Wie die Biene zur Blume kommt

(PresseBox) (Wien, )
Bienen können lesen - nein, keine Romane, sondern Blütenmuster: Im Experiment mit Honigbienen fanden der Evolutionsbiologe Johannes Spaethe und sein Team an der Universität Wien heraus, dass die Insekten komplexe Formen unterscheiden und wiedererkennen können. Warum sie das im "Bienenalltag" überhaupt brauchen, und was für eine Rolle optische Signale in der Pflanze-Bestäuber-Interaktion sonst noch spielen, untersuchen die ForscherInnen in einem aktuellen FWF-Projekt.

Für welche Blüte entscheidet sich eine Biene im Pflanzenmeer der Blumenwiese? "Um das zu verstehen, muss man die Welt durch die Augen der Biene betrachten", sagt Johannes Spaethe vom Department für Evolutionsbiologie.
