Dye Tracing Through The Vadose Zone Above Wind Cave, Custer County, South Dakota, James Nepstad

Sinkhole Conference 2015

During the 1990s, in an attempt to better understand threats posed by surface developments overlying the cave, National Park Service staff at Wind Cave National Park in Custer County, South Dakota carried out a series of dye traces through portions of the vadose zone overlying the cave. Wind Cave is located within the 100m-thick Madison formation (limestone and dolomite), which in most locations is capped by varying thicknesses of the basal units of the Minnelusa formation (intermingled beds of sandstone, limestone, and shale). A variety of cave locations with dripping or pooled water were monitored for up to five years …

Creation Of A Map Of Paleozoic Bedrock Springsheds In Southeast Minnesota, Jeffrey A. Green, E. Calvin Alexander Jr.

Sinkhole Conference 2015

Springs are groundwater discharge points that serve as vital coldwater sources for streams in southeast Minnesota. The springs generally emanate from Paleozoic carbonate and siliciclastic bedrock aquifers. Use of systematic dye tracing began in the 1970s and continues through the present as a standard method for investigating karst hydrology and to map springsheds,. The work was accelerated in 2007 because of increased funding from the State of Minnesota’s Environment and Natural Resources Trust Fund. A compilation springshed map of dye traces conducted over the last several decades has been assembled for the region. In southeast Minnesota, the springs are the …

Mitigating The Risk Of Extreme Water Scarcity And Dependency: The Case Of Jordan, Joep F. Schyns, Arwa Hamaideh, Arjen Y. Hoekstra, Mesfin Mekonnen, Marlou Schyns

Daugherty Water for Food Global Institute: Faculty Publications

Jordan faces great internal water scarcity and pollution, conflict over trans-boundary waters, and strong dependency on external water resources through trade. This paper analyzes these issues and subsequently reviews options to reduce the risk of extreme water scarcity and dependency. Based on estimates of water footprint, water availability, and virtual water trade, we find that groundwater consumption is nearly double the groundwater availability, water pollution aggravates blue water scarcity, and Jordan’s external virtual water import dependency is 86%. The review of response options yields 10 ingredients for a strategy for Jordan to mitigate the risks of extreme water scarcity and …

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …

Economic Valuation Of Marine And Coastal Ecosystems: Is It Currently Fit For Purpose?, Nick Hanley, Stephen Hynes, David Patterson, Niels Jobstvogt

Journal of Ocean and Coastal Economics

In this paper, we consider whether the current “state of the art” of environmental valuation is suitable for producing policy-relevant estimates of the benefits or costs of changes in marine and coastal ecosystems. We review recent changes in European legislation which has meant an increasing demand for economic valuation from the policy and regulatory community. The next section considers, at a more conceptual level, whether the economic “toolbox” and scientific evidence is up to the task of meeting the demand for more evidence-based policy. Finally, three case studies are used to explore the nature of the valuation task and review …

Fluctuating Fire Regimes And Their Historical Effects On Genetic Variation In An Endangered Shrubland Specialist, Hernan Vázquez-Miranda, Kelly R. Barr, C. Craig Farquhar, Robert M. Zink

School of Natural Resources: Faculty Publications

The Pleistocene was characterized by worldwide shifts in community compositions. Some of these shifts were a result of changes in fire regimes, which influenced the distribution of species belonging to fire-dependent communities. We studied an endangered juniper–oak shrubland specialist, the black-capped vireo (Vireo atricapilla). This species was locally extirpated in parts of Texas and Oklahoma by the end of the 1980s as a result of habitat change and loss, predation, brood parasitism, and anthropogenic fire suppression. We sequenced multiple nuclear loci and used coalescence methods to obtain a deeper understanding of historical population trends than that typically available …

Working With Locals To Restore Biodiversity To A Rubber Dominated Landscape, Francis Commercon

Independent Study Project (ISP) Collection

Xishuangbanna, in Yunnan,China, contains the country’s highest concentration of biodiversity. Since the 1980s,rubber plantations have replaced a significant portion of the prefecture’s lowland Seasonal Tropical Rainforest, leading to wildlife habitat loss and other environmental issues.Monoculture farming practices also leave farmers economically vulnerable to market fluctuations. To learn the best solutions for increasing ecosystem services and income stability in rubber-dominated areas, the World Agroforestry Center (ICRAF) project Green Rubber engages smallholders directly in establishing and maintaining scientifically rigorous intercropping experiments in their villages.

Using Man’e village and the Green Rubber project as a case study, I asked to what degree and …

Los Guardianes De Yaoska De Rancho Grande: Ocho Pasos Para Detener Una Empresa Minera Transnacional, Joshua Marcus

Independent Study Project (ISP) Collection

El 11 de octubre de 2015, Monseñor Rolando Álvarez, Obispo de Matagalpa, recibió una llamada telefónica que cambiaría el rostro de Nicaragua. Fue un domingo, y él dirigía la misa en la Catedral de San Pedro radiantemente blanca. Pero la llamada no fue al contestador. Daniel Ortega y Rosarillo Murillo estaban al teléfono, y querían hablar con él. El gobierno había decidido negar el permiso de explotación al proyecto minero de oro Pavón Rancho Grande en Matagalpa. Un día después, se publicó la noticia. Murillo, la vocera gubernamental, anunció que: “La conclusión de todos los expertos ambientales es que el …

Patagonia Con Poder: El Éxito De La Oposición Frente El Proyecto Hidroaysén, Nathaniel Korn

