  • Pinto, Cecilia; Travers-Trolet, Morgane; Macdonald, Jed; Rivot, Etienne; Vermard, Youen (Canadian Science Publishing, 2019-08)
    The biological status of many commercially exploited fishes remains unknown, mostly due to a lack of data necessary for their assessment. Investigating the spatiotemporal dynamics of such species can lead to new insights into population processes and ...
  • Natugonza, Vianny (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-06-18)
    The advent of ecosystem-based fisheries management (EBFM) in recent years has expanded the scope of fisheries management, where policies are aimed not only at maximizing production (or biological yield) but also maintaining an optimal balance between ...
  • Kvaavik, Cecilia; Oskarsson, Gudmundur; Daníelsdóttir, Anna Kristín; Marteinsdottir, Gudrun (Public Library of Science (PLoS), 2019-12-30)
    Predator-prey relations, as well as the trophic ecology of highly migratory marine species, is important to understand their impact on the ecosystem. Conventional methods were used to study the diet composition and feeding strategy of the Northeast ...
  • Silva, Teresa Sofia Giesta da (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2018-12-14)
    Krill are an important component of the Icelandic marine ecosystem. Given their important ecological niche, as conveyors of biological production between phytoplankton and higher trophic levels, fluctuations in krill abundance can have large impacts ...
  • Malinauskaite, Laura; Cook, David; Davidsdottir, Brynhildur; Ögmundardóttir, Helga; Roman, Joe (Elsevier BV, 2019-04)
    The study presents the first systematic review of the existing literature on Arctic ES. Applying the Search, Appraisal, Synthesis and Analysis (SALSA) and snowballing methods and three selection criteria, 33 publications were sourced, including ...
  • Malinauskaite, Laura (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-06)
    The thesis examines the dynamics of Arctic social-ecological systems (SES) that enable human wellbeing benefits through whale ecosystem services (ES). It does so through a review of relevant literature, construction of conceptual models, two primary ...
  • Sturludottir, Erla; Desjardins, Christopher David; Elvarsson, Bjarki; Fulton, Elizabeth A.; Gorton, Rebecca; Logemann, Kai; Stefansson, Gunnar (Elsevier BV, 2018-11)
    Icelandic waters are very productive and the fisheries are economically important for the Icelandic nation. The importance of the fisheries has led to progressive fisheries management and extensive monitoring of the ecosystem. However, fisheries ...
  • Sturludottir, Erla (Departmento de Publicaciones del CSIC, 2018-12-20)
    Discarding fish has been a part of the fisheries for centuries but it has been very difficult to monitor how much is discarded, especially in areas where it is an illegal activity. In this study the ecological and economic effects of discarding were ...
  • Salazar, Alejandro; Rousk, Kathrin; Jónsdóttir, Ingibjörg Svala; Bellenger, Jean‐Philippe; Andrésson, Ólafur (Wiley, 2019-12-31)
    Warming can alter the biogeochemistry and ecology of soils. These alterations can be particularly large in high northern latitude ecosystems, which are experiencing the most intense warming globally. In this meta‐analysis, we investigated global trends ...
  • Oostdijk, Maartje (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-04-29)
    The management of marine resources pose a difficult commons problem as monitoring behavior is difficult and benefit flows from the resources are uncertain. Implementing individual transferable quota (ITQ) is a management regime in which quasi-property ...
  • Sigurdsson, Bjarni D.; Leblans, Niki; Dauwe, Steven; Guðmundsdóttir, Elín; Gundersen, Per; G. Gunnarsdóttir, Gunnhildur Eva; Holmstrup, Martin; Ilieva-Makulec, Krassimira; Kätterer, Thomas; Marteinsdóttir, Bryndís; Maljanen, Marja; Oddsdóttir, Edda Sigurdís; Ostonen, Ivika; Penuelas, Josep; Poeplau, Christopher; Richter, Andreas; Sigurðsson, Páll; van Bodegom, Peter; Wallander, Håkan; Weedon, James; Janssens, Ivan (Agricultural University of Iceland, 2016)
    This article describes how natural geothermal soil temperature gradients in Iceland have been used to study terrestrial ecosystem responses to soil warming. The experimental approach was evaluated at three study sites in southern Iceland; one grassland ...
  • Petursdottir, Thorunn (2020-06)
    Every summer, free-roaming sheep graze large parts of Icelandic rangeland ecosystems, even though some of these rangeland areas are estimated to be in a severely eroded or even collapsed ecological condition. Improved rangeland management and ecosystem ...
  • Ravolainen, Virve; Soininen, Eeva M.; Jónsdóttir, Ingibjörg Svala; Eischeid, Isabell; Forchhammer, Mads; van der Wal, René; Pedersen, Åshild Ø. (Springer Science and Business Media LLC, 2020-01-18)
    Vegetation change has consequences for terrestrial ecosystem structure and functioning and may involve climate feedbacks. Hence, when monitoring ecosystem states and changes thereof, the vegetation is often a primary monitoring target. Here, we summarize ...
  • Mutia, Thecla Munanie (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2016-09)
    Very little is known on the ecosystem impacts of emissions from geothermal power plants. The emissions, comprising mainly of non- condensable gases (NCGs) i.e. carbon dioxide, hydrogen sulphide, methane and trace elements such as arsenic, ...
  • Beck, Samantha V. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-01-30)
    Intraspecific variation in egg size and its effects on offspring fitness is well documented in fishes. Yet whether or not differential per propagule maternal investment (egg size) can influence phenotypic diversification is little understood. Arctic ...
