Population dynamics and production of small, marine copepods in highly seasonal Arctic and sub-Arctic environments
Barth-Jensen, Coralie (Doctoral thesis; Doktorgradsavhandling, 2023-03-17)Small copepods (≤ 2 mm) are highly abundant mesozooplankton in Arctic and sub-Arctic marine ecosystems. However, small copepods are generally underestimated in zooplankton studies because of the use of large-meshed nets (≥ 180-µm mesh size) and are relatively poorly studied compared to large copepods. This thesis investigates the egg hatching rates, population dynamics and production rates of three ... -
Temperature-dependent egg production and egg hatching rates of small egg-carrying and broadcast-spawning copepods Oithona similis, Microsetella norvegica and Microcalanus pusillus
Barth-Jensen, Coralie; Koski, Marja; Varpe, Øystein; Glad, Peter; Wangensteen, Owen S.; Præbel, Kim; Svensen, Camilla (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-07)Reproductive rates of copepods are temperature-dependent, but poorly known for small copepods at low temperatures, hindering the predictions of population dynamics and secondary production in high-latitude ecosystems. We investigated egg hatching rates, hatching success and egg production of the small copepods <i>Oithona similis</i> and <i>Microsetella norvegica</i> (sac spawners) and <i>Microcalanus ...
