Effect Of Varied Macronutrient Ratios On Honey Bee Tolerance To Iapv Infection, Caitlin Lennon-Puthoff, Alex Payne, Adam Dolezal Apr 2023

Effect Of Varied Macronutrient Ratios On Honey Bee Tolerance To Iapv Infection, Caitlin Lennon-Puthoff, Alex Payne, Adam Dolezal

PRECS student projects

Honey bees are killed by Israeli acute paralysis virus (IAPV). Because this virus has no cure, it is important to lessen its impact on bees through proper nutrition. This project explores the effects of differing protein to lipid (P:L) ratios in pollen on honey bee susceptibility to this virus.

Over three trials, bees in cages were incubated for 3 days to resemble hive conditions. Two doses of IAPV (10-3 & 10-2) and a negative control were used, along with five P:L ratios (1.5, 2.5, 11.5, 16.5, & 21.5:1) and a sucrose-only diet. These treatment groups were combined …

Graduate, 2nd Place: Assessing The Knowledge, Attitude, And Everyday Life Practices Adopted Among Eastern Illinois University Students Towards Sustainability, Joel Holison

2023 Awards for Excellence in Student Research and Creative Activity - Documents

The concept of sustainable development gained attention and came into focus with the publication of the Brundtland Report (Brundtland, 1987). later the Education for Sustainability (EfS) initiative was presented in 1997 through the “Thessaloniki Declaration” as a carrier of the common and single message (Knapp, 2000). Sustainable development is the way a country pursues its economic development that does not jeopardize the opportunity for future generations to achieve their development (Brundtland, 1987). Deforestation, land destruction, soil degradation, air and water pollution, and other types of environmental deterioration are paid in the name of economic progress. This detriment may outweigh the …

Consumers And Eco-Labels: A Quantitative Analysis Of The Effects Of Various Sustainability Certification Models On Consumer Opinions, William F. Joseph Apr 2023

Consumers And Eco-Labels: A Quantitative Analysis Of The Effects Of Various Sustainability Certification Models On Consumer Opinions, William F. Joseph

Senior Theses

This research consists of an econometric analysis of the efficacy of a privatized sustainability certification model versus a proposed government-endorsed sustainability certification model within the United Sates market. Today, the widely accepted model of sustainability certification is constituted by a large market of private certifiers. By analyzing the effects of the current model and alongside the effects of a hypothetical government-endorsed system on consumer preferences for sustainably produced goods, the thesis aims to motivate further discussion into the possible benefit of adopting a government-sponsored sustainability certification system. In general, analysis of the data suggests much more promising and significant effects …

Tourism, Mapping, Retail And Recreational Trails: A Case Study Of Connectivity Between Trails And Adjacent Downtowns In Anniston, Alabama, Usa, Jennifer Green

Theses

This study examines the estimated increase in economic impact on a geography’s local economy by creating cross-marketing efforts between expanding an established outdoor recreation trail to a closely located city downtown commerce district. This research will analyze the resulting potential rise in sales/lodging tax revenues for that city by mapping the trail and downtown district, and cross-marketing the other to users of both or either venue. Potential increase in economic impact will be estimated utilizing IMPLAN methodology by assessing the economic impact on the local economy that a percentage range of increased spending resulting from this cross-marketing effort could generate.


Role Of Age And Sex In The Effects Of Repeated Methamphetamine Exposure On Hedonic Tone In Sprague Dawley Rats, Cameron Lewis, Conor Strumberger, Joshua M. Gulley Apr 2023

Role Of Age And Sex In The Effects Of Repeated Methamphetamine Exposure On Hedonic Tone In Sprague Dawley Rats, Cameron Lewis, Conor Strumberger, Joshua M. Gulley

PRECS student projects

Anhedonia is defined as a reduced or complete loss of pleasure from a previously pleasurable stimulus, and it is comprised of two dimensions:

  • Hedonic anhedonia consists of a distinct loss of pleasure in consumption of a normally pleasurable stimulus.
  • Motivational anhedonia involves the goal directed behavior to obtain a reward.

Withdrawal induced anhedonia following use of methamphetamine (METH) is thought to contribute to relapse behaviors1,2 . The anhedonic effects of drug withdrawal largely depend on dose, frequency, and the duration of drug exposure4,5,6.

