Izinhlobo (zezinyoni):Ama-whimbrels (Numenius phaeopus variegatus)
Isifinyezo:
Ukulondoloza izinyoni ezifudukayo kuyinselele ngenxa yokuthembela kwazo ezindaweni eziningi ezikude ezigabeni ezahlukene zomjikelezo wazo wokuphila waminyaka yonke. Umqondo "womgwaqo ondizayo", obhekisela kuzo zonke izindawo ezimbozwe ukuzala, ukungazali, nokufuduka kwezinyoni, unikeza uhlaka lokubambisana kwamazwe ngamazwe ukuze kulondolozwe. Nokho, endleleni efanayo yokundiza, imisebenzi yokufuduka yohlobo olufanayo ingahluka kakhulu phakathi kwezinkathi nenani labantu. Ukucacisa umehluko wezinkathi nenani labantu ekufudukeni kuyasiza ekuqondeni i-ecology yokufuduka kanye nokuhlonza izikhala zokulondolozwa. Izindlela Sisebenzisa ukulandelela ngesathelayithi silandelele ukufuduka kwe-Whimbrels (Numenius phaeopus variegatus) ezindaweni ezingazali eMoreton Bay (MB) naseRoebuck Bay (RB) e-Australia e-East Asian-Australasian Flyway. Ukuhlolwa kwe-Mantel kwasetshenziswa ukuhlaziya amandla okuxhumana kokufuduka phakathi kwezindawo ezingazali kanye nezindawo zokuzalela zabantu be-MB kanye ne-RB. Ukuhlolwa kuka-Welch's t kwasetshenziswa ukuqhathanisa imisebenzi yokufuduka phakathi kwalezi zinhlobo ezimbili kanye naphakathi kokufuduka okuya enyakatho naseningizimu. Imiphumela Ngesikhathi sokufuduka ngasenyakatho, ibanga kanye nobude bokufuduka kwakukude kubantu be-MB kunakwabantu be-RB. Ibanga kanye nobude bokundiza kokuqala ngesikhathi sokufuduka ngasenyakatho kwakukude kubantu be-MB kunakwabantu be-RB, okuphakamisa ukuthi abantu be-MB bafaka uphethiloli omningi ngaphambi kokuhamba ezindaweni ezingazaleli ukuze basekele ukundiza kwabo okude okungami. Abantu be-RB babonise ukuxhumana okubuthakathaka kokufuduka (izindawo zokuzalela ezisakazeka ebangeni elingama-longitude angu-60) kunabantu be-MB (izindawo zokuzalela ezigxile ebangeni elingama-longitude angu-5 eMpumalanga Ekude yeRussia). Uma kuqhathaniswa nabantu be-MB, abantu be-RB babencike kakhulu ezindaweni zokuma oLwandle Oluphuzi kanye nezifunda ezisogwini eShayina, lapho indawo yokuhlala yamaza ilahlekelwe kakhulu khona. Kodwa-ke, inani le-RB landa kanti inani le-MB lancipha eminyakeni edlule, okuphakamisa ukuthi ukulahlekelwa yindawo yokuhlala yamaza ezindaweni zokuma kwakunomthelela omncane kubantu be-Whimbrel, abangasebenzisa izinhlobo ezahlukene zokuhlala. Izitayela ezahlukene phakathi kwabantu zingase zibe ngenxa yamazinga ahlukene okucindezela kokuzingela ezindaweni zabo zokuzalela. Iziphetho Lolu cwaningo luqokomisa ukuthi izinyathelo zokulondoloza zingathuthukiswa ngokuqonda umjikelezo wokuphila waminyaka yonke wokunyakaza kwezinhlobo eziningi zezinyoni ze-Whimbrel kanye nezinye izinyoni ezifudukayo.
