A deep dive into fat: Investigating blubber lipidomic fingerprint of killer whales and humpback whales in northern Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-01)In cetaceans, blubber is the primary and largest lipid body reservoir. Our current understanding about lipid stores and uses in cetaceans is still limited, and most studies only focused on a single narrow snapshot of the lipidome. We documented an extended lipidomic fingerprint in two cetacean species present in northern Norway during wintertime. We were able to detect 817 molecular lipid species ... -
Foraging movements of humpback whales relate to the lateral and vertical distribution of capelin in the Barents Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-24)Understanding how individual animals modulate their behaviour and movement patterns in response to environmental variability plays a central role in behavioural ecology. Marine mammal tracking studies typically use physical environmental characteristics that vary, and/or proxies of prey distribution, to explain predator movements. Studies linking predator movements and the actual distributions ... -
The influence of prey distribution on marine top predator movements
(Doctoral thesis; Doktorgradsavhandling, 2023-12-08)Predation is an ecological process that relies on spatial and temporal co-occurrence of predators and their prey. In marine ecosystems, killer and humpback whales are considered sentinels of ecosystem health, given their critical roles as top predators in shaping marine food webs and their responsiveness to ecosystem changes. As they are seldom influenced by natural threats, they are model species ... -
Predation research with electronic tagging
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-15)Predation is a fundamental aspect of ecology that drives ecosystem structure and function. A better understanding of predation can be facilitated by using electronic tags that log or transmit positions of predator or prey species in natural settings, however, there are special considerations that must be made to avoid biased estimates. We provide an overview of the tools available for studying ...
