Book Synopsis Southern Ocean Ecology by : Sayed Z. El-Sayed
Download or read book Southern Ocean Ecology written by Sayed Z. El-Sayed and published by Cambridge University Press. This book was released on 1994-02-24 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: BIOMASS (Biological Investigations of Marine Antarctic Systems and Stocks) was a unique, large-scale, long-term, international research programme established in 1977 to investigate the ecology of the Southern Ocean. Its main aim was to gain a greater understanding of the biological systems and stocks in the marine Antarctic environment, thereby providing a sound basis for the future management of the living resources within this immense ocean. The programme was drawn to a close in 1991 and its completion marked by a colloquium which brought together key researchers to summarise and review the results obtained. This volume, arising from that colloquium, provides a succinct, state-of-the-art account of the ecology of the Southern Ocean and serves as a comprehensive record of this unique and successful international project.

Book Synopsis Life in the Open Ocean by : Joseph J. Torres
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.
Book Synopsis Antarctic Ecosystems by : Alex D. Rogers
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 Jellyfish Blooms written by Kylie A. Pitt and published by Springer Science & Business Media. This book was released on 2013-11-04 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jellyfish are one of the most conspicuous animals in our oceans and are renowned for their propensity to form spectacular blooms. The unique features of the biology and ecology of jellyfish that enable them to bloom also make them successful invasive species and, in a few places around the world, jellyfish have become problematic. As man increasingly populates the world’s coastlines, interactions between humans and jellyfish are rising, often to the detriment of coastal-based industries such as tourism, fishing and power generation. However we must not lose sight of the fact that jellyfish have been forming blooms in the oceans for at least 500 million years, and are an essential component of normal, healthy ocean ecosystems. Here many of the world’s leading jellyfish experts explore the science behind jellyfish blooms. We examine the unique features of jellyfish biology and ecology that cause populations to ‘bloom and bust’, and, using case studies, we show why jellyfish are important to coastal and ocean ecosystem function. We outline strategies coastal managers can use to mitigate the effects of blooms on coastal industries thereby enabling humans to coexist with these fascinating creatures. Finally we highlight how jellyfish benefit society; providing us with food and one of the most biomedically-important compounds discovered in the 20th century.

Book Synopsis Reproduction and Development in Echinodermata and Prochordata by : T. J. Pandian
Download or read book Reproduction and Development in Echinodermata and Prochordata written by T. J. Pandian and published by CRC Press. This book was released on 2018-04-17 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Echinoderms and prochordates occupy a key position in vertebrate evolution. The genomes of sea urchin share 70% homology with humans. Researches on cell cycle in sea urchin and phagocytosis in asteroids have fetched Nobel Prizes. In this context, this book assumes immense importance. Echinoderms are unique, as their symmetry is bilateral in larvae but pentamerous radial in adults. The latter has eliminated the development of an anterior head and bilateral appendages. Further, the obligate need to face the substratum for locomotion and acquisition of food has eliminated their planktonic and nektonic existence. Egg size, a decisive factor in recruitment, increases with decreasing depths up to 2,000-5,000 m in lecithotrophic asteroids and ophiuroids but remains constant in their planktotrophics. Smaller ( 110 mm) asteroids generate planktotrophic eggs only. Publications on sex ratio of echinoderms indicate the genetic determination of sex at fertilization but those on hybridization, karyotype and ploidy induction do not provide evidence for heterogametism. But the herbivorous echinoids and larvacea with their gonads harboring both germ cells and Nutritive Phagocytes (NPs) have economized the transportation and hormonal costs on gonadal function. Despite the amazing potential just 2 and 3% of echinoderms undergo clonal reproduction and regeneration, respectively. Fission is triggered, when adequate reserve nutrients are accumulated. It is the most prevalent mode of clonal reproduction in holothuroids, asteroids and ophiuroids. However, budding is a more prevalent mode of clonal reproduction in colonial hemichordates and urochordates. In echinoderms, fission and budding eliminate each other. Similarly, autoregulation of early development eliminates clonal reproduction in echinoids and solitary urochordates. In pterobranchs, thaliaceans and ascidians, the repeated and rapid budding leads to colonial formation. Coloniality imposes reductions in species number and body size, generation time and life span, gonad number and fecundity as well as switching from gonochorism to simultaneous hermaphorditism and oviparity to ovoviviparity/viviparity.
