Group of the Month March: Laboulbeniales
Let me introduce you to the Group of the Month for March: A fungus! At this point you are probably thinking to yourself: “Wait a minute, that’s not a fungus. That’s clearly just a beetle…” And for the most part, you’d be right! Let’s zoom in a bit […]

Månedens Gruppe Mars: Laboulbeniales
La meg presentere månedens gruppe for mars: En sopp! Nå tenker du sikkert for deg selv: «Vent, det der er ikke en sopp. Det er helt klart bare en bille…» Og det er i og for seg riktig! La oss zoome litt lengre inn: Tankerekken fortsetter: «Hmm… Det […]

Group of the month: Cycliophora – the ringbearers and the “Norwegian” phylum
This month I will present to you a very small phylum of animals – both in size and in number of species. The phylum Cycliophora, which means the ring-bearer, comprises exactly one genus and two described species. These species are about 350 µm in body length, which is […]

Månedens gruppe: Cycliophora – ringbærerne og den «norske» fylumet
Denne måneden vil jeg presentere en svært liten dyregruppe – både i størrelse og i antall arter. Cycliophora, som betyr ringbærer, består av nøyaktig én slekt og to beskrevne arter. Disse artene er ca. 350 µm i kroppslengde, noe som er mindre enn en halv millimeter og omtrent […]

Group of the Month: Tree ferns – an Australian holiday discovery
A visit to the Adelaide Botanic Garden is certainly high up on the to-do list of a biologist visiting the capital of South Australia. In December 2024, a couple of days before the Australian midsummer, I had the pleasure to visit the Adelaide Botanic Garden and explored the […]

Christmas in the Ocean: The Marvel of Christmas Tree Worms
Today, I want to introduce a fascinating group of worms that are particularly relevant during the Christmas season. Known as Christmas tree worms, these marine annelids belong to the family Serpulidae. They are renowned for their radiolar crowns and their habit of dwelling within calcareous tubes attached on […]

Picture from Galindo et al. 2018, https://doi.org/10.1093/gbe/evy205 For this month’s group, I want to present you another group of organisms I am currently working with in my postdoc project PolyPro3 here at NHM Oslo. This is […]

Group of the month September– Viola
This month I wish to present a group that I have been working on for nearly 30 years, the angiosperm genus Viola which comprises violets and pansies (Figure 1). Our group recently produced a monograph of the genus (Marcussen et al. 2022) – the first comprehensive (and very […]

Group of the month: The boring worms
This month, we will present to you the boring worms. These are worms of different genera, which belong to the polychaete family Spionidae. Polychaetes are also called bristle worms as the often have a large number (poly) of bristles (chaetae) on their segments. The family Spionidae is a […]

Månedens gruppe: De “boring” ormene
Denne måneden vil vi presentere de “boring” ormene. Dette er ormer av forskjellige slekter, som tilhører polychaete-familien Spionidae. Polychaeter kalles også flerbørstemarker, ettersom de ofte har et stort antall (poly) børster (chaetae) på segmentene sine. Familien Spionidae er en familie som omfatter mer enn 600 arter i mer […]
