• Antragsteller: Professor Dr. Klaus-Peter Sauer

Zusammenfassung der Projektergebnisse

Unsere Untersuchungen haben klar gezeigt, dass das Paarungssystem der Panorpen keine Ressourcen-Verteidigungsstrategie ist, wie in den prominenten Lehrbüchern der Verhaltensökologie zu lesen. Die wesentlichen Merkmale dieses Paarungssystems müssen in der Stammeslinie der Panorpidae entstanden sein. Das Paarungssystem der Panorpidae ist grundsätzlich verschieden von dem der Panorpodidae.
