Slimete, men skinnende – det første genomet på referansenivå fra InvertOmics-prosjektet

Vi er glade for å kunne kunngjøre den første genomutgivelsen fra InvertOmics-prosjektet i Genome Biology and Evolution. Genomet til Emplectonema gracile har blitt sekvensert og generert på referansenivået til EBP-standardene. Hva betyr dette? Kvaliteten på genomet er av så høy kvalitet at det kan brukes som referanse for […]

Månedens gruppe: Loricifera

I månedens gruppe i april tar vi for oss en hel fyla!Loricifera er en av de nyere gruppene, og ble først oppdaget i 1983. Siden den gang har 44 arter blitt navngitt, fra Frankrike til Antarktis og Japan, og flere oppdages hvert år. Jeg skrev en artikkel om […]

Group of the month: Dinophilidae

The group of the month I would like to introduce to you today is a group I have a close personal connection with. The group goes back a long way with me. I will present you the annelid family Dinophilidae. After my Diploma thesis (today Master thesis) on […]

Månedens gruppe: Dinophilidae

Månedens gruppe jeg vil presentere for dere i dag, er en gruppe jeg har et nært personlig forhold til. Gruppen har en lang historie for meg. Jeg vil presentere familien til Annelida Dinophilidae. Etter å ha skrevet diplomoppgave (i dag masteroppgave) om proteiner i et virus relatert til […]

Door 21: Wonderful world of symbioses and a note on conserving biodiversity

Only three days until Christmas! For my final post in the advent calendar, I want to introduce our readers to an essential and complex phenomenon in nature, symbiosis. In our daily language, we might casually refer to symbiosis as a mutually beneficial relationship. However, in ecological terms, symbiosis […]

Day 20: Defending Against Rising Ocean Acidification

As we open the door on day 20, we look at a species in the Invertomics study category in the wild, and highlight a study from 2019 that places Platynereis in a modern context, to assess its capability to act as a model organism for studies of ocean […]

Day 15: What’s coming next year!

December is a time to reflect on the year that has passed, both the happy and sad, the success and the failures. But it’s also a time to look forward to the year ahead, new possibilities and opportunities. For me, this is especially important, as next time December […]

Day 14: When is a Larva like a Birthday Present?

For my second advent calendar entry this year, I would like to highlight one of the most exciting papers I’ve read recently. It came out just last month in Organisms Diversity & Evolution, and is titled “A new Loriciferan, Scaberiloricus samba gen. et sp. nov., links the Higgins larva and […]

Door 9: Conservation of parasite biodiversity

Conservation of biodiversity is increasingly recognized as an important challenge, and numerous reports have addressed the ongoing loss of biodiversity and pinpointed the potential consequences. Even a sixth, man-induced mass extinction has been intensively discussed (e.g., https://www.nhm.ac.uk/discover/what-is-mass-extinction-and-are-we-facing-a-sixth-one.html). Frequently, the focus of such discussions is on endangered iconic species […]

Door 6: Biodiversity, Conservation, and Sticking Up For The Little Guy

For this year’s Advent Calendar, we’ve decided to theme ourselves around climate change and conservation. For my first blog entry, I’ve decided to write more of a background about the general need for marine biodiversity conservation, and some opinions on who should care, and why. I will then […]

Door 5: A book (gift) recommendation

As the festive season approaches, many of us find ourselves pondering the perfect gifts for our loved ones. Is for this reason that, in this post, I’d like to suggest a unique present that transcends the boundaries between scientific and non-scientific interests—a coffee table book titled “The Art […]

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. […]

Door 15: Improving marine biodiversity assessments by sampling larvae

Another paper I really enjoyed reading this year was “Sampling multiple life stages significantly increases estimates of marine biodiversity”, published last April by Svetlana Maslakova and her colleagues. They argue that most surveys of marine life underestimate the total number of species because they rely almost entirely on […]

Door 7: New day, new species

One of my favourite papers this year is, logically, about two of my favourite topics: taxonomy and worms. In this paper, Lavesque et al. revise the family Terebellidae sensu stricto (a part of the spaghetti worms I presented in a previous blog post) in French waters. They review […]
