We are destroying species' habitats, leading to a mass extinction event. This habitat destruction also reduces the genetic diversity _within_ species. Our latest work develops quantitative models to predict how much genetic diversity has been and _will be_ lost. 🧬🧪🧵 www.pnas.org/doi/10.1073/...

So cool to see our paper finally out! Thanks to a fantastic team of co-authors 🐟🧬 @biovitenskap.bsky.social @unioslo-cees.bsky.social

Finally is the paper where we present the unique genomic architectures of the Arctic codfishes out!! Nice work by @gadus-sivus.bsky.social and co-authors … @biovitenskap.bsky.social @unioslo-cees.bsky.social link.springer.com/article/10.1...

New results on Littorina fabalis ecotypes! 🐌 Inversions aren't just enabling parallel adaptation to wave exposure in France & Sweden, they're also hotspots for site-specific differences, including a striking color QTL associated with one inversion but only in France. www.biorxiv.org/content/10.6...

1/9 New in @science.org www.science.org/doi/10.1126/science.ado8005 How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

Super happy to see our paper out! Reference choice matters, especially if you work with species that has lots of chromosomal rearrangements 🧬🐟

New paper out where we demonstrate how pop gen parameters and scoring of structural variants (inversions) could be affected by the choice of reference genome (both in terms of both quality and relatedness). @unioslo-cees.bsky.social @biovitenskap.bsky.social link.springer.com/article/10.1...

Breaking genetics news‼️🌱🌽 A natural DNA trick triples recombination in maize. What we first saw in Arabidopsis (@hendersi lab) a decade ago is now confirmed in crops—opening new doors for plant breeding. Published today in Nature Plants! More details 👉 www.nature.com/articles/s41...

Høyt fiskepress har endret alder for kjønnsmodning og genetisk sammensetning hos Barents-torsken, som er verdens største gjenværende torskebestand. Også på Grand Banks gikk gytealderen ned før kollapsen var et faktum www.forskning.no/dna-fisk-hav...

Regjeringen gir 1 milliard kroner til polarforskning og forskningsprosjektet #Polarhavet2050, hvor Universitetet i Oslo er én av fjorten partnere. Dette blir spennende! @jentoft.bsky.social

Out after peer review, collaborative study from Nordborg & Weigel labs with help from many others. Not the largest collection of new Arabidopsis thaliana genomes, but we hopefully put forward some good ideas for how to think about pangenomes and their analysis! www.nature.com/articles/s41...

I flere tiår har det vært debattert om vi mennesker påvirker genene til bestandene vi høster. I ett nytt studie - hvor vi har fått tilgang på over hundre år gamle prøver av skrei samlet inn i Lofoten - avdekker nettopp dette!! For mere info se: www.titan.uio.no/naturvitensk...

Utrolig at Forsvarsdepartementet prøver å benekte helt klare fakta: Reisetid ER tillagt vekt, og utgjør avgjørende faktor i lokaliseringsvurderingen. Uten å vekte reisetid, eller vekte annerledes, kommer andre alternativer enn Hurum bedre ut. Det må man stå for. borsen.dagbladet.no/nyheter/giga...

Forsvarsdepartementet hevder nye rapporter viser at Hurum er beste sted for ny sprengstoff-fabrikk. Det viser seg at flere andre plasseringer kommer klart bedre ut, dersom man ikke vekter «nærhet til eksisterende fabrikk» som dynamisk kriterie. Troverdig prosess? www.budstikka.no/det-er-bedre...

For få år siden var det en tredje torskebestand i Oslofjorden Nå er den borte. Forskere fra @biovitenskap.bsky.social advarer om pågående kollaps av de lokale torskebestandene @jentoft.bsky.social #Titan www.titan.uio.no/livsvitenska...

Takk til Dagbladet og Titan som fronter saken: Har sagt det før og sier det igjen: Oslofjorden er i dyp krise! Det har gått alt for langt og vi har ingen tid å miste! www.dagbladet.no/nyheter/rope...

Haster det for Oslofjorden nå? Ja. Hva skjer om regjeringa ikke snarest kommer med kraftfulle nok nullfiskeområder, i tråd med faglige anbefalinger og et stort flertall i befolkningen sitt ønske? Utryddelse av Oslofjordtorsk på det politiske rullebladet, værsågod.

