Corallivorous Reef Fishes As Potential Vectors Of Coral Disease Based On A Study Of Dietary Preferences, Tanya Rogers
Independent Study Project (ISP) Collection
The prevalence of coral disease appears to be increasing worldwide, although little is known about how these diseases are transmitted between coral colonies. To examine whether corallivorous fishes could potentially act as disease vectors, this study examined whether and which fish species feed on diseased coral, and whether these fishes actively target diseased coral sections. Branches of Acropora muricata with brown band disease were filmed in the field, and bites taken by fishes on different sections of the coral (live tissue, tissue margin, disease band, dead skeleton, and algae) were recorded. For each fish species, electivity indices were calculated for …

Calidad Química Y Microbiológica Del Agua Y Acceso Al Recurso Agua En La Comunidad De Solöng, Territorio Naso-Teribe, Bocas Del Toro, Shira Wrightman
Independent Study Project (ISP) Collection
This study evaluated the water quality and accessibility of water resources in the community of Solöng located in the Naso-Teribe territory of the province of Bocas Del Toro. The seven chemical parameters of nitrate, phosphate, pH, alkalinity, total hardness, turbidity and dissolved oxygen were used to assess the safety of drinking water and the health of aquatic ecosystems utilized by the residents of Solöng. A microbiological assessment which included tests for total coliform bacteria and the fecal coliform strain group of Escherichia coli were conducted as well. Chemical tests were performed in a total of 15 spigots, 7 streams, 2 …
