Evolution
. 2017 Jun;
53(3):932-937.
PMID: 28565639
Although phylogenetic hypotheses can provide insights into mechanisms of evolution, their utility is limited by our inability to differentiate simultaneous speciation events (hard polytomies) from rapid cladogenesis (soft polytomies). In...

Evolution
. 2017 Jun;
53(6):1936-1950.
PMID: 28565471
The glacial refugium hypothesis (GRH) proposes that glaciers promoted differentiation and generation of intraspecific diversity by isolating populations in ice-free refugia. We tested three predictions of this hypothesis for the...

Wallace S, Morris-Pocock J, Gonzalez-Solis J, Quillfeldt P, Friesen V
Mol Phylogenet Evol
. 2016 Nov;
107:39-47.
PMID: 27693526
Phylogenetic relationships among species can provide insight into how new species arise. For example, careful consideration of both the phylogenetic and geographic distributions of species in a group can reveal...

Morris-Pocock J, Anderson D, Friesen V
Mol Ecol
. 2011 May;
20(13):2835-50.
PMID: 21615811
Recent theoretical and empirical research suggests that statistical models based on coalescent theory can improve both phylogeographic and phylogenetic inference. An approach that involves elements of both statistical phylogeography (e.g....

Patterson S, Morris-Pocock J, Friesen V
Mol Phylogenet Evol
. 2010 Dec;
58(2):181-91.
PMID: 21144905
Gene trees will often differ from the true species history, the species tree, as a result of processes such as incomplete lineage sorting. New methods such as Bayesian Estimation of...

Morris-Pocock J, Steeves T, Estela F, Anderson D, Friesen V
Mol Phylogenet Evol
. 2009 Nov;
54(3):883-96.
PMID: 19931624
To test the hypothesis that both physical and ecological barriers to gene flow drive population differentiation in tropical seabirds, we surveyed mitochondrial control region variation in 242 brown boobies (Sula...

Morris-Pocock J, Taylor S, Birt T, Damus M, Piatt J, Warheit K, et al.
Mol Ecol
. 2009 Jan;
17(22):4859-73.
PMID: 19140977
Understanding the factors that influence population differentiation in temperate taxa can be difficult because the signatures of both historic and contemporary demographics are often reflected in population genetic patterns. Fortunately,...

Friesen V, Smith A, Gomez-Diaz E, Bolton M, Furness R, Gonzalez-Solis J, et al.
Proc Natl Acad Sci U S A
. 2007 Nov;
104(47):18589-94.
PMID: 18006662
The importance of sympatric speciation (the evolution of reproductive isolation between codistributed populations) in generating biodiversity is highly controversial. Whereas potential examples of sympatric speciation exist for plants, insects, and...
