Izinhlobo (Izinyoni):I-Greater White-fronted Goose (Anser albifrons), i-Tundra Bean Goose (Anser serrirostris)

Abstract:

Izilwane zisabela endaweni yazo ezilinganisweni eziningi zendawo ngayinye edinga izindlela zokulondoloza ezehlukene. Izinyoni zasemanzini ziyizinkomba ze-bio eziyinhloko zemvelo yamaxhaphozi esengozini emhlabeni wonke kodwa izindlela zazo zokukhetha indawo yokuhlala enezilinganiso eziningi akuvamile ukuthi zihlolwe. Sisebenzisa idatha yokulandela ngomkhondo ngesathelayithi kanye ne-Maximum entropy modelling, sifunde ukukhethwa kwendawo okuhlala kuyo izinhlobo ezimbili zezinyoni zasemanzini eziwohlokayo, i-Greater White-fronted Goose (Anser Albifrons) kanye ne-Tundra Bean Goose (A. serrirostris), ezikalini ezintathu zendawo: indawo (30, 40, 50 km), i-15, 10, i-roosting (10, 10, 10 km) 5 km). Sacabanga ukuthi ukukhethwa kwendawo yendawo yokuhlala ngokwesilinganiso sezwe kwakusekelwe ikakhulukazi kumamethrikhi wokuma kwezwe uma kuqhathaniswa, kuyilapho izici ezinemininingwane yokwakheka kwezwe zacatshangelwa lapho kukhethwa indawo yokuhlala kanye nezinga lokuzulazula. Sithole ukuthi zombili izinhlobo zezinyoni zasemanzini zincamela izindawo ezinephesenti elikhulu lamaxhaphozi kanye namaxhaphozi esikalini sezwe, ama-waterbodies ahlanganisiwe azungezwe izindawo ezitshaliwe ezisabalele esikalini sokudla, kanye namaxhaphozi axhumene kahle kanye namaxhaphozi aphakathi nendawo axhumeke kahle esikalini se-roosting. Umehluko omkhulu ekukhetheni indawo yokuhlala kulezi zinhlobo ezimbili wenzeka esikalini sezwe kanye nokudla; izici esikalini se-roosting ziyefana. Siphakamisa ukuthi imisebenzi yokongiwa kwemvelo kufanele igxile ekuthuthukiseni ukuhlanganisa nokuxhumana kwezindawo ezihlala amanzi kanye namaxhaphozi, kanye nokuthuthukisa indawo yezitshalo engahlanganisiwe endaweni ezungezile. Indlela yethu ingase iqondise izinqubo zokongiwa kwezinyoni zasemanzini kanye nokuphathwa kwamaxhaphozi ngokunikeza izinyathelo ezisebenzayo zokuthuthukisa ikhwalithi yendawo yokuhlala lapho kubhekwa ushintsho lwemvelo olubangelwa umuntu.
