Ukuhlanganisa idatha yokulandelela yesimanje kanye namarekhodi omlando kuthuthukisa ukuqonda izindawo zokuhlala zasehlobo ze-Eastern Lesser White-fronted Goose Anser erythropus.

Izinhlobo (zezinyoni):I-Lesser White-fronted Goose (i-Anser erythropus)

Ijenali:I-Ecology kanye Nokuziphendukela Kwemvelo

Isifinyezo:

I-Lesser White-fronted Goose (i-Anser erythropus), encane kunazo zonke "ezimpunga", ibhalwe njengesengozini ohlwini olubomvu lwe-IUCN futhi ivikelwe kuzo zonke izifundazwe. Kunezinhlobo ezintathu, kanti ezincane kakhulu ezifundwe ngabantu baseMpumalanga, ezabelwana phakathi kweRussia neShayina. Ukuqhelelana okukhulu kwezindawo zokuzalela kwenza zingafinyeleleki kakhulu kubacwaningi. Njengendlela yokuvakasha, ukulandelela izinyoni kude ezindaweni zasebusika kuvumela ukuhlola indawo yazo yasehlobo. Esikhathini seminyaka emithathu, futhi kusetshenziswa amadivayisi okulandelela e-GPS anembe kakhulu, izilwane eziyishumi nanye ze-A. erythropus zalandelwa kusukela endaweni ebalulekile yasebusika eShayina, kuya ezindaweni zasehlobo, nasezindaweni zokubeka izinyoni enyakatho-mpumalanga yeRussia. Idatha etholwe kulokho kulandelela, eqiniswe yizinhlolovo zomhlaba kanye namarekhodi ezincwadi, yasetshenziswa ukwenza imodeli yokusatshalaliswa kwehlobo kwe-A. erythropus. Nakuba izincwadi zangaphambilini zichaza indawo yasehlobo enamachashaza, imodeli iphakamisa ukuthi indawo yokuhlala yasehlobo ehambisanayo ingenzeka, yize ukubonwa kuze kube manje kungenakukuqinisekisa ukuthi i-A. erythropus ikhona kulo lonke uhla olubonisiwe. Izindawo zokuhlala ezifanele kakhulu zitholakala ogwini loLwandle iLaptev, ikakhulukazi iLena Delta, eYana-Kolyma Lowland, kanye nezindawo ezincane eziphansi zaseChukotka ezinezandiso ezincane zasemfuleni ongasemfuleni ongasemfuleni oseduze nemifula emikhulu njengeLena, i-Indigirka, neKolyma. Amathuba okuba khona kwe-A. erythropus ahlobene nezindawo eziphakeme ngaphansi kwamamitha angu-500 ezinamanzi amaningi, ikakhulukazi izindawo zokuhlala zasemfuleni ongasemfuleni, kanye nesimo sezulu esinemvula efudumele kakhulu cishe ngamamilimitha angu-55 kanye nokushisa okumaphakathi cishe ngo-14°C phakathi kukaJuni-Agasti. Ukuphazamiseka kwabantu nakho kuthinta ukufaneleka kwendawo, ngokuncipha kancane kancane kokuba khona kwezinhlobo zezilwane kuqala cishe ngamakhilomitha angu-160 ukusuka ezindaweni zokuhlala zabantu. Ukulandelela kude izinhlobo zezilwane kungavala igebe lolwazi oludingekayo ukuze kulinganiswe ngokuqinile amaphethini okusatshalaliswa kwezinhlobo ezindaweni ezikude. Ulwazi olungcono ngokusatshalaliswa kwezinhlobo zezilwane lubalulekile ekuqondeni imiphumela emikhulu yemvelo yoshintsho olusheshayo lomhlaba kanye nokusungula amasu okuphatha ukulondolozwa kwemvelo.
