      Alien species form one of the main threats to global biodiversity. Although Life Cycle Assessment attempts to holistically assess environmental impacts of products and services across value chains, ecological impacts of the introduction of alien species are so far not assessed in Life Cycle Impact Assessment. Here, we developed country-to-country-specific characterization factors, expressed as the ...
    • What is the true influence of the red tide on the production, price and marketing of the Galician mussel? 

      Martínez, Pablo Louzao (Master thesis; Mastergradsoppgave, 2017-08-14)
      In recent years, the Galician mussel industry has encountered an environmental factor capable of influencing its sea farming; the red tide. Its environmental and economic impact on mussel aquaculture is directly related to the duration of toxic processes. Therefore, in this work will be used the number of days of closure of production areas in order to analyze what is the true influence that red ...

Little empirical research has been done on pricing strategies and demand ...
    • What we do in the dark: Prevalence of omnivorous feeding activity in Arctic zooplankton during polar night 

      Kunisch, Erin; Graeve, Martin; Gradinger, Rolf Rudolf; Flores, Hauke; Varpe, Øystein; Bluhm, Bodil (Journal article; Tidsskriftartikkel, 2023-07-04)
      During the productive polar day, zooplankton and sea-ice amphipods fulfill a critical role in energy transfer from primary producers to higher trophic-level species in Arctic marine ecosystems. Recent polar night studies on zooplankton and sea-ice amphipods suggest higher levels of biological activity than previously assumed. However, it is unknown if these invertebrates maintain polar night activity ...

    • When spring ephemerals fail to meet pollinators: Mechanism of phenological mismatch and its impact on plant reproduction 

      Kudo, Gaku; Cooper, Elisabeth J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-12)
      The flowering phenology of early-blooming plants is largely determined by snowmelt timing in high-latitude and high-altitude ecosystems. When the synchrony of flowering and pollinator emergence is disturbed by climate change, seed production may be restricted due to insufficient pollination success. We revealed the mechanism of phenological mismatch between a spring ephemeral (<i>Corydalis ambigua</i>) ...
    • When the brain goes diving: transcriptome analysis reveals a reduced aerobic energy metabolism and increased stress proteins in the seal brain 

      Fabrizius, Andrej; Hoff, Mariana Leivas Müller; Engler, Gerhard; Folkow, Lars; Burmester, Thorsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-09)
      <b>Background: </b>During long dives, the brain of whales and seals experiences a reduced supply of oxygen (hypoxia). The brain neurons of the hooded seal (Cystophora cristata) are more tolerant towards low-oxygen conditions than those of mice, and also better survive other hypoxia-related stress conditions like a reduction in glucose supply and high concentrations of lactate. Little is known ...
    • When to stop searching in a highly uncertain world? A theoretical and experimental investigation of “two-way” sequential search tasks 

      Bouhlel, Imen; Chessa, Michela; Festre, Agnes Monique Marie; Guerci, Eric (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-13)
      When to stop exploring is crucial in contexts where learning to manage time and uncertainty is critical for carrying out successful initiatives (e.g., innovation, personnel recruitment, vaccine discovery). We investigate analytically and experimentally the exploration-exploitation trade-offs in such contexts. A “two-way” sequential search task is proposed, where the classical exploration-exploitation ...

    • Where do the treeless tundra areas of northern highlands fit in the global biome system: toward an ecologically natural subdivision of the tundra biome 

      Virtanen, Risto; Oksanen, Lauri Kalervo; Oksanen, Tarja Maarit; Cohen, Juval; Forbes, Bruce C.; Johansen, Bernt; Käyhkö, Jukka; Olofsson, Johan; Pulliainen, Jouni; Tømmervik, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-15)
      According to some treatises, arctic and alpine sub-biomes are ecologically similar, whereas others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands fall outside of the two recent subdivisions of the tundra biome. We seek an ecologically natural resolution to this long-standing and far-reaching problem. We studied broad-scale patterns in climate and ...
    • Whirly proteins as communicators between plant organelles and the nucleus? 

      Krause, Kirsten; Herrmann, Ullrich; Fuss, Janina; Miao, Ying; Krupinska, Karin (Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
      Whirly proteins belong to a small family of proteins with a characteristic secondary structure and a conserved DNA binding domain that is found mainly in angiosperms. At least one member of the Whirly protein family, Whirly1, is dually targeted to the nucleus and to the chloroplasts and it was shown that apart from its initially described function as a transcriptional regulator of nuclear disease ...

      Current seaweed consumption and attitudes and preferences toward seaweed food products in a Western society are investigated to inform the seaweed industry regarding product development and marketing strategies. A national survey of 521 Australian consumers was conducted. About 75% of respondents had eaten seaweed; however, only 37% had consumed seaweed regularly over the past 12 months. Key drivers ...
    • Who's at risk in the backcountry? Effects of individual characteristics on hypothetical terrain choices 

      Mannberg, Andrea; Hendrikx, Jordy; Landrø, Markus; Ahrland Stefan, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-18)
      We use data from an online survey in Norway (N = 467, 73% male; age: M = 34, SD = 10.07) to analyze hypothetical choices in hazardous avalanche terrain. We further analyze differences in stated preference for and willingness to accept to ski relatively risky terrain. Our results suggest that risk attitudes and perception constitute important determinants for hypothetical terrain choices. We further ...
    • Whole genome sequencing reveals development of structured salmon lice (Lepeophtheirus salmonis, Krøyer, 1838) populations among aquaculture net pens through production 

      Brække, Nora (Master thesis; Mastergradsoppgave, 2023-05-15)
      Salmon louse, (Lepeophtheirus salmonis, Krøyer, 1838), is an ectoparasite that causes multiple health and economic problems in the farming of Atlantic salmon (Salmo salar L.), but also threatens wild salmonid species. The industry is struggling to identify proper measures for limiting lice infections, and to identify effective delousing treatments. One of the major production and management challenges, ...
    • Why and how to regulate Norwegian salmon production? – The history of Maximum Allowable Biomass (MAB) 

      Hersoug, Bjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-05)
      Salmon farming has been a great success story in Norway over the last 50 years, but the industry is still much disputed. Right from the start, farmers were licensed, with a limit on total production. In addition, each site was regulated according to carrying capacity. Over the years, various management measures have been used to regulate both the total production and environmental conditions, before ...
