Download or read book Evolution De La Biosphere Et E written by Francis Lethiers and published by Routledge. This book was released on 2021-09-09 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of the living world has not been straightforward process over geological time. On the contrary, it shows episodes of crises separating phases of evolving radiation. This work, presenting an assessment of the paleontological discoveries of the last fifteen years, could be summed up by the formula "the evolution of life on our planet or biodiversity". This book, which combines clarity of presentation with scientific rigor, will be of interest to biologists and geologists as well as teachers, students and all those wishing to extend their knowledge on the subject.

Download or read book Physiological Ecology of Pacific Salmon written by Cornelis Groot and published by UBC Press. This book was released on 2010-10-01 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.

This book was released on 2012-12-06 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the end of the last century and the beginning of this century, the prob lems of immunity in lower vertebrates and the influence of environmental temperature attracted attention for the first time (ERNST, 1890; WIDAL and SICARD, 1897; METCHNIKOFF, 1901). However, relatively little work has been done on this subject until recently. The early investigators were chiefly in terested in the immuno-pathological problems. They immunized various species of lower vertebrates essentially with bacterial vaccines; agglutinating, neutralizing and protective antibodies were detected in their blood. The in fluence of environmental temperature on the immune response was investigated, since this subject represented great economical and theoretical importance. Epizootic diseases were observed to occur in relation to the cold season of the year, when the decrease or spontaneous increase of water temperature occurred (SCHAPERCLAUS, 1965; BESSE et al. , 1965; KLONTZ et al. , 1965 WOOD,1966). The immunological deficiency of fish, caused by their natural or experimental stay in cold water, is now evident for both humoral and cellular immunity. In this review we will focus on two points: We shall attempt (1) to explain the mechanism by which the environmental temperature influences the immune resistance of fish to pathogens, (2) to determine the chronological location of this temperature-sensitive stage in the process of antibody formation, and to make some approaches to the general antibody formation mechanism.
Download or read book Evolutionary Genetics written by Charles W. Fox and published by Oxford University Press. This book was released on 2006-04-27 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles Fox and Jason Wolf have brought together leading researchers to produce a cutting-edge primer introducing readers to the major concepts in modern evolutionary genetics. This book spans the continuum of scale, from studies of DNA sequence evolution through proteins and development to multivariate phenotypic evolution, and the continuum of time, from ancient events that lead to current species diversity to the rapid evolution seen over relatively short time scales in experimental evolution studies. Chapters are accessible to an audience lacking extensive background in evolutionaryy genetics but also current and in-depth enough to be of value to established researchers in evolution biology.

Available in PDF, EPUB and Kindle. Book excerpt: The book is a multi-authored book of 18 chapters comprising the state of the art work of all relevant topics on modern fish histology from 28 authors from ten countries. The topics include Introduction to Histological Techniques, Integument, Fish Skeletal Tissues, Muscular System, Structure and Function of Electric Organs, Digestive System, Glands of the Digestive Tract, Swim Bladder, Kidney, Ovaries and Eggs, Egg Envelopes, Testis Structure, Spermatogenesis, and Spermatozoa in Teleost Fishes, Cardiovascular System and Blood, Immune System of Fish, Gills: Respiration and Ionic-Osmoregulation, Sensory Organs, Morphology and Ecomorphology of the Fish Brain, and Endocrine System. Structural and functional aspects are treated and in a comparative way fish diversity at various taxonomic levels is integrated.
