Available in PDF, EPUB and Kindle. Book excerpt: Tidal marshes are considered one of the most productive fish habitats in the world, yet how they support economically, recreationally, and ecologically valuable species in the San Francisco Estuary remains unclear. A major factor contributing to this uncertainty is extensive tidal marsh loss along the shorelines of San Francisco Bay and in the upstream Sacramento-San Joaquin Delta ("Delta"). Located in between the bay and the Delta, Suisun Marsh is a large network of tidal sloughs, tidal marshes, managed tidal ponds, and uplands that serves as a regional stronghold for a diverse fish assemblage. Understanding how Suisun Marsh supports such fishes is paramount for informing restoration throughout not only the San Francisco Estuary, but estuaries worldwide. The first chapter of this dissertation uses long-term fish-monitoring data to examine Suisun Marsh's role as a fish nursery for resident and transient fishes. Young-of-year Sacramento splittail (Pogonichthys macrolepidotus), tule perch (Hysterocarpus traskii), and striped bass (Morone saxatilis) were abundant in shallow interior sloughs hydrologically connected to tidal marshes, managed tidal ponds, and/or uplands; in contrast, starry flounder (Platichthys stellatus) were abundant in deeper, flow-through sloughs closer to the open estuary. Habitat complexity and freshwater flows were major drivers of nursery function. The second chapter describes resident and transient fish movements in an intertidal channel located in the largest natural tidal marsh in Suisun Marsh. The resident tule perch consistently spent more time per visit, per day, and per season using the intertidal channel, whereas the transient splittail and striped bass were more opportunistic and exhibited higher individual variation in movement patterns. Tides were important to tule perch and striped bass, whereas moon phase was important to splittail. The third chapter examines fish feeding guilds (planktivores, benthivores, piscivores) across a natural tidal marsh elevation gradient. Tides structured distributions of guilds across the elevation gradient and likely influenced foraging and predator avoidance strategies. Macrozooplankton and benthic macroinvertebrates were common prey items in fish stomachs and highlighted the importance of propagating diverse food web pathways to fishes in tidal marshes. Collectively, these chapters show that resident and transient fishes are adapted to using Suisun Marsh's mosaic of habitats at the land-water interface as nursery habitat and for food and refuge.

This book was released on 2012-09-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Francisco Bay, the biggest estuary on the west coast of North America, was once surrounded by an almost unbroken chain of tidal wetlands, a fecund sieve of ecosystems connecting the land and the Bay. Today, most of these wetlands have disappeared under the demands of coastal development, and those that remain cling precariously to a drastically altered coastline. This volume is a collaborative effort of nearly 40 scholars in which the wealth of scientific knowledge available on tidal wetlands of the San Francisco Estuary is summarized and integrated. This book addresses issues of taxonomy, geomorphology, toxicology, the impact of climate change, ecosystem services, public policy, and conservation, and it is an essential resource for ecologists, environmental scientists, coastal policymakers, and researchers interested in estuaries and conserving and restoring coastal wetlands around the world.

Available in PDF, EPUB and Kindle. Book excerpt: One of California's most remarkable wetlands, Suisun Marsh is the largest tidal marsh on the West Coast and a major feature of the San Francisco Estuary. This productive and unique habitat supports endemic species, is a nursery for native fishes, and is a vital link for migratory waterfowl. The 6,000-year-old marsh has been affected by human activity, and humans will continue to have significant impacts on the marsh as the sea level rises and cultural values shift in the century ahead. This study includes in-depth information about the ecological and human history of Suisun Marsh, its abiotic and biotic characteristics, agents of ecological change, and alternative futures facing this ecosystem.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of salt marsh has caused the decline of many aquatic organisms which depend on marshes to provide critical ecosystem functions such as spawning habitat, nursery habitat, and food resources. There are currently many restoration efforts in coastal salt marshes taking place worldwide to redress the loss of this habitat. In San Francisco Estuary, one of the largest salt marsh restoration projects is the South Bay Salt Pond Restoration Program, which aims to return up to 61 km2 of salt production ponds to tidal habitat. We examined patterns in the distribution of fishes and invertebrates to determine how they responded to restoration actions. The results show a rapid positive response; within the first several years the restored tidal habitats were used by 40 species of fish and many species of invertebrates. The restored areas supported most members of the local fish and invertebrate community. We found no discernable differences in the physicochemical habitat between pre-existing slough habitat and newly breeched restoration sites. Most variability in community structure was attributed to seasonal changes and not to spatial patterns of landscape attributes. This study supports the assertion that salt marsh restoration can have rapid benefits to estuarine-dependent biota, including imperiled species.

