Wenn es lieber auf Deutsch sein soll, hier ist ein Interview von RBB info zum heute in Kraft tretenden marinen Biodiversitätsabkommen www.ardaudiothek.de/episode/urn:...
Podcast: UN-Hochseeschutzabkommen: Was es tatsächlich bringt
Das UN-Hochseeschutzabkommen wurde von 145 Staaten unterzeichnet, am Samstag tritt es in Kraft. Es sei ein Meilenstein - allerdings am Anfang eines sehr langen Weges, sagt Biologe Helmut Hillebrand.

@ckunze.bsky.social tested whether the concept of response diversity holds for pulse disturbances & realized response diversity. Turns out interaction strength is key. Great collaboration w @owpet.bsky.social & Shyamolina Gosh @icbm-uol.bsky.social @hifmb.de

The topics range from the difficulty of measuring biodiversity to the different emotions about or with biodiversity. Thanks to the brilliant input from early career scientists, it became both an introduction to the topic of biodiversity change and a plea for interdisciplinary collaboration.
More than a year ago researchers from @hifmb.de and @icbm-uol.bsky.social started to write about different perspectives on marine biodiversity change from natural and social science perspectives. This morphed into a review paper that was published online today link.springer.com/article/10.1... 🧪

Der Bundeskanzler brüskiert das Gastgeberland der #COP30, dabei zeigt Belém, wie ernst es #Klimaschutz nimmt. Die Gastgeber*innen haben alles getan, um Fortschritte beim Ausstieg aus fossilen Energien und bei einer gerechten Wende zu ermöglichen. Dafür gebührt Belém und Brasilien unser Dank.

Impressions from the fantastic Rockit festival in Groningen yesterday. Many wow moments with Mary Halvorson, Immanuel Wilkins, Makaya McCraven and Dave Holland. Among these highlights, the new Dave Holland trio stood out as a masterly and emotional performance of jazz Grandezza #jazzsky

First time I saw Jack deJohnette live, almost 40 years ago, was in Vienna, an outerworldly concert with Jarrett and Peacock, but most impressive was this melodious drummer hovering over his drum set to effortlessly paint rhythms. A genius will be missed.
