Book Description
With detailed essays on the Arctic's environment, wildlife, climate, history, exploration, resources, economics, politics, indigenous cultures and languages, conservation initiatives and more, this Encyclopedia is the only major work and comprehensive reference on this vast, complex, changing, and increasingly important part of the globe. Including 305 maps. This Encyclopedia is not only an interdisciplinary work of reference for all those involved in teaching or researching Arctic issues, but a fascinating and comprehensive resource for residents of the Arctic, and all those concerned with global environmental issues, sustainability, science, and human interactions with the environment.

Book Description
The Nordic subarctic-subalpine birch forest belt is unique to Fennoscandia, the Kola Peninsula, Iceland and southern Greenland. The area is characterized by extensive multiple use, including reindeer husbandry, forest and tourist industries and hunting and fishing. Scientifically, the mountain birch has been of special interest from a genetic and ecological angle, including the use of experimental approaches to assess the effects of phylogenesis and environment on biological performance. Such approaches lie at the core of the studies in this volume.

Book Description
Phytogeographically and climatically West Greenland includes parts of the low arctic and high arctic areas. The present vegetation and a summary of its history since the last glaciation based on pollen and macrofossil analyses are briefly described. The determination of more than 55,000 herbarium sheets of native phanerogams has been checked. Before preparing the dot maps it was necessary to decide at which level taxonomically difficult genera (eg: Antennaria, Draba, Poa, Puccinellia, and Stellaria would be treated). For all of these the criteria used are given. Dot maps have been prepared for 379 taxa. These maps have been grouped into 11 West Greenland distribution types, which clearly correlate with T W Böcher's biological distribution types (Böcher 1963). The collecting intensity in the large area is rather uneven. This is illustrated by a map giving the number of collections at the 305 localities from which 50 or more collections are at hand. Another map giving the number of taxa at 29 well-investigated localities illustrates the species diversity in the region. Most low arctic localities have more than 130 taxa, with 215 at the richest locality (Godhavn / Qeqertarsuaq on Disko), while the number at no high arctic locality exceeds lS0. Reference to the corresponding numbers in other parts of Greenland is given. Based on the dot maps a new delimitation of West Greenland in floristic provinces and districts is presented. It differs somewhat from that in Grønlands Flora / The Flora of Greenland (Böcher et al. 1957, and later editions). The major alteration is that the boundary between the low and high arctic phytogeographic provinces is now placed through north Disko - Nuussuaq. As a consequence of this the southernmost district in the high arctic is divided into an outer (NWso) and an inner province (NWsi). Minor alterations are suggested in the southern part of West Greenland.
