The Value Of Chemical Defense: The Effects Of Toxin Milking On The Physical, Physiological, And Behavioral Performance Of Cane Toads (Rhinella Marina), Ryann Blennerhassett

Independent Study Project (ISP) Collection

Amphibians have cutaneous glands on their skin which produce a number of toxic compounds that serve as protection against predators and microorganisms. Cane toads (Rhinella marina) have large parotoid glands located on their shoulders to store toxins, many of which are derived from lipids and are thus energetically expensive to produce. I used a combination of field and laboratory studies to investigate behavioral and physiological consequences of toxin loss and replenishment in cane toads. In a cross-sectional study, free-ranging toads were euthanized and dissected to identify correlations between toxin content and morphology /physiology. Experimental manipulations (manually expressing toxin from glands) …

An Overview Of Psychological Barriers To Climate Change Response And Their Implications For Improved Climate Change Communication, Ari Katz

Independent Study Project (ISP) Collection

As climate change becomes an increasingly devastating issue it seems as if concern dwindles just as severely. Climate change lends itself so readily to apathy, but why? The overarching goal of this paper is to figure out the answer to a seemingly simple question: why do people have such a difficult time understanding and acting on climate change? The process of answering this question is a bit more complicated, and for the scope of this paper, the process is twofold. First, I aim to uncover the psychological barriers that prevent climate change response. Discussion of these psychological barriers includes insights …

Getting Sick Where Karma Is Gravity: Disease In The Tibetan Perspective, Moreau Hadley

Independent Study Project (ISP) Collection

Karma is the Buddhist idea that our actions from current and previous lives affect our fortune in this life. In particular, if we suffer in the current life, it is due to negative action in the past. Likewise, if we prosper, it is due to past positive acts, such as compassion. The idea of karma extends to illness; in simplification, sickness is attributed to negative past action.

The purpose of this study was to investigate the belief of karmic disease in the Tibetan Buddhist community of Shangri-La. Although disease is often used as an example of karmic suffering, and there …

Legacies Of War: How The Commercialization Of Plastics In The United States Contribute To Cycles Of Violence, Karis Johnston

Capstone Collection

Plastic manufacturing practices developed and justified during World War II transitioned into the commercial space, entered our homes, and became part of everyday life. This proliferation was due in large part to the consolidation of manufacturing processes organized and subsidized by government contracts and the plastics industry leaders’ marketing dynamism. Plastics are in the cars we drive, the way we package our food, and are invaluable throughout the medical field. Moreover, the use of plastics has tangible environmental and health ramifications.

Coral Species Distribution And Percent Cover Of Sessile Organisms On Protected And Non-Protected Coral Reefs In Digir, Buga, Dubbir, And Kanir Kinnidup, Guna Yala, Panama, Sarah Paulson

Independent Study Project (ISP) Collection

Coral reefs are the most productive, biodiverse ecosystems in the ocean despite covering only <.5% of the ocean floor. In today’s changing climate, coral reefs face a multitude of threats including ocean warming, coral bleaching, ocean acidification, overfishing, increasing human population, and coral mining, among others. One way to protect coral reefs is to establish a marine protected area to limit damage and contamination. This study aimed to examine coral species distribution as well as percent cover of sessile organisms and substrates including coral, fire coral, algae, and sponges on protected and non-protected reefs in order to attempt to analyze the effect of protection on coral reefs in Guna Yala, Panama. Based on the data collected, protected areas had higher algae cover (P<.01, df=107), lower coral cover (P<.0001, df=138), and a higher relative abundance of corals with a “weedy” life history such as Porites astreoides (P<.05, df=80). The data also showed that uninhabited islands tended to have significantly higher average coral cover (P<.0001, df=146) and lower average algae cover (P<.0001, df=161), as well as lower relative abundance of P. astreoides (P<.01, df=134). When the protected site sampled was compared to an unprotected site that was around the same island, the protected area was found to have higher coral cover (P<.01, df=71) and lower algae cover (P<.05, df=72) than the unprotected area. Ultimately, lack of human population and protected status were found to be positive factors for coral reef health, and future study should be done to further examine the relationship between these two factors.
