Abstract:
|
Evolutionary change is best understood when considering its geographic context. Phylogeographic analyses aim to reconstruct both evolutionary and spatial history from molecular sequence data. One of the most promising, flexible approaches for phylogeographic inference is a Bayesian model that reconstructs spatial history on a continuous landscape using Brownian diffusion. Here, we extend the model by incorporating drift in the Brownian diffusion. By analyzing both simulated and real genetic data, we demonstrate an improved ability to uncover key aspects of spatial histories.