En fjord i tre ulike stadier, vil du se? Tråd, ja. Fra beryktede Viksfjorden, Larvik, Ytre Oslofjord, i dag. 1. Litt friskt, fint sjøgress på enkelte plasser. Dette er kystsonens "regnskog". Kan huse et mangfold av store og små dyr.

Oppdrett slipper ut like mye fosfor og nitrogen langs norskekysten som 40–60 millioner mennesker. I mange fjorder er det den største utslippskilden. Men kun kommunale avløp, altså deg og meg, blir pålagt dyre rensekrav. Er det riktig? Kommunal Rapport løfter nå dette i en artikkelserie. Her første:

Bra fra @uneaba.bsky.social om Chemring Nobel og Regjeringen sine planer for økt sprengstoffproduksjon ved Oslofjorden: -Vil nitrogenutslippene til fjorden øke? Hvor mye? - For tidlig å si noe om dette nå, sier departementet. Det er feil svar. Riktig svar er at fjorden ikke tåler nye utslipp.

For those interested in the evolution of phenotypic plasticity - Shen Tian et al. found that a novel bit of DNA - a Hox gene promoter in the genome of satyrid butterflies - boosts plasticity in the size of their eyespots in response to temperature. www.biorxiv.org/content/10.1...

This was quite a beautiful paper--definitely a must-read for folks that want to do these kinds of comparisons

MDG krever at fabrikken bygges et annet sted, og mener utslippene vil være uansvarlige og respektløse overfor lokalsamfunnet. Les saken med @uneaba.bsky.social

High-elevation species often show faster mitochondrial evolution - Iverson et al. study 700+ species, finding that higher dN/dS at altitude is likely due to relaxed selection from smaller ranges and reduced pop. sizes, not positive selection. 🔗 doi.org/10.1093/molb... #evobio #molbio #altitude

The rest of Mendel's alleles characterized! So, out of 7 traits, 3 caused by TE insertions!!! (though apparently there are two different green alleles, one cause by a TE insertion, but another a promoter deletion allele) www.nature.com/articles/s41...

“Between firing experts at NOAA, delaying fishing seasons, and disrupting ocean science and data collection, the Trump Administration is causing unprecedented chaos. Today’s Executive Order would weaken, not strengthen, our fishing industry.” 🧪🦑🌎🐠

President Trump on Thursday said he was allowing commercial fishing in one of the world’s largest ocean reserves, introducing industrial operations for the first time in more than a decade to a vast area of the Pacific dotted with coral atolls and populated by endangered sea turtles and whales.

Bemerkelsesverdig ansamling av tidligere fiskeriforskere som har svømmet inn i et nytt habitat for å hevde at: 1. Oslofjorden er syk uansett. 2. Marint vern vil ikke virke. 3. Bunntråling er helt OK. I toppen kunne de også nevnt at de har rådgitt staten mens Oslofjorden kollapset, kanskje?

We have a #PhD opening on #DNA- based exploration of #shark and #ray #biodiversity in #indonesian fisheries! @sharkscience.bsky.social @misselasmo.bsky.social @dhikafishery.bsky.social @joanna-m-murray.bsky.social www.findaphd.com/phds/project...

The ocean is the heart of our life support system, absorbing over 90% of the excess heat from global warming. This is evident in the rise of ocean heat content over time.

NEW: Entire scientific fields have been wiped out by the nearly 800 grants cancelled at NIH, finds a @nature.com analysis of the unprecedented cuts. About half of all 2024 NIH projects related to LGBT+ health or vaccine hesitancy — gone. See the other topics and US states hardest hit here:

Dette er rett og slett et folkekrav om handlekraft for Oslofjorden. Nå må regjeringen følge faglige råd og etablere store nullfiskesoner slik at økosystemet kan komme til hektene. Fiskere som rammes må kompenseres. Innsatsen mot nitrogenutslipp forsterkes. www.dagsavisen.no/debatt/2025/...

Newly published in Genetics: academic.oup.com/genetics/adv... We ask what gene flow & introgression do to gene coexpression networks. The answer is: a lot.

Reproductive barriers can evolve despite gene flow. A combination of genomics and behavioural assays shows two mitonuclear incompatibilities originated via ancient hybridization that underlie hybrid inviability in a pair of closely related swordtail fishes www.nature.com/articles/s41...

Our paper on ancient human population structure is now published. We find that the ancestors of modern humans lived in multiple populations during the period when Homo sapiens evolved in Africa. www.nature.com/articles/s41...
