PhD thesis topic

           Biodiversity - particularly in the tropics - is under ever increasing threat due to human activities. Our ability to make informed decisions on how to protect biodiversity in the long run largely depends on our understanding of the evolutionary patterns and processes that have been shaping biodiversity. Across all levels of biological organization, evolutionary biology provides the fundamental context and framework for comparative analyses of biodiversity and its implications. Studying what happened in the past is crucial for gaining a better perception of the actual forces shaping biodiversity. The overall number of species we see today is a very small fraction of what has ever existed - most of them are extinct. The Earth’s surface is dynamic as well, and vegetation history is critical for understanding the evolution of modern land biomes.

           Is present-day biodiversity the result of a gradual accumulation of new lineages over time? Is it the result of recent and rapid diversification (speciation) events? Or is it the result of a combination of both? How has Earth’s history (geology and climate) affected diversification and extinction events? Which processes shape the current geographic distribution of biological lineages? These are fundamental questions in evolutionary biology for which we still lack satisfactory answers, especially when referring to tropical regions. We will address the questions outlined above by combining molecular, fossil and current geographic distribution data in a model group of tropical flowering plants: Thunbergioideae (Acanthaceae).

          Our main goals are (i) to produce a genomic data set for Acanthaceae, (ii) to identify hundreds of new molecular markers for phylogenetic analyses, (iii) to build robust phylogenetic hypotheses for relationships within Thunbergioideae, and (iv) to infer the geographic history of the subfamily. We are producing new empirical data using next generation sequencing (NGS), attempting complete species sampling for this lineage. So far, there exists no such data set for any Amazonian clade. Our research will contribute crucial data and analyses needed to elucidate processes that shape tropical biodiversity.
