Izinhlobo (Izinyoni):Ama-Chinese Egrets (Egretta eulophotata)
Ijenali:Ucwaningo Lwezinyoni
Abstract:
Ulwazi lwezidingo zezinyoni ezifudukayo lubalulekile ekuthuthukiseni izinhlelo zokulondoloza izilwane ezisengozini yokufuduka. Lolu cwaningo beluhlose ukunquma imizila yokufuduka, izindawo zasebusika, ukusetshenziswa kwendawo, kanye nokufa kwama-Chinese Egrets amadala (Egretta eulophotata). Ama-Chinese Egrets amadala angamashumi ayisithupha (abesifazane abangu-31 nabesilisa abangu-29) esiqhingini sokuzalanisa esingasogwini esingahlali muntu e-Dalian, e-China alandelelwa ngomkhondo kusetshenziswa ama-GPS satellite transmitters. Izindawo ze-GPS ezirekhodwe ngezikhathi zamahora angu-2 kusukela ngoJuni 2019 kuya ku-Agasti 2020 zisetshenziselwe ukuhlaziywa. Isamba sabantu abadala abangu-44 kanye nabangu-17 abalandelwayo baqede ukufuduka kwabo kwasekwindla nasentwasahlobo, ngokulandelana. Uma kuqhathaniswa nokufuduka kwasekwindla, abantu abadala abalandelwayo babonise imizila ehlukahlukene kakhulu, inani eliphakeme lezindawo zokuma, isivinini sokuhamba esihamba kancane, kanye nobude besikhathi sokufuduka entwasahlobo. Imiphumela ibonise ukuthi izinyoni ezifudukayo zazinamasu ahlukene okuziphatha phakathi nezinkathi ezimbili zokufuduka. Ubude besikhathi sokufuduka kwentwasahlobo kanye nesikhathi sokuma kwabesifazane besiside kakhulu kunesabesilisa. Ukuhlobana okuhle bekukhona phakathi kokufika kwentwasahlobo nezinsuku zokusuka entwasahlobo, kanye naphakathi kwedethi yokufika yasentwasahlobo kanye nobude besikhathi sokuma. Lokhu okutholakele kubonise ukuthi ama-egrets afika ngaphambi kwesikhathi lapho azalela khona asheshe ashiya izindawo zasebusika futhi abe nesikhathi esifushane sokuma. Izinyoni esezikhulile zazincamela izindawo ezingamaxhaphozi ezinamanzi, izindawo ezinamahlathi, namachibi ezilwane zasemanzini lapho zifuduka. Ngesikhathi sasebusika, abantu abadala babethanda iziqhingi ezingasogwini lolwandle, amaxhaphozi aphakathi kwamagagasi, namachibi okulima emanzini. Ama-Chinese Egrets Abadala abonise izinga lokusinda eliphansi uma kuqhathaniswa nezinye izinhlobo ezivamile ze-ardeid. Izibonelo ezifile zatholakala emachibini e-aquaculture, okubonisa ukuphazamiseka komuntu njengembangela enkulu yokufa kwalolu hlobo olusengozini. Le miphumela igqamise ukubaluleka kokuxazulula izingxabano phakathi kwama-egrets namaxhaphozi enziwa abantu kanye nokuvikela amaflethi aphakathi kwamagagasi neziqhingi ezingasogwini ezindaweni ezingamaxhaphozi emvelo ngokusebenzisana kwamazwe ngamazwe. Imiphumela yethu ibe nomthelela kumaphethini waminyaka yonke wokufuduka kwe-spatiotemporal waminyaka yonke wama-Chinese Egrets amadala, ngaleyo ndlela inikeze isisekelo esibalulekile sokulondolozwa kwalolu hlobo olusengozini.
