Der Start ins Leben: ein Sprint und ein Ritt auf der Strömung
Wissenschaftler verfolgen Meeresschildkröten-Babys mit winzigen Sendern 23.10.2014/Kiel. Mit Hilfe von winzig kleinen akustischen Sendern verfolgten Wissenschaftler des GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel, der Turtle Foundation und der Queen Mary University of London auf den Kapverdischen Inseln erstmals die Wege frisch geschlüpfter Unechter Karettschildkröten. Die Tiere durchqueren zügig die Küstengewässer, in denen sie leicht zur Beute […]
