Download or read book Biofouling written by Simone Dürr and published by John Wiley & Sons. This book was released on 2009-12-21 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofouling (the colonisation of an interface by a diverse array of organisms) is almost always a problem where it occurs, as it negatively affects surfaces, the materials that they are made from and the structures that they form, and can even destroy them. This comprehensive book covers in detail in its first section the processes involved in marine , freshwater and medical biofouling including coverage of settlement by larvae and spores, biofouling community processes, epibiosis (biofouling on living organisms) and microbial fouling, including biofilms deleterious to human health. The book's second section, encompassing biofouling processes with industrial implications, includes coverage of biofouling on artificial substrata, paints and coatings technology for the control of marine biofouling, biofouling and antifouling in the maritime industries, such as shipping, offshore oil , and aquaculture, and in power stations and other industries. The impacts of both biofouling and biofouling control and details of current legislation of relevance to biofouling issues are fully covered. The book's final section looks at methods for the measurement of biofouling, and future prospects for biofouling, including in-depth coverage of the changes anticipated in biofouling worldwide due to global climate change, and likely future directions in antifouling research, technology and legislation. Biofouling, which includes contributions from many international experts, is an essential reference for all those working in the antifouling industry including those involved in formulation of antifouling products such as paints and other coatings. Aquatic biologists, ecologists, environmental scientists and lawyers, marine engineers, aquaculture personnel, chemists, and medical researchers will all find much of interest within this book. All universities and research establishments where these subjects are studied and taught should have copies of this important work on their shelves.

Download or read book Historical and Oceanographic Influences on Phylogeography in the California Current Ecosystem and Applications to Management of Marine Species written by Alison Jane Haupt and published by Stanford University. This book was released on 2011 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overarching theme of my thesis is to explore patterns of larval dispersal as they relate to management of fished marine species. I employed a case study of two species: Megastraea undosa and Parastichopus parvimensis to investigate patterns of phylogeography and assess relative scales of dispersal for these two species which are fished in both California, USA and Baja California, MEX. To examine how some generalities for many species can be made for a specific geographic area, I reviewed all existing phylogeographic studies around Cape Mendocino, CA. Dispersal at a snail's pace: Strong genetic structure in the fisheries gastropod Megastaea undosa. Information about larval dispersal is necessary for effective management of fisheries. Population genetics are often employed to assess dispersal, but these data also carry artifacts from the evolutionary history of a species. I assessed historical and modern demography of the wavy top snail, Megastraea undosa, a marine snail that is fished in California, USA and Baja California, Mexico. Genetic structure at the COI mtDNA locus is strikingly high, with large shifts in haplotype frequencies between southern Baja and southern California. Coalescent-based modeling of genetic data suggests that the population has limited dispersal throughout the range and underwent a northward range expansion after the last glacial maximum. I conclude that both historical and contemporary processes affect observed patterns of phylogeography in M. undosa. Consideration of the evolutionary history of target species allows for a more accurate interpretation of genetic data for management. iv Subtle genetic structure in the commercially fished warty sea cucumber, Parastichopus parvimensis. The warty sea cucumber, P. parvimensis, is fished commercially in both California, USA and Baja California, Mexico but little is known about the status of the fisheries or if separate stocks exist. P. parvimensis has a long pelagic larval duration of 50-90 days, which may translate to high connectivity throughout the species range (Monterey, CA, USA to Bahía Asuncion, BCS, Mexico). I examined phylogeographic patterns at the COI mtDNA locus and five microsatellite loci throughout the range of P. parvimensis and was particularly interested in patterns associated with the potential phylogeographic barriers of Point Conception, CA, USA and Punta Eugenia, BCS, MEX. I found no structure associated with Point Conception, but subtle genetic structure at both types of loci for Punta Eugenia, which may be mechanistically explained by oceanographic patterns. These data have important implications for management of the sea cucumber fishery and indicate that populations south of Punta Eugenia likely do not receive biologically meaningful input of larvae from northern populations to supplement the local fishery. Concordant phylogeographic patterns associated with the major headland of Cape Mendocino in northern California. Most coastlines are non-linear and headlands such as Cape Mendocino may interact with oceanographic processes to create barriers to dispersal. Though Cape Mendocino is a prominent headland, it has been largely ignored in the phylogeographic literature, which focuses instead on Point Conception in southern California. I reviewed and synthesized phylogeographic studies that include sampling sites north and south of Cape Mendocino and discuss the v oceanography and topography of the cape as potential mechanistic drivers of larval dispersal patterns. Slightly more than half (24 out of 46) of the surveyed species that showed significant genetic structure around this headland, which suggests that this headland may be an important barrier to dispersal and may limit connectivity between northern and central California. If populations north of Cape Mendocino have higher connectivity with populations in Oregon than with those in central California, marine spatial planning must occur at a multi-state scale to reach marine conservation goals.

