Der Clou der Grashüpfer

Oldenburger Hörforscher Jannis Hildebrandt untersucht Hörsystem von Heuschrecken

(PresseBox) (Oldenburg, )
Nachts, wenn es ruhig ist, wirkt das Martinshorn eines Krankenwagens wie eine akustische Erschütterung. Am Tag, an einer verkehrsumtosten Straße, ist dasselbe Martinshorn lediglich eine Geräuschquelle unter vielen - sehr laut immer noch, aber ohne die nächtlich erbarmungslose Durchschlagskraft. "Adaptation" nennen Forscher den Mechanismus, mit dem sich das Sinnessystem sowohl von Menschen als auch von Tieren an seine Umgebung anpasst. Der Oldenburger Hörforscher Prof. Dr. Jannis Hildebrandt hat sich dem Phänomen gewidmet - und dabei Neues über das Hörsystem von Grashüpfern herausgefunden. In einer Studie in der renommierten biologischen Fachzeitschrift PLOS Biology zeigt Hildebrandt: Das Gehör von Grashüpfern justiert sich zrtzg qtymwb mwa, my jjz Fqumsse tgy Buzkewrfutl on zsdriayfjqcvi Xkkspehtgg whm poedu um gqnmvj.
