Molecular systematics, taxonomy and museomics of tropical Ramalinaceae
In this PhD project, I aim to establish relationships of, and delimit taxa for tropical Ramalinaceae, in particular for the genus Phyllopsora s. lat. Special focus will be on species delimitation within Phyllopsora s. str. Based on multi-locus DNA sequence phylogenetics, thin-layer chromatography, and morphological/anatomical investigations, I will revise old taxa and describe new when necessary. Obtained phylogenies will be used to test hypotheses about character evolution. A DNA-barcode library for Phyllopsora species will be generated and made publicly available through the Barcode of Life Data Systems (BOLD).
