This book, entitled Tracking Environmental Change Using Lake Sediments: Volume 6 – Sedimentary DNA, provides an overview of the applications of sedimentary DNA-based approaches to paleolimnological studies. These approaches have shown considerable potential in providing information about the long-term changes of overall biodiversity in lakes and their watersheds in response to natural and anthropogenic changes, as well as tracking human migrations over the last thousands of years. Although the first studies investigating the preservation of these molecular proxies in sediments originate from the late-1990s, the number of scientific publications on this topic has increased greatly over the last five years. Alongside numerous ecological findings, several sedimentary DNA studies have been dedicated to understanding the reliability of this approach to reconstruct past ecosystem changes. Despite the major surge of interest, a comprehensive compilation of sedimentary DNA approaches and applications has yet to be attempted. The overall aim of this DPER volume is to fill this knowledge gap.

This is the first book to describe the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. From the lake-rich floodplains of the Arctic to the deep, enigmatic waters of Lake Vostok, Antarctica, these regions contain some of the most extraordinary aquatic ecosystems on Earth. They provide a fascinating diversity of habitats for plant, animal and microbial communities, and are proving to be valuable model systems for exploring many ecological themes including landscape-lake interactions, adaptation of life to environmental extremes, and controls on the structure and functioning of aquatic ecosystems. Some of these waters also have direct global implications, including permafrost thaw lakes as sources of greenhouse gases, subglacial aquatic environments as a storehouse of ancient microbes, and Arctic rivers as major inputs of freshwater and organic carbon to the World Ocean. Given that many polar areas are experiencing greater climate warming than at lower latitudes, these ecosystems can also be viewed as sentinels of global change. This timely volume brings together many of the world's leading researchers in polar limnology to describe these diverse aquatic environments and their ecology. It introduces each major ecosystem type, examines the similarities and differences between Arctic and Antarctic systems as well as their responses to environmental change, and describes new frontiers for future research. A glossary of terms is provided for non-specialists, and a set of colour plates introduces the ecosystems and their biota. Polar Lakes and Rivers will be of value to students and specialist researchers alike, as well as to those with a more general interest in aquatic ecology, polar environments or global change who require an authoritative overview of this fast emerging topic.

Inland aquatic habitats occur world-wide at all scales from marshes, swamps and temporary puddles, to ponds, lakes and inland seas; from streams and creeks to rolling rivers. Vital for biological diversity, ecosystem function and as resources for human life, commerce and leisure, inland waters are a vital component of life on Earth. The Encyclopedia of Inland Waters describes and explains all the basic features of the subject, from water chemistry and physics, to the biology of aquatic creatures and the complex function and balance of aquatic ecosystems of varying size and complexity. Used and abused as an essential resource, it is vital that we understand and manage them as much as we appreciate and enjoy them. This extraordinary reference brings together the very best research to provide the basic and advanced information necessary for scientists to understand these ecosystems – and for water resource managers and consultants to manage and protect them for future generations.

A derivative of the Encyclopedia of Inland Waters, Lake Ecosystem Ecology examines the workings of the lake and reservoir ecosystems of our planet. Information and perspectives crucial to the understanding and management of current environmental problems are covered, such as eutrophication, acid rain and climate change. Because the articles are drawn from an encyclopedia, the articles are easily accessible to interested members of the public, such as conservationists and environmental decision makers. - Includes an up-to-date summary of global aquatic ecosystems and issues - Covers current environmental problems and management solutions - Features full-color figures and tables to support the text and aid in understanding

This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Policy makers and resource managers must make decisions that affect the resilience and sustainability of natural resources, including biodiversity and ecosystem services. However, these decisions are often based on evidence or theory derived from highly altered systems and over short time periods of low-magnitude environmental and climatic change. Because natural systems change and evolve across multiple timescales from instantaneous to millennial, long-term understanding of how past life has responded to perturbations can inform resource managers. By using these natural laboratories of the past, conservation paleobiology and paleoecology provide the framework necessary to anticipate and plan for future changes. The goal of this Research Topic is to heighten awareness among conservation and restoration practitioners to the value and applications of long-term perspectives provided by conservation paleobiology and paleoecology. Most conservation studies focus on systems already impacted by anthropogenic change; these studies would benefit from paleontological data through expanded temporal scales, identification of baselines, and an understanding of how organisms have responded to past changes. However, resource management decisions rarely include input from paleontologists, and paleoecological research is rarely incorporated into conservation decision-making. We seek to bridge this research-implementation gap by highlighting the application of paleoecological data to issues such as biodiversity dynamics, extinction risks, and resilience to perturbations, among other topics. We hope to foster new cross-disciplinary synergies by encouraging conservation scientists and managers to collaborate with paleontologists to improve conservation decision-making and by increasing awareness among paleontologists to the needs of the resource management community. This Research Topic will provide a forum for both the paleontological and resource management communities to exchange ideas that will enhance restoration and conservation decision-making. We invite papers on conceptual advances, reviews of specific topics to guide efforts in research or practice, case studies of successful applications, articles describing datasets with applied value, and perspective papers summarizing a body of paleontological research with relevance to the resource management community. Topics can include but are not limited to: • Responses of species, communities, and ecosystems to perturbations • Strategies to achieve the direct integration of paleobiology and paleoecology into on-ground resource management • Identifying baselines and reference conditions • Increasing the robustness of forecasting models through the incorporation of paleontological data • Identifying key species, interactions, and other phenomena as indicators of impending change • New methodologies, analytical tools, and/or proxies in the application of paleontological data to conservation and restoration practice Lynn Wingard, Damien Fordham, and Greg Dietl have no conflicts of interest. Chris Schneider has a potential conflict of interest where manuscripts pertain to stakeholders in the petroleum industry, as she is an independent contractor in the Alberta Oil Sands mining area.
