Book Description
"This compilation report aims to provide a summary of available information on climate change effects on aquatic life in the Freshwater basins of Canada. An important outcome of this review is a summary of gaps of knowledge. The first chapter is a review of predicted climate induced changes on freshwater fish communities and food webs and details the effects of changes in biotic and abiotic processes on freshwater fish communities and food webs. The second chapter describes the impact that changes in climate are expected to have both directly and indirectly on a variety of fish species and their habitats. The third Chapter describes suitable thermal habitat for stream biota based on different climate variables to assess the potential impacts of climate change on the distribution of coldwater stream fish species in the Great Lakes Basin. The last chapter provides an overview of climate change impacts on water temperature, water chemistry, ice cover, water levels, and productivity. This report provides significant evidence that under a changing climate we can expect significant changes in the spatial extent and duration of preferred thermal habitat for ecologically and economically important fish across the Freshwater region. Warming temperatures expected with climate change will cause areas to approach water temperatures that are no longer thermally optimum for fish species. Species will need to migrate to find suitable habitats and productivity and survival success may decline for some species. Greater habitat overlap may intensify interguild competition and food web interactions. These changes in thermal habitat may intensify top down food web effects"--Abstract.

Book Description
Who Speaks for the Oceans? The question has been asked a lot in recent years - just who is looking out for our oceans? Covering over seventy percent of the earth's surface it is the world's largest common property resource,jojntly owned by over six billion humans. It is the foundation for life on earth as we know it. Over the years, many people have spoken about various aspects of our ocean environments and they have spoken to different audiences in many different ways. For many in the public realm, Jacques Cousteau spoke for the ocean. Since his passing, no single voice with the sallle public identity or recognition has emerged. Certainly the many governments bordering our oceans cannot agree on common principles or issues of ocean use and management. We might be tempted think that we do not have an ocean spokesperson or champion, but we would be wrong. Today, the rapidly growing number of scientists working hard to expand our under standing of our ocean realm are the ocean voices we should listen to. At the same time as our scientists advance their understanding of the oceans, we all need to advance our abilities and commitment to communicate on behalf of the oceans with broader and broader audiences who need to be aware of where things stand. Often called "the last great frontier", earth's oceans are vast, widely varied, and are hard to get to, arid into, to do the research we need done.

Book Description
Freshwater Ecosystems and Climate Change in North America brings together a group of experts from the fields of geochemistry, climatology, hydrology and aquatic ecology to address the central question, What would be the impact to and response of freshwater ecosystems in your region as a result of a hypothetical doubling of CO2 in the atmosphere? These regional papers and syntheses will provide a solid foundation upon which scientists can proceed and build in their efforts to provide other scientists, regulators, and decision-makers with meaningful information concerning the important phenomena associated with climate change.

Book Description
These documents summarize some of the recent studies of the relationships among climate, the aquatic environment, and the dynamics of fish populations. The studies are mostly from the North Pacific ocean, but there are reports of investigations from the North Atlatic Ocean and from fresh water. Various papers include numerous examples of the relationships between fish abundance trends and the environment.

Book Description
Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Book Description
Increases in temperature due to climate change will have large implications for aquatic ecosystems. Warmwater fish species, such as smailmouth bass, Micropterus dolomieu, may have access to additional favourable thermal habitat under increased surface-water temperatures, thereby shifting the northern limit of the distribution of the species further north in Canada and potentially negatively impacting native fish communities. A database comprised of over 50,000 lakes was assembled consisting of data on geography, lake morphology, water chemistry, climate, and fish community composition. Based on a comparison of several statistical approaches (multiple regression, regression tree, artificial neural networks, and Bayesian multiple regression) and several climate-change scenarios, water temperatures were predicted to increase by as much as 18°C by 2100, with the greatest increase in water temperature in northern Canada. By 2100, smallmouth bass thermal habitat is predicted to shift to the north with the majority of Canadian lakes expected to contain suitable thermal habitat. A comparison of logistic regression, classification tree, linear discriminant analysis, and artificial neural networks indicated that smallmouth bass distribution is predicted by winter and summer air temperatures. Climate-change modeling, in conjunction with artificial neural networks, predicted that smallmouth bass will have suitable thermal habitat throughout the majority of aquatic systems in the continental United States and Canada by 2100. The presence of smallmouth bass will negatively impact native fish communities, particularly native lake trout populations. Lake trout populations residing in smaller lakes are more vulnerable to the effects of smallmouth bass establishment due to the decreased presence of alternate prey resources. Examination of the pelagic and littoral forage fish communities identified nearly 9,700 lake trout populations threatened by 2100AD under climate-change scenarios, due to the potential invasion of smallmouth bass. The current range expansion of smallmouth bass has been facilitated by stocking by governmental agencies, unauthorized and accidental introduction by anglers, and dispersal through drainage networks. This stresses the importance of intensifying public education and regulation to limit the potential dispersal of invasive species, such as smallmouth bass.
