Imiphumela yocwaningo ishicilelwa ku-High-Tech Journal (Q1) Ukubuyekezwa Kwemvelo. "Ukulinganisa i-Trawl Macrophaun emibili yaseMpumalanga Ekude noLwandle i-Arctic, kanye nengxenye esenyakatho yePacific, idatha ekwakhiweni kwe-Trawros Catch of the Pacific Branch of Vniro (Tinro), kusho omunye wababhali be-athikili , isisebenzi seSikhungo Sokulwa Kwe-Ocealoology of the Russian Academy of Science, Vniro no-B.GU, Alexey Orlov.
- Ingqikithi ihlaziye ama-459 izinhlolovo zesayensi zamaNkantolo Zocwaningo (ekujuleni kwamamitha amahlanu kuya kwangama-2 200) ngesikhathi kusuka ngo-1977 kuya ku-2014. Indawo yocwaningo yayingaphezu kwamakhilomitha-skwele ayizigidi ezingama-25. Uhlu lokuhlola lufake izinhlobo zezinhlobo ezingama-1541, kulowo nalowo okhombisa umphumela womkhiqizo kanye nezindleko zezentengiso.
Ukucwaningwa kwamabhuku kweMacrofauna kubonise ukuthi cishe amaphesenti angama-20 ezinhlobo ezibanjwa yiTrawl angenalo inani lokudoba, cishe amaphesenti angama-50 ayeshibhile noma ashibhile kakhulu. Amaphesenti ama-3.3 kuphela ezinhlobo abiza kakhulu futhi abiza kakhulu, inombolo yawo ekubanjweni kokubamba esuka enyakatho aye entshonalanga.
Cishe ama-500 izinhlobo - izinsiza ezingapheli, ikakhulukazi lezi zinhlanzi ezincane nama-invertebrates (i-bivalve kanye ne-burglar mollusks, izibungu zasolwandle, ama-ascessfish, njalonjalo). I-biomass yabo ejwayelekile izikhathi eziningi kunezinsizakusebenza zemvelo ezisetshenziswa yizinsiza zemvelo.
"Njengamanje, imboni ayibonisi isithakazelo kulezi zinhlobo zezizathu eziningi," kusho usosayensi we-IU RAS, VNIRO naseB.GU, u-Alexey Orlov. - Enye yezinto eziphambili ukugcwala kwalezi zinhlobo zemakethe yasekhaya. Isibonelo, ama-skates, oshaka, izikelemu zasolwandle, ama-ranks ama-mantis, ama-ascides, i-jellyfish nabanye abamele "ama-exotic" wezilwane zasolwandle basebenzisa izimakethe eziphakeme ezimakethe zase-Asia, ikakhulukazi eChina. Emashalofini aseRussia, akunakwenzeka ukuthi avele, kepha ukuze akhiphe ngaphandle kwamanye amazwe eJapan, eChina, eKorea nakwamanye amazwe aseMpumalanga Asia angaba nenzuzo enkulu impela. "
Enye into ethonya ukuthi amavolumu amancane okubanjwa abhekelwa yizinkampani ezinkulu, kepha ukudoba okunjalo kungaba inzuzo enkulu ezinhlanganweni ezincane futhi kufake isandla ekuthuthukisweni kwamabhizinisi amancane naphakathi embonini yezinhlanzi.
"Akunakubangela okubaluleke kangako kokudoba ukudoba ukuswela ulwazi phambi kwezinsiza zamahhala ezingazi, izindlela zazo zobuchwepheshe, izindlela zokukhiqiza, izimakethe zemakethe kanye nezimakethe zokuthengisa, ziyaqhubeka no-Alexey Markovich. - Lona nje umsebenzi wezokudoba ukukhomba izinsiza zemvelo ezingasetshenziswanga (WBD) futhi udlulise kubadobi imininingwane edingekayo ngohlobo lweziphakamiso ezisebenzayo. Kulokhu nje, umbono oyisisekelo we-athikili yethu wabalwa. "
Kuyaqapheleka ukuthi uhlu olushicilelwe lungasetshenziswa hhayi kuphela ukuphathwa kwe-biorsource olusebenzayo, kepha futhi ukuhlola ukulimala kwemvelo okubangelwa imiphumela ye-anthropogenic (kufaka phakathi ukungcoliswa kwenqubo ye-hydropogen, ingozi yokuzingela kanye nokunye).
Ngokusho kwababhali be-athikili, okudangala njengamanje okubangelwa imvelo kubalwa ngesisekelo sezenzo zomnyango, lapho inani lemvelo eyodwa noma enye into yezilwane zasendle ichazwa ngomthetho, futhi idatha yenani iyatholakala kakhulu Izinto maqondana nokuthi ukwephulwa kwalokhu kwenzeka kaningi kakhulu (ama-crabs, uFrepang, ama-hedgehogs, i-sturgeon, ama-salmon kanye nezinhlobo ezifanayo).
Ngaleso sikhathi, ngenxa yezinhlekelele ze-technogenic (ukuchitheka kwamafutha, ukuphuma kwamafutha, ukungcoliswa kwezimboni), lonke inani le-ecosystem liyaluhlupheka kaningi, futhi lihlole lokho okunjalo ngaphandle kolwazi ngenani lezinhlobo zemvelo akunakwenzeka.
Uhlu olushicilelwe lunganikeza izakhiwo zemvelo kwithuluzi elingezekile ekuhlolweni komonakalo emvelweni ngenxa yemiphumela ye-anthropogenic, kubandakanya nokuzingela nokuxhashazwa okungenangqondo kwe-miorlource yasemanzini.
