Members of the Rheindt Lab have in common a fascination for biodiversity and its underlying evolutionary processes. With the on-going biodiversity crisis on our planet, we are also interested in how knowledge of evolutionary processes can inform conservation.
Most of our research activities focus on the mechanisms that lead to – or sometimes act against – the build-up of biodiversity, such as genetic differentiation and introgression. Birds are our main model organism because their well-known distribution and life-history make them a suitable object for evolutionary studies. Pursuing a research project at my lab usually involves the application of a variety of laboratory approaches and contemporary computational tools, with a more recent focus on phylogenomic methods using Next-Generation sequencing approaches. Fieldwork is often, but not always, an important component of my students’ work.
Some of the projects the Rheindt Lab is involved in include:
(1)Genetic introgression: Genetic introgression is increasingly recognized as a pervasive phenomenon in evolutionary processes such as speciation and in the introduction of novelty into the gene pool. One of our main study foci is to examine the mechanisms of introgression. In particular, we are interested in the spatio-temporal patterns of introgression given different geographic and ecological conditions, and in whether selection or neutral processes are the main driver of introgression. We employ emerging technologies such as Next-Generation Sequencing in our introgression research.
One of the introgression models we have worked with is a clade of Neotropical tyrant-flycatchers (Zimmerius). Using a dataset of thousands of homologous markers from across the genomes of 12 flycatcher individuals, we have looked at signs of genetic introgression in a flycatcher population that is intermediate between two species. In the near future, we will be using similar approaches on a multitude of South-east Asian bird models.
(2)Complex radiations and leapfrog patterns: Advances in sequencing technology have opened up challenging new areas in evolutionary biology. We are about to analyze biogeographic leapfrog patterns and complicated explosive radiations in South-east Asian birds that are recent and therefore challenging to trace with traditional molecular markers. Using sequence data of genomic proportions and emerging analytical techniques, it will be possible to disentangle the evolutionary history of such complex radiations in unprecedented detail and explore the genomic landscape of differentiation and the neutral and selectional factors that may have shaped their diversification process.
(3) Biogeography in Wallacea: The Wallacean Region has had a major influence on our understanding of biogeography. Using his insights on animal distribution – especially birds – Alfred Russel Wallace delimited the area’s biogeographic regions along an improbable dividing line. Even so, the region’s avifauna remains virtually unexplored from a phylogenetic and population genetic perspective. This region has had a tumultuous earth-historic trajectory, involving impressive faunal turnover at localized as well as regional levels. Our aim is to use a thorough geographic sampling regime of birds coupled with modern phylogenomic methodology to illuminate regional biogeographic patterns against an earth-historic and paleo-climatic background of changing island connections. The results of this research will provide a solid foundation for understanding how biogeographic processes shape regional turnover.
