Ukutholakala kwe-a Izinhlobo ezintsha ze-moon jellyfish eGulf of Mexico Lokhu kutholakala kuphinde kwagqamisa ukuhlukahluka okukhulu kwezinto eziphilayo zalesi sifunda sasolwandle. Ithimba labacwaningi abavela eTexas A&M University-Galveston lichaze ngokusemthethweni lesi sidalwa, esingowohlobo lwe-Aurelia oludumile, ngemuva kweminyaka eminingana yokusebenza ensimini kanye nokuhlaziywa kwelebhu.
Ngalesi sihlonzi, ikhathalogi ye-moon jellyfish eGulf of Mexico Inani lezinhlobo eziqashelwayo likhuphuke lisuka kwezintathu laya kwezine, okuwukukhuphuka okuncane kodwa okuwukuthuthuka okukhulu kwesayensi yezinto eziphilayo zasolwandle. Lolu hlobo lokuthola izinto ezintsha lusiza ekucaciseni ukuqonda kwethu ukuthi izimiso zemvelo zasolwandle zihlelwe kanjani kanye nendima edlalwa yizinhlobo ngazinye.
Ilungu elisha lohlobo lwe-Aurelia
Uhlobo olusha, okubhekiselwa kulo ezincwadini zesayensi ngokuthi I-Aurelia EjulileIngeqembu le-jellyfish eyaziwa ngokubukeka kwayo okuhlukile. I-Moon jellyfish yohlobo lwe-Aurelia inomzimba oyisicaba, okhanyayo, onesimo esifana nediski ethambile, ethambile, efana nobuso benyanga uma ibukwa ngaphansi emanzini.
Esinye sezici ezibonakala kakhulu ezihlukanisa lawa ma-jellyfish yi- ukuma kweqabunga le-clover lezitho zabo zokuzalaLawa ma-jellyfish ahlukaniswa ngezakhiwo zawo ezine ezihlelwe cishe ngokulinganayo, ezibonakala ngensimbi esobala. Lesi sici sivumela ochwepheshe ukuthi bahlukanise kalula i-moon jellyfish kwezinye izinhlobo ze-jellyfish ezivame kakhulu ogwini lwaseYurophu naseMelika.
Ithimba laseTexas A&M-Galveston lihlanganise ukubonwa kwesimo somzimba namathuluzi ofuzo lwama-molecule ukuqinisekisa ukuthi lolu uhlobo oluhlukile kwezinye izinhlobo ze-Aurelia ezichazwe ngaphambilini. Le ndlela exubile isivame eminyakeni yamuva nje, njengoba Umehluko phakathi kwezinhlobo ze-jellyfish ungaba mfushane kakhulu. ekuqaleni futhi azibonakali ngaso sonke isikhathi ngaphandle kokuhlaziywa kwe-DNA.
Ngokusho komcwaningi webhayoloji yasolwandle uMaria Pia Miglietta, uprofesa ohlangene ohilelekile kulolu cwaningo, inqubo yokuhlonza igcizelele ukuthi Kusenokwehlukahlukana okuningi okusazobhalwa phansi eGulf of MexicoUchwepheshe uveza ukuthi lokhu okutholiwe kungaba okunye nje kweziningana ezizomenyezelwa njengoba amaphrojekthi okuthatha amasampula kanye nokulandelana kwezakhi zofuzo endaweni eqhubeka.
I-Jellyfish engeyona ingozi kakhulu kubantu
Ngaphandle kwesithakazelo sabo kwezesayensi, i-moon jellyfish yohlobo lwe-Aurelia inezici ezithile eziyenza yaziwe kakhulu: ingozi ephansi kubantuNgokungafani nezinye izinhlobo ze-jellyfish, njenge- i-man-of-war jellyfishNakuba amangqamuzana ka-Aurelia ahlabayo angaba buhlungu noma abe yingozi, awavamile ukungena kalula esikhumbeni somuntu.
Lokhu kusho ukuthi ukuxhumana ngezikhathi ezithile ne-moon jellyfish kuvame ukuba hhayi ukubangela ukusabela okungathi sÃnaLokhu kuzenza zibe yizinto eziphilayo ezivamile ezindaweni zokudoba zasemanzini zomphakathi eYurophu nasemhlabeni jikelele. Ukubukeka kwazo okumangalisayo, kuhlangene nokungabi nangozi kwazo, kuzenza zaziwe kakhulu ezindaweni zemfundo yasolwandle nasezikhungweni zocwaningo.
