Inter‐population variation in demographic responses to environmental changes: insights from four seabird populations Open
The variability in responses to environmental change between populations remains poorly quantified and understood. This shortcoming has major consequences, as variation and flexibility of life‐history traits between populations contribute …

Temporal and spatial equivalence in demographic responses of emperor penguins (<i>Aptenodytes forsteri</i>) to environmental change Open
Population ecology and biogeography applications often necessitate the transfer of models across spatial and/or temporal dimensions to make predictions outside the bounds of the data used for model fitting. However, ecological data are oft…

Linking differences in personality to demography in the wandering albatross Open
Population dynamics are shaped by individual differences. With a good understanding of the relationships between individual differences and vital rates, population models can be improved to yield more realistic and detailed demographic pro…

Migration behaviour, wintering areas and conservation biology of brown skuas breeding in the subtropical Amsterdam Island Open
Invasive non-native species are a major threat to seabirds, leading to the implementation of numerous eradication campaigns. However, eradication can also affect non-targeted species. There are concerns over the fact that the invasive mamm…

Seabird distribution in the Southern Indian Ocean from four decades of at sea surveys Open
Seabirds are conspicuous and important marine predators. They mostly forage on a diversity of zooplankton (copepods, euphausiids, amphipods) and nekton (squid and fish) prey. Because of their position in the trophic web, high energy requir…

Climate Change Impacts Pair‐Bond Dynamics in a Long‐Lived Monogamous Species Open
Climate change can influence populations of monogamous species by affecting pair‐bond dynamics. This study examined the impact of climate on widowhood and divorce, and the subsequent effects on individual vital rates and life‐history outco…

Wintering strategies of two king penguin populations of the Southern Indian Ocean Open
The king penguin Aptenodytes patagonicus is an important model species of the Southern Ocean. While there is extensive knowledge on the foraging movement of this species during the summer in the early chick-provisioning period, little info…

Plastic Behaviour Buffers Climate Variability in the Wandering Albatross Open
Climate change has marked effects on global weather patterns and oceanic systems, impacting animal behaviour and fitness in potentially profound ways. Despite this, we lack detailed information about species' responses to climatic variatio…

Fine-scale behaviour and population estimates of endangered sooty albatross suggest low exposure (while not excluding high sensitivity) to bycatch Open
Recent developments in assessing species-specific seabird bycatch risks have demonstrated that fine-scale approaches are essential tools to quantify interactions with fishing vessels and to understand attraction and attendance behaviours. …
View article: Ecological niche segregation between sympatrically breeding blue petrels and thin-billed prions
Ecological niche segregation between sympatrically breeding blue petrels and thin-billed prions Open
Ecological niche theory predicts coexisting species will segregate spatially, temporally or trophically to limit competition. Few studies have investigated niche segregation in multiple dimensions during the breeding season in sympatric, m…

Brooding duration does not depend on cat predation risk but is related to weather and phenology in the wandering albatross (<i>Diomedea exulans</i>) Open
Parental investment increases offspring fitness at the expense of the parent's ability to invest in other offspring. In many animal species, parents guard their offspring after birth. The parental decision over the duration of this period …

Bottom‐up effects drive the dynamic of an <span>A</span>ntarctic seabird predator–prey system Open
Understanding how populations respond to variability in environmental conditions and interspecific interactions is one of the biggest challenges of population ecology, particularly in the context of global change. Although many studies hav…

Habitat preferences of <i>Phoebetria</i> albatrosses in sympatry and allopatry Open
Aim Competition is often proposed to drive niche segregation along multiple axes in speciose communities. Understanding spatial partitioning of foraging areas is particularly important in species that are constrained to a central place. We…

The impact of boldness on demographic rates and life‐history outcomes in the wandering albatross Open
Differences among individuals within a population are ubiquitous. Those differences are known to affect the entire life cycle with important consequences for all demographic rates and outcomes. One source of among‐individual phenotypic var…

The challenges of independence: ontogeny of at-sea behaviour in a long-lived seabird Open
The transition to independent foraging represents an important developmental stage in the life cycle of most vertebrate animals. Juveniles differ from adults in various life history traits and tend to survive less well than adults in most …

Climate change drives migratory range shift via individual plasticity in shearwaters Open
How individual animals respond to climate change is key to whether populations will persist or go extinct. Yet, few studies investigate how changes in individual behavior underpin these population-level phenomena. Shifts in the distributio…
