Book Description
Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Book Description
Straddling temperate forests and grassland biomes and stretching along the coastline of two Great Lakes, Wisconsin contains tallgrass prairie and oak savanna, broadleaf and coniferous forests, wetlands, natural lakes, and rivers. But, like the rest of the world, the Badger State has been transformed by urbanization and sprawl, population growth, and land-use change. For decades, industry and environment have attempted to coexist in Wisconsin—and the dynamic tensions between economic progress and environmental protection makes the state a fascinating microcosm for studying global environmental change. The Vanishing Present brings together a distinguished set of contributors—including scientists, naturalists, and policy experts—to examine how human pressures on Wisconsin’s changing lands, waters, and wildlife have redefined the state’s ecology. Though they focus on just one state, the authors draw conclusions about changes in temperate habitats that can be applied elsewhere, and offer useful insights into future of the ecology, conservation, and sustainability of Wisconsin and beyond. A fitting tribute to the home state of Aldo Leopold and John Muir, The Vanishing Present is an accessible and timely case study of a significant ecosystem and its response to environmental change.

Book Description
The main problem in North America is the location of water resources relative to large population centers where the majority of the freshwater drains away from the bulk of the population. Climate variability and change is a reality. It raises the impact on variability and availability within the continent, which is characterized by its different climatic regions. The hydo-vulnerability of North America is tempered and governed by agreements, laws and institutions such as International Joint Commission (IJC) and International Boundary & Water Commission (IBWC), which have been created to resolve transboundary water issues in a cooperative manner for over a century, resulting in minimal conflicts in the region.
