Abstract:

Allee mhedzisiro, inotsanangurwa sehukama hwakanaka pakati pechikamu chekusimba uye kuwanda kwehuwandu hwevanhu (kana saizi), inoita basa rakakosha mukusimba kwevadiki kana vakaderera. Kuunzazve chave chishandiso chinoshandiswa zvakanyanya nekurasikirwa kunoramba kuripo kwezvipenyu zvakasiyana-siyana. Sezvo vanhu vakadzoserwa zvakare vari vashoma, maAllee mhedzisiro anowanzo kuvepo kana mhuka iri kutora nzvimbo itsva. Nekudaro, humbowo hwakananga hwehumwe density-dependence inoshanda muvanhu vakaunzwazve haiwanzo. Kuti tinzwisise basa reAllee mhedzisiro mukugadzirisa mushure mekuburitswa kwehuwandu hwehuwandu hwemhando dzakaunzwa patsva, takaongorora data-yakatevedzana data yakaunganidzwa kubva kune maviri ega ega ega eiyo akadzoserwa Crested Ibis (Nipponia nippon) muShaanxi Province, China (Ningshan neQianyang Counties). Takaongorora hukama hunogona kuitika pakati pehukuru hwevanhu uye (1) kurarama nekuberekana, (2) huwandu hwekukura kwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hweAllee muhuwandu hwemabis akadzokororwa. Zvigumisiro zvakaratidza kuti kuitika panguva imwe chete kwechikamu cheAllee migumisiro mukupona uye kubereka zvakaonekwa, asi kuderedzwa kwehupenyu hwevanhu vakuru uye mukana wekubereka kwevakadzi kwakatungamirira kuhuwandu hwevanhu veAllee muhuwandu hweQianyang ibis, izvo zvingave zvakakonzera kuderera kwevanhu. Mukufanana, mate-kugumira uye predation sezvingabvira nzira dzekutanga dzeAllee mhedzisiro dzakaratidzwa. Zvatikawana zvakapa humbowo hwehuwandu hweAllee mhedzisiro muhuwandu hwakadzoserwa uye nzira dzekuchengetedza kuchengetedza kubvisa kana kuderedza simba reAllee mhedzisiro mukudzoreredzwa kweramangwana rezvipenyu zviri mungozi zvakarongwa, kusanganisira kuburitswa kwenhamba yakawanda yevanhu, kuwedzera kwekudya, uye kutonga kwezvikara.
