Kukhazikika kwa khalidwe la agalu a raccoon (Nyctereutes procyonoides) kumapereka chidziwitso chatsopano pa kayendetsedwe ka nyama zakuthengo m'mizinda ya Shanghai, China

Mitundu (ya mleme):agalu a raccoon

Chidule:

Pamene kukula kwa mizinda kumaika nyama zakuthengo m'mavuto atsopano komanso mavuto azachilengedwe, mitundu yomwe imasonyeza khalidwe labwino imaonedwa kuti ikhoza kukhala m'mizinda ndikusintha malinga ndi malo okhala mumzinda. Komabe, kusiyana kwa makhalidwe a anthu okhala m'mizinda ndi m'madera akumidzi kumabweretsa mavuto osaneneka pa njira zachikhalidwe zoyendetsera nyama zakuthengo zomwe nthawi zambiri zimalephera kuganizira zosowa za mtundu wina kapena kuchepetsa mikangano pakati pa anthu ndi nyama zakuthengo chifukwa cha kusintha kwa khalidwe la nyama chifukwa cha kusokonezeka kwakukulu kwa anthu. Pano, tikufufuza kusiyana kwa malo okhala, ntchito za diel, mayendedwe, ndi zakudya za agalu a raccoon (Nyctereutes procyonoides) pakati pa madera okhala ndi malo okhala ndi malo okhala m'nkhalango ku Shanghai, China. Pogwiritsa ntchito deta yotsata GPS kuchokera kwa anthu 22, tapeza kuti malo okhala agalu a raccoon m'madera okhala (10.4 ± 8.8 ha) anali ochepa ndi 91.26% kuposa omwe ali m'mapaki ankhalango (119.6 ± 135.4 ha). Tapezanso kuti agalu a raccoon m'madera okhala anthu anali ndi liwiro lochepa kwambiri loyenda usiku (134.55 ± 50.68 m/h) poyerekeza ndi anzawo a m'nkhalango (263.22 ± 84.972 m/h). Kusanthula kwa zitsanzo 528 za ndowe kunawonetsa kuti anthu amadya kwambiri zosakaniza kuchokera ku chakudya cha anthu m'madera okhala anthu (χ2 = 4.691, P = 0.026), zomwe zikusonyeza kuti njira zopezera chakudya cha agalu a raccoon m'mizinda zimasiyana ndi kuchuluka kwa anthu m'nkhalango chifukwa cha kupezeka kwa chakudya cha anthu chotayidwa, chakudya cha amphaka, ndi zinyalala zonyowa m'madera okhala anthu. Kutengera ndi zomwe tapeza, tikupereka njira yoyendetsera nyama zakuthengo m'madera okhala anthu ndipo tikupereka lingaliro losintha kapangidwe kamene kali m'madera okhala anthu. Zotsatira zathu zikugogomezera kufunika kwa maphunziro a khalidwe la nyama zakuthengo pa kasamalidwe ka zamoyo zosiyanasiyana m'mizinda ndikupereka maziko asayansi ochepetsera mikangano pakati pa anthu ndi nyama zakuthengo m'mizinda m'dera lathu lophunzirira.
