Comment on “Lagged response of Adélie penguin (Pygoscelis adeliae) abundance to environmental variability in the Ross Sea, Antarctica”
Chen et al. (Polar Biology, 43(11):1769–1781) recently reported lagged, region-specific responses of Adélie penguin (Pygoscelis adeliae) abundance to...

I need some space: solitary nesting Adélie penguins demonstrate an alternative breeding strategy at Cape Crozier
According to the ‘selfish herd’ hypothesis, most seabird species breed colonially so that individuals can decrease their risk of predation by forming...

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...

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...

Molecular dietary analysis of Adélie (Pygoscelis adeliae) and Gentoo (Pygoscelis papua) penguins breeding sympatrically on Antarctic Ardley Island using fecal DNA
Penguins are one of the key components of the Antarctic ecosystem. Changes in penguin population size can indicate Antarctic ecosystem change. The...

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...

Pitfalls and advances in morphometric sexing: insights from the Adélie penguin Pygoscelis adeliae
Sexing weakly/criptically dimorphic birds requires invasive techniques or molecular analysis. Alternatively, sexing can be based upon morphometric...

Using latent behavior analysis to identify key foraging areas for Adélie penguins in a declining colony in West Antarctic Peninsula
Adélie penguins are considered indicators of Antarctic ecosystems. Their populations have declined by more than 50% in the West Antarctic Peninsula,...

A case of melanism in a Gentoo Penguin (Pygoscelis papua) at Esperanza/Hope Bay, Antarctica
Gentoo Penguin ( Pygoscelis papua ) is a species that reproduces in Antarctica and sub-Antarctic islands. During 2022 a Gentoo Penguin with an unusual...

Switching state-space models for modeling penguin population dynamics
Tracking individual animals through time using mark-recapture methods is the gold standard for understanding how environmental conditions influence...

Lagged response of Adélie penguin (Pygoscelis adeliae) abundance to environmental variability in the Ross Sea, Antarctica
Environmental variability drives Adélie penguin ( Pygoscelis adeliae ) population dynamics through its effects on vital rates (e.g., survival,...

Horizontal-vertical movement relationships: Adélie penguins forage continuously throughout provisioning trips
BackgroundDiving marine predators forage in a three-dimensional environment, adjusting their horizontal and vertical movement behaviour in response...

Distribution patterns of selenium and its fractions in penguin and seal colony soil profiles in response to their population dynamics in maritime Antarctica
Currently, most studies focus on the spatial distribution patterns of selenium (Se) and its fractions in the horizontal surface soils with much less...

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...

Osteohistology of the Antarctic penguin Pygoscelis adeliae (Aves, Sphenisciformes): definitive evidence of medullary bone
Osteohistological studies allow us to obtain valuable information on different aspects related to the bone microstructure, physiology and ecology of...

Fifty-year change in penguin abundance on Elephant Island, South Shetland Islands, Antarctica: results of the 2019–20 census
Elephant Island sits on the front lines of ecological change in the Scotia Arc region, but most of the island has remained unsurveyed for nearly...

Sea-ice and density-dependent factors affecting foraging habitat and behaviour of Adélie penguins throughout the breeding season
Seabird foraging activities are constrained by the heterogeneous distribution of prey, intra-specific competition, and the varying energy...

Are the diets of sympatric Pygoscelid penguins more similar than previously thought?
In recent years, functional changes in Southern Ocean are becoming more noticeable, due to climate change and increasing human impacts, including a...
