Variability In Antibacterial Activity In The Caribbean Sponge Amphimedon Compressa, Mackenzie Reilly
Honors Theses
Coral reefs are essential ecosystems that provide an abundance of natural resources. Sponges, common reef inhabitants, produce a diversity of secondary metabolites that are known to serve as chemical defenses. Secondary metabolites often have ecological functions, such as antipredator and antibacterial activities. I studied the common Caribbean sponge species, Amphimedon compressa, which is known to be chemically defended. Samples were collected from three sites in Belize, two sites in Grand Cayman, and three sites in St. Croix, U.S. Virgin Islands. To determine whether antibacterial activity varied across broad or local geographic scales, sponge extracts were tested against four bacterial strains …
