The hidden invasion along the Norwegian coast

Last week Line Willersrud, a Master student in our group, successfully defended her Master thesis “Assessing genetic biodiversity in Caprellidae”. She worked very hard for her thesis by collecting caprellid species along the Norwegian coast as part of the Artsdatabanken project “Assessing biodiversity in the marine algae belt“, […]

Doing genomic research with a masonry trowel

When you think about genomic research and sequencing genomes like it is the goal of the Earth Biogenome Project (EBP), Biodiversity Genomics Europe (BGE) or InvertOmics you have in mind all these new fancy technologies called Next-Generation, Third-generation or High-through-put sequencing. All these amazing advances in technologies allowing […]

The importance of the small stuff for science

Yesterday, we published an preprint on the meiofauna and why it is important to study them and which scientific questions should be addressed next. The publication involved 42 researchers from 44 institutions all around the world. The research was initiated and led by Alejandro Martínez and Diego Fontaneto […]

Teaching about sea squirts, worms and skeleton shrimps in Drøbak

As part of the ArtsDatabanken project “Assessing biodiversity in the marine algae belt“, we taught a class of eager students and consultants about the species of our project. The course did not only comprise theoretical lectures, but really hands-on experience. We went out to different spots in Drøbak […]

Group of the month: Hydrozoa

This month at the blog, we wish to present Hydroza, which is a class found within phylum Cnidaria. This lesser-known taxa is perhaps more known than thought, as well-known species like Portuguese man-o-wars (Physalia physalis), the freshwater genus Hydra, fire coral (Milleporidae), and by-the-wind sailors (Velella velella). Also, […]

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 […]

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 […]

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: Parergodrilidae (Annelida)

This month’s ”Group of the month” is a bit of shameless self-promotion. I will present an animal group today, where we conduct quite a lot of research on. However, it is nonetheless really interesting and worth to learn more about it. The family Parergodrilidae belongs to the annelids […]

Door 19: A mysterious crustacean

For my second entry in our advent calendar, I will again present a taxonomic paper. This time it is surprisingly not about worms, but about a rather intriguing group of crustaceans, Facetotecta (Figure 1). It is a small group of about 14 species, all in the genus Hansenocaris. […]
