    • Trading Off Tourism for Fisheries 

      Xuan, Bui Bich; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-22)
      This paper presents a deterministic bioeconomic model in which the creation of a marine protected area (MPA) is not only a fisheries management tool but also introduced in order to provide tourism amenity benefits. The theoretical model is illustrated with analysis of the Nha Trang Bay (NTB) MPA in Khanh Hoa province in Vietnam, where the anchovy purse seine fishery is considered. An amenity value ...
    • Impact of Multiple Ecological Stressors on a Sub-Arctic Ecosystem: No Interaction Between Extreme Winter Warming Events, Nitrogen Addition and Grazing 

      Bokhorst, Stef; Berg, Matty P.; Edvinsen, Guro Kristine; Ellers, Jacintha; Heitman, Amber; Jaakola, Laura; Mæhre, Hanne K; Phoenix, Gareth K.; Tømmervik, Hans; Bjerke, Jarle W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-30)
      Climate change is one of many ongoing human-induced environmental changes, but few studies consider interactive effects between multiple anthropogenic disturbances. In coastal sub-arctic heathland, we quantified the impact of a factorial design simulating extreme winter warming (WW) events (7 days at 6–7∘C) combined with episodic summer nitrogen (+N) depositions (5 kg N ha-1) on plant winter physiology, ...

      Thomas, Haydn J.D.; Myers-Smith, Isla H.; Bjorkman, Anne D.; Elmendorf, Sarah C.; Blok, Daan; Cornelissen, Johannes H. C.; Forbes, Bruce C.; Hollister, Robert D.; Normand, Signe; Prevéy, Janet S.; Rixen, C; Schaepman-Strub, G; Wilmking, M; Wipf, S; Cornwell, W; Kattge, J; Goetz, SJ; Guay, KC; Alatalo, JM; Anadon-Rosell, A; Angers-Blondin, S; Berner, LT; Björk, RG; Buchwal, A; Buras, A; Carbognani, M; Christie, K; Siegwart Collier, L; Cooper, Elisabeth J.; Eskelinen, A; Frei, ER; Grau, O; Grogan, P; Hallinger, M; Heijman, MMPD; Hermanutz, L; Hudson, JMG; Hulber, K; Iturrate-Garcia, M; Iversen, CM; Jaroszynska, Francesca Orinda Holl; Johnstone, JF; Kaarlejärvi, E; Kulonen, A; Lamarque, LJ; Lévesque, E; Little, CJ; Michelsen, A; Milbau, A; Nabe-Nielsen, J; Nielsen, SS; Ninot, JM; Oberbauer, SF; Olofsson, J; Onipchenko, VG; Petraglia, A; Rumpf, SB; Semenchuk, Philipp; Soudzilovskaia, NA; Spasojevic, MJ; Speed, James David Mervyn; Tape, KD; Te Beest, M; Tomaselli, M; Trant, A; Treier, UA; Venn, S; Vowles, T; Weijers, S; Zamin, T; Atkin, OK; Bahn, M; Blonder, B; Campetella, G; Cerabolini, BEL; Chapin III, FS; Dainese, M; de Vries, FT; Díaz, S; Green, W; Jackson, R; Manning, P; Niinemets, Ü; Ozinga, WA; Penuelas, J; Reich, PB; Schamp, B; Sheremetev, S; van Bodegom, Peter Michiel (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-16)
      <p><i>Aim - </i>Plant functional groups are widely used in community ecology and earth system modelling to describe trait variation within and across plant communities. However, this approach rests on the assumption that functional groups explain a large proportion of trait variation among species. We test whether four commonly used plant functional groups represent variation in six ecologically ...
    • What Determines the Purchase Intention of Liquid Milk during a Food Security Crisis? The Role of Perceived Trust, Knowledge, and Risk 

      Hoque, Mohammed Ziaul; Alam, Md Nurul (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-16)
      Until today, inadequate food supply, malnutrition, food adulteration, etc., are still the key concern in developing economies. In order to address these issues of food security crisis, and to stimulate a sustainable supply of liquid milk (LM), a consumer behavior model was created, in which consumers’ perceived knowledge, trust and risk were the major catalysts. To shed light on this context, the ...
    • Transforming conflicts from the bottom-up? Reflections on civil society efforts to empower marginalized fishers in postwar Sri Lanka 

      Scholtens, Joeri; Bavinck, Jan Maarten (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      We analyze the efforts of an international consortium of academics and activists to understand and address a transnational fisheries conflict in South Asia. The so-called REINCORPFISH project (2010–2016) focused on an asymmetrical conflict between trawler fishers from the Indian state of Tamil Nadu who frequently transgress into Sri Lankan waters and northern Sri Lankan fishers, whose livelihoods ...

