GENETIC DIVERGENCE, REPRODUCTIVE ISOLATION, AND MARINE SPECIATION
allopatric speciation dispersal molecular evolutio
font style='font-size:12px;'>
2015/12/17
In marine species, high dispersal is often associated with only mild genetic
differentiation over large spatial scales. Despite this generalization, there are
numerous reasons for the accumulation o...

Distribution of branch lengths and phylogenetic diversity under homogeneous speciation models
phylogenetic tree birth–death process Yule model branch length
font style='font-size:12px;'>
2011/9/23
Abstract: The constant rate birth--death process is a popular null model for speciation and extinction. If one removes extinct and non-sampled lineages, this process induces `reconstructed trees' whic...
The Moran model as a dynamical process on networks and its implications for neutral speciation
dynamical process networks implications
font style='font-size:12px;'>
2011/1/5
In genetics the Moran model describes the neutral evolution of a bi-allelic gene in a population of haploid individuals subjected to mutations. We show in this paper that this model can be mapped into...
