This book was released on 2019 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Ficopomatus enigmaticus is a marine annelid invasive to many locations around the world. It was first identified as a non-indigenous species in San Francisco Bay, California in the 1920s, and since then it has been found in other parts of California. Because the full extent of the distribution of F. enigmaticus was unknown, I conducted surveys for the presence or absence of this species along the coast of California. Populations of F. enigmaticus were found at 23 of the 136 sites surveyed along the coast of California. Ficopomatus enigmaticus was found to be widespread in San Francisco Bay, Monterey Bay, and southern California.
Book Synopsis The Larval Dispersal of California Marine Invertebrates by : Henry S. Carson

Available in PDF, EPUB and Kindle. Book excerpt: Measuring the exchange of larvae is fundamental to understanding the population dynamics of marine organisms and designing effective management and restoration strategies for them. Population connectivity in the sea has been difficult to measure directly due to the small size and high mortality of marine larvae and their vast potential dispersal area. In three separate studies I examined larval dispersal in three groups of invertebrates on the California coast. The first study estimated the dispersal potential of 501 southern California bight polychaete species using known or inferred life-history characteristics, and related this potential to the species' distributions. Increased potential to disperse was related to higher occurrence frequencies in samples collected from soft-sediment habitats on the Channel Island shelves, but not on southern California mainland shelves. Channel Island polychaetes had lower dispersal potentials than their mainland counterparts, which may make Channel Island marine reserves comparatively more effective at maintaining local reproduction and, as a consequence, biodiversity. The second study explored the use of trace-elemental fingerprinting techniques to measure dispersal directly. These techniques have been previously utilized on larvae that retain calcified structures through development, such as fish or molluscs. We explored the use of trace-elemental fingerprinting on larvae that lack such structures. We found fine-scale chemical variation in porcelain crab embryos at 16 sites along 175 kilometers of coastline. This variation could potentially be used as a site- or region-specific fingerprint to assign settled porcelain crab larvae back to their point of origin. The third study employed trace-elemental fingerprinting to track the larvae of the Olympia oyster among four estuaries in southern California. Settled larvae collected at eight sites in 2007 were assigned to one of three source regions by comparing the chemistry of the portion of their shell formed during brooding with brooded shells collected at the same sites. Significant larval exchange occurred among all three regions separated by as many as 75 kilometers of coastline. The majority of recruits to San Diego Bay and two north San Diego County lagoons were self-recruits, and these two regions produced the majority of recruits to Mission Bay

Book Synopsis Biological Invasions in Marine Ecosystems by : Gil Rilov
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.

Book Synopsis Non-indigenous species in the Mediterranean and the Black Sea by : Food and Agriculture Organization of the United Nations
Download or read book Non-indigenous species in the Mediterranean and the Black Sea written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-07-29 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have seen significant changes in the biota of the Mediterranean and the Black Sea due to the introduction of non-indigenous species. Reliable scientific data on the dynamics of their distribution and abundance are essential to understand their ecological and economic effects. This review – in addition to providing images and descriptions of relevant species to aid in identification – presents a unique historical and regional perspective on these species’ impacts, based on many years’ worth of research. The Black Sea’s primary invaders come from the Mediterranean. Species like the comb jelly Mnemiopsis leidyi have caused major declines in biodiversity in the region by crippling key segments of the food chain. Similar results have been noted in the Marmara Sea, a crucial water exchange point located between the Aegean Sea and the Black Sea. Infiltration into the Mediterranean comes from both the east and west – with Lessepsian species passing through the Suez Canal and fish and invertebrate species originating from the Atlantic expanding their ranges. As of the publication of this review, over 900 non-indigenous species have been reported in the Mediterranean and almost 300 in the Black Sea, with these numbers expected to rise in the future. Numerous Lessepsian fishes are commercially relevant and have been absorbed into local markets, particularly in the eastern Mediterranean region. While these species are targeted through various fishing techniques, many others are simply discarded due to a lack of value and there are even some, such as lionfishes, pufferfishes and several species of jellyfishes, that present immediate dangers to human health. Stewardship of native species, regional cooperation on the enforcement of legal measures, increased public awareness and the creation of marine protected areas are thus essential to minimize and reduce the impacts of non-indigenous species both in the Mediterranean and the Black Sea.

