Book Description
About 50 species of shorebirds breed in the Arctic, where they constitute the most characteristic component of the tundra avifauna. Here, we review the impact of weather and climate on the breeding cycle of shorebirds based on extensive studies conducted across the Arctic. Conditions for breeding shorebirds are highly variable among species, sites and regions, both within and between continents. Weather effects on breeding are most moderate in the Low Arctic of northern Europe and most extreme in the Siberian High Arctic. The decision of whether or not to breed upon arrival on the breeding grounds, the timing of egg-laying and the chick-growth period are most affected by annual variation in weather. In large parts of the Arctic, clutch initiation dates are highly correlated with snowmelt dates and in regions and years where extensive snowmelt occurs before or soon after the arrival of shorebirds, the decision to breed and on the breeding ecology of clutch initiation dates appear to be a function of food availability for laying females. Once incubation is initiated, adult shorebirds appear fairly resilient to variations in temperature with nest abandonment primarily occurring in case of severe weather with new snow covering the ground. Feeding conditions for chicks, a factor highly influenced by weather, affects juvenile production in most regions. Predation has a very strong impact on breeding productivity throughout the Arctic and subarctic, with lemming Dicrostonyx spp. and Lemmus spp. fluctuations strongly influencing predation rates, particularly in the Siberian Arctic. The fate of Arctic shorebirds under projected future climate scenarios is uncertain, but High Arctic species and populations appear particularly at risk. Climatic amelioration may benefit Arctic shorebirds in the short term by increasing both survival and productivity, whereas in the long term habitat changes both on the breeding grounds and on the temperate and tropical non-breeding areas may put them under considerable pressure and may bring some of them near to extinction. Their relatively low genetic diversity, which is thought to be a consequence of survival through past climatically-driven population bottlenecks, may also put them more at risk to anthropogenic-induced climate variation than other avian taxa.

Book Description
The Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the ‘changing Arctic’, especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective. This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about. Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic. About the Editor David N. Thomas is Professor of Arctic Ecosystem Research in the Faculty of Biological and Environmental Sciences, University of Helsinki. Previously he spent 24 years in the School of Ocean Sciences, Bangor University, Wales. He studies marine systems, with a particular emphasis on sea ice and land-coast interactions in the Arctic and Southern Oceans as well as the Baltic Sea. He also edited a related book: Sea Ice, 3rd Edition (2017), which is also published by Wiley-Blackwell.

Book Description
"/i/Arctic Shorebirds in North America//i/ represents a study that is one of the remarkable achievements of wildlife fieldcraft, like those done by Aldo Leopold in the 1930s and by the Craighead Brothers in the 1960s. To conduct a study of this scientific caliber in the great expanse and harsh climate of the Arctic makes it one of the great wildlife investigations whose value will only grow with time."--Larry Niles, Conserve Wildlife Foundation of New Jersey "It is most timely that Jonathan Bart and Victoria Johnston have gathered information on shorebirds that breed in the Arctic regions of North America. Data on these birds is generated at a wide range of locations by many different individuals and teams, and this book puts it into perspective. It is particularly valuable to have this treatise when so many shorebird species worldwide are in marked decline."--Clive Minton, Australasian Wader Studies Group "When the PRISM program for pan-Arctic shorebird monitoring was introduced, everyone agreed with its laudable aims, but it seemed impractical. How could shorebird biologists with limited time and resources acquire robust data on the size and trend of shorebird populations across the American Arctic? Now, the credibility gap has been bridged. /i/Arctic Shorebirds in North America//i/ presents the rigorous, practical methods that will be the foundation of Arctic shorebird monitoring for years to come. I look forward to Arctic PRISM becoming the keystone of shorebird conservation in the Western Hemisphere."--Humphrey Sitters, editor of /i/Wader Study Group Bulletin//i/

Book Description
Shorebirds are the most visible inhabitants of coastal wetlands worldwide. Many undertake spectacularly long flights between their wintering and breeding grounds, embodying the miracle of long-distance migration in a profound way. In this illustrated behavioural ecology the migration, feeding and breeding of these birds are explained in a comprehensive but simple and visually stunning form. The core of the book is based on studies of shorebirds and other waterbirds (such as ducks, geese and gulls) that migrate along the East Atlantic Flyway. The emphasis is on those using the Dutch, German and Danish Wadden Sea; examples from the rest of the world are also included. The authors are experts in the fields of bird migration, shorebird behaviour and intertidal ecology, and have contributed much to our current understanding of these subjects. The 300 magnificent portraits of waterbirds in action were taken by Jan van de Kam, one of The Netherlands' foremost wildlife photographers.

Book Description
Climate change is having an increasing impact on coastal, estuarine, and marine environments worldwide. This book provides state-of-the-art coverage of climate change effects on estuarine ecosystems from local, regional, and global perspectives. With editors among the most noted international scholars in coastal ecology and estuarine science and contributors who are world-class in their fields, the chapters in this volume consist of comprehensive studies in coastal, estuarine and marine sciences, climate change, and coastal management and provide an extensive international collection of data in tabular, illustrated, and narrative formats useful for coastal scientists, planners, and managers. Comprised of three sections: (1) physical-chemical aspects; (2) biological aspects; and (3) management aspects, the book not only examines climatic and non-climatic drivers of change affecting coastal, estuarine, and marine environments but also their interactions and effects on populations of organisms, communities, habitats, and ecosystem structure and function. Pulling together today’s most salient issues and key literature advances for those concerned with coastal management, it allows the reader to see across direct and indirect interactions among disciplinary and ecosystem boundaries. Climate Change and Estuaries meets the research needs of climate scientists, estuarine and marine biologists, marine chemists, marine geologists, hydrologists, and coastal engineers, while students, professors, administrators, and other professionals will also find it an exhaustive reference.