This book was released on 2011-06-16 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: A chapter on Staphylinidae in a 1976 book on marine insects was the last general work on coastal rove beetles worldwide. Since then, phylogenetic studies on rove beetles have yielded a different perspective on that family, now with well over 50,000 species. Almost 400 species of them are now believed to be restricted to sea coasts. The detailed distribution and current classification of the coastal species are here documented in a review of the world literature accompanied by discussion and numerous color photographs of habitus and habitat.

Download or read book Fishery Science written by Lee A. Fuiman and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now clear that data based on the studies of fish eggs and larvae make a number of unique contributions to fishery science that are crucial for accurate assessment and management of fish populations, including those of commercially important fisheries. This valuable book demonstrates why fish eggs and larvae are important, how the characteristics of early life stages require a somewhat different research approach and how information on early life stages can be applied and interpreted to yield unique insights into fish populations. The editors of Fishery Science have drawn together an extremely useful and well-written book with contributions from internationally respected researchers from North America, Asia and Europe. Chapters include a discussion of the unique nature of early life stages, age and growth, mortality, recruitment, populations analysis, habitats, human impacts and management. A carefully selected set of case studies demonstrates several specific applications of early life history information to a number of fishery problems. Fishery Science was designed to complement existing textbooks and is an essential purchase for all fisheries students and professionals, and for biologists working on the early life stages of fish. This exciting book is also of great value to ecologists, marine, freshwater and environmental scientists, populations biologists and oceanographers. All libraries in universities and research establishments where biological and fishery science are studied and taught should have copies of this book available on their shelves.

