Idatha engcono ilondoloza izilwane ezincelisayo zasolwandle

Ezinye izilwane ezincelisayo zasolwandle zilulame kakhulu ngenxa yemizamo eyimpumelelo yokongiwa kwemvelo. Ngemuva kwale mizamo kunedatha engcono. Ngokugcwalisa izikhala olwazini lwethu ngezilwane ezincelisayo zasolwandle kanye nezindlela zazo zokuhamba, ososayensi bathola iqiniso lesimo sabo. Idatha engcono ikwenza kube lula ukudala izinhlelo zokutakula ezisebenza kahle kakhulu.

Isithombe samanje

Izilwane ezincelisayo zasolwandle ziyiqoqo elixegayo lezinhlobo ezingaba ngu-127 ezihlanganisa nezilwane ezinjengemikhomo, amahlengethwa namabhere asezindaweni ezishisayo. Ngokuvumelana ne umbiko ku-Public Library of Science (PLOS) ohlole ukutholakala kwezilwane ezincelisayo zasolwandle, ezinye izinhlobo eziye zehla ngamanani ngamaphesenti angu-96 ziye zalulama ngamaphesenti angu-25. Ukuthola kabusha kusho ukuthi inani labantu likhule kakhulu kusukela ukwehla kwabo kwarekhodwa. Lo mbiko ugqamisa isidingo sokuqapha okuthuthukisiwe kwezilwane ezincelisayo zasolwandle kanye nokuqoqwa kwedatha yabantu ethembeke kakhudlwana ukuze ososayensi bakwazi ukwenza izilinganiso ezingcono zokuthambekela kwenani labantu futhi bakhe izinhlelo zokulawula inani labantu ezizosebenza nakanjani.

Idatha ikuxazulula kangcono kangakanani

Ocwaningweni olushicilelwe ku-PLOS, ososayensi basebenzise imodeli yezibalo entsha ebavumela ukuthi balinganisele amathrendi omphakathi ngokunemba okukhulu. Ukuqamba okusha okufana nalokhu kuvumela ososayensi ukuthi basuse ubuthakathaka obethulwa izikhala kudatha. Ososayensi nabo banyakazisa ukuqapha ukusuka ezindaweni ezisogwini kuya ekujuleni kolwandle, okuvumela ukubhekwa okunembe kakhudlwana kokuhamba kwezilwane ezincelisayo zasolwandle. Nokho, ukuze kuqashwe ngokunembile inani labantu abangaphesheya kwezilwandle, ososayensi kufanele bahlukanise phakathi kwezibalo ezifihlekile (izinhlobo ezibukeka ngokufanayo) ukuze kube lula ukuqoqa ulwazi olunembile ngazo. Kuleyo ndawo, sekuvele kwenziwa izinto ezintsha.

Ukulalela izilwane ezincelisayo zasolwandle

Ama-algorithms okuthola aklanywe ngokwezifiso asetshenziselwa ukulalela amahora angu-57,000 omsindo wolwandle ongaphansi kwamanzi ukuze kutholwe izingoma zama-blue whales asengozini yokushabalala. Kutholwe abantu ababili abasha bemikhomo eluhlaza okwesibhakabhaka kusetshenziswa lobu buchwepheshe obusha kanye nemininingwane emisha ngokuhamba kwabo. Ngokuphambene nenkolelo yangaphambili, imikhomo eluhlaza yase-Antarctic ihlala ngasogwini lwaseNingizimu Australia unyaka wonke futhi eminye iminyaka ayibuyeli ezindaweni zayo zokudla ezinothile nge-krill. Uma kuqhathaniswa nokulalela ucingo lomkhomo ngamunye ngamunye, uhlelo lokuthola lusindisa inani elikhulu lesikhathi sokucubungula. Kanjalo, lolu hlelo luzoba lubucayi esikhathini esizayo lokubheka imisindo yezilwane ezincelisayo zasolwandle. Ukusetshenziswa okusha kobuchwepheshe kubalulekile ekuqoqeni idatha engcono ngenani lezilwane ezincelisayo zasolwandle ngoba kusiza ososayensi bahlole kangcono ukuthi yini engenziwa ukuze kuvikelwe izilwane.
