Book Description
"Vernal pools in the Northeastern United States are small, forested wetlands characterized by ephemeral flooding. These unique ecosystems provide critical habitat for both terrestrial and aquatic organisms, abate seasonal flooding, and are biogeochemical hotspots. Vernal pools may be created to maintain key ecosystem services associated with loss of natural wetlands. In many instances, however, created pools do not mimic the ecological functions and services of extant vernal pools due to shortcomings associated with the surrounding land use and canopy cover, hydrology, or invasion by opportunistic plants. Because of the importance of these systems to regional biodiversity, understanding the conditions required for adequate restoration of ecosystem function is imperative. The goal of this thesis was to determine differences in physico-chemical and biological properties between created and natural wetlands and to experimentally manipulate light availability and litter input in created pools to evaluate the importance of canopy cover in establishing desired ecosystem functions in created vernal pools. This study took place in natural (n=4) and created (n=8) vernal pools at High Acres Nature Area in Perinton, NY. Natural pools received over three times more carbon input from leaf litter and had greater light availability than created pools. The macroinvertebrate and plant communities were also markedly different, with a striking lack of invasive plants in natural pools. There were no significant differences in soil phosphorous or ammonium, but there were differences in surface water concentrations of the respective nutrients. Invasive species regrowth was limited in pools with experimental canopy shade, suggesting the potential for artificial canopy cover to limit invasion by undesirable plants, help to promote biodiversity, and aid in successful wetland restoration."--Abstract.

Book Description
“Wetland Habitats of North America is essential reading for everyone who studies, manages, or visits North American wetlands. It fills an important void in the wetland literature, providing accessible and succinct descriptions of all of the continent’s major wetland types.” Arnold van der Valk, Iowa State University “Batzer and Baldwin have compiled the most comprehensive compendium of North American wetland habitats and their ecology that is presently available—a must for wetland scientists and managers.” Irving A. Mendelssohn, Louisiana State University "If you want to gain a broad understanding of the ecology of North America’s diverse wetlands, Wetland Habitats of North America is the book for you. Darold Batzer and Andrew Baldwin have assembled an impressive group of regional wetland scientists who have produced a virtual encyclopedia to the continent’s wetlands. Reading the book is like a road trip across the Americas with guided tours of major wetland types by local experts. Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Then you’ll travel inland where you can visit any or all of 18 types ranging from bottomland swamps of the Southeast to pothole marshes of the Northern Prairies to montane wetlands of the Rockies to tropical swamps of Central America and desert springs wetlands. All in one book—I’m impressed! Every wetlander should add this book to her or his swampland library. Ralph Tiner, University of Massachusetts–Amherst

Book Description
This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
