Population Genetics

Genetic diversity and connectivity in plant species differing in clonality and dispersal mechanisms in wetland island habitats.

In plants, long-distance dispersal is both attenuated and directed by specific movement vectors, including animals, wind, and/or water. Hence, movement vectors partly shape metapopulation genetic patterns that are, however, also influenced by other …

Evolutionary stability, landscape heterogeneity, and human land‐usage shape population genetic connectivity in the Cape Floristic Region biodiversity hotspot.

As human‐induced change eliminates natural habitats, it impacts genetic diversity and population connectivity for local biodiversity. The South African Cape Floristic Region (CFR) is the most diverse extratropical area for plant biodiversity, and …

Population assignment reveals low migratory connectivity in a weakly structured songbird

Understanding migratory connectivity is essential for determining the drivers behind population dynamics and for implementing effective conservation strategies for migratory species. Genetic markers provide a means to describe migratory connectivity; …

Population Graph Stability

A population graph is a network structure based upon inter-stratum conditional genetic covariance (see Dyer & Nason 2004 for a more complete discussion). In this context, it is often of interest to know the statistical stability of your loci in determining the topology you see in the popgraph.

Evolutionary genomics of gypsy moth populations sampled along a latitudinal gradient

The European gypsy moth (Lymantria dispar L.) was first introduced to Massachusetts in 1869 and within 150 years has spread throughout eastern North America. This large‐scale invasion across a heterogeneous landscape allows examination of the genetic …


The program STRUCTURE is an ubiquitous feature of many population genetic studies these days—if it is appropriate is another question. Today, while covering model based clustering in population genetics, we ran into a problem where STRUCTURE was unable to run and the OS said it was Corrupted and should be thrown away. Jump below for our fix, it really is an easy one.

Inbreeding (Positive Assortative Mating based on Genotype)

Here are the slides for the lecture on inbreeding.

Effective Population Size

How big is the data set you are analyzing? Apparently it depends on how you count…

Here are the online presentations for Chapter 2: Hardy Weinberg Equilibrium from the upcoming text, Applied Population Genetics. More information on this text can be found here.

Applied Population Genetics Textbook Release

I will be posting portions of all 10 chapters of my upcoming textbook, Applied Population Genetics, as early draft chapters to this website over the spring semester.