This book was released on 2000-10-31 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tidal salt marshes are viewed as critical habitats for the production of fish and shellfish. As a result, considerable legislation has been promulgated to conserve and protect these habitats, and much of it is in effect today. The relatively young science of ecological engineering has also emerged, and there are now attempts to reverse centuries-old losses by encouraging sound wetland restoration practices. Today, tens of thousands of hectares of degraded or isolated coastal wetlands are being restored worldwide. Whether restored wetlands reach functional equivalency to `natural' systems is a subject of heated debate. Equally debatable is the paradigm that depicts tidal salt marshes as the `great engine' that drives much of the secondary production in coastal waters. This view was questioned in the early 1980s by investigators who noted that total carbon export, on the order of 100 to 200 g m-2 y-1 was of much lower magnitude than originally thought. These authors also recognized that some marshes were either net importers of carbon, or showed no net exchange. Thus, the notion of `outwelling' has become but a single element in an evolving view of marsh function and the link between primary and secondary production. The `revisionist' movement was launched in 1979 when stable isotopic ratios of macrophytes and animal tissues were found to be `mismatched'. Some eighteen years later, the view of marsh function is still undergoing additional modification, and we are slowly unraveling the complexities of biogeochemical cycles, nutrient exchange, and the links between primary producers and the marsh/estuary fauna. Yet, since Teal's seminal paper nearly forty years ago, we are not much closer to understanding how marshes work. If anything, we have learned that the story is far more complicated than originally thought. Despite more than four decades of intense research, we do not yet know how salt marshes function as essential habitat, nor do we know the relative contributions to secondary production, both in situ or in the open waters of the estuary. The theme of this Symposium was to review the status of salt marsh research and revisit the existing paradigm(s) for salt marsh function. Challenge questions were designed to meet the controversy head on: Do marshes support the production of marine transient species? If so, how? Are any of these species marsh obligates? How much of the production takes place in situ versus in open waters of the estuary/coastal zone? Sessions were devoted to reviews of landmark studies, or current findings that advance our knowledge of salt marsh function. A day was also devoted to ecological engineering and wetland restoration papers addressing state-of-the-art methodology and specific case histories. Several challenge papers arguing for and against our ability to restore functional salt marshes led off each session. This volume is intended to serve as a synthesis of our current understanding of the ecological role of salt marshes, and will, it is hoped, pave the way for a new generation of research.

This book was released on 2007-05-08 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1968 when I forsook horticulture and plant physiology to try, with the help of Sea Grant funds, wetland ecology, it didn’t take long to discover a slim volume published in 1959 by the University of Georgia and edited by R. A. Ragotzkie, L. R. Pomeroy, J. M. Teal, and D. C. Scott, entitled “Proceedings of the Salt Marsh Conference” held in 1958 at the Marine Institute, Sapelo Island, Ga. Now forty years later, the Sapelo Island conference has been the major intellectual impetus, and another Sea Grant Program the major backer, of another symposium, the “International Symposium: Concepts and Controversies in Tidal Marsh Ecology”. This one re-examines the ideas of that first conference, ideas that stimulated four decades of research and led to major legislation in the United States to conserve coastal wetlands. It is dedicated, appropriately, to two then young scientists – Eugene P. Odum and John M. Teal – whose inspiration has been the starting place for a generation of coastal wetland and estuarine research. I do not mean to suggest that wetland research started at Sapelo Island. In 1899 H. C. Cowles described successional processes in Lake Michigan freshwater marsh ponds. There is a large and valuable early literature about northern bogs, most of it from Europe and the former USSR, although Eville Gorham and R. L. Lindeman made significant contributions to the American literature before 1960. V. J.

Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.
