Book Description
On- strategies organized according to the need to understand climate site land use planning and management techniques must be change, mitigate the impacts of rapid climate change, and help designed to protect the ecological and social pieces, patterns, Ontarians adapt to climate change: and processes. [...] Given the uncertainty in the amount of emissions and associated effects, natural resource management agencies around the world are using a number of climate models and scenarios of human behaviour to depict a range of potential climatic conditions and impacts that may appear in the next 100 years. [...] It is notable that the countries attending the 2005 climate change conference in Montreal to review and discuss future programs under the auspices of the United Nations Framework Convention on Climate Change and the Kyoto Protocol agreed that the development of adaptation tools and techniques should receive significant attention during the next 5 years. [...] Species Distribution and Abundance in Response to Climate Change The distribution and abundance of a species across its geographic range is related to both biotic (e.g., food, competition, and disease) and abiotic (e.g., climate and substrate) factors. [...] There are several ways to examine the effects of climate on terrestrial fauna, and to determine how climate change may affect species and their habitat in the future.

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.

Book Description
Global climate change has the potential to dramatically alter Ontario's terrestrial ecosystems. The authors of this paper have identified three general classes of mechanisms that can affect species as a result of climate change: demographic, phenological, and genetic. Each of these classes can cause population expansions or contractions depending on the ecology of particular species. To demonstrate the range of potential climate effects, they present case studies for deer tick (Ixodes scapularis), moose (Alces alces), eastern bluebird (Sialia sialis), polar bear (Ursus maritimus), red squirrel (Tamiasciurus hudsonicus), and black-capped chickadee (Poecile atricapillus). They also summarize a review of climate change studies of vertebrate species that occur in Ontario. This report is 1 of 10 prepared in support of Ontario Ministry of Natural Resources' strategic assessment of its climate change program.

Book Description
Changes in air temperatures, precipitation patterns, and extreme weather events associated with climate change have and will continue to influence aquatic ecosystems. Increased water temperatures, changes in the timing of the spring freshet, the duration of ice-cover, and the composition of wetlands have been already documented in several systems. Lake Simcoe and the wetlands and streams within the Lake Simcoe Watershed are also being affected by climate change. The objectives of this study were to (1) use ecological indicators to assess the potential effects of climate change and (2) apply those results to inform the development of a climate change adaptation strategy for aquatic ecosystems within the Lake Simcoe Watershed. For each ecosystem, physical habitat changes associated with climate change were paired with a biological indicator.--Document.

Book Description
"Climate change is impacting aquatic ecosystems in the Great Lakes Basin (GLB). Surface water temperatures of the Great Lakes, inland lakes and streams are on the rise, water levels are in decline, and the composition of plant and animal communities in wetlands are changing. The objectives of this study were to assess the vulnerability of different indicators; wetland vulnerability to drying, wetland bird species habitat, stream temperatures, stream thermal habitat, inland lake surface temperatures, and walleye biomass, to inform the development of a climate change adaptation strategy for aquatic ecosystems within the GLB of Ontario. Climate models forecast a 4 to 6 degrees C warming of mean annual air temperatures and regional changes in precipitation by the end of the century."--Summary.

Book Description
New focused text introduces readers to wetland ecosystems and systems approaches to studying wetlands With its comprehensive coverage of wetland science, management, and restoration, Mitsch and Gosselink's Wetlands has been the premier reference on wetlands for more than two decades. Now, the coverage of specific wetland ecosystem types from earlier editions of this acclaimed work has been updated, revised, and supplemented with additional content in order to create this new text focusing exclusively on wetland ecosystems. This book now complements Wetlands, Fourth Edition. Following an introduction to ecosystems in general and wetland ecosystems in particular, Wetland Ecosystems examines the major types of wetlands found throughout the world: coastal wetlands, freshwater marshes and forested swamps, and peatlands. The final chapter reviews three fundamental systems approaches to studying wetlands: mesocosms, full-scale experimental ecosystems, and mathematical modeling. This new text features: Updated descriptions of the hydrology, biogeochemistry, and biology of the main types of wetlands found in the world New content introducing general ecosystems, wetland ecosystems, whole ecosystem and mesocosm experiments with wetlands, and systems ecology and modeling A detailed description of the ecosystem services provided by wetlands A broad international scope, including many examples of wetlands located outside North America Two new coauthors offering new perspectives and additional insights into the latest ecosystem and modeling techniques An abundance of illustrations helps readers understand how different biological communities and the abiotic environment in wetland ecosystems interact and function. Tables and text boxes provide at-a-glance summaries of key information. Lastly, each chapter concludes with a list of recommended readings. This text has been designed as an introduction for students and professionals in wetland ecology and management, general ecology, environmental science, and natural resource management.

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.
