Physiological Response to Feeding in Little Penguins [PDF]

open access: yes, 2006
© 2006 by The University of Chicago.Specific dynamic action (SDA), the increase in metabolic rate above resting levels that accompanies the processes of digestion and assimilation of food, can form a substantial part of the daily energy budget of free ...

Bright and early: artificial light affects arrival time, but not group size or vigilance in Little Penguins (Eudyptula minor)

open access: yesIbis
Coastal developments are ever‐expanding and increasing the use of artificial lights within marine environments. Yet there is conflicting research on the impact of artificial lights on seabirds.

MORTALITY IN LITTLE PENGUINS (Eudyptula minor) ALONG THE COAST OF VICTORIA, AUSTRALIA [PDF]

open access: yesJournal of Wildlife Diseases, 1980
Forty-eight little penguins (Eudyptula minor) consisting of 21 (43.7%) mature, 18 (37.5%) juvenile and nine (18.7%) of undetermined age, from 10 Victorian coastal localities were examined during 1977-78. Thirty-seven (77%) of all penguins were in poor body condition with moderate to heavy burdens of internal and external parasites.

Carry-over body mass effect from winter to breeding in a resident seabird, the little penguin [PDF]

open access: yesRoyal Society Open Science, 2015
Using body mass and breeding data of individual penguins collected continuously over 7 years (2002–2008), we examined carry-over effects of winter body mass on timing of laying and breeding success in a resident seabird, the little penguin (Eudyptula ...

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

open access: yesFrontiers in Marine Science, 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 experiencing ...

Seasonal variations in the behavioural thermoregulation of roosting Humboldt Penguins (Spheniscus humboldti) in north-central Chile. [PDF]

open access: yes, 2004
We examined the thermoregulatory behaviour (TRB) of roosting Humboldt penguins (Spheniscus humboldti) in north central Chile during summer and winter, when ambient temperatures (Ta) are most extreme.

Validation of water flux and body composition in Glaucous gulls (Larus hyperboreus) [PDF]

open access: yes, 2006
Water influx rates (WIR) measured with tritiated water dilution were compared with direct measures of water and energy intake in glaucous gulls (Larus hyperboreus).

New Miocene Fossils and the History of Penguins in Australia.

open access: yesPLoS ONE, 2016
Australia has a fossil record of penguins reaching back to the Eocene, yet today is inhabited by just one breeding species, the little penguin Eudyptula minor.

Fine-scale dietary changes between the breeding and non-breeding diet of a resident seabird [PDF]

open access: yesRoyal Society Open Science, 2015
Unlike migratory seabirds with wide foraging ranges, resident seabirds forage in a relatively small range year-round and are thus particularly vulnerable to local shifts in prey availability.

Landscape genomics: natural selection drives the evolution of mitogenome in penguins

open access: yesBMC Genomics, 2018
Background Mitochondria play a key role in the balance of energy and heat production, and therefore the mitochondrial genome is under natural selection by environmental temperature and food availability, since starvation can generate more efficient ...
