Survival in macaroni penguins and the relative importance of different drivers: individual traits, predation pressure and environmental variability
Understanding the demographic response of free-living animal populations to different drivers is the first step towards reliable prediction of population trends. Penguins have exhibited dramaticExpand

Unravelling the relative roles of top‐down and bottom‐up forces driving population change in an oceanic predator
Abstract In the open ocean ecosystem, climate and anthropogenic changes have driven biological change at both ends of the food chain. Understanding how the population dynamics of pelagic predatorsExpand

Humpback whales wintering at Pitcairn Island, South Pacific
Here we present the first documentation of humpback whales (Megaptera novaeangliae) in the Pitcairn Island region. Land-based surveys were conducted from Pitcairn Island from June 2007 to August 2007Expand

Love thy neighbour or opposites attract? Patterns of spatial segregation and association among crested penguin populations during winter
Aim Competition for food among populations of closely related species and conspecifics that occur in both sympatry and parapatry can be reduced by interspecific and intraspecific spatial segregation.Expand

Drivers of intrapopulation variation in resource use in a generalist predator, the macaroni penguin
Intrapopulation variation in resource use occurs in many populations of generalist predators with important community and evolutionary implications. One of the hypothesised mechanisms for suchExpand

The relative importance of opposing drivers in determining population change in macaroni penguins Eudyptes chrysolophus
It is widely recognised that both nutrient-driven processes acting from the “bottom-up” and predator-driven processes acting from the “top-down” are important drivers of population change. However,Expand

Do krill fisheries compete with macaroni penguins? Spatial overlap in prey consumption and catches during winter
Aim To infer the potential for competition between an important Antarctic predator, the macaroni penguin, and the krill fishery by examining the spatial overlap in prey consumption and catches.Expand

When is enough … enough? Effective sampling protocols for estimating the survival rates of seabirds with mark-recapture techniques
ABSTRACT Capsule: Lower intensity mark-recapture studies, such as those undertaken by citizen scientists, provide an opportunity to improve the spatial representation of survival estimates for birds.Expand
