  The Tree of Life represents the complex relationships between all species, and recent advances in phylogenetic methods have dramatically expanded our ability to study these connections. However, there is still no universal ...

• Bridging the past to the present: investigating species boundaries with herbarium specimens and next-generation-sequencing. A case study of circumpolar Silene sect. Physolychnis 

  Quatela, Anne-Sophie (2023-10-30)

  During the recent decades, genetic information enclosed in herbarium collections have been partly revealed, largely due to the fast-moving high-throughput sequencing technologies. However, the genetic outcome from herbarium ...

• Morphological and chemical leaf traits of tropical montane tree species and their responses to warming 

  Manishimwe, Aloysie (2023-10-26)

  Leaf morphological and chemical traits of tropical trees vary along climate gradients, but it is currently unclear how they will respond to a rapidly warming climate and how this will vary among species. Considering this, ...

• Novel Marine Ingredients for Aquaculture - Fish Nutrition, Physiology and Intestinal Health 

  Warwas, Niklas (2023-10-24)

  Aquaculture is among the fastest growing food production sectors globally and supplies more fish to the growing human population than capture fisheries. One of the major challenges in salmonid aquaculture is to find ...

• Tomorrow is yesterday: early-life conditions shape ectotherm life histories 

  Hansson, Alexander (2023-09-29)

  Life history theory seeks to explain the overwhelming diversity of resource allocation strategies in nature by exploring how evolutionary forces optimise survival and reproduction within an organism’s environment. Central ...

• Phylogenetic Relationships, Biogeography and Species Delimitation: A case study on southern African Silene (Caryophyllaceae) 

  Moiloa, Ntwai (2023-09-20)

  The primary aim of this thesis was to explore the phylogenetic relationships and historical biogeography of African members of the plant genus Silene (Caryophyllaceae), with special focus on the eight native southern African ...

• Integrative physiology as a tool towards good animal welfare and sustainability in aquaculture: Focus on intestinal function and health 

  Hedén, Ida (2023-08-21)

  The human population is growing, and the world’s leaders are trying to provide humans with food resources and at the same time setting goals promoting sustainable food production. This means that we need to find new food ...

• Effects of contaminant mixtures on marine zooplankton diversity and function 

  Jönander, Christina (2023-05-02)

  Chemicals have important roles in our society and can be used as ingredients in personal care products, pesticides, pharmaceuticals, as well as be components of fuels used in cars or ships. More than 350 000 chemicals and ...

• Characterization of ion transport proteins involved in chloroplast function from land plants and algae 

  Dukic Marinkov, Emilija (2022-10-21)
