Ubomi baselwandle kwiipali nakwiitropiki busongelwa kukufudumala komhlaba kunye nokuloba okugqithisileyo

Iminatha yokuloba nolwandle

Ngakumbi nangakumbi kuthi sihlala kulo mhlaba sele wonakale. Izixhobo ebesinazo ngaphambili ziyaphela kancinci. Umhlaba awunako ukuzinika ngakumbi ngokwawo. Kwaye le yinto esiyibona yonke imihla: iqondo lobushushu lehlabathi liyenyuka, iipali ziyanyibilika zibangela ukunyuka kwenqanaba lolwandle, iimeko zemozulu ziya zisiba mandundu,… phakathi kweminye imisitho emininzi esikuxelela yona kwibhlog.

Kwiitropiki nasezibondeni baneengxaki ezimbini ezinzima: enye kukufudumala komhlaba, kwaye enye kukuloba kakhulu.. Ubomi baselwandle kuyo yomibini le mimandla busengozini.

Uphononongo olwenziwe ngabaphandi abavela eSpain, e-Australia naseNew Zealand, oluye lwapapashwa kwiphephancwadi i-Science Advances, luyakungqina oku. Unyaka ka-2016 ngowona ushushu kwimbali erekhodiweyo, kwaye obobushushu babufunxwe ubukhulu becala lulwandle. Ngenxa yemeko, izilwanyana zaselwandle zinzima ukufikelela phambili.

Ngethuba lokuqala, uphando luthathela ingqalelo, ngokusebenzisa imifanekiso yesathelayithi, ukwanda kweqondo lobushushu elwandle, utshintsho kumaza olwandle kunye namanqanaba emveliso yaselwandle kule minyaka ingamashumi amathathu idlulileyo.

Iintlanzi zokudada elwandle

Ngaloo ndlela, Abaphandi banokufumanisa ukuba zeziphi iindawo ezinezinto eziphilayo zolwandle eziphakathi kwezona zichaphazeleka kakhulu kukufudumala komhlaba, ezizezona zikufutshane neetropiki kunye neepali, ezinje ngonxweme olusempuma ye-United States naseCanada, indawo yeikhweyitha, uLwandle loMntla okanye umzantsi-mpuma we-Australia ne-New Zealand.

Ngokuthelekisa idatha yesifundo kunye nolwazi malunga nomsebenzi wokuloba kule minyaka ingama-60 idlulileyo Baye baqonda ukuba ezona ndawo zinentlobo ngeentlobo zezinto eziphilayo zaselwandle zezona zichaphazeleka kakhulu kukuloba kakhulu. Ngesi sizathu, iimpembelelo zokuloba kwimizi-mveliso kunye nemozulu kufuneka ziqwalaselwe "ngaxeshanye kulondolozo" lwezi ndawo, ngokukaFrancisco Ramírez, umphandi kwisikhululo seDoñana Biological Station (EBD-CSIC), owongeze wathi "Asikokuphela kokuloba koko kuphunyezwa imigaqo-nkqubo yolondolozo».