      Bighead carps (<i>Aristichthys nobilis</i>) were divided into four groups with different feeding strategies: group A, nature live food only (fertiliser only, 200 g urea + 160 g ethylamine phosphate + 250 g Huangjintai bio-fertiliser); group B, nature live food + 1/2 formulated feed; group C, nature live food + formulated feed; and group D, formulated feed only. The intestinal microbiomes of the ...
    • Do mothers also "manipulate" grandparental care? 

      Busch, Mari Veierud; Olaisen, Sandra; Bruksås, Ina Jeanette; Folstad, Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-15)
      Paternity uncertainty has proven to be a robust ultimate hypothesis for predicting the higher investment in grandchildren observed among maternal grandparents compared to that of the paternal grandparents. Yet the proximate mechanisms for generating such preferred biases in grandparental investment remain unclear. Here we address two different questions for better understanding the proximate mechanisms ...
    • Habitats and movement patterns of white whales Delphinapterus leucas in Svalbard, Norway in a changing climate

      <p><i>Purpose</i>: The purpose of this study was to investigate how a consumer’s intention to purchase a premium or luxury product influences the anticipated regret and guilt.</p> <p><i>Design/methodology/approach</i>: A 2 × 2 × 2 between-subjects design (label: premium versus luxury × prior event: success versus failure × product type: hedonic versus utilitarian) on guilt and regret was ...
    • Brucella spp. at the wildlife-livestock interface: An evolutionary trajectory through a livestock-to-wildlife "host jump"? 

      Godfroid, Jacques (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-18)
      Brucella infections in wildlife have gained a lot of interest from the scientific community and different stakeholders. These interests are often different and sometimes conflicting. As a result, different management perspectives and aims have been implemented (One Health, public health, veterinary public health, maintenance of a brucellosis free status in livestock, sustainable wildlife harvesting ...
    • Relationships between depth and δ15N of Arctic benthos vary among regions and trophic functional groups 

      Stasko, Ashley D; Bluhm, Bodil; Reist, James D; Swanson, Heidi; Power, Michael (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-03-27)
      Stable isotope ratios of nitrogen (δ<sup>15</sup>N) of benthic primary consumers are often significantly related to water depth. This relationship is commonly attributed to preferential uptake of <sup>14</sup>N from sinking particulate organic matter (POM) by microbes, and suggests that relationships between δ<sup>15</sup>N and water depth may be affected by local POM sources and flux dynamics. ...
    • Evidence for Strong Fixation Bias at 4-fold Degenerate Sites Across Genes in the Great Tit Genome 

      Gossmann, Toni Ingolf; Bockwoldt, Mathias; Diringer, Lilith; Schwarz, Friedrich; Schumann, Vic-Fabienne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-29)
      It is well established that GC content varies across the genome in many species and that GC biased gene conversion, one form of meiotic recombination, is likely to contribute to this heterogeneity. Bird genomes provide an extraordinary system to study the impact of GC biased gene conversion owed to their specific genomic features. They are characterized by a high karyotype conservation with ...
    • Effect of a quality-improving codend on size selectivity and catch patterns of cod in bottom trawl fishery 

      Brinkhof, Jesse; Herrmann, Bent; Larsen, Roger B.; Veiga-Malta, Tiago (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-26)
      A new codend concept developed and tested exhibited significantly improved quality of caught cod (<i>Gadus morhua</i>) compared to that of the conventional codend used in the Barents Sea bottom trawl fishery. However, the design of the new quality-improving codend raised concerns about its size selectivity and the possibility that higher retention probability could negatively impact the catch pattern ...
