Last week I was at the www.tropicalbiosummit.org Indeed, very interesting - many great speakers and much inspiration!
One morning I was able to go birding before the conference - also a nice experience to see some wetland birds.

Wir erinnern an Amadeu Antonio. 🕯️
Heute vor 35 Jahren wurde Amadeu von einem Neonazi-Mob in Eberswalde brutal attackiert. Amadeu verstarb am 06.12.1990 an den Folgen des rassistischen Angriffs.

Jetzt übernehmen die Fridays selbst schon die Kritik der Ignoranten. Nicht die Klimabewegung hat enttäuscht. Sie hat mich und viele andere begeistert. Enttäuscht haben Medien und Mehrheitsgesellschaft, die das für sie teuer errichtete Denk-Mal ohne nachzudenken weggerissen haben weil störend.
Fridays for Future hat ihr Potenzial nicht ausgeschöpft. Es ist zentral, die Klimakrise nicht nur als physikalisches Ereignis zu begreifen.

My observation of the day: Carabus granulatus heavily colonised by the mite Iphidosoma fimetarium. Naturally, I had no idea which mite this might be - iNaturalist owen_seeman provided the identification. 👍 iNaturalist #stadtnatur, #berlinbiodiversity, #berlin, #urbanbiodiversity

Using fish teeth fossils from lake sediments, we found the haplochromine cichlids diversified quite rapidly and the entire food web evolved within just the first three millennia after the formation of modern Lake Victoria (which started refilling ~ 17k years ago). www.nature.com/articles/s41...
Fossil evidence for trait diversification in an adaptive radiation - Scientific Reports
Adaptive radiation is an important process for the origin of functional and ecological biodiversity. Understanding how, when, and why adaptive radiations occur is a long-standing interest in evolution...

Our son now studies in Freiburg/Breisgau. Good reason for a visit to the city and the Belchen, one of the most important places within the hotspot area for lichens in Germany. Breathtaking indeed, even we found only 60 of the about 1000 species. Some highlights.

Nice Tree of Souls (Hericium coralloides) seen today close to Berlin. Despite intensive search, no Omatikaya Na’vi were seen, but Eywa stopped us to take it home. A strictly protected species here.
