    • Biological introduction risks from shipping in a warming Arctic 

      Ware, Christopher; Berge, Jørgen; Jelmert, Anders; Olsen, Steffen M.; Pellisier, Loic; Wisz, Mary S.; Kriticos, Darren J.; Semenov, Georgy; Kwasniewski, Sawomir; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-14)
      Several decades of research on invasive marine species have yielded a broad understanding of the nature of species invasion mechanisms and associated threats globally. However, this is not true of the Arctic, a region where ongoing climatic changes may promote species invasion. Here, we evaluated risks associated with non-indigenous propagule loads discharged with ships' ballast water to the high-Arctic ...

    • Climate change, non-indigenous species and shipping: assessing the risk of species introduction to a high-Arctic archipelago 

      Ware, Christopher; Berge, Jørgen; Sundet, Jan Henry; Kirkpatrick, JB; Coutts, A.D.M.; Jelmert, Anders; Olsen, SM; Floerl, O; Wisz, Mary S.; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Aim: Anticipated changes in the global ocean climate will affect the vulnerability of marine ecosystems to the negative effects of non-indigenous species (NIS). In the Arctic, there is a need to better characterize present and future marine biological introduction patterns and processes. We use a vector-based assessment to estimate changes in the vulnerability of a high-Arctic archipelago to marine ...

    • Past Arctic aliens have passed away, current ones may stay 

      Alsos, Inger Greve; Ware, Christopher; Elven, Reidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-04)
      Increased human activity and climate change are expected to increase the numbers and impact of alien species in the Arctic, but knowledge of alien species is poor in most Arctic regions. Through field investigations over the last 10 years, and review of alien vascular plant records for the high Arctic Archipelago Svalbard over the past 130 years, we explored long term trends in persistence and ...

    • Prevention of microbial species introductions to the arctic: The efficacy of footwear disinfection measures on cruise ships 

      Rumpf, Sabine Bettina; Alsos, Inger Greve; Ware, Christopher (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-06)
      Biosecurity measures are commonly used to prevent the introduction of non-native species to natural environments globally, yet the efficacy of practices is rarely tested under operational conditions. A voluntary biosecurity measure was trialled in the Norwegian high Arctic following concern that non-native species might be transferred to the region on the footwear of travellers. Passengers aboard ...
