This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Variability in annual recruitment for many fishes is correlated with survival during the larval phase. Yellow perch in Lake Michigan have experienced sustained recruitment failure since 1990 and this has been blamed on low larval survival. Direct examination of factors important to larval yellow perch survival in Lake Michigan is complicated by the large size of the lake (52,000 km2) and the short length of the pelagic larval period (30-40 days). Individual-based modeling is a valuable indirect method for assessing the importance of multiple factors to larval survival. I used an individual-based modeling approach combined with field data collection to test four hypotheses regarding factors limiting survival of larval yellow perch in Lake Michigan. I tested whether larval survival is limited by prey community composition, size-selective predation, advection of larvae into offshore habitat or an interaction of these factors. I sampled larval and zooplankton abundance in Lake Michigan along a transect from 1 - 32 km from shore in 2000 and 2001. I conducted laboratory experiments to quantify larval vulnerability to predation by three typical predators as a function of both predator and prey size. I also conducted laboratory experiments to quantify larval selectivity for different zooplankton prey as a function of larval size and prey community composition. I used the results of these experiments to develop an individual-based model specifically to describe growth and survival of larval yellow perch. Field data suggest that larval yellow perch are being transported from the nearshore to the offshore zone of Lake Michigan, but the timing of this transport varies between years. Model simulations in which the offshore prey community and the timing of larval advection were both varied suggested that larval survival will be highest in years when advection occurs within two weeks of peak hatch, allowing larvae to exploit offshore prey resources early during ontogeny. The.

Available in PDF, EPUB and Kindle. Book excerpt: This volume, cataloging and analyzing the current science on the state of Lake Michigan, is an important part of Great Lakes recovering science. It carries forward the singular contribution that the binational Great Lakes scientific community has made not only to restoring the Great Lakes but also to the world's body of knowledge about large lake ecology, the long-range transport of pollutants, and the importance of habitat in ensuring ecosystem health.
Download or read book Invasive Aquatic Species of Europe Distribution Impacts and Management written by Erkki Leppäkoski and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global scale of alien species invasions is becoming more and more evident in the beginning ofthe new millennium. Though the problem ofbiological invasions became a rapidly growing research area, there are large gaps still, both geographically and the matically, to be filled in the near future. This book is the first attempt to provide an overall picture of aquatic species invasions in Europe. Its geographical scope stretches from Irish waters in the west to Volga River and the Caspian Sea in the east, and from Mediterranean in the south up to the Arctic coast of Europe. Not all parts of the continent could be equally covered, as in some countries species invasions are not studied yet. The book tends to represent the array of all major European aquatic systems on the broadest geographical and ecological scope possible from fully saline seas, semi-enclosed brackish water bodies and coastallagoons to freshwater lakes, major river systems and waterways. The key objectives include the present status and impacts caused by non-native aquatic species in European waters. Please note that lengthy species lists submitted for publication and additional informa tion were put on the Internet, as the electronical version of these tables benefits from computer assisted search for data (http://www. ku. lt/nemo/EuroAquaInvaders. htm). Altogether more than 100 scientists from 24 countries have joined to synthesize the available information on bioinvasions. However, the book does not claim to be fully comprehensive.

Download or read book Ecology written by Charles J. Krebs and published by Benjamin-Cummings Publishing Company. This book was released on 2001 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.
Download or read book Lake Erie and Lake St Clair Handbook written by S. J. Bolsenga and published by Wayne State University Press. This book was released on 1993 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn about the wonders of Lake Erie and Lake St. Clair in this fascinating and readable book. The most comprehensive reference source available about the lakes, Lake Erie and Lake St. Clair Handbook is an ideal guide for anglers, boaters, swimmers, beach walkers—anyone who uses and enjoys the lakes. The handbook explains, in simple terms, the reasons for the scenic beauty and the natural events that occur in the coastal and offshore waters of Lake Erie and Lake St. Clair, including the St. Clair, Detroit, and Niagara rivers extending from Sarnia, Ontario, to Niagara-on-the-Lake, New York. Individual chapters focus on the land, air, water, and life forms that comprise the natural history and environment of the region—the shoreline topography, wind and weather patterns, water temperature cycles and water level changes, the ecology, and indigenous animal life. Lake Erie and Lake St. Clair Handbook enhances our understanding and appreciation of the lakes and their surroundings by addressing fundamental questions about the Lake Erie region: • how Lake Erie was formed through glacial processes • why daily and seasonal weather patterns occur • causes of the water currents and waves • causes of temperature patterns in the lakes • the location of productive reef features • the species of fish and birds found in the area • the importance of the wetlands • the effect of current and past pollution on the aquatic life in the lakes

This book was released on 2014-04-05 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.
