Spring fun for FEZ!

To celebrate the wave of sunny weather here in Oslo, members of the FEZ group decided to go on a sunny spring hike up Grefsenkollen together. At the top we were greeted by a fantastic view of Oslo and the fjord, great food from the Grefsenkollen restaurant, and […]

Group of the Month: Monogenea

Monogeneans are a group of parasitic flatworms (Platyheminthes). The group is species-rich and systematists assign them to a class within the flatworms. Together with flukes (class Trematoda) and tapeworms (class Cestoda) they form the superclass Neodermata. The name-giving feature Neodermata is that the original epidermis is replaced by a […]

The mitochondrial gene order of Annelida – extremely old, but still working

Mitochondria are the energy plant of our cells. Originally, they were bacteria, but then they were captured by the ancestors of eukaryotes (among others all animals, mushrooms and plants) and used to produce energy for the cell. This is also known as the endosymbiotic theory. An inheritance from […]

The measure of our reach: understanding evolution when our models break down.

Last week I was lucky enough to have another paper come out, this time in BMC Bioinformatics: “nRCFV: a new, dataset-size-independent metric to quantify compositional heterogeneity in nucleotide and amino acid datasets” It’s a less elegant title than usual, I’ll admit! In addition, for a biological paper, there […]

Group of the month: Feather duster worms (Annelida, Sabellidae)

This month it is time for another group of polychaetes, the family Sabellidae. Sabellids are present from intertidal to abyssal marine waters all around the world (Rouse et al. 2022). They inhabit both soft substrates such as sand or mud and hard substrates such as rocks or coral […]

Staphylinid beetles, 24 new genetic markers and new insights into their taxonomy – Jørgen’s defence

Yesterday, Jørgen Hansen Starholm defended his Master thesis “Solving phylogenetic relationships within the Rove beetle genus Aleochara (Coleoptera: Staphylinidae) by utilizing a novel approach based on High Throughput Sequencing” successfully. The purpose of the thesis was to infer a phylogeny of Aleochara based on more nuclear markers and […]

Systematics and ecosystem function – can they go together?

In the summer of last year, Zoologica Scripta organized an international symposium around the topic of ‘The role of systematics for understanding ecosystem functions’ in the premises of Norwegian Academy of Sciences and Letters in Oslo. The symposium aimed at offering a forum for exploring and discussing trends […]

Tardigrades, Public Databases and Science From Your Settee

Last week, as part of a special issue of Zoologica Scripta, I started the year with my first paper – and my first solo effort! “The Wealth of Shared Resources: Improving molecular taxonomy using eDNA and public databases” is a rather portentous title for a pretty simple experiment. […]

Group of the month: Nemertea

This month’s group of animals on the spotlight are nemerteans, also known as ribbon worms, vermiform creatures belonging to the phylum Nemertea. They include more than 1300 species, typically long and slender with soft contractile bodies. Most nemerteans are marine, predominantly benthic or bottom dwellers, but some species […]

Group of the Month: Diphyllobothrium

Known as broad or fish tapeworms, these spaghetti impersonators are some of the largest parasites that can infect humans. Transmitted to humans via undercooked or raw fish meat, Diphyllobothrium are found in fresh and marine waterways around the world. Characterized as flatworms, they are also considered pseudophyllidean cestodes, […]
