  • 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 ...
  • 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 ...
  • 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 S.; 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 ...
  • 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 ...
  • Webert, Kyle C.; Herren, Cristina M.; Einarsson, Árni; Bartrons, Mireia; Hauptfleisch, Ulf; Ives, Anthony R. (Wiley-Blackwell, 2017-02)
    The importance of environmental disturbances as drivers of ecological communities depends not only on the magnitude of the disturbance, but also on the disturbance-specific sensitivity of the community. Organisms that alter the physical structure of ...
  • Murillo, F.J.; MacDonald, B.W.; Kenchington, E.; Campana, Steven; Sainte-Marie, B.; Sacau, M. (Informa UK Limited, 2018-02-15)
    We examined four species of sea pen (Anthoptilum grandiflorum, Halipteris finmarchica, Pennatula aculeata and Pennatula grandis) collected from the Gulf of St. Lawrence and mouth of the Laurentian Channel, eastern Canada. An exponential length–weight ...
  • Marteinsdóttir, Bryndís; Svavarsdóttir, Kristín; Þórhallsdóttir, Þóra Ellen (Wiley-Blackwell, 2017-12-07)
    Initial plant establishment is one of the most critical phases in ecosystem development, where an early suite of physical (environmental filtering), biological (seed limitation, species interactions) and stochastic factors may affect successional ...
  • Riege, Dennis A; Sigurgeirsson, Aðalsteinn (Agricultural University of Iceland, 2018)
    Afforestation in southwest Iceland is hindered by eroded, infertile soils and salt deposition from strong oceanic winds. A trial plot of 25 provenances of native downy birch collected throughout Iceland was established in 1998 near Keflavik International ...
  • Robinson, Sinikka I.; McLaughlin, Órla B.; Marteinsdóttir, Bryndís; O'Gorman, Eoin J. (Wiley, 2018-02-13)
    Global warming is predicted to significantly alter species physiology, biotic interactions and thus ecosystem functioning, as a consequence of coexisting species exhibiting a wide range of thermal sensitivities. There is, however, a dearth of research ...
