Available in PDF, EPUB and Kindle. Book excerpt: Despite the threat of climate change, the physiological mechanisms by which temperature drives the distribution of species are unclear. Here we used chronic temperature exposures to determine that the upper limit for positive growth in the eastern brook trout (Salvelinus fontinalis) is 23.4 °C. Additionally, brook trout exposed to daily temperature oscillations of 8 °C, around a mean of 21 °C, exhibited growth rates that were 43 and 35% lower by length and weight respectively, than in constant 21 °C controls. Limitations in growth were associated with increases in indicators of the physiological stress response. Individuals exposed to 22 or 24 °C for 24 days exhibited plasma cortisol levels that were 12 and 18 fold greater than at 16 °C. Similarly, gill heat shock protein (Hsp)-70 levels were 10.7 and 56 fold higher at 22 and 24 °C than at 16 °C. Brook trout exposed to daily temperature oscillation of 4 or 8 °C had gill Hsp-70 levels that were 40 and 700 fold greater than controls. Acute (6 h) temperature exposures were used to demonstrate a threshold for induction of the Hsp-70 and plasma glucose responses of 20.7 °C and 21.2 °C respectively. Finally, we conducted field surveys that demonstrated increased plasma cortisol, plasma glucose, and gill Hsp-70 at temperatures above 21 °C. Induction of the cellular and endocrine stress responses is associated with decreased growth in brook trout. Thermal limitations on growth may provide a mechanism by which temperature drives the distributions of this cold-water species.

This book was released on 2017 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early developmental stages of cold-adapted ectotherms such as brook trout (Salvelinus fontinalis) are atrisk of mortality with increasing water temperatures because of their sensitivityto changes in their environment.I studiedthe mass and routine metabolic rate(RMR) of wild-origin brook trout eggs, alevin and young fry reared at normal (5°C) and elevated (9°C) temperaturesfor the duration of the study or at mismatched temperatures.This setup determinedif preconditioning acclimation for one temperature benefits or hinders the organism later in life.Three levelsof biological organization (ancestry, population, family) were studied using Akaike?sInformation Criterion (AIC) to identify models that best accountedforvariation in thedata.Family, massand temperature were most important inpredictingbody mass and mass-adjustedRMR, although population and ancestral-level differences were also detected atsome life stages.Strongvariation in body mass and mass-adjusted RMRamong families may indicate adaptive potential within brook trout populations to respond to increases in water temperaturewithclimate change.Keywords: Temperature, physiology, brook trout, Salvelinus fontinalis, thermal tolerance, acclimation, routine metabolic rate, environmental matching, AIC.

Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume brings out a comprehensive collection of information on environmental toxicology, its impact on living organisms in general and human health in particular. The main focus of this book is to address human health issues and risk assessment. Toxicological studies help in understanding the impact of harmful substances including both natural and synthetic chemicals on organisms and their environment. Contributions in the title include both laboratory and field based studies with a focus on human health. Moreover, day by day, there is an increase in the range of chemicals from pharmaceutical and other industries, agricultural runoffs, medicine, and many other sources which continuously contribute to the earth's chemical load. Almost all the countries are facing great difficulties in responding to the crucial and immediate need for effective management of such contaminants. The title compiles studies in regards to environmental toxicology and its effect on human health. This book provides critical information and knowledge that can be used by regulatory agencies, decision-makers, policy makers, graduate and post-graduate students, researchers, environmental toxicologists, etc, and others to put programs and policies in place to limit our exposures to these substances thereby preventing or reducing the likelihood that a disease or other negative health outcomes would occur.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This text is divided into three parts. The first part describes basic toxicological concepts and methodologies used in aquatic toxicity testing, including the philosophies underlying testing strategies now required to meet and support regulatory standards. The second part of the book discusses various factors that affect transport, transformation, ultimate distribution, and accumulation of chemicals in the aquatic environment, along with the use of modelling to predict fate.; The final section of the book reviews types of effects or endpoints evaluated in field studies and the use of structure-activity relationships in aquatic toxicology to predict biological activity and physio-chemical properties of a chemical. This section also contains an extensive background of environmental legislation in the USA and within the European Community, and an introduction to hazard/risk assessment with case studies.
