Amy D. Rosemond is an American

ecosystem function. She was elected an Ecological Society of America fellow in 2018,[3] and served as president of the Society for Freshwater Science from 2019-2020.[4]

Education and early career

Rosemond grew up in

University of North Carolina, Chapel Hill. She remained at the University of North Carolina, Chapel Hill to complete her Master of Arts degree in biology
.

Rosemond went on to earn a Ph.D. in biology at Vanderbilt University, where she was co-advised by Vanderbilt faculty Susan Brawley and Oak Ridge National Laboratory research scientist Patrick J. Mulholland. Rosemond conducted her dissertation research at the Oak Ridge National Lab, in Tennessee, USA, studying how both top-down predation and bottom-up nutrient availability affect periphyton in headwater streams.

After completing her Ph.D. in 1993, Rosemond was awarded a National Science Foundation postdoctoral research fellowship in environmental biology. She completed her postdoc at the Institute of Ecology at the University of Georgia, during which she conducted research at La Selva Biological Station in Costa Rica examining the top-down and bottom-up effects of predatory fishes and shrimps and phosphorus, respectively, on leaf-litter breakdown and carbon processing.[6][7] While working at La Selva, Rosemond also conducted research on landscape-scale variation in stream phosphorus concentrations, and its effects on stream detritivore food webs.[8]

Career

Rosemond worked as the assistant director of the

Excess nutrients and stream ecosystem function

Leveraging partnerships with the Coweeta Hydrologic Lab

benthic macroinvertebrates, and higher trophic levels, including salamanders, respond to nitrogen and phosphorus pollution. Her research in this area focuses on how terrestrially-derived detrital carbon, including leaves, sticks, and wood that fall into streams, is processed and transmitted through aquatic food webs that are exposed to excess nutrients. She has led research to test the relative importance of nitrogen and phosphorus limitation in stream carbon processing through whole-stream nutrient enrichment studies. Through this work, Rosemond and her collaborators have increased understanding of how nutrients affect energy flow in detritus-based food webs, as previous research on nutrient effects in streams often focused on photosynthetic, algal pathways.[10][11]
