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
Certain species considered provincially rare in the Lake Simcoe watershed including some listed as threatened or endangered under Ontario's Endangered Species Act (Statutes of Ontario 2007), may be at risk of extirpation due to adverse effects of natural and/or anthropogenic stressors. Climate change, acting alone or in combination with other stressors, may pose an important emerging threat for many of these species. Several tools to assess climate change effects are being developed for use by resource managers to categorize the relative vulnerability of selected species to climate change. In response to the Lake Simcoe Protection Plan, Ontario's Adaptation Strategy and Action Plan: 2011-2014, and the Ministry of Natural Resources' Climate Change Strategy, vulnerability assessments have been completed for selected natural assests in the Lake Simcoe watershed. By testing the model against a subset of high priority provincially rare species found within the Lake Simcoe watershed the authors objectives were to: categorize the relative vulnerability of each species; identify species-level indicators that are useful for assessing vulnerability to climate change; identify the key factors causing species vulnerability.--Document.

Book Description
This is a print on demand edition of a hard to find publication. Water from forested watersheds provides irreplaceable habitat for aquatic and riparian species and supports our homes, farms, industries, and energy production. Yet population pressures, land uses, and rapid climate change combine to seriously threaten these waters and the resilience of watersheds in most places. Forest land managers are expected to anticipate and respond to these threats and steward forested watersheds to ensure the sustained protection and provision of water and the services it provides. Contents of this report: (1) Intro.; (2) Background: Forests and Water; Climate Change: Hydrologic Responses and Ecosystem Services; (3) Moving Forward: Think; Collaborate; Act; (4) Closing; (5) Examples of Watershed Stewardship.

Book Description
Global Climate Change presents both practical and theoretical aspects of global climate change from across geological periods. It addresses holistic issues related to climate change and its contribution in triggering the temperature increase with a multitude of impacts on natural processes. As a result, it helps to identify the gaps between policies that have been put in place and the continuously increasing emissions. The challenges presented include habitability, biodiversity, natural resources, and human health. It is organized into information on the past, present, and future of climate change to lead to a more complete understanding and therefore effective solutions. Placing an emphasis on recent climate change research, Global Climate Change helps to bring researchers and graduate students in climate science, environmental science, and sustainability up to date on the science of climate change so far and presents a baseline for how to move into the future effectively. Addresses the variety of challenges associated with climate change, along with possible solutions Includes suggestions for future research on climate change Covers climate change holistically, including global and regional scales, ecosystems, agriculture, energy, and sustainability Presents both practical and theoretical research, including coverage of climate change over various geological periods

Book Description
HANDBOOK OF CATCHMENT MANAGEMENT In 2010, the first edition of the Handbook of Catchment Management provided a benchmark on how our understanding and actions in water management within a catchment context had evolved in recent decades. Over ten years on, the catchment management concept is entering a new phase of development aligned to contemporary and future challenges. These include climate change uncertainty, further understanding in ecological functioning under change, the drive for a low-carbon, energy efficient and circular society, multiple uses of water, the emergence of new pollutants of concern, new approaches to valuation, finance and pricing mechanisms, stewardship and community engagement, the integration of water across the Sustainable Development Goals (SDG) and the link between water, energy and food. These developments are framed within an increasingly data rich world where new analytics, sensor technology and processing power are informing increasingly real-time decision making. The challenge is also to increase cross-compliance and policy integration to meet multiple stakeholder objectives, and to link actions to achieve cost-effective outcomes. In addition, there are a number of new and exciting city, region and basin-scale real-world examples of contemporary and new catchment thinking; integrating science, technology, knowledge and governance to address multiple drivers and complex problems from across the globe. The time is now right, to capture the new challenges facing catchment management and water resources management globally. This revised and updated edition of the Handbook of Catchment Management features: Thoroughly rewritten chapters which provide an up-to-date view of catchment management issues and contexts New case study material highlighting multi-sectoral management in different globally significant basins and different geographical locations Up-to-date topics selected for their resonance not only in natural sciences and engineering, but also in other fields, such as socio-economics, law and policy The Handbook is designed for a broad audience, but will be particularly useful for advanced students, researchers, academics and water sector professionals such as planners, consultants and regulators.

