Download or read book Biological Invasions in Marine Ecosystems written by Gil Rilov and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.

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.
Download or read book Marine Bioinvasions Patterns Processes and Perspectives written by Judith Pederson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the global rate of marine introductions increases, exotic species exert greater economic and ecological impacts, affecting ecosystems and human health. The complexity of marine ecosystems challenges our ability to find easy solutions to prevention, management, and control of introductions. This book highlights issues of timely importance in marine bioinvasion science. Selected topics explore the potential evolutionary consequences and ecological impacts of introduced organisms, examine the feasibility of biological control, and describe patterns of introduction. These papers were presented at the Second International Conference on Marine Bioinvasions, which featured new marine invasion research from around the world. These papers should be of interest to scientists, students, and managers with an interest in marine bioinvasions and the application of knowledge to management concerns.

Book excerpt: Estuarine and coastal ecosystems face both large scale physical environmental stresses from climate change and local scale community changes, including non-native species introductions. In northern California, USA, climate change projections indicate increasingly severe droughts in the future punctuated by more frequent, intense winter storms, significantly affecting freshwater outflow to estuaries like San Francisco Bay. Using long-term physical and biological data sets coupled with experiments, I found drastic changes in epifaunal communities in the Bay between years with extreme high and low freshwater outflow (Chapter 1). In dry years (low outflow), competition determines community composition, but in wet years (high outflow), low salinity stress shifts the community to being recruitment limited, with community membership determined by the availability of larvae to recruit. Shifts in outflow extremes drive changes in the dominant species, resulting in altered community performance (Chapter 2). I experimentally tested the effect of functional group diversity on community performance in different outflow regimes. Communities containing more functional groups generally occupied more space, but the strength of this effect varied from year to year. In the absence of normally dominant species during a wet year, resident community functional group diversity had no effect on subsequent invasion by non-resident species. These results suggest that outcomes of short-term, unreplicated studies of biodiversity-ecosystem function relationships may thus be contingent on prevailing conditions. Finally, I assessed the risk posed by the aquarium fish trade for introducing non-native fish species to the San Francisco Bay-Delta using an inventory of fish species for sale, a model comparing fish physiological tolerances to environmental parameters, and a telephone survey of store representatives' knowledge and attitudes toward invasions (Chapter 3). This analysis showed that the local aquarium trade includes at least five and as many as twenty-seven species that could potentially survive in the Bay-Delta. Management efforts for this vector should focus on improving labeling and identification of fish species in stores, expanding available information on fish physiological tolerances, educating customers and store employees about the risks of pet release, and providing better options for responsible disposal of unwanted fish.

Available in PDF, EPUB and Kindle. Book excerpt: Who Speaks for the Oceans? The question has been asked a lot in recent years - just who is looking out for our oceans? Covering over seventy percent of the earth's surface it is the world's largest common property resource,jojntly owned by over six billion humans. It is the foundation for life on earth as we know it. Over the years, many people have spoken about various aspects of our ocean environments and they have spoken to different audiences in many different ways. For many in the public realm, Jacques Cousteau spoke for the ocean. Since his passing, no single voice with the sallle public identity or recognition has emerged. Certainly the many governments bordering our oceans cannot agree on common principles or issues of ocean use and management. We might be tempted think that we do not have an ocean spokesperson or champion, but we would be wrong. Today, the rapidly growing number of scientists working hard to expand our under standing of our ocean realm are the ocean voices we should listen to. At the same time as our scientists advance their understanding of the oceans, we all need to advance our abilities and commitment to communicate on behalf of the oceans with broader and broader audiences who need to be aware of where things stand. Often called "the last great frontier", earth's oceans are vast, widely varied, and are hard to get to, arid into, to do the research we need done.
