    Hantering av forskningsdata vid Linnéuniversitetet2018Rapport (Annet vitenskapelig)
    Abstract [sv]

    Ett arbete för en övergång till ett öppet vetenskapssystem pågår både nationellt och inom EU. I Sverige är det Vetenskapsrådet som fått i uppdrag att ta fram riktlinjer för hur denna övergång ska genomföras, och målbilden är att ett sådant system ska vara på plats år 2025. Linnéuniversitetet har som myndighet ansvar att stödja sina anställda forskare vad gäller hantering av forskningsdata.

    För att få en bättre förståelse för hur forskningsdata hanteras vid lärosätet skickades en enkät ut till lärosätets forskare av gruppen som genomför en förstudie för inrättande av en Data Access Unit (DAU) vid Linnéuniversitetet. Gruppen består av personal från universitetsarkivet, universitetsbiblioteket, IT-avdelningen och Grants and Innovation Office. DAU kommer att stödja Linnéuniversitetets forskare i fråga om hantering, lagring, tillgängliggörande och bevarande av forskningsdata. Arbetet görs i samarbete med den nationella forsknings-infrastrukturen SND, Svensk Nationell Datatjänst

    Long-term succession in a Danish temperate deciduous forest2005Inngår i: Ecography, Vol. 28, nr 2, s. 157-164Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Forest successional trajectories covering the last 2000 yr from a mixed deciduous forest in Denmark show a gradual shift in dominance from Tilia cordata to Fagus sylvatica and a recent increase in total forest basal area since direct management ceased in 1948. The successions are reconstructed by combining a fifty-year record of direct tree observations with local pollen diagrams from Draved Forest, Denmark. Five of the seven successions record a heathland phase of Viking Age dating from 830 AD. The anthropogenic influence is considerable throughout the period of study even though Draved contains some of the most pristine forest stands in Denmark. Anthropogenic influence including felling masks the underlying natural dynamics, with the least disturbed sites showing the smallest compositional change. Some effects of former management, such as loss of Tilia cordata dominance, are irreversible. Artificial disturbance, particularly drainage, has accelerated and amplified the shift towards Fagus dominance that would have occurred on a smaller scale and at a slower rate in the absence of human intervention.

    Møter med Kina: norsk diplomati, næringsliv og misjon 1880-19372018Collection/Antologi (Fagfellevurdert)
    Abstract [no]

    Møter med Kina handler om møter mellom mennesker på tvers av geografiske, kulturelle og språklige grenser. Ukjent for de fleste, flyttet en rekke nordmenn til Kina mellom 1890 og 1937. Noen var misjonærer. Andre reiste for å drive handel eller arbeide i det kinesiske tollvesenet. For første gang samles historien til enkeltpersoner fra diplomati, næringsliv og misjon i en felles historie om norsk migrasjon til Kina. Boken formidler historisk analyse i fortellingens form. Her presenteres nye sider av kjente størrelser som general Munthe og misjonæren Marie Monsen. Ikke minst løftes nye og hittil ukjente historier fram. Ingeniør Skappel søkte å skape et globalt finansimperium gjennom en skandinavisk-kinesisk bank. Norges første Kina-misjonær Anna Jakobsen, trosset alt og alle for å gifte seg med Cheng Xiuqui. Gjennom fortellinger om mennesker som levde transnasjonale liv, hendelser som risopprøret i Changsha i 1910 og varer som medisintran, kaster boken nytt lys over hvordan enkeltindivid utnytter teknologiske nyvinninger og transnasjonale handlingsrom i håp om å nå nye mål. Noen lykkes. Andre ender i fallitt. Alle erfarer mer enn de kunne forestille seg. Slik gir boken ny kunnskap ikke bare om norsk migrasjon og norsk-kinesisk historie, men også om globalisering som historisk fenomen.

    Mainstreaming virtual mobility - helping teachers to get on board2018Inngår i: Telecollaboration and virtual exchange across disciplines : in service of social inclusion and global citizenship: Book of Abstracts, UNIcollaboration , 2018, s. 24-24Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Despite many innovative initiatives, virtual mobility is still a relatively unexploited aspect of internationalisation at European universities. An internal project at Linnaeus university, Global Classroom, has aimed to create a framework and organisation to establish international networking and online collaboration as key elements of all degree programmes. The project aimed to promote the concept of virtual mobility and inspire faculty to adopt it in their programmes. A self-evaluation tool was developed for use in workshops with degree programme coordinators. This tool helps them assess their programme’s present status of internationalisation and highlight potential development areas. Each programme team can then, in consultation with the project team, devise and implement an action plan in order to achieve these objectives. The project also developed a toolbox for digital collaboration and worked with other institutions to offer an online collaborative course for teachers in the art of online collaboration. Another important issue was to create incentives for teachers to work with virtual mobility, including the use of digital badges. This session aims to discuss how virtual mobility can be mainstreamed and what types of incentives are needed as a catalyst for development.

