• Male mate choice and selectivity in relation to female mating status in the seed beetle Callosobruchus maculatus 

  Rousseau, Sidonie Edith Jeannine (Master thesis, 2021-06-01)

  Sexual selection plays a role in evolution and often follows the pattern where males are fighting to mate, while females are choosy due to their higher gamete investment. Males can also be selective if they have high costs ...

• Comparing density of lumpfish (Cyclopterus lumpus) used in aquaculture to different welfare indicators 

  Berg, Magnus Sunason (Master thesis, 2021-05-31)

  Farmed lumpfish are commonly used as cleaner fish in the salmonid aquaculture industry, but a knowledge gap exists with regards to their density. Filling this knowledge gap is of importance, as the lumpfish have no swim ...
