Termin realizacji zamówienia: ok. 5-8 dni roboczych. 2 In China, there are more than 2,759 lakes with surface area greater than 1km, and 2 the total lake area is 91,019km . One-third of these lakes are freshwater lakes, and the majority are situated in the middle and lower reaches of the Changjiang River or in eastern China s coastal areas. These lakes function as drinking water supplies, ood control systems, aquaculture and tourism resources, navigation channels, etc. Recently, many shallow lakes in China have been subject to rapid eutrophication and suffer from algal blooms. This issue has resulted in a shortage of drinking water and in...

Aquaculture, Innovation and Social Transformation
ISBN: 9781402088346 / Angielski / Twarda / 346 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the green revolution before it, the blue revolution in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002;...

ISBN: 9780807085691 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Perched on the banks of Stony Brook in the Cape Cod town of Brewster, Hay observes the stunning phenomenon of the annual run of the alewife, a herring that spawns in fresh water, enters the ocean as a fingerling, and returns to its natal pond. From the Gulf of St. Lawrence to the Carolina's, hordes of alewives make the dramatic journey every Spring. For Hay, the run is filled with danger and beauty: "In terrible simplicity, the alewives were swimming toward the island gauntlet they would have to run, having a title, by their common, wild, and ancient advent, to all great kindled things."

The Behavior and Sensory Biology of Elasmobranch Fishes: An Anthology in Memory of Donald Richard Nelson
ISBN: 9780792368212 / Angielski / Twarda / 320 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The elasmobranch fishes include the living sharks, skates and rays that are important members of nearly all marine ecosystems. Their large size, secretive behavior, and wide-ranging habits make them difficult to observe in the field or to maintain in captivity. Consequently, little is known about their natural behavior and how it is mediated by their sensory systems. This volume is dedicated to the scientific contributions and memory of Donald Nelson, a pioneer in the study of shark behavior, sensory biology, and remote instrumentation. The two opening papers review Don Nelson's unique...

Color of Inland and Coastal Waters: A Methodology for Its Interpretation
ISBN: 9783540002000 / Angielski / Twarda / 170 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The inorganic and organic water constituents, often called color-producing agents (CPAs), responsible for water color are generally referred to as water quality parameters. Utilization of water color for assessment of water quality parameters can be achieved by using the established techniques in aquatic optics attained over many decades. Aquatic optics can be subdivided according to whether the natural water body is salty (marine), inland or fresh (limnological), or coastal (often brackish). The authors describe the transformation of water color under varying natural and...

Eutrophication in Coastal Ecosystems: Towards Better Understanding and Management Strategies: Selected Papers from the Second International Symposium
ISBN: 9789048133840 / Angielski / Twarda / 264 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Coastal eutrophication has been and still remains an important issue for the scientific community. Despite many efforts to mitigate coastal eutrophication, the problems associated with eutrophication are still far from being solved. This book focusses on the most recent scientific results in relation to specific eutrophication issues, e.g. definition(s) and causes; nutrient loads, cycling and limitation; reference conditions, primary effects and secondary effects; trend reversal (oligotrophication), as well as links to other pressures (climate change and top/down control). It also focusses... Coastal eutrophication has been and still remains an important issue for the scientific community. Despite many efforts to mitigate coastal eutroph... |
