Door 21: The evolution of stress related genes in parasitic flatworms

It is always a pleasure if international scientific cooperations deliver exciting results. This was the case with my cooperation with colleagues at the University Hasselt, Belgium. The study was a key component of the PhD thesis of Armando J. Cruz‑Laufer who also coordinated the drafting of the scientific […]

Door 20: Looking at the past to understand the future of Leopard Seals

Cover picture by Sue Flood Last time, I wrote about how glacial-isolation caused the divergence of a small population of ringed seals in the Ilulissat Icefjord, West Greenland. The text ended with a final consideration on the importance of developing research plan to retrieve molecular data for Arctic […]

Door 19: The genome of the flatworm model species Schmidtea mediterranea

Earlier this year in September Ivanković and colleagues published the results of a study coordinated by the research group of Jochen Rink at the Max Planck Institute for Multidisciplinary Sciences, Göttingen, Germany and presented highly improved genomes of the four planarian flatworm species from the genus Schmidtea. These […]

Door 18: Forgotten Reefs; Struggles for Survival in the Strait of Hormuz

For the next door of our Advent calendar, I’d like to take you on a journey to the Strait of Hormuz, one of the most politically significant waterways. It is located between the Persian Gulf and the Gulf of Oman in the northern Indian Ocean, and acts as […]

Door 17: Meet Finn, an adventurous zooplankton!

Hi! My name is Finn, and I’m a teen Calanus finmarchicus (proudly in my fifth copepodite stage of development!). I am honoured to open the Door 17! To be honest, I should be napping right now, like all my trillions of friends, but I’m just too excited because soon, I’ll […]

Door 16: Small creatures and studying them matters

For today’s advent calendar, I want to talk about my favourite organisms, the protists. In one of my last years advent calendar posts, I talked about their diversity and importance for ecosystem functioning and, therefore, felt like introducing this recent paper by Perrin & Dorrel (2024) fits the […]

Door 15: CEG involvement in the European BGE genome sequencing project

CEG research group members Torsten Struck and myself are coordinating the task of Community Sampling, within WP5 of the the EU-funded BioGenomics Europe project. We have now completed our task, well before the deadline of February 2025 set by BGE. Our task began with annoucing two public calls, […]

Door 14: A miracle of long distance dispersal? A wingless beetle species occurring on distant subantarctic islands

One of the most remarkable beetle species occurring in the Falkland Islands is Leptusa (Halmaeusa) atriceps (Waterhouse, 1875), presented on the photo above (photo by Orlov et al 2019). It is a small, 4 to 5 mm long, wingless beetle associated mostly with decomposing seaweed on the beach. […]

Door 13: Discovering hidden microscopic diversity in Norway

Whenever you hear the word fungi, chances are high that you are thinking of the colourful variation of mushroom fruiting bodies popping up in high abundance during the fall. Or maybe you’re thinking of the vast webs of underground mycelia that most fungi produce. For some, the frightening […]

Dør 13: Oppdag det skjulte mikroskopiske mangfoldet i Norge

Når du hører ordet sopp, er sjansen stor for at du tenker på den fargerike variasjonen av soppfruktlegemer som popper opp i store mengder om høsten. Eller kanskje du tenker på de enorme nettene av underjordiske mycel som de fleste sopper produserer. For noen er kanskje den skremmende […]
