Europäer schleppten Katzen nach Australien ein

Wissenschaftler des Senckenberg Biodiversität und Klima Forschungszentrums haben gemeinsam mit einem internationalen Team die Einschleppung von Katzen nach Australien untersucht. Sie kommen anhand von DNA-Untersuchungen zu dem Schluss, dass die Katzen von europäischen Siedlern im 18. Jahrhundert eingeführt wurden. Heute zählen die wildlebenden Katzen zu einer der größten Bedrohungen der australischen Artenvielfalt. Die Studie wurde kürzlich im Fachjournal „BMC Evolutionary Biology“ veröffentlicht.

Columns of workers penetrate the forest, furiously gathering as much food and supplies as they can. They are a massive army that living things know to avoid, and that few natural obstacles can waylay.

Kieferzähne und Schuppen von Wirbeltieren haben unterschiedlichen Ursprung

Aktuelle Forschungsergebnisse der PaläontologInnen Jürgen Kriwet und Cathrin Pfaff von der Universität Wien bringen eine klassische Evolutionstheorie der Wirbeltiere ins Wanken: Die Kieferzähne von Haien und Rochen sollen demnach nicht direkt von den äußeren Körperschuppen abstammen. Die Studie wird aktuell im Fachjournal “Proceedings of the Royal Society B” veröffentlicht.
