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.

This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources. Better knowledge in this regard is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. As a follow-up on a recommendation by the IOC Program Group for the Southern Oceans made in March 1983, the Intergovernmental Oceanographic Commission organized a meeting of experts on oceanography related to the dynamics of the Antarctic ecosystems. During this meeting, held in Kiel, Federal Republic of Ger many, in May 1984, biologists and oceanographers involved in BIOMASS activities met with the oceanographers of SCOR Working Group 74 to discuss ways and means for additional physical and chemical observations in the oceanographic research within BIOMASS. It was the time when large fluctuations in the distribution of krill with subsequent detrimental effects on predator species dependent on krill had just been observed, and the question arose whether this was possibly the result of changes in the Antarctic water circulation.

Download or read book The Curious Life of Krill written by Stephen Nicol and published by Island Press. This book was released on 2018-05-08 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Makes you feel as if you're part of an engaging dinnertime conversation." --Science News Krill. It's a familiar word that conjures oceans, whales, and swimming crustaceans. Scientists say they are one of most abundant animals on the planet. But few can accurately describe krill or explain their ecological importance. Eminent krill scientist Stephen Nicol wants us to know more about these enigmatic creatures and how we can protect them as Antarctic ice melts. This engaging account takes us to the Southern Ocean to learn firsthand the difficulties and rewards of studying krill in their habitat. From his early education about the sex lives of krill in the Bay of Fundy to a krill tattoo gone awry, Nicol uses humor and personal stories to bring the biology and beauty of krill alive.
Download or read book The Social Lives of Animals written by Ashley Ward and published by Basic Books. This book was released on 2022-03-01 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rat will go out of its way to help a stranger in need. Lions have adopted the calves of their prey. Ants farm fungus in cooperatives. Why do we continue to believe that life in the animal kingdom is ruled by competition? In The Social Lives of Animals, biologist Ashley Ward takes us on a wild tour across the globe as he searches for a more accurate picture of how animals build societies. Ward drops in on a termite mating ritual (while his guides snack on the subjects), visits freelance baboon goatherds, and swims with a mixed family of whales and dolphins. Along the way, Ward shows that the social impulses we’ve long thought separated humans from other animals might actually be our strongest connection to them. Insightful, engaging, and often hilarious, The Social Lives of Animals demonstrates that you can learn more about animals by studying how they work together than by how they compete.

Download or read book Antarctic Ecosystems written by Alex D. Rogers and published by John Wiley & Sons. This book was released on 2012-02-28 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.

Download or read book Krill written by Jonah Young and published by Ice Press. This book was released on 2015-01-06 with total page 79 pages. Available in PDF, EPUB and Kindle. 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.

NYPL best books of 2022 California Eureka Silver Honoree award 2022 "To my delight, your average krill is a far stranger story of metamorphosis than anything our butterflies can come up with." - Elizabeth Bird, A Fuse 8 Production A fun exploration of a tiny animal at the base of the ocean food chain Just 2 inches long full-grown, this little guy is the foundation of the Southern Ocean food chain... “Hi. What are you? You appear to be an egg. You are an egg sinking. For many days, you sink. You sink a mile down, and you keep sinking down… down… until…” The unidentified narrator follows one krill among billions as it pursues its brief existence, eating and eating while metamorphosing from one thing into another and trying to avoid being eaten. Questions and advice are hurled at the krill on every page, but the krill never responds—because, after all, krill can’t talk, and this is nonfiction. Krill are the largest animals able to catch and eat phytoplankton, and they in turn are eaten by the largest animals ever to live on earth—blue whales—as well as by seals, penguins, and a host of others. In other words, krill are really good at eating, and they make really good eating. And that makes them the most important animals in the high-latitude oceans. As in The Whale Fall Café, Dan Tavis’s illustrations combine scientific accuracy with Nemo liveliness and humor. Our star krill is so good at gobbling up phytoplankton that he turns green, so we can pick him out from the crowd racing to escape a penguin’s beak or a blue whale’s gaping maw. The book has been reviewed and endorsed by global krill expert Dr. Stephen Nichol, and the manuscript earned an honorable mention in Minnesota’s McKnight Artist Fellowships for Writers. Helpful backmatter is included. The Good Eating manuscript won an honorable mention in Minnesota’s McKnight Artist Fellowships for Writers.

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.