    Colour responses from wood, thermally modified in superheated steam and pressurized steam atmospheres2010Inngår i: Wood Material Science & Engineering, ISSN 1748-0272, E-ISSN 1748-0280, Vol. 5, nr 3, s. 211-219Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this study, two different methods were used to produce thermally modified wood. One was carried out in a typical kiln drying chamber using superheated steam (SS) and the other used pressurized steam in an autoclave cylinder (PS). Overall, both processes followed the same principles and the wood was not treated with any chemicals. Two wood species were studied, Scots pine (Pinus sylvestris) and Norway spruce (Picea abies). Treatments in the autoclave were carried out under pressure using temperatures of 160°C, 170°C and 180°C. Temperatures of 190°C and 212°C were used in treatments in the chamber at normal air pressure. The colour was measured using L*C*H colour space. Results for both species showed that similar L* (lightness) can be reached at lower (20-308C) temperatures using PS compared with SS treatment. The hue angle of PS-treated wood was smaller than that of SS-treated wood. No significant difference in C* (chroma) was detected. The difference in E value between PS- and SS-treated wood was smaller for Norway spruce than for Scots pine. The residual moisture content was about 10% higher in wood treated by the PS process compared with the SS process

    Punk, klass och karriär2013Inngår i: ARKIV. Tidskrift för samhällsanalys, ISSN 2000-6225, E-ISSN 2000-6217, Vol. 1, nr 1, s. 97-113Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [sv]

    Punken, musikstilen och ungdomsrörelsen som bröt fram under andra halvan av 1970-talet, är samtidigt både omskriven och svår att ringa in. Med sin undersökning av vad punken betytt som socialt sammanhang för dem som var med, lägger Per Dannefjord och Magnus Eriksson en pusselbit till vår förståelse av denna ökända ungdomskultur. I artikeln jämför de den sociala bakgrunden och den nuvarande klasspositionen för den första generationens punkare i Sverige, aktiva mellan 1978 och 1982. Tvärtemot vad olyckskorpar under ”punkeran” trodde, visar det sig att punkarna lyckats bättre vad gäller både utbildningsnivå och social position jämfört med sin generation som helhet. Dannefjord och Eriksson ger två förklaringar till framgången: dels att punkens socialt brokiga sammansättning skapade en miljö där nya möjligheter blev synliga för framför allt ungdomar med arbetarbakgrund; dels att punken erbjöd läroprocesser som gav resurser som kunde utnyttjas i yrkes- och utbildningskarriärer inom framför allt kultursektorn.

    Quantifying disturbance effects on vegetation carbon pools in mountain forests based on historical data2009Inngår i: Regional Environmental Change, ISSN 1436-3798, E-ISSN 1436-378X, Vol. 9, nr 2, s. 121-130Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Although the terrestrial carbon budget is of key importance for atmospheric CO(2) concentrations, little is known on the effects of management and natural disturbances on historical carbon stocks at the regional scale. We reconstruct the dynamics of vegetation carbon stocks and flows in forests across the past 100 years for a valley in the eastern Swiss Prealps using quantitative and qualitative information from forest management plans. The excellent quality of the historical information makes it possible to link dynamics in growing stocks with high-resolution time series for natural and anthropogenic disturbances. The results of the historical reconstruction are compared with modelled potential natural vegetation. Forest carbon stock at the beginning of the twentieth century was substantially reduced compared to natural conditions as a result of large scale clearcutting lasting until the late nineteenth century. Recovery of the forests from this unsustainable exploitation and systematic forest management were the main drivers of a strong carbon accumulation during almost the entire twentieth century. In the 1990s two major storm events and subsequent bark beetle infestations significantly reduced stocks back to the levels of the mid-twentieth century. The future potential for further carbon accumulation was found to be strongly limited, as the potential for further forest expansion in this valley is low and forest properties seem to approach equilibrium with the natural disturbance regime. We conclude that consistent long-term observations of carbon stocks and their changes provide rich information on the historical range of variability of forest ecosystems. Such historical information improves our ability to assess future changes in carbon stocks. Further, the information is vital for better parameterization and initialization of dynamic regional scale vegetation models and it provides important background for appropriate management decisions.

    Influence of changed vegetations fields on regional climate simulations in the Barents Sea Region2008Inngår i: Climatic Change, ISSN 0165-0009, E-ISSN 1573-1480, Vol. 87, nr 1-2, s. 35-50Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In the context of the EU-Project BALANCE (http://balance-eu.info) the regional climate model REMO was used for extensive calculations of the Barents Sea climate to investigate the vulnerability of this region to climate change. The regional climate model REMO simulated the climate change of the Barents Sea Region between 1961 and 2100 (Control and Climate Change run, CCC-Run). REMO on similar to 50 km horizontal resolution was driven by the transient ECHAM4/OPYC3 IPCC SRES B2 scenario. The output of the CCC-Run was applied to drive the dynamic vegetation model LPJ-GUESS. The results of the vegetation model were used to repeat the CCC-Run with dynamic vegetation fields. The feedback effect of the modified vegetation on the climate change signal is investigated and discussed with focus on precipitation, temperature and snow cover. The effect of the offline coupled vegetation feedback run is much lower than the greenhouse gas effect.

