Book Synopsis Water Pollution and Fish Physiology by : Alan G. Heath
Download or read book Water Pollution and Fish Physiology written by Alan G. Heath and published by CRC Press. This book was released on 2018-02-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise synthesis of how toxic chemical pollutants affect physiological processes in teleost fish. This Second Edition of the well-received Water Pollution and Fish Physiology has been completely updated, and chapters have been added on immunology and acid toxicity. The emphasis, as in the first edition, is on understanding mechanisms of sublethal effects on fish and their responses to these environmental stressors. The first chapter covers the basic principles involved in understanding how fish respond, in general, to environmental alterations. Each subsequent chapter is devoted to a particular organ system or physiological function and begins with a short overview of normal physiology of that system/function. This is followed by a review of how various toxic chemicals may alter normal conditions in fish. Chapters covering environmental hypoxia, behavior, cellular enzymes, and acid toxicity are also included. The book closes with a discussion on the practical application of physiological and biochemical measurements of fish in water pollution control in research and regulatory settings.
Book Synopsis The Effects of Environmental Stressors on Cardiac Gene Expression and Contractility in Rainbow Trout (Oncorhynchus Mykiss) by : Tracey S. Momoda
Download or read book The Effects of Environmental Stressors on Cardiac Gene Expression and Contractility in Rainbow Trout (Oncorhynchus Mykiss) written by Tracey S. Momoda and published by . This book was released on 2014 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainbow trout (Oncorhynchus mykiss) experience a variety of stressors in their natural environment as well as in aquaculture that can have negative effects on their physiology. The effects of physiological stress and endocrine disruption have been well described in fish. However, there is a scarcity of information on the effects of such stressors on the heart in fish. We examined gene expression in the rainbow trout heart in response to 17[alpha]-ethinylestradiol (EE), the active ingredient in some oral contraceptives, as well as physiological stress. We also assessed contractile function, as a measure of cardiac performance, under conditions of increasing performance demands in sexually immature rainbow trout. In chapter 2, using qRT-PCR, we observed increased vitellogenin (vtg1) in the ventricle, along with, hepatic estrogen receptor (ER[alpha]) and vtg1 mRNA increased with EE exposure, confirming endocrine disruption in both tissues. Stress increased corticotropin-releasing factor receptor 1 (CRF-R1) and JunB in response to stress while nuclear protein 1 (nupr1) and glucocorticoid receptor (GCR2) expression increased only in the population with higher cortisol levels (>100 ng/ml) in response to stress. Interestingly, EE exposure did not affect stress induced gene expression and stress did not have an effect on EE induced gene expression in the heart of rainbow trout. This research highlights the fact that these stressors have the potential to have physiological impacts beyond the target tissues classically thought of for stress (i.e. HPI/A axis) or exposure to estrogenic compounds (i.e. HPG axis). In chapter 3, contractile force production was measured from ventricle strips exposed to increasing concentrations of Ca2 or epinephrine to simulate conditions of increasing performance. Also, to determine the effects of physiological stress, ventricle strips were pre-treated with 100 ng/L cortisol prior to increasing Ca2 or epinephrine. Ventricle strips from males had a greater contractile force production to increasing Ca2+ or epinephrine compared to females, at concentrations greater than 3.5 mM Ca2+ or 1 [micro]M epinephrine. Exposure to cortisol did not have a direct effect on contractility, nor did it have an effect the contractile response to increasing exogenous Ca2+ in either sex. Interestingly, force production did not vary by sex in the cortisol pre-treated exposed to epinephrine, suggesting a sex-dependent response. My findings suggest that there are sex differences in the contractile function in rainbow trout and that these may be modified under conditions related to physiological stress. The rainbow trout is a genetically diverse species found across a variety of habitats. Our results highlight the variation in responses in in contractile function and gene expression in the heart by the different sexes, as well as variation within and among populations that allow rainbow trout to adapt and perform in the presence of stressors in the environment.

