Where do penguins go during the inter-breeding period? Using geolocation to track the winter dispersion of the macaroni penguin.
Although penguins are key marine predators from the Southern Ocean, their migratory behaviour during the inter-nesting period remains widely unknown. Here, we report for the first time, to our knowledge, the winter foraging movements and feeding habits of a penguin species by using geolocation sensors fitted on penguins with a new attachment method. We focused on the macaroni penguin Eudyptes c...
متن کاملIdentifying Risk: Concurrent Overlap of the Antarctic Krill Fishery with Krill-Dependent Predators in the Scotia Sea
Mitigating direct and indirect interactions between marine predators and fisheries is a motivating factor for ecosystem-based fisheries management (EBFM), especially where predators and fisheries compete for a shared resource. One difficulty in advancing EBFM is parameterizing clear functional responses of predators to indices of prey availability. Alternative characterizations of fishery-preda...
متن کاملThe Influence of Otolithes ruber Consumption on Prey and Comparison with that Harvested by Fisheries
The Otolithes ruber is considered a valuable fish in the Indo-West Pacific. Estimates of the Q/B ratio and parameters of equations to ‘predict’ Q/B values for O. ruber in northwestern part of the Persian Gulf and the effects of different age-groups (age 1 to 6 year) on prey are presented. The age and food item of O. ruber were recorded on data collected from monthly samplings by bottom tra...
متن کاملEnergetics of diving in macaroni penguins.
Heart rate (fH), abdominal temperature (T(ab)) and diving depth were measured in thirteen free-ranging breeding female macaroni penguins. Measurement of these variables allowed estimation of the mass-specific rate of oxygen consumption (V(O(2))) while diving and investigation of the physiological adjustments that might facilitate the diving behaviour observed in this species. In common with oth...
متن کاملCorticosterone predicts foraging behavior and parental care in macaroni penguins.
Corticosterone has received considerable attention as the principal hormonal mediator of allostasis or physiological stress in wild animals. More recently, it has also been implicated in the regulation of parental care in breeding birds, particularly with respect to individual variation in foraging behavior and provisioning effort. There is also evidence that prolactin can work either inversely...
