Uhambo lwesayensi oluseningizimu ekude yeChile lubhale phansi okokuqala ngqa isigaba sezibungu se-icefish (Champsocephalus esox) e-Useless Bay, ogwini lwase-Tierra del Fuego. Irekhodi, elingakaze libonwe lesayensi, latholwa ngesikhathi somkhankaso ngoJulayi 2024 lapho kwenziwa amasampula kusuka kukholomu yamanzi kuya phansi olwandle.
Ukutholwa kunikeza ucezu olulahlekile lokuqonda umjikelezo wempilo yalolu hlobo, okuwukuphela kweqembu laso eliphila ngaphandle kwezwekazi lase-AntarcticNgokusho kwethimba lenkundla, ukuqaphela kuyingxenye yomzamo wokusebenzisana khombisa i-ecosystem kwetheku kusetshenziswa izindlela ezijwayelekile neziqhathaniseka namazwe omhlaba.
Ukutholwa nokuthi kungani kubalulekile
Isibonelo, kancane Amasentimitha angama-2, wabanjwa nge red bongoLena indlela evamile yokuqoqa i-zooplankton nezilwane ezihlobene nayo. Ngemuva kokuhlonzwa kwayo, yathunyelwa ku- I-National Museum of Natural History of Chile ukuze kulondolozwe futhi kuboniswane nomphakathi wocwaningo.
Ithimba lobuchwepheshe ligcizelela ukuthi ukuba nezinto ezitholakalayo ku izigaba zakuqala Lokhu kusiza ukuhlonza i-taxonomic, njengoba izinguquko ze-morphological ngesikhathi sokuthuthukiswa kwezinhlanzi ezinamathambo zingabaluleka. Leli rekhodi elisha lizosiza ukulungisa okhiye bokuxilonga futhi izinkomba zokuqhathanisa ngezifundo zesikhathi esizayo.
Umqondisi we-Marine Programme ohilelekile, Mathias Hüne, igcizelele ukuthi irekhodi lezibungu le-Champsocephalus esox lifaka isandla esikhulu elwazini lokuhlukahluka kwe-BahÃa Inútil futhi lisekela ukuqapha izitayela zemvelo endaweni.
Obani ababambe iqhaza kanye nohlaka locwaningo
Lo mkhankaso wethulwe ngabakwa Ukuvuselela kabusha Uhlelo Lwasolwandle lwaseChile, ngokubamba iqhaza kwe I-Universidad de Magallanes futhi i I-ValparaÃso UniversityUmgomo wawuwukwakha a izici eziphelele yohlelo: ukusuka e-zooplankton kanye nasemiphakathini ejulile yolwandle kuya ezinhlanganweni ezixhumene ne-substrate.
Isethi yamasu yayihlanganisa nethi ye-bongo eshiwo ngenhla, amakhamera amarobhothi angaphansi kwamanzi y ama-dredgesLokhu kuvumele ukuqoqwa kwedatha eqhathanisekayo ekubunjweni, i-biomass, nokusabalalisa. Le ndlela yezinhloso eziningi isiza ukuhlonza amaphethini emvelo kanye nezingcindezi zomuntu ezingase zibe khona.
Inhlanzi ejwayele ukubanda kakhulu
Okubizwa ngokuthi I-icefish Adume ngokujwayela kwawo amanzi aneqhwa, afana nalawa amanye izinhlanzi zamanzi abandayo. Ezinye izinhlobo, njenge I-Chaenocephalus aceratus, okwamanje umzimba okhanyayo, ukungabi khona kwezikali kanye igazi elingenambala, ekwazi ukuthutha umoya-mpilo ngaphandle kwe-hemoglobin.
Of Izinhlobo ezingama-16 ezaziwayo Kuleli qembu, i-Champsocephalus esox iyona kuphela esakazwayo ngaphesheya kwe-AntarcticaAbantu babo bahlala eStrait of Magellan, eTierra del Fuego, eBeagle Channel, naseFalkland/Malvinas Islands, lapho abantu baseYaghan beyazi ngokuthi. "tsataki".
I-Biodiversity of Useless Bay: idatha ebingakalinganiswa
Lolu hambo luhlanganise i-X-ray engakaze ibonwe ngaphambili ama-benthic ahlanganisiwe kusuka endaweni. Bakhonjwa izinhlobo ezingaphezu kwama-100 zezilwane ezingenamgogodla okunzima ukuzibona ngeso lenyama futhi cishe Izigaba ze-150 zezinto eziphilayo ze-sediment, ikakhulukazi ama-polychaetes, ukhiye we- ukugaywa kabusha kwezinto eziphilayo namaketanga okudla. Lokhu okutholakele kuhlobana nomsebenzi we amakamelo anikezelwe izilwane ezingenamgogodla ezikhungweni zesayensi.
Imiphakathi ehlobene ne izindawo zokuhlala ezijulile ngokuhlukahluka okuphezulu kanye ne-biomass. Ngokusho kwesifundiswa I-Américo Montiel (UMAG), i-BahÃa Inútil ibiphakathi kwemikhakha enolwazi oluyindlala, futhi manje inemininingwane mayelana ingcebo ethileukusatshalaliswa kanye ne-biomass.
Kwenziwa imisebenzi yokumba endaweni inkalankala yesicabucabu, izimbaza nama-sea urchinsNgakho-ke, ukuba nochungechunge lwereferensi olwandle kuzosiza ukuphatha ukusetshenziswa ngendlela enolwazi kanye nokulinganisa amandla imithelela yendawo.
Izinsongo kanye nesidingo sokuvikelwa
I-ecosystem ibhekana nezingcindezi ezifana nalezi ukudoba ngokweqile, the ama-micro-dumps futhi i ukufudumala kolwandlengaphezu kwamaphrojekthi ezimboni angaba khona. Ngo-2023, iForum for the Conservation of the Patagonian Sea yahlonza le ndawo njengenye ye-macro-ecosystems izinga eliphansi lokuvikela esifundeni
Ku-Champsocephalus esox, ukuthambekela kuyakhathaza: izilinganiso zenkambu kanye nezifundo zikhomba ekwehleni kwendawo yonke. 30% ezizukulwaneni ezintathu. Ngakho-ke, i- IUCN Ifakwe esigabeni sezinhlobo zezilwane ngo-2019. engoziniLokhu kuqinisa ukuphuthuma kwezinyathelo zokuphatha nokuvikela.
Ngomlando wokuqala wezibungu oseqoshwe phansi kanye nesizinda esicebile semvelo, indawo yase-BahÃa Inútil ithola indawo qinisa ukongiwa kwayo, thuthukisa ukubhekwa futhi uqondise izinqumo zomphakathi ngokusekelwa kwesayensi, into umphakathi wocwaningo oyayazisa futhi edingwa ukuphathwa kwendawo.
