Evolution in mosses

Monitoring Zackenberg. Photo: Kristian Hassel.Bryophytes were among the first organisms to conquer land for about 480 million years ago. While many organisms have gone extinct on the way to present, bryophytes are still one of the most important groups of land plants. Are you interested in evolutionary questions like speciation, relationship between species (phylogeny) or the history behind species distribution patterns (phylogeography)? We are also engaged in applied research related to conservation biology and effects of climate change.

Evolutionary genomics of museum collections

Evolutionary genomics of museum collections Mike Martin

 

An untapped wealth of specimens lies in wait within the world’s natural history collections. We use cutting-edge sequencing and evolutionary genomic analysis approaches to reconstruct the evolution of genomes and populations using both ancient and modern DNA, usually involving plants. Skills in basic scripting/coding are extremely valuable in this work.

Some inspiration for potential M.Sc. projects:

  1. Gene enrichment and population genomic structure in historical (1845-52) samples of the potato pathogen Phytophthora infestans, which caused the Irish potato famine.
  2. Sequencing historical samples of the invasive plant common ragweed (Ambrosia artemisiifolia) to determine the genomic basis of its success.
  3. Whole-genome phylogenetic analysis and functional diversity of ‘Darwin’s finches of the plant world’, the Galápagos daisy trees (genus Scalesia).
  4. Spatial phylogenetic analysis of plant diversity at vastly different taxonomic levels, from intra-species to the entire flora of Norway.

Freshwater invertebrates

DNA barcoding. Photo: Torbjørn Ekrem.Genetic and morphological diversity of non-biting midges (Diptera: Chironomidae). MSc thesis on this topic will typically focus on species diversity and/or phylogenetic relationships in non-biting midges and involve analyses of molecular as well as morphological data. DNA barcoding for identification and association of life stages are central in this work and Masters projects usually involve both field- and laboratory work.

Marine fjord migration and habitat use of anadromous brown trout Salmo trutta

Marine fjord migration and habitat use of anadromous brown trout Salmo trutta

Akustisk merke opereres inn i buken på sjøørret i Nidelva Foto Aslak Sjurse.During our studies on anadromous brown trout (sea trout), we try to reveal the underlying causes between different marine migratory strategies. Examples of research questions are if aquaculture, water temperature or levels of salinity influence migratory behaviour, habitat use or growth in the marine environment. Such information will be important in order to evaluate if dynamic environmental changes may confine the marine feeding migration of sea trout. Project: Sjøørretens hemmelige liv

Please contact Jan Grimsrud Davidsen for more information.

Marine invertebrates

Nakensneglen_Limacia_clavigera. Photo:_Torkild BakkenHow many species do we have, and where do they live? Marine environments hold a large biodiversity, actually a lot more than we know. In both shallow coastal waters and the deep areas of the Norwegian Sea we discover a hidden biological diversity. Genetic and morphological diversity of different organism groups may be studied to reveal the magnitude of biological diversity, and their distribution.

A master project typically includes field- and lab work. Please contact Torkild Bakken if you want more information about projects, marine worms or sea slugs.

Vascular plants and lichens

Illustrasjon: Mika Bendiksby.Molecular systematics of vascular plants or lichens. These master projects study hereditary molecular differences at various taxonomic levels, mainly in DNA sequences, to reveal the evolutionary history of an organism. Various approaches to multi-locus DNA sequencing can be used, including traditional Sanger sequencing and various target enrichment HTS approaches. Data will be analysed phylogenetically, and resulting hypotheses of relationships will form the basis for further analyses of character-evolution, historical biogeography and taxonomy. Projects will involve both field- and laboratory work. Molecular, ecological and morphological data will be obtained from freshly collected material as well as from historical specimens housed in various herbaria.

Please contact Mika Bendiksby for more information.

Woody plants, herbivores and climate change

Master student fieldwork. Photo: james Speed.How do climate and herbivory interact to determine ecosystem change? The annual ring record in woody plants provides a window to the past, allowing us to infer previous environmental conditions. Measuring tree rings in trees and shrubs taken from areas with known herbivore densities we can disentangle the impacts of climate and ungulate herbivores on the establishment and growth of trees and shrubs.
