• Abundance, distribution and diversity of gelatinous predators along the northern Mid-Atlantic Ridge: A comparison of different sampling methodologies 

      Hosia, Aino; Falkenhaug, Tone; Baxter, Emily J.; Pages, Fransesc (Peer reviewed; Journal article, 2017-11-02)
      The diversity and distribution of gelatinous zooplankton were investigated along the northern Mid-Atlantic Ridge (MAR) from June to August 2004.Here, we present results from macrozooplankton trawl sampling, as well as ...
    • Biogeography of jellyfish in the North Atlantic, by traditional and genomic methods 

      Licandro, P; Blackett, M; Fischer, A; Hosia, Aino; Kennedy, J; Kirby, RR; Raab, R; Stern, R; Tranter, P (Peer reviewed; Journal article, 2015-07-15)
      Scientific debate on whether or not the recent increase in reports of jellyfish outbreaks represents a true rise in their abundance has outlined a lack of reliable records of Cnidaria and Ctenophora. Here we describe ...
    • Coincident mass occurrence of gelatinous zooplankton in Northern Norway 

      Knutsen, Tor; Hosia, Aino; Falkenhaug, Tone; Skern-Mauritzen, Rasmus; Wiebe, Peter H.; Larsen, Roger B.; Aglen, Asgeir; Berg, Erik (Peer reviewed; Journal article, 2018-05-23)
      In autumn 2015, several sources reported observations of large amounts of gelatinous material in a large north Norwegian fjord system, either caught when trawling for other organisms or fouling fishing gear. The responsible ...
    • Gelatinous zooplankton in western Norwegian fjords. Ecology, systematics and comparisons with adjacent waters 

      Hosia, Aino (Doctoral thesis, 2007-05-16)
      Gelatinous zooplankters, also known as jellies, are ubiquitous in the marine pelagic. Medusae, siphonophores and ctenophores are voracious predators that can, when abundant, have significant structuring effects on the ...
    • Identification of the polyp stage of three leptomedusa species using DNA barcoding 

      Schuchert, Peter; Hosia, Aino; Leclere, Lucas Pierre Jean (Peer reviewed; Journal article, 2017)
      DNA sequence data of hydromedusae and hydroids collected in the fjords near Bergen, Norway, permitted to connect three leptomedusae to three thecate hydroids with hitherto unknown life cycles. For all three species pairs, ...
    • Invasive ctenophore Mnemiopsis leidyi in Norway 

      Hosia, Aino; Falkenhaug, Tone (Peer reviewed; Journal article, 2015-03-18)
      We present data on the occurrence of the invasive ctenophore Mnemiopsis leidyi in Norway after the initial observations made in 2005. Our data comes from several net sampling investigations conducted along the Norwegian ...
    • Jellyfish summer distribution, diversity and impact on fish farms in a Nordic fjord 

      Halsband, Claudia; Majaneva, Sanna Kristiina; Hosia, Aino; Emaus, Per; Gaardsted, Frank; Zhou, Qin; Nøst, Ole Anders; Renaud, Paul Eric (Peer reviewed; Journal article, 2017)
      Jellyfish can cause high mortality of farmed fish and hence significant economic losses for the aquaculture industry. Despite their socio-economic importance, distribution and diversity data on gelatinous plankton are ...
    • Ocean current connectivity propelling the secondary spread of a marine invasive comb jelly across western Eurasia 

      Jaspers, Cornelia; Huwer, Bastian; Antajan, Elvire; Hosia, Aino; Hinrichsen, Hans-Harald; Biastoch, Arne; Angel, Dror; Asmus, Ragnhild; Augustin, Christina; Bagheri, Siamak; Beggs, Steven E.; Balsby, Thorsten J.S.; Boersma, Maarten; Bonnet, Delphine; Christensen, Jens T.; Dänhardt, Andreas; Delpy, Floriane; Falkenhaug, Tone; Finenko, Galina; Fleming, Nicholas E.C.; Fuentes, Veronica; Galil, Bella S.; Gittenberger, Arjan; Griffin, Donal C.; Haslob, Holger; Javidpour, Jamileh; Kamburska, Lyudmila; Kube, Sandra; Langenberg, Victor; Lehtiniemi, Maiju; Lombard, Fabien; Malzahn, Arne; Marambio, Macarena; Mihneva, Veselina; Møller, Lene Friis; Niermann, Ulrich; Okyar, Melek Isinibilir; Ôzdemir, Zekiye Birinci; Pitois, Sophie; Reusch, Thorsten B.H.; Robbens, Johan; Stefanova, Kremena; Thibault, Delphine; van der Veer, Henk W.; Vansteenbrugge, Lies; van Walraven, Lodewijk; Woźniczka, Adam (Peer reviewed; Journal article, 2018-07-24)
      Aim: Invasive species are of increasing global concern. Nevertheless, the mechanisms driving further distribution after the initial establishment of non‐native species remain largely unresolved, especially in marine systems. ...
