Examining The Impact Of Pau Jacaré (Piptadenia Gonoacantha) Growth On Soil Fertility In The Brazilian Atlantic Rainforest, Aleksandra Ponomareva

Environmental Analysis Program Mellon Student Summer Research Reports

The Atlantic Rainforest of Brazil is an area of astounding diversity in both flora and fauna, taking its place among the top five “biodiversity hotspots” in the world. However, in the past 40 or 50 years the area has been increasingly threatened by the presence of humans – approximately 93% of the Rainforest has disappeared as a result of exploitation (Turner 2004). Unsustainable farming practices, as well as logging, cattle ranching and mining activities have caused soil infertility, water depletion, erosion and destruction of ecosystems. This project examines the effects of the Pau Jacaré, Piptadenia gonoacantha, tree on soil health …

The Role Of Landscape Connectivity In Planning And Implementing Conservation And Restoration Priorities. Issues In Ecology, Doborah Rudnick, Sadie J. Ryan, Paul Beier, Samual A. Cushman, Fred Dieffenbach, Clinton Epps, Leah R. Gerber, Joel N. Hartter, Jeff S. Jenness, Julia Kintsch, Adina M. Merenlender, Ryan M. Perkl, Damian V. Perziosi, Stephen C. Trombulack

Geography

Landscape connectivity, the extent to which a landscape facilitates the movements of organisms and their genes, faces critical threats from both fragmentation and habitat loss. Many conservation efforts focus on protecting and enhancing connectivity to offset the impacts of habitat loss and fragmentation on biodiversity conservation, and to increase the resilience of reserve networks to potential threats associated with climate change. Loss of connectivity can reduce the size and quality of available habitat, impede and disrupt movement (including dispersal) to new habitats, and affect seasonal migration patterns. These changes can lead, in turn, to detrimental effects for populations and species, …

The Impact Of Income Generating Programs At Tarangire National Park, Tanzania, Dylan Mcdowell

Independent Study Project (ISP) Collection

Tarangire National Park (TAR) is Tanzanian’s third largest grossing park, and is surrounded by 42 villages in five districts. The park’s single Outreach Warden has undertaken many projects since the park’s creation in 1970 to engage the villagers in natural resource conservation, including wildlife. The newest pilot project at TAR is Income Generating Programs (IGP) where community groups organize themselves around an activity that earns income. From September 24-29, 2012, TAR selected 10 members from three groups in the park’s northern end and 15 members from two groups in the park’s southern end to attend an all-expenses paid business class …

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia

Fisheries Management Papers

The Department of Fisheries (Department) is proposing a new simplified management approach which focuses on fishing as the core criteria in the new licensing framework. Given the low level of impact of aquatic eco-tours and shore-based fishing, consideration is being given to removing the need for these activities to be formally licensed. The Department is of the view that these activities can be adequately managed by regulations that have broader application across the community.

The current management, licensing and fee structures are complex and provide limited business flexibility. A simplified management approach will also improve the Department’s capacity to monitor …

Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper

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

Many species of grassland birds are area sensitive, which may exacerbate the ecological effects of the extensive loss and fragmentation of grasslands that has taken place across the northern Great Plains. However, the reasons for this area sensitivity are unclear, as vegetation structure, matrix composition, and restriction of movements among patches do not seem to provide viable explanations for species native to grasslands. Con specific attraction, whereby species are behaviorally stimulated to select habitat or establish territories near individuals of the same species, may help explain this area sensitivity. We review and discuss theoretical and empirical research on avian conspecific …

Who Else Would Plant The Trees? A Status Update On The Pemba Flying Fox, Hannah “Hawa” Grose, Catherine Grace “Rahma” Clemmens

Independent Study Project (ISP) Collection

This study assesses the current population of Pemba Flying Fox, Pteropusvoeltzkowi, at four key locations on Pemba Island off the coast of Tanzania previously noted as highly populated roost sites: Ngezi National Forest, Wete, Kidike, and MsituwaMbiji. We evaluate local knowledge, perceptions, and practices of communities surrounding the Pemba Flying Fox. This study also documents roosting and migratory patterns of the bats. We hypothesize a growth in bat population, an overall positive community perception of the bats, and a greater amount of conflict between fruit farmers and Pteropusvoeltzkowi. Results showed a decrease in estimated population. Additionally, reverse correlation was found …