    Forty years of natural dynamics in Swiss beech forests: Structure, composition, and the influence of former management2009Inngår i: Ecological Applications, Vol. 19, nr 7, s. 1920-1934Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We investigated forest development after the cessation of management based on inventory data from six beech forest reserves in Switzerland covering nearly 40 years, using observed changes to assess the textbook understanding of natural beech forest dynamics. Specifically, we evaluated the importance of light as a driver of tree species composition, and we aimed to disentangle the role of site characteristics and past management regimes for shaping today’s forest properties. Forest dynamics in the reserves showed a clear trend toward a broadening of the diameter distribution, an increase in basal area and standing dead wood, an increase in beech dominance, and a reduction of tree species diversity over time, conforming to expectations. However, the expected development of specific structural features, such as significant amounts of large living trees and snags or a small-scale mosaic of various developmental phases, appears to take longer than the time elapsed since the cessation of management. The observed loss in species richness can be attributed to decreasing light availability, as almost all species that disappeared were shade intolerant. Additionally, the shade-intolerant tree species had a characteristic bell-shaped diameter distribution in all reserves, indicating a lack of recruits, whereas shade-tolerant species had an irregular to monotonically decreasing diameter distribution, demonstrating sustained regeneration. Along the environmental gradient covered by the six reserves, abiotic factors are sufficient to explain tree species distribution, with management history not contributing additional information. This suggests that at larger scales, tree species composition is determined by abiotic factors, but historical management strategies were obviously adapted well to the species’ autecological requirements. Analyses such as ours provide the foundation for refining forest management systems as well as for developing effective and target-oriented conservation strategies. © 2009 by the Ecological Society of America beech forests;.

    Successional pathways in Swiss mountain forest reserves2012Inngår i: European Journal of Forest Research, ISSN 1612-4669, E-ISSN 1612-4677, Vol. 131, nr 2, s. 503-518Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Knowledge on the natural dynamics of Norway spruce-European silver fir forests is scarce, but is of high importance for the sustainable management of these ecosystems. Using a unique data set from five forest reserves in the Swiss Alps that covers up to 35 years, we elucidated communalities and differences in stand structure and species composition across the reserves and over time and investigated the role of site conditions versus intrinsic forest dynamics. For the early and late successional phases, we found a clear relationship between stand structure (diameter distributions) and species composition. Two pathways of early succession were evident as a function of the disturbance regime. Thus, the spatial extent of disturbances in spruce-fir forests strongly determines the pathway in early succession. Contrary to earlier descriptions of clearly distinguishable optima phases, our data did not reveal a relationship between stand structure and species composition for the early, mid-, and late optimum phases. Although the reserves investigated here are characterized by highly different climatic and soil conditions, their temporal development was found to fit well into a single successional scheme, suggesting that in spruce-fir mountain forests, the life-history strategies of the tree species may have a stronger influence on successional trajectories than site conditions per se.

    Abstract [sv]

    Forskare och forskning bedöms hela tiden. Det kan handla om huruvida en artikel ska bli publicerad i en viss tidskrift eller om en forskare ska tilldelas anslag eller inte. Ofta är det forskare som bedömer kollegor, så kallad peer-review. Forskning som nyligen publicerades i den nät­baserade vetenskapliga tidskriften PLOS Biology visar, dessvärre, att forskare är ganska dåliga på att ­bedöma vad som är betydelsefull forskning.

    Black Hawk-Down: Adaptation and the Military-Entertainment Complex2017Inngår i: Culture Unbound. Journal of Current Cultural Research, ISSN 2000-1525, E-ISSN 2000-1525, Vol. 9, nr 3, s. 365-389Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article investigates the non-fiction book Black Hawk Down (1999) by Mark Bowden, Black Hawk Down the movie (2001) directed by Ridley Scott, and the computer game Delta Force: Black Hawk Down (2003). The article suggests that while the movie and the game must be studied as adaptations of the first text, the tools developed by adaptation studies, and that are typically used to study the transfer of narratives from one media form to another, do not suffice to fully describe the ways in which these narratives change between iterations. To provide a more complete account of these adaptations, the article therefore also considers the shifting political climate of the 9/11 era, the expectations from different audiences and industries, and, in particular, the role that what James Der Derian has termed the Military-Industrial-Media-Entertainment Network (MIME-Net) plays in the production of narrative. The article thus investigates how a specific political climate and MIME-Net help to produce certain adaptations. Based on this investigation, the article argues that MIME-Net plays a very important role in the adaptation of the Black Hawk Down story by directing attention away from historical specificity and nuance, towards the spectacle of war. Thus, in Black Hawk Down the movie and in Delta Force: Black Hawk Down, authenticity is understood as residing in the spectacular rendering of carnage rather than in historical facts. The article concludes that scholarly investigations of the adaptation of military narratives should combine traditional adaptation studies tools with theory and method that highlight the role that politics and complexes such as MIME-Net play within the culture industry.

