11. Foliar fungi of Scots pine (Pinus sylvestris)
Sammanfattning : Scots pine (Pinus sylvestris) is an ecologically and economically important tree species in Fennoscandia. Scots pine needles host a variety of fungi, some with the potential to profoundly influence their host. These fungi can have beneficial or detrimental effects with important implications for both forest health and primary production. LÄS MER
12. Forest restoration using direct seeding of oak – Odor cues from predators as a seed protection strategy against foraging rodents
Sammanfattning : In forest restoration of oak, planting nursery-growth seedlings is related to high operational costs. One cost-efficient alternative is the application of direct seeding. However, acorn removal by rodents is one of the major drawbacks in its implementation. LÄS MER
13. Tree stem diameter estimation from terrestrial point clouds
Sammanfattning : Forest owners, governments, and environmental organizations demand forest information for planning of forest operations, estimation of value, and for environmental monitoring. This information is collected using airborne and satellite remote sensing combined with field inventory of sample plots. LÄS MER
14. The importance of tree cover for water resources in semiarid West Africa
Sammanfattning : The current paradigm in forest hydrology implies that an increase in tree cover always leads to reduced water yields as a result of increased interception and transpiration (ET) losses. This trade-off theory, in which more trees mean less water, has led to concerns that the establishment of trees in drylands may jeopardize scarce water resources. LÄS MER
15. Oak as retention tree in commercial spruce forests : effects on species diversity of Saproxylic beetles and wood production
Sammanfattning : Retaining trees valuable for biodiversity is a common conservation measure. There are indications that such trees have important benefits for the diversity of many species groups. However, retaining trees may also have negative effects on timber production. LÄS MER
