Seabirds are sensitive indicators of changes in marine ecosystems and might integrate and/or amplify the effects climate forcing on lower levels food chains. Current knowledge impact penguins is primarily based Antarctic birds identified by using flipper bands. Although bands have helped to answer many questions about penguin biology, they were shown some species a detrimental effect. Here, we present for Subantarctic species, king (Aptenodytes patagonicus), reliable results effect survival...
The Strategic Plan for Biodiversity, adopted under the auspices of Convention on Biological Diversity, provides basis taking effective action to curb biodiversity loss across planet by 2020—an urgent imperative. Yet, Antarctica and Southern Ocean, which encompass 10% planet’s surface, are excluded from assessments progress against Plan. situation is a lost opportunity conservation globally. We provide such an assessment. Our evidence suggests, surprisingly, that region so remote apparently...
The view from the south is, more than ever, dominated by ominous signs of change. Antarctica and Southern Ocean are intrinsic to Earth system, their evolution is intertwined with influences course Anthropocene. In turn, changes in Antarctic affect presage humanity's future. Growing understanding countering popular beliefs that pristine, stable, isolated, reliably frozen. An aspirational roadmap for science has facilitated research since 2014. A renewed commitment gathering further knowledge...
Like many polar animals, emperor penguin populations are challenging to monitor because of the species' life history and remoteness. Consequently, it has been difficult establish its global status, a subject important resolve as environments change. To advance our understanding penguins, we combined remote sensing, validation surveys using Bayesian modelling, estimated comprehensive population trajectory over recent 10-year period, encompassing entirety species’ range. Reported indices...
Abstract Suspected cases of Highly Pathogenic Avian Influenza (H5N1) were detected in Adélie penguins and Antarctic shags at the southernmost latitude so far Antarctica, two breeding sites out 13 visited, using highly specific PCR assay. These first records mark progression H5N1 panzootic into Antarctica.
Changes in seabird populations, and particularly of penguins, offer a unique opportunity for investigating the impact fisheries climatic variations on marine resources. Such investigations often require large-scale banding to identify individual birds, but significance data relies assumption that no bias is introduced this type long-term monitoring. After 5 years using an automated system identification king penguins implanted with electronic tags (100 adult were transponder tag, 50 which...
The outcome of coevolutionary interactions is predicted to vary across landscapes depending on local conditions and levels gene flow, with some populations evolving more extreme specializations than others. Using a globally distributed parasite colonial seabirds, the tick Ixodes uriae , we examined how host availability geographic isolation influences this process. In particular, sampled ticks from 30 six different seabird species, three in Southern Hemisphere Northern Hemisphere. We show...
How natural climate cycles, such as past glacial/interglacial patterns, have shaped species distributions at the high-latitude regions of Southern Hemisphere is still largely unclear. Here, we show how post-glacial warming following Last Glacial Maximum ( ca 18 000 years ago), allowed (re)colonization fragmented sub-Antarctic habitat by an upper-level marine predator, king penguin Aptenodytes patagonicus . Using restriction site-associated DNA sequencing and standard mitochondrial data,...
Significance Penguins have long been of interest to scientists and the general public, but their evolutionary history remains unresolved. Using genomes, we investigated drivers penguin diversification. We found that crown-group penguins diverged in early Miocene Australia/New Zealand identified Aptenodytes (emperor king penguins) as sister group all other extant penguins. first occupied temperate environments then radiated cold Antarctic waters. The Circumpolar Current’s (ACC)...
We argue the need to improve climate change forecasting for ecology, and importantly, how relate long-term projections conservation. As an example, we discuss effective management of one species, emperor penguin, Aptenodytes forsteri. This species is unique amongst birds in that its breeding habit critically dependent upon seasonal fast ice. Here, review vulnerability ongoing projected change, given sea ice susceptible changes winds temperatures. consider published future penguin population...

Abstract The King penguin ( Aptenodytes patagonicus ) is an iconic species of the Southern Ocean and currently being developed as a model-in-the-wild for understanding evolution. We present high-quality, haplotype-resolved 1.35 Gb chromosome-level genome adult female - ‘Pen/Se-guin’ from Crozet Archipelago, assembled using PacBio HiFi long-read sequencing Hi-C proximity data. 94.93% assembly assigned to 34 chromosomes (32 autosomes, plus Z W chromosomes), with BUSCO completeness 97.2%, k...
ABSTRACT The king penguin is one of the champion avian divers, surpassed only by its larger relative, emperor penguin. foraging ecology penguins typically studied during austral summer, when trips are relatively short (weeks). Consequently, little known about autumn–winter period, birds undertake long (months) and descent their preferred prey to greater depth might challenge dive capacity. Investigating behaviour seven from Crozet Islands autumn–winter, we found that conducted deeper longer...
Understanding the trade-off between current reproductive effort, future survival and breeding attempts is crucial for demographic analyses life history studies. We investigated this in a population of king penguins (Aptenodytes patagonicus) marked individually with transponders using multistate capture-recapture models. This colonial seabird species has low annual proportion non-breeders (13%), despite cycle which lasts over 1 year. To draw inferences about consequences non-breeding, we...
Abstract Defining reliable demographic models is essential to understand the threats of ongoing environmental change. Yet, in most remote and threatened areas, are often based on survey a single population, assuming stationarity independence population responses. This case for Emperor penguin Aptenodytes forsteri , flagship Antarctic species that may be at high risk continent-wide before 2100. Here, using genome-wide data from whole continent, we reveal this top-predator organized as one...