    Environmental values as a motivation of cycle tourism2018Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    The increasing popularity of cycling activities and events, and the need to encourage cycling to reduce tourism greenhouse gas (GHG) emission, require a better understanding of the motivations of cycle tourists. Cycle tourism is one kind of green sustainable tourism. While numbers of aspects of cycle tourism have been identified in previous studies, environmental values might be one of the factors to determine cycle tourism choice. Most findings show that personal factors are the main reason of cycling activity while environmental values play merely little role in the cycle tourism. This thesis project is aimed to study the motivations of non-club recreational cycle tourists in Kalmar, Sweden and the role of environmental values as a motivation of cycle tourism behavior. Qualitative exploration method has been adopted and 13 local cycle tourists have been interviewed for the project. By applying the environmental values framework, this thesis links two main factors of environmental values to the cycle tourism behavior, that is closeness to nature and environmental concern. The findings show that environmental values are good predictor of cycle tourism behavior. The role of environmental values as a motivation of cycle tourism is improving though still not the main motivation. More explicit attention to environmental related knowledge education may inform the operationalization and promotion of local cycle tourism development. As modern people may attach importance to hedonic experience for their cycle tourism activities, further researches are needed to understand the relationship of hedonic consumption values and cycle tourism behaviors.

    Tree mortality in dynamic vegetation models - A key feature for accurately simulating forest properties2012Inngår i: Ecological Modelling, ISSN 0304-3800, E-ISSN 1872-7026, Vol. 243, s. 101-111Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Dynamic vegetation models are important tools in ecological research, but not all processes of vegetation dynamics are captured adequately. Tree mortality is often modeled as a function of growth efficiency and maximum age. However, empirical studies have shown for different species that slow-growing trees may become older than fast-growing trees, implying a correlation of mortality with growth rate and size rather than age. We used the ecosystem model LPJ-GUESS to compare the standard age-dependent mortality with two size-dependent mortality approaches. We found that all mortality approaches, when calibrated, yield a realistic pattern of growing stock and Plant Functional Type (PFT) distribution at five study sites in Switzerland. However, only the size-dependent approaches match a third pattern, i.e. the observed negative relationship between growth rate and longevity. As a consequence, trees are simulated to get older at higher than at lower altitudes/latitudes. In contrast, maximum tree ages do not change along these climatic gradients when the standard age-dependent mortality is used. As tree age and size determine forest structure, our more realistic mortality assumptions improved forest biomass estimation, but indicate a potential decline of carbon storage under climate change. We conclude that tree mortality should be modeled as a function of size rather than age. (C) 2012 Elsevier B.V. All rights reserved.

    Sensitivity of high-resolution Arctic regional climate model projections to different implementations of land surface processes2012Inngår i: Climatic Change, ISSN 0165-0009, E-ISSN 1573-1480, Vol. 111, nr 2, s. 197-214Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper discusses the effects of vegetation cover and soil parameters on the climate change projections of a regional climate model over the Arctic domain. Different setups of the land surface model of the regional climate model HIRHAM were realized to analyze differences in the atmospheric circulation caused by (1) the incorporation of freezing/thawing of soil moisture, (2) the consideration of top organic soil horizons typical for the Arctic and (3) a vegetation shift due to a changing climate. The largest direct thermal effect in 2 m air temperature was found for the vegetation shift, which ranged between -1.5 K and 3 K. The inclusion of a freeze/thaw scheme for soil moisture shows equally large sensitivities in spring over cool areas with high soil moisture content. Although the sensitivity signal in 2 m air temperature for the experiments differs in amplitude, all experiments show changes in mean sea level pressure (mslp) and geopotential height (z) throughout the troposphere of similar magnitude (mslp: -2 hPa to 1.5 hPa, z: -15 gpm to 5 gpm). This points to the importance of dynamical feedbacks within the atmosphere-land system. Land and soil processes have a distinct remote influence on large scale atmospheric circulation patterns in addition to their direct, regional effects. The assessment of induced uncertainties due to the changed implementations of land surface processes discussed in this study demonstrates the need to take all those processes for future Arctic climate projections into account, and demonstrates a clear need to include similar implementations in regional and global climate models.

    Titel:

    ”Aktierekommendationer i en ny tid – podcasts på den finansiella marknaden”

     

    Bakgrund & problem:

    Aktierekommendationer ges traditionellt ut av diverse banker och analyshus. En bias har observerats vilket är till nackdel för investerare. Podcasts är ett förhållandevis nytt fenomen som kan erbjuda aktierekommendationer. Eftersom denna form av media är ny, finns lite forskning kring dess roll och potential för att erbjuda finansiella råd.