Independent Study Project (ISP) Collection

This investigation analyzes the movement in opposition to the HidroAysén project in Southern Chile that is often referred to as and uses the slogan “Patagonia Sin Represas” (Patagonia Without Dams). The investigation is framed through collective action theory, the study of what incentives and other factors create the conditions for mobilization and group action. In the context of social movements it is usually argued that there needs to be a better cost-benefit scenario for each actor to be involved than there is to not be involved in the movement. Immediately following return of democracy to Chile in the 1990’s social …

An Avian Biological Gradient Across Tropical Dry Lowland Local Habitats At Playa Venao, Los Santos Province, Panama, Abigail Thomas

Independent Study Project (ISP) Collection

There are a myriad of forest types within Panama, varying by elevation, precipitation and other abiotic factors, which hosts a wide variety of native and migratory species in uniquely-structured avian communities. Panama has been well assessed for presence and distribution of its 987 collective avian species (Angehr, 2014). However most studies in Panama have been broad in scope, overlooking the highly specified habitats that are uniquely structured to host a certain range of avifauna communities. The distinctions in community structure of avifauna along a coastal to inland gradient were assessed among three specialized habitats: the Central Pacific coast, partially deforested …

Comparative Study Of Terrestrial Arthropod Diversity In Primary And Re-Planted Pine Forest In A Community Forest At Andasibe, Madagascar, Tyler George, Mira Kelly-Fair, Andrea Wade

Independent Study Project (ISP) Collection

This study is a comparison of tree and terrestrial arthropod diversity along native andre-planted pine transects.Transects were laid in a primary and re-planted pine forest in Andasibe Community Forest Park. Data was collected over six days, taking measurements of trees, inspecting and collecting specimens from pitfall traps once a day. Terrestrial arthropods were identified to morphospecies and measures of diversity were calculated. To understand the health of the trees, information was collected that included trees diameter at breast height, canopy cover and soil cover. Terrestrial arthropod communities and diversity were found to be significantly different in the native and replanted …

An Analysis Of Biodiversity, Sustainability, And Ecotourism In The Vo.I.M.Ma Community Managed Forest, Andasibe, Madagascar, Catherine Knowlton, Charlotte Walton

Independent Study Project (ISP) Collection

The concept of eco-tourism as a culturally sensitive, ecologically beneficial alternative to traditional vacations is a fairly new idea. While on the surface it seems positive for everyone involved, there are complexities in the relationships between all parties. This study explores the ties between the community forest, the tourists, and biodiversity (specifically endemic lemur populations) in the VO.I.M.MA Community Managed Forest. This study found that the community forest model is sustainable, based on the criteria of protecting biodiversity and satisfying customers. To truly promote a sustainable business model in the future (ecologically as well as economically), the center could improve …

Frog Diversity And Population Trends In Andasibe, Madagascar, Ryan Herman Herman, Alexandra Ulin

Independent Study Project (ISP) Collection

Facing immediate threats such as habitat loss, emerging infectious diseases, and climate change, the frog populations of the Madagascar rainforest, one of the richest amphibian diversity hotspots in the world, are an important focus for monitoring programs. This study focused on assessing the general diversity, key species population trends, and monitoring effectiveness of the Analamazaotra Forest Station’s amphibian community, a population of over forty species within Andasibe, Madagascar. Building on a long-term monitoring program that began in 2012, visual encounter surveys were conducted over a two-week period in November 2015 along the edge and within the interior of the forest …

Impact Of Invasive Species Datura Arborea On Plant Species Richness In The West Usambara Mountains, Megan Foley

Independent Study Project (ISP) Collection

Invasive species have the potential to alter the evolutionary trajectory of ecosystems and native species; however, our understanding of the community level effects of invasive plants remains poor. The Eastern Arc Mountain Chain is listed as one of the top 25 biodiversity “hotspots” of the world, yet also as one of the 17 most threatened tropical forest ecosystems worldwide. The primary threat to biodiversity in the EAM is accredited to human encroachment; however, the impact of invasive species in the EAM, and across Tanzania, remains poorly understood. National biodiversity and resource management policy do not directly address invasive species, and …

Characteristics Of Geoffroy’S Tamarin (Saguinus Geoffroyi) Population, Demographics, And Territory Sizes In Urban Park Habitat (Parque Natural Metropolitano, Panama City, Panama), Caitlin Mcnaughton

Independent Study Project (ISP) Collection

Metropolitan parks are an important refuge for wildlife in developed areas. In the tropics, land conversion threatens rainforest habitat that holds some of the highest levels of biodiversity in the world. This study aims to investigate the characteristics of Geoffroy’s tamarin (Saguinus geoffroyi) population, demographics, and territory size in a highly urbanized forest habitat (Parque Natural Metropolitano (PNM), Panama City, Republic of Panamá). Studies of animal response to modified habitats are important as development continues worldwide. S. geoffroyi is an ideal species to study for this purpose due to the species’ tolerance to habitat disturbance. This particular park is …

Water Quality In The Río Pastaza Watershed A Comparative Study Of Ríos Topo, Zuñag, And Pastaza And The Impact Of The Topo Hydroelectric Project Using Macroinvertebrates As Bioindicators, Jesse Vega-Perkins

Independent Study Project (ISP) Collection

Ríos Zuñag, Pastaza, and Topo flow through one of the rainiest and water-rich places in Ecuador. Río Zuñag is a relatively small, pristine montane river and Río Pastaza is a relatively large, contaminated river that receives the untreated wastewater of many communities. Río Topo’s unique watershed and gradient allow it to be home to many plants that have adapted to its unique environment, including the hyperendemic liverwort Myriocolea irrorata. However, in recent years, all of the water of Río Topo has been sold by the state of Ecuador to be developed for hydroelectric projects (HEP). The first of these …