The role of sex and age of exposure in this context has yet to …


A Comparative Life Cycle Assessment Of Cork Versus Traditional Shoe Insole Material, Alexandra Lum Apr 2023

A Comparative Life Cycle Assessment Of Cork Versus Traditional Shoe Insole Material, Alexandra Lum

Independent Study Project (ISP) Collection

Shoes are conventionally produced from materials like plastic or rubber that have detrimental impacts on the environment such as exacerbating existing waste accumulation, increasing global amounts of greenhouse gasses, or releasing toxic chemicals into soils and groundwater. These impacts have pushed footwear companies to introduce more sustainable and ecologically-friendly materials in their products. Roughly half of all cork production occurs in Portugal. The present work employs a comparative life cycle assessment approach between traditional plastic and rubber insole material and cork insole material to investigate the environmental impact of each. Results show that during each stage of the insole life …


Wishing For Water While Fleeing Their Farms: A Study Of Water Scarcity And Internal Migration In Tunisia, Tyler Rak Apr 2023

Wishing For Water While Fleeing Their Farms: A Study Of Water Scarcity And Internal Migration In Tunisia, Tyler Rak

Independent Study Project (ISP) Collection

How does water scarcity and limited water access impact internal migration? I argue that water scarcity and limited access to water is likely to increase internal migration in Tunisia. The mechanism through which I will investigate this relationship is in the agricultural sector. In this research, I found that water scarcity does exist in Tunisia and that scarcity impacts the economy, employment, and perceptions of rural areas in Tunisia. This, in turn, likely contributes to internal migration, although my research could not conclude whether water scarcity acts a causative factor to internal migration. This topic has become more prevalent than …

Variation In The Growth Parameters And Biomass Of Rhizophora Mangle Seedlings With Distances From Playa Estrella, Bocas Del Toro, Panama, Thiny Tep

Independent Study Project (ISP) Collection

Mangrove is a salt-tolerant, intertidal, tropical tree or shrub and make up a rich community of various organism. On the Caribbean coast of Panama, in Bocas del Toro, mangrove forests cover 28 km2 and are dominated by R. mangle, followed by L. racemosa and A. germinans. Simultaneously, Isla Colón, the most populated and developed among all islands in the Bocas del Toro Archipelago, is a tourist center. Unfortunately, tourism comes at the price of environmental degradation via alteration of natural habitats, solid and wastewater pollution. Therefore, this study aims to gain a preliminary understanding on how the …


Rocky Intertidal Community Structure Along An Upwelling Gradient Between Playa Venao And Nueva Gorgona On Panama’S Pacific Coast, Claire Brady Apr 2023

Rocky Intertidal Community Structure Along An Upwelling Gradient Between Playa Venao And Nueva Gorgona On Panama’S Pacific Coast, Claire Brady

Independent Study Project (ISP) Collection

Ecological research on rocky intertidal ecosystems has increasingly focused on the regional oceanographic processes that shape community structure over functional group interactions. Intertidal communities’ dependence on onshore and offshore transport of intertidal species larvae, dissolved inorganic nutrients, and phytoplankton signal that upwelling and nearshore currents can have an influential role in determining the growth and composition of intertidal systems. The community structure of rocky intertidal areas was compared between two locations along an upwelling gradient in the Gulf of Panama: Nueva Gorgona, with intermittent seasonal upwelling, and Playa Venao, with fringe seasonal upwelling. The surface cover of algae, barnacles, and …

Troop Composition And Behavior Of Mantled Howler Monkeys (Alouatta Palliata) In Mangroves And Forested Islands South Of David, Panama, Slate Hyacinthe

Independent Study Project (ISP) Collection

The mantled howler monkey, Alouatta palliata, is one of the most commonly studied and widely distributed primate species in Central America. They have been reported to inhabit mangrove environments in Panama, but few studies have undertaken to describe their demography and behavior in these particular ecosystems. For my study, I spent 12 days studying A. palliata populations in both the mangrove and forested island ecosystems (Isla Parida and Isla Boca Brava) south of David. Seven groups were found in the mangrove environments, and 11 groups were found on the island environments. The mangrove groups were significantly smaller and at a …


Understanding Invasive Predation: Detections Of Feral Cats (Felis Catus) On Kangaroo Island’S Western River Refuge, Leah Boget Apr 2023

