Forest Edge Effects On The Behavioral Ecology Of L'Hoest's Monkey (Cercopithecus Lhoesti) In Bwindi Impenetrable National Park, Uganda, Tharcisse Ukizintambara

Antioch University Dissertations & Theses

Forest edges are associated with forest edge effects that result from changes in physical features of the habitat, predator species and number, and prominence of human activities and other disturbances that can have direct or indirect impact on the distribution, ecology, and fitness of forest plant and animal species. I conducted a literature review on edge effects on primate species and came up with a classification of primate species in three general categories " thriving, sensitive and resilient species to edge effects " based on behavioral and demographic responses.

In Bwindi Impenetrable National Park, edge effects followed non-monotonic patterns (wave-like) …

Assessing Annual And Seasonal Spatial Variability Of Ambient Pm10 Using Linear Regression Analysis In A United States-Mexico Urban Sprawl, Mario Ivan Garcia

Open Access Theses & Dissertations

As air quality issues grow progressively in the consciousness of the global community, stakeholders are pressing for epidemiologic studies of air pollution. The effects of chronic exposure to ambient air pollution remain a difficult challenge due to its substantial small-scale spatial variation. Recent approaches to assess intra-urban exposure have employed the use of proximity-based assessment, interpolation methods, emission-meteorological models, dispersions models, and land-use regression (LUR) models.

This thesis assesses the spatial variability of ambient particulate matter (PM10) obtained by five self-governing models for the area of El Paso. Using multiple linear regression analysis five regression-based equations were developed to predict …

The Effect Of Dietary Supplement On Risk Of Infection In Community Based Patients With Type Two Diabetes Mellitus, Mamoon Ibrahim Abu Haltem

Theses

Background: Type Two diabetes mellitus prevalence is increasing dramatically universally and locally. Diabetic patients have shown higher risk of infections and associated morbidity. Many factors contribute to this, including poor nutritional status of this population. The lack of evidence in this field inspired us to look at the relationship between the dietary supplements and risk of infection in these patients.

Objective: To measure the effect of dietary supplement on risk of infection in community based patients with type 2 diabetes mellitus.

Methods: Following informed written consent 100 diabetic patients have been randomly assigned to receive either an oral dose of …

The Effect Of Visfatin And Adiponectin On Metabolic Parameters Of An Animal Model Of Type 2 Diabetes, Thuraya Saeed Ali Alshamisi

Theses

Background: Diabetes mellitus (DM) is one of the most common exocrine disorders affecting more than 6% of the world’s population. The incidence and prevalence of this chronic disease are on the rise in many parts of the world including the Middle East. DM is caused by defective Insulin production, release and/or function. The causes and nature of abnormal insulin metabolism is less than clear. While defective insulin secretion is observed in type 1 diabetes, insulin resistance is predominant in type 2 diabetes, which affects more than 94% of the diabetic patients.

Materials and Methods: Rats between the age of two …

Endocrine Disruptors And Obesity: An Examination Of Selected Persistent Organic Pollutants In The Nhanes 1999-2002 Data, Mai A. Elobeid, Miguel A. Padilla, David W. Brock, Douglas M. Ruden, David B. Allison

Psychology Faculty Publications

Recent evidence suggests that endocrine disrupting chemicals (EDCs) may cause perturbations in endogenous hormonal regulation that predispose to weight gain. Using data from NHANES (1999-2002), we investigated the association between body mass index (BMI), waist circumference (WC) and selected persistent organic pollutants (POPs) via multiple linear regressions. Consistent interaction was found between gender, ln oxychlordane and ln p,p' DDT. Also, we found an association between WC and ln oxychlordane and ln hpcdd in subjects with detectable levels of POPs, whereas an association between WC and ln p,p' DDT was observed in all subjects. Furthermore, ln Ocdd showed an increase with …

From The Bronx Into The Wild! My Adventurous Experience At The Bronx Zoo, Lauren Noll

Student Theses 2001-2013

Many people defend zoos, claiming that they provide great opportunities in education, scientific research, and the overall preservation of wildlife worldwide. However, many people will take the opposing side, arguing that it is wrong to deprive animals of their natural habitats and lifestyles. One of the greatest controversies of our time pertains to the moral issues associated with keeping animals in captivity, such as in zoos and aquariums.

