Renewable Energy And Agriculture: Promoting Biogas In The Rural Communities Of The Lashihai Wetland Nature Reserve, Amanda Lee

Independent Study Project (ISP) Collection

“China’s economic miracle will end soon because the environment can no longer keep pace.” – Pan Yue, deputy environmental director (Larson, 21)

In recent years, the causes and impacts of global warming have increasingly garnered press on an international scale. Scientists have confirmed global warming as being mostly anthropogenic (Rosenthal and Revkin; Xuequan). More wildlife species have become endangered or extinct (Roach) and natural disasters such as storms have increased in severity (“New study”; Schmid). With the 2008 Beijing Olympics quickly approaching, the international community has turned its eye to China and its policies, including those towards the environment. Since …

Getting Started With Psleuth, Qingfeng (Gene) Guan

School of Natural Resources: Faculty Publications

SLEUTH1 is a Cellular Automata (CA) model of urban growth and land use change simulation and forecasting, developed in the Department of Geography, University of California, Santa Barbara (Clarke, Hoppen, and Gaydos 1997; Clarke and Gaydos 1998; Silva and Clarke 2002).

A classical Cellular Automata model is a set of identical elements, called cells, each one of which is located in a regular, discrete space, called cellspace. Each cell is associated with a state from a finite set. The model evolves in discrete time steps, changing the states of all its cells according to a transition rule, homogeneously and synchronously …

Getting Started With Prpl, Qingfeng Guan

School of Natural Resources: Faculty Publications

pRPL is an open-source1 general-purpose parallel Raster Processing programming Library developed by Qingfeng Guan, in the Department of Geography, University of California, Santa Barbara. pRPL encapsulates complex parallel computing utilities and routines specifically for raster processing (e.g., raster data decomposition, distribution and gathering among multiple processors, inter-processor communication and data exchange), and provides an easy-to-use interface for users to parallelize almost any raster processing algorithm with any arbitrary neighborhood (or moving window) configuration. pRPL enables the implementation of parallel raster-processing algorithms without requiring a deep understanding of parallel computing and programming, thus it greatly reduces the development complexity. Moreover, even …

Synoptic Monitoring Of Gross Primary Productivity Of Maize Using Landsat Data, Anatoly A. Gitelson, Andrés Viña, Jeffrey G. Masek, Shashi Verma, Andrew E. Suyker

School of Natural Resources: Faculty Publications

There is a growing interest in monitoring the gross primary productivity (GPP) of crops due mostly to their carbon sequestration potential. Both within- and between-field variability are important components of crop GPP monitoring, particularly for the estimation of carbon budgets. In this letter, we present a new technique for daytime GPP estimation in maize based on the close and consistent relationship between GPP and crop chlorophyll content, and entirely on remotely sensed data. A recently proposed chlorophyll index (CI), which involves green and near-infrared spectral bands, was used to retrieve daytime GPP from Landsat Enhanced Thematic Mapper Plus (ETM+) data. …

Formal Education For Sustainable Development, Caryn Saslow

Independent Study Project (ISP) Collection

Over the next 50 years, humans will make the choice as to whether or not they would like to mitigate or exacerbate global warming. Seeing as now is a crucial time in which to enact change, why is it that the issues inherent in sustainable development are not currently a compulsory part of primary and secondary school education within the developed Western world? If our children stand to inherit our environmental, social, and economic problems, it is our responsibility to supply them with the tools to survive through such adversity. This paper examines the history of the concept of sustainable …

Post-Fire Demography Of A Dry Eucalypt Forest In The Midlands, Tasmania: A Pilot Study, Christine Urbanowicz

Independent Study Project (ISP) Collection

There have been many efforts to regenerate the threatened and declining dry eucalypt forests found within the Midlands of Tasmania. This pilot study was completed as part of a larger research project on eucalypt regeneration. Researchers need to know where recruits are most successful in order to appropriately place regeneration microsites. I have begun characterizing the baseline demography of a recently burnt remnant forest. I had two objectives: 1. to characterize the stand structure where recruits are successful, and 2. to describe where the recruits are within this structure. Data on location, size, and life history stage of trees were …