Endabeni ethile ye-Aurelia profunda, abacwaningi baveza ukuthi ukuziphatha kwayo kanye nezici zayo zokuhlaba kufana nokwezinye izinhlobo ezihlobene. Ngakho-ke, umqondo wokuthi leli lungu elisha lohlobo... liyagcinwa. Akubeki ingozi enkulu kubabhukudi noma ababhukudi., into ebaluleke kakhulu ezindaweni zezivakashi zaseGulf of Mexico nasemanzini aseduze.
Kumphakathi wesayensi waseYurophu, lolu lwazi luwusizo uma uqhathanisa inani lezinhlanzi ze-moon jellyfish empumalanga ye-Atlantic naseMedithera nalezo eziqoshwe ngaphesheya kolwandle. Uhlobo ngalunye olusha oluchazwe lusiza ekwenzeni ukwakha kabusha umlando wokuziphendukela kwemvelo kanye nemizila yokuhlakazeka yalezi zinto eziphilayo, ezincike kakhulu emifudlaneni yolwandle.
Imiphumela yokuhlukahluka kwezinhlobo ze-Gulf of Mexico
Ukutholakala kwe-Aurelia profunda kuqinisa umbono wokuthi iGulf of Mexico iyi- indawo ethandwa kakhulu ngezinhlobo ezahlukene zezilwane zasolwandleLesi sigodi, esabelwana ngamazwe amaningana futhi esixhunywe ne-Atlantic, siyikhaya lezindawo zokuhlala ezahlukahlukene, kusukela emanzini angajulile asogwini kuya ezindaweni ezijulile, ezingakafundwa kahle.
Njengoba kunezinhlobo ezintsha, manje sekukhona i-moon jellyfish ezine eziqashelwe endaweni, okubonisa ukuthi, ngisho nangaphakathi kweqembu elifanayo lezinto eziphilayo ezaziwayo, Izinhlobo ezazinganakwa ngaphambili ziyaqhubeka nokuvela.Lesi simo asiyona into eyenzeka eGulf kuphela: kwezinye izindawo eziningi, okuhlanganisa neYurophu, kusolwa ukuthi kusenezinhlobo ezingaqondakali ezingachazwanga, ezingahlukaniswa ngokunembile kuphela ngokuhlaziywa kwezakhi zofuzo.
UProfesa Miglietta nethimba lakhe bagcizelela ukuthi lolu hlobo lokuthola lutho luvula ithuba lemibuzo emisha yesayensi. Isibonelo, baphenya ukuthi izinhlobo ezahlukene ze-Aurelia zisakazwa kanjani ngaphakathi kweGulf, ukuthi zidlala yiphi indima kuma-food webs, nokuthi zingase zithinteke kanjani yizici ezifana... ukushintsha kwesimo sezulu, ukungcola, noma ukudoba ngokweqile yezinye izinhlobo zasolwandle.
Kubacwaningi baseYurophu abasebenza ngezinhlobo ezahlukene zezilwane zasolwandle, indaba ka-Aurelia profunda iyisikhumbuzo sokuthi Ukuntuleka kwamarekhodi akusho ukuthi azikho izinhloboEmanzini ase-Atlantic azungeze i-Iberian Peninsula kanye naseMedithera, lapho kubonwa khona i-moon jellyfish, umzamo ofanayo wokuhlola amasampula kanye nokuhlaziya izakhi zofuzo cishe uzokwembula ukwehlukahluka okukhulu kunalokho okungabonakala ngamehlo enyama.
Ukuhambisana kweSpain neYurophu
Nakuba lokhu kutholakala kwenziwe eGulf of Mexico, imiphumela yako idlulela ngale kwemingcele yesifunda futhi kuyathakazelisa naseSpain kanye nalo lonke elaseYurophu. I-Jellyfish yohlobo lwe-Aurelia itholakala e- izindawo eziningi ezisogwini lwaseYurophu, kuhlanganise nezaseSpain, kokubili e-Atlantic naseMedithera, ngakho-ke ukwazi izihlobo zabo zaseMelika kangcono kungasisiza siqonde abantu bendawo.
