Shared patterns of genomic diversity across populations of distantly related taxa

Genomic diversity is shaped by the complex interplay between the effects of genetic drift and natural selection among populations. Several of these effects, especially those of linked selection at neutral sites, adaptive introgression, and barriers to migration (often called “genomic … Continue reading

Polyploidy in the era of GBS

Ploidy, dear reader, is something that I think about literally all the time. It impacts every facet of my research from the field to the bench to the stats used to analyze data sets. It’s been simultaneously the greatest and the … Continue reading

Music to an amniote’s ears, an “accordion” model of genome size evolution

How did we get where we are? Genetically speaking, that is. A few posts ago, that whole genotype-phenotype question was discussed, how do genomes make plants and animals (and don’t forget the microbes!) look and act how they do. Another … Continue reading

Phylogenetic trees in R using ggtree

Recently, one R package which I like to use for visualizing phylogenetic trees got published. It’s called ggtree, and as you might guess from the name it is based on the popular ggplot2 package. With ggtree, plotting trees in R has … Continue reading
