    • The paradox of searching efficiency or why are violent population cycles so uncommon in terrestrial ecosystem 

      Oksanen, Lauri; Vuorinen, Katariina Elsa M; Oksanen, Tarja Maarit (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-19)
      The searching efficiency of predators depends on the balance between the adaptations of the predator and the counter-adaptations of the prey. In this evolutionary race, the prey should normally have the upper hand, as it can perform tradeoffs between efficiency in resource use and ability to avoid predators. In terrestrial predator–herbivore systems, however, the huge difference in food quality ...
    • Contrasting life cycles of Southern Ocean pteropods alter their vulnerability to climate change 

      Gardner, Jessie; Peck, Victoria L.; Bakker, Dorothee C. E.; Tarling, Geraint A.; Manno, Clara (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-11)
      Pteropods are a key part of biogeochemical cycling and epipelagic food webs in the Southern Ocean. However, shelled pteropods are vulnerable to climate change, due to their aragonite shells being particularly sensitive to ocean acidification. Currently our understanding of pteropod responses to environmental change is hindered by uncertainties surrounding their life cycles and population dynamics. ...
