Nooca ugu yar xayawaanka Xamaaratada ee adduunka oo la helay
Seynisyahannada ayaa aaminsan inay heleen nooca ugu yar ee xayawaannada la isku yiraahdo "Xamaaaratada" ee dunida oo dhan, kaas oo ah jirjiroole aad u yar oo la eg miraha abuurka beeraha.
The Brookesia has a body just 13.5mm long Labo kamid ah jirjiroolayaasha ayaa waxaa helay koox baarayaal oo ah ka kooban khubaro u dhalatay Jarmalka iyo Madagascar, oo ku sugan dalka Madagascar. Jirjiroolahan labka ah oo lagu magacaabay Brookesia nana, ama eray bixinta seyniska lagu yiraahdo "nano-chameleon", ayaa cabirka jirkiisu yahay 13.5 mm, kaas oo ka dhigaya xayawaanka ugu yar ee xamaratada la yaqaano oo gaaraya ilaa 11,500, sida uu sheegay ururka cilmibaarista xayawaanka oo fadhigiisu yahay Magaalada Munich. Kan dhedigga ah ayaa cabirkiisu yahay 29mm, sida uu ururku sheegay. "Jirjiroolaha cusub ayaa laga helay keyn ku taalla Waqooyiga dalka Madagascar, waxaana jirta cabsi laga qabo inuu baaba'o" ayaa lagu yiri warbixinno ay soo saareen seynisyahanada. Cilmi baarayaasha ayaa ogaday in jirjiroolaha uu maalintii ugaarsado cayayaanka injirta halka habeenkiina uu ku dhuunto cawska isagoo iska qarinayo xayawaanka kale ee isaga ugaarsada. Qoraal uu soo dhigay boggiisa gaarka ah ayuu Dr Mark Scherz, oo kamid ah cilmi baarayaashii ku lug lahaa soo bandigidda arrintaas ugu yeeray "tallaabo cajiib ah" Wuxuu intaa ku daray in keymaha laga helay Jirjiroolayaasha lagu magacaabay Brookesia weli lala xiriirinayo kuwa kale, oo laga yaabo inay ku nool yihiin guud ahaan Waqooyiga jasiiradda. "Marka, jirjiroolahan cusub ee aadka u yar ayaa soo afjaray helitaankii isdaba joogga ahaa ee cayayaanada laga helay jasiirado yar yar. Taasi waxay ka dhigantahay in uu jiro wax kale oo u ogolaanaya ama keenaya cirib tirka jirjiroolayaasha," ayuu intaasi raaciyay. Seynisyahannada waxay warbixintooda ku soo jeediyeen talo ku aaddan in jirjiroolahan cusub lagu soo daro liiska xayawaannada khatarta ugu jira in ay dabar go'aan ee ururka caalamiga ee ilaalinta khayraadka dabiiciga ee loo soo gaabiyo IUCN si loo ilaaliyo.
