A Study Of Defensive Mechanisms Employed By Two Species Of Nudibranchs Using Toxicity And Unpalatability Analyses, Sean Youn
Independent Study Project (ISP) Collection
Nudibranchs are marine invertebrates that have developed an intriguing defense mechanism, including warning coloration and the use of chemicals accumulated through their sponge diet. The goal of this study was to determine whether the strength of chemical defenses differs between dietary and accumulated secondary metabolites for two species: Glossodoris vespa and Ceratosoma brevicaudatum. First, NMR spectroscopy was used to not only identify specific compounds in the mantle (outer covering) and the viscera (gut) but also to analyze the possibility of nudibranch species transporting more toxic compounds for defensive purposes. Next, toxicity (brine shrimp) and palatability (Palaemon shrimp) assays were used …
Solid Waste Management Of Disposable Diaper Sanitation And The Connection To Environmental Awareness For Women In Zanzibar, Micalea Leaska
Solid Waste Management Of Disposable Diaper Sanitation And The Connection To Environmental Awareness For Women In Zanzibar, Micalea Leaska
Independent Study Project (ISP) Collection
This project examined the solid waste management of disposable diapers in three locations, Stone Town, Mangapwani and Vikokotoni, within Zanzibar, Tanzania. Its methods included field observations of the solid waste disposal system in Zanzibar and interviews with women about their rationales for buying and using disposable diapers. For one of the first times, the data collected during this project will further assist to educate women about the benefits of cloth diapers and the negative effects disposable diapers create for Zanzibari families and the environment. This study has observed one of the most growing concerns regarding excess solid waste contributing to …
Multi-Sector Analysis Of The Progress And Challenges Of Soil-Transmitted Helminth Eradication In Rural Udaipur, Jessica Ellis
Multi-Sector Analysis Of The Progress And Challenges Of Soil-Transmitted Helminth Eradication In Rural Udaipur, Jessica Ellis
Independent Study Project (ISP) Collection
India is home to 240 million children currently at risk of Soil-Transmitted Helminthiasis, which is spread via unclean water, soil, and food, and causes acute pain and malnutrition. While acknowledging the research debates over WASH and mass drug administration, this study seeks to identify the systemic multidisciplinary issues affecting STH elimination efforts in rural Udaipur. Twenty-three interviews were conducted in villages, government departments, NGOs, and medical sectors to identify the challenges within each approach to deworming, and their experiences with multi-sectoral collaboration. The most recurring issues across disciplines were need for invested local leadership, increase in health literacy of adults, …
Fish Diversity And Coral Health Of Tanzania's Reefs: A Comparative Study Between The Ushongo Village Reef And The Fungu Zinga Reef Over Time, Della Turque, Corinne Casper
Fish Diversity And Coral Health Of Tanzania's Reefs: A Comparative Study Between The Ushongo Village Reef And The Fungu Zinga Reef Over Time, Della Turque, Corinne Casper
Independent Study Project (ISP) Collection
The world’s oceans are becoming increasing acidic due to global climate change, posing a threat to marine ecosystems, including coral carbonate systems. Environmental threats are exacerbated by human development stressors as well: growing populations, dependency on marine resources, and unsustainable practices invaluable marine ecosystems at risk. Tanzania’s coral reef system extends for 3580 km2 (Muhando et al. 2008) near the Tanga region, serving over half a million people who are highly dependent on fishing and other marine resources as their livelihoods (Samoilys et. al. 2008). With Tanzania’s population rapidly growing, the unsustainable pressure on coral reefs for sustenance and livelihood …
The Effects Of Sub-Lethal Predation On The Reproductive Output Of Acanthaster Planci (Crown-Of-Thorns Starfish), Emily Mucha
The Effects Of Sub-Lethal Predation On The Reproductive Output Of Acanthaster Planci (Crown-Of-Thorns Starfish), Emily Mucha
Independent Study Project (ISP) Collection
Wide-scale declines in live coral cover have been observed throughout history. Modern day coral populations face a multitude of environmental disturbances, however one of the most devastating to the reefs in the Indo-Pacific is the crown-of-thorns starfish (Acanthaster planci), which feeds on the tissues of live corals. The rate at which these individuals feed combined with the explosion of populations in times of outbreak have been seen to exert some of the biggest pressures on coral reefs to date. Following recent episodes of crown-of-thorns starfish (COTS) outbreaks, research on the organism has become increasingly prevalent on the scientific …
One Year Later: The Politics And Stories Of Post-Earthquake Nepal, Boyer Andrew
One Year Later: The Politics And Stories Of Post-Earthquake Nepal, Boyer Andrew
Independent Study Project (ISP) Collection
A 7.8 magnitude earthquake struck Nepal on April 25th, 2015. This was followed by a second major earthquake of magnitude 7.3 on May 12th , 2015. These disasters took the lives of thousands of Nepali people, destroyed hundreds of thousands of structures, and displaced an estimated two million people. Immediately following the disaster, there was an outpouring of humanitarian aid from around the world. This lead to a conference where $4.1 billion USD of reconstruction funds were pledged to Nepal by international donors. Five months later, a new constitution passed into law and an informal blockade of …