Understanding Invasive Predation: Detections Of Feral Cats (Felis Catus) On Kangaroo Island’S Western River Refuge, Leah Boget

Independent Study Project (ISP) Collection

Feral cats (Felis catus) are a priority-level threat for small to medium-sized native vertebrates across Australia and especially so in insular environments like that of Kangaroo Island, South Australia. The island is home to several endangered and geographically restricted species, including the Kangaroo Island Dunnart (Sminthopsis aitkeni), an endangered marsupial endemic to Kangaroo Island. When bushfires spread across the island and burned x percent of native vegetation in late 2019 to early 2020, these populations were critically impacted and post-fire feral cat predation on the island risked their extinctions, motivating the creation of a refuge with …


Coastal Morphology And Sediment Deposition On Adjacent Coral Reefs At Misali Island, Sophia Rosati Apr 2023

Coastal Morphology And Sediment Deposition On Adjacent Coral Reefs At Misali Island, Sophia Rosati

Independent Study Project (ISP) Collection

Terrestrial and marine ecosystems are frequently interpreted under separate lenses. On a 1 km wide island, however, these two sciences are inextricably tied. Misali Island, a small coralline island in the Indian Ocean, has been largely uninhabited for its entire history, making this coastal interface unique. In this study, Misali Island is used as a study region to demonstrate how natural processes are materializing in the Zanzibar Archipelago. Methods employed, both geological and marine, work to understand the erosional circumstances of Baobab Beach and the inherent effects on local coral reefs. Results show that Misali’s northeastern beachfront is currently under …

Water Resources Professional Project Reports

Rapid advances in technology, especially smart phones, have changed citizen science around the world. Citizen science-generated data are growing exponentially, so there is increasing interest about what is happening with all this data. Some research suggests that governmental agencies are not using citizen science data to make ecosystem management decisions, although other studies contradict this finding. Regionally, the Middle Rio Grande bosque ecosystem extends for 162 miles along the Rio Grande in New Mexico. The Bosque Ecosystem Monitoring Program, or BEMP, was founded in 1996 following the efforts of the Bosque Initiative and the development of the Bosque Biological Management …


Performance Of The Mineral Recovery Enhanced Desalination Pilot Water Treatment Plant, Samantha Valentine Apr 2023

Performance Of The Mineral Recovery Enhanced Desalination Pilot Water Treatment Plant, Samantha Valentine

Water Resources Professional Project Reports

There is a growing interest in treating brackish groundwater to supplement freshwater resources for inland communities in arid climates. Water recovery by desalination of brackish groundwater is challenging due to mineral scaling from ions which form carbonate and sulfate minerals, dissolved silica which forms silicates, iron, manganese, and other constituents along with the difficulties and cost of disposing of large volumes of brine from the desalination process. The MRED process consists of a pretreatment process to increase water recovery and decrease waste production from brackish groundwater. The MRED process uses a unique sequence of unit processes consisting of: (1) Air …


Rural Water Manager Challenges In New Mexico, Amy "Aj" Jones Apr 2023

Rural Water Manager Challenges In New Mexico, Amy "Aj" Jones

Water Resources Professional Project Reports

New Mexico poses a valuable set of circumstances to study the challenges faced by drinking water systems. A general lack of resources for small systems, be it personnel and funding issues, lack of community engagement, lack or loss of institutional knowledge, ability to meet regulations, and aging managers were found to be very common and widespread. Rural water manager positions that are unsupported financially do not assist in alleviating rural poverty or draw the workforce. Therefore, the negative state demographic statistics are reinforced, further complicating rural water management rather than helping the issues. To look at drinking water management comprehensively, …


Securing Environmental Flows For The Rio Grande Silvery Minnow, Ashley Veihl Apr 2023

Securing Environmental Flows For The Rio Grande Silvery Minnow, Ashley Veihl

Water Resources Professional Project Reports

Since 1997, the Bureau of Reclamation (Bureau) has been leasing water to provide habitat for the now-endangered Rio Grande silvery minnow (Minnow). The majority of leased water comes from the San-Juan Chama project, a trans-basin water delivery system that was originally implemented to secure flows to the Rio Grande for municipal and agricultural use. Limitations on water storage within reservoirs incentivize contractors that are allocated more surface water than they can use to lease the extra quantity. It is through this water leasing market that the Bureau has established the largest environmental flow program in the state of New Mexico. …
