First reports of a mass mortality event across multiple life stages in a mesopelagic jellyfish in high latitude coastal waters
Bozman, Andrea; Aksnes, Dag Lorents; Eiane, Ketil (Peer reviewed; Journal article, 2018-04)Mass mortality events can occur naturally and may have important ecological impacts on local populations. The abundance and stage structure of the coronate scyphozoan Periphylla periphylla in a Northern Norwegian fjord ... -
Jellyfish distribute vertically according to irradiance
Bozman, Andrea; Titelman, Josefin; Kaartvedt, Stein; Eiane, Ketil; Aksnes, Dag Lorents (Peer reviewed; Journal article, 2017-03)We tested the hypothesis that the coronate jellyfish Periphylla periphylla distributes vertically according to a preferential range of absolute light intensities. The study was carried out in Lurefjorden, Norway, a fjord ... -
Timing of Calanus finmarchicus diapause in stochastic environments
Bandara, Kanchana; Varpe, Øystein; Maps, Frédéric; Ji, Rubao; Eiane, Ketil; Tverberg, Vigdis (Journal article; Peer reviewed, 2021)In environments with strong seasonality, many herbivorous zooplankton remain active only during the productive season and undergo a period of inactivity and suppressed development termed ‘diapause’ during the unproductive ... -
Two hundred years of zooplankton vertical migration research
Bandara, Kanchana; Varpe, Øystein; Wijewardene, Lishani; Tverberg, Vigdis; Eiane, Ketil (Journal article; Peer reviewed, 2021)Vertical migration is a geographically and taxonomically widespread behaviour among zooplankton that spans across diel and seasonal timescales. The shorter-term diel vertical migration (DVM) has a periodicity of up to 1 ...