Ososayensi baveza ukuthi izinhlobo eziningi ze-jellyfish zine- imijikelezo yokuphila eyinkimbinkimbi kanye nezigaba ezincane kakhulu Lezi zinhlobo zivame ukunganakwa, okwenza kube nzima ukuzibona ngokusekelwe kuphela ekubonweni okuhlukile emabhishi noma emachwebeni. Incazelo yezinhlobo ezintsha kwezinye izingxenye zomhlaba ikhuthaza ukwanda komsebenzi wasensimini eYurophu ukuze kunqunywe ukuthi ngabe imiphakathi yezinhlobo ezahlukene iqoqwa ngaphansi kwegama elifanayo.
Esimweni saseYurophu, lapho kugxilwa khona kakhulu emthonjeni wezimbali ze-jellyfish kwezokuvakasha kanye nokudoba, kube nokuhlukaniswa okufanele kwezinhlobo ze-jellyfish. Izinhlobo zasolwandle Kuyisihluthulelo. Nakuba i-moon jellyfish efana ne-Aurelia profunda Azivamisile ukubangela izinkinga ezinkulu kubantu abagezayoUkwazi kahle ukuthi yiziphi izinhlobo ezivela endaweni ngayinye kubalulekile ekuhleleni amasu okuqapha nokuphatha.
Ngaphezu kwalokho, ukuqhathanisa abantu abavela eGulf of Mexico nasempumalanga ye-Atlantic kunganikeza izinkomba mayelana ukuxhumana komlando phakathi kwezizinda zolwandlekanye nokwethulwa okungahlosiwe okungaba khona ngokusebenzisa ukuhamba olwandle. Lolu hlobo lokuhlaziya lubaluleke kakhulu kwi-European Union, enemithethonqubo ethile mayelana nezinhlobo ezihlaselayo kanye nokulondolozwa kwezinhlobonhlobo zezinto eziphilayo zasolwandle.
Ulwandle olusagcwele izinto ezingaziwa
Indaba ye-jellyfish entsha yenyanga eGulf of Mexico ibonisa izinga ulwandle oluqhubeka lukhona ngalo. izindawo ezingahlolwanga kahleNaphezu kwentuthuko kwezobuchwepheshe kwezokudoba kwezilwandle, iningi lezingxenye zamanzi ezingaphansi kolwandle kanye nezingqimba eziningi zamanzi aphakathi ziyaqhubeka nokuthola ukuvakashelwa kwesayensi ngezikhathi ezithile.
Ithimba le-Texas A&M-Galveston likhomba ukuthi Lokhu okutholakele kungaba yinto yokuqala nje ochungechungeni lwezinto ezitholakele. okuhlobene ne-jellyfish kanye nezinye izilwane ezingenamgogodla ezihlala endaweni. Umkhankaso ngamunye wokuthatha amasampula unikeza idatha entsha futhi, ngokuvamile, amasampula adinga ukubuyekezwa ekuhlukanisweni nasezincazelweni zangaphambilini.
Okwamanje, ochwepheshe baseYurophu bagcizelela isidingo sokugcina nokwandisa izinhlelo zocwaningo lwasolwandle e-Atlantic naseMedithera. Okuhlangenwe nakho eGulf of Mexico kubonisa ukuthi lapho ukusampula okuhleliwe kuhlanganiswa namathuluzi ezakhi zofuzo zesimanje, isithombe sezinhlobonhlobo zezinto eziphilayo sithuthuka kakhulu. Kungashintsha ngokuphawulekayo eminyakeni embalwa nje.
Ngamafuphi, ukuqashelwa kwe-Aurelia profunda njengohlobo olusha lwe-moon jellyfish akugcini nje ngokwandisa inani lezinhlobo ezaziwayo eGulf of Mexico, kodwa futhi Kuqokomisa ukubaluleka kokuqhubeka nokucwaninga nokuvikela izimiso zemvelo zasolwandle.Umsebenzi wamaqembu omhlaba wonke, ngokubambisana okungase kuhilele izikhungo eSpain nakwamanye amazwe aseYurophu, uzoba yisihluthulelo sokwembula izinto eziningi ezingaziwa ezisekhona olwandle.
