Zomwe zili bwino zimapulumutsa nyama zam'madzi

Nyama zina za m’madzi za m’nyanja zikuchira kwambiri chifukwa cha ntchito yosamalira bwino zachilengedwe. Kumbuyo kwa zoyesayesa izi ndi deta yabwinoko. Mwa kudzaza mipata m’chidziŵitso chathu cha kuchuluka kwa nyama za m’nyanja ndi mmene zimayendera, asayansi akutulukira zenizeni za mmene zinthu zilili. Bwino deta kumapangitsa kukhala kosavuta kulenga ogwira kuchira mapulogalamu.

Chithunzi chamakono

Nyama zam'madzi ndi gulu lotayirira la mitundu pafupifupi 127 kuphatikiza nyama monga anamgumi, ma dolphin ndi zimbalangondo za polar. Malinga ndi lipoti mu Public Library of Science (PLOS) lomwe lidawunika kuchira kwa nyama zam'madzi, zamoyo zina zomwe zatsika ndi 96 peresenti zachira ndi 25 peresenti. Kuchira kumatanthauza kuti chiwerengero cha anthu chawonjezeka kwambiri kuyambira pamene kuchepa kwawo kunalembedwa. Lipotili likuwonetsa kufunika kounikiridwa bwino kwa kuchuluka kwa nyama zam'madzi komanso kusonkhanitsa deta yodalirika ya kuchuluka kwa anthu kuti asayansi athe kupanga ziwerengero zabwino za kuchuluka kwa anthu ndikupanga mapulogalamu owongolera kuchuluka kwa anthu omwe akugwira ntchito.

Momwe deta imathetsera bwino

Pakafukufuku wofalitsidwa mu PLOS, asayansi adagwiritsa ntchito njira yatsopano yowerengera yomwe idawalola kuyerekeza momwe anthu ambiri amakhalira molondola. Zatsopano ngati izi zimalola asayansi kuchotsa zofooka zomwe zimaperekedwa ndi mipata ya data. Asayansi akuyendanso pang'onopang'ono kuchokera kumadera a m'mphepete mwa nyanja kupita kunyanja yakuya, kuti athe kuwona bwino kayendedwe ka nyama zam'madzi. Komabe, kuti ayang'anire molondola kuchuluka kwa anthu akunyanja, asayansi ayenera kusiyanitsa pakati pa mitundu yosadziwika bwino (mitundu yofanana) kuti zikhale zosavuta kusonkhanitsa zambiri zolondola pa iwo. Kuderali, zatsopano zikupangidwa kale.

Kumvetsera pa zinyama zam'madzi

Ma algorithms opangidwa mwamakonda adagwiritsidwa ntchito kumvetsera phokoso la pansi pamadzi maola 57,000 kuti apeze nyimbo za anamgumi abuluu omwe ali pangozi. Anthu awiri atsopano a blue whale adapezeka pogwiritsa ntchito ukadaulo wamakono komanso zidziwitso zatsopano zamayendedwe awo. Mosiyana ndi zikhulupiriro zakale, anamgumi abuluu a ku Antarctic amakhalabe pagombe la South Australia chaka chonse ndipo zaka zina samabwerera kumalo awo odyetserako krill. Poyerekeza ndi kumvetsera kuyitana kwa chinsomba chilichonse payekhapayekha, pulogalamu yodziwikiratu imapulumutsa nthawi yochuluka yokonza. Chifukwa chake, pulogalamuyi idzakhala yofunika kwambiri m'tsogolomu poyang'ana phokoso la zinyama zam'madzi. Kugwiritsa ntchito umisiri mwaluso n'kofunika kwambiri kuti tipeze zambiri zokhudza kuchuluka kwa zinyama zam'madzi chifukwa zimathandiza asayansi kufufuza bwino zomwe zingatheke kuteteza zinyama.
