The lands surrounding the North Atlantic Region (the SCANNET Region) cover a wide range of climate regimes, physical environments and availability of natural resources. Except in the extreme North, they have supported human populations and various cu

Community pattern concerns the spatial heterogeneity, both vertical and horizontal, of climate, soil, vegetation and fauna of forests. The observed pattern is dominated by the trees themselves but to what extent and in what way do the trees determine

Using a bioassay approach, this paper considers the nitrogen-supplying power of forest floors from examples of the major forest types in interior Alaska. Yield and net N uptake by paper birch seedlings grown in standardized mixtures of quartz sand an

Following recent reviews on nutrient cycling in temperate and British forests, two aspects of N cycling are selected for examination because of their fundamental importance and their relevance to management—ecosystem research and mobilization of N

The aim of the grassland and moorland studies was to measure primary and secondary production and to describe the main pathways of dry matter and nutrients within these ecosystems. The strategy was to make detailed studies on two main sites (Snowdoni

The growth of fungi isolated from a lowland temperate site (Roudsea Wood National Nature Reserve), an upland temperate moorland (Moor House National Nature Reserve) and an oceanic Antarctic island (Signy, S. Orkneys) was compared at 1, 14 and 25°C.
