Effects Of Nitrogen Deposition And Flow Permanence On Stream Organic Matter Dynamics, Michael Andrew Joseph Chadwick
Effects Of Nitrogen Deposition And Flow Permanence On Stream Organic Matter Dynamics, Michael Andrew Joseph Chadwick
Electronic Theses and Dissertations
The objective of this study was to investigate the effects of N enrichment and flow permanence on stream organic matter dynamics at the Bear Brook Watershed in Maine (BBWM). BBWM is a paired-catchment manipulation of atmospheric (NH4)2SO4 deposition, and the goal of the experiment is to understand how increased N affects forested catchments. The treatment has increased stream nitrate and foliar N concentrations in the treatment watershed. Because streams draining BBWM are intermittent, this investigation provided an opportunity to investigate the combined effects of stream flow permanence and human alteration of N cycling in a …
Assemblages Of Salamanders (Family Plethodontidae) In Cwa 305(B) Fully-Supporting, Partially-Supporting, And Non-Supporting Streams On Walden's Ridge, Tennessee, Jason M. Houck
Masters Theses and Doctoral Dissertations
Surface mining throughout the southeastern United States leading to acid mine drainage (AMD) has caused significant declines in plethodontid salamander communities in AMD affected streams. The Clean Water Act (CWA) requires that each navigable body of water in the United States be assigned a use designation and a support status based upon the stream's use designation and how it is affected by local pollution to be published in the CW A 305(b) report. Three streams on the Cumberland Escarpment, outside of Chattanooga, Tennessee, representing CWA 305(b) fully-supporting, partiallysupporting, and non-supporting status were surveyed for aquatic plethodontid salamanders. Plethodontid salamanders were …
One Hundred Years Of Environmental Pollution At Chattanooga Creek: A Review Of Selected Studies, Connie C. Kennedy
One Hundred Years Of Environmental Pollution At Chattanooga Creek: A Review Of Selected Studies, Connie C. Kennedy
Masters Theses and Doctoral Dissertations
When studying local Chattanooga history, one cannot ignore the issues of pollution in the city and the environmental degradation of the Chattanooga Creek. Throughout the past one hundred years, the Chattanooga Creek was subjected to multiple inputs of pollutants, beginning with animal wastes in the early 1900s, coal tar from government operated coke ovens during the WWII era, and large amounts of industrial wastes in the latter part of the century. Today the creek is officially closed to the public but the status of its water and sediments remains dangerously polluted. Several research projects throughout the past two decades have …
