An epigenetic palimpsest: the King penguin's blood methylome reveals conserved hematopoietic ageing

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

The BEAC, an epigenetic clock for birds

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

Monte Carlo simulations to propagate the uncertainty of machine-learning classification into ecological models

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.

A long-lived seabird buffers the cost of phenological mismatch by modulating stress response

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

Multiannual environmental forcing shapes breeding phenology and success in a subantarctic seabird

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

Flexible foraging effort shapes Adelie penguin reproductive success across Antarctica and sea ice conditions

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.

Sedentary life accelerates epigenetic ageing in King penguins

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.

Declining juvenile survival of Adelie penguins in Antarctica

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.
