Rahyada qaar ayaa dhalaala marka makhribka, iyagoo isticmaalaya isku-xidhka fluorescent, saynisyahannadu waxay yiraahdeen
Sannadkii 2017, saynisyahannadu waxay ku dhawaaqeen mucjiso dabiici ah, qaar ka mid ah rahyadu waxay dhalaalayaan fiidkii, iyagoo isticmaalaya isku-dhafka fluorescent oo aynaan horay u arkin dabeecadda.
Waqtigaas, lama ogeyn inta nooc ee rahyada ah ee soo saari kara iftiinkan.
Daraasad lagu sameeyay 151 nooc oo rahyada Koonfurta Ameerika ah ayaa muujinaya heerka fluorescence ee nooc kasta oo gaar ah. Xogta laga helay daraasadda ayaa sheegaysa in fluorescence ay ku xidhan tahay aragga raha.
Sida ay saynis-yahannadu sheegeen, qiiqa soo baxaa waxa uu saameeyaa habka rahyadu isu sheegaan. Waxay aaminsan yihiin in fluorescence ay ka celiso ugaarsiga.
"Daraasad goobeed lagu sameeyay Koonfurta Ameerika, waxaan ogaanay oo aan diiwaangalnay qaababka biofluorescence ee amphibians kulaylaha," ayuu qoray bayoolajiga Jaamacadda Gobolka Florida Courtney Witcher.
"Waxyaabo badan oo ku jira boqortooyada xayawaanka ayaa dhalaalaya, laakiin sababtu mar walba ma muuqato," saynisyahannadu waxay tilmaamayaan.
Fluorescence waa nuuc dhalaal ah oo abuurma marka iftiinka la nuugo oo dib loo soo saaro mawjadaha dhererka kala duwan, waxaana lagu arkaa noocyo badan, oo ay ku jiraan shark, chameleons iyo salamanders. Lafaha sidoo kale fluoresce, saynisyahano sharaxay.
Biofluorescence-ka laga soo saaro maqaarka rahyadu way ka duwan yihiin fluorescence ee xayawaanka kale ee iftiinka leh.
Iftiinka buluuga ah, kaas oo ugu dhow madawga dabiiciga ah ee dhulka, ayaa soo saara iftiinka ugu xoogga badan, iftiinka laftiisa ayaa ugu horreyntii u muuqda laba heer oo kala duwan oo iftiin muuqda ah - cagaar iyo orange, saynisyahannadu waxay yiraahdeen.
Rah badan ayaa mad-madow ah - taas oo ah, waxay firfircoon yihiin fiidkii. Noocyada qaarkood, indhahooda waxaa loogu talagalay inay si fiican ugu shaqeeyaan iftiinkan, oo ay ku badan yihiin sawir-qaadayaasha usha usha leh oo xasaasi u ah cagaarka iyo buluugga, ayuu qorayaa Science Alert.
Dhallaanka cagaarka ah ee raha ayaa aad u ifaya maalintii, saynisyahannadu waxay sharraxeen. Qaybaha jidhka ee dhalaalaya waa kuwa ugu badan ee ku lug leh isgaadhsiinta xayawaanka, kuwaas oo ah dhuunta iyo dhabarka. Tani waxay soo jeedinaysaa in biofluorescence ay qayb ka tahay qalabka isgaarsiinta ee rahyada.
