Despite the growing use of heritagization in describing how food and food-related practices become cultural heritage, important questions remain regarding what characterizes heritagization and its internal dynamics. This article advances studies on heritagization by applying cultural adaptation work (CAW) to apple festivals. Whereas CAW has been conceptualized within Norway’s regime of geographical indications (GIs) as a rule-bound regulatory institution, we revise and extend that conceptualization by (i) relocating CAW to a hybrid institutional arena where protected GIs (PGIs) and festivals meet; (ii) specifying how CAW’s adaptive practices – translation, reorganization, and transformation – operate as mechanisms that generate recognition, legitimization, and valorization; and (iii) foregrounding festival publics, pedagogy, and experimentation as drivers of adaptation. Drawing on multi-sited ethnographic fieldwork in Norway at three apple-based PGI festivals and, for comparison, one non-PGI apple festival, we show how bottom-up festivalization recalibrates the top-down governance of GIs and yields both intended outcomes and unintended frictions. By shifting analysis from stage models to patterned work on living heritage, the CAW-in-GI-festivals approach makes adaptation practices visible and comparable across cases. In turn, it clarifies food heritagization’s internal dynamics and offers a lens on agri-food domains where de jure certification regimes intersect with de facto experiential publics.

Mange arkitekter og byggherrer velger i dag umalt trekledning fordi den krever mindre vedlikehold og får et naturlig uttrykk over tid. Men hva synes folk flest om den grå overflaten som utvikler seg når treverket står ute i vær og vind? En ny studie fra Norge, Sverige og Tyskland viser at flertallet av befolkningen fortsatt foretrekker malt trekledning. Samtidig er det store forskjeller mellom landene når det gjelder hvor godt folk aksepterer at treverket gråner naturlig. Resultatene tyder på at både kultur, erfaring og personlighet påvirker hvordan vi vurderer utseendet på trekledning.

Å velge trekledning handler om mer enn bare tekniske egenskaper. Utseende, vedlikeholds behov, kostnader og personlige preferanser spiller også en viktig rolle. En ny studie fra Norge, Sverige og Tyskland viser at bare én av fem foretrekker ubehandlet trekledning, og at både personlighet og lokale tradisjoner påvirker hva vi oppfatter som attraktive fasader. Med utgangspunkt i disse funnene har forskerne, som har utført studien, utviklet en enkel veiledning som kan hjelpe huseiere og byggherrer med å velge kledningsløsninger som passer deres forventninger til utseende, levetid og vedlikehold.

Hvor ofte folk vasker, maler og skifter ut trekledning varierer betydelig mellom land og mellom ulike brukergrupper. En spørreundersøkelse i Norge, Sverige og Tyskland viser at både erfaring, sosioøkonomiske forhold og personlighetstrekk påvirker hvor mye vedlikehold folk mener er nødvendig.

Norway spruce (Picea abies (L.) H. Karst.) is one of the most important tree species in Europe and Norway both ecologically and economically. To produce sufficient seedlings for reforestation and commercial forestry, Norway spruce plants are commonly cultivated in forest nurseries where conditions such as high plant density and humidity may increase susceptibility to pathogen infection. Meanwhile, increasing fungicide resistance and stricter regulations on fungicide use have created a need for alternative and more sustainable disease management strategies. One potential approach is defense priming with the use of methyl jasmonate (MeJA), a plant hormone associated with defense activation. The aim of this study was to investigate the effects of MeJA seed priming on defense-related and physiological responses in Norway spruce seedlings from different provenances. Seeds originating from Aremark, Inderøy and Kilen were treated with MeJA or water (control) prior to sowing. Effects of seed treatment were evaluated through analyses of germination, growth, stomatal characteristics, pigment composition, relative gene expression and resistance to Botrytis cinerea. Relative gene expression of selected defense-related (PaCHI4, PaPAL2, PaTPS-CAR) and photosynthesis-related (PaPSI, PaPSII, PaCHL) genes were quantified using RT-qPCR following mechanical wounding. MeJA treatment significantly reduced seedling growth across provenances and was associated with lower germination in several treatments, suggesting physiological trade-offs related to defense activation. MeJA treatment also affected expression of both defense- and photosynthesis-related genes, including increased expression of PaCHI4 and PaPAL2, as well as altered expression of PaPSI and PaPSII, indicating that seed priming affected both defense and photosynthetic physiology. Mechanical wounding further amplified several of these responses and strongly affected pigment composition and gene expression. Chlorophyll a concentration and chlorophyll a/b ratios were reduced following wounding and MeJA treatment, while carotenoid response varied among provenances. In contrast, stomatal size was not significantly affected by treatment. Following B. cinerea inoculation, MeJA-treated seedlings generally exhibited a tendency toward higher resistance compared to controls, although responses varied among provenances and were not consistently significant. Overall, the results demonstrate that MeJA seed priming influences multiple physiological and molecular processes in Norway spruce seedlings and may enhance inducible defense responses against pathogen stress.

Due to rising concerns over the negative effects from pesticides, nations like Norway have implemented integrated pest management (IPM) in their national strategy to reduce pesticide use. IPM highlights semi-natural habitats (SNH) as key elements in conservation biological control, as they provide essential resources for natural enemies. One of the pests in apple orchards is the codling moth (Tortricidae: Cydia pomonella) and it is known to have developed resistance against a variety of pesticides. The codling moth may be exposed to ground dwelling predators such as carabid beetles (Coleoptera: Carabidae) and spiders (Arachnida: Araneae) during its life stages on the orchard floor. The aim of this study was to explore how semi-natural habitats (SNH) influence ground dwelling predator communities in apple orchards and its possible impacts for biocontrol using the codling moth as an example. By using pitfall traps, this study explored how predator communities varied across a distance gradient from adjacent SNH in three apple orchards in Østfold, Norway throughout one growth season. Results suggest that activity-density, species diversity and richness are influenced by season rather than distance. Carabid communities were found to become less functionally diverse towards the orchard interior as both functional diversity indices decreased with increasing distance.
