Physiology of the Cladocera
Author: Nikolai N. SmirnovPublisher: Academic Press
ISBN: 0128052813
Category : Science
Languages : en
Pages : 420
Book Description
Physiology of the Cladocera, Second Edition, is a much-needed summary of foundational information on these increasingly important model organisms. This unique and valuable review is based on the world’s literature, including Russian research not previously widely available, and offers systematically arranged data on the physiology of Cladocera, assisting with explanation of their life and distribution. It features the addition of new sections and a vast amount of new information, such as the latest data on feeding, nutrition, pathological physiology, chemical composition, neurosecretion, and behavior, as well as hormonal regulation, antioxidants, and the biochemical background of effects of natural and anthropogenic factors. Additional expertly updated contributions in genetics and cytology, and a new chapter in embryology, round out the physiological chapters, and provide comprehensive insight into the state of knowledge of Cladocera and their underlying mechanisms. Cladocera crustaceans have become globally studied for many purposes, including genetic, molecular, ecological, environmental, water quality, systematics, and evolutionary biology research. Since the genome of Daphnia was sequenced and published, that system has gained much wider exposure, also leading to a rapidly growing awareness of the importance of understanding physiological processes as they relate to evolutionary and ecological genomics as well as ecogenomic toxicology. However, the physiological background on Cladocera has been fragmentary (including on the other 700 known species besides Daphnia), despite the extensive literature on species identification and morphology. This work addresses this issue by collecting and synthesizing from the literature the state of knowledge of cladoceran physiology, including discussion on both adequately and inadequately investigated fields, and thus directions of future research. Summarizes fundamental information obtained in recent years, including on steroids, antioxidants, hormones, nanoparticles, and impact of wastewater of pharmaceutical industries Provides the foundational information needed for scientists and practitioners from a variety of fields, including conservation and evolutionary biology, genomics, ecology, ecotoxicology, comparative physiology, limnology, zoology–carcinology, and water quality assessment Features coverage of both Daphniids and representatives of other families, with attention drawn to little-studied aspects of their physiology, especially of those living in the litt oral zone Includes guidance to the literature on cladoceran physiology in four languages Discusses advantages and shortcomings of Cladocera as experimental animals and indicators of water quality
Diapause in the Crustacea
Author: Victor R. AlekseevPublisher: Springer
ISBN:
Category : Nature
Languages : en
Pages : 260
Book Description
Focuses on the ability crustaceans share with a wide range of invertebrates, to lay eggs that can survive for years without any apparent metabolism in a dry condition, then rapidly develop when water finally comes, and lay another generation of resting eggs. The 26 papers cover the evolutionary aspects, the physiology, induction and termination, the nature of resting stages and their role in the population dynamics of marine and freshwater crustaceans, and crustacean life histories. Specific topics include micro- and macro-evolutionary patterns and processes influencing the distribution of crustacean diapause, the variation in torpidity of diapause in freshwater cyclopoid copepods, the significance of photoperiodism and diapause control in the multicycle Crustacean Daphnia pulex Leydig, the role of parthenogenetic natality and emergence from diapausing eggs in the dynamics of some rotifer populations, and the role of food availability in the variable life history of a cyclopoid copepod.

Copepods in Aquaculture
Author: Cheng-Sheng LeePublisher: John Wiley & Sons
ISBN: 0470276304
Category : Technology & Engineering
Languages : en
Pages : 286
Book Description
The importance of copepods in aquaculture has long been recognized, especially in the larval rearing of many marine fishes. This timely publication provides a single source of information on copepod biology, culture methods and practical use in marine finfish hatcheries. Originating out of a workshop held on copepods by the Oceanic Institute in Hawaii, this proceedings includes review articles and papers presented by leading international experts in copepod biology and aquaculture. It is a seminal work that integrates the most up-to-date information on selecting copepod species, effects of algal species on reproduction, ways to increase production, the nutritional value of copepods, behavioral characteristics of copepods, potential use of copepod nauplii and eggs, and their application to larval rearing of various marine finfish species.

Arctic Animal Ecology
Author: Hermann RemmertPublisher: Springer Science & Business Media
ISBN: 364267710X
Category : Science
Languages : en
Pages : 258
Book Description
A large number of comprehensive publications has been devoted to the Antarctic, to its plant and animal life. It is therefore relatively easy to familiarize oneself with the current state of Antarctic research. Nothing comparable is available for the Arctic. The heterogeneity and richness of the northern polar regions seem to have discouraged any attempt at a synthethic approach. This book has evolved from an attempt to summarize the results of 15 years of ecological and physiological research work in the Arctic - mostly on Spitsbergen. The necessity of comparing our results and the ecological conditions of Spitsbergen with other arctic regions grew into a full-sized book on arctic animal ecology. It is not meant as an exhaustive survey ofthe relevant literature. Instead I have tried to show how closely the various fields of research are interwoven, how many questions can be solved if only notice is taken of fellow scientists and their results, and how much arctic animals have in common. This book would not have been possible without the helpfulness of many colleagues. Above all I should like to mention Professor Ronning and Professor Solem of Trondheim University (Norway), Professor Arnthor Gardasson of Reykjavik University (Iceland), Dr. NettIeship, Dr. Oliver and Dr. Ryder of Canada and Professor West of Fairbanks University (Alaska, USA).
Manual on the Production and Use of Live Food for Aquaculture
Author: Patrick LavensPublisher: Food & Agriculture Organization of the UN (FAO)
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 320
Book Description
The cultivation of fish and shellfish larvae under controlled hatchery conditions requires not only the development of specific culture techniques, but in most cases also the production and use of live food organisms as feed for the developing larvae. The present manual describes the major production techniques currently employed for the cultivation of the major types of live food commonly used in larviculture, as well as their application potential in terms of their nutritional and physical properties and feeding methods. The manual is divided into different sections according to the major groups of live food organisms used in aquaculture, namely micro-algae, rotifers, Artemia, natural zooplankton, and copepods, nematodes and trochophores.
Principles of Ecology

Languages : en
Pages : 384
Book Description
As Ecology teachers ourselves we have become increasingly aware of the lack of a single comprehensive textbook of Ecvlogy which we can recommend unreservedly to our students. While general, review texts are readily available in other fields, recent publications in Ecology have tended for the most part to be small, specialised works on single aspects of the subject. Such general texts as are available are often rather too detailed and, in addition, tend to be somewhat biased towards one aspect of the discipline or another and are thus not truly balanced syntheses of current knowledge. Ecology is, in addition, a rapidly developing subject: new information is being gathered all the time on a variety of key questions; new approaches and techniques open up whole new areas of research and establish new principles. Already things have changed radically since the early '70s and we feel there is a need for an up to date student text that will include some of this newer material. We have tried, therefore, to create a text that will review all the major principles and tenets within the whole field of Ecology, presenting the generally accepted theories and fundamentals and reviewing carefully the evidence on which such principles have been founded. While recent developments in ecological thought are emphasised, we hope that these will not dominate the material to the extent where the older-established principles are ignored or overlooked.
