Malinga ndi ofufuza, akamba akuluakulu a m’madzi opanda mchere amalankhulana wina ndi mnzake komanso anawo amalankhulana pogwiritsa ntchito mawu osachepera 6.
Pogwiritsa ntchito maikolofoni ndi ma hydrophone, asayansi anatha kujambula mawu oposa 250 opangidwa ndi akamba a mumtsinje. Podocnemis expansa. Kenako adawasanthula m'mitundu isanu ndi umodzi yomwe imagwirizana ndi machitidwe ena a akamba.
"Tanthauzo lenileni la phokosoli silikudziwika ... Komabe, timakhulupirira kuti akambawo akusinthanitsa chidziwitso," adatero Dr. Camila Ferrara, yemwe adachita nawo phunziroli. "Timakhulupirira kuti phokoso limathandizira nyama kugwirizanitsa zochita zawo panthawi ya mazira," anawonjezera Ferrara. Phokoso la akambawo linkasiyanasiyana pang’ono malinga ndi zimene nyamazo zinkachita panthawiyo.
Mwachitsanzo, kamba ankaimba phokoso lapadera akuluakulu akamawoloka mtsinje. Akamba ena onse atasonkhana m’mphepete mwa nyanja pamene ankapanga zingwe zomangira zingwezo, anatulutsa phokoso lina. Malinga ndi kunena kwa Dr. Ferrara, akamba aakazi amagwiritsa ntchito mawu olira polozera ana awo ongobadwa kumene m’madzi ndi kubwerera kumtunda. Popeza akamba ambiri amakhala ndi moyo zaka zambiri, asayansi amati akamba aang’ono pa moyo wawo amaphunzira kulankhulana pogwiritsa ntchito mawu a achibale odziwa zambiri.