     

    Syfte:

    Uppsatsens syfte är att utvidga forskning kring podcasts och dess roll för marknadsfunktionen och marknadseffektiviteten

     

    Metod:

    En deduktiv utgångspunkt och ett kvantitativt förhållningssätt mellan teori och forskning tillämpas. En traditionell eventstudie med två olika tidsspann tillämpas för att studera aktierekommendationers påverkan på aktiekurser.

     

    Slutsats:

    Resultat pekar på att IH inte har stöd vid aktierekommendationer från podcasts vilket är ett tecken på stöd för EMH. Däremot har PPH stöd vilket i sin tur pekar på brister i EMH. Således är det ett tecken på att den svenska aktiemarknaden inte är fullt effektiv och den besitter inte semi-stark form. Inget informationsläckage kunde observeras i samband med rekommendationerna, något som skiljer sig från traditionella källor. Vi kunde visa på en viss temporär och positiv effekt gällande marknadsfunktionen för Small Cap. Genom en observerad ökad handelsvolym påvisar vi övertro på den svenska aktiemarknaden, något som gäller även för traditionella aktierekommendationer. Vi kan inte statistiskt säkerställa att kunskaps sprids mellan podcastlyssnare vilket skiljer sig mot teorier och tidigare forskning.

    Disturbance regimes at the interface of geomorphology and ecology2012Inngår i: Earth Surface Processes and Landforms, ISSN 0197-9337, E-ISSN 1096-9837, Vol. 37, nr 15, s. 1678-1682Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Geomorphological processes are an integral part of ecosystem functioning and ecosystem functioning affects geomorphological processes. Increasingly widespread acknowledgement of this simple idea is manifest in a vigorous research community engaged with questions that address the two-way interaction between biota and geomorphology, at a range of scales and in a variety of terrestrial and aquatic environments. Geomorphological disturbances are a core element of biogeomorphological interest, and although the disciplines of geomorphology and ecology have each developed languages and theories that help to explore, model and understand disturbance events, little attempt has been made to draw together these approaches. Following a brief review of these issues, we introduce thirteen papers that investigate the interactions and feedbacks between geomorphological disturbance regimes and ecosystem functions. These papers reveal the singularity of wildfire impacts, the importance of landsliding for carbon budgeting and of vegetation accumulation for landsliding, the zoogeomorphic role of iconic and Cinderella animals in fluvial geomorphology, biophysical interactions in aeolian, fluvial and torrential environments and the utility of living ecosystems as archives of geomorphic events. Most of these papers were first presented in a conference session at the European Geoscience Union General Assembly in 2010 and several others are from recent volumes of Earth Surface Processes and Landforms.

    Potential impact of climate change on ecosystems of the Barents Sea Region2008Inngår i: Climatic Change, ISSN 0165-0009, E-ISSN 1573-1480, Vol. 87, nr 1-2, s. 283-303Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The EU project BALANCE (Global Change Vulnerabilities in the Barents region: Linking Arctic Natural Resources, Climate Change and Economies) aims to assess vulnerability to climate change in the Barents Sea Region. As a prerequisite the potential impact of climate change on selected ecosystems of the study area has to be quantified, which is the subject of the present paper. A set of ecosystem models was run to generate baseline and future scenarios for 1990, 2020, 2050 and 2080. The models are based on data from the Regional Climate Model (REMO), driven by a GCM which in turn is forced by the IPCC-B2 scenario. The climate change is documented by means of the Koppen climate classification. Since the multitude of models requires the effect of climate change on individual terrestrial and marine systems to be integrated, the paper concentrates on a standardised visualisation of potential impacts by use of a Geographical Information System for the timeslices 2050 and 2080. The resulting maps show that both terrestrial and marine ecosystems of the Barents region will undergo significant changes until both 2050 and 2080.

    Peer-to-peer Teaching in Higher Education: A Critical Literature Review2016Inngår i: Mentoring & Tutoring, ISSN 1361-1267, E-ISSN 1469-9745, Vol. 24, nr 2, s. 124-136Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of my critical literature review is to identify studies where students are engaged as partners in teaching in higher education and to analyze how tutors and tutees benefit from peer teaching. Thirty studies were included for review. Thirteen countries are represented and two thirds of the studies conducted in the United States of America or the United Kingdom. There is a significant representation of studies from natural- and physical science. The dominating pedagogical belief and theory is social constructivism. The most frequent study design is the use of quasi-experimental pre- and post-testing. University teachers do not comprise the view of peer teaching necessarily resulting in greater academic achievement gains or deep learning. University teachers identify and esteem other pedagogical benefits such as improving students’: critical thinking, learning autonomy, motivation, collaborative and communicative skills. The main finding of this review is the clarification that the training of generic skills benefits from peer teaching. © 2016 Informa UK Limited, trading as Taylor & Francis Group.

