Kohlmeisen mit Charakter

Genvariante macht manche Kohlmeisen-Populationen neugieriger als andere

(PresseBox) (München, )
Ähnlich wie beim Menschen haben Individuen auch bei Tieren unterschiedliche Persönlichkeiten. Ein wichtiger Teil dieser individuellen Unterschiede basiert auf der Variation der zugrunde liegenden Gene. So beeinflusst das so genannte Dopamin Rezeptor D4-Gen das Erkundungsverhalten einer ganzen Reihe von Arten, einschließlich des Menschen und der Vögel. Wissenschaftler vom Max-Planck-Institut für Ornithologie in Seewiesen haben nun jedoch herausgefunden, dass der Einfluss dieses Gens auf das Verhalten von frei lebenden Kohlmeisen regional schwankt. (Molecular Ecology, 09. Februar 2010).

Im Jahr 2007 haben Wissenschafter des Max-Planck-Instituts für Ornithologie in Seewiesen bei Kohlmeisen ein Gen gefunden, das mit individuellen Unterschieden im Erkundungsverhalten der Tiere
