Prey predictability and preparation versus recovery breathing strategies in European shags Gulosus aristotelis (L.) diving in different habitats
Carlsen, Astrid A.; Wright, Jonathan; Lorentsen, Svein-Håkon; Lea, Stephen E.G. (Peer reviewed; Journal article, 2023)A recent study on the diving behaviour of European shags (Gulosus aristotelis (L.)) foraging in kelp forests off rocky coasts of Norway suggests surface durations are related only to the duration of the preceding dive, and ... -
Recovery, body mass and buoyancy: a detailed analysis of foraging dive cycles in the European shag
Carlsen, Astrid A.; Lorentsen, Svein-Håkon; Wright, Jonathan (Peer reviewed; Journal article, 2021)Foraging dives in birds and mammals involve complex physiological and behavioural adaptations to cope with the breaks in normal respiration. Optimal dive strategies should maximize the proportion of time spent under water ... -
Temporal non-independence of foraging dive and surface duration sequences in the European shag Gulosus aristotelis
Carlsen, Astrid A.; Lorentsen, Svein-Håkon; Mattisson, Jenny; Wright, J. (Peer reviewed; Journal article, 2023)Studies of foraging behaviour and respiratory physiology in breath-holding divers often assume that each dive cycle (dive plus surface duration) is physiologically and ecologically independent within a series (or “bout”) ...
