Lay summary

The uneven distribution of species richness across evolutionary lineages is one of the most pervasive and fundamental features of biodiversity across all groups of organisms. The reasons why some lineages diversify and others do not, why some groups are species-rich and others are not, and the underlying factors determining these differences, are crucial to understanding how life became so diverse, and how diversity evolves. One approach to address these questions involves estimating rates of species diversification, assessing variation in diversification rates among different evolutionary lineages, and localising diversification rate shifts to particular points in time and space, using phylogenetic trees. Potential ecological, geographical and adaptive life history factors associated with these rate shifts can then be examined to see what could have caused episodes of rapid evolutionary diversification.

 

The Biogeography and Evolutionary Dynamics of Legume Diversification Project aims to address these questions using one of the largest, most evolutionarily successful, and economically important families of flowering plants, the legumes. New empirical data for two contrasting legume lineages, the genusLupinus, with around 275 species, and the subfamily Mimosoideae, with more than 3,000 species, will be used to gain insights into diversification patterns across broad geographical and ecological spans, and time frames. Key gaps in taxonomic knowledge in each group will be plugged to determine the species richness of groups. Both these plant study groups include multiple episodes of very rapid continental-scale species diversification, sometimes called radiations, thereby offering novel opportunities to compare the diversification trajectories of multiple lineages simultaneously across time and space. This research involves field work to assemble plant material, herbarium collections based work to understand morphological diversity, and laboratory work to assemble DNA sequence data, as well as large-scale phylogenetic and diversification analyses.

Abstract

The uneven distribution of species richness across evolutionary lineages is one of the most pervasive and fundamental features of biodiversity across all organismal groups. The reasons why some lineages diversify and others do not, why some clades are species-rich and others are not, and the underlying factors determining these differences, are crucial to understanding how diversity evolves. However, these questions have hardly been explored and remain poorly understood. To address these questions we need a better understanding of the dynamics of diversification. This involves estimating rates of species diversification, assessing among-lineage variation in diversification rates, localising rate shifts to particular branches on phylogenetic trees, and examining potential ecological, geographical and adaptive life history correlates of diversification. Recent methodological and technical advances in comparative phylogenetics, coupled with a proliferation of molecular phylogenetic data and progress in documenting taxonomic diversity, mean that these goals have gathered fresh momentum. These developments open the way for new insights into the geotemporal patterns of diversification, and prospects to develop a general framework of the dynamics of diversification. This proposal aims to address these questions using one of the largest and most evolutionarily successful families of flowering plants, the legumes. New empirical data for two contrasting legume lineages, the genus Lupinus and the subfamily Mimosoideae, will be used to gain insights into diversification patterns across broad geographical and ecological spans and time frames. DNA sequence data will be used to reconstruct time-calibrated phylogenies for these two clades with enhanced taxon sampling, resolution and support. Key gaps in documentation of taxonomic diversity in each group will be plugged to be able to determine the species richness of monophyletic terminal clades. These data will form the basis for estimating species diversification rates, testing among-lineage variation in diversification rates to locate rate shifts, and analysing the significance of correlations between diversification rate shifts and derived ecological and life history traits and geographical range shifts. Both study groups include multiple continental-scale radiations offering novel opportunities to compare the diversification trajectories of multiple lineages simultaneously across time and space.
