Kuyesera kwatsopano kuti apeze mtundu wa moyo womwe ulipo pansi pa nyanja kwadzetsa malingaliro onena za chiyembekezo cha chirombo chachikulu kwambiri chobisalira mkatikati mwa nyanja. Kodi ndi nsomba zazikulu kapena nyamayi? Kapena china chake chowopsa kwambiri kuposa momwe timaganizira?
Pakadali pano, tangofufuza pafupifupi 5% ya nyanja zapadziko lonse lapansi, zomwe zimakhudza 70% yapadziko lapansi. Anthu nthawi zonse akhala akuchita chidwi ndi zinsinsi zomwe zili mkatikati mwa madzi.
Kuyesera Kwakukulu kwa Gator
Akatswiri a zamoyo za m'madzi Craig McClain ndi Clifton Nunnally ochokera ku Louisiana Universities Marine Consortium akufuna kuti amvetsetse bwino zomwe zikuchitika pansi panyanja, adayesa dzina loti Kuyesera Kwakukulu kwa Gator, zomwe zinatulutsa zotsatira zosangalatsa.
Ofufuzawo adayika buffet yazinthu zodabwitsa zapanyanja zomwe zimaphatikizaponso nyama zankhondo zitatu zakufa, zomangirizidwa zolemera. Iwo anali ndi chidwi chofuna kuona momwe mitembo yawo idzawonongedwere ndi zolengedwa zobisalira pansi pa nyanja.
"Kuti tifufuze malo osungira chakudya mkatikati mwa nyanja, tidayika ma alligator atatu omwe adafa pafupifupi 6,600 pansi ku Gulf of Mexico masiku 51," Anatero Clifton Nunnally wochokera ku Louisiana University.
Zomwe zinatsatira zinali zodabwitsa kwambiri
Gator woyamba adadyedwa mkati mwa maola 24 atagunda pansi panyanja. Nthawi yomweyo adalandiridwa ndi isopods zazikulu, zomwe malinga ndi Nunnally, zili ngati ziwombankhanga zakuya. Kenako, obisala ena ngati amphipods, ma grenadiers ndi nsomba zina zakuda zosadziwika, sanadziwike nawo. Ma isopods adang'amba cholengedwa chofulumira kuposa momwe asayansi amayembekezera, ndikudya mkati.
Ng'ombe yachiwiri idadyedwa nthawi yayitali. Pambuyo masiku 51, onse omwe adatsalira anali mafupa ake, omwe anali ndi mtundu wofiyira.
"Ameneyo adatidabwitsadi. Panalibe ngakhale sikelo ngakhale chithunzithunzi chotsalira pa mtembo, ” McClain adauza Atlas Obscura. Kenako gululi linatumiza mafupawo kwa a Greg Rouse, katswiri wa zamoyo zam'madzi ku Scripps Institution of Oceanography, kuti akawunikenso.
Rouse adapeza kuti gator adathyoledwa matangadza ndi mtundu watsopano wa nyongolotsi zomwe zimadya mafupa mumtundu wa Osedax. Aka kanali koyamba kuti membala wa Osedax apezeke ku Gulf of Mexico, malinga ndi a McClain. Ofufuzawo kenako anayerekezera DNA yomwe yangopezekayo ndi mitundu yodziwika kale ya Osedax, ndikuzindikira kuti apeza mitundu yatsopano yamtunduwu.
Ngakhale kutulukira kwatsopano kwa mtundu watsopano wa Osedax, inali alligator yachitatu yomwe idapangitsa asayansi kukhala osokonezeka kwambiri. Pochezera komwe gator wachitatu adaponyedwa, amangowona kukhumudwa kwakukulu mumchenga - nyamayo idazimiririka. Kenako gululi linafufuza malo oyandikana nalo koma silinapeze chochita cha alligator. Komabe, anapeza kulemera kwa gator, komwe kunali pafupifupi 10 mita kuchokera pamalopo.
Izi zikutanthawuza kuti chilombo chomwe chinasesa gator chinali chachikulu mokwanira kuti chimenye chonsecho ndikukoka kulemera kwake komweko. Gululi likukayikira nyamayo kuti ndi squid yayikulu kapena shaki yayikulu yomwe ikudikirira kuti ipezeke. "Sindinapezebe squid yemwe angadye nyama yanyama yonse, ndipo sindikufuna kukhala m'ngalawayo ngati titazindikira."
Ofufuza awiriwa adadabwa ndi zotsatirazi, komanso adakhutira ndi kuyesaku. Zachidziwikire, akukonzekera kuchita zoyeserera zambiri kutsatira zotsatirazi.
Kodi nyama yodabwitsayi ingakhale Kraken - chilombo chodabwitsa cham'madzi chachikulu kwambiri komanso mawonekedwe ofanana ndi cephalopod mu miyambo yaku Scandinavia? Kapena china chake chomwe sitinaganizepopo?
Ngati mukufuna kudziwa za Kraken ndi zolengedwa zodabwitsa za m'nyanja zakuya, werengani Nkhaniyi yokhudza chilombo chodabwitsa cha USS Stein. Pambuyo pake, werengani za izi Zolengedwa za 44 zodabwitsa kwambiri padziko lapansi. Mapeto ake, dziwani izi 14 zomveka zodabwitsa zomwe sizikudziwika mpaka pano.
