It is now well known that incomplete lineage sorting can cause serious difficulties for phylogenetic
inference, but little attention has been paid to methods that attempt to overcome these …

… This work complements Lacey Knowles’s research on the timing and pattern of speciation
in Melanoplus grasshoppers (Knowles 2000; Knowles 2000, 2001a,b), and Wayne Maddison’…

Genetic data are frequently used to delimit species, where species status is determined on
the basis of an exclusivity criterium, such as reciprocal monophyly. Not only are there …

Statistical phylogeographic studies contribute to our understanding of the factors that
influence population divergence and speciation, and that ultimately generate biogeographical …

… BC Carstens, LL Knowles, Estimating species phylogeny from gene-tree probabilities
despite incomplete lineage sorting: An example from Melanoplus … L. Lacey Knowles 1 …

STEM is a software package written in the C language to obtain maximum likelihood (ML)
estimates for phylogenetic species trees given a sample of gene trees under the coalescent …

Phylogeography's objective—to understand the processes underlying the spatial and
temporal dimensions of genetic variation—underlies both the prominence and extensive …

There is a long‐standing debate over whether or not the Pleistocene glaciations promoted
speciation. While some models predict that extensive mixing of populations during interglacial …

Estimating phylogenetic relationships among closely related species can be extremely
difficult when there is incongruence among gene trees and between the gene trees and the …

The role of ecology in the origin of species has been the subject of long-standing interest to
evolutionary biologists. New sources of spatially explicit ecological data allow for large-scale …