    Industrial Validation of the Relationship between Color Parameters in Thermally Modified Spruce and Pine2016Inngår i: BioResources, ISSN 1930-2126, E-ISSN 1930-2126, Vol. 11, nr 1, s. 1369-1381Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Thermal modification causes the darkening of wood throughout its cross-section because of chemical changes in the wood. After treatment, naturally light wood species look darker or even tropical, depending predominantly on the treatment temperature and processing time. This study investigates the suitability of using color measurement to determine treatment intensity at the industrial scale. The color was determined using the L*, a*, and b* color space, also referred to as CIELab, and the relationship between lightness (L*) and the color parameters (a*) and (b*) was investigated for thermal modification treatments at 190 and 212 °C. The wood species studied were pine (Pinus sylvestris L.) and spruce (Picea abies L.). The results showed that yellowness (+b*) and redness (+a*) had a significant prediction ability for class treatments at 190 and 212 °C, respectively. After treatment, there were no noticeable differences in color between the species, but sapwood was darker than heartwood in both untreated and thermally modified wood. The thickness of the boards had a proportionally darkening effect on the color values.

    Satiation effects in piscivore prey size selection2006Inngår i: Ecology of Freshwater Fish, Vol. 15, nr 1, s. 78-85Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We present a functional response model that primarily evaluates effects of satiation in piscivore prey-size selection. The model also includes other passive processes, such as prey-size-dependent encounter rate and prey-size-dependent capture success, where capture success decreases and encounter rate increases with prey size. The model generates a wide variety of outcomes, where small, intermediate or large prey is positively selected for. These very different selectivity patterns are generated without any active prey choice included in the model. The results stress the importance of controlling for satiation and other passive processes in empirical studies on prey-size selection, especially if the aim is to test active prey choice in piscivores. © 2005 The Authors Journal compilation 2005 Blackwell Munksgaard.

    Determining the rate of change in a mixed deciduous forest monitored for 50 years2011Inngår i: Annals of Forest Science, ISSN 1286-4560, E-ISSN 1297-966X, Vol. 68, nr 3, s. 485-495Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Trees in two compartments of the mixed deciduous forest Draved Forest have been monitored regularly for 50 years. This data set was used to study the rate of change in forest structure and composition applying the Kolmogorov-Smirnov statistics, chi-square test for the goodness of fit, and principal component analysis. We also correlated the specific test statistics with other forest properties to elucidate the importance of various factors for the observed changes in forest structure. After 50 years, the still significant changes in the forest structure and species composition indicate that the compartments have not reached the state of an old growth forest. Although some measures indicated that the compartments were approaching this stage, other showed the opposite response and even an increasing rate of change. As the three statistical methods contributed in different ways, we recommend the combination of several statistical methods to assess changes in the forest structure.

    Estimating the potential impact of vegetation on the water cycle requires accurate soil water parameter estimation2011Inngår i: Ecological Modelling, ISSN 0304-3800, E-ISSN 1872-7026, Vol. 222, nr 15, s. 2595-2605Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It is well known that vegetation dynamics at the catchment scale depends on the prevailing weather and soil moisture conditions. Soil moisture, however, is not equally distributed in space due to differences in topography, weather patterns, soil properties and the type and amount of vegetation cover. To elucidate the complex interaction between vegetation and soil moisture, the dynamic vegetation model LPJ-GUESS (Smith et al., 2001), which provides estimations of vegetation dynamics, but does not consider lateral water fluxes was coupled with the hydrological TOPMODEL (cf. Beven, 2001) in order to be able to evaluate the importance of these lateral fluxes. The new model LG-TM was calibrated and validated in two climatically different mountain catchments. The estimations of runoff were good, when monthly and weekly time scales were considered, although the low flow periods at winter time were somewhat underestimated. The uncertainty in the climate induced change vegetation carbon storage caused by the uncertainty in soil parameters was up to 3–5 kg C m−2 (depending on elevation and catchment), compared to the total change in vegetation carbon storage of 5–9 kg C m−2. Therefore accurate estimates of the parameters influencing the water holding capacity of the soil, for example depth and porosity, are necessary when estimating future changes in vegetation carbon storage. Similarly, changes in plant transpiration due to climatic changes could be almost double as high (88 mm m−2) in the not calibrated model compared to the new model version (ca 50 mm m−2 transpiration change). The uncertainties in these soil properties were found to be more important than the lateral water exchange between grid cells, even in steep topography at least for the temporal and spatial resolution used here.

