Available in PDF, EPUB and Kindle. Book excerpt: Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.

Available in PDF, EPUB and Kindle. Book excerpt: The brook trout (Salvelinus fontinalis) is an iconic species among fly anglers and cold-water conservationists in eastern North America. This fish registers as a powerful symbol for its beauty and its imagery in art and literature. Its presence also tells us a great deal about the health of the larger environment. When an angler has a brook trout in hand, there is confidence that the water is close to pristine. Besides being an important indicator species, the brook trout, with its gold and reddish markings and its camouflaged green and black back, is one of the most beautiful freshwater fish in North America. And beyond the beauty of the fish itself, the environment in which it is found is also part of its past and present appeal. To fish for brook trout is often to fish in the last remote and rugged landscapes in the East, “fishscapes” that have not been polluted by stocking trucks that dump nonnative brown and rainbow trout in most of the East’s accessible cold waterways. Searching for Home Waters is part science, part environmental history, and part personal journey of the author, Michael K. Steinberg, and those he interviewed during his travels. The work takes a broad perspective that examines the status of brook trout in the eastern United States, employing a “landscape” approach. In other words, brook trout do not exist in a vacuum; they are impacted by logging, agriculture, fishing policies, suburban development, mining, air pollution, and climate change. Thus, while the book focuses specifically on the status and management of the brook trout—from Georgia to Labrador—it also tells the larger story of the status of the eastern environment. As a “pilgrimage,” this book is also a journey of the heart and contains Steinberg’s personal reflections on his relationship with the brook trout and its geography.

This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant changes have occurred in the distribution of trout in streams of Great Smoky Mountains National Park since 1900. By the mid-1970's the original range of the native brook trout had been reduced by about 70% and the species was relegated to suboptimal habitat in head water streams. Most of the stream sections lost by brook trout became the territory of the introduced rainbow trout, which in 1977 occupied about 80% of the Park waters. After 1950, brown trout introduced in State waters outside the Park established reproducing populations in some 50 miles of stream formerly occupied only by rainbow trout. If current trends continue, the recovery of brook trout in Park water may be difficult, if not impossible, and brown trout may occupy much of the territory now held by rainbow trout.

This book was released on 2010 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research supports development of aquatic resource management strategies to address acid deposition in the Great Smoky Mountain National Park (GRSM) by 1) developing relationships between baseflow and stormflow chemical constituents and examining effects of elevation, area, geology, soil, and vegetation on stream chemistry; 2) evaluating physiological condition in brook trout in relation to changes in stream chemistry during stream acidification episodes, and 3) evaluating brook trout metrics with respect to stream chemistry, basin characteristics, and ecologically relevant hydrologic parameters. (1) Stream chemistry was monitored in eight GRSM streams considering basin area, site elevation, Anakeesta geology, soil, and vegetation. Following precipitation events, pH was significantly reduced and aluminum concentrations increased, while the concentration response of ANC, nitrate, sulfate, and base cations varied. Higher pH and ANC concentrations were observed in large and low-elevation streams. (2) Caged brook trout were exposed to two acid episodes during in situ bioassays conducted in three GRSM streams. Stream pH decreased (>0.7 pH units) and total dissolved aluminum increased (>0.175 mg/L) at all three sites during acid episodes. Whole-body sodium concentrations were significantly reduced (10-20%) when preceding 24-h time weighted average pH values (4.88, 5.09, 4.87) and corresponding 24-h aluminum concentrations (210, 202, 202 [mu]g/L). Lower whole-body sodium concentrations were correlated with elevated proton and aluminum concentrations indicating physiological distress. (3) Water chemistry, hydrology and physical basin factors influenced brook trout distributions and densities in 16 collocated fish and water quality sampling sites (1990-2009). Higher concentrations of ANC, pH, sodium, and soil cation exchange capacity, and higher fall flows were associated with the presence of brook trout. Trout densities were higher in streams with higher concentrations of sodium, suggesting that sodium may ameliorate the effects of acid toxicity. These relationships provide useful information where GRSM managers can prioritize conservation and restoration efforts.

