Download or read book Oceanic Migration written by Charles E.M. Pearce and published by Springer Science & Business Media. This book was released on 2010-06-17 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanic Migration studies the prehistoric peopling of the Pacific. It uses science and mathematics to expand the research base of Pacific prehistory and casts new light on this final human expansion. It explores the fundamental roles of oceanography and of global climate change in determining the paths, sequence, timing and range of Spice Island-based maritime migrations ranging across a quarter of the globe. The book is of interest to Pacific prehistorians, oceanographers and American anthropologists concerned with the diffusionist debate. For oceanographers it presents the new idea of the role of the West Pacific Warm Pool and of three of its four major currents in determining the evolution of voyaging in two oceans. For diffusionists it provides new chronological and technological contexts in which the issue of diffusionism needs to be reconsidered. For prehistorians it creates a paradigmatic shift by establishing a new time depth and mechanism for Polynesian exploration, offers a new view of voyaging and exploration strategies and of economic imperatives and adds a new dimension to the debate on Polynesian origins.
Download or read book Diel Vertical Migration of Zooplankton in Lakes and Oceans written by Joop Ringelberg and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10–40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of “Krill” may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.
Download or read book Spawning Migration of the European Eel written by Guido van den Thillart and published by Springer Science & Business Media. This book was released on 2008-12-18 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater eels are almost infinitely improbable creatures. They spawn and die in the middle of the ocean, often associated with undersea mountains. Their tra- parent, leaf-like larvae move with ocean currents for months or years until they approach the mouths of freshwater rivers. Then they undergo a dramatic transf- mation in morphology, physiology and behavior. They move from their planktonic oceanic environment, migrate upstream and live for several years as apex fre- water predators. Then, almost impossibly, as they become sexually mature, they reverse their migration downstream to the ocean and back to spawning grounds to complete their life cycle. The dramatic changes in their life cycles are incredible. The efforts to unravel the details of their life history have been truly daunting. Much of the past research was the work of dedicated individuals who devoted their lifetime research to these fishes. Freshwater eels merit a separate chapter in almost any textbook dealing with ichthyology, marine biology or animal migration. We know a great deal about some aspects of the biology of freshwater eels. However, our understanding of their bi- ogy still resembles a work of art as much as a work of science. To some it appears like the sweeping brush strokes of a Japanese Zen landscape, to others it resembles the work of a French impressionist, and to still others it appears as magic realism.
Download or read book Animal Migration Orientation and Navigation written by Gauthreaux and published by Elsevier. This book was released on 2012-12-02 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Migration, Orientation, and Navigation presents the various aspects of animal migration, including the evolution of migration, climatic and meteorological influences, and bioenergetics. This book discusses the physiological control, sensory systems, orientation and navigation, and biological clocks and phenology aspects of animal migration. Organized into five chapters, this book begins with an overview of the migration strategies of animals in the context of a space continuum. This text then explains the influence of short- and long-term climatic cycles on the spectrum of migratory patterns in nature. Other chapters consider the energetic requirements of different migration strategies and the energy stores of the migrants. This book discusses as well the physiological basis of animal migration, with emphasis on endocrinal findings on the timing and energetic aspects of different migration strategies. The final chapter deals with the mechanisms used in direction finding by migrating animals. This book is a valuable resource for biologists and ecologists.
