Here all our advent calendar entries from 2024.
Category: 2024
Door 23: Struggles, Setbacks & Solutions
I’m three out of four semesters deep into an MSc, meaning that in a few short months I will be delivering a completed thesis, with detailed results and an in-depth discussion. I’ve had a timeline laid out since the very beginning and am largely on track. That isn’t […]
Door 22: Mystery bird uniting different museum groups
Following the example of Pia’s post about the gift of collaboration, I will introduce you to a side project I did with two colleagues from a different research group at today’s door. It started with a strange sighting from a friend: a bird that looked like a species […]
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 […]
Door 12: The Gift of Collaboration
It’s the holiday season, and as we know it’s a season of giving and exchange. One way I want to acknowledge a “gift” I received this year is to talk about the importance of collaboration and free exchange of knowledge and information. I’m currently working on my Master’s […]
Door 11: Finding new species to Norway – how easy can it be?
For most people, discovering new species seems like an extraordinary event, something that happens only once in a lifetime or at least something very rare. However, for some groups of organisms, particularly understudied ones, it’s actually very easy to come across a new species to science and perhaps […]
Door 10: Habitat fragmentation shaping the beetle communities of African mountains
Human-mediated alteration and conversion of forest ecosystems cause massive changes in the species compositions of communities in affected areas. The large scale monetary incentives of deforestation, especially in threatened tropical rainforests, plays a massive role in the rapid loss of habitats and nature seen worldwide. Even in the […]
Dør 10: Fragmentering av habitater former billesamfunnene i afrikanske fjell
Menneskeskapte endringer og omdanning av skogøkosystemer fører til massive endringer i artssammensetningen i de berørte områdene. De storstilte økonomiske insentivene til avskoging, særlig i truet tropisk regnskog, spiller en viktig rolle i det raske tapet av habitater og natur som vi ser verden over. Selv i det langt […]
Door 9: Divergence by isolation in Marine Mammals – the case of Kangia ringed seals
Cover: Picture by Greenland Institute of Natural Resources When I need to take a break from work, I often stroll around the Oslo Natural History Museum. Zoological collections have always fascinated me since I was a child, and now that I work for one of them I`m able […]
Door 8: Erasmus – exchange of knowledge across Europe
CEG has a long standing tradition of hosting Erasmus students for an internship. This year we also had two students visiting us from Sardinia during the summer. “Erasmus+ is the EU’s program to support education, training, youth and sport in Europe.” It is a program that facilities knowledge […]
Dør 8: Erasmus – utveksling av kunnskap på tvers av Europa
CEG har en lang tradisjon for å være vertskap for Erasmus-studenter på praksisopphold. I år hadde vi også to studenter på besøk fra Sardinia i løpet av sommeren. «Erasmus+ er EUs program for å støtte utdanning, opplæring, ungdom og idrett i Europa.» Det er et program som legger […]
Door 7: A New Perspective on Human Origins, interconnected Lineages in Africa
Species evolution is often depicted as linear, neatly separated branches of a tree, an oversimplification that fails to capture the true complexity of evolutionary history. This is especially true for human evolution, where the prevailing belief has been that the modern human population that emerged from Africa was […]
Door 6: Tiny Zooplankton with Giant Genetic Mysteries
For our 6th door, I want to introduce you to a puzzling aspect of my favorite study organism, Calanus—a group of tiny marine zooplankton that play a crucial role in the North Atlantic and Arctic ecosystems. These crustaceans, no larger than a grain of rice, sustain our oceans and […]
Door 5: To sample or not to sample? – winter sampling for benthic marine invertebrates
In CEG group, we collect samples from the nature for various projects such as MeioSkag and PolyPro3 (marine invertebrates) and ANTENNA (insects). Here in the Northern Europe the best season for sampling usually is in the summer, or one might travel to an exotic location to find specific […]
Door 4: For how long can species retain the ability to form hybrids?
All the biodiversity on our planet has originated through a series of speciation events. Speciation occurs when two lineages cease interbreeding, for one reason or another, but even after speciation the new species commonly retain the ability to hybridise for a while. Soon after speciation, the species genomes […]
