Annelida, or segmented worms, is a vast and diverse group of metazoans of over 20000 species that includes, amongst others, earthworms, leeches, echiurids, sipunculids and polychaetes. With over 300 species the polychaete family Cirratulidae is one of the most species-rich and common in benthic assemblages in a variety […]

Annelida, eller segmenterte ormer, er en stor og mangfoldig gruppe av metazoer med over 20 000 arter, som blant annet omfatter meitemark, igler, echiurider, sipunculider og polychaeter. Med over 300 arter er polychaete-familien Cirratulidae en av de mest artsrike og vanlige i bentiske samfunn i en rekke habitater. […]

The marine biodiversity of Europe is generally considered well known comparison to other regions, especially of the global South. However, also in European waters, some habitats and regions have been scarcely studied and many species could remain to be discovered and described. This has been shown, for example, […]

Den marine biologiske mangfoldigheten i Europa anses generelt å være godt kjent sammenlignet med andre regioner, spesielt i den globale sørlige halvkule. Imidlertid er også i europeiske farvann noen habitater og regioner knapt studert, og mange arter kan fortsatt være uoppdagede og ubeskrevne. Dette er for eksempel vist […]

Tidligere i år fikk gruppen vår finansiert et nytt Artsprosjekt. Så la oss dykke ned i meiofaunaens verden. En stor del av det biologiske mangfoldet i havet finnes i rommet mellom sandkornene, grusen og steinene i sedimentene. Arter som lever her, også kjent som meiofauna, utgjør et avgjørende […]

Earlier this year, our group got a new Artsprosjekt funded. So, let’s dive into the world of meiofauna. A substantial part of marine biodiversity occurs in the space between the sand grains, gravel and stones of sediments. Species that live here, also known as meiofauna, comprise a crucial […]

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 […]

Som vi skrev i forrige blogg i adventskalenderen, hadde vi mange endringer allerede i fjor, med ny gruppeleder og en ny nettside, som vi skal videreutvikle i år. En annen endring som trer i kraft i år, er at vi skifter navn på gruppen vår og for første […]

Last week Line Willersrud, a Master student in our group, successfully defended her Master thesis “Assessing genetic biodiversity in Caprellidae”. She worked very hard for her thesis by collecting caprellid species along the Norwegian coast as part of the Artsdatabanken project “Assessing biodiversity in the marine algae belt“, […]

As part of the ArtsDatabanken project “Assessing biodiversity in the marine algae belt“, we taught a class of eager students and consultants about the species of our project. The course did not only comprise theoretical lectures, but really hands-on experience. We went out to different spots in Drøbak […]

Summer is here, so it’s time for the Artsdatabanken project team to go back to the field. Or to the sea, in our case. After driving 500km from the east to the west coast, through beautiful mountains and majestic fjords, we arrived at Austevoll (Figure 1), an archipelago […]

After introducing the Artsdatabanken project and telling about our summer collection trips (Trøndelag and Oslo), it is time to present the six invertebrate groups that we are working with. From star ascidians to Christmas-tree worms, this seems to be the adequate time of the year to get to […]

The year 2021 was full of unexpected happenings and opportunities for both students, as in me Marianna Khodabandehlou and my fellow student, Sine Hagestad. We both were doing our last semester in our Biosciences degree and wanted to gain some hands-on experience before we began our Masters. We […]

In the last two weeks of August, the ArtsDatabanken team has came together for the first big field trip. While sadly not everyone could join, seven researchers from Oslo, Berlin and Gothenburg comprised the diverse and highly motivated group. The destination was Sletvik, a biological station in the […]

The marine algae belt comprising kelp forests, seagrass meadows and rocky reefs with coralline red seaweeds is one of the most active primary producing environments in the sea. It also harbors are great diversity of animals including sea squirts, ribbon worms, nick worms, serpulid worms, spionid worms and […]
