Fire ulike saltvassbaserte fiskeslam frå matfisk blei testa som gjødsel til eittårig raigras i eit potteforsøk i veksthus, og samanlikna med behandling utan gjødsel og planter tilførd mineralgjødsel. Alle typar slam vart doserte i ei mengde tilsvarande 3 kg fosfor/dekar. Gjødseleffekten til fosfor i fiskeslam var kring 45 % sammenliga med fosfor i mineralgjødsel for tre av fiskeslamslaga og 26 % for det fjerde. Fosforeffekten til fiskeslam var sannsynlegvis negativt påvirka av uønska høgt pH i jorblandinga brukt i forsøket. Nitrogen-effekten av fiskeslammet er estimert til å vera fråverande eller negativ. Bruk av fiskeslam gav ikkje problem med uynskte sporstoff inkludert salt eller andre giftige grunnstoff. Det er sannsynleg at me bør sjå på slammet som ei råvare til vidare foredling snarare enn eit fullt ferdig gjødselprodukt.

ASO er Norges første nasjonale, arealrepresentative overvåking av semi-naturlig eng, en truet naturtype med stort artsmangfold. I perioden 2021–2025 ble 713 enger registrert over hele landet. Estimert areal av seminaturlig eng er 2 200–4 500 km² (0,7–1,5 % av Norges landareal), betydelig mer enn tidligere kartlagt. 40 % av engene er intakte, men majoriteten er ikke i bruk og i ferd med å gro igjen. Problemarter og fremmede arter utgjør viktige påvirkningfaktorer, og 32 % av engene har fremmedartsinnslag. Artsmangfoldet er størst i slåttemark og naturbeitemark, og 35 rødlistede arter ble funnet. Rapporten gir anbefalinger for videre overvåking, inkludert justering av metoder, bedre datalagring og overgang til NiN 3.0. ASO gir viktig kunnskap for forvaltning og bevaring av semi-naturlig eng og dens artsmangfold i Norge.

Are ecological scaling relationships stable through time, or can shifting parameters signal “quiet” community reorganization before diversity loss becomes evident? Using a century-long resurvey of subalpine and alpine vegetation along an elevational gradient in Norway, we tested whether key scaling relationships linking (I) spatial extent to diversity, (II) elevational distance to compositional and functional dissimilarity, and (III) species commonness to occupancy have remained stable through time. In 2008 and 2022, we resurveyed semi-permanent plots in central Norway first sampled in 1923–1933 along 995–1495 m.a.s.l., aggregating plots into 50-m elevational belts. We quantified spatial scaling of diversity with area, community differences across elevation, and relationships linked to species commonness and occupancy. Scaling relationships revealed a reorganization that is not captured by richness alone. Large-scale community structuring across elevation remained remarkably stable over the past century, with largely unchanged species– area relationships, beta and zeta diversity, and abundance–occupancy relationships. Despite this, absolute dissimilarity across elevational belts declined with beta diversity increasingly driven by species turnover while the nestedness component weakened. Communities also became progressively characterised by more widespread, common species and a more even abundance distribution, in addition to a convergence of ecological preferences. While the elevational gradient has not collapsed into a uniform assemblage, key scaling parameters within the gradient have shifted. These changes suggest a gradual compositional and functional reorganization of the vegetation that might for now maintain ecosystem functioning through dominant generalists, while quietly eroding long-term ecosystem resilience through species losses.

This report presents results from apple cultivar testing at NIBIO Ullensvang during 2016–2024. In total, 23 cultivars and advanced selections were evaluated for flowering, harvest time, yield, tree efficiency, fruit quality, and potential storage performance. Clear differences were found among cultivars in productivity and market suitability. ‘Fonn’ and ‘Jonagold Decosta Robijn’ were the most promising cultivars, combining high and stable yields, good fruit quality, and attractive fruit size. Both of them can be recommended for further commercial testing in a wide scale. Cultivar ‘Santana’ showed value as a niche cultivar because of its stable yield, scab resistance, and suitability for low-allergen and organic production, although its relatively high acidity reduced taste scores. Small fruited cultivar ‘Early Crunch’ produces very tasteful fruits and may have potential in the snack-apple segment.

Boreal forests are important reservoirs of biodiversity, carbon and timber stocks. However, timber harvest can alter biodiversity in these forests without clear evidence on the duration needed for biotic groups to recover. Resilience of boreal forest biodiversity to clear-cut harvest was examined with a meta-analysis of 190 datasets from boreal and hemi-boreal forests of Europe/Russia and North America for arthropods, birds, small mammals, lichens, bryophytes and vascular plants. We modelled similarity of community composition between harvested and unharvested stands versus years post harvest. In approximately half of cases, predicted times for recovery to pre-harvest composition were ≤30 years. In other cases, recovery took much longer or had not occurred within the timeframe of our data; for example, in conifer forest: >100 years (bryophytes), >55 years (small mammals), ~95 years (lichens) and ~85 years (vascular plants). Saproxylic beetles showed no resilience within the 16 (conifer forest) or 29 (mixed forest) years post harvest for which we had data. Recovery generally took longer in conifer and mixed than in broadleaf forests, which always showed either resistance (bryophytes, vascular plants) or resilience with recovery within 12–25 years. Conserving biodiversity in boreal forests will require extended rotations, management for ‘old forest’ structural elements and areas protected from harvesting.

Anthropogenic land conversion is putting increasing pressure on wildlife populations around the world. To mitigate impacts, it is necessary to develop a detailed mechanistic understanding of how animals are affected by different types of human activity. A key challenge is to disentangle the effects of static infrastructure, like roads or buildings, and the presence of humans in the landscape. To address this question, we examined if terrestrial mammals altered their movement behaviour around buildings in response to reduced human mobility during COVID‐19 lockdowns. We compiled GPS tracking data from 35 study sites across five continents, for 10 carnivore species and 13 herbivore species, totalling >1 million location records from 586 individuals. For each study, we used integrated step selection analysis to test the extent to which animals changed their avoidance of buildings as lockdown took effect, leveraging the recently released Microsoft MLBuildings dataset of global building locations. Analysis of population‐level effects revealed that, in areas with high Human Footprint Index (HFI), animals tended to show a significant reduction in their avoidance of buildings during lockdown, but not in low HFI areas. No such trend was detected during equivalent periods in years other than 2020, indicating that behavioural changes were a result of reduced human mobility during lockdowns. Overall, our findings suggest that animals living alongside humans exhibit greater plasticity when people change their behaviour, likely indicating the combined effects of environmental filtering and habituation. More generally, our study provides a critical first step towards developing evidence‐based tools for forecasting how wildlife movement behaviour may change in response to different land‐use strategies, human activities, conservation interventions or environmental perturbations.
