Book Description
Non-point source pollution (NPS), especially from agricultural runoff, is a leading contributor to water quality impairments in the U.S. Lately, attention to nutrient pollution, specially to phosphorus, has arisen due to disturbing increases in seasonal toxic blue-green algal blooms. To improve our understanding of how land use and seasonal weather patterns impact runoff and nutrient loading in temperate areas, we investigated the effect of different land uses on P inputs into Owasco Lake, in central NY. In addition, the inputs were evaluated in the context of a prolonged drought that affected the northeastern U.S. during 2016. Monitoring of base and high flow conditions was conducted between December 2015 and November 2016 at sites located along twelve tributaries to the lake, representing the dominating land uses in the watershed (i.e.: agriculture and forest). Small watersheds were chosen to be able to isolate impacts of particular land uses. The results show a strong interaction of seasonal and land use effects, with the drought event masking the effect of agricultural and mixed land use on P loads; and with the highest loads registering during the first rain event after the drought, exacerbating the agricultural impact on water quality. These findings are an important contribution from a management perspective, as projections for the Northeast US suggest that, although total precipitation will remain relatively stable, summer rains are likely to become concentrated in fewer events of higher intensities, interspaced with more prolonged dry periods. We consider it absolutely critical to incorporate detailed timing management practices for fertilizer and/or manure application relative to runoff producing storm events, in order to mitigate climate extremes impact on water quality.

Book Description
This book honors the career of Professor Elizabeth Gierlowski-Kordesch who was a pioneer and leader in the field of limnogeology since the 1980s. Her work was instrumental in guiding students and professionals in the field until her untimely death in 2016. This collection of chapters was written by her colleagues and students and recognize the important role that Professor Gierlowski-Kordesch had in advancing the field of limnogeology. The chapters show the breadth of her reach as these have been contributed from virtually every continent. This book will be a primary reference for scientists, professionals and graduate students who are interested in the latest advances in limnogeologic processes and basin descriptions in North and South America, Europe, Africa, and China. *Free supplementary material available online for chapters 3,11,12 and 13.

Book Description
Lakes of New York State, Volume I: Ecology of the Finger Lakes describes the state of Finger Lakes, which is a group of eleven elongated bodies of water of glacial origin in the west-central portion of New York, and its respective watershed. This book assesses the structure of the Finger Lakes' plant and animal communities and how these communities interact with the abiotic components of the environment. The condition of the lakes from the standpoint of fish population dynamics are also analyzed, including an examination of the various physical, chemical, and biological aspects of the lakes' ecosystem. This text ranks the Finger Lakes into a unilateral trophic list by tabulating their trophic information according to three commonly used indicator measurements— average summer Secchi disc depth, average summer chlorophyll a concentration, and average winter total phosphorus level. This publication is valuable to limnologists and ecologists working on temperate zone freshwater lakes.

Book Description
This is a print on demand edition of a hard to find publication. Report of a survey conducted by the EPA and its state and tribal partners of the nation's lakes, ponds and reservoirs. This National Lakes Assessment is designed to provide statistically valid regional and national estimates of the condition of lakes. It uses a probability-based sampling design to represent the condition of all lakes in similar regions sharing similar ecological characteristics. Consistent sampling and analytical procedures ensure that the results can be compared across the country. The National Lakes Assessment helps build state and tribal capacity for monitoring and assessment and promotes collaboration across jurisdictional boundaries in the assessment of water quality. Charts and tables.

Book Description
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Book Description
"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.

Book Description
Here is a refreshing look at how American cities are leading the way toward greener, cleaner, and more sustainable forms of economic development. In Emerald Cities, Joan Fitzgerald shows how in the absence of a comprehensive national policy, cities like Chicago, New York, Portland, San Francisco, and Seattle have taken the lead in addressing the interrelated environmental problems of global warming, pollution, energy dependence, and social justice. Cities are major sources of pollution but because of their population density, reliance on public transportation, and other factors, Fitzgerald argues that they are uniquely suited to promote and benefit from green economic development. For cities facing worsening budget constraints, investing in high-paying green jobs in renewable energy technology, construction, manufacturing, recycling, and other fields will solve two problems at once, sparking economic growth while at the same time dramatically improving quality of life. Fitzgerald also examines how investing in green research and technology may help to revitalize older industrial cities and offers examples of cities that don't make the top-ten green lists such as Toledo and Cleveland, Ohio and Syracuse, New York. And for cities wishing to emulate those already engaged in developing greener economic practices, Fitzgerald shows which strategies will be most effective according to each city's size, economic history, geography, and other unique circumstances. But cities cannot act alone, and Fitzgerald analyzes the role of state and national government policy in helping cities create the next wave of clean technology growth. Lucid, forward-looking, and guided by a level-headed optimism that clearly distinguishes between genuine progress and exaggerated claims, Emerald Cities points the way toward a sustainable future for the American city.

Book Description
Ecosystem research has emerged in recent decades as a vital, successful, and sometimes controversial approach to environmental science. This book emphasizes the idea that much of the progress in ecosystem research has been driven by the emergence of new environmental problems that could not be addressed by existing approaches. By focusing on successes and limitations of ecosystems studies, the book explores avenues for future ecosystem-level research.
