Available in PDF, EPUB and Kindle. Book excerpt: Think of the Highlands as the “backyard” and “backstop” of the Philadelphia–New York–Hartford metroplex. A backyard that spans over three million acres across Pennsylvania, New York, and Connecticut, the Highlands serves as recreational open space for the metroplex’s burgeoning human population. As backstop, Highlands’ watersheds provide a ready source of high-quality drinking water for over fifteen million people. The Highlands is the first book to examine the natural and cultural landscape of this four-state region, showing how it’s distinctive and why its conservation is vital. Each chapter is written by a different leading researcher and specialist in that field, and introduces readers to another aspect of the Highlands: its geological foundations, its aquifers and watersheds, its forest ecology, its past iron industry. In the 1800s, the Highlands were mined, cutover, and then largely abandoned. Given time, the forests regenerated, the land healed, and the waters cleared. Increasingly, however, the Highlands are under assault again—polluted runoff contaminating lakes and streams, invasive species choking out the local flora and fauna, exurban sprawl blighting the rural landscape, and climate change threatening the integrity of its ecosystems. The Highlands makes a compelling case for land use planning and resource management strategies that could help ensure a sustainable future for the region, strategies that could in turn be applied to other landscapes threatened by urbanization across the country. The Highlands are a valuable resource. And now, so is The Highlands.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied. Having worked extensively in academia and industry, the Editor-in-Chief has been careful about constructing a work for a shared audience and cause

This book was released on 2022-08-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern ecological and environmental sciences are dominated by observational data. As a result, traditional statistical training often leaves scientists ill-prepared for the data analysis tasks they encounter in their work. Bayesian methods provide a more robust and flexible tool for data analysis, as they enable information from different sources to be brought into the modelling process. Bayesian Applications in Evnironmental and Ecological Studies with R and Stan provides a Bayesian framework for model formulation, parameter estimation, and model evaluation in the context of analyzing environmental and ecological data. Features: An accessible overview of Bayesian methods in environmental and ecological studies Emphasizes the hypothetical deductive process, particularly model formulation Necessary background material on Bayesian inference and Monte Carlo simulation Detailed case studies, covering water quality monitoring and assessment, ecosystem response to urbanization, fisheries ecology, and more Advanced chapter on Bayesian applications, including Bayesian networks and a change point model Complete code for all examples, along with the data used in the book, are available via GitHub The book is primarily aimed at graduate students and researchers in the environmental and ecological sciences, as well as environmental management professionals. This is a group of people representing diverse subject matter fields, who could benefit from the potential power and flexibility of Bayesian methods.

Available in PDF, EPUB and Kindle. Book excerpt: As the world's population continues to grow, the continual development of riparia areas stresses stream ecosystems. These collected articles aim to provide researchers, aquatic resource managers, land use planners and others with the results of recent studies of the effects of urbanization on stream ecosystems. By presenting fifteen case studies and five regional comparisons, the editors of these proceedings hope to help protect streams form the damages of what they recognize as inevitable urbanization. Foci of the studies include the effects of urbanization on biological diversity and populations, geology, hydrology, and economics.

Download or read book Associations Between Hydrogeomorphic Characteristics and Biotic Community Dynamics in Urban Streams of Columbus Ohio USA written by Leslie O. Rieck and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization of watersheds leads to myriad changes to streams, including modified sediment and streamflow regimes that can result in altered fluvial geomorphic processes and channel structure. Hydrogeomorphic features have been linked to community composition of aquatic biota, as well as to stream ecosystem functioning. Biotic communities in urban stream ecosystems can be markedly different than their counterparts in more natural streams, often exhibiting reduced abundance, diversity, and shifts in assemblage composition, though the specific mechanisms through which urban land use and subsequent hydrogeomorphic modification effects these changes remain unresolved. Hydrogeomorphic modifications may impact both instream habitat as well as connectivity to the surrounding landscape, influencing both biotic assemblage composition as well as ecological connectivity between streams and their adjacent riparian zones. In 23 small urban stream reaches in the Columbus Metropolitan Area (CMA), Ohio, USA, I investigated potential linkages between urban-induced hydrogeomorphic characteristics and: (1) fish assemblage compositional changes over time (3-5 years); (2) fish assemblage trophic dynamics; (3) aquatic-to-terrestrial nutritional subsidies to a common riparian consumer (spiders of the family Tetragnathidae); and (4) downstream drift of larval macroinvertebrates in the water column. Hydrogeomorphic features related to instream habitat, the hydraulic environment (e.g., slope, shear stress, D50 [median bed sediment particle size]) and stream-floodplain connectivity (e.g., entrenchment ratio, sinuosity, incision ratio) emerged as common influences on fish assemblage composition and trophic dynamics, aquatic-terrestrial connectivity, and invertebrate drift. At a subset of 12 study reaches, several hydrogeomorphic variables showed significant changes over 3-5 years, with many decreasing (e.g., discharge [by 39%], slope [by 0.1%], and shear stress [by 29%, which decreased in concert with slope]). Fish assemblage evenness decreased over the study period in study reaches with higher incision ratio (t = 2.16, p = 0.039), accompanied by species-specific relationships with hydrogeomorphic characteristics. These findings explicitly link hydrogeomorphic and fish-community changes over time, showing that fluvial geomorphic forms in urban streams are not static, and can exert effects on fish assemblages over relatively short time periods, likely via shifts in instream habitat. In a wider suite of 23 study reaches, hydrogeomorphic characteristics – including slope and bankfull discharge – influenced fish-assemblage diversity (H’), density, and proportion of generalist foragers. Mean reliance on aquatically-derived energy (i.e., reliance on energy pathways derived from benthic algae) of Creek Chub (Semolitus atromaculatus) was 0.60, which increased with slope (Z = 2.27, p = 0.023), suggesting that channel gradient, a measure highly associated with shear stress, may moderate the relative abundance of autochthonous vs. allochthonous basal resources consumed by stream fish. Sunfish species (Lepomis cyanellus and L. macrochirus) relied on aquatically-derived energy for 0.62 of their nutrition, which was positively related to discharge (Z = 1.98, p = 0.048), suggesting an underlying mechanism of discharge-mediated bed disturbance as a control of basal resource availability. Hydrogeomorphic variables did not influence mean trophic position or food-chain length (FCL; ranging from 1.83-4.69 across all study reaches), which was more closely related to water nutrient concentrations (i.e., total N). Tetragnathid spider trophic position (x ̅ = 2.41) was negatively influenced by D50, while tetragnathid reliance on aquatically-derived energy (x ̅ = 0.43) trended positively with sinuosity (t = 2.10, p = 0.054), suggesting that tetragnathid spider trophic position is influenced by the impact of instream habitat on emergent aquatic insects, while aquatically-derived energy was more closely related to stream-floodplain connectivity. Tetragnathid density decreased with slope (t = -2.51, p = 0.023), as did the flux of emergent aquatic insects into the riparian zone (t = -2.27, p = 0.037). The relative abundance of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa in emergent aquatic insect assemblages was positively associated with sinuosity (t = 6.84, p
