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.

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 384 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 Fish Osmoregulation by : Bernardo Baldisserotto
Download or read book Fish Osmoregulation written by Bernardo Baldisserotto and published by CRC Press. This book was released on 2019-05-20 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish lives in environments with a wide variety of chemical characteristics (fresh, brackish and seawater, acidic, alkaline, soft and hard waters). From an osmoregulatory point of view, fish have developed several mechanisms to live in these different environments. Fish osmoregulation has always attracted considerable attention and in the last years several studies have increased our knowledge of this physiological process. In this book several specialists have analyzed and reviewed the new data published regarding fish osmoregulation. The chapters present an integrative synthesis of the different aspects of this field focusing on osmoregulation in specific environments or situations, function of osmoregulatory organs, general mechanisms and endocrine control. In addition, interactions of osmoregulatory mechanisms with the immune system, diet and metabolism were also reviewed. New emerging techniques to study osmoregulation has also been analysed.

Book Synopsis Physiological Ecology of Pacific Salmon by : Cornelis Groot
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.

Book Synopsis Multiple Stresses in Ecosystems by : Jr. Cech
Download or read book Multiple Stresses in Ecosystems written by Jr. Cech and published by Routledge. This book was released on 2017-11-01 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is the evaluation of toxic effects within the environment, typically within one specific ecosystem, like a forest, stream, or lake. For years now, ecotoxicological studies have tended to focus on one toxicant at a time. But that isn't how an ecosystem encounters toxicants (or stresses): there may be several elements at work in the air, several more in the water, and still more already within the soil of any given ecosystem, and all have some level of toxic influence on that ecosystem. Multiple Stresses in Ecosystems presents the state-of-the-art in determining the effects of these multiple impacts upon ecosystems. Resulting from a vanguard conference originally held in 1993 at UC Davis, this new work is divided into three sections that present methodolgies for assessing the health of an ecosystem; the effects of multiple toxicological impacts upon an ecosystem, and which tools are worth using to assess these dangers. Environmental scientists, chemists, toxicologists, risk analysts, and probably the entire membership of SETAC will find need for this book, as will wetlands scientists, ecologists, and research biologists.
