Long-Term Disturbance Histories Of Managed And Natural Mixed-Hardwood Forests Of Central Indiana, Robert Charles Morrissey

Open Access Dissertations

Over the course of the last century, we have observed changes in forest composition and structure related to changes in disturbance regimes. Reduced frequency and severity of disturbance events has allowed for the ingrowth of shade-tolerant, mesophytic species into forest understories; the result is shifting species compositions and changes in forest structure. In some cases, the loss of masting species, such as oak (Quercus spp.) and hickory (Carya spp.), may also accompany a shift in forest function and further accommodate other species shifts among mammal, insect, and bird populations. Management efforts have been suggested as a possible means …

Traditional Boat Building: An Intersection Of Zanzibar’S Culture And Environment, Eric Levenson

Independent Study Project (ISP) Collection

This study examined traditional boat building on Uzi Island as a manifestation of Zanzibar’s relationship of environment and culture. Information was gathered about traditional boat building practices, the resource use and management pertaining to boats, the cultural reliance on boats, and local views on environment and conservation. This information showed that the people of Uzi Island were dependent on the use of traditional boats to maintain their livelihood, however the tree types used for boat building are being over-harvested. This tension of culture and environment exposed the need for conservation of Zanzibar’s natural resources in a manner that does not …

The ‘Boonies: Effects Of Habitat On The Behavior Of Papio Anubis Outside Of Lake Manyara National Park In Mto Wa Mbu, Tanzania, Madison Hoeninghausen

Independent Study Project (ISP) Collection

Human/wildlife conflict is a rapidly growing issue in the world today. As human population and development increase, wildlife habitat decreases, forcing humans and animals to share resources. One negative consequence of the human/wildlife interface is an alteration of behavior of wildlife in order to survive in new, high-stress environments. This study looks at the behavior of a troop of olive baboons residing on the border of Lake Manyara National Park in Mto wa Mbu, Tanzania. These animals leave the park each morning and spend their days in four surrounding habitats with varying levels of human presence: the main road, riverine …

Mongolian National Parks: Competing Interests And Institutional Viability In A Still Emerging Protected Areas System, Kieryn Wurts

Independent Study Project (ISP) Collection

In Mongolia, 17% of the total landmass is designated as one of four kinds of “protected areas”—Strictly protected areas, national parks, nature reserves, and natural historical monuments. This study focuses primarily on national parks as a civil institution, through on the ground interviewing of ten individuals employed in the protected areas system, field-notes and observations, and community surveying totaling 38 respondents at two research locations, Hustai-Nuruu National Park and Lake Khovsgol National Park. Protected areas are constructed civil spaces, and as a result are sites of competing societal interests--the interests of scientists and conservationists, of tourism and business interests, and …

Water Access And Security For Mongolian Peri-Urban Communities In The Face Of Climate Change And Development, Heather Cook

Independent Study Project (ISP) Collection

The paper attempts to assess how water access and security in Mongolian ger districts is impacted by the competing forces of climate change and development. The development of Mongolia is, understandably, a priority of the government and much of the populace, as are the impacts of climate change, which are well documented and acknowledged. Furthermore, these processes both have potentially adverse impacts on the overall well being of communities. In the context of water access and security, the need to strike this balance becomes even more acute. These factors can all be seen playing out in the city of Sainshand, …

Poaching As A Threat To Biodiversity And A Barrier To Sustainable Development In Western Uganda: A Case Study Of Queen Elizabeth National Park, Rwenzori Mountains National Park, Kibale National Park, And Surrounding Areas, Madeleine Torraca Jones

Independent Study Project (ISP) Collection

Despite efforts of the international community and individual countries to end poaching activities and target the markets which drive these activities, poaching continues to be a global problem. This paper will discuss the methods, findings, and recommendations that have resulted from a study on poaching in western Uganda. Uganda is both a transit country for illegal animal species and their derivatives from neighboring countries as well as a home to a number of species that are targeted by poachers. This makes Uganda an area of importance to the study of persistent poaching. Many of Uganda’s protected areas and native species, …

