Mechanisms of population divergence along elevational gradients in the Tropics
Elucidating the mechanisms that give rise to population divergence and eventually initiate speciation is a key step for understanding the evolution of biodiversity. Most theories of differentiation and speciation have traditionally focused on geographically isolated populations. However, there is growing evidence that speciation can occur due to divergent selection despite initially high gene flow. My doctoral dissertation project investigates the effects of environmental heterogeneity and geography in promoting phenotypic and genetic divergence along elevation gradients in natural populations ...
