SedaDNA reveals regional climate and bedrock nutrients as major drivers of terrestrial plant diversity in northern Fennoscandia.
Ocean-based economic development arising from an increasing interest in the ‘blue economy’ is placing ecosystems and small-scale fisheries under pressure. The dominant policy response for dealing with multiple uses allocation of coastal space through zone planning (CZP). Recent studies have shown that rush to develop blue economy regulate activity can result social injustices exclusion less powerful unrecognized groups (e.g., fishers, women, Indigenous peoples youth). To achieve a primary...
Mammalian herbivores shape the structure and function of many nutrient-limited or low-productive terrestrial ecosystems through modification plant communities plant–soil feedbacks. In tundra biome, mammalian may both accelerate decelerate biomass growth, microbial activity nutrient cycling, that is, ecosystem process rates. Selective foraging associated declines palatable species are known to be major drivers However, in dominant plants low palatability often linked with high herbivore...
Abstract Increased visitation to protected areas could have adverse impacts on the conservation values in areas, and therefore effective visitor monitoring methods are needed meet complex management challenges that arise. Collecting data human is highly time consuming, thus requiring more tools allow for high‐quality long‐term measurements. In this study, we show how unmanned aerial vehicles (i.e. UAV or drones) be used monitor tourism areas. Tourism has boomed national parks Norway recent...

Near-infrared spectroscopy (NIRS) is a high-throughput technology with potential to infer nitrogen (N), phosphorus (P) and carbon (C) content of all vascular plants based on empirical calibrations chemical analysis, but currently limited the sample populations upon which it based. Here we provide first step towards global arctic-alpine NIRS model foliar N, P C content. We found calibration models perform well (R2validation = 0.94 RMSEP 0.20% for R2validation 0.76 0.05% 0.82 1.16% C),...
Recreational trails are a vital element of protected natural areas (PNAs) infrastructure, which enables visitors to travel through and engage in various activities such as hiking, biking, horse riding. Degradation adversely affects the environment well safety comfort visitors. As role many PNAs is protect provide recreational opportunities, need obtain accurate information about condition direction their transformation evident. Spatial characteristics can be very heterogenic even within...
Silicon (Si) is one of the most common elements in earth bedrock, and its continental cycle strongly biologically controlled. Yet, research on biogeochemical Si ecosystems hampered by time cost associated with currently used chemical analysis methods. Here, we assessed suitability Near Infrared Reflectance Spectroscopy (NIRS) for measuring content plant tissues. NIR spectra depend characteristics present bonds between H N, C O, which can be calibrated against concentrations various...
Ruminant fodder production in agricultural lands latitudes above the Arctic Circle is constrained by short and hectic growing seasons with a 24-hour photoperiod low growth temperatures. The use of remote sensing to measure crop at high hindered intrinsic challenges, such as sun elevation angle coastal climate humidity, which influences spectral signatures sampled vegetation. We used portable spectrometer (ASD FieldSpec 3) assess spectra grass crops found that when applying multivariate...
Captive reindeer in German zoos and wildlife parks live outside their natural geographic range are exposed to a variety of viral, bacterial protozoan pathogens, some host-specific which they not native habitat. Reindeer blood samples ticks collected 2013 from 123 at 16 different zoological facilities were available previous study.

Abstract The effects of climate change on species richness is debated but can be informed by the past. Here, we assess impact Holocene changes and nutrients terrestrial plant across multiple sites from northern Fennoscandia using new sedimentary ancient DNA ( sed aDNA) data quality control methods. We find that increased steeply during rapidly warming Early Holocene. In contrast to findings most pollen studies, show continued increase through Middle Late even though temperature decreased,...
Background: Previous serological screenings have indicated that Eurasian semi-domesticated tundra reindeer (Rangifer tarandus tarandus) in Finnmark, Northern Norway, are exposed to alphaherpesvirus, gammaherpesvirus and pestivirus. Alphaherpesvirus (i.e., Cervid herpesvirus 2; CvHV2) has been identified as the transmissible component of infectious keratoconjunctivitis (IKC). Limited knowledge exists on presence prevalence virus infections other herding regions which hosting ~67,000 contact...
Tourism and nature-based recreation has changed dramatically during the COVID-19 pandemic. Travel restrictions caused sharp declines in visitation numbers, particularly remote areas, such as northern Norway. In addition, pandemic may have altered human-nature relationships by changing visitor behaviour preferences. We studied numbers Norway, based on user-generated data, form of photographic material that was uploaded to popular online platform Flickr. A total 195.200 photographs, taken...
Decision makers and stakeholders need high-quality data to manage ecosystem services (ES) efficiently. Landscape-level on ES that are of sufficient quality identify spatial tradeoffs, co-occurrence hotspots costly collect, it is therefore important increase the efficiency sampling primary data. We demonstrate how could be assessed more efficiently through image-based point intercept method determine tradeoff between number sample points (pins) used per image robustness measurements....
Complex interactions among multiple abiotic and biotic drivers result in rapid changes ecosystems worldwide. Predicting how specific can cause ripple effects potentially resulting abrupt shifts is of high relevance to policymakers, but difficult quantify using data from singular cases.

Hepatitis E virus (HEV) is a common cause of viral hepatitis in humans. In developing countries, HEV-infections seem to be mainly associated with pigs, but other animal species may involved transmission. Recently, anti-HEV antibodies were detected Norwegian wild reindeer. Here, we investigated seroprevalence semi-domesticated reindeer, animals closer contact humans than their counterparts. Blood samples (n = 516) obtained from eight reindeer herds during the period 2013-2017 and analysed...
