Vi må ha en alvorsprat om skogen, for den er så mye mer enn bare trær! Bli med forsker Fride Høistad Schei og lær mer om hvor viktig skogen er og hvorfor det er så mye uenigheter om hvordan skogen skal brukes.

The order Ophiostomatales includes many species important for forestry, causing plant diseases. They are common associates of bark- and wood-dwelling beetles. Two new ophiostomatalean fungi viz. Ophiostoma babimostense sp. nov. and Sporothrix europaea sp. nov. are proposed, based on morphological characters and multigene phylogenies. Ophiostoma babimostense belongs to the Ophiostoma ulmi species complex and was isolated from fallen shoots of Scots pine pruned by Tomicus species in Poland. The fungus is characterised by the production of a typical pesotum-like and sporothrix-like asexual morphs. Sporothrix europaea belongs to the Sporothrix gossypina complex and was isolated from hardwood-infested by ambrosia and bark beetles in Poland and Norway. It is characterised by the occurrence of both a sexual and asexual morphs, with long necked ascomata bearing ostiolar hyphae and a sporothrix-like asexual morph.

Medicinal plants are a vital global resource, and controlled cultivation offers a promising avenue for maximizing the therapeutic potential of phytochemicals. Growing medicinal plants in environments such as vertical farming facilities allows for the production of plants with predictable levels of biologically active compounds, crucial for the pharmaceutical industry. However, current cultivation protocols in vertical farms typically prioritize biomass production over the stimulation of secondary compound accumulation. This situation creates a dilemma: can we grow these plants in a way that both the plant size and the chemical content are optimized? This review examines two examples of external triggers that induce the accumulation of secondary compounds with minimal impact on biomass. The first, root illumination, enhances the accumulation of artemisinin in the shoot without affecting its levels in roots. The second, heterogeneous nutrient supply, does not significantly alter artemisinin accumulation in Artemisia annua leaves but does increase its exudation from roots under nutrient-deficient conditions, particularly with nitrogen and phosphorus. Conversely, localized iron deficiency specifically boosts artemisinin accumulation in the roots. Future research should focus on elucidating the molecular mechanisms behind these responses and exploring additional environmental factors that can be optimized in vertical farming systems to enhance the phytochemical yield of medicinal plants.

Det er forsket en del på reirrøving hos skogsfugl. Men hvilke rovdyr forsyner seg mest av voksen fugl? Radiomerkede storfugl på Varaldskogen kan gi oss en liten pekepinn
Sammendrag
I dag er forskningen på Varaldskogen en av de lengste pågående studiene av skog- og viltøkologi i Norge, om tre år runder vi 50. I etterkant ser vi nå at selv om skogsdriften kan være en negativ faktor, så er det faktisk predasjon på egg, kyllinger og voksne fugler som er den viktigste begrensende faktoren for antall fugl i skogen.

Klimaendringer, med tidligere og varmere vårvær, er positivt for skogsfugl og ryper. Effekten på lang sikt er imidlertid usikker.

The poor persistence and late flowering of red clover in northern Swedish leys presents challenges for ley longevity and floral resource availability. The inclusion of wild, native legume species with longer persistence, rhizomatous growth, and early flowering in leys could help to resolve these challenges. The nutritive value of four native legume species was evaluated when sown in mixed stands subjected to varying harvest frequencies. Across the first two years of data collection, Vicia sepium and Vicia cracca demonstrated promising nutritive value, while the poor digestibility of Lathyrus pratensis may inhibit its use as a forage for ruminant feed. This study demonstrates promising potential for wild legume species to increase ley diversity while maintaining the quality of the harvested forage.
