Ngokusho kocwaningo olusha olwenziwe ososayensi abavela e-University of Bristol futhi bashicilelwe ngo-Journal of Ecology, iziza zasekhaya namuhla zingumthombo omkhulu wokudla kwama-pollinator wezinambuzane, kufaka phakathi izinyosi namadolobha.
Ukutadisha okokuqala kwalinganiswa, mangaki umpe okhiqizwa ezindaweni zasemadolobheni, lapho izingadi zokuhlala zakha iningi labantu - ngokwesilinganiso, cishe amaphesenti angama-85 endawo ahlala kuyo.
Imiphumela ikhombisile ukuthi ngezingadi ezintathu nsuku zonke zakha isipuni setiyi se-Ambrosia yemvelo, ushukela oluyingqayizivele olunoshukela olunoshukela oluqukethwe izimbali eziphuza i-pollinators ukuthola amandla.
Yize isipuni singabonakala sincane kithi, sihunyushwe kusuka enhlokweni ngesilinganiso somuntu kuzoba yithoni ye-ambrosia. Ngakho-ke, isipuni esisodwa kwanele 'ukugcwalisa amandla ezinkulungwane zezinyosi ezindizayo.
Isazi seze-Ecologist Nicholas Tyu, umlobi oholayo, uthe: "Yize isibalo kanye nokwehlukahlukana kompetha kwakuvame ukukalwa ezindaweni zasemakhaya, akuzange kwenziwe ngezindawo zasemadolobheni zokuhlaziywa okunjalo. Silindele ukuthi izingadi ezizimele zibe ngumthombo ocebile we-NEctar, kodwa zimangele ngesilinganiso sokukhiqizwa. Imiphumela yethu igcizelela indima ebalulekile edlalwa izakhamizi zasehlobo ekuxhaseni ama-pollinators kanye nokunyuswa kwezinyoni. "
Kulolu cwaningo, olwenziwe ngokubambisana namanyuvesi ase-Edinburgh kanye nomphakathi wasebukhosini, ukukhiqizwa komkhakha emadolobheni amakhulu amane e-Great Brithain: Bristol, Edinburgh, Leeds and Finnish. Cishe ingxenye yesithathu (amaphesenti angama-29) ezindaweni zasemadolobheni ezazihlala iziza zasekhaya, okungamapaki ayisikwele esihlatshelelwa amahlandla ayisithupha.
Ukukhiqizwa kwe-Nectar kukalwa ngezilwane ezicishe zibe ngu-200 ngokukhipha umpe kusuka emibala engaphezu kwama-3,000. Ukuhlushwa ushukela ecret kunqunywa kusetshenziswa i-refruckometer, idivaysi ekala ngokukhanya lapho kuvinjelwa khona lapho kudlula ikhambi.
"Sithole ukuthi ukubekeka umpendela emadolobheni ahlukahlukene kakhulu, ngamanye amagama, kuvela ezinhlotsheni zezitshalo eziningi kunakubantu abazimele," umhlanganyeli uNicholas TYU waphawula.
"Ucwaningo lubonisa indima enkulu abalimi abadlalayo lapho belondolozele ama-pollinators, ngoba ngaphandle kwezingadi bekuzoba ukudla okuncane kakhulu kwabaphangi, kufaka phakathi izinyosi, ama-OS, izimvemvane, amabhu, izimpukane namabhungane. Kubalulekile ukugcina izingadi zangasese, futhi abanikazi bazo bahlinzeka ngezincomo ukwenza izindawo zibe lula kuma-pollinator. Lokhu kufaka phakathi ukugcwala okucebile ngombala wemibala, utshani obuvame ukusika futhi uvikele ukufafaza izibulala-zinambuzane ezingalimaza ama-pollinks. Kufanele futhi igweme ukuhlanganiswa kwengadi egandayiwe, phansi noma owokuqala, "kuchaziwe.
