Properties of consensus methods for inferring species trees from gene trees.
Consensus methods provide a useful strategy for summarizing information from a collection of gene trees. An important application of consensus methods is to combine gene trees to estimate a species tree. To investigate the theoretical properties of consensus trees that would be obtained from large numbers of loci evolving according to a basic evolutionary model, we construct consensus trees fro...
متن کاملConsistency and inconsistency of consensus methods for inferring species trees from gene trees in the presence of ancestral population structure.
In the last few years, several statistically consistent consensus methods for species tree inference have been devised that are robust to the gene tree discordance caused by incomplete lineage sorting in unstructured ancestral populations. One source of gene tree discordance that has only recently been identified as a potential obstacle for phylogenetic inference is ancestral population structu...
متن کاملImprovements to a Class of Distance Matrix Methods for Inferring Species Trees from Gene Trees
Among the methods currently available for inferring species trees from gene trees, the GLASS method of Mossel and Roch (2010), the Shallowest Divergence (SD) method of Maddison and Knowles (2006), the STEAC method of Liu et al. (2009), and a related method that we call Minimum Average Coalescence (MAC) are computationally efficient and provide branch length estimates. Further, GLASS and STEAC h...
متن کاملInferring reticulate evolution networks from consensus gene trees
Motivation: A major unresolved problem in phylogeny is to reconstruct the evolutionary history of a set of species when it cannot be modeled by a simple tree. When a reticulation event, such as hybrid speciation or horizontal transfer, occurs, separate regions of a species’ genetic data may evolve along different trees. Our approach uses the gene trees for each region to solve the inverse probl...
متن کاملInferring Species Trees from Gene Trees in a Radiation of California Trapdoor Spiders (Araneae, Antrodiaetidae, Aliatypus)
BACKGROUND The California Floristic Province is a biodiversity hotspot, reflecting a complex geologic history, strong selective gradients, and a heterogeneous landscape. These factors have led to high endemic diversity across many lifeforms within this region, including the richest diversity of mygalomorph spiders (tarantulas, trapdoor spiders, and kin) in North America. The trapdoor spider gen...
