As commented on a previous post of this 2022 Frontiers in Evolutionary Zoology advent calendar I have decided to briefly present you three works: a research paper, a researcher interview, and a book. Today, it is the turn of posting one of my favorite scientific books of the year. At least in life […]

In recent years, there has been a new movement in biology and especially in phylogenetics, which looks at the carbon footprint of our computational analyses. It is called green computing or green phylogenetics. Especially supercomputers have a high energy demand, not only for the actual calculation, but also […]

For the 16th day of our Advent Calendar, I’d like to talk about a pre-print. I thought the results were incredibly exciting and, if the article passes peer review, I assume we’ll see it in a journal in the new year! https://www.biorxiv.org/content/10.1101/2022.07.25.501387v2.full The transition from sea to land […]

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 […]

Today, most biologists would agree that there is no objective criterion to determine the rank of a supraspecific taxon. As a result, comparing how many species different taxa of the same rank include does not make much sense. Yet we keep doing it. Following that tradition we may […]

Author: Rita Austin (former group member) Diverse museum holdings offer unique and exciting potential sources of ancient DNA and other biomolecules (e.g., RNA and proteins). As technology and methods advance, the accessibility and potential for success of ancient DNA has also increased; alongside the attainment of ancient DNA […]

Currently, the UN Biodiversity Conference (COP15) is going on in Montreal, Canada. Again a COP soon after an earlier COP, namely the UN Climate Change Conference (COP27) has been held in November in Sharm-El-Sheick, Egypt. For many of us, including myself, the twin crises of climate change and […]

Today, I would like to present to the paper by Tianzhu Xiong and James Mallet about “On the impermanence of species: The collapse of genetic incompatibilities in hybridizing populations” in Evolution. The topic of the paper is not my area of research, which are deep level phylogeny, evolutionary […]

On the 10th Day of Advent, we open the door on our calendar to a paper that brought me more than a little bit of joy to read earlier this year, Yoshida et al’s “Time-series transcriptomic screening of factors contributing to the cross-tolerance to UV radiation and anhydrobiosis […]

The arthropod subphylum of Chelicerata are made up of three classes containing extant orders: Pycnogonida (Pantopoda: the sea spiders), Merostomata (Xiphosura: the horseshoe crabs) and the diverse class of Arachnida. Although the relationships between these three have proven difficult to untangle, the historical perception of arachnid monophyly has […]

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 […]

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 […]

For the 6th day of our Journal Review Advent Calendar, I wanted to present Jesus Lozano-Fernandez’s brilliant “A Practical Guide to Design and Assess a Phylogenetic Study”. I think reviews like this are really important – whether you’re trying to grasp a new kind of analysis for research, […]

Published in October, startling results of natural selection in humans indicates certain immunity genes may have helped people survive the Black Death of the 1346-1350. Caused by the bacterium Yersinia pestis, bubonic plague has swept across the globe (as pandemics) numerous times over the centuries, resulting in untold […]

When floods are mentioned, what first comes to mind is a disastrous catastrophe wrecking houses, devastating crops and, occasionally, even costing human lives. Yet, what may be a bad news for an average human could be a strike of luck for a beetle collector. Imagine flood water covering […]

The answer to this question may lay in the paper I am presenting today and at some level genomes seem to be very stable. It was probably one of the most discussed papers at the museum this year. It was the topic of several journal clubs and shows […]

Although I am working almost exclusively with marine invertebrates, one of my favourite papers this year was about birds. Hughes et al. (2022) set a quite ambitious goal: to test whether the loss of species threatened with extinction could lead to morphological and phylogenetic homogenization across the entire […]

Although frequently neglected, animals and fungi share a close evolutionary relationship. Despite the huge differences in morphology, ecology, life history and behaviour they represent the two major lineages within Opisthokonta, a clade that was earlier referred to as the “Fungi/Metazoa group” in the Tree of Life. You may […]

Text and pictures by Maël Grosse Among all the worm-like animals in the sea, polychaetes, or bristle worms, are probably the most diverse and striking group. This month is the opportunity to look at one of the most beautiful group of polychaetes (Fig. 1), the family Terebellidae Johnston, […]

Today, our paper about Perinereis species from the intertidal coasts of the Red Sea, Gulf of Suez and Suez Canal lead by Asmaa Haris Elgetany was published in ZooKeys. It is her third paper from her internship at our group and fittingly we are describing three new species […]

By now it is already a good tradition for the FEZ group at the Natural History Museum Oslo to provide in December an advent calendar blog. In previous years, the focus was on our own research and scientific output. This year we thought to take a different approach. […]

Suddenly it’s already November, so let us introduce another cool animal in the FEZ blog. This time you can learn about an enigmatic little-known group: the acoels. Acoela is an order of tiny flattened unsegmented worms, belonging to the phylum Xenacoelomorpha (pronounced “zenacelomorpha”). They live mainly in benthic […]

Spiders, insects and even more so worms and wormlike invertebrates are often considered ugly and disgusting, at least unappealing, and sometimes even dangerous. Certainly, there is also beautiful invertebrates such as e.g., butterflies, beetles, dragonflies, or some sea slugs, but usually invertebrates appeal little to our understanding of […]

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 […]

After two years of hard work and many meetings, we can officially announce that the Biodiversity Genomics Europe consortium has started this month. The road to this consortium at the European level started actually from two points. It is a collaboration between two of the most ambitious biological […]