    Fifty year record of change in tree spatial patterns within a mixed deciduous forest2005Inngår i: Forest Ecology and Management, ISSN 0378-1127, E-ISSN 1872-7042, Vol. 215, nr 1-3, s. 212-223Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ripley's K-function was used to investigate the changes in spatial pattern among trees in a semi-natural mixed deciduous forest in Denmark over 50 years, from 1948 to 2001. Trees larger than 10 cm diameter in breast height (dbh) were mapped at 10-year intervals in 16 blocks within two former compartments. At the start of the observation, trees were found to be regularly distributed at distances less than 10 m. This pattern changed with time in different ways, depending on tree density at the beginning of the recording. Tree density has a greater influence on the number of recruits than on the number of dead trees. New recruits were significantly aggregated and positively correlated with dead trees, which suggests that regeneration occurred in canopy gaps. Compartments with many new recruits therefore showed a change in pattern towards more random distribution or even towards aggregation. In blocks with high basal area and few recruits, the pattern changed only slightly. Past management was found to be important in generating the patterns of tree distribution.

    Future changes in vegetation and ecosystem function of the Barents Region2008Inngår i: Climatic Change, ISSN 0165-0009, E-ISSN 1573-1480, Vol. 87, nr 1-2, s. 51-73Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The dynamic vegetation model (LPJ-GUESS) is used to project transient impacts of changes in climate on vegetation of the Barents Region. We incorporate additional plant functional types, i.e. shrubs and defined different types of open ground vegetation, to improve the representation of arctic vegetation in the global model. We use future climate projections as well as control climate data for 1981-2000 from a regional climate model (REMO) that assumes a development of atmospheric CO(2)-concentration according to the B2-SRES scenario [IPCC, Climate Change 2001: The scientific basis. Contribution working group I to the Third assessment report of the IPCC. Cambridge University Press, Cambridge (2001)]. The model showed a generally good fit with observed data, both qualitatively when model outputs were compared to vegetation maps and quantitatively when compared with observations of biomass, NPP and LAI. The main discrepancy between the model output and observed vegetation is the overestimation of forest abundance for the northern parts of the Kola Peninsula that cannot be explained by climatic factors alone. Over the next hundred years, the model predicted an increase in boreal needle leaved evergreen forest, as extensions northwards and upwards in mountain areas, and as an increase in biomass, NPP and LAI. The model also projected that shade-intolerant broadleaved summergreen trees will be found further north and higher up in the mountain areas. Surprisingly, shrublands will decrease in extent as they are replaced by forest at their southern margins and restricted to areas high up in the mountains and to areas in northern Russia. Open ground vegetation will largely disappear in the Scandinavian mountains. Also counter-intuitively, tundra will increase in abundance due to the occupation of previously unvegetated areas in the northern part of the Barents Region. Spring greening will occur earlier and LAI will increase. Consequently, albedo will decrease both in summer and winter time, particularly in the Scandinavian mountains (by up to 18%). Although this positive feedback to climate could be offset to some extent by increased CO(2) drawdown from vegetation, increasing soil respiration results in NEE close to zero, so we cannot conclude to what extent or whether the Barents Region will become a source or a sink of CO(2).

    Impact of non-outbreak insect damage on vegetation in northern Europe will be greater than expected during a changing climate2008Inngår i: Climatic Change, ISSN 0165-0009, E-ISSN 1573-1480, Vol. 87, nr 1-2, s. 91-106Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background insect herbivory, in addition to insect outbreaks, can have an important long term influence on the performance of tree species. Since a projected warmer climate may favour insect herbivores, we use a dynamic ecosystem model to investigate the impacts of background herbivory on vegetation growth and productivity, as well as distribution and associated changes in terrestrial ecosystems of northern Europe. We used the GUESS ecosystem modelling framework and a simple linear model for including the leaf area loss of Betula pubescens in relation to mean July temperature. We tested the sensitivity of the responses of the simulated ecosystems to different, but realistic, degrees of insect damage. Predicted temperature increases are likely to enhance the potential insect impacts on vegetation. The impacts are strongest in the eastern areas, where potential insect damage to B. pubescens can increase by 4-5%. The increase in insect damage to B. pubescens results in a reduction of total birch leaf area (LAI), total birch biomass and birch productivity (Net Primary Production). This effect is stronger than the insect damage to leaf area alone would suggest, due to its second order effect on the competition between tree species. The model’s demonstration that background herbivory may cause changes in vegetation structure suggests that insect damage, generally neglected by vegetation models, can change predictions of future forest composition. Carbon fluxes and albedo are only slightly influenced by background insect herbivory, indicating that background insect damage is of minor importance for estimating the feedback of terrestrial ecosystems to climate change.

