Book Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book Description
“The San Francisco Bay Shoreline Guide takes us on a walking and cycling journey around San Francisco Bay, unfolding the wonder, drama and beauty of one of the great estuaries of the world.”--Robert Redford "From the bustling waterfronts of our cities and towns, to our wild, windswept, and thankfully, protected natural wetlands, this is our fantastic guide to all of the magnificence of the San Francisco Bay Shoreline. Grab it and go on world-class journeys in our own backyard. I'll see you along the trail!"--Doug McConnell, Television Producer and Reporter “This guide helps to create an awareness and appreciation of San Francisco Bay.”--Sylvia McLaughlin, co-founder of Save the Bay Praise from the previous edition "There are absorbing stories here for the armchair reader and detailed guides for the active explorer. Read, enjoy, and cultivate your roots in the region."—Harold Gilliam "Comprehensive and copiously illustrated, this Guide is a treasure-house of user-friendly information. It reveals the equivalent of a national park hitherto unknown in our midst."—Margot Patterson Doss "This book is a complete guide to the Bay Area. All that's missing are the smells, so perhaps the next edition should be scratch and sniff."—Robin Williams