The Effects Of Pulsed Exposures Of Suspended Clay On The Survival, Growth, And Reproduction Of Daphnia Magna, Sarah Robinson

All Theses

Suspended sediments are a natural component of aquatic ecosystems but anthropogenic activity such as land development can result in significant increases, especially following rain events due to surface erosion. Continuous exposures of suspended clay and silt have been shown to effect growth and reproduction of Cladocera, leading to a decrease in population growth rate. The mechanism of clay toxicity in these filter-feeding organisms is clogging of the gut tract resulting in decreased food uptake and assimilation. When placed in clean water, daphnids can purge clay from their gut and recover. In many surface waters, aquatic organisms experience episodic exposures of …

Costs Of Implementing Collective Action And Capacity Building Among Pastoralists In Southern Ethiopia, D. Layne Coppock, Seyoum Tezera, Solomon Desta

Environment and Society Faculty Publications

Since 2000, the PARIMA project has implemented risk-management activities among semi-settled pastoralists in southern Ethiopia. The goal has been to improve human welfare via collective action and capacity building. Outcomes include progress in income generation, asset conservation, and livelihood diversification. Fifty-nine collective-action groups were created. Dominated by women, they included over 2,000 founding members and groups have recently merged to form 37 cooperatives, consistent with government policy. Creating sustainable impacts via collective action and capacity building requires many inputs. Taking raw, illiterate volunteers and transforming them into sustainable groups took up to three years, on average. Costs of implementing this …

Environment and Society Faculty Publications

The PARIMA project was created to improve the well-being of pastoralists and agro-pastoralists in northern Kenya and southern Ethiopia via risk-management research, training, and outreach. The project began to collaborate with Egerton University’s Department of Natural Resources in 1998 and many joint activities were undertaken over the next 11 years. Among them were regional household research on pastoral risks and their management, a training program for Egerton teaching staff to obtain post-graduate degrees, facilitation of Egerton faculty and staff to attend professional meetings, and provision of computer hardware and software that led to the creation of a GIS teaching and …

Simple Cooling Method Improves The Quality Of Marketed Camel Milk In Northern Kenya, D. Layne Coppock, A. O. Adongo, F. Wayua, I. J. Sagalla, H. K. Walaga, C. Amboga

Environment and Society Faculty Publications

Milk marketing is important for many pastoralists to generate income, especially poor households with little else to sell. Milk is accumulated at pastoral settlements and transported to local markets on foot, by pack animals, or in vehicles. Despite challenges of heat and long-distance travel, pastoralists or traders do not attempt to cool marketed milk and possibly reduce risk of spoilage. Milk spoilage is an important problem that limits urban consumer demand. Our research objective was to determine effects of water-soaked hemp (burlap), wrapped around plastic jerry cans, on reducing milk temperature and enhancing quality of marketed camel milk, a key …

Can Pastoral Linkages To Livestock Markets Be Sustained In Southern Ethiopia?, D. Layne Coppock, Getachew Gebru, Solomon Desta, Seyoum Tezera, Zewdu Edea

Environment and Society Faculty Publications

The PARIMA project has facilitated collective action, empowerment of women, and increased involvement in livestock marketing among pastoralists on the Borana Plateau since 2001. Fifty-nine collective-action groups formed by PARIMA and her partners have been recently merged into market-oriented cooperatives, consistent with government policy. We used focus groups and participatory appraisals to assess the extent that market linkages have been sustained since previously reported in 2006. The markets have been growing, but are volatile. Members report they need access to early warning and livestock market-information systems, as well as more capital, to promote trade. Export firms have imposed added conditions …

Similarity Of Nutrient Uptake And Root Dimensions Of Engelmann Spruce And Subalpine Fir At Two Contrasting Sites In Colorado, Melissa S. Lucash, Ruth D. Yanai, Karis J. Mcfarlane, Sarah E. Kulpa, Dustin M. Wood

Environmental Science and Management Faculty Publications and Presentations

Nutrient uptake capacity is an important parameter in modeling nutrient uptake by plants. Researchers commonly assume that uptake capacity measured for a species can be used across sites. We tested this assumption by measuring the nutrient uptake capacity of intact roots of Engelmann spruce (Picea engelmanni Parry) and subalpine fir (Abies lasiocarpa (Hook.) Nutt.) at Loch Vale Watershed and Fraser Experimental Forest in the Rocky Mountains of central Colorado. Roots still attached to the tree were exposed to one of three concentrations of nutrient solutions for time periods ranging from 1 to 96h, and solutions were analyzed for ammonium, …

“Mangra”- Exploring The Organization Of An Environmental Education Curriculum In A Village Equipped For Sustainable Development, Abigail Phillips

Independent Study Project (ISP) Collection

The rapid growth of urban centers in the last century has resulted in obvious social stratification and neglect of the natural environment. Not only is the gap between rich and poor increasing, but the resources that supply urban consumption and community development are increasingly depleted without due recognition. These issues are successfully addressed in some communities by drawing example from more traditional practices of ecological management, such as water conservation and local food production. Environmental education could be utilized to aid in the relief of social issues and environmental degradation if the curriculum is specialized for each community’s circumstance. Children …

