An Assessment Of Icthyofauna And Artisanal Fishing From The Port Of Pedregal In The Golfo De Chiriquí., Kathleen A. Carey
Independent Study Project (ISP) Collection
The artisanal fishery based out of Pedregal, on the Pacific Coast of Panama in the Chiriqui Province was studied to analyze the biodiversity and community structure of the icthyofaunal population and investigate the practices and opinions of the fishermen there. The study area is located in the Gulf of Chiriqui, and is heavily influenced by freshwater runoff from anthropogenically influenced rivers during. This is especially relevant during the rainy season. During two weeks in November, at the end of the rainy season, fishermen from one port in Pedregal were accompanied for the purposes of data collection and interviewing. The data …
Animal Enrichment Strategies For Promoting Natural Behaviors In Captive Populations Of Tasmanian Devils (Sarcophilus Harrisii), Tierney O’Neal
Animal Enrichment Strategies For Promoting Natural Behaviors In Captive Populations Of Tasmanian Devils (Sarcophilus Harrisii), Tierney O’Neal
Independent Study Project (ISP) Collection
The population of Tasmanian devils (Sarcophilus harrisii) is in rapid decline due to Devil Facial Tumour Disease, and insurance populations have been created in captivity for potential future introduction into the wild. Many problems can arise within captive animal populations including loss of natural behaviors, and development of negative stereotypical (i.e. pacing) behaviors. These issues can decrease ecological fitness, potentially jeopardizing success of introductions of animals into the wild. By providing captive animals with enrichment, natural behaviors can be increased, and stereotypical behaviors can be decreased. Enrichment is defined as an activity or item that promotes the mental and physical …
A Study Of Sponge Aquaculture In Jambiani: Is Shallow Farming Feasible?, Sarah Friday
A Study Of Sponge Aquaculture In Jambiani: Is Shallow Farming Feasible?, Sarah Friday
Independent Study Project (ISP) Collection
In the village of Jambiani, Unguja, a Swiss NGO called Marine Cultures has established an experimental sponge farming initiative to improve local employment and support economic development. Currently, the main farming site is only accessible through SCUBA diving. This is consistent with experimental farm sites in other oceanic regions, as most are located in depths of at least five meters with sponges suspended vertically to maximize water flow exposure. Farms located in shallower water may not be conducive to sponge growth due to highly variable environmental conditions; however, no conclusive research has been conducted on this matter (Duckworth 2009). Nonetheless, …
What Is The Value Of A Sea Turtle?: A Case Study Of The Conservation Ethics Of Sea Turtle Fishermen In The Caribbean Coast Of Nicaragua, Alicia Conte
Independent Study Project (ISP) Collection
The sea turtle populations on the Caribbean Coast of Nicaragua have dramatically decreased as a result of human use and consumption. All species of sea turtles are endangered and at risk of extinction. This is an environmental issue because if sea turtles go extinct, many other plants and animals in marine ecosystems will be negatively impacted by this loss, and the environment will be drastically altered. This is also problematic for locals who depend on this resource for food and as a source of income. Conservation efforts have been initiated by an international NGO, the Wildlife Conservation Society (WCS); however, …
Nomadic Knowledge Of The Yak: A Case Study In The Khangai Mountains, Mongolia, Jesse Geary
Nomadic Knowledge Of The Yak: A Case Study In The Khangai Mountains, Mongolia, Jesse Geary
Independent Study Project (ISP) Collection
It is extremely important to probe and preserve the knowledge of nomadic herders of Mongolia. There is no formal piece of literature that dictates how these clever humans survive. Their lifestyle requires a vast skill set spanning from construction knowledge, to navigational skills, to a deep understanding of their animals. One attains this knowledge through years of observation, listening, and attempting to mimic their parents. In this way, knowledge is passed on from one generation to the next. Investigating herder’s knowledge of the yak provides a window into the animal husbandry practices of Mongolian nomads. The herders in the central …
Monitoring Nesting Trends And Hatchling Success Of The Green Turtle (Chelonia Mydas) Population On Mnemba Island, Zanzibar, Taylor Dunbar
