When the going gets tough, the tough get going: Effect of extreme climate on an Antarctic seabird's life history
Abstract Individuals differ in many ways. Most produce few offspring; a handful produce many. Some die early; others live to old age. It is tempting to attribute these differences in outcomes to differences in individual traits, and thus in the demographic rates experienced. However, there is more t...
