Patterns of diversification and trait evolution in Australasian orchids

Role

Supervisor

Description

This project aims to investigate the evolutionary processes driving orchid species diversification in Australasia. For my first study group, the genus Bulbophyllum, I aim to explore the evolution of photosynthetic pathways and genome size in the genus Bulbophyllum across its distribution and interpret the findings in the context of the temporal evolution of lineages and the corresponding climatic shifts in Australia over geological time. My research builds on extensive published and unpublished phylogenetic and phylogenomic datasets for the genus Bulbophyllum comprising over 500 samples. I aim to generate a robust phylogenetic framework of Bulbophyllum, which will serve as a backbone for ancestral trait reconstruction of photosynthetic pathways and genome size evolution within the genus.
