolate juvenile stages within the data set, and monthly patterns in juvenile fish abundance and size were then used to identify seasonal peaks for each species. The average numbers of juvenile fish collected during these seasonal peaks in …

Mapping Potential Crp Land And Determining Crp Profitability In Lancaster County, Jamie Pesek

Department of Environmental Studies: Undergraduate Student Theses

Annually 17 tons of soil is lost due to the erosion of agriculture land. A majority of the soil lost is fertile topsoil, which can render the land unproductive. The Conservation Reserve Program (CRP) was enacted to reduce the high erosion rates on agriculture land by giving landowners a monetary incentive to let their land lay idle and allow the soil to regenerate. Although there is awareness of the benefits of CRP, little effort has been put toward delineating CRP eligible land. In this project, Geographical Information Systems were used to map CRP eligible land in Lancaster County, Nebraska based …

Water Quality Trends For Section 319 Priority Watersheds In Northwest Arkansas, 1997-2010, Bryan William Bailey

Graduate Theses and Dissertations

Northwest Arkansas contains two Section 319 Priority Watersheds that the Arkansas Natural Resources Commission (ANRC) has identified as being impacted by point and nonpoint sources of pollution (i.e., phosphorus, nitrogen, and sediment), and the Arkansas Water Resources Center (AWRC) has monitored the water quality at several sites within these watersheds. Water-quality data has been collected over the last decade within the Illinois River Watershed (HUC #11110103) and the Upper White River Basin (Beaver Reservoir HUC# 11010001), each watershed containing three sampling sites. The Illinois River Watershed sites are located on the Illinois River, Osage Creek, and Ballard Creek, and the …

Habitat Use And Abundance Patterns Of Sandhill Cranes In The Central Platte River Valley, Nebraska, 2003–2010, Todd Joseph Buckley

School of Natural Resources: Dissertations, Theses, and Student Research

The Central Platte River Valley (CPRV) in Nebraska is an important spring stopover area for the midcontinent population of sandhill cranes. Alterations to crop rotation and loss habitat in the CPRV pose a risk to the population. Personnel drove designated routes in the CPRV from 2003–2010 to record the presence of cranes in agricultural fields and estimate abundance. I developed and evaluated models to predict habitat use and flock sizes. Alfalfa was predicted to receive the highest use followed by corn, soybeans, winter wheat, grassland, and shrubland. Use of all habitats and flock size increased as field area increased. Flock …

Historical Vegetation Of Central Southwest Oregon, Based On Glo Survey Notes : Final Report To Usdi Bureau Of Land Management, Medford District, O. Eugene Hickman, John A. Christy

Institute for Natural Resources Publications

Historical vegetation at the time of European settlement is of great interest to both the public and land managers, but is poorly documented. One source of data are the earliest land survey records of the General Land Office (GLO). Rectangular township surveys in Southwest Oregon were initiated in the mid 1850’s as settlers began to claim homesteads in the Bear Creek Valley surrounding what is now Medford. We examined GLO land survey field notes and plats (maps) accompanying the surveys, transcribed GLO landscape data into an Access database, and classified the data set into very general vegetation types for mapping. …

Is Lac Anony Reaching Its Tipping Point? A Comparative Case Study Of The Traditional Fishery At The Village Of Antsovela, Corinne Haynes

Independent Study Project (ISP) Collection

Traditional fisheries are globally recognized as an important supplier of food resources. In fact, “small-scale fisheries provide over half the world’s wild-caught seafood” (Shester and Micheli, 2011). All around the southern tip of Madagascar, the traditional fishing industry acts as one of the most common livelihoods. The island nation contributes 120,000,000 tons of aquatic resources to the world supply each year, the majority of which is caught by traditional fishermen found in 1,250 rural villages all around the island. However, 80% of the catch is consumed locally, pinpointing the main goal of these traditional fishermen: to feed their families (RAZANOELISOA, …

Optimizing Spectral Indices And Chemometric Analysis Of Leaf Chemical Properties Using Radiative Transfer Modeling, Jean-Baptiste Féret, Christophe François, Anatoly A. Gitelson, Gregory P. Asner, Karen M. Barry, Cinzia Panigada, Stéphane Jacquemoud

School of Natural Resources: Faculty Publications

We used synthetic reflectance spectra generated by a radiative transfer model, PROSPECT-5, to develop statistical relationships between leaf optical and chemical properties, which were applied to experimental data without any readjustment. Four distinct synthetic datasets were tested: two unrealistic, uniform distributions and two normal distributions based on statistical properties drawn from a comprehensive experimental database. Two methods used in remote sensing to retrieve vegetation chemical composition, spectral indices and Partial Least Squares (PLS) regression, were trained both on the synthetic and experimental datasets, and validated against observations. Results are compared to a cross-validation process and model inversion applied to the …

Tracking Large Carnivore Dispersal Using Isotopic Clues In Claws: An Application To Cougars Across The Great Plains, Viviane Hénaux, Larkin A. Powell, Keith A. Hobson, Clayton Kent Nielsen, Michelle A. Larue

School of Natural Resources: Faculty Publications

1. Cougar (Puma concolor) populations, like other large carnivores, have increased during recent decades and may be recolonizing their former ranges in Midwestern North America. The dispersal routes taken by these animals from established populations are unknown and insight into these movements would facilitate their conservation and management.

