Høsten 2021, 2022 og 2023 ble det, i forbindelse med PROHØST-prosjektet, anlagt forsøk i høsthvete, med og uten gjødsling på høsten, med to såtider og med og uten sprøyting mot snømugg. I områder med stor sannsynlighet for varig snødekke, og derfor høy risiko for angrep av snømugg, ga fungicidbehandling rett før innvintring god beskyttelse mot snømugg. I disse feltene ble det observert over 50% redusert forekomst av snømugg i fungicidbehandla ruter. I felt som var angrepet av snømugg observerte vi dessuten avlingsøkning og redusert angrep av Microdochium spp. i korn fra fungicidbehandla ledd. Våre resultater viste at sprøyting med fungicid om høsten kan redusere forekomst av snømugg i høsthvete og videre bidra til økte avlinger og forbedret kornkvalitet. Dette gjaldt spesielt ved tidlig såing av høsthvete i innlandet, mens det ikke ble observert noe særlig skade forårsaket av snømugg-sopper i feltene anlagt i de mer sørlige områdene (Østfold/Vestfold).

Abstract Our understanding of how migratory wildlife populations affect incidence of infectious diseases spilling over into humans is limited. Ticks are expanding their distribution towards northern latitudes, causing emergence of tick‐borne diseases. Deer serve as reproduction hosts for adult ticks, supporting the tick populations. However, in northern areas, deer populations are partially migratory, and migrants occupy high elevation summer ranges that are unsuitable for ticks. Migration can thus theoretically lead to escape from exposure to ticks and to deer feeding fewer ticks, which lower disease hazard to humans. Combining data on Ixodes ricinus tick abundance with GPS‐tracking data of red deer ( Cervus elaphus ), we quantified the distributional overlap of ticks and red deer along elevational gradients in Norway. Furthermore, we correlated both deer density and the proportion of migratory deer with the incidence of Lyme disease in humans. We found that migratory deer summer ranges had colder climate and overlapped less with tick distribution than those of resident deer. Deer density consistently increased Lyme disease incidence in humans. However, we found only weak evidence that deer migration negatively affected Lyme disease incidence. Our study provides a rare quantification of how host availability, in terms of both host density and migratory movement, affects risk of a zoonotic disease.

A survey including 3112 responses from individual end users of wood cladding, from Norway, Sweden and Germany, was conducted with questions related to their experience and preferences regarding cladding with and without coatings. Based on these results and established scientific understanding of Service Life Prediction (SLP) of wood cladding, two decision trees were provided to guide end users in selecting a suitable material to meet their expectations when planning a new cladding. This approach makes the users reflect on maintenance requirements and aesthetic changes rather than choosing a product solely based on initial aesthetic appeal.

To optimise the use of renewable materials in construction, it is essential to understand the factors influencing decisions throughout their design and service life. Life Cycle Costing (LCC) supports sustainable development by aiming to minimise long-term costs through informed planning of service life, maintenance, and replacement. Central to this is the engineering concept of limit states - Ultimate Limit States (ULS) for structural safety and Serviceability Limit States (SLS) for functionality. However, in non-loadbearing applications such as cladding, maintenance is often driven by aesthetic deterioration rather than structural concerns. These aesthetic limit states are subjective and influenced by user preferences, personality traits, and cultural background. In practice, undesired aesthetic changes are among the main reasons for cladding replacement in Europe, alongside fungal decay and modernisation. Premature replacement due to insufficient communication about weathering effects and maintenance needs remains under-addressed. By accounting for variation in user preferences, material selection can be tailored to support a longer service life. This study presents multi-country variation in climate-related perceptions of wood and user preferences for wooden cladding.
