Spatial and temporal diet variability of Adélie (Pygoscelis adeliae) and Emperor (Aptenodytes forsteri) Penguin: a multi tissue stable isotope analysis
The Ross Sea, Antarctica, supports large populations of Emperor Penguin ( Aptenodytes forsteri ) and Adélie Penguin ( Pygoscelis adeliae ), two key...

Postnatal ontogeny of the spine of the Emperor Penguin Aptenodytes forsteri (Aves, Sphenisciformes) and modularity of the neck
The Emperor Penguin ( Aptenodytes forsteri ), the largest extant penguin, inhabits exclusively in Antarctica. Little is known about the spine of this...

Using telemetry data and the sea ice satellite record to identify vulnerabilities in critical moult habitat for emperor penguins in West Antarctica
We tracked adult emperor penguins from Rothschild Island, west Antarctic Peninsula in 2015/2016 during a summer with extensive sea ice of long...

Gephyromycinifex aptenodytis gen. nov., sp. nov., isolated from gut of Antarctic emperor penguin Aptenodytes forsteri
A novel actinobacterium NJES-13 T was isolated from the gut of Antarctic emperor penguin Aptenodytes forsteri . The new isolate produces bioactive...

An observation of a gentoo penguin Pygoscelis papua feeding an Adélie penguin P. adeliae chick
Interspecific feeding refers to behavior where an adult of one species feeds the young of another species, with the exclusion of brood parasitism. In...

Anthropogenic activities are associated with shorter telomeres in chicks of Adélie penguin (Pygoscelis adeliae)
Defining the impact of anthropogenic stressors on Antarctic wildlife is an active aim for investigators. Telomeres represent a promising molecular...

Can penguins (Spheniscidae) see in the ultraviolet spectrum?
It has been postulated that ultraviolet reflectance is important in mate choice in King Penguins Aptenodytes patagonicus , although not in other...

Fine-scale body and head movements allow to determine prey capture events in the Magellanic Penguin (Spheniscus magellanicus)
The identification of when, how and where animals feed is essential to estimate the amount of energy they obtain and to study the processes...

Fish-Birds at Home in Their Oceanic Habitats
Penguin distribution, like that of other seabirds, is not random but is closely related to water types/masses, ocean climate, and food availability....

Crary bank: a deep foraging habitat for emperor penguins in the western Ross Sea
Although most dives of emperor penguins ( Aptenodytes forsteri ) are less than 100 m, penguins from the Cape Washington colony regularly perform deep...
-
Penguindex: a Living Planet Index for Pygoscelis species penguins identifies key eras of population change
As one of the best studied components of the Southern Ocean food web, Pygoscelis penguins serve as an important window into the larger marine...

The importance of fine-scale landscape characteristics for habitat selection in penguins
Investigating the ecology of a species and the spatial requirements needed for their survival within an environment can improve and help develop...
-
Ecological Consequences of Diet Composition
In this chapter, we learn more specifically about who penguins’ competitors are, whether they are commercial fishing enterprises, other upper food...

Sea Food: The Fish-Bird Menu
The study of what penguins pursue, and eat, has a long history since the information is useful for gaining insights into their natural history....

Wading In: Introduction to Fish-Birds
In this introductory chapter, we explain why the first Europeans to encounter penguins at sea, back in the 1500s, were not all that far off in their...

Minimum anesthetic concentration of isoflurane and sevoflurane and cardiorespiratory effects of varying inspired oxygen fractions in Magellanic penguins (Spheniscus magellanicus)
The aim of this study was to determine the minimum anesthetic concentration of isoflurane (MAC ISO ) and sevoflurane (MAC SEVO ) and evaluate the...

Hot Penguins: Cold Water
It seems extraordinary for a hot bird, like a penguin, to live in such cold seas – after all, water sucks huge amounts of energy out of hot things...

Residues of anthropogenic origin found at Stranger Point/Cabo Funes, 25 de Mayo/King George Island, Antarctica
Since the Antarctic continent is not exempt from human disturbances, it is necessary to generate information on the residues of anthropogenic origin...

Decisions, Decisions, and More Decisions: How Fish-Birds Search for Prey
Penguins have highly specialized “hardware” that allows them to perform at high levels of athleticism to capture their prey. However, judicious...

The Slippery Shape, Hot Air, and the Powerhouse: How Fish-Birds Swim
Water, in contrast to air, is a hard taskmaster, exerting and interacting with draconian forces – weight (via gravity), upthrust (buoyancy), and drag...
