Caribbean Coastal Marine Productivity (CARICOMP) was a basin-wide cooperative, international network of marine laboratories established in 1985. Recognizing major trends of change in coastal ecosystems and the importance of the linkages among them, our goal was to monitor synoptically with standardized methods the physical environment and to document trends in measures of the structure and functioning of coral reefs, seagrasses and mangroves. Between 1985 and 1993, the CARICOMP Steering Committee established a data management center and wrote a methods manual. Marine laboratories joined the program by appointing a Site Director and signing an agreement specifying the cost sharing and responsibilities …

Branding And Marketing For An Environmental Nonprofit Organization: Revitalizing A Brand In Southern Illinois, Erik Fitzgerald
Branding And Marketing For An Environmental Nonprofit Organization: Revitalizing A Brand In Southern Illinois, Erik Fitzgerald
Research Papers
Due to its ‘social image’ nonprofits have avoided marketing in the past, focusing their efforts on fundraising and promotional activities. Growing competition within the nonprofit sector has forced these organizations to re-evaluate how they think about marketing. Marketing- oriented nonprofits are out-performing their competitors who have been slow to adapt to this increasingly competitive environment. This project takes a look at a local nonprofit, the Friends of the Shawnee National Forest, that has yet to adopt this marketing orientation. This research gives insight into how a small environmental nonprofit in southern Illinois can use branding and marketing strategies to increase …

As concentration in the surface water at the wetland inlet was 0.85±0.26 mg L-1, and 0.02±0.01 mg L-1 at the wetland outlet. It was observed that the As level in water decreased significantly along its flow path, with an As removal efficiency of 98 %. As concentration in the sediment was 89.53-356.22 mg kg-1 at …
Application Of A Mixed Order Model To Determine The Rate Adsorption Of 1-Nitronaphthalene Onto Activated Carbon, Suntree Rincome
Application Of A Mixed Order Model To Determine The Rate Adsorption Of 1-Nitronaphthalene Onto Activated Carbon, Suntree Rincome
Applied Environmental Research
This study investigated the adsorption kinetics of 1-nitronaphthalene solution (a polycyclic aromatic hydrocarbon, PAH) onto seven different masses of activated carbon. The coefficient of determination (r2) was used to determine the best-fit kinetic model and to confirm agreement between experimental data and the kinetic rate equations. The results indicated that adsorption could be defined with masses of 0.0200 g and 0.0501 g when fitted using a second order rate equation. Adsorption on to masses of 0.1003 g, 0.1203, 0.1501 g, and 0.2001 g was best defined when data were fitted to a pseudo second order rate equation. However, adsorption onto …

The Water Changed Me As A Person: How Childhood Experiences With Water Affect Behavior And Attitudes Towards Water As An Adult, Victoria Heim
The Water Changed Me As A Person: How Childhood Experiences With Water Affect Behavior And Attitudes Towards Water As An Adult, Victoria Heim
Honors Theses
This research serves to identify how childhood experiences with water impact a person’s attitudes and behaviors towards water issues later in life. Current research looks at more one-dimensional studies, such as only attitudes and behaviors from childhood, or not exploring multiple variables such as gender and community type and childhood experiences. By interviewing two distinct groups of students in terms of typical environmental attitudes and behaviors expressed by members of each group or political party, the College Republicans and the Office of Sustainability, we can see how the individual respondents from each group may have had childhood experiences that shaped …

Sources Of Carbon To Suspended Particulate Organic Matter In The Northern Gulf Of Mexico, Kelsey L. Rogers, Samantha H Bosman, Sarah Weber, Cedric Magen, Joseph P. Montoya, Jeffrey Chanton
C-IMAGE Publications
Suspended particulate organic carbon (POCsusp) in the Gulf of Mexico is unique compared to other seas and oceans. In addition to surface primary production, isotopic analysis indicates that microbial cycling of oil and riverine inputs are primary sources of carbon to POCsusp in the Gulf. To characterize POCsusp from seep sites and non-seep north central Gulf (NCG) sites potentially affected by the Deepwater Horizon (DWH) spill, we analyzed 277 and 123 samples for δ13C and Δ14C signatures, respectively. Depth, partitioned into euphotic ( < 300 m) and deep ( > 300 m), was the main driver of spatial δ …
Application Of Analytical Techniques In Food Product Development, Sonali R. Pandey
Application Of Analytical Techniques In Food Product Development, Sonali R. Pandey
Electronic Theses and Dissertations
Products are analyzed in major sectors of food industry to meet regulatory standards, food safety, quality control, and research and development. Analytical and extraction techniques have been applied for simultaneous investigation of multiple product characteristics. Food analysis faces critical challenges due to the complex composition of food, leading to matrix effects that result in loss of accuracy and reliability. The analytical techniques require an efficient sample preparation to avoid or minimize matrix effects. Solid-phase extraction has been widely used to address this issue. In this dissertation, the aim is to apply analytical techniques in food product development. To accomplish this, …

