Book Description
The purpose of this study was to investigate the benthic macroinvertebrate communities of Looney Creek, a headwater tributary of the Poor Fork of the Cumberland River which originates on Black Mountain in Harlan County, Kentucky. Background research indicates that impacts to Looney Creek have included mining, logging, and improper management of wastewater, flow alteration and to some degree, urban runoff. These impacts have been documented since around 1917. The objectives of this project were to (a) determine the overall biological integrity of Looney Creek, (b) assess the effects of water conditions on benthic macroinvertebrates that are sensitive to nonpoint source pollution (NPS), (c) identify the sites most impacted by NPS pollution, (d) compare the biological metrics of the monitoring stations over one year, and (e) to compare the biological metrics of the upper two sites and the lower sites to the reference Macroinvertebrate Biotic Index (MBI) as defined by Kentucky Division of Water, Standard Operating Procedures (KDOW 2008). Biological investigations included two upstream and two downstream macroinvertebrate sites which were sampled three times (spring, summer, and fall of 2008), and followed the semi-quantitative and qualitative sampling methodology decribed in the (KDOW 2008). A habitat assessment and a MBI were determined for each study site. Scores indicated seasonal differences in MBI metrics which could be influenced by life history strategies of individual species. The overall average MBI results upstream sites indicate an excellent-good water quality designation and poor-fair for the downstream sites. Site 1 appeared to be the most impacted by NPS with the lowest biotic metrics. Overall, Looney Creek Site 4 appeared to be the least impacted by human activities. This is demonstrated through the low numbers of pollution tolerant individuals, the lowest mHBI (Modified Hilsenhoff Biotic Index), diverse functional feeding groups, and the highest habitat assessment scores.

Book Description
Biodiversity is among the richest treasures of the earth. Despite their small size, microbes play a vital role in environmental monitoring and making the earth sustainable. Microorganisms preserve and assist plants and animals o either directly or indirectly, and, due to their omnipresence in nature, they inhabit conditions such as extreme temperatures, water, soil, salt, medical wastes, agricultural wastes, and air. Microbes are also important in human culture and play an essential role in existence of life. They are present in food fermentation, sewage treatment, medical, agricultural, and soil waste, antibiotics, soil fertility, model organisms, and human microbiota, aid with decomposition, and are responsible for infectious diseases. This volume represents an important contribution to the field, highlighting the importance of microbial biodiversity to society.
