Exploring subcolony differences in foraging and reproductive success: the influence of environmental conditions on a central place foraging seabird

Autor: Jessica Pulvirenti, Richard D. Reina, Andre Chiaradia

Publikováno v: Royal Society Open Science, Vol 10, Iss 6 (2023)

While differences in foraging and reproductive success are well studied between seabird colonies, they are less understood at a smaller subcolony scale. Working with little penguins (Eudyptula minor) at Phillip Island, Australia, we used an automated

Variability in prey field structure drives inter-annual differences in prey encounter by a marine predator, the little penguin

Publikováno v: Royal Society Open Science, Vol 9, Iss 9 (2022)

Understanding how marine predators encounter prey across patchy landscapes remains challenging due to difficulties in measuring the three-dimensional structure of pelagic prey fields at scales relevant to animal movement. We measured at-sea behaviour

Oceanic thermal structure mediates dive sequences in a foraging seabird

Autor: Xavier Meyer, Andrew J. J. MacIntosh, Andre Chiaradia, Akiko Kato, Francisco Ramírez, Cédric Sueur, Yan Ropert‐Coudert

Publikováno v: Ecology and Evolution, Vol 10, Iss 13, Pp 6610-6622 (2020)

Abstract Changes in marine ecosystems are easier to detect in upper‐level predators, like seabirds, which integrate trophic interactions throughout the food web. Here, we examined whether diving parameters and complexity in the temporal organizatio

Tracing Seal Predation Back to the Source Colony of Their Penguin Prey: A Trace Element and Stable Isotope Analysis

Autor: Sarah-Lena Reinhold, Simon D. Goldsworthy, John P.Y. Arnould, Bronwyn M. Gillanders, Sean D. Connell, Rebecca R. McIntosh

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

Marine predators recovering from historic, commercial, over-harvesting can create conservation challenges when they prey on vulnerable species. Pinniped predation of seabirds presents one such challenge and identifying the source colonies experiencin

Confocal and Electron Microscopic Structure of the Cornea from Three Species of Penguin

Autor: Peter W. Hadden, Akilesh Gokul, Satya Amirapu, Ratish Kurian, Charles N. J. McGhee, Jie Zhang

Publikováno v: Vision, Vol 7, Iss 1, p 4 (2023)

Corneal confocal microscopy has not previously been performed in penguins, despite recognition of its unusually flat shape. To identify features that the penguin shares with other birds and or mammals and those specific to penguins, we undertook conf
