The trial lecture is: "Translating population genomics to applied conservation biology – opportunities and challenges".

Time and place: October 21, 2022 10:15 AM, Zoom and Nucleus, Bikuben, The Kristine Bonnevie building.

The events will also be live streamed using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the events.

The events opens for participation just before they start, and closes for new participants approximately 15 minutes after it has begun.

Main research findings

Climate change and human activities are currently affecting species around us in a variety of ways. For instance, many species are expanding their range and settling further north in the northern hemisphere as the climate is warming. There is a lack of knowledge of how a range expansion affects the expanding species. Newly established populations may thrive or fail, and the ability to adapt to new conditions and prosper differs from species to species. In this thesis, I studied the reed warbler (Acrocephalus scirpaceus), a migratory bird which is expanding its range northwards in Europe into Fennoscandia, but has also recently colonised Malta in the south of Europa. I looked at changes in observable characteristics of the birds, and at their genetic material. To learn more about the reed warbler's genes, I assembled the entire genome of the reed warbler. I found that the different European populations are very similar genetically, but there is some novel variation in the newly established populations. I also found that the reed warblers are highly adaptable, and responsive to climatic conditions. The success of the reed warbler's range expansions is in contrast with many other species that are negatively affected by our changing world.