Arauco Y Sus Políticas De Rse En La Viii Región Del Bío Bío (Una Comparación Entre Sus Políticas Medio Ambientales Y La Situación Real), Jamie Warner

Independent Study Project (ISP) Collection

The purpose of my independent research project is to find out whether the written Corporate Social Responsibility environmental policies of Arauco Forests are actually enacted in the eight region (Bíobío). My hypothesis is that even though Arauco has implemented these policies, it does not have a sustainable model for its forest industry. Arauco continues to damage the land, water, and air in the Biobió region, which is in turn affecting the lives of the people that live in the region, the natural flora and fauna, and the workers. I have chosen to focus on the VIII region because it has …

A Reassessment Of Avian Assemblages Along The Lakes Corridor In The Atherton Tablelands, North Queensland, Shaina N. Stewart

Independent Study Project (ISP) Collection

Forest fragmentation is the process by which large areas of continuous forest are replaced by foreign ecosystems that restrict native growth to isolated patches. Biota remaining within these fragmented environments often suffer consequences that stem from reduced forest area. Wildlife corridors—linear patches of habitat that connect remnant fragments—have frequently been proposed to alleviate fragmentation effects by facilitating biotic movement between forest patches. Initiated in 1998, the Lakes Corridor on the Atherton Tablelands in North Queensland, Australia, connects the two formerly isolated sections of Crater Lakes National Park with the goal of promoting wildlife dispersal between them. This study monitored avian …

La Sucesión Primaria De La Vegetación Sobre Los Flujos Piroclásticos Del 2006 En El Volcán Tungurahua, Lauren Schaefer

Independent Study Project (ISP) Collection

A year and a half after the August 2006 eruption of the Tungurahua volcano, the vegetative growth on the pyroclastic flows is young and scarce. To determine the types of plants and the mechanisms which control the dynamics of vegetative recovery, two transects were made; one in the Cusúa gorge and the other in the Bascún gorge in which the type, quantity and ages of the plants were noted. A third transect of vegetation not directly affected by the 2006 flows was made near the Bascún gorge for comparison purposes. In the two main sites, a total of 47 species …

The Current State Of Populations Of Diadema Antillarum On Isla Colón In Bocas Del Toro, Panamá, 25 Years After Mass Mortality, Leah T. Ritz

Independent Study Project (ISP) Collection

In January 1983, the worst recorded die-off of any marine animal hit the Caribbean beginning near the mouth of the Panama Canal and eventually wiping out nearly 99% of one of the most important herbivores in coral reef communities, Diadema antillarum—the long-spined sea urchin or Diadema. No populations of Diadema in the Western Atlantic are known to have escaped the drastic population declines. The loss of Diadema throughout the Western Atlantic has had long-lasting impacts on the structure and composition of many types of communities including coral reefs, mangrove roots, sea grass beds, and sand flats. Though the mortality was …

Storybooks: A Teaching Tool For Sustainability, Amanda Medress

Independent Study Project (ISP) Collection

If today’s children learn to make decisions with the environment in mind, tomorrow’s future will be cleaner, greener, and energy leaner. Storybooks, which are a creative and imaginative learning tool, can influence children to pursue sustainable lifestyles. Early education through literature can help green decisions be the default mode for the next generation.

This project has two components. The first is to produce research on the following question: what kind of storybook instills environmental regard and motivates sustainable behavior? The second is to produce a children’s adaptation of Greeniology, a green living guide by Tanya Ha, which utilizes the findings …

Atravesando La Amazonía: Carreteras, Desarrollo, & El Camino Del Desastre, Olivia De Lancie

Independent Study Project (ISP) Collection

Road construction in the Amazon has greatly impacted its floral and faunal inhabitants. The opening of a new road in a previously isolated region exposes its populations to the economy for the first time, and to the possibility of enriching themselves through the extraction of their products. Unfortunately, this exchange of goods results in the aculturization of indigenous groups, and in the loss of their unique culture. The migration that the roads near indigenous communities encourages increases access to education and sources of work, but results in a nearly complete destruction of these communities’ social fiber. Economic and cultural exchanges …

Securing Environmental Flows on the Colorado River in an Era of Climate Change: Issues, Challenges and Opportunities (March 21)

The Colorado River is the primary surface water resource of the Southwest, providing water to approximately 30 million residents. Studies and policy decisions associated with a recently completed EIS point to an ever-tightening water supply due to longstanding growth pressures exacerbated by significant climate change impacts. Given these trends, how can the river’s environmental needs be satisfied?