Book Synopsis Encyclopedia of Fish Physiology by :
Download or read book Encyclopedia of Fish Physiology written by and published by Academic Press. This book was released on 2011-06-01 with total page 2275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish form an extremely diverse group of vertebrates. At a conservative estimate at least 40% of the world's vertebrates are fish. On the one hand they are united by their adaptations to an aquatic environment and on the other they show a variety of adaptations to differing environmental conditions - often to extremes of temperature, salinity, oxygen level and water chemistry. They exhibit an array of behavioural and reproductive systems. Interesting in their own right, this suite of adaptive physiologies provides many model systems for both comparative vertebrate and human physiologists. This four volume encyclopedia covers the diversity of fish physiology in over 300 articles and provides entry level information for students and summary overviews for researchers alike. Broadly organised into four themes, articles cover Functional, Thematic, and Phylogenetic Physiology, and Fish Genomics. Functional articles address the traditional aspects of fish physiology that are common to all areas of vertebrate physiology including: Reproduction, Respiration, Neural (Sensory, Central, Effector), Endocrinology, Renal, Cardiovascular, Acid-base Balance, Osmoregulation, Ionoregulation, Digestion, Metabolism, Locomotion, and so on. Thematic Physiology articles are carefully selected and fewer in number. They provide a level of integration that goes beyond the coverage in the Functional Physiology topics and include discussions of Toxicology, Air-breathing, Migrations, Temperature, Endothermy, etc. Phylogenetic Physiology articles bring together information that bridges the physiology of certain groupings of fishes where the knowledge base has a sufficient depth and breadth and include articles on Ancient Fishes, Tunas, Sharks, etc. Genomics articles describe the underlying genetic component of fish physiology and high light their suitability and use as model organisms for the study of disease, stress and physiological adaptations and reactions to external conditions. Winner of a 2011 PROSE Award Honorable Mention for Multivolume Science Reference from the Association of American Publishers The definitive encyclopedia for the field of fish physiology Three volumes which comprehensively cover the entire field in over 300 entries written by experts Detailed coverage of basic functional physiology of fishes, physiological themes in fish biology and comparative physiology amongst taxonomic Groups Describes the genomic bases of fish physiology and biology and the use of fish as model organisms in human physiological research Includes a glossary of terms

This book was released on 2009-07-24 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hopefully, this book will be taken off of the shelf frequently to be studied carefully over many years. More than 40 researchers were involved in this project, which examines respiration, circulation, and metabolism from ?sh to the land vertebrates, including human beings. A breathable and stable atmosphere ?rst appeared about 500 million years ago. Oxygen levels are not stable in aquatic environments and exclusively water-breathing ?sh must still cope with the ever-changing levels of O 2 and with large temperature changes. This is re?ected in their sophisticated count- current systems, with high O extraction and internal and external O receptors. 2 2 The conquest for the terrestrial environment took place in the late Devonian period (355–359 million years ago), and recent discoveries portray the gradual transitional evolution of land vertebrates.

Recently, physiology has expanded into related ?elds such as biochemistry, molecular biology, morphology and anatomy. In the light of the work in these ?elds, the introduction of DNA-based cladograms, which can be used to evaluate the likelihood of land vertebrates and lung?sh as a sister group, could explain why their cardio-respiratory control systems are similar. The diffusing capacity of a duck lung is 40 times higher than that of a toad or lung?sh. Certainly, some animals have evolved to rich high-performance levels.

Book Synopsis Fish Physiology: Hypoxia by : Jeffrey G. Richards
Download or read book Fish Physiology: Hypoxia written by Jeffrey G. Richards and published by Academic Press. This book was released on 2009-03-10 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periods of environmental hypoxia (Low Oxygen Availability) are extremely common in aquatic systems due to both natural causes such as diurnal oscillations in algal respiration, seasonal flooding, stratification, under ice cover in lakes, and isolation of densely vegetated water bodies, as well as more recent anthropogenic causes (e.g. eutrophication). In view of this, it is perhaps not surprising that among all vertebrates, fish boast the largest number of hypoxia tolerant species; hypoxia has clearly played an important role in shaping the evolution of many unique adaptive strategies. These unique adaptive strategies either allow fish to maintain function at low oxygen levels, thus extending hypoxia tolerance limits, or permit them to defend against the metabolic consequences of oxygen levels that fall below a threshold where metabolic functions cannot be maintained. The aim of this volume is two-fold. First, this book will review and synthesize the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure and place them within an environmental and ecological context. Second, through the development of a synthesis chapter this book will serve as the cornerstone for directing future research into the effects of hypoxia exposures on fish physiology and biochemistry. - The only single volume available to provide an in-depth discussion of the adaptations and responses of fish to environmental hypoxia - Reviews and synthesizes the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure - Includes discussion of the evolutionary and ecological consequences of hypoxia exposure in fish

Book Synopsis Neuropeptide GPCRs in neuroendocrinology by : Jae Young Seong
Download or read book Neuropeptide GPCRs in neuroendocrinology written by Jae Young Seong and published by Frontiers E-books. This book was released on 2014-11-07 with total page 826 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human genome encompasses ˜ 860 G protein-coupled receptors (GPCRs) including 374 non-chemosensory GPCRs. Half of these latter GPCRs recognize (neuro)peptides as natural ligands. GPCRs thus play a pivotal role in neuroendocrine communication. In particular, GPCRs are involved in the neuroendocrine control of feeding behavior, reproduction, growth, hydromineral homeostasis and stress response. GPCRs are also major drug targets and hence possess a strong potential for the development of innovative pharmaceuticals. The aim of this Research Topic was to assemble a series of review articles and original research papers on neuropeptide GPCRs and their ligands that would illustrate the different facets of the studies currently conducted in this domain.

Download or read book Fish Ecophysiology written by J.C. Rankin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes. ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts. in the deep sea. in the cold antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specialisations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas, air-breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious. delicious and diverse food. Rational exploi management of our global stocks of fishes must rely upon a detailed tation and and precise insight of their biology. The Chapman [.,. Hall Fish and Fisheries series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of IIsh and t1sheries.
