Preferred project period: September 2024 – June 2026

 

Background

Anthropogenic drivers such as climate change, eutrophication, and overfishing, are putting coastal marine systems under pressure. While changes in biodiversity have been observed they are difficult to predict and prevent, most likely due to our knowledge gaps of species interactions. We believe that a detailed understanding of how the food webs is structured is a vital piece of information to establish ecologically and economically effective countermeasures.

Project description

In this project, the student(s) will carry out experiments to characterize the gut content of Copepods from the Skagerrak and Oslofjord by reconstructing the food web utilization of these predators by targeting both their prey, and the prey of the prey through DNA metabarcoding. Furthermore, the students will perform stable isotope analyses to obtain the trophic state and origin of primary production underlying the food sources by the analysis of copepods. In the Oslofjord, primary production on land has been suggested to become a more and more important component of the marine food web.

There will be two projects with one student focusing on the analysis of samples from copepods using metabarcoding. In the second project, the student will perform stable isotope analyses on tissue samples. The students will have access to existing data and participate in existing sampling surveys.

Learning outcomes

In addition to critical thinking and report writing, the student will develop skills in experimental design and laboratory work, particularly, DNA metabarcoding or stable isotope, bioinformatics, and multivariate analysis. The project includes laboratory work at UiO and potential work visits to XXX and eDNA solutions laboratory in Gothenburg/Sweden. The project will include occasional sampling cruises in Oslofjord, to collect samples.

What we offer

We offer an inclusive and stimulating research environment where the student is encouraged to join the research group activities and engage with other students and researchers at AQUA. This work will be part of the project “Coastal Ecosystem Dynamics under Anthropogenic Pressures” https://www.mn.uio.no/ibv/english/research/sections/aqua/research-projects/coastal-ecosystems/index.html
