Iintlobo (ilulwane):izinja ze-raccoon
Isishwankathelo:
Njengoko ukufudukela ezidolophini kubeka izilwanyana zasendle kwiimeko ezintsha ezinzima kunye noxinzelelo lokusingqongileyo, iintlobo ezibonisa izinga eliphezulu lokuziphatha zithathwa njengezinako ukuhlala kunye nokuziqhelanisa neendawo zasezidolophini. Nangona kunjalo, umahluko kwindlela abantu abahlala kwiindawo zasezidolophini nakwiindawo zasezidolophini uzisa imingeni engakaze ibonwe kwiindlela zemveli zolawulo lwezilwanyana zasendle ezihlala zisilela ukuqwalasela iimfuno zohlobo oluthile okanye ukunciphisa ingxabano phakathi kwabantu nezilwanyana zasendle ngenxa yotshintsho kwindlela abantu abaziphatha ngayo ngenxa yokuphazamiseka okukhulu kwabantu. Apha, siphanda umahluko kwiindawo zokuhlala, umsebenzi we-diel, intshukumo, kunye nokutya kwezinja ze-raccoon (Nyctereutes procyonoides) phakathi kweendawo zokuhlala kunye neendawo zokuhlala zepaki yamahlathi eShanghai, eTshayina. Sisebenzisa idatha yokulandelela i-GPS evela kubantu abangama-22, sifumanisa ukuba iindawo zokuhlala zezinja ze-raccoon kwiindawo zokuhlala (10.4 ± 8.8 ha) zazincinci ngama-91.26% kunezo zikwiipaki zamahlathi (119.6 ± 135.4 ha). Sikwafumanisa ukuba izinja ze-raccoon kwiindawo zokuhlala zibonakalise isantya esiphantsi kakhulu sokuhamba ebusuku (134.55 ± 50.68 m/h) xa kuthelekiswa nezinye iipaki zehlathi (263.22 ± 84.972 m/h). Uhlalutyo lweesampulu zendle ezingama-528 lubonise ukutya okuphezulu kakhulu kwezithako ezivela kukutya kwabantu kwiindawo zokuhlala (χ2 = 4.691, P = 0.026), nto leyo ebonisa ukuba iindlela zokutya kwezinja ze-raccoon zasezidolophini zahlukile kuluntu lweepaki zehlathi ngenxa yokubakho kokutya kwabantu okulahliweyo, ukutya kweekati, kunye nenkunkuma emanzi kwiindawo zokuhlala. Ngokusekelwe kwiziphumo zethu, sicebisa isicwangciso solawulo lwezilwanyana zasendle esisekelwe kuluntu kwaye sicebisa ukuba kutshintshwe uyilo lwangoku lweendawo zokuhlala. Iziphumo zethu zigxininisa ukubaluleka kwezifundo zokuziphatha kwezilwanyana ezincancisayo kulawulo lwezinto ezahlukeneyo zasezidolophini kwaye zibonelela ngesiseko sesayensi sokunciphisa iingxabano phakathi kwabantu nezilwanyana zasendle kwiindawo zasezidolophini ngaphakathi nangaphandle kwendawo yethu yokufunda.
