Thank you @dackslabecb.bsky.social for all your effort in making our (protistologists) society journal stronger. I am also particularly stocked to be among the recipients of the William Trager Award for the “outstanding paper in the Journal of Eukaryotic Microbiology” in 2024.

The extraordinary diversity, biology and complexity of #protists pose significant challenges to the #genomics community. That’s why a new collaboration will look to address some of the major technical barriers for sequencing protists from bulk cultures and the environment.

I do not want to start an online discussion, but these clades were named without morphological data or cultures. I find this deeply disappointing. The usual etiquette is to leave such clades provisionally as “Novel Clade X”, leaving the honour of naming them to those who formally describe the taxon.
