Identification Of Antibiotic Ge37468a From Pseudonocardia Symbionts Of Trachymyrmex Septentrionalis Ants, Krithika Rao
Identification Of Antibiotic Ge37468a From Pseudonocardia Symbionts Of Trachymyrmex Septentrionalis Ants, Krithika Rao
Scripps Senior Theses
In response to the growing rates of antibiotic resistance in human bacterial pathogens, this study explores the natural products involved in the defensive symbiosis between actinobacteria and fungus-growing ants to uncover new potential antibiotics. This study also seeks to understand the function of natural antibiotics in their ecological contexts, especially those involved in defensive symbioses. Defensive symbiosis can be a beneficial platform for discovering useful antibiotics, because antibiotics in these relationships must be able to selectively inhibit enemies without harming hosts, and are therefore likely more specific and less toxic. Pseudonocardia sp. associated with Trachymyrmex septentrionalis ants demonstrated antibiotic activity …
Role Of Managed Marine Areas On The Diversity And Individual Responses Of Rocky Intertidal Shore Grazers In Central Chile, Kathy Liu
Scripps Senior Theses
Many different types of marine benthic herbivores or “grazers” inhabit coastal intertidal zones and play a crucial role in inter- and shallow subtidal ecosystems. Chile has one of the most diverse intertidal zones, but many intertidal grazers are exploited for human consumption. Marine protected areas (MPAs) and marine management and exploitation areas (MEAs) are promising tools for Chile to combat over exploitation of these grazer and other marine resources. This study surveyed the impact of sites with contrasting management on the diversity and abundance of all intertidal grazers and their impact on the size frequency and shell length-body weight allometry …
