Evolution 2018: assortative mating, combinatorial speciation and genome dynamics

The Evolution conference in Montpellier is over, and as the sun, wine and great science become a memory, here is my recap of some conference highlights following on from a great first day: A sea of scientists waiting for a … Continue reading

The eyes have it!

Eyes are pretty darn complicated, which makes them cool models for studying complex trait evolution.  Maybe the first time I realized how interesting eyes are when I saw this by the oatmeal about the amazing-ness of the mantis shrimp (are they your … Continue reading

Metabarcoding for every body, every habitat, every time

The immediate reason why I wanted to write about Boosting DNA metabarcoding for biomonitoring with phylogenetic estimation of operational taxonomic units’ ecological profiles is its usefulness for the scientific community and the effort of the authors to make their study reproducible. … Continue reading

Major new microbial groups expand diversity and alter our understanding of the tree of life

I still believe in revolutions. And sometimes they just happen, almost unnoticed. One such revolution happened on a boring 11th of April 2016 when Laura Hug et al. published their new tree of life in the journal of Nature Microbiology. … Continue reading

Molecular ecology, the flowchart

Update: You can now buy a poster print of the Flowchart, with proceeds going to support The Molecular Ecologist! Towards the end of last semester my department’s evolutionary genetics journal club read Rasmus Nielsen’s terrific 2005 review of tests for … Continue reading

It’s decorative gourd genetics season, muppet-huggers

It’s the first week of November, and we’re at Peak Pumpkin. Jack o’lanterns are passé, but Thanksgiving (in the U.S.) and traditional winter-solstice-adjacent holidays will keep pumpkin pie and its infamous espresso-based brethren in style for almost two more months. … Continue reading

On hyRAD-X, another option for museum genomics

Last year, I profiled Suchan et al.’s “hyRAD” method for reduced-representation genome sequencing of degraded sources of DNA using RAD probes. While it’s too early to say whether hyRAD will be widely used by molecular ecologists looking to integrate historic … Continue reading

The Hype Cycle of Ancient DNA

Recently I saw a graph that I’ve learnt is called the Hype Cycle and is a methodology used in assessment of new technologies and their marketing. What strikes me about it is how well it fits my own research field, … Continue reading

An Update on the Great BAMM Controversy

Update, 01 August 2016, 2:50PM. This post has been updated to include information contained in the supplemental material of Rabosky et al. 2017, and clarify the difference between branch-specific and tree-wide rate variation. Back in August, I summarized the main … 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
