The Chrysophyte order Synurales is unique by including microscopic organisms which produce silica scales of extraordinary variety and complexity. Interestingly, virtually no hypotheses were raised to explain the adaptive mechanisms of decorative elements, though these are extremely variable and species-specific.
This project will focus on disentangling the evolutionary dynamics and adaptive function of decorative elements by the combination of molecular phylogenetics, experimental scale morphogenesis and computer modelling. Growing experiments under different environmental conditions and computer-aided design (CAD) analyses will be used to investigate the adaptive potential and mechanical behaviour of silica scales equipped by various ornamental structures.
Selected questions asked:
Is the development of decorative elements correlated with past climatic changes?
Do specific decorative elements act as an adaptation to specific environments?
May the structure of scale affect the ability of the cell to scatter the ultraviolet radiation?
Which ornamental structures improve the mechanical strength of the silica case?
What are the size and shape limits of particular ornamental structures, keeping the strength properties and structural integrity of silica scales?
We are looking for a motivated student, ideally trained in CAD-aided structure design and modelling (e.g. finite element analyses).
