Prey Naïveté And Predator-Prey Interactions Between Pterois Volitans, Pomacentridae, And Tetraodontidae In Two Reefs In The Guna Yala Archipelago, Panama, Jesse Garrett-Larsen
Prey Naïveté And Predator-Prey Interactions Between Pterois Volitans, Pomacentridae, And Tetraodontidae In Two Reefs In The Guna Yala Archipelago, Panama, Jesse Garrett-Larsen
Independent Study Project (ISP) Collection
The invasion of Pterois volitans along the Atlantic coast of the Americas is one of the top marine conservation issues of the century. Prey naïveté has been suggested as a mechanism for the success of P. volitans, but conclusive field observations have not been completed. This study tested for prey naïveté in situ by comparing time spent by Pomacentridae and Tetraodontidae in close proximity to P. volitans and a native predator, Cephalopholis cruentata. Difference in time spent by Pomacentridae and Tetraodontidae in the presence of the two predators was observed. The predators P. volitans and C. cruentata were sequentially observed …
Fish Community Assessment Of The Bonyic And Teribe Rivers Within The Naso-Teribe Territory Bocas Del Toro, Panama: Possible Implications Of Bonyic Dam., Shaylyn Austin
Independent Study Project (ISP) Collection
In the Changuinola/Teribe watershed of Bocas Del Toro, Panama, changes to the fluvial system due to the recently constructed Bonyic Dam have implications connected to the biodiversity of a UNESCO Biosphere Reserve and the livelihoods of thousands of people of the Naso-Teribe indigenous group. This study investigated the composition of fish communities in 6 study sites in 3 different areas in relation to the Bonyic Dam. A total of 318 individual fish were captured, representing 5 families and 10 species, using the cast net sampling method. The biodiversity was analyzed using Simpson’s Diversity Index, Evenness Index, species richness, and species …
Development Of A Wild Infant Woolly Monkey Social Interactions, Time Allocation And Behavior Of A Wild Lagothrix Lagotricha Poeppigii Infant And Her Mother, Saba Zewdie
Independent Study Project (ISP) Collection
The lowland woolly monkey (Lagothrix lagotricha poeppigii), like all species of woolly monkey, is extremely threatened due to anthropologic activities such as deforestation, petroleum drilling and commercial hunting across their habitat. Due to their low reproductive rate and low reproductive success in captivity, the captive population is decreasing every year as habitat loss increases. In late February of 2017 an infant female was born on the island of Sumak Allpa, a monkey rehabilitation organization and reserve in the western Ecuadorian Amazon. The woolly monkeys are completely independent on the reserve; and as such her birth marks the first …
Reef Fish And Coral Assemblages On Hospital Point And Near Bastimentos Island, Panama, Elaine Shen
Reef Fish And Coral Assemblages On Hospital Point And Near Bastimentos Island, Panama, Elaine Shen
Independent Study Project (ISP) Collection
Because worldwide declines coral reef health are of major concern, studying coral reefs through the lens of conservation efforts at local scales is essential for determining and monitoring effective policy measures. In the Bocas del Toro Archipelago, there are conflicts of interest between exploitative rapid tourism development, overfishing practices, and national efforts to conserve the local marine biodiversity. Coral and reef fish species abundance richness, diversity, evenness, and similarity were measured to see how coral and reef fish assemblages changed between protected and unprotected areas. A total of 329 fish and 322.5 square meters of benthos were analyzed using underwater …
Marine Animalia Organism Diversity And Reef Condition On Two Reef Sites At Big Creek Beach And Boca Del Drago, Bocas Del Toro, Panamá, Bri Tiffany
Independent Study Project (ISP) Collection
Ocean acidification, climate change, overfishing, and coastal development are endangering coral reefs across the globe. In Bocas del Toro, Panamá, coral reefs are especially threatened by the rapid growth in tourism and the subsequent anthropogenic effects caused by an increased human presence. To evaluate reef condition in this area, a study comparing percent coverage of live and dead coral as well as the diversity of marine Animalia organisms was conducted at one reef site in Big Creek beach and one reef site in Boca del Drago, Isla Colón, Bocas del Toro. It was predicted that dead coral cover would be …

A total of 99 interviews were conducted. Over a period of 28 days from April 5- May 2, 2015, a total of 75 interviews were conducted with 72 fishermen, 2 drying processors and 1 Bwana Diko. During a 5 day preliminary period from March 12-16, 2015, a total of 24 interviews were conducted with 7 fishermen and 14 drying processors. The interviews focused on their work in the local fishing industry, the amount of fish caught and dried, and their opinions on the sustainability of their industry. The interviews were conducted using a translator who relayed the responses in English …
