The Adaptation and Response of Aquatic Animals in the Context of Global Climate Change


Book Description

Anthropogenic climate change has driven widespread changes in marine environments, including ocean warming, ocean acidification, and the formation of hypoxic zones. Such environmental changes would pose direct challenges to the survival and adaptation of aquatic organisms, greatly affecting the biodiversity of marine life and marine ecosystems. Changes in the marine environment are likely to have strong effects at the physiological, behavioral, and molecular levels, with implications at the individual, population, and species levels, resulting in the degradation of genetic resources through massive mortality. For example, the ingestion, digestion, respiration, and growth of aquatic animals were greatly depressed under extreme environments. In the long run, maintaining a sustainable ocean would require a better understanding of the adaptation of marine animals in response to the effects of multiple environmental stressors. The Research Topic is aimed to discuss the potential impacts of individual and compounded extreme environments on aquatic animals, as well as the regulatory mechanisms and adaptation strategies of marine species to cope with these impacts.




Environmental Physiology of Marine Animals


Book Description

Within recent years man has become increasingly aware of the disastrous environmental changes that he has introduced, and therefore society is now more concerned about understanding the adaptations organisms have evolved in order to survive and flourish in their environment. Because much of the information pertaining to this subject is scattered in various journals or special symposia proceedings, our purpose in writing this book is to bring together in a college-and graduate-student text the principal concepts of the environmental physiology of the animals that inhabit one of the major realms of the earth, the sea. Our book is not meant to be a definitive treatise on the physiological adap tation of the animals that inhabit the marine environment. Instead, we have tried to highlight some of the physiological mechanisms through which these animals have been able to meet the challenges of their environment. We have not written this book for anyone particular scientific discipline; rather, we hope that it will have an interdisciplinary appeal. It is meant to be both a reference text and a text for teaching senior undergraduate and graduate courses in marine biology, physiological ecology of marine animals, and envi ronmental physiology of marine animals.

Book Description




Comparative Reservoir Limnology and Water Quality Management


Book Description

The volume starts with comparative reservoir limnology and deals with problems relating to tropical, semi-arid and temperate reservoirs. The second part concerns mathematical models of reservoirs, including new techniques for investigating their limnology. These cover physical, chemical and biological phenomena, remote sensing and the use of modelling to establish the most efficient strategy for water quality sampling. In the third, on reservoir water quality management, the potential available in fish population management for biomanipulation of reservoir water quality is introduced. Also included is a valuable section on a wide range of water quality measures, coming from the well-known Czech Hydrobiological Laboratory. Finally the editors summarise the present state of reservoir limnology. This book will be of interest to hydrobiologists and aquatic ecologists, reservoir and sanitary engineers, fisheries officers, postgraduate teaching, and the water industry dealing with drinking water supply and will provide insight into regulated rivers. It draws information from all over the world and is relevant to the whole world.







Life at Extremes


Book Description

From arid deserts to icy poles, outer space to the depths of the sea, this exciting new work studies the remarkable life forms that have made these inhospitable environments their home. Covering not only micro-organisms, but also higher plants and animals such as worms, fish and polar plants, this book details the ecological, biological and biogeochemical challenges these organisms face and unifying themes between environments. Equally useful for the expert, student and casual scientific reader, this book also explores the impact of climate change, rapid seasonal changes and pollution on these extraordinary creatures.




Climate Change Impacts on Freshwater Ecosystems


Book Description

This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.




Shrubland Ecosystem Genetics and Biodiversity


Book Description

The 53 papers in this proceedings include a section celebrating the 25-year anniversary of the Shrub Sciences Laboratory (4 papers), three sections devoted to themes, genetics, and biodiversity (12 papers), disturbance ecology and biodiversity (14 papers), ecophysiology (13 papers), community ecology (9 papers), and field trip section (1 paper). The anniversary session papers emphasized the productivity and history of the Shrub Sciences Laboratory, 100 years of genetics, plant materials development for wildland shrub ecosystems, and current challenges in management and research in wildland shrub ecosystems. The papers in each of the thematic science sessions were centered on wildland shrub ecosystems. The field trip featured the genetics and ecology of chenopod shrublands of east-central Utah. The papers were presented at the 11th Wildland Shrub Symposium: Shrubland Ecosystem Genetics and Biodiversity held at the Brigham Young University Conference Center, Provo, UT, June 13-15, 2000.
