Effects Of Ocean Acidification On The Behavior Of Two Marine Invertebrates: A Study Of Predator-Prey Responses Of The Molluscs Conus Marmoreus And Strombus Luhuanus At Elevated-Co2 Conditions, Jennifer Fields
Independent Study Project (ISP) Collection
Ocean acidification has been affecting the world’s oceans since the introduction of anthropogenic CO2 into the atmosphere during the Industrial Revolution. An increase in CO2 uptake from the atmosphere to the ocean has had a profound impact on not only the water chemistry, but marine organisms as well. Ocean acidification is known to have significant impacts on marine invertebrates in terms of calcification and reproduction; however, effects of increased CO2 on marine invertebrate behavior are vastly unknown. Marine conch gastropods have a modified muscularized foot that allows them to escape quite rapidly when faced with a predator cone shell. Utilizing …

Mongolian National Parks: Competing Interests And Institutional Viability In A Still Emerging Protected Areas System, Kieryn Wurts
Independent Study Project (ISP) Collection
In Mongolia, 17% of the total landmass is designated as one of four kinds of “protected areas”—Strictly protected areas, national parks, nature reserves, and natural historical monuments. This study focuses primarily on national parks as a civil institution, through on the ground interviewing of ten individuals employed in the protected areas system, field-notes and observations, and community surveying totaling 38 respondents at two research locations, Hustai-Nuruu National Park and Lake Khovsgol National Park. Protected areas are constructed civil spaces, and as a result are sites of competing societal interests--the interests of scientists and conservationists, of tourism and business interests, and …
Carbon Can’T Buy Happiness: An Analysis Of Ecological Footprints And Happiness Of University Students In The City Of David, Panama, Samantha Burlager
Carbon Can’T Buy Happiness: An Analysis Of Ecological Footprints And Happiness Of University Students In The City Of David, Panama, Samantha Burlager
Independent Study Project (ISP) Collection
Global climate change is perhaps the most pressing issue our world faces today. Greenhouse gas emissions reductions are urgently needed, however, there is currently a lack of action due to the fear that a reduction in the ecological footprint will lead to a reduction in GDP and happiness levels of a society. Increasing GDP and economic progress are equivocated with increasing happiness and overall well-being of society. However, based on the literature I discuss in this paper, instead of GDP, an objective measurement of happiness is a better indicator of success. In this paper, I investigate the ecological footprints (in …

Analysis Of Mitochondrial Dna Structuring Between Colonies Of The World’S Smallest Penguin (Eudyptula Minor) In New South Wales, Australia, Melissa R. Tighe
Independent Study Project (ISP) Collection
The Little Penguin, Eudyptula minor, is a flightless seabird that is endemic to Australia and New Zealand. It can be found nesting on both on and offshore colonies along the coasts of both countries and it is the only penguin currently found breeding on mainland Australia. The IUCN Red List of Threatened Species lists E. minor as “Least Concerned,” but numbers have noticeably dropped in recorded history due to a number of direct and indirect anthropogenic influences. One particular location of decline is Manly, New South Wales that contains the last onshore breeding colony of E. minor in NSW, Australia. …

Implications For Soil Microbe Research: Investigations Into The Feasibility Of Dna Amplification From Stained Roots And Temporal Patterns In Arbuscular Mycorrhizal Fungal Communities., Catherine Ausland
Independent Study Project (ISP) Collection
Arbuscular mycorrhizal (AM) fungi are obligate biotrophs that form symbiotic relationships with 80% of vascular plants around the world. Because of their beneficial relationship with plants in almost all terrestrial ecosystems, the implication of utilizing AM fungi in ecological restorations is immense. The following investigations seek to increase knowledge of the community ecology of AM fungi in order to enhance the potential for use of AM in ecological restoration. The first investigation replicated a novel method of AM visualization in plant roots, utilizing ink and vinegar as less destructive staining agents, to determine whether molecular studies could be feasibly performed …