Testing The Baobab’S Mettle: An Evaluation Of The Sustainability And Economic Potential Of Harvesting Adansonia Digitata, Benjamin Rhodes

Independent Study Project (ISP) Collection

In light of southern Africa’s growing population and economy, as well as the increasing international market for Adansonia digitata products, it seems important to ascertain whether or not rural baobab harvesting is having an impact on the health of the trees and whether it could be improved or expanded to increase benefits to communities. This study focused on 72 trees in and around the village of Gweta, Botswana, examining local usage and harvesting practices and exploring their correlations with the health of the trees. Results suggest that baobab harvesting in its current form is detrimental to the trees’ health and …

Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender

Human–Wildlife Interactions

Rocky Mountain National Park (RMNP) has supported a small black bear (Ursus americanus) population of low productivity. Increased visitor use of the park and development around its periphery could lead to a reduction in population viability of RMNP’s bear population or could increase the potential for human–bear conflict. Therefore, we investigated contemporary survival and productivity parameters for RMNP’s black bear population from 2003 to 2006 and compared these values to historic levels (1984–1991) and population means throughout the western United States to clarify the current status of RMNP’s bear population. The contemporary black bear population showed signs of …

Phenotopic Plasticity Of Leaf Shape Along A Temperature Gradient In Acer Rubrum, Dana L. Royer, Laura A. Meyerson, Kevin M. Robertson, Jonathan M. Adams

Natural Resources Science Faculty Publications

Both phenotypic plasticity and genetic determination can be important for understanding how plants respond to environmental change. However, little is known about the plastic response of leaf teeth and leaf dissection to temperature. This gap is critical because these leaf traits are commonly used to reconstruct paleoclimate from fossils, and such studies tacitly assume that traits measured from fossils reflect the environment at the time of their deposition, even during periods of rapid climate change. We measured leaf size and shape in Acer rubrum derived from four seed sources with a broad temperature range and grown for two years in …

Putting Trees Back In The Hands Of Malians: L’Association Malienne Pour La Conservation De La Faune Et De L’Environnement And The Balance Between Using And Protecting Local Forests, Cara Peterson

Independent Study Project (ISP) Collection

Products from trees provide the essential human necessities of food and shelter, as well as the means to cook and construct them with firewood and lumber. With the earth’s ever increasing population and growing industries, these needs have also risen, and forests worldwide are feeling the strain of deforestation and over usage for both commercial and household consumption. Deforestation in Africa is occurring at a smaller scale than on other continents, but this does not mean it is any less damaging to local ecosystems (Bessassen, 2009, p. 76). In fact, African forests are particularly stressed because approximately 90% of the …

Effects Of Re-Grown Forest Habitat On Lemur Catta Behavior, Sophie Ackoff

Independent Study Project (ISP) Collection

This study examines the effects of re-grown forest habitat on L. catta behavior at Berenty Private Reserve in Southern Madagascar during the early wet season. Evaluation of the reforested area versus natural forest revealed significant differences in species composition and food availability. Though the re-grown forest showed signs of forest regeneration and total greater food availability, the natural forest of Malaza proved to contain more preferred food sources for L. catta. Behavioral observations were collected over eight full-day troop follows and showed significant differences in feeding behavior, activity budget, and intra-troop and inter-troop aggressions. The WELL troop in Ankoba, the …

Land Conservation And Land Use In New England: Trends, Challenges & Opportunities, Amanda Loomis, Tom Devine, Andrea Small, Brittany Howard, Brett Richardson, Stephanie Dulac

Land Conservation

Sprawling development patterns accelerated across the New England landscape in the last three decades and consumed the region‘s forests, farms, and open spaces at an unprecedented rate. New England‘ers in all six states formed land trusts, supported statewide conservation organizations, and collaborated with state and federal partners to protect some of their most-prized recreation lands, wildlife habitats, and working lands. The current economic recession has slowed development pressures across the region and offers an opportunity to build on recent successes. The time is right to plan a coordinated New England conservation strategy that protects and links the region‘s natural assets. …

The Influence Of Mastication On Soils And Fuels In Moist And Dry Forests Of The Northern Rocky Mountains, Theresa Jain, Russel T. Graham

North American Forest Ecology Workshop

We evaluated the applicability of mastication as a fuel treatment alternative within Northern Rocky Mountain moist and dry forests to treat post-harvest activity slash (moist forest) and standing trees (dry forest). On the moist forest site, we compared four different slash treatments, mastication, machine grapple piling, lop and scatter, and a control within a wildland urban interface setting to determine the effects of these treatments on soil nutrition, forest floor depth, and woody debris distributions. We randomly assigned the slash treatments and controls to 12 one-acre plots. Nitrogen, soil carbon, and magnesium concentrations within the soil components were not significantly …