Demographic And Genetic Consequences Of Small Population Size In Remnant Populations Of Arabis Georgiana Harper (Georgia Rockcress), Alicia M. Garcia

Theses and Dissertations

The goal of this thesis is to provide a greater scientific understanding of the demographic and genetic consequences of small population size in remnant populations of Arabis georgiana Harper (Georgia Rockcress). Specifically, 1 ) traits associated with phenological progression, fitness and reproductive success were compared between naturally occurring "native" plants and plants grown ex situ and subsequently restored to one of the largest remaining populations of A. georgiana, and 2) a preliminary analysis of population genetic structure in remnant populations across the species' range was performed. In addition to updating census information on remnant populations of A. georgiana, chapter one …

Using The Internet To Understand Angler Behavior In The Information Age, Dustin R. Martin, Brenda M. Pracheil, Jason A. Deboer, Gene R. Wilde, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Declining participation in recreational angling is of great concern to fishery managers because fishing license sales are an important revenue source for protection of aquatic resources. This decline is frequently attributed, in part, to increased societal reliance on electronics. Internet use by anglers is increasing and fishery managers may use the Internet as a unique means to increase angler participation. We examined Internet search behavior using Google Insights for Search, a free online tool that summarizes Google searches from 2004 to 2011 to determine (1) trends in Internet search volume for general fishing-related terms and (2) the relative usefulness of …

Current Status And Long-Term Trends In Water Quality And Living Resources In The Virginia Tributaries And Chesapeake Bay Mainstem From 1985 Through 2011, Daniel M. Dauer, Harold G. Marshall, John R. Donat, Michael F. Lane, Suzanne C. Doughten, Cindy Johnson

Status and Trends for Virginia Chesapeake Bay

The period prior to the implementation of the Chesapeake Bay Monitoring Program was characterized by a marked decline in the water quality of the Chesapeake Bay. The disappearance of submerged aquatic vegetation in certain regions of the Bay, declines in the abundance of some commercially and recreationally important species, increases in the incidence of low dissolved oxygen events, changes in the Bay's food web, and other ecological problems have been related to the deteriorating water quality (e.g. USEPA, 1982,1983;Officer et al.,1984; Orth and Moore, 1984). The results of concentrated research efforts in the late 1970s and early 1980s stimulated the …

Impacts Of Climate Change On The Surface Water Balance Of The Central United States, 1984–2007, Bo Dong

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

The climate system and the hydrologic cycle are strongly connected with each other. Understanding the interactions between these two systems is important, since variations in climate can trigger extensive changes in the hydrologic cycle, with significant impacts on agriculture, ecosystems, and society. Observations over the central U.S. in recent decades show numerous changes in climatic variables. This includes decreases in cloud cover and wind speed, increases in air temperature, and seasonal shifts in precipitation rate and rain/snow fraction. To assess the impacts of these variations in climate on the regional water cycle, a terrestrial ecosystem/land surface hydrologic model (Agro-IBIS) is …

Sumak Allpa is a 113.15-hectare island on the Napo River in the Orellana Province of Amazonian Ecuador that has been functioning as a primate sanctuary since 2005. Squirrel monkeys were surveyed during 1 to 3 hour observation walks in the mornings, afternoons, and evenings. During two occasions, the island was divided among multiple observers at the same time, including one observer in a canoe on the exterior of the island, to allow …

Genetically Modified Organisms As A Potential Solution For Decreasing Hunger In Developing Nations: An Ethical Paradox, Rachel Sherman

Independent Study Project (ISP) Collection

I first became aware of and interested in genetically modified organisms (GMOs) in the “Politics of Food in America” course I took spring semester of 2012, my junior year at the University of Texas at Austin. I was intrigued by the fact that such a concept was so unfamiliar to the public, yet genetically engineered products were in our everyday foods. Though I received a basic introduction to GMOs through my course, I was curious to learn more about the regulatory practices of GM crops and the political relationships sustained by GM firms and government agencies in the United States. …
