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.

This book was released on 2013-11-11 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stone carving from the 14th century B.C. records that the Egyptian pharaoh Akhenaten (born Amenhoteph IV) and his wife, Nefertiti, recognized the importance of sunlight to life. In fact, Akhenaten initiated a monotheistic religion, with Aton, the sun, as God. One of his daughters be came the wife of King Tut Ankamon, the spelling of whose name indicates a return to the old religion and an eclipse of interest in photobiology among the pharaohs. A renewal of interest in photobiology in modern times was climaxed in 1928 by the establishment of an international organization for photobiology under the title Comite International de la Lumiere (C.I.L.). Its present title, Comite International de Photobiologie (C.I.P.), was adopted at a meeting in Paris in 1951. The first of a series of international congresses on photobiology was held in 1954 and probably represents the beginning of modern day photobiology. Medical men were prominent in the activities of the old C.I.L., for the importance of natural sunlight in human health and disease was obvious though not well understood. The bringing together of physicians with physicists, chemists, and biologists from the pure and applied branches of their subjects was the aim of the older C.I.L. and continues to the present day through the C.I.P.
Download or read book Sense Organs Integration and Behavior written by Talbot Waterman and published by Elsevier. This book was released on 1961-01-01 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Crustacea, Volume II: Sense Organs, Integration, and Behavior focuses on the three components of self-regulation for crustaceans and examines the behavior that emerges therefrom. This book provides the physiology of the class Crustacea from a comparative point of view. Organized into chapters, this volume starts with an overview of the sensitivity to electromagnetic energy at wavelengths extending from the ultraviolet to the infrared, which is an important adaptive function in crustaceans. This text then explores the innervation of crustacean sensory hairs and describes the sensitivity among crustaceans to external changes in mechanical force by direct contact with solids or by fluid movement. Other chapters consider the two types of pigmentary effectors in crustaceans, namely, the chromatophores and the pigments of the compound eye. The final chapter deals with the four major categories in developing a comparative physiology. Physiologists, biochemists, and researchers will find this book useful.
