    • Arctic coastal benthos long-term responses to perturbations under climate warming: Climate change impact on Arctic benthos 

      Keck, Amalia; Kortsch, Susanne; Bluhm, Bodil; Beuchel, frank; Gulliksen, Bjørn; Ballantine, Carl; Cristini, Domiziana; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-31)
      <p>Climate warming influences structure and function of Arctic benthic ecosystems. Assessing the response of these systems to perturbations requires long-term studies addressing key ecological processes related to recolonization and succession of species. Based on unique time-series (1980–2017), this study addresses successional patterns of hard-bottom benthos in two fjords in NW Svalbard after a ...

    • Evidence of separate influence of moon and sun on light synchronization of mussel's daily rhythm during the polar night 

      Tran, Damien; Andrade Rodriguez, Hector Antonio; Camus, Lionel; Leopold, Peter; Ballantine, Carl; Berge, Jørgen; Durier, Guillaume; Sow, Mohamedou; Ciret, Pierre (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-09)
      Marine organisms living at high latitudes are faced with a light climate that undergoes drastic annual changes, especially during the polar night (PN) when the sun remains below the horizon for months. This raises the question of a possible synchronization and entrainment of biological rhythms under the governance of light at very low intensities. We analyzed the rhythms of the mussel <i>Mytilus</i> ...

    • Growth and behaviour of blue mussels, a re-emerging polar resident, follow a strong annual rhythm shaped by the extreme high Arctic light regime: Mussels' growth and behavior in Arctic 

      Tran, Damien; Andrade Rodriguez, Hector Antonio; Durier, Guillaume; Ciret, Pierre; Leopold, Peter; Sow, Mohamedou; Ballantine, Carl; Camus, Lionel; Berge, Jørgen; Perrigault, Mickael (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-14)
      Polar regions are currently warming at a rate above the global average. One issue of concern is the consequences on biodiversity in relation to the Northward latitudinal shift in distribution of temperate species. In the present study, lasting almost two years, we examined two phenological traits, i.e. the shell growth and behavioural rhythm of a recently re-established species in the high Arctic, ...

    • Temporal and spatial variation in a high Arctic bedrock macrobenthic community in Hinlopen, Svalbard. A baseline study related to possible climatic change 

      Ballantine, Carl (Master thesis; Mastergradsoppgave, 2013-08-15)
      Zonation patterns within a high Arctic, hard bottom community within the Hinlopen Strait, Svalbard were investigated using image analysis of underwater photoquadrates. This long term study consists of depth transects taken over a six year period were on a sublittoral vertical wall permanent monitoring station. Analysis indicated that the depth in which the greatest number of species occurred increased ...
