Download or read book Life in the Open Ocean written by Joseph J. Torres and published by John Wiley & Sons. This book was released on 2022-01-31 with total page 1044 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life in the Open Ocean Life in the Open Ocean: The Biology of Pelagic Species provides in-depth coverage of the different marine animal groups that form the communities inhabiting the ocean’s pelagic realm. This comprehensive resource explores the physical environment, foraging strategies, energetics, locomotion, sensory mechanisms, global and vertical distributions, special adaptations, and other characteristics of a wide array of marine taxa. Bringing together the most recent information available in a single volume, authors Joseph J. Torres and Thomas G. Bailey cover the Cnidaria (stinging jellies), the ctenophores (comb jellies), pelagic nemerteans, pelagic annelids, crustaceans, cephalopods and pelagic gastropods, invertebrate chordates, as well as micronektonic and larger fishes such as sharks, tunas, mackerels, and mahi-mahi. Detailed chapters on each pelagic group describe internal and external anatomy, classification and history, feeding and digestion, bioluminescent systems and their function, reproduction and development, respiration, excretion, nervous systems, and more. The first book of its kind to address all of the major animal groups comprising both the swimmers and drifters of the open sea, this important resource: Explains how different animals have adapted to live in the open-ocean environment Covers all sensory mechanisms of animals living in the pelagic habitat, including photoreception, mechanoreception, and chemoreception Treats the diverse micronekton assemblage as a community Includes a thorough introduction to the physical oceanography and properties of water in the pelagic realm Life in the Open Ocean: The Biology of Pelagic Species is an excellent senior-level undergraduate and graduate textbook for courses in biology and biological oceanography, and a valuable reference for all those with interest in open-ocean biology.
Download or read book Fish Karyotypes written by Ryoichi Arai and published by Springer Science & Business Media. This book was released on 2011-06-26 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the largest group of extant vertebrates, fish offer an almost limitless number of striking examples of evolutionary adaptation to environmental and biotic selection pressure. The most diverse of all vertebrate groups, the higher taxa of fish traditionally have been classified by morphology and paleontology, with a much smaller input of cytogenetic information. DNA sequence data are exerting an increasingly strong influence on modern fish systematics, challenging the classification of numerous higher taxa ranging from genera to orders. The most fruitful approach, however, involves synthetic analyses of morphology, molecular phylogenetics, comparative karyology, and genome size. Karyotypes of more than 3400 species/subspecies are arranged here by fish systematics and include a list of genome size, sex chromosomes, B chromosomes, polyploidy, and locality of material fish, among others. This volume enables both beginners and advanced researchers to survey the existing literature and facilitates the implementation of an integrative approach to fish systematics. The first book on fish chromosomes in nearly 15 years, it is also the most comprehensive.

This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of the hazards resulting from the accidental or deli berate contamination of terrestrial and aquatic environments is in most countries still lirnited to the detection and quantification of the suspected pollutants by chemical analyses. Such an approach is unfortunately hampered by the following constraints : the costs as weil as the technical difficulties of analyzing every individual chemical which may be present in the sampies, and the difficulty of assessing the hazards and risks of environmental contaminations from a set of chemical data. During the last decades the scientific and regulatory community has gradually realized that biological methodologies have to be taken into consideration for an ecologically meaningful assessment of the toxicological hazards of contaminants. Effect evaluations obtained with biological techniques indeed integrate the impact of all the contaminants to which living biota are exposed. Bioassays with selected test species representative for the biological commumtles of the environments under consideration, are now applied more or less regularly to determine toxic and genotoxic effects. Taking into account the species specific and chemical specific character of toxicity to biota, the necessity of a «battery of tests» approach with species of different trophic levels is currently also generally accepted and implemented. It is dear that a balanced partnership between chemical, biological, toxicological and microbiological analyses is always the best strategy for generating the broadest information base on environmental hazards.

Download or read book Theories of Population Variation in Genes and Genomes written by Freddy Bugge Christiansen and published by Princeton University Press. This book was released on 2014-11-23 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides an authoritative introduction to both classical and coalescent approaches to population genetics. Written for graduate students and advanced undergraduates by one of the world's leading authorities in the field, the book focuses on the theoretical background of population genetics, while emphasizing the close interplay between theory and empiricism. Traditional topics such as genetic and phenotypic variation, mutation, migration, and linkage are covered and advanced by contemporary coalescent theory, which describes the genealogy of genes in a population, ultimately connecting them to a single common ancestor. Effects of selection, particularly genomic effects, are discussed with reference to molecular genetic variation. The book is designed for students of population genetics, bioinformatics, evolutionary biology, molecular evolution, and theoretical biology--as well as biologists, molecular biologists, breeders, biomathematicians, and biostatisticians. Contains up-to-date treatment of key areas in classical and modern theoretical population genetics Provides in-depth coverage of coalescent theory Discusses genomic effects of selection Gives examples from empirical population genetics Incorporates figures, diagrams, and boxed features throughout Includes end-of-chapter exercises Speaks to a wide range of students in biology, bioinformatics, and biostatistics
Download or read book Practical Studies of Animal Development written by F. S. Billett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is twofold: it is meant to serve both as a practical manual for the study of animal development and as a general introduction to the subject. Central to our en deavour is the belief that developmental biology is best taught and learnt at the laboratory bench, with specimens which are either alive and can be seen to develop or with fresh material derived directly from the egg (as in birds) or mother (as in mammals). Once the dynamic nature of development is appreci ated and the overall structure of the developing organism discerned the more conventional study of sections and whole mounts is more likely to become a delight rather than a diffi cult, and often meaningless, chore. We have laid considerable stress on the early development of animal embryos and the ways in which they can be obtained from a relatively few, but reliable, sources. In addition, emphasis has been placed on fairly simple experiments which make use of the embryos and larvae chosen for the purpose of illustrating develop ment. Embryology ceased to be a descriptive science at the beginning of this century and any practical course, at what ever level, should attempt to reflect this change. It is true that the analysis of development, particularly the genesis of chor date structure, owed much to the invention of the microtome.
