A recent study addresses the long-standing energy balance closure problem within ecosystem flux measurements 🌳 By using datasets from ICOS and NEON, the study shows that a substantial part of this energy imbalance is caused by incomplete energy accounting. Read more: www.icos-cp.eu/news-and-eve...

Finanziell ist akademische "Karriere" 1 katastrophale Entscheidung. In meinem Fall: erst Teilzeit, dann Erwerbsarbeitslosigkeit. Mehrere Umzüge. Horrende Pendelkosten. 2 Wohnungen seit 2017. Aber klar, Lars, lass mal uns Akademiker_innen noch länger arbeiten lassen bis zur Winz-Rente! So attraktiv.

Thank you to the Peat4People project for inviting us from WG Peatland Science to support upcoming GHG measurements in African peatlands. Thanks to externally funded PhD thesis work by Hauke Schmülling and collaboration with @zalf.bsky.social we provide low-cost chambers and knowledge..

Heute gedenken wir der Opfer des Nationalsozialismus und der Befreiung von Auschwitz-Birkenau am 27.01.1945. Erinnern heißt kämpfen! Gerade heute, wo rechte Kräfte erstarken und Gedenkarbeit unter Druck steht. Nie wieder ist jetzt und darf nicht zur leeren Worthülse werden!

So the bad news is that impacts of_extreme_droughts worsened dramatically over time, but the good news is that these systems were not progressively impaired by_moderate_droughts. And, for us, it's good news that we have published these findings! Stay tuned; many more DN manuscripts are in progress.

Yellow-flowering goldenrod plants poke through the tops of rainout shelters for the International Drought Experiment (IDE) in a field at the Purdue Wildlife Area near West Lafayette, Indiana, USA. This was one of 74 IDE sites used in the study.

...while the effects of droughts that were extreme (i.e., 1 in 100 year events) compounded over time, perennial grasslands and shrublands were more resilient to less extreme droughts. That is, drought-related reductions in plant growth did not magnify over more years of moderate drought. (2/3)

Two panel graph showing the productivity response of ecosystems to moderate drought remained constant from 1-4 years of drought, while the productivity progressively decreased from the first to the fourth year of drought in systems consistently exposed to extreme drought.
