Cov lus tshawb fawb tau tshaj tawm nyob rau hauv cov phau ntawv ceev xwm txheej siab-tech (Q1) ib puag ncig tshuaj xyuas. "Los kwv yees trawl macrophaunais thiab ib qho ntawm Arctic hiav txwv, nrog rau sab qaum teb ntawm Pacific Ceg ntawm Vniro (Tinro), hais tias ib tus sau phau ntawv , ib tug neeg ua haujlwm ntawm lub koom haum ntawm Oceanology ntawm Lavxias Academy of Sciences, Vniro thiab B.GU, Alexey Orlov.
- Tag nrho cov ntawv txheeb xyuas 459 kev tshawb fawb txog kev tshawb fawb (ntawm qhov tob ntawm tsib mus rau 2,200 metres) nyob rau lub sijhawm los ntawm 1977 mus rau 2014. Thaj chaw ntawm txoj kev tshawb no tau tshaj 25 lab square kilometers. Daim Ntawv Teev Npe Nkag mus rau 1541 hom, rau txhua tus uas qhia cov khoom tawm khoom thiab coj mus muag.
Kev tshawb xyuas ntawm Macrofauna qhia tias yuav luag 20 feem pua ntawm cov hom ntes tsis muaj tus nqi nuv ntses, txog 50 feem pua yog pheej yig lossis pheej yig heev. Tsuas yog 3.3 feem pua ntawm hom yog kim thiab kim heev, lawv tus lej hauv kev ntes nce los ntawm Qaum teb mus rau sab qab teb.
Txog 500 hom - tsis yog cov khoom siv me me, feem ntau yog cov ntses me thiab invertebrates, baliver mollusks, ascies, jellyfish, thiab lwm yam). Lawv cov biomass dav dav yog ntau zaus ntau dua li cov peev txheej siv roj ntsha siv los ntawm cov peev txheej lom neeg.
"Tam sim no, kev lag luam tsis txaus siab rau cov hom no rau ntau yam," hais tias tus kws tshawb fawb ntawm IU Ras, Vniro thiab B.GU, Alexey Orlov. - Ib qho ntawm cov ntsiab lus tseem ceeb yog qhov simlooj ntawm cov tsiaj no rau kev ua lag luam hauv tsev. Piv txwv li, Skates, ntses, cov cua nab, cov pa dej hiav txwv, cov neeg sawv cev "cov neeg sawv cev" cov khoom lag luam zoo hauv cov neeg Esxias. Nyob rau hauv Lavxias coverves, lawv tsis zoo li tau tshwm sim, tab sis yuav rho tawm lawv nrog kev xa tawm mus rau Nyiv, Tuam Tshoj, Kauslim thiab lwm lub teb chaws ntawm East Asia tej zaum yuav muaj txiaj ntsig zoo. "
Lwm qhov kev cuam tshuam yog tias cov khoom siv me me ntawm cov tuam txhab loj thiab ua rau muaj txiaj ntsig me me thiab pab txhawb rau kev lag luam me thiab nruab nrab hauv cov ntses kev lag luam.
"Tsis muaj tsawg dua qhov tsis muaj kev txwv cov ntses ntses yog qhov tsis muaj cov ntaub ntawv ntawm cov khoom tsis muaj kev paub tsis paub tsis tau paub, kev lag luam tus nqi thiab muag khoom lag luam, txuas ntxiv mus rau Alexey Markovich. - Qhov no tsuas yog ua haujlwm ntawm cov khoom siv nuv ntses kom paub cov khoom siv roj ntsha uas tsis siv (WBD) thiab xa cov neeg nuv ntses cov ntaub ntawv tsim nyog hauv daim ntawv ntawm cov lus qhia tswv yim. Tsuas yog hauv qhov no, cov tswv yim tseem ceeb ntawm peb tsab xov xwm tau muaj. "
Nws yog tsim nyog sau tias cov npe tshaj tawm tuaj yeem siv tsis tsuas yog kev siv cov teebmeem ib puag ncig, tab sis kuj muaj kev ua paug rau hauv cov txheej txheem ntawm hydroppogen, tab sis kuj muaj kev sib tsoo ntawm nuclear reactors, poaching thiab lwm yam).
Raws li cov kws sau ntawv ntawm tsab xov xwm, tam sim no kev puas tsuaj tshwm sim rau ib puag ncig yog xam raws li txoj cai ntawm kev cai lij choj tsis tau txhais los ntawm txoj cai, thiab cov nyiaj tau muaj nyob rau ntawm qhov tseem ceeb tshaj plaws Cov khoom nyob rau hauv kev ua txhaum uas feem ntau tshwm sim feem ntau (crabs, hiav txwv hedgehogs, sturgeon, salmon thiab hom zoo sib xws).
Meanwhile, vim yog kev puas tsuaj ntawm kev ua kom zoo nkauj (roj nchuav, tag nrho cov neeg muaj kev puas tsuaj uas tsis muaj kev puas tsuaj los ntawm tus nqi ntawm txhua txoj kev siv roj ntsha tsis tau.
Cov npe luam tawm tau muab cov kev hloov ib puag ncig ib puag ncig hauv kev txheeb xyuas qhov kev puas tsuaj rau ib puag ncig ntawm kev ua kom muaj kev puas tsuaj rau ib puag ncig thiab kev siv tsis tau ntawm cov dej hiav txwv.
