Fragile Oceans, Synthetic Flotsam And Microbial Collaboration – Explorations In The Visual Communication Of The Plastic Crisis, Ivan Langesfeld
Fragile Oceans, Synthetic Flotsam And Microbial Collaboration – Explorations In The Visual Communication Of The Plastic Crisis, Ivan Langesfeld
Pomona Senior Theses
Scientific evidence that the ocean plastic crisis is larger in scale and more sinister than previously thought continues to mount, but the rate of plastic production is only rising. What will it take to decisively turn the tide against plastic? We need scientists, politicians, and industry changemakers to continue producing knowledge and positive change in the industry, but we need to go further still. This thesis explores art as an alternative visual communication strategy with the capacity to encourage curiosity, empathy, and positive engagement with the issue of ocean plastics. The series of work explores bacterial bioluminescence as an artistic …

Experimental evolution is relevant to ecology because it can connect physiology, and in particular metabolism, to questions in ecology. The investigation of the linkage between the environment and the evolution of metabolism is tractable because these experiments manipulate a very simple environment to produce predictable evolutionary outcomes. In doing so, microbial selection experiments can examine the causal elements of natural selection: how specific traits in varying environments will yield different fitnesses. Here, we review the methodology of microbial evolution experiments and address three issues that are relevant to ecologists: genotype-by-environment interactions, ecological diversification due to specialization, and negative frequency-dependent selection. …
