Angelo Coast Range Reserve

The projected effects of climate change most relevant to river food webs include increases/decreases in water temperature, increases/decreases in water velocity and increases/decreases in solar radiation delivered to the river channel. My experiment will examine the combined and separate effects of these factors on the growth and interaction of two focal primary producers in the Eel River food web: Cladophora glomerata (the dominant benthic algae) and Epithemia spp. (the dominant epiphytic diatom). Net growth, nutrient uptake, metabolism, nitrogen fixation and colonization of this pair of organisms will be measured using in-stream channels and cooled or warmed water from the South Fork Eel River and Elder Creek, with gates providing two velocity regimes (slow and fast) and shade cloth providing two light treatments (fog immersion and full sunlight). Understanding the relationship between these two significant primary producers under different climatic conditions will substantially further our understanding of the ecological significance of this interaction and of these two organisms to the river foodweb.
