New paper out by our lab group! We assembled and annotated the first chromosome-level genome of Pacific herring! This herring was from the Bering Sea and represents a different genetic population than herring from the Gulf of Alaska and Pacific NW. 🐟🧬 gigabytejournal.com/articles/182

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/...

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...

Inversions support both parallel and location-specific adaptations in snail ecotypes

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...

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...

Verdens største torskebestand er påvirket av mennesker. Endringen er synlig i genene. - Titan.uio.no

Skreien er annerledes i dag enn for 100 år siden. Torsken er ikke genmanipulert. Endringene er menneskeskapte, ifølge ny forskning.

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...
