Lichens occur in most terrestrial ecosystems; they are often present as minor contributors,
but in some forests, drylands and tundras they can make up most of the ground layer …

This paper reviews characteristics of dispersal that influence metapopulation functioning,
such as releasing factors, density dependence, timing and types and health of dispersers …

Increased amount of edge habitat is one of several important consequences of forest
fragmentation. Consequently, we must understand the responses of plants and animals to …

To maintain biodiversity in managed forests we must understand the patterns and processes
that regulate the occurrence and dynamics of species in undisturbed ecosystems. We …

This chapter deals with the question of maintaining biological diversity in the boreal forests
of Fennoscandia, ie the Scandinavian Peninsula and Finland. The boreal coniferous forest …

We investigated whether dispersal limitation is an important factor for the low abundance of
epiphytic lichens in young boreal forests. The number of lichen thalli on branch sections of …

To maintain biodiversity in managed forests we must understand how forestry affects various
organisms across a wide range of spatial and temporal scales. We compared landscape …

Thin, hair‐like lichens (Alectoria, Bryoria, Usnea) form conspicuous epiphyte communities
across the boreal biome. These poikilohydric organisms provide important ecosystem …

The nutrient contribution of lichens as litterfall in forests is discussed for a number of different
ecosystems and it is hypothesized that lichens are important in capturing nutrients from wet …

Exploration of tree crowns worldwide often reveals rich epiphyte communities composed of
lichens, bryophytes, and vascular plants. In very old, wet forests, nearly every tree surface …