    The relative importance of land use and climatic change in Alpine catchments2012Inngår i: Climatic Change, ISSN 0165-0009, E-ISSN 1573-1480, Vol. 111, nr 2, s. 279-300Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Carbon storage and catchment hydrology are influenced both by land use changes and climatic changes, but there are few studies addressing both responses under both driving forces. We investigated the relative importance of climate change vs. land use change for four Alpine catchments using the LPJ-GUESS model. Two scenarios of grassland management were calibrated based on the more detailed model PROGRASS. The simulations until 2100 show that only reforestation could lead to an increase of carbon storage under climatic change, whereby a cessation of carbon accumulation occurred in all catchments after 2050. The initial increase in carbon storage was attributable mainly to forest re-growth on abandoned land, whereas the stagnation and decline in the second half of the century was mainly driven by climate change. If land was used more intensively, i.e. as grassland, litter input to the soil decreased due to harvesting, resulting in a decline of soil carbon storage (1.2−2.9 kg C m–2) that was larger than the climate-induced change (0.8–1.4 kg C m−2). Land use change influenced transpiration both directly and in interaction with climate change. The response of forested catchments diverged with climatic change (11–40 mm increase in AET), reflecting the differences in forest age, topography and water holding capacity within and between catchments. For grass-dominated catchments, however, transpiration responded in a similar manner to climate change (light management: 23–32 mm AET decrease, heavy management: 29–44 mm AET decrease), likely because grassroots are concentrated in the uppermost soil layers. Both the water and the carbon cycle were more strongly influenced by land use compared to climatic changes, as land use had not only a direct effect on carbon storage and transpiration, but also an indirect effect by modifying the climate change response of transpiration and carbon flux in the catchments. For the carbon cycle, climate change led to a cessation of the catchment response (sink/source strength is limited), whereas for the water cycle, the effect of land use change remains evident throughout the simulation period (changes in evapotranspiration do not attenuate). Thus we conclude that management will have a large potential to influence the carbon and water cycle, which needs to be considered in management planning as well as in climate and hydrological modelling.

    Storm damage and long-term mortality in a semi-natural, temperate deciduous forest2004Inngår i: Forest Ecology and Management, ISSN 0378-1127, E-ISSN 1872-7042, Vol. 188, nr 1-3, s. 197-210Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    1. Wind-damaged trees, following the severe storm of 1999, are compared with data from a 50-year monitoring of Draved Forest, Denmark, to assess differing causes of mortality through time in an unmanaged semi-natural forest. Species-specific mortality characteristics and the changing effects of tree size and growth rate (diameter increment) on mortality through time are also investigated. 2. Storm was found to be the major mortality factor affecting large trees in this forest. For smaller trees, competition was an important cause of death, as trees that were found standing dead had a slower growth rate (diameter increment) than survivors. 3. Individual species showed different mortality patterns. Betula died more often and Fagus less often than expected from their abundance. Betula, Fagus and Tilia were mainly wind-thrown, whereas for Alnus and Fraxinus, 50% of the mortality was observed as standing dead trees. 4. Both wind and competition are important mortality factors in Draved Forest. (C) 2003 Elsevier B.V. All rights reserved.

    Variations in net ecosystem exchange of carbon dioxide in a boreal mire: Modeling mechanisms linked to water table position2007Inngår i: Journal of Geophysical Research, ISSN 0148-0227, E-ISSN 2156-2202, Vol. 112, nr G2Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    [1] In mires, which occupy large areas of the boreal region, net ecosystem CO2 exchange ( NEE) rates vary significantly over various timescales. In order to examine the effect of one of the most influencing variables, the water table depth, on NEE the general ecosystem model GUESS-ROMUL was modified to predict mire daily CO2 exchange rates. A simulation was conducted for a lawn, the most common microtopographical feature of boreal oligotrophic minerotrophic mires. The results were validated against eddy covariance CO2 flux measurements from Degero Stormyr, northern Sweden, obtained during the period 2001 - 2003. Both measurements and model simulations revealed that CO2 uptake was clearly controlled by interactions between water table depth and temperature. Maximum uptake occurred when the water table level was between 10 and 20 cm and the air temperature was above 15 degrees C. When the water table was higher, the CO2 uptake rate was lower, owing to reduced rates of photosynthetic carbon fixation. When the water table was lower, NEE decreased owing to the increased rate of decomposition of organic matter. When the water table level was between 10 and 20 cm, the NEE was quite stable and relatively insensitive to both changes within this range and any air temperature changes above + 15 degrees C. The optimal water table level range for NEE corresponds to that characteristic of mire lawn plant communities, indicating that the annual NEE will not change dramatically if climatic conditions remain within the optimal range for the current plant community.

    Potential impact of climate change and reindeer density on tundra indicator species in the Barents Sea region2008Inngår i: Climatic Change, ISSN 0165-0009, E-ISSN 1573-1480, Vol. 87, nr 1-2, s. 119-130Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Climate change is expected to alter the distribution of habitats and thus the distribution of species connected with these habitats in the terrestrial Barents Sea region. It was hypothesised that wild species connected with the tundra and open-land biome may be particularly at risk as forest area expands. Fourteen species of birds were identified as useful indicators for the biodiversity dependent upon this biome. By bringing together species distribution information with the LPJ-GUESS vegetation model, and with estimates of future wild and domestic reindeer density, potential impacts on these species between the present time and 2080 were assessed. Over this period there was a net loss of open land within the current breeding range of most bird species. Grazing reindeer were modelled as increasing the amount of open land retained for nine of the tundra bird species.
