Available master projects

Atlantic salmon parr density and sex ratio in the Tana river

Supervisor: Kenyon Mobley

This project involves analyzing a dataset of Atlantic salmon parr collected over 8 years in the Utsjoki river, a tributary of the Tana (Teno) River. Different parr age classes (0+, 1+, 2-3+), maturity, collection area, and genetic information on sex were collected. The goal is to see whether different areas of the sampling area have different densities and sex ratios due to location and year. The student should have familiarity or willing to learn R programming language and statistics.

Historical salmon and trout genetics

Supervisors: Kenyon Mobley and Claire-Elise Fischer (UiT Museum)

This project involves extracting DNA from archaeological collections of salmonid bones using ancient DNA techniques at the UiT Museum. The goal will be to identify species using DNA barcoding and age the samples using stable isotope analysis. 

Cleaning out the closet: Reference databases and taxonomic classifiers for metabarcoding data

Supervisor: Mads Reinholdt Jensen

Online databases, such as those hosted by the National Center for Biotechnology Information (NCBI) and the Barcode of Life Data System (BOLD), are essential for taxonomic identification of animal DNA sequences derived from metabarcoding data of community or environmental DNA samples. However, these databases often contain misidentified reference sequences, which can undermine their reliability for biologically meaningful inferences if not carefully curated. In this project, the student will focus on a specific taxonomic group of interest (e.g., fishes, echinoderms, annelids, molluscs. etc.) and explore bioinformatic tools for auditing and curating reference databases. Additionally, the student will evaluate the performance of various taxonomic classifiers (e.g., custom classifiers, LCA, and RDP-classifier) to provide insights and recommendations for improving the use of metabarcoding data in future research.

Simulations of ancient eDNA

Supervisors: Mads Reinholdt Jensen + Daniel Kumazawa Morais

Ancient environmental DNA provides valuable insights into past biological communities, offering a window into historical biodiversity. However, DNA degrades over time, resulting in highly fragmented sequences, thus complicating taxonomic identification. Additionally, reference databases used for taxonomic inference are heavily biased towards certain organism groups, and significant variability exists in bioinformatic filtering approaches and data interpretation. These challenges raise critical questions about the reliability and resolution of taxonomic assignments from ancient eDNA data. In this project, the student will conduct DNA simulation experiments to quantify biases in taxonomic inference and establish minimum filtering criteria for reliable analyses. The project is entirely computational and will involve working with large datasets on a high-performance computing infrastructure. The student should have an interest in learning bioinformatics and be motivated to explore the complexities of ancient eDNA analysis.