Independent Study Project (ISP) Collection

Climate change remains a prevalent problem for today’s international community, particularly for Pacific Island countries. This study examines the current influence of climate change on Samoa by looking at the three tenets of vulnerability: exposure, sensitivity, and adaptive capacity. These aspects of climatic change correlate and build off one another, ultimately elucidating the basic vulnerability of any given region. It also analyzes how environmentally secure Samoa is and will be, using Thomas Homer- Dixon’s theory on climate change and conflict. Finally, this paper seeks to outline the current system of adaptation awareness that exists between government, community and foreign aid …

Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin

Independent Study Project (ISP) Collection

This research paper examines the phenomenon of the recent trend of deforestation in the Pando department in northwestern Bolivia. Historically, the economy of Pando has always been based primarily in agro-forestal extraction activities that provided income to communities without the need to destroy the surrounding forests. The most important of these agro-forestal products have been rubber (primarily during the beginning of the 20th century) and more recently Castaña (Brazilian Nut). Recently however, as the result of various forces, the inhabitants of Pando have begun to cut down there forests at an alarming rate. The most relevant causes of this phenomenon …

A Preliminary Assessment Of Speleothem Sampling Methods For Paleoclimate Research, Sarah Truebe

National Cave and Karst Management Symposium 2013

Speleothems are incomparable archives of paleoclimate information. Most methods to extract past climate information from speleothems are necessarily destructive; sampling must occur along the growth axis. Development of sustainable methods for sampling these nonrenewable resources, whereby the needs of science and cave conservation are balanced, ought to be a priority of the paleoclimate community. Ergo, I am studying currently practiced methods in the field of speleothem paleoclimatology. Part 1 of this two-part study entails surveying active speleothem paleoclimatology labs nationally and internationally. The results of this portion of the survey will be converted to an anonymous list of current methods …

Upland Habitat Quality And Historic Landscape Composition Influence Genetic Variation Of A Pond-Breeding Salamander, Stephen C. Richter, Steve J. Price, Chelsea S. Kross, Jeremiah R. Alexander, Michael E. Dorcas

Forestry and Natural Resources Faculty Publications

Understanding the temporal and spatial scale at which habitat alteration impacts populations is important for conservation and management. Amphibians have declined more than other vertebrates, and pond-breeding species are particularly susceptible to habitat loss and fragmentation because they have terrestrial and aquatic life stages. One approach to management of pond-breeding species is protection of core upland habitat surrounding the breeding pond. We used genetic variation as an indicator of population status in a common amphibian species, spotted salamanders (Ambystoma maculatum), to determine how amount of suitable upland habitat relates to population status in the greater Charlotte, North Carolina, …

Elucidating The Population Dynamics Of Japanese Knotweed Using Integral Projection Models, Joseph T. Dauer, Eelke Jongejans

School of Natural Resources: Faculty Publications

Plant demographic studies coupled with population modeling are crucial components of invasive plant management because they inform managers when in a plant’s life cycle it is most susceptible to control efforts. Providing land managers with appropriate data can be especially challenging when there is limited data on potentially important transitions that occur belowground. For 2 years, we monitored 4 clonal Japanese knotweed (Polygonum cuspidatum) infestations for emergence, survival, shoot height until leaf senescence, dry shoot biomass after senescence, and rhizome connections for 424 shoots. We developed an integral projection model using both final autumn shoot height and shoot …

Behavioral Niche Partitioning In A Sympatric Tiger Beetle Assemblage And Implications For The Endangered Salt Creek Tiger Beetle, Tierney R. Brosius, Leon G. Higley

School of Natural Resources: Faculty Publications

How behavioral patterns are related to niche partitioning is an important question in understanding how closely related species within ecological communities function. Behavioral niche partitioning associated with thermoregulation is well documented in tiger beetles as a group. Co-occurring species of salt flat tiger beetles have adapted many thermoregulatory behaviors to cope with this harsh ecosystem. On first examination these beetles appear to occur in overlapping microhabitats and therefore compete for resources. To determine if behavioral niche partitioning is allowing multiple species to occur within the same harsh salt flat ecosystem we observed Cicindela nevadica lincolniana, Cicindela circumpicta, Cicindela fulgida, and …
