Available in PDF, EPUB and Kindle. Book excerpt: Tidal wetland ecosystems are dynamic coastal habitats that, in California, often occur at the complex nexus of aquatic environments, diked and leveed baylands, and modified upland habitat. Because of their prime coastal location and rich peat soil, many wetlands have been reduced, degraded, and/or destroyed, and yet their important role in carbon sequestration, nutrient and sediment filtering, flood control, and as habitat requires us to further research, conserve, and examine their sustainability, particularly in light of predicted climate change. Predictions of regional climate change effects for the San Francisco Bay Estuary present a future with reduced summer freshwater input and increased sea levels, resulting in higher estuarine salinities throughout the growing season, increased saline influence in brackish and freshwater marshes, and increased depth and duration of inundation. Experimentally testing, monitoring across scales, and spatially modeling the responses of dominant wetland vegetation to the substantial predicted climate change effects are among the critical threads of knowledge needed to understand how this estuary and others along the Pacific coast might respond to significant changes in physical drivers and community interactions. My dissertation research focused on possibilities for wetland resilience in a changing climate in the San Francisco Bay Estuary across scales and using a suite of methodologies. Tidal wetland resilience to predicted sea-level rise requires an understanding of both individual plant and community-level responses in addition their interactions with sediment supply and adjacent land uses. Through a large field experiment simulating sea-level rise, I found that wetland plants have a high tolerance for increases in inundation in the short term and that community interactions need to be incorporated into plant responses to increased sea-level rise. Scaling measurements of plant production up to the site level and across landscapes requires the integration of field measurements with remotely sensed measurements. Investigating remote sensing techniques of measuring carbon stock, I found that the presence of dense standing plant litter common in Pacific coast freshwater wetlands can hinder the ability to find a reliable way of measuring plant production remotely. Finally, I was able to successfully calibrate an ecogeomorphic mechanistic model for wetland accretion across four wetlands in the San Francisco Bay Estuary and examine potential wetland resiliency under a range of sea-level rise scenarios. At sea-level rise rates 100 cm/century and lower, wetlands remained vegetated. Once sea levels rise above 100 cm, marshes begin to lose ability to maintain elevation, and the presence of adjacent upland habitat becomes increasingly important for marsh migration. Results from this study emphasize that the wetland landscape in the bay is threatened with rising sea levels, and there are a limited number of wetlands that will be able to migrate to higher ground as sea levels rise. Despite these challenges, my dissertation presents a robust and new understanding of how tidal wetlands might respond to predicted climate change.

This book was released on 2012-10-09 with total page 289 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.

Book excerpt: The resilience of San Francisco Bay shore habitats, such as tidal marshes and mudflats, is essential to all who live in the Bay Area. Tidal marshes and tidal flats (also known as mudflats) are key components of the shore habitats, collectively called baylands, which protect billions of dollars of bay-front housing and infrastructure (including neighborhoods, business parks, highways, sewage treatment plants, and landfills). They purify the Bay's water, support endangered wildlife, nurture fisheries, and provide people access to nature within the urban environment. Bay Area residents showed their commitment to restoring these critical habitats when they voted for a property tax to pay for large-scale tidal marsh restoration. However, climate change poses a great threat, because there may not be enough natural sediment supply for tidal marshes and mudflats to gain elevation fast enough to keep pace with sea-level rise. This report analyses current data and climate projections to determine how much natural sediment may be available for tidal marshes and mudflats and how much supplemental sediment may be needed under different future scenarios. These sediment supply and demand estimates are combined with scientific knowledge of natural physical and biological processes to offer a strategy for sediment delivery that will allow these wetlands to survive a changing climate and provide benefits to people and nature for many decades to come. The approach developed in this report may also be useful beyond San Francisco Bay because shoreline protection, flood risk-management, and looming sediment deficits are common issues facing coastal communities around the world.

Download or read book Interpretation and Implications of Variability in Ecological Systems written by Robert Klinger and published by Frontiers Media SA. This book was released on 2024-07-22 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous hypotheses have been proposed to explain the dynamics in abundance of individual species, how species interact, how communities assemble, and how interactions between biotic and abiotic processes shape ecosystem stability. Many if not most of these hypotheses find some degree of support, but often only within relatively narrow spatial and temporal ranges. This is because conditions vary over time and from place to place, and so the strength and extent of processes that were the focus of a given a hypothesis become altered by other forces. Ecologists have confronted variability from two perspectives; conceptual and statistical. Conceptually, spatial and temporal variability are now recognized as being scale dependent and hierarchical. Statistically, there are many models that ecologists readily use that account for the hierarchical and scale-dependence of variability present in many datasets. But linking the two perspectives into a meaningful understanding of what variability means in real systems has been much less successful. For example, it is common to see studies where the fixed effects of a generalized linear mixed model are reported, but very often random effects are completely ignored or, at best, given scant attention. The likelihood of this being a significant problem increases greatly in what are rapidly becoming more common studies that utilize datasets spanning long temporal and/or large spatial scales, or when extreme and often unpredictable events (gray and black swans) occur.
