Book Synopsis Stressor-response Relationships Between Landscape Features and Benthic Macroinvertebrate Indices Using the USEPA Wadeable Stream Assessment Program Data by : Katherine Page Shurgar
Download or read book Stressor-response Relationships Between Landscape Features and Benthic Macroinvertebrate Indices Using the USEPA Wadeable Stream Assessment Program Data written by Katherine Page Shurgar and published by . This book was released on 2007 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2004 the USEPA conducted the National Wadeable Stream Assessment (WSA) in order to measure and report the state of rivers and streams in the U.S. (USEPA, 2004). A total of 500 sites were surveyed for the nationwide study. Results from the study were aggregated into nine reporting ecoregions in order to provide statistical robustness in comparing sample sites with reference conditions. In the Interior Highlands of Arkansas, Missouri, and Oklahoma, 32 sites were sampled for the WSA project. The purpose of our study was to investigate the utility of this limited data set in determining stressor-response relations in an ecoregion smaller than one of the nine regions designed by the USEPA. A hierarchical approach using multivariate, step-wise, and correlation analyses was developed in order to examine the scalar relations of catchment and reach scale influences on stream conditions, and to evaluate macroinvertebrate assemblages for detection of impact. The strongest model relations (P=0.0001) were the combined effect of land cover, riparian conditions, and geomorphology on percent Wood (R2=0.76), Mean Substrate Diameter (R 2=0.72) and percent Coarse Gravel (R2=0.71). Model predictions of land cover impacts were found to significantly (P

This book was released on 2014 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmers have been encouraged to adopt more sustainable farming practices (BMPs) that mitigate adverse agricultural effects on the natural environment. However, the ability of BMPs to protect or restore riverine systems continues to be questioned due to limited evidence directly linking BMP use with improved ecological conditions. The exclusion of hydrological pathways in previous field studies may explain why a direct link has not yet been established. The goal of this study was to assess the association between benthic macroinvertebrate community structure and the number and location of agricultural BMPs. Macroinvertebrates and water chemistry were sampled in 30 headwater catchments in the Grand River Watershed. Catchments exhibited gradients of BMP use and location as measured by the degree of hydrologic connectedness. Stepwise ordination regressions and variance partitioning were used to determine which environmental variables (i.e., BMP metrics, water chemistry parameters, habitat characteristics, and land use variables) were associated with benthic macroinvertebrate community structure. Water chemistry parameters were negatively associated with BMP metrics suggesting BMPs were mitigating losses of nutrients and sediments. However, BMP abundance and location explained minimal variation in benthic macroinvertebrate structure within the 30 sampled catchments. The absence of a strong association between BMPs and benthic macroinvertebrates may indicate a need for greater numbers and targeted siting of BMPS to improve water quality beyond a threshold point that would allow recolonization of intolerant invertebrate taxa. Focusing of conservation goals on ecological conditions and the promotion of BMPs that enhance in-stream habitat may also be required.
Book Synopsis Concordance Among Fish and Macroinvertebrates, Environmental Filters, and Restoration in Small Tributaries by : Amelia T. McReynolds

This book was released on 2020 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small tributaries to the Great Lakes are threatened by intensifying land use, barriers to fish movement, and the resulting degradation of water quality and aquatic communities. Recently, restoration efforts have turned to these small but numerous streams as a target which may respond relatively quickly and positively to actions across the watershed. In lower Green Bay, Lake Michigan, small tributaries are scattered across a patchwork of agriculture, developed land, and forest, and have been impacted by landscape-scale stressors. Large-scale collaborative restoration efforts have identified them as a potentially valuable habitat for macroinvertebrates and fish which could play a role in the restoration of the lower Fox River-Green Bay as a system. However, it is unclear how fish and macroinvertebrate communities vary throughout this set of tributaries, and how they are shaped by dynamic environmental conditions. Given this uncertainty, it is difficult to prescribe restoration actions effectively. The first chapter of this thesis will identify environmental variables at several spatial scales that shape fish and macroinvertebrate communities and describe the concordance between these two communities at eighteen stream reaches. Two years of monitoring efforts inform this analysis while revealing strong spatial and temporal variation in stream conditions. Fish and macroinvertebrate communities respond to many of the same environmental variables at multiple spatial scales, exhibiting community concordance which is influenced by connectivity and tributary-specific environmental conditions. In the second chapter, results of this study and prior research in small tributaries to Green Bay will be used with a synthesis of the literature to make restoration recommendations. Many of the same central principles used to guide restoration in dendritic streams may be adapted and applied to small tributaries, given sufficient knowledge of each unique tributary system.

Book excerpt: Urban Geomorphology: Landforms and Processes in Cities addresses the human impacts on landscapes through occupation (urbanization) and development as a contribution to anthropogenic geomorphology or "anthropogeomorphology." This includes a focus on land clearance, conservation issues, pollution, decay and erosion, urban climate, and anthropogenic climate change. These topics, as well as others, are considered to shed more light on the human transformation of natural landscapes and the environmental impacts and geomorphological hazards that environmental change can encompass. Its multidisciplinary approach is appropriate for audiences from a range of disciplines and professions, from geologists, conservationists, and land-use planners to architects and developers. Urban Geomorphology not only transcends disciplines, but also covers varied spatial-temporal frameworks and presents a diverse set of approaches and solutions to human impacts and geomorphological hazards within urban landscapes. Features a cross-disciplinary perspective, highlighting the importance of the geosciences to environmental science, engineering, and public policy Focuses on the built environment as the location of concentrated human impacts and change Provides an international scope, including case studies from urban areas around the world

Download or read book Water Quality: Monitoring and Assessment written by Stephanie Fraser and published by . This book was released on 2020-09-08 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological, radiological, chemical and physical traits of water are known as water quality. It is a measure of the water condition related to the requirements of biotic species and to human need. The health of ecosystems, safety of human contact, and drinking water are the most common standards used to measure water quality. Water quality parameters can be categorized into human consumption, environmental water quality, and industrial and domestic use. The measurement of water quality includes the process of sample collection, chemical analysis, real-time monitoring and testing in response to natural disasters. Various environmental indicators such as physical, chemical and biological indicators are also observed and used for the monitoring of water quality. This book explores all the important aspects of water quality in the present day scenario. It elucidates new techniques and their applications in a multidisciplinary manner. It will prove to be immensely beneficial to students and researchers in this field.
