| Description |
English: Small pool (= puddle) in a gravel pit – habitat of tadpoles from the Natterjack Toad, Epidalea (Bufo) calamita.
Deutsch: Episodischer Tümpel (Regenwasserpfütze) in einer Kiesgrube – Lebensraum von Kaulquappen der Kreuzkröte, Epidalea (Bufo) calamita. Die Gefahr des vorzeitigen Austrocknens nimmt diese Lurchart "bewusst" in Kauf; dafür findet die Entwicklung in dem nur wenige Zentimeter flachen, warmen Gewässer besonders schnell statt und es gibt keine aquatilen Fressfeinde oder Nahrungskonkurrenten. Das Nahrungsangebot ist allerdings auch knapp – hauptsächlich organische Schweb- und Sinkteilchen (Detritus) und Algen, gelegentlich ein toter Artgenosse. Das Vorhandensein sehr unterschiedlich großer Kaulquappen deutet hier auf mindestens zwei zeitlich versetzte Laichvorgänge hin. |
