Sciencealert’in haberine g\u00f6re, James Cook \u00dcniversitesinden Biyolog Linda Hernandez Duran ve \u00e7al\u0131\u015fma ekibi, \u00f6r\u00fcmceklerin zehrinin, davran\u0131\u015flara, fiziksel ko\u015fullara ve \u00e7evreye g\u00f6re de\u011fi\u015fim g\u00f6sterip g\u00f6stermedi\u011fini incelemek i\u00e7in huni a\u011f \u00f6r\u00fcmce\u011finin 4 alt t\u00fcr\u00fc \u00fczerinde deney yapt\u0131.<\/p>\n
Duran, “Ara\u015ft\u0131rmac\u0131lar, \u00f6r\u00fcmceklerin metabolizma h\u0131zlar\u0131n\u0131 tespit etmek i\u00e7in onlar\u0131n davran\u0131\u015f haritas\u0131n\u0131 \u00e7\u0131kard\u0131 ve kalp at\u0131\u015flar\u0131n\u0131 hesaplad\u0131.

D\u00fcnyada t\u00fcr\u00fcn\u00fcn en \u00f6l\u00fcmc\u00fclleri aras\u0131nda g\u00f6r\u00fclen huni a\u011f \u00f6r\u00fcmceklerinin 40’\u0131n \u00fczerinde alt t\u00fcr\u00fc bulunurken ara\u015ft\u0131rmada, “Border Ranges”, “Daring Downs”, “Southern tree-dwelling” ve “Sydney” adl\u0131 alt t\u00fcrlerin toplanma, savunma ve t\u0131rmanma davran\u0131\u015flar\u0131 incelendi.<\/p>\n
\u0130lk testte hava \u00fcflenerek veya c\u0131mb\u0131zla d\u00fcrterek \u00f6r\u00fcmceklerin y\u0131rt\u0131c\u0131l\u0131klar\u0131 incelenirken, ikinci testte hayvanlar ayn\u0131 t\u00fcrden ba\u015fka bir \u00f6r\u00fcmcek ile bir araya getirildi.<\/p>\n
