Effects of caloric restriction and maternal age on offspring fitness
Caloric restriction (keeping individuals on restricted diets through life) has been shown to prolong life in many organisms, including daphnia. However, there is much less knowledge on consequences of starvation for other life history aspects than survival. In particular, caloric restriction could affect the next generation of offspring through maternal effects - and these effects may in turn also depend on a mother's age. In this project we are seeking a master student interested in investigating whether maternal age can interact with caloric restriction to affect the fitness of offspring (e.g., through epigenetic effects), using the water flea Daphnia magna as study organism. The student will design the experiment in collaboration with the supervisors.

Daphnia magna is a model organism for a range of questions in ecology and evolutionary biology. The lab work of this project will include maintenance of lab cultures of D. magna and their algae food resource, in addition to performing the experiments. Lab experiments will include the use of video measurements and image analyses for monitoring individual development.
Students will be included in a friendly and stimulating working environment including PhD candidates and post docs, with opportunities for collaboration.
The project will give the student a strong training by combining experimental work with statistical analyses.
