Ingaruka za Allee, zisobanurwa nk'isano nziza iri hagati y'ubuzima bw'ibice n'ubucucike bw'abaturage (cyangwa ingano), zigira uruhare runini mu mihindagurikire y'abaturage bato cyangwa bake. Gusubiza mu buzima busanzwe byabaye igikoresho gikoreshwa cyane hamwe no gutakaza urusobe rw'ibinyabuzima. Kubera ko ubwoko bwasubijwe mu buzima busanzwe ari buto, ingaruka za Allee zikunze kubaho iyo ubwoko bumwe burimo kwigarurira ahantu hashya. Ariko, ibimenyetso byerekana ko ubucucike bwiza bukora ku bwoko bwasubijwe mu buzima busanzwe ni gake cyane. Kugira ngo dusobanukirwe uruhare rw'ingaruka za Allee mu kugenzura imihindagurikire y'ubwoko bwasubijwe mu buzima busanzwe nyuma yo kurekurwa, twasesenguye amakuru y'uruhererekane rw'igihe yakusanyijwe mu moko abiri y'inyamaswa zo mu bwoko bwa Crested Ibis (Nipponia nippon) zo mu Ntara ya Shaanxi, mu Bushinwa (uturere twa Ningshan na Qianyang). Twasuzumye isano ishobora kuba iri hagati y'ingano y'abaturage na (1) igipimo cyo kubaho no kororoka, (2) igipimo cy'ubwiyongere bw'abaturage kuri buri muntu ku bijyanye n'uko ingaruka za Allee zibaho mu bwoko bwa ibis zongeye kwinjizwa mu buzima busanzwe. Ibisubizo byagaragaje ko ingaruka za Allee ku binyabutabire mu kubaho no kororoka zagaragaye icyarimwe, mu gihe kugabanuka kw'ingaruka za Allee ku bantu bakuru no ku bagore byatumye habaho ingaruka za Allee ku baturage mu bwoko bwa Qianyang ibis, bishobora kuba byaratumye umubare w'inyamaswa zigwa. Muri ubwo buryo, hagaragajwe uburyo bwo gutangiza ingaruka za Allee ku bagabo n'abagore. Ibyavuye mu bushakashatsi bwacu byagaragaje ibimenyetso by'ingaruka nyinshi za Allee ku baturage basubijwe mu miryango ndetse n'ingamba zo kubungabunga ibidukikije kugira ngo hakorwe cyangwa hagabanywe imbaraga za Allee mu kongera kubyara inyamaswa ziri mu kaga mu gihe kizaza, harimo kurekura umubare munini w'inyamaswa, kongera ibiryo, no kurwanya inyamaswa zirya inyamaswa.
