Fledermäuse sind in Agrarlandschaften auf die gemeinsame Jagd mit Artgenossen angewiesen

(PresseBox) (Berlin, )
Große Abendsegler – eine der größten heimischen Fledermausarten – suchen ihresgleichen, um bei der Jagd über insektenarmen Feldern erfolgreich zu sein. Wie Wissenschaftler des Leibniz-Instituts für Zoo- und Wildtierforschung (Leibniz-IZW) zeigen konnten, jagen die Fledermäuse über insektenreichen Wäldern vorwiegend als Einzelkämpfer, über insektenarmen Agrarflächen jedoch gemeinschaftlich in der Gruppe. Dabei orientieren sie sich offenbar an den Jagdrufen ihrer Artgenossen, die ihnen unabsichtlich Hinweise auf ertragreiche Gebiete liefern. Das „Belauschen“ der Jagdgenossen zum Aufspüren von Nahrung funktioniert vermutlich nur dann, wenn eine ausreichende Zahl von Individuen im selben Luftraum nach Insekten jagen.
