Can thermoclines be a cue to prey distribution for marine top predators? A case study with little penguins. [PDF]

PLoS ONE, 2012
The use of top predators as bio-platforms is a modern approach to understanding how physical changes in the environment may influence their foraging success.

The consequences of chaos: Foraging activity of a marine predator remains impacted several days after the end of a storm.

PLoS ONE, 2021
As extreme weather is expected to become more frequent with global climate change, it is crucial to evaluate the capacity of species to respond to short-term and unpredictable events.

Strouhal number analysis for the swimming of little penguin (Eudyptula minor): Proof of efficient underwater propulsion

Results in Engineering, 2023
Penguins are the utmost specialized wing-propelled divers as their flapping action is accountable for the entire underwater propulsion. However, numerical evidence of how efficient their underwater propulsion is has not been studied to date.

Unpacking the Lifelong Secrets of Little Penguins: Individual Quality, Energy Allocation, and Stochasticity in Defining Fitness.

Evolution; international journal of organic evolution, 2023
While the heterogeneity among individuals of a population is more and more documented, questions on the paths through which it arises, particularly whether it is linked to fixed heterogeneity or chance alone, are still widely debated. Here, we tested how

Breeding success in Southern Australian Little Penguins is negatively correlated with high wind speeds and sea surface temperatures

Ornithological Applications, 2021
As bio-indicators, seabirds across the globe help us understand how our environment is changing, and how this is affecting our wildlife. Little Penguins (Eudyptula minor) in Australia are a key species in understanding the changes to the Australian ...

Effects of the presence of zoo visitors on zoo-housed little penguins (Eudyptula minor)

New Zealand journal of zoology, 2021
Little penguins (Eudyptula minor), or Kororā in Māori, show variation in their behavioural responses towards zoo visitors in Australian zoos. We experimentally examined the effects of visitor presence on the behaviour and stress physiology of little ...

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

Vision, 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 confocal

Fossil plotopterid seabirds from the Eo-Oligocene of the Olympic Peninsula (Washington State, USA): descriptions and functional morphology. [PDF]

PLoS ONE, 2011
The plotopterids (Aves, Plotopteridae) were a group of extinct wing-propelled marine birds that are known from Paleogene-aged sediments (Eocene to Miocene), mostly around the Pacific Rim (especially Japan and the northwest coast of North America).
