Månedens gruppe: Protodrilidae – fra to til flere i ett strøk

Den neste annelidgruppen som er en del av MeioSkag-prosjektet vi skal utforske er familien Protodrilidae med minst 36 arter. Det er et fint eksempel på hvor viktige molekylære data er, ikke bare for å forstå deres evolusjon, men også deres taksonomi. Taksonomi er en av de eldste biologiske […]

Group of the month: Protodrilidae – from two to several in one stroke

The next annelid group that is part of the MeioSkag project we will explore is the family Protodrilidae with at least 36 species. It is a nice example on how important molecular data are in not only understanding their evolution but also their taxonomy. Taxonomy is one of […]

Månedens gruppe – Saccocirridae, de store små

Saccocirridae regnes som en meiofaunal eller interstitiell annelidfamilie, ettersom alle artene finnes i rommet mellom sandkornene. Mens noen få arter kan være ganske små med 3 mm, er flere ganske store med opptil 3 cm i lengde. I tillegg kan de være ganske brede med en kroppsbredde på […]

Group of the month – Saccocirridae, the large small ones

Saccocirridae is considered a meiofaunal or interstitial annelid family as all species are found in the space between the sand grains. While a few species might be quite small with 3 mm, several are quite large with up to 3 cm in length. Additionally, they can be quite […]

Group of the month: Protodriloidae – just two species, but important

Protodriloidae is a family of only two species in the genus Protodriloides. Together, with the families Saccocirridae and Protodrilidae, they are part of the order Protodrilida. We will learn more about the other two families in the next two months. Hence, look forward to it. Both Protodriloides species […]

Månedens gruppe: Protodriloidae – bare to arter, men viktige

Protodriloidae er en familie med bare to arter i slekten Protodriloides. Sammen med familiene Saccocirridae og Protodrilidae er de en del av ordenen Protodrilida. Vi vil lære mer om de to andre familiene i løpet av de neste to månedene. Så gled dere til det. Begge Protodriloides-artene ser […]

Group of the month: Polygordiidae – the shiny knot worms

The next interstitial annelid family, I would like to present to you are the polygordiids. Even though these worms are part of our MeioSkag project investigating meiofaunal species in the Skagerrak, they are not truly meiofauna as their body length ranges from 1-10 cm. Hence, they are quite […]

Månedens gruppe: Polygordiidae – de skinnende knutmark

Den neste interstitielle annelidfamilien jeg vil presentere for dere, er polygordiidene. Selv om disse markene er en del av MeioSkag-prosjektet vårt, som undersøker meiofauna-arter i Skagerrak, er de ikke egentlig meiofauna, da kroppslengden deres varierer fra 1 til 10 cm. De er altså ganske store. Men fordi de […]

Door 18: The Gift That Takes a Year: The Quiet Story Behind Chinese Cordyceps

Written by Hilda Jakin Osei-Mireku What a “zombie fungus” and a ghost moth larva can teach us about patience, transformation, and waiting during Advent Advent is a season of waiting, anticipation, and preparation. While many of us count down the days to Christmas, high in regions such as […]

Door13: Suez Canal, why a one-way road?

If you look at the world today, it is impossible to ignore how deeply humans have reshaped it. We have turned forests into deserts and deserts into parks. We have warmed the atmosphere, melted ice sheets, and yet many still insist climate change is just a myth. Part […]

Door 12: Is AI the solution to overcome the challenges in sequencing genomes?

In 2018, Lewin et al proposed the ambitious goal to sequence a reference genome of each eukaryotic species on Earth within 10 years called the moonshot of biology. This proposal let to the establishment of the Earth Biogenome Project (EBP) and gained a lot of traction and momentum […]

Dør 12: Er KI løsningen for å overvinne utfordringene ved sekvensering av genomer?

I 2018 foreslo Lewin et al det ambisiøse målet å sekvensere et referansegenom for hver eukaryotisk art på jorden innen 10 år, kalt «moonshot of biology». Dette forslaget førte til etableringen av Earth Biogenome Project (EBP), som fikk stor oppmerksomhet og fart i etterkant. Dette førte til etableringen […]

Door 5: Horsetail (Equisetum) species still hybridise, 100 million years after they diverged

In a previous blogpost, I asked the question how long species are able to form hybrids after their lineages diverged — and I showed that certain species of flowering plants (angiosperms) retain this ability for at least 50 million years (Ma). This question is of particular significance because […]

Group of the month: The unusual interstitial annelids – Nerillidae

As part of our new ArtsDatabanken project MeioSkag, we are investigating interstitial and meiofaunal species occurring in sediments of the Norwegian part of the Skagerrak. Among others, this includes the so-called interstitial families within Annelida. In this series “Group of the month”, I will now present the different […]

Månedens gruppe: De uvanlige interstitielle leddmarkene – Nerillidae

Som en del av vårt nye ArtsDatabanken-prosjekt MeioSkag undersøker vi interstitielle og meiofauna arter som forekommer i sedimenter i den norske delen av Skagerrak. Dette omfatter blant annet de såkalte interstitielle familiene innenfor Annelida. I denne serien «Månedens gruppe» vil jeg nå presentere de ulike familiene som ikke […]

The second of its kind – reference genome of a lamp shall

A couple of days ago we published the genome of a brachiopod species, in specific Discradisca antillarum in the journal G3. Brachiopods are a group of shelled, filter-feeding marine invertebrates also known as lamp shalls. Though they superficially resemble bivalve mollusks, brachiopods are not. Brachiopods have the shells […]

Den andre i sitt slag – referansegenomet til en armfoting

For et par dager siden publiserte vi genomet til en armfotinger, nærmere bestemt Discradisca antillarum, i tidsskriftet G3. Brakiopoder er en gruppe skallede, filterfôrende marine virvelløse dyr, også kjent som armfotinger. Selv om de overfladisk ligner på muslinger, er brakiopoder ikke det. Brakiopoder har skall på rygg- og […]

Yet another Artsdatabanken project successfully finished

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 […]

Nok et Artsdatabanken-prosjekt vellykket fullført

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. […]

Vermetids, the laziest: Snails Who Gave Up Crawling

We all know a worm. We all know a snail. Or at least, we think we do.But nature often blurs the lines we draw so confidently. In the case of vermetid snails, also known as “worm snails,” appearances can be deceiving. These creatures look like worms but are, […]

Den ukjente biologiske mangfoldigheten av annelider i europeiske farvann – en fallstudie av cirratulider

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 […]

Group of the month, August: Rough sharks (Genus Oxynotus)

Drawing a shark could be fun, so why not following a step-by-step tutorial for it? As many suggest, let`s start by deconstruct your soon to be shark in simple geometrical figures. A triangle can be the head, a dorsal fin or a tail. One or two rectangles for […]

Group of the months: The nicking worms (Kamptozoa or Entoprocta)

The phylum Entoprocta (also called Kamptozoa) are known as the nicking worm. Globally, 260 species are known to date and 30 in Norway. The individuals are small with a body size of 0.5 – 7 mm. However, besides solitary species, other species build colonies and these can be […]

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 […]