How Are Interannual Variations Of Land Surface Phenology In The Highland Pastures Of Kyrgyzstan Modulated By Terrain, Snow Cover Seasonality, And Climate Oscillations? An Investigation Using Multi-Source Remote Sensing Data, Monika Anna Tomaszewska
Electronic Theses and Dissertations
In the semiarid, continental climates of montane Central Asia, with its constant moisture deficit and low relative humidity, agropastoralism constitutes the foundation of the rural economy. In Kyrgyzstan, an impoverished, landlocked republic in Central Asia, herders of the highlands practice vertical transhumance—the annual movement of livestock to higher elevation pastures to take advantage of seasonally available forage resources. Dependency on pasture resource availability during the short mountain growing season makes herds and herders susceptible to changing weather and climate patterns. This dissertation focuses on using remote sensing observations over the highland pastures in Kyrgyzstan to address five interrelated topics: (i) …

The Enbridge Line 3 Replacement Pipeline: Attitudes, Symbolism, And Geography, Catherine W. Fraser
Honors Theses
Oil pipelines, such as the Keystone XL and Dakota Access pipelines, are increasingly controversial and contested in the United States. Since its proposal in 2015, the Enbridge Line 3 Replacement (L3R) pipeline in Minnesota has also generated considerable debate. People who support and oppose oil pipeline projects are influenced by their ideologies, core values, partisan learnings, age, identity, and place attachment, as well as their proximity to new energy projects. However, the ability of any one variable, like spatial proximity or age, to predict attitudes towards new energy projects is debated. I conducted a literature review on attitudes towards energy …

African Savannah Elephant Group Size And Behavior In The Makgadikgadi Pans National Park, Botswana, Katherine S. King
African Savannah Elephant Group Size And Behavior In The Makgadikgadi Pans National Park, Botswana, Katherine S. King
Honors Theses
African savannah elephants (Loxodonta africana), the largest elephant species, influence the structure of the environment they inhabit. Elephants exhibit complex patterns of social behavior between individuals within a population. Many behavioral studies focus on interactions among individuals within a population rather than broader trends related to group size. My study seeks to understand how male African savannah elephant group size is influenced by seasonality, age, physical condition and distance to permanent water resources. I examined the interaction of these variables in two ways: (1) a literature review of elephant behavior and conservation, and (2) an analysis of male …
Developing A Predictive And Dynamic Moose-Vehicle Collisions Model In Maine, Yue Yu
Developing A Predictive And Dynamic Moose-Vehicle Collisions Model In Maine, Yue Yu
Honors Theses
Wildlife-vehicle collisions are a major form of human-wildlife conflict. Predictive animal-vehicle collision models have been developed to identify collision hotspots in Maine and guide mitigation strategies. However, most current models are static and unable to produce dynamic forecasts that incorporate changing climate and weather. The goal of my study was to develop a predictive and dynamic model of animal-vehicle collisions in Maine, USA. More than 6,700 moose-vehicle collisions (MVC) occurred from 2003 to 2017 in Maine, raising road safety, socio-economic, and wildlife conservation concerns. I sought to identify factors that contribute to a higher probability of MVCs by comparing two …
Factors Influencing Parental Care And Home Range Size Of A Monomorphic Species, The Red-Headed Woodpecker (Melanerpes Erythrocephalus), L. Abigail Walter
Factors Influencing Parental Care And Home Range Size Of A Monomorphic Species, The Red-Headed Woodpecker (Melanerpes Erythrocephalus), L. Abigail Walter
Theses and Dissertations
Parental care in animals can be costly and is shared between both parents in many bird species. Not surprisingly, most studies of how parental care is shared between the sexes are in sexually dimorphic species, and much less in known about sexually monomorphic species where sex cannot be determined in the field. This has prevented a full understanding of parental care behaviors – which are intrinsically linked to fitness – in species such as the Red-headed Woodpecker (Melanerpes erythrocephalus) that is experiencing population declines throughout much of its range. In this study we assessed whether Redheaded Woodpecker brooding time, nestling …

Belonging While Black At Lake Merritt: The Black Spatial Imaginary And Place-Making In Oakland, Ca, Betel Solomon Tesfamariam
Pomona Senior Theses
This thesis aims to demonstrate how the processes of gentrification and displacement are interrelated processes that invent new ways of perpetuating anti- blackness in the U.S. I demonstrate this through an engagement with Christina Sharpe’s (2016) analysis of the imagery of the wake, the ship, the hold, and the weather as axis points that position Black life in the afterlife of slavery—how the conditions of slavery are ongoing today—presenting the racist encounters at Lake Merritt as illustrative examples. In her most recent book, In the Wake: On Blackness and Being, Sharpe (2016) deploys an interdisciplinary approach to critically theorize …
