Want to conserve #birds, #mammals and other vertebrates? Then don’t forget their #insects. Our new Nature Reviews Biodiversity paper explores the many ways vertebrates depend on insects — for food, shelter, protection and much more. I’ve written about it here: jeffollerton.co.uk/2026/09/30/w...

It’s sometimes easy to forget quite how much of the living world depends upon insects. That might seem an odd thing for someone who has spent much of his career studying insects and their relations…

Asterix Archiv 🐗 @comedix.de · 20/09/2026
Eine schöne Bastel- und Malarbeit. Manchmal trägt Obelix den Hinkelstein. Manchmal ist Obelix der Hinkelstein. Dürfte nicht leicht gewesen sein, diesen Stein zu finden. #Asterix #Fanart
Das Bild zeigt einen kleinen, länglichen und nach oben abgerundeten Stein, dessen Form an einen Hinkelstein erinnert. Der Stein wurde rundherum so bemalt, dass er selbst zum Körper von Obelix wird.
Auf der Vorderseite sind Obelix’ Gesicht mit den roten Zöpfen, sein nackter Oberkörper sowie der grüne Gürtel mit großer gelber Schnalle zu sehen. Darunter setzt sich seine typische blau-weiß gestreifte Hose bis zum unteren Rand des Steins fort. Seine Füße stehen auf einer kleinen grünen Wiese, die mit roten Pilzen und Blumen verziert ist. Der obere, dunkelgraue Teil des Steins bleibt weitgehend unbemalt und wirkt dadurch wie ein Hinkelstein, der hinter Obelix aufragt.
Die Rückseite löst den kleinen optischen Scherz auf: Dort fehlen Kopf und Oberkörper völlig. Stattdessen sieht man nur Obelix’ Arme, die sich von beiden Seiten um den grauen Stein legen. Seine Hände greifen hinter dem „Hinkelstein“ ineinander. Darunter sind wiederum die gestreifte Hose und seine Füße auf der Wiese zu erkennen.
