Concentrations of zinc and lead are elevated in streams draining historic mining areas of the Ozarks. These metals are potentially damaging to many freshwater organisms, including endangered species of native freshwater mussels. The goal of this collaborative project between the USFWS, USGS, and MSU is to generate zinc and lead toxicity data in water or sediment using both laboratory and field assessments.
Aquatic Biology Projects
U.S. EPA is sponsoring research on the effects of low oxygen on native freshwater mussels, many of which are in danger of extinction. This information will aid regulatory agencies in establishing standards for dissolved oxygen in rivers and lakes.
This study examined the spatial distribution and abundance of plankton in the James River arm of Table Rock Lake, Missouri USA, a water body under special scrutiny because of deteriorating water quality linked to increased urbanization and livestock operations in the watershed.
Despite several decades of research on eutrophication in lakes, changes in reservoir plankton communities are poorly understood. The current study examined spatial patterns and dynamics of algae and zooplankton in an oligo-mesotrophic main-stem reservoir, Bull Shoals Lake, Missouri-Arkansas, which is currently threatened from rapid development in upstream reservoirs.
URS Corporation is contracting the Ozarks Environmental and Water Resources Institute (OEWRI) at Missouri State University to complete the identification, counting, indexing, and reporting for 60 macroinvertebrate samples collected from Missouri streams.
