Blooming Mountains Of Biodiversity: An Investigation Of Angiosperms On Cerro Mayordomo, Tungurahua, Ecuador, Ella Matsuda
Independent Study Project (ISP) Collection
Ecuador is one of the most biodiverse places on the planet, and many of the species in the region are found nowhere else in the world. The cloud forest is particularly diverse because the mountainous terrain isolates populations and changes in elevation create a wide variety of habitats. Cerro Mayordomo is a relatively unexplored mountain in the cloud forest of Tungurahua, Ecuador. It is known to have very high levels of endemism and several new species have been discovered there, but the biodiversity of angiosperms on the mountain has never been quantified. In this study, 5x5 m quadrants were established …

The Development Of A Reproductive Population Of Chorongos: Intergroup Interactions, Dispersal, And Sexual Behavior Of Lagothrix Lagotricha Poeppigii In Natural Rehabilitation On The Island Of Sumak Allpa, Ecuador, Rachel Gallegos
Independent Study Project (ISP) Collection
The lowland woolly monkey (Lagothrix lagotricha poeppigii) is vulnerable due to various human pressures, as they are especially sensitive to stress and habitat degradation. Due to their low rate of success in captivity, the few institutions that have tried to create and maintain breeding populations for conservation purposes are no longer able or willing to do so. Sumak Allpa, an NGO in the Orellana province of the Ecuadorian Amazon, currently has the only repopulation project in Ecuador with the long-term goal of maintaining a reproductive population and releasing groups of woolly monkeys back into the wild. In a …

Managing Devil Facial Tumour Disease In Tasmanian Devils (Sarcophilus Harrisii): An Investigation Of Heat Shock Proteins As Potential Vaccine Adjuvants, Monika Payerhin
Independent Study Project (ISP) Collection
The world’s largest carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii), is facing extinction from a deadly, highly communicable cancer that has already decimated over 85% of devil populations in the wild: devil facial tumour disease (DFTD). DFTD cells effectively evade recognition by the immune system, and every devil that contracts the disease dies from it. Many attempts have been made at developing a vaccine that could help save this now-threatened species. Heat shock proteins have been linked to enhanced immune recognition of pathogens, making them potential candidates for acting as adjuvants to such a vaccine against DFTD. In this study, …
