Book Description
The boreal forest is one of the world's great ecosystems, stretching across North America and Eurasia in an unbroken band and containing about 25% of the world's closed canopy forests. The Kluane Boreal Forest Ecosystem Project was a 10-year study by nine of Canada's leading ecologists to unravel the impact of the snowshoe hare cycle on the plants and the other vertebrate species in the boreal forest. In much of the boreal forest, the snowshoe hare acts as a keystone herbivore, fluctuating in 9-10 year cycles, and dragging along secondary cycles in predators such as lynx and great-horned owls. By manipulating the ecosystem on a large scale from the bottom via fertilizer additions and from the top by predator exclosures, they have traced the plant-herbivore relationships and the predator-prey relationships in this ecosystem to try to answer the question of what drives small mammal population cycles. This study is unique in being large scale and experimental on a relatively simple ecosystem, with the overall goal of defining what determines community structure in the boreal forest. Ecosystem Dynamics of the Boreal Forest: The Kluane Project summarizes these findings, weaving new discoveries of the role of herbivores-turned-predators, compensatory plant growth, and predators-eating-predators with an ecological story rich in details and clear in its findings of a community where predation plays a key role in determining the fate of individuals and populations. The study of the Kluane boreal forest raises key questions about the scale of conservation required for boreal forest communities and the many mammals and birds that live there.

Book Description
The Yukon is a land of remarkable wilderness, diverse ecosystems, and profound beauty. It is also home to a unique assemblage of birds. As of 2002, 288 bird species have been documented in the Yukon, with 223 occurring regularly. They occupy an amazing range of habitats, from the most barren mountain peaks to lush valley bottom forests, and are an integral part of the cultural heritage of Yukon First Nations people. The vast areas of natural habitat with limited road access can make the study of birds challenging, but are key in defining the nature of birding in the Yukon. Birds of the Yukon Territory is the result of a decade-long project initiated to gather and share what is known about the Yukon's birdlife. Lavishly illustrated with 600 colour photographs and 223 hand-drawn bird illustrations, the book presents a wealth of information on bird distribution, migration and breeding chronology, nesting behaviour, and habitat use, and on conservation concerns. Two hundred and eighty-eight species of birds are documented, including 223 regular species, and 65 casual and accidental species. In compiling this meticulously researched volume, the authors consulted over 166,000 records in a database created by the Canadian Wildlife Service, with information dating back to 1861. S ections on birds in Aboriginal culture and history, and bird names in the Yukon First Nations and Inuvialuit languages, enhance the book, as do the numerous easily interpreted charts and graphs. Destined to become a basic reference work on the avifauna of the North, Birds of the Yukon Territory is a must-have for bird enthusiasts and anyone interested in the natural history of the Yukon and the North.

Book Description
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on Climate Change and Land (SRCCL) is the most comprehensive and up-to-date scientific assessment of the multiple interactions between climate change and land, assessing climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems. It assesses the options for governance and decision-making across multiple scales. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

Book Description
The ecosystems present a great diversity worldwide and use various functionalities according to ecologic regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses of which it was subjected to. Indeed the ecosystems render diverse services to humanity from their composition and structure but the tolerable levels are unknown. The preservation of these ecosystemic services needs a clear understanding of their complexity. The role of research is not only to characterise the ecosystems but also to clearly define the tolerable usage levels. Their characterisation proves to be important not only for the local populations that use it but also for the conservation of biodiversity. Hence, the measurement, management and protection of ecosystems need innovative and diverse methods. For all these reasons, the aim of this book is to bring out a general view on the function of ecosystems, modelling, sampling strategies, invading species, the response of organisms to modifications, the carbon dynamics, the mathematical models and theories that can be applied in diverse conditions.
