The marsh violets – a lineage where hybridisation creates, modifies and deletes diversity
Why is this group interesting to study? The marsh violet group (Viola sect. Plagiostigma, subsect. Stolonosae, in part; Violaceae) is one of numerous north-temperate species groups that diversified in response to climate cooling in the last ~5 million years. Thus, studying this group has the potential to elucidate […]
New year – new name; FEZ is now CEG
As written in our last blog of the advent calendar, we had many changes already last year with a new group leader and a new group webpage, which we is still develop further this year. However, another change becoming effective this year is that we change the name […]
Door 22: De-extinction
When in 1990 the fascinating novel entitled ‘Jurassic Park’ by Michael Crichton was published the idea of a re-creation of extinct species was pure fiction. Certainly, by the time many of us were wondering if de-extinction may become reality, even more so when in 1993 the Steven Spielberg […]
Raising the treasure of the collections for barcoding
The Biodiversity Genomic Europe (BGE) project has three streams dealing with the biodiversity crisis. In the blog so far, we have mostly presented about one stream, the European Reference Genome Atlas (ERGA) one concentrating on the genomic side of the project. However, another stream is concentrating on the […]

Door 5: Immunity Genes Related to the Black Death
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 […]
Specimen fixation – how, and what for(malin)?
When an organism dies, it decomposes, whereby complex structures are broken down. Broadly following 5 to 6 stages, decomposition may be halted or accelerated at any point depending on conditions, such as temperature, water, and oxygen, resulting in different morphological and chemical changes to the organism. By chance, […]
Group of the month: Phylum Chordata, subphylum Tunicata (Previously Urochordata)
Written by Line Willersrud and Rita M. Austin The phylum Chordata contains the three subphylums, Tunicata, Cephalochordata and Vertebrata. Vertebrata, which includes humans and all other mammals, birds, fishes, amphibians and reptiles, are differentiated from other chordates by having an enclosed vertebral column, the backbone. But inclusion in […]

Group of the month: Family Caprellidae
Spooky scary skeleton shrimp, send shivers down your spine, their appearance will shock your soul, but certainly don’t seal your doom tonight! Family Caprellidea, otherwise known as skeleton shrimp, are small marine arthropods that are found world-wide. Using their specialized ‘feet’, called pereopods, these slender, segmented invertebrates cling […]
Animal of the month: Cystophora cristata
By Pia Merete Eriksen and Rita M. Austin I think most of us conceptualize a seal as a comical or cute animal, darting through open waters – I don’t think many of us envisage blood-red balloons and bulging sacs, specialized for a ritual of dominance and mating. Enter, […]
Catching up! Door 22 – Progresses and challenges during 2021
Everyone has missed a day of ticking off advent as some point! Making today a two-for-one post day! Enjoy! By Alberto Valero-Gracia This year has been a bit peculiar for most of us. However, as with most of our colleagues at the NHM, the FEZ group has always […]
Door 21 – Persistent considerations for molecular analyses of museum specimens
Many factors come into play when making decisions about using museum specimens, especially for molecular applications. As a museum scientist that utilizes molecular methodologies, I am constantly conducting experiments in my mind to try to run through how each step and/or technique will (or won’t) get me to […]
Door 13: Christmas Excitement at the Museum
“On the thirteenth day of Christmas my true love gave to me”…an unbridled curiosity of organismal diversity and their relationships, historical contexts, and the natural world that has directly informed my career. Me too! While my fascination of the natural world isn’t directly related to the holidays, I […]