Book Description
Most research in the Lake Simcoe watershed (LSW) has focused on how the lake has responded to changes in nutrients sourced by agriculture, particularly after mitigation measures have been put in place to remedy the lake's water quality. Nutrient sources from urban areas are not well understood, yet 31% of phosphorus originates from urban tributaries, despite urban land-use accounting for only 12% of total watershed area. Since many urban areas are seeing drastic human population growth and intensification, the impact urban derived stressors have on water quality and biotic communities requires further investigation. The research presented here explored the links between land-use, periphyton nutrient content and biomass, and invertebrate response in lotic surface waters in the LSW. To infer the contribution of cosmetic fertilizer use in the LSW, a community survey was conducted to assess lawn care and fertilizer choices by residents. Overall, the survey results confirmed that cosmetic fertilizer application posed a significant issue in the LSW. The effects of land-use, season, and abiotic parameters on periphyton biomass, nutrient content, invertebrate abundance and biotic composition were investigated using artificial and natural substrates at 14 field sites that represent a gradient from reference to agriculture to urban land-uses. Two consecutive years of sampling found that water quality, particularly nitrate and chloride, from urban land-uses was the same or worse as compared to reference and agriculture land-uses. There was not an increase in periphyton biomass nor change in indicator taxa at urban sites, potentially due to light availability and/or chloride. There was a periphyton nutrient content response between land-uses, however, potential drivers varied. Exploring relationships between established periphyton and invertebrate abundance determined that herbivores exhibited negative relationships with abiotic and biotic predictors, however these varied with season and land-use. The results did highlight that periphyton studies require investigation throughout the complete ice-free year in temperate climates because single season sampling may yield incorrect or incomplete conclusions.

Book Description
This thesis focuses on 3 Ontario water bodies (Hamilton Harbour, the Bay of Quinte and Lake Simcoe), which are vital for economic and recreational activities, yet are threatened by eutrophication, which leads to low dissolved oxygen concentrations (hypoxia) and harmful algae blooms. Among them, Hamilton Harbour and Bay of Quinte are listed as Great Lakes Areas of Concerns (AOCs). To develop effective Remedial Action Plans (RAPs) the potential impacts of climate change on the water quality problems must be assessed. The main objective of this study is to predict the effects of future climate change on the water quality and the implications for lake restoration through computational modeling. A vertical one-dimensional (1D) computational model, Dynamic Reservoir Simulation Model (DYRESM) coupled to Computational Aquatic Ecosystem Dynamics Model (CAEDYM) was applied to Lake Simcoe and Hamilton Harbour. We forecasted the response of the Lake to two greenhouse gas GCM emissions scenarios (A2 and B1). There is a relatively small difference between A2 and B1 predictions. According to the simulations, Lake Simcoe will be stratified 4.5 days per decade longer until 2100 and the length of hypoxia will increase from 55 days to ~100 days. Hamilton Harbor, will be stratified approximately 6 days per decade longer by 2100 and the hypoxic period is projected to increase from 150 days to 200 days. In Lake Simcoe, the mean surface cyanobacteria biomass during the stratified season is simulated to increase from ~ 0.2 ugL-1 to ~1 ug L-1 by 2066 as a consequence of a warming climate. The three-dimensional (3D) hydrodynamic Estuary and Lake Computer Model (ELCOM) combined with CAEDYM was applied to Bay of Quinte. The model results were comprehensively validated against the observed physical (temperature), chemical (nutrients) and biological (phytoplankton biomass) parameters. The model was then forced for the periods of 2000-2004 and 2066-2070, with North American Regional Climate Change Assessment Program (NARCCAP) meteorological data. The simulations show an increase in surface temperature of 2-3.5· C with minimal simulated effects on cyanobacteria. The average May-October TP concentrations in present and future simulations are higher than the RAP target (~0.1 mg L-1), from loads to the upper Bay, and biomass is consistently below the RAP target range (