2. We inferred the origin and migration route of four dispersing cougars using stable hydrogen (δD) and carbon (δ¹³C) isotope values along one of their claws. We compared isotopic variations within claws to regional and large-scale isoscapes of δD and δ¹³C values in prey species. Using …

El Manejo De Recursos Marinos En El Área De Yandub-Narganá, Kuna Yala: Estrategias, Objetivos Y Dificultades, Hannah Marie Colton

Independent Study Project (ISP) Collection

The Kuna people are dependent on marine resources for sustenance, income, and protection. Coral reefs, mangrove stands, and sea grass beds provide food and shelter for marine animals which fuel the bodies and economy of Kuna communities. However, practices such as traditional coral mining and overfishing threaten the future of these resources. Recent scientific surveys have recommended the establishment of several larger Marine Protected Areas in Kuna Yala, in order to conserve habitats and allow the gradual repopulation of marine animals (Guzmán et al, 2003). The Kuna General Congress, the autonomous government of the Comarca of Kuna Yala, has the …

Portraits Of The Land: Environmentalism And Contemporary Art In Mongolia, Sarah Morgan

Independent Study Project (ISP) Collection

Environmental concerns are globally relevant, but in Mongolia they hold special importance. Not only does Mongolia contain an unusual amount of pristine wilderness, but Mongolian history and culture are also deeply rooted in a close bond with the land. Now, increased development and globalization are placing new pressures on environmental systems. In response to these pressures, Mongolians artists are joining a national (and global) conversation about the interactions between art, environment, cultural heritage, and activism.

This study explores the sources of inspiration and motivation for these artists. Through this research, I hope to bring to light the role of the …

El Perro De Monte De Sechura: Su Relación Con El Bosque Seco Tropical Y La Gente De La Región Central De Manabí, Julian O. Buffam

Independent Study Project (ISP) Collection

The Cerro Hojas-Jaboncillo, located in Central Manabí, Ecuador, is a Patrimonial site that, in addition to containing the ruins of an ancient culture, is home to a species of mammal endemic to the tumbesian eco-region. Currently listed by the ‘LibroRojo de los mamíferos del Ecuador’ as vulnerable, the Sechuran Fox (Lycalopexsechurae) is a nocturnal and solitary animal, of a medium size, that is rarely seen due to its elusive behavior. This species is the focus of this investigation, which seeks to gain an understanding of the plants and animals that the Sechuran Fox requires for food, the home …

Independent Study Project (ISP) Collection

Through the recent years, the Cuenca-Molleturo-Naranjal highway that cuts through the Cajas national park has been the object of much environmental research. In particular, the effects of the highway on the territorial distribution of the local avifauna—that includes many endemic and endangered species—has been a very important subject of study for the conservationists and the park managers. The following study is supplementary to the work of the University of Azuay and the University of Stoneybrook in New York. Here, we analyze how the highway may influence the sex ratios of one of the most commonly found specie—Phrygilus unicolor. Using observations …

A Study Of Sponge Aquaculture In Jambiani: Is Shallow Farming Feasible?, Sarah Friday

Independent Study Project (ISP) Collection

In the village of Jambiani, Unguja, a Swiss NGO called Marine Cultures has established an experimental sponge farming initiative to improve local employment and support economic development. Currently, the main farming site is only accessible through SCUBA diving. This is consistent with experimental farm sites in other oceanic regions, as most are located in depths of at least five meters with sponges suspended vertically to maximize water flow exposure. Farms located in shallower water may not be conducive to sponge growth due to highly variable environmental conditions; however, no conclusive research has been conducted on this matter (Duckworth 2009). Nonetheless, …

Seaweed Farmer Education: Is It Enough To Sustain The Industry? Analyzing The Status Of Stakeholder Investment In Muungoni And Jambiani, Unguja, Erika Davis

Independent Study Project (ISP) Collection

Since Filipino researchers arrived in Zanzibar to determine the potential for cultivation of seaweed more than 20 years ago, the islands' coastal communities have relied on the resource as a main or alternative source of income. When the companies started investing at the industry’s onset, trained personnel offered farmers' education on proper farming techniques for Spinosum (Eucheuma denticulatum) and Cottonii (Kappaphycus spp.) by establishing demonstrative (demo) farms and holding seminars. Today, informal training involves experienced farmers teaching the newcomers their techniques. While demo farms remain in some villages, companies offer no extension services based on the belief that the farmers …

