Nutrients, Aquatic Food Webs, and Fisheries Management - Part 1

Monday, September 9, 2013: 1:00 PM-5:00 PM
Manning (The Marriott Little Rock)
Nutrients such as nitrogen and phosphorus are fundamental to life and can limit biological processes at the scales of individuals, populations, communities and ecosystems. A significant challenge in fisheries science is quantifying the direct and indirect connections between nutrient concentrations in waterbodies and community structure and production of multiple trophic levels in response to bottom up and top down resource management. This symposium will bring together a diverse group of scientists interested in linkages between nutrient biogeochemistry and population, community, and ecosystem ecology. We seek presentations aimed at quantifying the flow of nutrients through the aquatic food web and the chemical, energetic, or stoichiometric constraints on these processes. Presentations may focus on any aspect of nutrient-aquatic food web interactions such as physiological ecology; population or community ecology of primary producers, heteterotrophic microbes, zooplankton, macroinvertebrates, or fish; trophic interactions; or ecosystem management. The interdisciplinary nature of this symposium should attract fish ecologists and fisheries managers, as well and stream ecologists and limnologists. A compilation of diverse scientists is valuable for moving each of the individual disciplines forward by addressing issues and research areas of common concern.
