This study identifies conserved ageing-associated genes in King penguins using methylome data and shows their relevance to human epigenetic age prediction.

The paper develops BEAC, an epigenetic clock for birds, validated across multiple species and showing strong predictive performance for chronological age.

This study tracks the spread and evolution of H5N1 in the sub-Antarctic and Antarctica, revealing long-distance dispersal and mammalian-adaptive mutations.

This paper introduces a method to incorporate classification uncertainty from machine learning into ecological models using Monte Carlo simulations, showing it leads to more reliable ecological estimates.

This study examines how king penguins mitigate the fitness costs of phenological mismatch through molecular stress response mechanisms.

The paper examines how multiannual environmental changes affect breeding phenology and success in king penguins over 24 years.

This study shows that Adelie penguin foraging effort and trip duration affect reproductive success under varying sea ice conditions, with clear thresholds indicating environmental stress.

The paper presents a high-quality chromosome-level genome of the king penguin, improving assembly contiguity and annotation for studying genotype-fitness relationships.

This study compares gene expression in Emperor and King penguins to identify adaptations to extreme Antarctic environments, finding key roles for muscle and liver in metabolism and regulatory shifts in the brain.

This study shows that sedentary life in zoo-housed King penguins accelerates epigenetic ageing, similar to humans, linked to methylation changes in metabolic and heart-related pathways.

This study finds that juvenile Adelie penguin survival in Antarctica declined by 32% from 2007 to 2020, linked to lower sea ice concentrations near natal colonies post-fledging.

The paper reports suspected H5N1 avian influenza cases in penguins and shags in Antarctica using PCR, indicating the virus's spread to the region.

The paper assesses sea ice changes in West Antarctica from 1985-2023, finding that critical thresholds were crossed in 2022-2023, likely impacting 9 of 10 emperor penguin colonies.