In The Realm Of Supay: The Stories Of The Miners, Graham Sutherland

Independent Study Project (ISP) Collection

Ah, El Cerro Rico. She’s beautiful, no? Looming over Potosí with her red-tinted earth. But her real beauty is hidden within. Her body filled with veins of silver, the very silver that shimmered in the eyes of the Spanish empire and made Potosí one of the largest cities in the world. Oh, and the tin, the tin that helped Simon Patiño own mansions on 3 continents, living in villas in the United States and France while the ones here in Bolivia only collected dust. Mineral wealth you wouldn’t believe. They say that the Cerro Rico has twelve polleras of riches, …

Above The Mukpa: The Shifting Ground Of Khumbu's Sacred Geography, Noah Brautigam

Independent Study Project (ISP) Collection

The Himalayan region is suffering from global warming,2 and the effects are felt at all scales, from the local to the global. Himalayan glaciers feed ten major Asian rivers, and 1.3 billion people in southern and southeast Asia reside in those river basins (Eriksson, et al. 2009:1). Global warming is melting these glaciers at a rapid rate, with retreat ranging from 10 to 60 meters per year on average, and many smaller glaciers already disappearing (Mool, Bajracharya and Shrestha 2008:1). This research is a study of local perceptions of global warming and glacial melt among the Sherpas of Khumbu, Nepal. …

Mapping Agroforestry Design In Project Tipitamba: The Influence Of Spacing On Tree Growth, Joseph Lee

Independent Study Project (ISP) Collection

Agriculturalists in Brasil’s Zona Bragantina are balancing short term social and economic goals with the long term productivity of their agroecosystems. While these goals often times are seen as conflicting, the implementation of agroforestry systems through EMBRAPA’s Projeto Tipitamba has provided an opportunity for farmers in the region to intercrop quick growing, marketable, non-timber forest products with highly valued lumber species all on the same area of land. As Projeto Tipitamba also provides the associated farmers with access to a bush-chopper, it also allows for farmers to stop swidden, slash-and-burn, agriculture and convert to chop-and-mulch land preparation. As a result, …

Future Participation In The Conservation Reserve Program In North Dakota, Lorilie M. Atkinson, Rebecca J. Romsdahl, Michael J. Hill

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The purpose of this study was to gauge the impact of agriculture and energy policies on conservation practices through a survey of conservation reserve program (CRP) contract holders in a selected Prairie Pothole Region of North Dakota-Burleigh, Kidder, and Stutsman Counties. The survey results showed that 48% of respondents are considering returning CRP acres to annual crop production once the contract expires. The largest influence on post-CRP land use was the market prices for production of annual crops. Respondents also identified lack of knowledge of conservation programs as a large hurdle to participation. This may indicate a need for improved …

Review Of Grass: In Search Of Human Habitat. By Joe C. Truett. Foreword By Harry W. Greene., Mary Ann Vinton

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Much of the book is devoted to discussing the heavy human dependence on grasslands and whether this relationship can be maintained in company with grassland conservation. Can humans continue to use grasslands for food, fiber, and newer uses like biofuels and carbon banking while still sustaining the ecosystem? Many of us in academic ecology struggle with resolving perceived conflicts between conservation and human grassland use. In many cases, a "win-win" scenario exists in which, for example, the proper use of livestock grazing is perfectly compatible with a healthy grassland ecosystem. In other cases, such as conserving prairie dog populations, tensions …

Student Publications

In the fall of 2011, the Environmental Studies capstone class led by Professor Rutherford Platt was asked to write Gettysburg College’s first Sustainability Plan. The goal of the plan was to develop specific sustainable practices for the campus that were related to the three pillars of sustainability: economic, social, and environmental, and how integrating diligent sustainable practices into each of these respected pillars will result in a more conscious campus, community, and future. In 2010, Gettysburg College turned to the Sustainability Tracking Assessment and Rating System (STARS) to quantify the institution’s sustainability efforts, providing a self-check mechanism to encourage sustainability …

What Is The Value Of A Sea Turtle?: A Case Study Of The Conservation Ethics Of Sea Turtle Fishermen In The Caribbean Coast Of Nicaragua, Alicia Conte

Independent Study Project (ISP) Collection

The sea turtle populations on the Caribbean Coast of Nicaragua have dramatically decreased as a result of human use and consumption. All species of sea turtles are endangered and at risk of extinction. This is an environmental issue because if sea turtles go extinct, many other plants and animals in marine ecosystems will be negatively impacted by this loss, and the environment will be drastically altered. This is also problematic for locals who depend on this resource for food and as a source of income. Conservation efforts have been initiated by an international NGO, the Wildlife Conservation Society (WCS); however, …

The Role Of Information In Enabling Community Response To Mining Threats In Palmares Ii, Christine Gerbode

Independent Study Project (ISP) Collection

The case of Palmares II is examined to understand the role that knowledge (or misinformation/lack thereof) of specific geologic interests and rights of surface communities plays in enabling those communities to respond to the possibility of mining on their land. Palmares II is an MST settlement located near the Carajás mining complex in southern Pará. Currently, a number of companies are authorized or requesting permission to conduct research for mineral ores such as gold, copper, manganese, diamond, and nickel within the borders of the settlement; it is therefore potentially possible that this community will face mining interest on their land …
