Sidste \u00e5r blev skoleb\u00f8rn opfordret til at grave i jorden p\u00e5 jagt efter sm\u00e5kryb som biller, b\u00e6nkebidere og orme i forbindelse med eksperimentet \u00bbCatch that bug!\u00ab. Samtidig deltog astronauter, der var med p\u00e5 ESA\u2019s CAVES-tr\u00e6ningsforl\u00f8b under jorden, i det verdensomsp\u00e6ndende eksperiment dybt under den italienske \u00f8 Sardinien.<\/p>\n<\/div>\n

Under CAVES 2013 samarbejdede ESA-astronauten Paolo Nespoli med biologen Paolo Marcia om at unders\u00f8ge en del af Sos Jocos-hulen. P\u00e5 trods af det permanente m\u00f8rke fandt de 25 arter p\u00e5 et omr\u00e5de p\u00e5 blot 20 cm i kvadrat. I alt blev der fundet 124 krybdyr, hvilket tyder p\u00e5 en bestandsdensitet p\u00e5 over 3 milliarder dyr pr. kvadratkilometer.<\/p>\n

En af de 25 identificerede arter var et sj\u00e6ldent, b\u00e6nkebiderlignende dyr, som aldrig f\u00f8r var blevet observeret i denne hule. Arten, der f\u00f8rst blev opdaget i 2009, er den eneste art i sin familie, der kan leve b\u00e5de i huler og over jorden.<\/p>\n

En anden sj\u00e6lden art, som astronauterne fandt under CAVES2013, var en bille, der kun findes i grotter p\u00e5 Sardinien. Nu, hvor biologerne har tre eksemplarer af billen, kan de foretage en DNA-analyse for at finde ud af, hvor den passer ind i stamtr\u00e6et.<\/p>\n

Der blev desuden fundet et 4 mm langt, b\u00e6nkebiderlignende dyr, der tilh\u00f8rer en ny art, som Paolo Marcia opdagede for tre \u00e5r siden. Takket v\u00e6re astronauternes indsats vil dette dyr snart f\u00e5 tildelt et videnskabeligt navn.<\/p>\n

Se Paolo og Paolo gennemf\u00f8re eksperimentet, og download detaljerne til brug i din klasse. Hvem ved, hvad du m\u00e5ske finder lige under dine f\u00f8dder.<\/p><\/p>","protected":false},"excerpt":{"rendered":"
