    The complete mitogenome of Buccinum undatum obtained from transcriptome analysis is presented here. The mitogenome is 15,265 bp in length and comprises 13 protein-coding genes, 2 ribosomal subunit genes, and 22 transfer RNAs. The complete genome was ...
  • Barðadóttir, Þórný (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2025-06)
    This doctoral research explores the entanglements of placemaking, mobilities and the making of margins in the context of tourism. The research examines how places come to be and are transformed in relation to various mobilities within as well as through ...
  • Loftsdóttir, Kristín; Skaptadóttir, Unnur Dís; Hafsteinsson, Sigurjón Baldur (Háskólaútgáfan, 2020-12-18)
    Iceland has increasingly been tangled in a dense network of various mobilities, leading to the growing transnational character of Icelandic society. This means that Iceland is involved in and affected by different forms of exchange and flows of ideas, ...
  • Thórhallsdóttir, Gyda (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2025-06-23)
    This study evaluates a novel methodological approach for analyzing tourism mobility patterns in time and space within regions characterized by core-periphery mobility patterns, with Iceland and its key nature-based destinations serving as the study ...
  • Sveinbjornsdottir, Sigrun; Thorsteinsson, Einar; Lingam, Govinda Ishwar (Cambridge University Press (CUP), 2017)
    A two-dimensional theory of adolescent coping with cross-cultural and cross-Human Development Index Categories (HDI) application was tested: the Measure of Adolescent Coping Strategies (MACS). The MACS was answered by 809 adolescents of diverse origins ...
