Guillermo; Gartzia, M; Soininen, E.M.; Christie, K.S.; Speed, J.D.M.; Ravolainen, V.T.; Forbes, B.C.; Gauthier, G.; Horstkotte, T.; Hoset, K.S.; Hoye, T.T.; Jónsdóttir, Ingibjörg Svala; Lévesque, E.; Mörsdorf, M.A.; Olofsson, J.; Wookey, P.A.; Hik, D.S. (John Wiley & Sons Ltd, 2016)
    Aim. Understanding the forces shaping biodiversity patterns, particularly for groups of organisms with key functional roles, will help predict ecosystem responses to environmental changes. Our aim was to evaluate the relative role of different drivers ...

    SOC has received increased attention over the last decades because of its role as an option to mitigate the effects of increased anthropogenic greenhouse gas emissions. In Iceland, the loss of vegetation and soil due to land-use and natural processes ...
  • Larranaga, Nicolas; Valdimarsson, S.K.; Linnansaari, T.; Steingrímsson, Stefán Óli (Wiley, 2018-02-28)
    Streams fluctuate in water flow because of natural (e.g., rain) and human‐induced events (e.g., hydropeaking). Magnitude, frequency, and predictability of these events can have drastic consequences for fish populations. We studied how rapid modifications ...

    Phenotypic differences between closely related taxa or populations can arise through genetic variation or be environmentally induced, leading to altered transcription of genes during development. Comparative developmental studies of closely related ...
  • Amri, Avianto; Bird, Deanne; Ronan, Kevin; Haynes, Katharine; Towers, Briony (Copernicus GmbH, 2017-04-24)
    This article investigates the implementation of disaster risk reduction education for children in Indonesia. In the last decade, education programmes related to this subject have been promoted as capable of reducing disaster losses and increasing ...

    This study aims to explain the distribution, maturity and population structure of Meganyctiphanes norvegica and Thysanoessa inermis in springtime in relation to main hydrographic regions around Iceland: Atlantic in the southwest, Atlantic-Arctic mixture ...
  • Soininen, E.M.; Barrio, Isabel C; Jepsen, J.U.; Ehrich, D.; Ravolainen, V.T.; Speed, J.D.M. (Springer Nature, 2018-09-27)
    Along with climate change, herbivory is considered a main driver of ecosystem change in terrestrial Arctic environments. Understanding how herbivory influences the resilience of Arctic ecosystems to ongoing environmental changes is essential to inform ...
  • Haynes, Katharine; Coates, Lucinda; van den Honert, Rob; Gissing, Andrew; Bird, Deanne; Dimer de Oliveira, Felipe; D’Arcy, Rebecca; Smith, Chloe; Radford, Deirdre (Elsevier BV, 2017-10)
    This paper documents the analysis of the circumstances surrounding fatalities due to flooding in Australia between 1900 and 2015. This longitudinal investigation is important to understand changing trends in social vulnerability and to inform efficient ...

    The availability of diverse ecological niches can promote adaptation of trophic specializations and related traits, as has been repeatedly observed in evolutionary radiations of freshwater fish. The role of genetics, environment, and history in ...
  • Brown, Lee E.; Khamis, Kieran; Wilkes, Martin; Blaen, Phillip; Brittain, John E.; Carrivick, Jonathan L.; Fell, Sarah; Friberg, Nikolai; Füreder, Leopold; Gislason, Gisli Mar; Hainie, Sarah; Hannah, David M.; James, William H. M.; Lencioni, Valeria; Olafsson, Jon S.; Robinson, Christopher T.; Saltveit, Svein J.; Thompson, Craig; Milner, Alexander M. (Springer Nature, 2017-12-18)
    Global change threatens invertebrate biodiversity and its central role in numerous ecosystem functions and services. Functional trait analyses have been advocated to uncover global mechanisms behind biodiversity responses to environmental change, but ...
