Download or read book Krill written by Inigo Everson and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Krill, or euphausiids, a group of immense importance in marine ecosystems, comprises over 80 species, most of which are planktonic. Krill are widespread with species to be found in all the oceans of the world. Their numerical density in some regions increases their importance to marine ecosystems and has led to commercially successful krill harvesting. This comprehensive volume, thoroughly edited by Inigo Everson, well known for his work in this area, comprises chapters written by internationally acknowledged experts. The contents include coverage of: sampling and distribution, population, aggregation, reproduction and the role of krill in the ecosystem. Further specific chapters include krill harvesting, products and details of management in Japanese, Canadian and Southern Ocean waters. Drawing on the experience in each, the ecosystem approach to management is discussed in detail and how it might be applied more widely for example in forage fisheries. This most important volume draws together, for the first time, a vast amount of vital information for all those involved in work on these important marine organisms. Krill will be of great use to fisheries scientists, marine biologists and ecologists, oceanographers, zoologists and invertebrate biologists and all those involved in the commercial harvesting, exploitation and management of krill, world wide. Libraries in all aquatic and marine research stations and universities where marine and fisheries sciences are studied and taught should have multiple copies of this landmark publication on their shelves. Contributions from internationally-recognised experts in the field. Well-edited to provide an accessible and user-friendly book. Krill are a key part of ocean ecosystems. Part of exciting new Blackwell Science Series.

Download or read book Biology and Ecology of Antarctic Krill written by Volker Siegel and published by Springer. This book was released on 2016-08-03 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.

Book excerpt: Note that this book is based on Wikipedia and other public domain resources. Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name krill comes from the Norwegian word krill, meaning "young fry of fish", which is also often attributed to other species of fish. Krill are considered an important trophic level connection – near the bottom of the food chain – because they feed on phytoplankton and to a lesser extent zooplankton, converting these into a form suitable for many larger animals for whom krill makes up the largest part of their diet. In the Southern Ocean, one species, the Antarctic krill, Euphausia superba, makes up an estimated biomass of around 379 million tons, more than that of humans. Of this, over half is eaten by whales, seals, penguins, squid and fish each year, and is replaced by growth and reproduction. Most krill species display large daily vertical migrations, thus providing food for predators near the surface at night and in deeper waters during the day.

Download or read book Marine Biology a Very Short Introduction written by Philip Mladenov and published by Oxford University Press, USA. This book was released on 2020-02-27 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oceans are our planet's most distinctive and imposing natural habitat. They cover 71 percent of its surface; support a remarkably diverse and exquisitely adapted array of life forms, from microscopic viruses, bacteria, and plankton to the largest existing animals; and possess many of Earth's most significant, intriguing, and inaccessible ecosystems. In an era in which humans are significantly altering the global environment, the oceans are undergoing rapid and profound changes. The study of marine biology is thus taking on added importance and urgency as people struggle to understand and manage these changes to protect our marine ecosystems. Healthy oceans produce half of the oxygen we breathe; stabilize our climate; create ecosystems that protect our coasts from storms; provide us with abundant food; and host diverse organisms that provide us with natural products for medicine and biotechnology. In this Very Short Introduction, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun. Throughout the book he considers the human impacts on marine life including overfishing, plastic and nutrient pollution, the spread of exotic species, and ocean warming and acidification. He discusses the threats these pose to our welfare, and the actions required to put us on a path to a more sustainable relationship with our oceans so that they can be restored and protected for future generations. Mladenov concludes with a new chapter offering an inspiring vision for the future of our oceans in 2050 that can be realised if we are wise enough to accelerate actions already underway and be bold with implementing new approaches. The next decade will decide the state of the oceans that we leave behind for future generations.

Download or read book The Curious Life of Krill written by Stephen Nicol and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Scientists say they are one of most abundant animals on the planet. But when pressed, few people can accurately describe krill or explain their ecological importance. Antarctic krill have used their extraordinary adaptive skills to survive and thrive for millions of years in a dark, icy world far from human interference. But with climate change melting ice caps at the top and bottom of the world, and increased human activity and pollution, their evolutionary flexibility to withstand these new pressures may not be enough. Eminent krill scientist Stephen Nicol wants us to know more about this enigmatic creature of the sea. He argues that it's critical to understand krill's complex biology in order to protect them as the krill fishing industry expands. Ocean enthusiasts will come away with a newfound appreciation for the complex ecology of a species we have much to learn from, and many reasons to protect."--Provided by publisher.

Working Group 23 on Comparative Ecology of Krill in Coastal and Oceanic Waters around the Pacific Rim and published by . This book was released on 2013 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This final report from WG 23 contains summary reports from each PICES member country that highlight past and ongoing research on euphausiids (Section 3). Most countries do not have research projects specifically targeting euphausiids, so the data come from a variety of other sampling efforts which makes the amount of data available even more remarkable. Data from the North Pacific Continuous Plankton Recorder (CPR) survey (Section 4) are presented separately from the summary reports since they comprise samples from the waters of several PICES member countries. Modeling efforts used to parameterize euphausiids and explore their role in coastal and open-ocean food chains are discussed in Section 5. The last section highlights other successful activities of WG 23, including international collaborations and a protocol for conducting live experiments on euphausiids. The membership of WG 23 throughout its active period is listed in Appendix 1. The appendices also include a set of equations for converting among the different methods of measuring euphausiid length (Appendix 2) and an example of the questionnaire distributed to krill experts internationally (Appendix 3). More details of the working history of WG 23 can be found in its Annual Reports (Appendix 4) and the PICES Press article about the Krill Biology and Ecology Workshop held during the 2009 GLOBEC Open Science Meeting (Appendix 5)."--Page 1.
