Iinkumba zikhawuleza kunokuba umntu anokucinga, zigquma ngokulula iimitha ngeyure. Yiloo nto efunyenwe ngabaphandi beYunivesithi yase-Exeter xa babelandela iinkumba zegadi ezingama-450 besebenzisa ii-LED kunye nepeyinti ye-UV. Ngokufanelekileyo, iimollusks zikwathanda ukusebenzisa uhlobo lwe-slime trail slipstream. Inyaniso yokuba iinkumba zihamba ngokukhawuleza inecala layo elisezantsi: i lungworm Angiostrongylus vasorum, a I-parasite esongela ubomi kwizinja, uhamba nabo. EGreat Britain, ngenxa yeminyaka etyebileyo kwimingxuma, sele isasazeke ukusuka kwikhaya lookhokho bayo kumazantsi ukuya eScotland.
Iinkumba endleleni
Iqela elikhokelwa yi-ecologist uDave Hodgeson okokuqala wabhala ngokuchanekileyo umsebenzi wasebusuku we-snails usebenzisa izibane ze-LED ezincanyathiselwe emqolo wezilwanyana kunye nokurekhodwa kwexesha elide. Bakwasebenzisa imibala ye-UV ukwenza imikhondo yezilwanyana ezirhubuluzayo ibonakale. "Iziphumo zibonisa iinkumba ezihamba ukuya kwiimitha ezingama-25 kwiiyure ezingama-24," utshilo uHodgeson. Olu vavanyo lweeyure ezingama-72 lukwakhanyisele indlela izilwanyana eziyihlola ngayo indawo ezizingqongileyo, apho zibalekela khona, kunye nendlela ezihamba ngayo kanye.
Isazi ngendalo sithi: “Sifumanise ukuba iinkumba zihamba ngee-convoys, zihamba nge-piggyback kwi-slima yezinye iinkumba. Isizathu soku silula. Ke xa i-mollusk ilandela umzila okhoyo, ifana nokutyibilika, uHodgeson ucatshulwe yiBBC esithi. Oku kungenxa yokuba inkumba iyawonga amandla, kwaye oko kunokwenzeka kakhulu. Ngokoqikelelo, ama-30 ukuya kuma-40 ekhulwini eemfuno zamandla ezirhubuluzi abangelwa kukuveliswa kweslime.
Izifunxi-gazi ziyathuthwa
Iziphumo zifakwe kwingxelo "yeSlime Watch" yephulo laseBritane Lungworm Aware. Oku kufuna ukutsalela ingqalelo kwindlela inja ye-parasite Angiostrongylus vasorum enokuthi isasazeke ngayo ngeenkumba. Izinja ziyakwazi ukuyiginya ngokulula kunye ne-slugs encinci efunyenwe kumathoyizi okanye kwiipuddles, umzekelo. Ezi zifunxi-gazi ziye zingene emiphungeni kwaye, ngokuxhomekeke kubuzaza bohlaselo, iimpawu ziqala ukusuka. ukukhohlela, ukopha, ukugabha, kunye norhudo ukusa kumjikelo wokujikeleza kwegazi. Ukuba kukho ukukrokra ukuba inja yosulelwe yi-lungworm, ugqirha wezilwanyana kufuneka udibane ngokukhawuleza - ngoko isifo sinokunyangwa lula.
I-parasite, eyenzeka kuqala eFransi, eDenmark naseNgilani, isasazeke ngakumbi nangakumbi kwiminyaka yakutshanje, kungekhona kuphela kwi-Great Britain. UDieter Barutzki osuka kwiFreiburg Veterinary Laboratory wapapasha uphononongo ngo-2010, ngokuhambelana nolu hlobo lwelungworm ngoku luxhaphake kakhulu, ngakumbi kumzantsi-ntshona waseJamani. Kweli lizwe, iinkumba zingumsinga obalulekileyo ophakathi kwaye ngaloo ndlela zibeka umngcipheko wosulelo kumhlobo osenyongweni wendoda.
