My research focuses on radiations and the evolutionary dynamics of species diversification. The unevenness of species richness is a well documented characteristic of the tree of life, however fundamental questions, such as why some lineages diversify more than others, and at differing rates, remain unanswered. My current work as a PhD-student forms part of the ‘Biogeography and Evolutionary Dynamics of Legume Diversification’ research project, run by Dr. Colin Hughes. For my part in this project I am focusing on the genus Lupinus.
Lupinus is a legume genus comprising ca. 276 annual and perennial species of plants distributed across a range of habitats from sea-level to 5,000m, with centres of diversity in North, Central and South America. Present day diversity is thought to be a result of a series of parallel and nested replicate continental scale radiations that show some of the highest known rates of net diversification in plants. While there is evidence that a shift from annual to perennial habit acted as a possible key innovation, allowing lineages to expand into upland environments, the extent and monophyly of these clades remain poorly tested due to incomplete taxon sampling, and detailed diversification trajectories of these radiations remain poorly understood due to lack of phylogenetic resolution. The project aims to investigate why Lupinus radiated in Central and South America and the mechanisms by which species diversified so rapidly.