Monitoring Nesting Trends And Hatchling Success Of The Green Turtle (Chelonia Mydas) Population On Mnemba Island, Zanzibar, Taylor Dunbar
Independent Study Project (ISP) Collection
The nesting trends and hatching success of Green sea turtles (Chelonia mydas) were studied on Mnemba Island. This study involved a continuation of data collection for the ongoing monitoring program of sea turtles on Mnemba Island. Data was collected from nesting females as well as from post hatching nest excavations. The data that has been collected over the course of ten years was then analyzed to examine trends over time as well as to assess the current status of the turtle population on Mnemba Island. Hatch success as a function of different seasons was analyzed. It has been concluded that …
Predators Of Enashiva: A Survey Of Occurrence & Distribution, Adrienne Fisk Bowles
Predators Of Enashiva: A Survey Of Occurrence & Distribution, Adrienne Fisk Bowles
Independent Study Project (ISP) Collection
This study was conducted during a period of 16 days (April 10 to April 26, 2011) at the Enashiva Nature Refuge in Northern Tanzania. It was a modified repeat study, using the same methodologies of a mammal survey conducted in November 2009, however this study only focused on occurrence and distribution of predators in the highest trophic level and accounted for reptile and birds, in addition to mammals. Based upon the findings of the November 2009 study, it was hypothesized that the woodland would have the highest predator species richness. This hypothesis was supported by the data; the woodland habitat …
A Habitat And Abundance Study Of Octopus Cyanea In Southwest Madagascar, Michael Belazis
A Habitat And Abundance Study Of Octopus Cyanea In Southwest Madagascar, Michael Belazis
Independent Study Project (ISP) Collection
The increased demand for marine products has fueled a worldwide overexpansion of the fishing industry. Furthermore, the shift of lower-income countries, like Madagascar, from subsistence to market-based cash economies has led to increased fishing pressures on marine resources. Recent commercialization of fisheries in Southwest Madagascar has caused an over-exploitation of octopus in the Toliara region. In an effort to create sustainable octopus fisheries, Blue Ventures, a UK-based NGO, created the world’s first community run Marine Protected Area (MPA) for octopus near Andavadoaka called Velondriake.
Here, the results of an Octopus cyanea habitat study performed near Beheloke, a fishing village on …
Examining Trends In Taste Preferences, Market Demand, And Annual Catch In An Indigenous Marine Turtle Fishery In Southwest Madagascar, Kristin Jones
Examining Trends In Taste Preferences, Market Demand, And Annual Catch In An Indigenous Marine Turtle Fishery In Southwest Madagascar, Kristin Jones
Independent Study Project (ISP) Collection
The worldwide exploitation of marine turtles has been common throughout human history, turtle products including carapaces for decoration and use, skin for leather, and eggs and meat for consumption. The hunting of marine turtles has long established economic importance among Madagascar's coastal inhabitants and is an activity traditionally associated with integral cultural and spiritual values. Due to overexploitation and a combination of relatively newer threats such as pollution, habitat loss, and incidental fisheries take, however, all marine turtle species in the Indian Ocean are considered to be endangered or critically endangered. Although Madagascar's marine turtles have been legally protected from …
Adult Female Activity Time Budgets In Red-Bellied Lemurs (Eulemur Rubriventer) And Infant Survival: Ranomafana National Park, Frances Hardy
Adult Female Activity Time Budgets In Red-Bellied Lemurs (Eulemur Rubriventer) And Infant Survival: Ranomafana National Park, Frances Hardy
Independent Study Project (ISP) Collection
My research during the independent study period focuses on the relationship between activity time budgets of adult female red-bellied lemurs (Eulemur rubriventer) and infant survival. I conducted my research under the guidance of Centre ValBio in Ranomafana National Park. Red-bellied lemurs have a clear three month birth peak from Aug-Oct, but up to 30% of infants in a single year can be born outside of this birth peak, however, survival for out-of-season infants is strikingly low compared to in-season infants, 100% (n=4) of out-of-season infants died in one study conducted in 2009, whereas only 11% (n=18) of in-season …
