Effects Of Climate Variation On The Breeding Ecology Of Arctic Shorebirds

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.

The 40 or so species of beach-loving plovers (genus Charadrius) comprise a diverse group of shorebirds found around the world. Most of these species are challenged by changing climates and other human-related development activities, yet they provide key insights into basic ecological and evolutionary processes. The expert international contributors take a comparative approach, presenting examples from many worldwide plover studies and synthesizing the group’s most pressing and important topics. The book further presents an emphasis on full life-cycle biology, including the importance of examining migratory connectivity issues, even for non-migratory plovers.

“Until recently, inferring identities of predators and monitoring cryptic behaviors at the nest was time-consuming, often with anecdotal results. No more. Video nest surveillance, so aptly revealed in this volume, has ushered in a new era of data collection that allows field workers to link environmental factors with such aspects as the temporal dynamics of predator communities in relation to what the birds are doing at their nests, thus removing much of the guesswork of earlier studies.”--Spencer G. Sealy, University of Manitoba "Video Surveillance of Nesting Birds shatters earlier beliefs about how birds interact with nest predators. Much of what we thought we knew about nesting and its hazards was flat-out wrong, as authors in this book discovered by using modern technology in the field. As simple as we would like our models of animal behavior to be, this book shows that reality is far more complex and nuanced."--Douglas H. Johnson, University of Minnesota

A critical synthesis of the impacts of climate change on birds, examining potential future effects and conservation responses.

"/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/

'The ability of the birds to show us the consequences of our own actions is among their most important and least appreciated attributes. Despite the free advice of the birds, we do not pay attention', said Marjory Stoneman Douglas in 1947. From ice-dependent penguins of Antarctica to songbirds that migrate across the Sahara, birds' responses provide early warning signs of the impact of climate change. Winged Sentinels: Birds and Climate Change uses colourful examples to show how particular groups of birds face heightened threats from climate change and to explore how we can help birds adapt in a warming world. Generously illustrated with colour photographs, the book is a fascinating insight into what climate change means for birds, and the potential consequences of ignoring these warning signs.
