El I-hammerhead ukrebe ubuyele endaweni emva kophando lwamva nje kunye nokubonwa okuthe kwanika ukukhanya kwindlela yokuziphatha yokufuduka koku. iintlobo zemifuziselo kunye nemeko eethe-ethe yolondolozo. Izazinzulu ziye zabeka iliso elibukhali ibhinqa eligama lingu alicia, othathe uhambo olungazange lubonwe ngaphambili kwi Pacifico, ngoxa abalobi baseYucatán baye babhala imiboniso ekhethekileyo yokutya kulo krebe ungaqhelekanga.
Umdibaniso we te knoloji Uphando lwe-Cutting-Edge kunye nentsebenziswano yamazwe ngamazwe iye yasivumela ukuba siqonde ngcono ubomi be-hammerhead shark, ngelixa sivuselela ingxoxo malunga nesidingo esiphuthumayo sokukhusela ekutshabalaleni. lokuloba kunye nezinye izoyikiso ezibeka ubomi babo esichengeni.
Ukulandela umkhondo wokuqala wehammerhead shark ukuzala
Iqela labaphandi behlabathi, elikhokelwa yi Charles Darwin Foundation kwaye ixhaswa ngamaqumrhu ahlukeneyo enzululwazi, ikwazile ukubeka iliso kumntu omdala obhinqileyo we Sphyrna lewini, enye yeentlobo zehammerhead shark ezisemngciphekweni wokuphela. Umdlali oyintloko, obizwa ngegama alicia, yayiphawulwe kwi Isiqithi saseDarwin yeziqithi zaseGalapagos ngoFebruwari 2023. I-satellite transmitter, efakwe ngononophelo ukuze ingagxininisi, yavumela ukuba idatha iqokelelwe rhoqo xa isondela phezu kolwandle.
Yintoni eyenza oku kulandelelwa kokhethekileyo kukuba, ngexesha lokuqwalaselwa, u-Alicia wenza a uhambo olumalunga neekhilomitha ezingama-6.000, ukusuka eGalapagos ukuya kunxweme lwe IPanama kwaye kamva emanzini ngamazwe. Uhambo luquka indawo yokumisa izitshixo e Igophe laseChiriquí, eyaziwa njengendawo ezizalela kuyo iihammerhead shark, apho izazinzulu zikukrokrela oko wazala amantshontsho aphakathi kwe-15 nama-30Emva kokuhlala kufutshane, u-Alicia wafudukela entshona, apho wahlala de wasweleka ibhetri yakhe yokuhambisa umkhondo ngoSeptemba, ephawula ukuphela kokulandela umkhondo.
Oku kulandelelwa kubonisa owona mgama mde urekhodiweyo ukuza kuthi ga ngoku kolu didi, kwaye ubandakanya ubungqina bokuqala benzululwazi bokuhamba kwamabhinqa akhulelweyo ukuba azale, ulwazi oluphambili lokuqonda umjikelo wobomi babo.
Uphando luqaqambisa ukubaluleka kwezi ntshukumo zokuveliswa nokugcinwa kweehammerhead sharks, abajongene nezoyikiso ezininzi kwiindawo zabo zokuhlala zendalo.
Uhlobo oluqubha ngokuchasene nelangoku: izoyikiso kunye nemingeni emitsha
El ihammerhead shark eqhelekileyo okwangoku usengozini enkulu, ngokutsho kweManyano yamaZwe ngamaZwe yoLondolozo lweNdalo (IUCN) uLuhlu oluBomvu. Abemi bayo behlabathi kuqikelelwa ukuba behle ngaphezu kwama-80% kwizizukulwana ezithathu nje, ikakhulu ngenxa ukuloba kakhulu, ukuthotywa kweendawo eziselunxwemeni kunye nemfuno emandla yamaphiko azo kwiimarike zamazwe ngamazwe.
Iingcali zigxininisa ukuba, nangona kukho iindawo ezithile ezikhuselweyo zaselwandle, iimazi ezininzi ezikwinkqubo yokuzala zisabanjwa xa zifuduka ixesha elide. Ngaphezu koko, ookrebe abasandul’ ukuzalwa Bakwafumana imiphumo yoxinzelelo lokuloba kwiindawo ezifuywayo eziselunxwemeni, nto leyo ethintela ukubuyiswa kolu didi.
Enye inyani efanelekileyo enikezelwe luphando kukuba u-Alicia uchithe malunga ne-40% yexesha lokulandelela amanzi ngamazwe, ngaphandle kwemida ekhuselweyo yeGalapagos. Le nyaniso ibonisa ukuba intsebenziswano yengingqi nehlabathi Kubalulekile ukuyeka ukuloba ngokungakhethiyo kulwandle oluphezulu nokuqinisekisa ukuphila kwezi zilwanyana.
I-Adventures yoNxweme: Ukubukela iintaka kunye nokuzingela eYucatan
Ngaphandle kweeprojekthi zesayensi, i-hammerhead shark isanda kuba yi-protagonist ye- into yentsholongwane kwimidiya yoluntu enkosi kwividiyo erekhodiweyo kufuphi neRío Lagartos, kwimpuma yeYucatán. Kushicilelo, abalobi bendawo babamba umzuzu xa umfuziselo wolu didi utya imitha, indlela yokuziphatha yendalo eqaqambisa ubuchule bokuzingela yokrebe kunye nokubaluleka kwayo kwendalo.
Ubungakanani obumangalisayo bukakrebe kunye nobuchule bokuzingela buye batsala umdla kuluntu olukwi-intanethi, nto leyo evelisa umdla ohlaziyiweyo kwisimo sohlobo kunye ne-ikholoji. Ngokutsho koMphathiswa wezeNdalo kunye neMithombo yeNdalo (iSemarnat), I-hammerhead ukrebe Inokufikelela kwiimitha ezine ubude kwaye ihlala kulwandle olushushu nolupholileyo kwihlabathi jikelele, nangona uxinzelelo lomntu luyigcina njengenye yezona ntlobo zokrebe ezisesichengeni.
Ezi ntlobo zobungqina, zombini ezivela kwizazinzulu kunye nabemi, zigxininisa ulwazi olulinganiselweyo esinalo malunga nokuziphatha kunye nokufuduka kwee-hammerhead sharks, kodwa kunye nesidingo sokuphucula ukhuseleko lweendawo zabo zokuhlala kunye nokulawula ukubanjwa kwabo ngengozi.
Inkqubela phambili ekulandeleni umkhondo kunye nokwanda kolwazi lwentlalo ityhila iinkcukacha ezazingaziwa ngaphambili malunga naba krebe banemifanekiso kunye nohambo lwabo olubanzi. Amabali afana neka-Alicia kunye nezinto ezibonwe eYucatán zibalaselisa ukubaluleka kwe-a isenzo esilungelelanisiweyo kwaye uzinzile ukuqinisekisa ukuba ihammerhead shark iyaqhubeka nokuzulazula elwandle kwaye igcine indima yayo ephambili kulungelelwaniso lwaselwandle.
