Full circumpolar migration ensures evolutionary unity in the Emperor penguin
Defining reliable demographic models is essential to understand the threats of ongoing environmental change. Yet, in the most remote and threatened areas, models are often based on the survey of a single population, assuming stationarity and independence in population responses. This is the case for...

Defining reliable demographic models is essential to understand the threats of ongoing environmental change.
