Diatom phylogenies website

This weekend with the help of Novica (and Damjan a while back) we created a website called DiatomPhylogenies for storing and displaying published diatom phylogenetic trees. This website is meant as a repository for any tree of diatoms or algae. The trees are displayed in the wonderful OneZoom format. Check it out at diatoms.discindo.org or look at the “Diatom Phylogenies” repository on github. So far I’ve added three phylogenies: Thalassiosirales, Pinnularia, and all diatoms plus a whole bunch of other eukaryotes.  But I intend to populate the page with as many as I can get to.

If you like this idea and want to help populating the website, or just like to see your tree there, send me an email!


Epitypes of Diploneis species from Neogene fosill deposits

I just got word that another collaborative paper has been made available online. Phytotaxa published our taxonomic treatment of Diploneis species from Köpecz (a Neogene lacustrine deposit in Romania). We were working with fossil remains of diatoms from a large lake that existed more than 2.5 million years ago and is now dead. All that remains from this lake are its sediments where inorganic parts of diatoms have been preserved. Since diatoms have cell walls made out of silica they settled to the bottom of the lake and were preserved for few million years. The interesting thing is that these fossils might have very close relatives in some extant diatoms from Lake Ohrid (another of our study sites).

I have to thank Eci and Zlatko, my productive collaborators from the Institute of Biology at Faculty of Natural Sciences in Skopje, who lead this project as well as Krisztina and Nadja from Hungary and Bulgaria.
