Here we blog about our research on cryptic species, which is at present done by PhD and Master theses.

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 […]

The taxonomic challenge of the annelid genus Perinereis (Nereididae) just gets larger
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 […]

Door 15: Cryptic species and public outreach
An essential aspect of doing research and working as a scientist is to communicate to the larger public interesting and important results. Outreach to the public is extremely important, as it creates awareness and fascination as well as it facilitates learning and understanding. For many, the topics we […]

Stygocapitella – an incredibly old worm found beneath your beach towel
Species of the genus Stygocapitella belong to the ringed worms, also known as Annelida. Annelids are worms like earthworms, lugworm or christmas tree worms, but also leeches or very tiny worms living in the spaces between the sand grains, called the interstitium. Such an interstitial group of worms […]

December 7: How are the Aegialites-beetles?
A year has passed since the last update on my project related to the Aegialites-beetles. Throughout the year, the project has moved slowly forward with some minor corona-bumps in the way. The intended fieldwork to Japan is still postponed, but trough Vladimir, we have managed to get a […]

Bad apples and a marine worm – sometimes they go together
During his PhD Jose was interested in the evolution of the cryptic species complexes in the annelid genus Stygocapitella, which occurs at sandy beaches around the world. Part of his thesis also comprised population-genomic studies to understand the underlying genomic background of morphological stasis. During the phylogenomic studies […]

What causes species not to change despite ongoing evolution?
Cryptic species have for long time been considered as purely a taxonomical challenge. However, in the last decade it has been shown that their recognition has also consequences for several other biological disciplines. Recently, their importance for understanding certain evolutionary processes has been highlighted. Most prominent among these […]

From the forest to the deep sea
This week a member of our group, Torsten Struck, published a review paper on the two annelid families Parergodrilidae and Orbiniidae together with Miguel Meca from the University Museum of Bergen as the first author and Anna Zhadan from the Lomonosov Moscow State University in the journal Diversity. […]

A tale of stone and ice
Our calendar is coming to its close and at the second-to-last day it features two Master projects, which started this year working with annelids, which are both completely computer-based making use of the SAGA supercomputer infrastructure through the command line, and all analytical programs used are monitored through […]

The intertidal beetle genus Aegialites
Last year, Marianne started her PhD-project in the FEZ-group. Marianne kick-started her project with a fieldtrip to the east-coast of USA to collect beetles. The beetles, which live in the cracks and crevices on rocky shores, proved to be difficult to find. With hammer and chisel, she managed […]
