Abstract
A combined wood impregnation process including impregnation with a chromium-free wood preservative and oil treatment was evaluated with regard to leaching of copper during the oil process. Two different experimental setups make up the balance of copper content in oil, wood samples and condensate water, also taking different fixation times and process durations into account. Copper is sufficiently fixed after 24 hours, and leaching of copper into the oil is low. Increasing the oil process time does not lead to increased leaching. The hot oil treatment of impregnated wood under vacuum atmosphere is a fast drying method without major negative consequences for the impregnated copper.

Abstract
Blueberries belong to the genus Vaccinium, a widespread genus with more than 200 species of woody plants. In Northern Europe, the European blueberry (EB), also called bilberry, is one of the most important wild berries. EB (Vaccinium myrtillus) is very demanded by the processing industry, due to its delicious taste and high dietary value. However, to our knowledge there has been made no efforts of domestication of the species, and it is still harvested in forest fields without any cultivation. The successful management of the sweet lowbush blueberry (V. angustifolium), which in many ways is similar to the EB, suggests that there are opportunities to increase yield and decrease the significant yearly variation in EB yield, by practices including fertilization, irrigation, cutting trees, and weed control. The fruit yield in wild stands of EB is very variable, but the potential is probably close to 2 tons per hectare. Results from literature on growth of the EB, development and ecology are discussed in relation to possibilities for domestication.

Most basidiomycete fungi produce annual short-lived sexual fruit bodies from which billions of microscopic spores are spread into the air during a short time period. However, little is known about the selective forces that have resulted in some species fruiting early and others later in the fruiting season. This study of relationships between morphological and ecological characteristics, climate factors and time of fruiting are based upon thorough statistical analyses of 66 520 mapped records from Norway, representing 271 species of autumnal fruiting mushroom species. We found a strong relationship between spore size and time of fruiting; on average, a doubling of spore size (volume) corresponded to 3 days earlier fruiting. Small-spored species dominate in the oceanic parts of Norway, whereas large-spored species are typical of more continental parts. In separate analyses, significant relationships were observed between spore size and climate factors. We hypothesize that these relationships are owing to water balance optimization, driven by water storage in spores as a critical factor for successful germination of primary mycelia in the drier micro-environments found earlier in the fruiting season and/or in continental climates.