This book was released on 2019 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenically driven factors, such as increasing temperature and sediment in valley streams, acidification of mountain streams, and the introduction of non-native trout, are restricting habitat suitable for healthy populations of eastern brook trout (Salvelinus fontinalis) throughout their native Appalachian range. Brook trout are important as predators of insects in mountain streams and as a favorite of anglers. It is crucial that remaining populations in sustainable habitats be identified and preserved. Waterfalls are geologic knickpoints preventing base-level lowering that create unique, stable landscapes above them, which may alleviate the temperature-productivity/acidity "habitat squeeze" for populations of brook trout and could serve as potentially ideal targets for conservation efforts despite being isolated. This study investigates brook trout occurrence above waterfalls in Virginia and compares brook trout populations found above waterfalls to those below them. One-hundred meter reaches above and below seven waterfalls in Virginia's George Washington and Jefferson National Forest were sampled for brook trout via 3-pass, block-netted, backpack electrofishing depletions. All brook trout were counted, weighed, and measured for fork length. The response variables are differences in 1) percent dominance, 2) population size, 3) biomass, and 4) length-weight index (Fulton's Condition Factor) between brook trout above and below waterfalls. Brook trout dominance (100 vs. 36.9%) is greater above than below waterfalls, but not significantly (p = 0.1003). We found abundance (26 vs.12 individuals per 100m) and overall biomass (885.3 vs 284.6 grams per 100m) of brook trout populations above waterfalls to be significantly greater than their below waterfall counterparts (p = 0.078 for both). We also found brook trout above waterfalls to have a higher condition factor (1.086g/cm3 vs 1.0636g/cm3) than those below waterfalls (p = 0.031). Lastly, we found populations above waterfalls where their occurrence was previously unknown. Despite being isolated, brook trout populations above waterfalls were just as if not more robust than those below and may be excellent targets for conservation.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater Ecology and Evolution, Second Edition is designed to meet a multitude of audience needs. The state of the art in the discipline is provided by the articulation of six sections. The first three sections successively carry the reader into the basic attributes of groundwater ecosystems (section 1), the drivers and patterns of biodiversity (section 2), and the roles of organisms in groundwater ecosystems (section 3). The next two sections are devoted to evolutionary processes driving the acquisition of subterranean biological traits (section 4) and the way these traits are differently expressed among groundwater organisms (section 5). Finally, section 6 shows how knowledge acquired among multiple research fields (sections 1 to 5) is used to manage groundwater biodiversity and ecosystem services in the face of future groundwater resource use scenarios. Emphasis on the coherence and prospects of the whole book is given in the introduction and conclusion. - Provides a modern synthesis of research dedicated to the study of groundwater biodiversity and ecosystems - Bridges the gap between community ecology, evolution, and functional ecology, three research fields that have long been presented isolated from each other - Explains how this trans-disciplinary integration of research contributes to understanding and managing of groundwater ecosystem functions - Reveals the contribution of groundwater ecology and evolution in solving scientific questions well beyond the frontiers of groundwater systems

Available in PDF, EPUB and Kindle. Book excerpt: With regional, national, and global processes affecting both the structure and function of lakes and rivers, assessment methodology must encompass many attributes to evaluate the impact of these processes on water quality. Many of the changes in biological communities correlate to resource exploitation, nonpoint pollutant interactions, and habitat alteration - factors that can be missed by routine chemical sampling. This creates the need for ecologically-based approaches to this problem. Biological monitoring is a fundamental part of an ecologically-based approach. Biological Monitoring of Aquatic Systems brings together contributions by authors recognized as leaders in the development and utilization of biological monitoring techniques for freshwater ecosystems. It provides a conceptual framework for the use of biological monitoring to assess the environmental health of freshwater resources. Biological monitoring is an important part of any water quality assessment program. Biological Monitoring of Aquatic Systems provides you with an understanding of water resources. It includes discussions concerning historical development, ecological basis, experimental design characteristics, case studies, and future concerns. As efforts to maintain and restore the world's water resources intensify, the need to develop accurate methods to assess the health of these resources becomes critical.

Available in PDF, EPUB and Kindle. Book excerpt: Japan’s traditional and fragile satoyama landscape system was developed over centuries of human life on mountainous island terrain in a monsoon climate. The carefully managed coppice woodlands on the hillsides, the villages strung along the base of the hills, and the carefully tended paddy fields of rural Japan made possible the sustainable interaction of nature and humans. Radical changes in the middle of the twentieth century led to the abandonment of satoyama landscapes which now are being rediscovered. There is a new realization that these woodlands still play a vital role in the management of the Japanese landscape and a new determination to manage them for the future. This multifaceted book explores the history, nature, biodiversity, current conservation measures, and future uses of satoyama. The information presented here will be of interest in all parts of the world where patterns of sustainable development are being sought.

This book was released on 1998 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream habitat is characterized in the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program as part of an integrated physical, chemical, and biological assessment of the Nation's water quality. The goal of stream habitat characterization is to relate habitat to other physical, chemical, and biological factors that describe water-quality conditions. To accomplish this goal, environmental settings are described at sites selected for water-quality assessment. In addition, spatial and temporal patterns in habitat are examined at local, regional, and national scales. This habitat protocol contains updated methods for evaluating habitat in NAWQA Study Units. Revisions are based on lessons learned after 6 years of applying the original NAWQA habitat protocol to NAWQA Study Unit ecological surveys. Similar to the original protocol, these revised methods for evaluating stream habitat are based on a spatially hierarchical framework that incorporates habitat data at basin, segment, reach, and microhabitat scales. This framework provides a basis for national consistency in collection techniques while allowing flexibility in habitat assessment within individual Study Units. Procedures are described for collecting habitat data at basin and segment scales; these procedures include use of geographic information system data bases, topographic maps, and aerial photographs. Data collected at the reach scale include channel, bank, and riparian characteristics.
