Macroinvertebrate and crayfish communities in the Meramec River drainage basin: an investigation at multiple spatial scales
(University of Missouri--Columbia, 2006)
Hierarchical classification systems have been widely used to delineate terrestrial ecounits at multiple spatial scales; however there has long been a need for an aquatic based classification system. A newly developed aquatic ...
River restoration in the upper Mississippi River Basin
(University of Missouri--Columbia, 2006)
River restoration has become an important management choice to address causes and effects of surface water impairment and river modification in the Upper Mississippi River Basin (UMRB). I report information on individual ...
Hydrology, vegetation and waterbird response to land management strategies in the San Luis Valley
(University of Missouri--Columbia, 2006)
available to wetland dependent species. I examined the hydrologic regime, vegetation community composition and structure and waterbird use of seasonal wet meadow and temporary playa wetlands located on public and private land subject to idle, grazing...
Disinfection by-product precursors and formation potentials of Missouri reservoirs
(University of Missouri--Columbia, 2006)
Dissolved organic carbon (DOC) in surface water affects the formation of halogenated disinfection by-products (DBP) in drinking water. Both the quality and quantity of DOC impact DBP formation. Allochthonous DOC is more ...
Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
(University of Missouri--Columbia, 2006)
During stressful periods, glucocorticoid production is increased. Glucocorticoid metabolites are found in blood, urine and feces. Our first goal was to determine if fecal glucocorticoid metabolite (FGM) measurements are a ...
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)
Channel modification and flow regulation in historically braided large rivers, have reduced sandbars and associated highly productive habitats for riverine biota. Sandbars are an important interface between aquatic and ...
Use of main channel and shallow-water habitat by larval fishes in the lower Missouri River
(University of Missouri--Columbia, 2006)
I developed a series of research objectives organized in a spatial hierarchy to characterize larval fish nursery habitat within the lower Missouri River. Native carpsucker spp./buffalo spp. (Carpiodes spp./Ictiobus spp.) ...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
Sediment is suspected in the decline of sensitive-aquatic organisms in the Osage River basin of Missouri. In this study, I monitored sediment dynamics and evaluated corresponding linkages with benthic invertebrate and fish ...
Great Lakes lake trout early mortality syndrome (EMS) : contaminants, thiamin status, and their possible interaction
(University of Missouri--Columbia, 2006)
Salmonid populations in the Great Lakes experienced a decline in the early twentieth century, presumably due to over-fishing combined with the introduction of exotic parasites such as the sea lamprey. Despite intensive ...
