Iplastiki yokuziphatha yezinja ze-raccoon (i-Nyctereutes procyonoides) inikezela ngolwazi olutsha kulawulo lwezilwanyana zasendle ezidolophini kwi-metropolis yaseShanghai, eChina.

Iintlobo(ilulwane):izinja raccoon

Inkcazo:

Njengoko ukuhlala kwabantu ezidolophini kubhentsisa izilwanyana zasendle kwiimeko eziceli-mngeni ezintsha kunye noxinzelelo lokusingqongileyo, iintlobo zezilwanyana ezibonisa umgangatho ophezulu wokuziphatha kweplastikhi zithathwa ngokuba ziyakwazi ukwenza iikholoni kunye nokuziqhelanisa nemekobume yasezidolophini. Nangona kunjalo, iyantlukwano kwindlela yokuziphatha kwabantu abahlala kwimimandla yasezidolophini nakwimimandla yasezidolophini ibeka imingeni engazange ibonwe ngaphambili kwiindlela zemveli kulawulo lwezilwanyana zasendle ezihlala zisilela ukuqwalasela iimfuno zohlobo oluthile okanye ukunciphisa ungquzulwano phakathi kwabantu nezilwanyana zasendle ngenxa yotshintsho kwindlela yokuziphatha kweentlobo ekuphenduleni uphazamiseko olumandla lwabantu. Apha, siphanda iiyantlukwano kuluhlu lwekhaya, umsebenzi we-diel, ukuhamba, kunye nokutya kwezinja ze-raccoon (Nyctereutes procyonoides) phakathi kwezithili zokuhlala kunye neendawo zokuhlala zepaki e-Shanghai, e-China. Ukusebenzisa idatha yokulandelela i-GPS evela kubantu abangama-22, sifumanisa ukuba uluhlu lwamakhaya lwezinja ze-raccoon kwizithili zokuhlala (10.4 ± 8.8 ha) zazingaphantsi kwe-91.26% kunezo zipaki zehlathi (119.6 ± 135.4 ha). Kwakhona sifumanisa ukuba izinja raccoon kwizithili zokuhlala ebonisa isantya kakhulu esezantsi intshukumo ebusuku (134.55 ± 50.68 m/h) xa kuthelekiswa noogxa babo ipaki ihlathi (263.22 ± 84.972 m/h). Uhlalutyo lweesampulu ze-fecal ezingama-528 lubonise ukuthathwa okuphezulu kakhulu kwezithako ezivela kukutya kwabantu kwizithili ezihlala abantu (χ2 = 4.691, P = 0.026), nto leyo ebonisa ukuba amaqhinga okutya izinja ze-raccoon zasezidolophini zahlukile kuluntu lwepaki yehlathi ngenxa yobukho bokutya okulahliweyo kwabantu, ukutya kwekati, kunye nenkunkuma emanzi kwizithili zokuhlala. Ngokusekelwe kwiziphumo zethu, siphakamisa isicwangciso solawulo lwezilwanyana zasendle esekwe kuluntu kwaye sicebisa ukuguqula uyilo lwangoku lwezithili zokuhlala. Iziphumo zethu zigxininisa ukubaluleka kwezifundo zokuziphatha kwezilwanyana ezanyisayo kulawulo lwezityalo nezilwanyana zasezidolophini kwaye zibonelela ngesiseko senzululwazi sokunciphisa ungquzulwano phakathi kwabantu nezilwanyana zasendle kwindawo esingqongileyo yedolophu nangaphaya kwendawo yethu yophononongo.
