This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Download or read book Stratigraphic Paleobiology written by Mark E. Patzkowsky and published by University of Chicago Press. This book was released on 2012-03-12 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether the fossil record should be read at face value or whether it presents a distorted view of the history of life is an argument seemingly as old as many fossils themselves. In the late 1700s, Georges Cuvier argued for a literal interpretation, but in the early 1800s, Charles Lyell’s gradualist view of the earth’s history required a more nuanced interpretation of that same record. To this day, the tension between literal and interpretive readings lies at the heart of paleontological research, influencing the way scientists view extinction patterns and their causes, ecosystem persistence and turnover, and the pattern of morphologic change and mode of speciation. With Stratigraphic Paleobiology, Mark E. Patzkowsky and Steven M. Holland present a critical framework for assessing the fossil record, one based on a modern understanding of the principles of sediment accumulation. Patzkowsky and Holland argue that the distribution of fossil taxa in time and space is controlled not only by processes of ecology, evolution, and environmental change, but also by the stratigraphic processes that govern where and when sediment that might contain fossils is deposited and preserved. The authors explore the exciting possibilities of stratigraphic paleobiology, and along the way demonstrate its great potential to answer some of the most critical questions about the history of life: How and why do environmental niches change over time? What is the tempo and mode of evolutionary change and what processes drive this change? How has the diversity of life changed through time, and what processes control this change? And, finally, what is the tempo and mode of change in ecosystems over time?

Book excerpt: IN 1998, SCIENTISTS representing more than fifty international research organizations met to seek answers to environmental questions regarding pollution, ocean cleansing, and the impact that changes in sediment layers have on benthic organisms and the ecosystems that depend on them. Their findings consider these topics, identify opportunities for future investigations, and promote active partnerships between federal regulatory agencies and the academic community in order to preserve and enhance natural aquatic resources.

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.
