They were interested in how such variation with an heritable component could be maintained over evolutionary time, and therefore studied fitness consequences for three years in a wild population of great tits. Selection was fluctuating between years, between the sexes and pair-combinations of personality was found to be important

pied flycatcher, and that local populations declined as a result of increased asynchrony between breeding time and the date of the local food peak. He is mostly interested in how different organisms can respond with different mechanisms and speeds to the high rates of current climate change, and the consequences this has for trophic interactions.

Since 2001 Christiaan Both mostly worked on the effects of climate change on trophic interactions, with an emphasis on changes phenology. Together with Marcel Visser he showed that climate change resulted in an insufficient response in timing of migration and egg-laying in the long-distance migratory

Christiaan Both studied density dependent reproduction during his PhD, where he aimed to understand why birds lay smaller clutches when competition increased. This work was both using long-term data from hole-breeding passerines, and also experimental. It showed that great tit clutch size is causally

affected by local density, and that the density dependent response could be explained by an optimal response of individuals to the level of competition for food during the nestling phase.
