Invasive species in Hawaii threaten native birds and reptiles

Eine Studie der University of Hawaii hat festgestellt, dass streunende Katzen auf der Insel eine ernsthafte Bedrohung für die einheimische Tierwelt darstellen. Laut der Forschung fressen Katzen jedes Jahr Hunderte von Millionen Vögeln und Reptilien. Dieser Raubdruck gefährdet bereits bedrohte Arten und könnte sogar zur Auslöschung einiger endemischer Arten führen.

Die Wissenschaftler fordern daher dringende Maßnahmen, um die Population der streunenden Katzen zu kontrollieren. Sie schlagen vor, Katzen zu kastrieren und zu sterilisieren, sowie die Einführung strengerer Gesetze gegen das Aussetzen von Haustieren.

Die Studie unterstreicht die Dringlichkeit des Problems invasive Arten in Hawaii. Neben den streunenden Katzen bedrohen auch Wildschweine, Mungos und Ratten die einheimische Tierwelt. Um die bedrohten Arten zu schützen, ist es entscheidend, Maßnahmen zur Bekämpfung dieser invasiven Spezies zu ergreifen.