The workshop "Baltic Coastal Ecosystems - Structure, Function and Coastal Zone Management" tried to provide an interdisciplinary forum for discussions, the exchange of ideas and the presentation of scientific results with respect to the Bal tic coast.
Book Synopsis Mudflat Ecology by : Peter G. Beninger
Download or read book Mudflat Ecology written by Peter G. Beninger and published by Springer. This book was released on 2019-02-13 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intertidal mudflats are distinct, highly-productive marine habitats which provide important ecosystem services to the land-sea interface. In contrast to other marine habitats, and despite a large body of primary scientific literature, no comprehensive synthesis exists, such that the scattered knowledge base lacks an integrated conceptual framework. We attempt to provide this synthesis by pulling together and contextualizing the different disciplines, tools, and approaches used in the study of intertidal mudflats. The editor pays particular attention to relationships between the various components of the synthesis, both at the conceptual and the operational levels, validating these relationships through close interaction with the various authors.
Book Synopsis Perspectives on the Marine Animal Forests of the World by : Sergio Rossi
Download or read book Perspectives on the Marine Animal Forests of the World written by Sergio Rossi and published by Springer Nature. This book was released on 2021-02-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Animal Forests (MAFs) are spread all over the world. Composed by suspension feeding organisms (e.g. corals, gorgonians, sponges, bryozoans, bivalves, etc.), MAFs constitute a vast number of marine ecosystems such as coral reefs, cold water corals, sponge grounds, bivalve beds, etc. The surface covered by these systems is prominent (at the scale of the oceans of the planet), though poorly known. In a previous book (Marine Animal Forests, the ecology of benthic biodiversity hotspots), several aspects of the MAFs were described and discussed, building the basis for a holistic approach with the aim of putting these shallow and deep sea ecosystems under a common umbrella. The main target of the present book is to identify and address important topics which were not covered in the previous three volumes. Bryozoans or Polychaeta, for example, are treated in this volume, as well as hydrothermal vents ecosystems and submarine caves, the chemical ecology in MAFs or the nursery effect on these ecosystems. The vastity of the MAF concept opens new insights in the biology, physiology, biodiversity of the organisms structuring these highly biodiverse ecosystems and on the dangers threatening them (such as microplastics or the role of invasive species as an impact of their trophic ecology or distribution). In a fast changing world, in which the complexity of MAFs is at risk, we propose an in-depth analysis of many aspects that may be inspirational for future research lines in marine biology and ecology.

This book was released on 2013-05-16 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: St Lucia is the world's oldest protected estuary and Africa's largest estuarine system. It is also the centerpiece of South Africa's first UNESCO World Heritage Site, the iSimangaliso Wetland Park, and has been a Ramsar Wetland of International Importance since 1986. Knowledge of its biodiversity, geological origins, hydrology, hydrodynamics and the long history of management is unique in the world. However, the impact of global change has culminated in unprecedented challenges for the conservation and management of the St Lucia system, leading to the recent initiation of a project in support of its rehabilitation and long-term sustainability. This timely volume provides a unique source of information on the functioning and management of the estuary for researchers, students and environmental managers. The insights and experiences described build on over 60 years of study and management at the site and will serve as a valuable model for similar estuaries around the world.
Book Synopsis Biological Invasions in South Africa by : Brian W. van Wilgen
Download or read book Biological Invasions in South Africa written by Brian W. van Wilgen and published by Springer Nature. This book was released on 2020-03-10 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Book Synopsis Operational and Environmental Consequences of Large Industrial Cooling Water Systems by : Sanjeevi Rajagopal
Download or read book Operational and Environmental Consequences of Large Industrial Cooling Water Systems written by Sanjeevi Rajagopal and published by Springer Science & Business Media. This book was released on 2012-01-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of water for industrial purposes is of foremost importance. It is used as a coolant and industrial activities dealing with power generation, steel and iron, paper and pulp and oil require very large amounts of water. The industry, therefore, resorts to large scale abstraction of water from natural water bodies. This water is often treated with chemicals to combat operational problems like biofouling and corrosion. Such withdrawal and subsequent discharge of large amounts of water have the potential to impart significant impact on the recipient water body. The organisms drawn along with the cooling water, as well as those residing at the discharge zone, are subjected to a combination of mechanical, thermal and chemical stress on a continuous basis.

Book Synopsis Handbook of Alien Species in Europe by : Delivering Alien Invasive Species
Download or read book Handbook of Alien Species in Europe written by Delivering Alien Invasive Species and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and assessment of biological invasions in the Pan-European region is finally possible. The Handbook of Alien Species in Europe summarises the major findings of this groundbreaking research and addresses the invasion trends, pathways, and both economic as well as ecological impact for eight major taxonomic groups. Approximately 11.000 alien species recorded in Europe are listed, and fact sheets for 100 of the most invasive alien species are included, each with a distribution map and colour illustration. The book is complemented by a regularly updated internet database providing free additional information. With its highly interdisciplinary approach, DAISIE and its Handbook will be the basis for future scientific investigations as well as management and control of alien invasive species in Europe.

Book Synopsis Closing the Knowledge-Implementation Gap in Conservation Science by : Catarina C. Ferreira
Download or read book Closing the Knowledge-Implementation Gap in Conservation Science written by Catarina C. Ferreira and published by Springer Nature. This book was released on 2022-01-03 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to synthesize the state of the art on biodiversity knowledge exchange practices to understand where and how improvements can be made to close the knowledge-implementation gap in conservation science and advance this interdisciplinary topic. Bringing together the most prominent scholars and practitioners in the field, the book looks into the various sources used to produce biodiversity knowledge - from natural and social sciences to Traditional Ecological Knowledge and Citizen Science - as well as knowledge mobilization approaches to highlight the key ingredients that render successful conservation action at a global scale. By doing so, the book identified major current challenges and opportunities in the field, for different sectors that generate, mobilize, and use biodiversity knowledge (like academia, boundary organizations, practitioners, and policy-makers), to further develop cross-sectorial knowledge mobilization strategies and enhance evidence-informed decision-making processes globally.
