Book excerpt: Climate change is increasing temperatures globally as well as the frequency and severity of extreme events such as heat waves. Given that the majority of animals on Earth are ectothermic, and therefore physiologically linked to environmental temperatures, it is imperative to predict the impacts of future warming on species. The physiological effects of warming on ectotherms have been studied extensively, yet, species interactions can also be affected by temperature. My thesis assessed how differences in species' responses to warming affect their interactions and ultimately the structure and dynamics of communities. I first asked if phenological and early developmental responses to warming differed among and within dragonfly species. Warming accelerated growth and developmental rates, however, differences were greater within as opposed to between species in these responses. I also examined whether differences in behavioural responses to warming among species could determine which species became the superior IG predator. Foraging and IGP rates increased with warming but activity level changes were not predictive of the outcome of these interactions. Next, I asked how the interactive effects of warming and predator presence affected prey foraging decisions. Warmer conditions appeared to have a greater impact on prey behaviour that the predator presence, even though the prey's risk of being eaten increased with temperature. Lastly, I manipulated developmental conditions in pond mesocosms to understand how warming and heat waves affect community structure. Heat waves similarly increased species' evenness in communities as warming. However, heat waves further boosted survival compared to ambient and warmed conditions, strengthening consumption on primary consumers within these food webs. Together, my thesis demonstrates the importance of understanding complex interactions between species to make more accurate predictions of the effects of future warming on communities.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Using a forested headwater stream system as a model, the effects of inter-annual variation in summer discharge regimes on aquatic insect communities were investigated. More specifically, the benthic invertebrate community response to the intensity, minimum discharges, frequency, duration and abruptness of summer low-flow events were examined. We hypothesized that intensification of summer low-flow events, both in duration and magnitude, have some negative impacts on benthic macroinvertebrate communities in riffles. Examples of negative impacts include reduction in their abundance and/or biodiversity. First, the abundance and functional trait data of the benthic macroinvertebrates in the three streams in the Malcolm Knapp Research Forest, British Columbia, Canada, were analyzed with respect to the low-flow events. Second, population models were built to simulate the potential responses of lotic aquatic insect communities to future climate change scenarios that differ in the rate of intensifications in extreme flow events: a low-flow event scenario within the current range versus 10% increase in intensity. The summer low-flow events were found to have a significant relationship with benthic macroinvertebrate communities through three-table ordinations of the empirical data. The community structure was correlated with a major ocean-atmosphere regime shift (Pacific Decadal Oscillation). The intensity and duration of low-flow events explained the observed shift in community structure favouring r-selected traits (e.g. short life cycle, high reproduction rate). The two low-flow severity scenarios showed the significant differential impacts on the aquatic insect community structures when individual populations were modeled according to their traits. Aquatic insects could be separated into three groups according to their sensitivities, measured by extinction rates, toward the two scenarios.

Book excerpt: Caterpillars are excellent model systems for the investigation of insect-plant interactions, predator-prey interactions, and insect physiology. Despite this, however, there is at present only a limited understanding of the constraints on foraging patterns of caterpillars. A major problem is the difficulty of designing and analyzing experiments which account for multiple constraints. Caterpillars: Ecological and Evolutionary Constraints on Foraging reviews the present state of research into caterpillar biology while arguing for a multiple factor approach in studying insect herbivores. Written by leading authorities in entomology and ecology, it provides an explicit framework for carrying out such investigations. The book details the constraints of the foraging patterns of caterpillars, including phylogenetic constraints, the physical environment, nutritional supply and demand, predators, and plant chemical defenses. It also analyzes caterpillar adaptations, such as sociality, mutualism, aposematism, and cryptic morphology, and covers population dynamics and the influence of environmental factors upon tropical, temperate, and arctic caterpillars. The book concludes with a discussion of the implications of this material for pest management, forest systems, and agroecosystems.

