Sierra Nevada snowmelt is predicted to occur up to two months earlier by 2080, but we do not know how aquatic food webs will respond. Changes in snowmelt timing could decrease stream insect abundance and biodiversity via increased temperature and duration of low flows. This project seeks to understand how extended low flows alter stream food webs. My graduate student mentor collected samples from nine artificial streams that had different durations of low flow this past summer. I will help sort and identify these samples, which will ultimately result in an extensive dataset that will include temperature, discharge, light, community composition, primary production, trophic position, insect community growth rates, body size, and emergence timing.
New technologies such as police body cameras and deepfake algorithms have recently put questions of photographys value as evidence in the spotlight. However, photographic technologies have been part of the courtroom since the mid-nineteenth century. This project turns to the emergence of photography and cinema as evidentiary tools in the courtroom in an attempt to uncover the preconditions of our current moment of mediated justice. I will assist my graduate student mentor in advancing the larger project by constructing a newspaper archive for significant early court cases involving moving-image evidence, seeking to answer the question of how film entered American courtrooms. This will involve writing summaries of cases, compiling timelines of events, and identifying significant characters. The work will initially draw from campus collections and online newspaper databases. There will also be the opportunity to undertake further research at other local institutions in the Bay Area and Sacramento.
