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 […]

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 […]

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 […]

Door 8: GENESPACE tracks regions of interest and gene copy number variation across multiple genomesss multiple genomes.” Elife 11 (2022): e78526.

During this year Frontiers in Evolutionary Zoology advent calendar I have decided to briefly present you three works: a research paper, a researcher interview, and a book. The first door to which I am contributing if this quite useful method paper to whoever is currently working with whole […]

Group of the month: hairybellies (Gastrotricha)

What is so fascinating or even better said the beauty of working with tiny worms? Many might be curious about this, when they meet researchers like me. I would suggest to look at the marvelous wonders of the hairybellies, the phylum Gastrotricha, and you will understand why it […]

GNATHOSTOMULIDA, AN OBSCURE AND OFTEN NEGLECTED PHYLUM

Gnathostomuida, also known as “lesser jaw worms”, is a phylum of about 100 described species of minute marine worms. The first gnathostomulid was discovered in 1928, in the fine sand of Kiel (Germany), by Adolf Remane. Later, Riedl (1969) elevated the animal group to the rank of phylum. […]

Field Trip to Roscoff

By Alberto Valero-Gracia In this blog post I will briefly comment about our first field trip outside Norway, a trip done to sample at the Station Biologique de Roscoff (France). During this trip (3rd – 17th of September, 2021), my supervisor, Prof. Torsten Struck, and I, were able […]

Science From Lockdown: Advent Calendar December 4th 2021

So we’re in advent again! I arrived last December to a chilly Oslo, and it feels like the year has flown by. For us, and I imagine for many of our readers too, the year has been characterised by rolling lockdowns and the steady pace towards vaccination. But […]

Biodiversity research in the Genomics era

Sequencing technology has changed in research in biology tremendously and probably much more than any other technology before. The development from radioactivity-based to nowadays single-molecule real-time sequencing of tens of thousands of base pairs in a single go in the last three decades is on par with the […]
