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 […]

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 […]

Published in Zoologica Scripta: link here. The paper named “Insight into the phylogeny of the intertidal beetle genus Aegialites (Coleoptera, Salpingidae)“, by Marianne N. Haugen, Vladimir I. Gusarov, Derek S. Sikes & Torsten H. Struck is now published in Zoologica Scripta. This paper, which is an important part […]

In this blog post, I wish to write about species delimitation. What it is and methods we have to delimit species from each other. Species delimitation — what it is and why it matters Species delimitation is the set of methods and conceptual approaches used to determine where […]

Introduction Taxonomy is the science of classifying, naming, and describing organisms based on shared characteristics. The classification of living things, has its origins in ancient Greece and in its modern form dates back nearly 250 years, to Carl Von Linné’s Systema Naturae (1735) where Linnaeus introduced the binomial […]

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 […]

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. […]

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 […]

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 […]

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 […]

Hvorfor er denne gruppa interessant å studere?Myrfiolgruppa (Viola seksjon Plagiostigma, underseksjon Stolonosae; Violaceae) er ei av flere artergrupper i den nordlige tempererte sonen som diversifiserte som respons på global nedkjøling de siste ~5 millioner år. Å studere artene i denne gruppa gir derfor mulighet til å belyse de […]

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 […]

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 […]

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 […]

I forrige uke publiserte vi en artikkel om meiofauna og hvorfor det er viktig å studere dem, og hvilke vitenskapelige spørsmål som bør tas opp i neste omgang. Artikkelen «Fundamental questions in meiofauna research highlight how small but ubiquitous animals can improve our understanding of Nature» ble publisert […]

Last week, we published an paper on meiofauna and why it is important to study them and which scientific questions should be addressed next. The paper “Fundamental questions in meiofauna research highlight how small but ubiquitous animals can improve our understanding of Nature” was published in Communications Biology. […]

Whenever you hear the word fungi, chances are high that you are thinking of the colourful variation of mushroom fruiting bodies popping up in high abundance during the fall. Or maybe you’re thinking of the vast webs of underground mycelia that most fungi produce. For some, the frightening […]

Når du hører ordet sopp, er sjansen stor for at du tenker på den fargerike variasjonen av soppfruktlegemer som popper opp i store mengder om høsten. Eller kanskje du tenker på de enorme nettene av underjordiske mycel som de fleste sopper produserer. For noen er kanskje den skremmende […]

For most people, discovering new species seems like an extraordinary event, something that happens only once in a lifetime or at least something very rare. However, for some groups of organisms, particularly understudied ones, it’s actually very easy to come across a new species to science and perhaps […]

Human-mediated alteration and conversion of forest ecosystems cause massive changes in the species compositions of communities in affected areas. The large scale monetary incentives of deforestation, especially in threatened tropical rainforests, plays a massive role in the rapid loss of habitats and nature seen worldwide. Even in the […]

Menneskeskapte endringer og omdanning av skogøkosystemer fører til massive endringer i artssammensetningen i de berørte områdene. De storstilte økonomiske insentivene til avskoging, særlig i truet tropisk regnskog, spiller en viktig rolle i det raske tapet av habitater og natur som vi ser verden over. Selv i det langt […]

CEG har en lang tradisjon for å være vertskap for Erasmus-studenter på praksisopphold. I år hadde vi også to studenter på besøk fra Sardinia i løpet av sommeren. «Erasmus+ er EUs program for å støtte utdanning, opplæring, ungdom og idrett i Europa.» Det er et program som legger […]

CEG has a long standing tradition of hosting Erasmus students for an internship. This year we also had two students visiting us from Sardinia during the summer. “Erasmus+ is the EU’s program to support education, training, youth and sport in Europe.” It is a program that facilities knowledge […]

The recnt years have seen a hand over fist development of artificial intelligence (AI) applications, and such applications affect the daily life of scientists at an increasing pace, and the ongoing development may in the near future also modify our understanding of science in general. For biologist an […]
