Abstract Energy-efficient lighting solutions, while beneficial for reducing energy consumption, also pose challenges in terms of light pollution. Light pollution, defined as excessive or misdirected artificial light, has become a significant environmental issue globally. This perspective paper explores the extent, effects, and knowledge gaps related to light pollution, with a focus on its impact on human health, ecosystems, and energy consumption. This study focuses on Norway, a country that is particularly relevant for studying light pollution due to its far northern location. At high latitudes, the variation in natural light is larger over the year than at lower latitudes. Therefore, a Nordic perspective is valuable to present knowledge about effects of artificial lighting under these conditions. Under the midnight sun, minimal additional outdoor lighting is required, whereas during the winter season, outdoor lighting may be utilised continuously. The paper synthesizes findings from various studies, highlighting the rapid increase in light pollution due to urbanisation, infrastructure development, and the widespread adoption of LED technology. Human health effects include alterations of circadian rhythms, increased risk of accidents, and potential links to serious diseases such as cancer. Ecosystem impacts are profound, affecting a number of species i.e., within insects and bats, and may lead to for instance disturbances in navigation and circadian rhythms, habitat fragmentation, and altered predator–prey dynamics. This article identifies significant knowledge gaps, particularly in the measurement of light pollution, understanding its health effects, and its impact on various species. Recommendations for future research and policy development are provided, emphasising the need for interdisciplinary approaches to mitigate the adverse effects of light pollution and promote sustainable lighting practices.

ABSTRACT Increasing drought frequency and intensity affect biophysical functions of natural ecosystems. In tropical semi‐arid savannas, while immediate drought effects are well‐studied, the drought legacy effects on vegetation composition and associated ecosystem functions remain unclear. We used data of vegetation composition, net ecosystem CO 2 exchange, surface albedo and evapotranspiration (ET) in 2017–2022 from a savanna ecosystem, Southwest China, to investigate the legacy effect of an extreme drought event that occurred in 2019. Vegetation declined continuously for 3 post‐drought years. While tree numbers declined by 12%, shrub numbers dropped by 50% compared with pre‐drought levels, shifting vegetation dominance toward trees. This structural change caused sustained reductions in albedo and ET, which remained below pre‐drought levels, despite gross primary production recovering in the years immediately post‐drought. Vegetation shifts disproportionately impact ecosystem functions, with energy and water fluxes exhibiting greater vulnerability and potentially enhancing regional warming as droughts increase in Asian savannas.

Debatten om fôrtilsetjingsstoffet Bovaer har vore høgrøysta det siste året. Nokon har sett verdskonspirasjonar i mjølkeglaset, andre har svara med å stable vitskaplege rapportar i høgda og erklært at det var prov nok til å avslutte saka.

Nord-Norge har svært gode beiteressurser og en stor uutnyttet beitekapasitet, men store utfordringer med nedgang i antall beitedyr og utmarksbeitebønder. Manglende rekruttering, motivasjon og økonomiske utfordringer er pekt på som årsaker til nedgangen. Teknologi som sporingsbjeller, virtuelle gjerder og droner er verktøy som utmarksbeitebonden kan ha stor nytte av/Northern Norway has high quality grazing resources and large, unused grazing capacity, yet faces major challenges due to a decline in the number of grazing animals and rangeland farmers. Lack of recruitment, motivation, and economic difficulties have been identified as reasons for this decline. Technologies such as tracking collars, virtual fencing, and drones are tools that can be highly beneficial for rangeland farmers.

The soil-borne oomycete Phytophthora cactorum causes crown rot, a major disease of the allo-octoploid strawberry (Fragaria × ananassa Duch., 2n = 8× = 56) that limits cultivation worldwide. Resistance to P. cactorum is a highly desirable trait but is typically quantitative and moderately heritable. A better understanding of the genetic basis of resistance to crown rot is essential for developing durable crown rot-resistant cultivars. We conducted a genome-wide association study (GWAS) using multi-locus models on 100 wild strawberry accessions from South and North America. The accessions were genotyped using the Axiom™ 50 K strawberry SNP array and mapped to the F. × ananassa cv. Royal Royce v. 1.0 reference genome. Testing for resistance to P. cactorum revealed a wide range of phenotypes. A single genetic marker, AX-184528282, located on chromosome 7B, was strongly associated with resistance to P. cactorum and explained 53% of the observed phenotypic variation. This marker was present in several highly resistant exotic Fragaria accessions that represent potential donors for introgression of favorable alleles into modern strawberry cultivars. In addition, several strong candidate resistance genes were identified within the 2 Mb genomic region surrounding the significant marker. This study advances understanding of resistance to P. cactorum in strawberry and identifies genetic resources that can accelerate the development of crown rot-resistant cultivars through marker-assisted breeding.

Verdiprøving av fôrvekster er en forvaltningsoppgave som NIBIO gjennomfører på oppdrag fra og etter retningslinjer gitt av Mattilsynet (www.mattilsynet.no). Målet er å framskaffe resultater for godkjenning av nye sorter for opptak på offisiell norsk sortsliste. Prøvingen er en kontinuerlig, ikke tidsavgrenset prøving. Flerårige arter legges ut tre ganger med tre registrerings- og høsteår etter hvert utlegg. Artene blir som hovedregel prøvd i fem distrikter: Østlandet, Fjellbygdene, Vestlandet, Midt-Norge og Nord-Norge. I 2025 var det kandidatsorter av artene engsvingel/raisvingel, Westerwoldsk raigras og Italiensk raigras som var ferdig testet. I alt seks sorter var ferdig testet, hvor en sort av engsvingel, en av raisvingel, en av Italiensk raigras og en av Westerwoldsk raigras ble anbefalt godkjent.
