Published: May 2021

Mitochondrial chromosomes have diversified among eukaryotes and many different architectures and features are now acknowledged for this genome. Here we present the improved HERMES index, which can measure and quantify the amount of molecular change experienced by mitochondrial genomes. We test the improved approach with ten molecular phylogenetic studies based on complete mitochondrial genomes, representing six bilaterian Phyla. In most cases, HERMES analysis spotted out clades or single species with peculiar molecular synapomorphies, allowing to identify phylogenetic and ecological patterns. The software presented herein handles linear, circular, and multi-chromosome genomes, thus widening the HERMES scope to the complete eukaryotic domain.

Syllis Savigny in Lamarck, 1818, the type genus of Syllidae, is the largest and most diverse within the family. This genus presents many taxonomic, biogeographic, and phylogenetic problems due mainly to the lack of molecular data and morphological synapomorphies for many of the species, but also due to poor or inadequate descriptions. In order to improve our understanding of the genus, we have undertaken a morphological revision of Australian species, based on type material and material collected over years by the Australian Museum.

Identification of a tetrahedral apical cell preserved within a fossilized fern fiddlehead.

Institute of Molecular Plant Sciences, University of Edinburgh, Max Born Crescent, EH9 3BF Edinburgh, UK. Electronic address:

The gradual unfurling of fronds from tightly coiled tips, termed fiddleheads or croziers, is one of the most recognizable features of the fern lineage, but its evolutionary origin remains unclear. Here, we identify that fiddleheads and their development, termed circinate vernation, are not ubiquitous across ferns. Instead, they are a synapomorphy of a clade we term the circinatophytes that includes extant marattioid and leptosporangiate ferns.

Molecular phylogenetics of nursery web spiders (Araneae: Pisauridae).

Mol Phylogenet Evol

February 2025

Department of Biological Sciences, The George Washington University, 2029 G St. NW, Washington, DC 20052, USA.

Pisauridae Simon, 1890, or nursery web spiders, are a large family with a worldwide distribution and very diverse life history strategies. Despite being named for their nursery webs, similar structures are built by some members of Ctenidae, Trechaleidae, and Oxyopidae. Pisauridae has no known morphological synapomorphies that circumscribe all members of the family, and delineation of subfamilies has been a longstanding issue.
