An organism's life-history is the sequence of events related to growth, reproduction and survival that occur between conception and death. As life-history biologists, we are working to understand how variation in resource acquisition and resource allocation shapes variation in life-history traits in populations of free-living animals, and what it’s consequences are in terms of fitness and evolutionary trajectories. We use our study population of common terns, initiated by Prof. Dr. Peter Becker, to ask and answer questions, such as:
* Do natal conditions affect the adult phenotype?
* How does the phenotype change with age or environmental variation?
* Which physiological processes underlie such internally or externally induced plasticity?
* What is the (epi)genetic underpinning of key life-history traits and their plasticity?
* How and when does selection occur, and on which traits or trait combinations does it act?
* Is there a response to selection and thus a change in the genotypic distribution in the population?
Hereto, we analyse the long-term longitudinal dataset, safeguard the continuation of this dataset and perform experiments. We combine field and laboratory work with statistical modelling and hope to also expand our theoretical work.