Download or read book Lagoons of Sri Lanka written by Silva, E. I. L. and published by IWMI. This book was released on 2013-03-01 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sri Lanka, an island in the Indian Ocean, has lagoons along 1,338 km of its coastline. They experience low-energy oceanic waves and semidiurnal microtidal currents. The Sri Lankan coastal lagoons are not numerous but they are diverse in size, shape, configuration, ecohydrology, and ecosystem values and services. The heterogeneous nature, in general, and specific complexities, to a certain extent, exhibited by coastal lagoons in Sri Lanka are fundamentally determined by coastal and adjoining hinterland geomorphology, tidal fluxes and fluvial inputs, monsoonal-driven climate and weather, morphoedaphic attributes, and cohesive interactions with human interventions.Most coastal lagoons in Sri Lanka are an outcome of mid-Holocene marine transgression and subsequent barrier formation and spit development enclosing the water body between the land and the sea. This process has varied from one coastal stretch to another due to wave-derived littoral drift, sediment transport by tidal fluxes, fluvial inputs and wave action or, in other words, sea-level history, shore-face dynamics and tidal range as the three major factors that control the origin and maintenance of the sandy barrier, the most important features for the formation and evolution of coastal lagoons with their landward water mass. In certain stretches of Sri Lanka’s coastline, formation of the barrier spit was very active due to shore-face dynamics that resulted in chains of shore parallel, elongated lagoons. They are among the most productive in terms of ecosystem yield and show some similarities to large tropical lagoons with respect to sea entrance, zonation, biodiversity and ecosystem services. However, some of them become seasonally hypersaline due to lack of freshwater input and high evaporation. Functions and processes of some of these water bodies are fairly known. There are a fair number of small back-barrier lagoons of different shapes and sizes whose origin goes back to sea-level history. They are located on low-energy coasts with prominent beach ridges and restricted hinterland geomorphology. Mixing processes of these landward indentations are hindered by elevated sand dunes, and their salinity increases due to poor freshwater input and high evaporation leading to seasonally hypersaline conditions. These sedimented lagoons, primarily confined to the southeastern coast of the island, are biologically the least productive, with limited ecosystem values and services. Another group of moderately elongated semicircular, slightly large lagoons in the same coast, formed exclusively by submergence due to mid-Holocene sea-level rises, do not receive sufficient freshwater input leading to seasonally hypersaline conditions. They are also biologically unproductive but some are ecologically important since they provide habitats conducive to migratory birds. In contrast, some lagoons on the southern coast receive sufficient freshwater via streams draining the wet zone, maintain more estuarine salinities, exhibit rich biodiversity and serve as functional resource units. Lagoons formed by mid-Holocene submergence and recession of water level with simultaneous chain barrier formation on the high energy southwest coast, which includes cliffs, small bays and headlands, show peculiar configurations and link channel characteristics. Some of these irregular water bodies have clusters of small isles and luxuriant mangrove swamps with high biodiversity but not very rich in catadromous finfish and shellfish species due to the restricted nature of the entrance channel and nondistinct salinity gradients. The barrier-built, seasonally hypersaline lagoon complex in the Jaffna Peninsula, the largest lagoon system in the country with multiple perennial entrances show extremely narrow salinity ranges towards the upper limit of salinity. The main lagoon is elongated and the shore parallel to eastward and southward extensions is connected by narrow channels. The other lagoon in the Jaffna Peninsula is elongated, shore parallel and ribbon-shaped and receives tidal water throughout the year but freshwater is received only from precipitation and surface runoff. Even though the lagoons in the peninsula are extremely rich in ecosystem heterogeneity their hydrology and hydrodynamics have been severely disturbed by infrastructural development for transportation and by attempts to create a freshwater river for Jaffna. There are a few virgin lagoons of moderate size also on the northern coast, south of the Jaffna Peninsula on both the east and west sides. They look very typical tropical lagoons rich in biodiversity and biological production but their structure, functions and values are virtually unknown in scientific or socioeconomic terms. The lagoons located on the east coast are not numerous but relatively large in extent. They are also an outcome not only of mid-Holocene sea-level rises but of submerged multi-delta valleys or abandoned paleo estuaries. When inundated, the multi-delta valley configuration became elongated and is shore parallel with a smooth seaward shoreline; both shorelines become irregular when coastal waves are weak, and internal waves are created by the action of local winds. Configuration of a lagoon formed by inundation of an abandoned river valley is irregular with a long entrance channel extended landward. These lagoons are highly productive with a variety of associated ecosystems, large open water areas and wide perennial sea entrances. When the lagoon is too much elongated, zonation is prominent due to fewer entrance effects. Lagoons form a particular type of natural capital which generates use values (fish, shrimp, fuelwood, salt, fodder, ecotourism, anchorage, recreation, etc.) and nonuse values (habitat preservation, biodiversity, ecosystem linkages, etc.) contributing positively towards improving the human well-being. Of many values of lagoons in Sri Lanka, only the extractive values are generally utilized at present, by way of fish and shrimp catches, salt production and use of mangrove for various purposes. Besides, coastal lagoons generate a range of nonextractive use values and nonuse values, which could add towards the total economic value. Misuse has taken place at several instances when “use” adversely affects the status of the resources or the health of the ecosystem due to vulnerability and poverty, population pressure, urbanization, development activities and multi-stakeholder issues. The status of lagoon resources shows that the resources in the majority of Sri Lankan lagoons still remain satisfactory, somewhat good or very good. Nevertheless, concerns for management of lagoons in Sri Lanka exist only where “use values” (extractive values, such as fish and shrimp) exist. There is no evidence of resources management in lagoons for inspirational, scholarly values or tacit knowledge of the same. Management for use values exhibits several stages from zero management to comanagement via community management and state intervention. Most of Sri Lanka’s lagoons have the potential for generating high extractive and nonextractive use values which could improve the human well-being, while maintaining resources sustainability. Unfortunately, these potentials have not been understood or “seen” yet by the relevant authorities, although a few instances of exploring this potential were noticed.

Download or read book Sandy Beaches as Ecosystems written by A. McLachlan and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: What sight is more beautiful than a high-energy beach facing lines of rolling white breakers? What battleground is more ferocious than where waves and sand meet? What environment could be more exciting to study than this sandy interface between sea and land? And yet how much do we know about sandy beaches? Open sandy beaches are amongst the most neglected fields of scientific study in the coastal environment. This situation exists despite their great extent along most temperate and tropical coastlines and their value as recreational areas and buffer zones against the sea. The traditional oceanographer does not venture into the surf zone while the terrestrial ecologist stops short at the high water mark. Only a few coastal engineers have grappled with the problem of sand and sediment movement as it influences their construction of harbours and pipelines. The marine biologist on the other hand has regarded estuaries, coral reefs and rocky shores, obviously teeming with life, as more fruitful areas for study than the apparently poor animal life on sandy beaches. Sandy beaches have therefore tended to become a scientific no man's land. Over the last decade this situation has begun to improve. Recent work on high-energy beaches has revealed that they may in fact be rich and productive and fertile areas for study. It has even been suggested that beaches and their adjacent surf zones may constitute viable marine ecosystems.
