Amakhorali yenye yezinto eziphilayo ezisengozini yokufudumala kwehlabathi: njengoko ubushushu beelwandle lukhula, bona baneengxaki ezingakumbi zokuqhubeka nokukhula ngenxa yokwehla kwecalcium, izimbiwa ezibalulekileyo ekubunjweni kwazo.
Kwibhlog sithethe ngobude ngemeko ye- Indawo eNkulu yaseOstreliyaKodwa iikorale zaseHawaii azingcono kakhulu. Abaphandi kwiLebhu yeCoral Reef Ecology Laboratory, eHawaii Institute of Marine Biology babhale Isiqendu sesithathu sokuphuma kwebala elimhlophe eHanauma Bay Nature Reserve, kwisiqithi Oahu.
Xa amaqondo obushushu elwandle enyuka, abangela ulwandle ukuba lube neasidi eninzi. Amakhorali zizinto eziphilayo ezigcina ubudlelwane be-symbiotic kunye ne-algae: ngelixa ezi zityalo zibonelela nge-nitrogen, ukutya abakudingayo ukuze bakhule, ii-corals zikhusela ezi zinto zenziwe nge-photosynthetic; Nangona kunjalo, ngenxa yobushushu behlabathi ubulembu bashiya iikorale. Ngokwenza njalo, kancinci kancinci bayazenza buthathaka, benziwe mhlophe bade bafe ekugqibeleni, into eyenzekileyo kwi-9,8% yabo baseHanauma Bay Nature Reserve phakathi kowama-2014 nowama-2015.
Ngelixa iinzame zenziwe ukukhusela le ndawo ibalulekileyo, abaphandi baqaphela ukuba ukuba ubushushu behlabathi buyaqhubeka, iilwandle ziya kuqhubeka nokufunxa isixa esikhulu sekharbhon diokside kwaye ke iingqaqa zekorale kule nxalenye yomhlaba ziya kuhlala zisengozini yokunyamalala. Ukuba oku kuyenzeka, kusenokwenzeka ukuba abakhenkethi abazizigidi abatyelela le ndawo unyaka nonyaka baya kulubona utshintsho; Nangona kungenjalo kuphela, kodwa kunye neentlobo ezininzi zezilwanyana zaselwandle ezihlala apha.
