Effects of Low Flow on Sierra Nevada Stream Food Webs
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.