On March 21st, the Center’s Western Water Policy Program brought together four leading Colorado River experts along with an audience of approximately 70 water professionals to discuss “Securing Environmental Flows on the Colorado River in an Era of Climate Change: Issues, Challenges, and …

A Bioenergetic Model For Zebrafish Danio Rerio (Hamilton), Christopher J. Chizinski, B. Sharma, K. L. Pope, Kevin L. Pope, R. Patinos

School of Natural Resources: Faculty Publications

A bioenergetics model was developed from observed consumption, respiration and growth rates for zebrafish Danio rerio across a range (18–32° C) of water temperatures, and evaluated with a 50 day laboratory trial at 28° C. No significant bias in variable estimates was found during the validation trial; namely, predicted zebrafish mass generally agreed with observed mass.

Review Of Oology And Ralph's Talking Eggs By Carrol L. Henderson, Kristin R. Johnson

The Prairie Naturalist

Ralph Handsaker was an Iowan farmer whose "ravenous curiosity" (page 4) about the natural world inspired him to become an oologist, or egg collector. This book tells the story of Handsaker's eggs, contained in two large cabinets that remained hidden in the living room of his boarded-up house after his death in 1969, until they were rediscovered in 2003 and shown to the author, wildlife conservationist, and photographer, Carrol Henderson. Ralph's eggs can "talk" by virtue of Henderson's chronicle-using the eggs as guides-of not only Ralph's own passion for natural history and egg collecting, but also the history of conservation …

Raptor Use Of Artificial Perches At Natural Areas, City Of Fort Collins, Colorado, G. W. Witmer, Michael Pipas, Patrick Burke, David Rouse, Donna Dees, Karen Manci

The Prairie Naturalist

The black-tailed prairie dog (Cynomys ludovicianus) remains a critical element of the prairie ecosystem even though its numbers and occupied range have declined dramatically since the arrival of Europeans in North America (Antol in et al. 2002). Prairie dog colonies are used by many species of wildlife and help maintain high levels of biodiversity (Kotliar et al. 1999). In the urban-suburban setting, the occurrence of prairie dog colonies also provides opportunities for wildlife viewing and environmental education. Unfortunately, prairie dogs also can come into conflict with humans, especially in the urban-suburban setting, where they cause vegetation and property …

Breeding By The Snowy Plover In North Dakota And South Dakota, Carol Aron, Paul Van Ningten, Michael Rabenberg, Cheryl Jacobs, Greg Pavelka, Ricky D. Olson

The Prairie Naturalist

The snowy plover (Charadrius alexandrinus) is a small shorebird that breeds on unvegetated beaches along coastlines, rivers, and alkaline lakes. In North America, its breeding distribution extends along the coasts of California, Oregon, and southern Washington, where the population is listed as federally threatened (USFWS 1993), and an interior population occurs on wetlands in western and central states and central Mexico (Page et al. 1995). There have been rare breeding reports in Montana, Wyoming, and Saskatchewan (Page et al. 1995), but no documented breeding records in North Dakota or South Dakota. However, the United States Army Corps of Engineers reported …

Low Reproductive Success Of Mallards In A Grassland-Dominated Landscape In The Sandhills Of Nebraska, Johann A. Walker, Zach J. Cunningham, Mark P. Vrtiska, Scott E. Stephens, Larkin Powell

The Prairie Naturalist

The Sandhills of Nebraska comprise approximately 5,000,000 ha of native grassland interspersed with numerous groundwater-fed wetlands. A substantial population of the mallard (Anas platyrhynchos) nests in this region. Previous investigations of nest survival probability of ducks in the Sandhills have estimated surprisingly low rates of nest survival for a grassland-dominated landscape. These investigations were conducted on public lands and most nest searching took place near wetlands where activity of nest predators might be highest. We predicted that mallards would nest at varying distances from wetlands and that survival probability of a representative sample of duck nests would increase …
