Book Description
In the project we show that climate change is not only affecting a few individual species or habitats in the Nordic region, but that number of changes occur concurrently and at many scales.

Book Description
The Nordic countries have agreed on a common target to halt the decline in biodiversity by 2010. This report aims at evaluating the 2010-target by presenting indicators that can describe trends in biodiversity in the Nordic countries. Our results comprise the most comprehensive documentation of land use in the Nordic countries to date. The area of important nature types such as mire, grassland and heathland have decreased significantly over the past one to two decades, whereas the area of constructed habitats, including city areas and transport networks, has grown considerably in all of the Nordic countries. Each of these trends in land use will cause biodiversity to decline. Looking into the quality aspect of biodiversity, our results reveal that two-thirds of the quality indicators presented show declines and the remaining one-third show improvements (or steady-state). Overall, our results indicate that biodiversity has declined in the Nordic countries since 1990. In particular, farmland, mire, grassland and heathland habitats show declines in biodiversity, but also the remaining habitats show negative trends. Therefore, based on the findings from this study, we conclude that it is highly unlikely that the target of halting biodiversity loss by 2010 can be achieved by the Nordic countries. Our results should be perceived as a first attempt to make an overall assessment of biodiversity in the Nordic countries. We believe that if further efforts were directed towards scrutinising existing and historic monitoring programmes and data sources, additional indicators could be calculated and hence a better knowledge base would be achieved.

Book Description
A detailed, authoritative yet highly readable monograph on one of Britain's best-loved farmland birds, the Lapwing. With its striking green-black and white plumage and distinctive pee-wit call, the Lapwing is one of Britain's best-known birds. Lapwings depend on agricultural land to breed and are considered a barometer of the health of this habitat; the population has crashed over recent decades, partly due to changes in farming practices. In winter, Lapwings switch to coastal areas and to wetlands, including those in suburban areas, where large, noisy flocks can gather. Michael Shrubb's The Lapwing is a thorough review of Lapwing biology contains sections on population dynamics, feeding ecology, habitat use, migration, and conservation; there is an impressively detailed review of our current understanding of breeding biology, plus discussion of some other species in the genus. The Lapwing is a superb addition to the Poyser list. Of interest to both amateur naturalists, who will enjoy insights into the birds' lives, and to academics, who will appreciate the broad overview of current research, this title will remain the definitive work on the species for many years to come.

Book Description
"An unspoiled region of northern Fennoscandia and northwestern Russia that lies within the Arctic Circle. Laplans holds a fascinating and specialized community of plants and animals. This book is the first to present an in-depth look at the flora and fauna of Lapland. Introductory chapters consider the geography and history of the area as a whole, and the tradition of wildlife study in Lapland. Following chapters focus on the general biogeography and composition of the Lapland flora and fauna, and the ecological strategies of Lapland birds. The wildlife of each distinct Lapland habitat is then considered in detail, with a final section that discusses conservation issues. The text is enhanced by a wealth of color photographs depicting the region's diverse habitats and wildlife."--Jacket.