With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

Available in PDF, EPUB and Kindle. Book excerpt: Wildlife Responses to Climate Change is the culmination of a three-year project to research and study the impacts of global climate change on ecosystems and individual wildlife species in North America. In 1997, the National Wildlife Federation provided fellowships to eight outstanding graduate students to conduct research on global climate change, and engaged leading climate change experts Stephen H. Schneider and Terry L. Root to advise and guide the project. This book presents the results, with chapters describing groundbreaking original research by some of the brightest young scientists in America. The book presents case studies that examine: ways in which local and regional climate variables affect butterfly populations and habitat ranges how variations in ocean temperatures have affected intertidal marine species the potential effect of reduced snow cover on plants in the Rocky Mountains the potential effects of climate change on the distribution of vegetation in the United States how climate change may increase the susceptibility of ecosystems to invasions of non-native species the potential for environmental change to alter interactions between a variety of organisms in whitebark pine communities of the Greater Yellowstone Ecosystem Also included are two introductory chapters by Schneider and Root that discuss the rationale behind the project and offer an overview of climate change and its implications for wildlife. Each of the eight case studies provides important information about how biotic systems respond to climatic variables, and how a changing climate may affect biotic systems in the future. They also acknowledge the inherent complexities of problems likely to arise from changes in climate, and demonstrate the types of scientific questions that need to be explored in order to improve our understanding of how climate change and other human disturbances affect wildlife and ecosystems. Wildlife Responses to Climate Change is an important addition to the body of knowledge critical to scientists, resource managers, and policymakers in understanding and shaping solutions to problems caused by climate change. It provides a useful resource for students and scientists studying the effects of climate change on wildlife and will assist resource managers and other wildlife professionals to better understand factors affecting the species they are striving to conserve.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Available in PDF, EPUB and Kindle. Book excerpt: Temperature profoundly impacts both the phenotypes and distributions of organisms. These thermal effects exert strong selective pressures on behaviour, physiology and life history when environmental temperatures vary over space and time. Despite temperature's significance, progress toward a quantitative theory of thermal adaptation has lagged behind empirical descriptions of patterns and processes. In this book, the author draws on theory from the more general discipline of evolutionary ecology to establish a framework for interpreting empirical studies of thermal biology. This novel synthesis of theoretical and empirical work generates new insights about the process of thermal adaptation and points the way towards a more general theory. The threat of rapid climatic change on a global scale provides a stark reminder of the challenges that remain for thermal biologists and adds a sense of urgency to this book's mission. Thermal Adaptation will benefit anyone who seeks to understand the relationship between environmental variation and phenotypic evolution. The book focuses on quantitative evolutionary models at the individual, population and community levels, and successfully integrates this theory with modern empirical approaches. By providing a synthetic overview of evolutionary thermal biology, this accessible text will appeal to both graduate students and established researchers in the fields of comparative, ecological, and evolutionary physiology. It will also interest the broader audience of professional ecologists and evolutionary biologists who require a comprehensive review of this topic, as well as those researchers working on the applied problems of regional and global climate change.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change is affecting freshwater ecosystems worldwide. Warming temperatures have had profound impacts on the distribution of organisms, the timing of biological events, and the overall biodiversity of freshwater ecosystems. Much of the recent research investigating the effects of climate warming on freshwater ecosystems has focused on individual fitness and population dynamics. Much less focus has been on higher levels of organization, such as whole communities and food webs. The primary goal of this dissertation was to determine how warming affects community assemblages and the flow of energy through natural food webs. To address this, I used a whole-stream warming experiment in which I experimentally warmed an entire stream reach in Iceland by approximately 3.5°C using a geothermal heat exchanger, and examined the response of invertebrate communities in the warmed stream and a nearby reference stream for 1 year prior to warming and 2 years during warming. Overall, warming altered invertebrate community structure and significantly reduced total community abundance, while total biomass and production remained unchanged. Warming also resulted in increased energy demand by the invertebrate community but no concomitant increase in resource consumption. Neutral effects of warming on total community biomass, production, and resource consumption were largely driven by declines in several small-bodied, cold-adapted taxa and concurrent increases in many larger, warm-adapted taxa, including newly invading species. Overall, our experimental results demonstrate that warming affects stream communities via exchange and relative success of species according to thermal physiology, and that shifts towards smaller body size are not a universal response to warming. Generalizing these results to global anthropogenic warming has important consequences for the future of aquatic communities and food webs.
