Beware of the parasites in chaetognaths!

Parasites infest arrow worms and jellies, trying to get to fish. We need molecular and morphology data to know who these parasites are, who the hosts are, and how often and when exactly they occur.

This MSc project includes:

  • Sampling opportunities in diverse sites in Norway
  • Learning techniques at the DNA lab (DNA barcoding) and the morphology lab (identification and taxonomy)
  • Phylogenetic and molecular species delimitation analysis
  • Joining activities for outreach and science popularization​
  • Presenting in academic events and potentially being part of ​a peer-reviewed publication​

​Interested? Contact Luis MartellJoan J Soto Angel, or Aino Hosia

Several species of calycophoran and physonect siphonophores are considered bipolar (Arctic and Antarctic). Pics by Joan J. Soto-Angel

According to the literature, some siphonophore species occur in both polar regions and their corresponding neighbouring waters, but are they really the same species or not? How similar/related are they?

This MSc project includes:

  • Sampling opportunities in the Arctic
  • Learning techniques at the DNA lab (DNA barcoding) and the morphology lab (identification and taxonomy)
  • Phylogenetic and molecular species delimitation analysis
  • Joining activities for outreach and science popularization​
  • Presenting in academic events and potentially being part of ​a peer-reviewed publication
  • Participation in European Project POLE2POLE (Horizon2020)

The diversity of Arctic hydrozoans in Norway is still poorly understood, despite the fact that these animals are important habitat-formers (some new habitats in Norwegian waters have been described based on them!).

Rhizocaulus verticillatus is the only species of Rhizocaulus in Norway... or is it not?

For example, only 1 species of the hydrozoan genera Symplectoscyphus and Rhizocaulus are supposed to occur in the country, but preliminary data on genetic variation suggest there’s more than meets the eye.

Are we about to discover a new species or is this variation normal for Arctic hydroids? Help us find out!
