Ososayensi bathole ukuthi uLwandle i-Alboran, ekugcineni osentshonalanga yeMedithera, lubhekana noshintsho oluphawulekayo lwemvelo., eqhutshwa ngokuyinhloko yi- ukufudumala kwezweLo mkhuba ubonakala ngokufika kwezinhlobo ezintsha zezilwane de peces ezindaweni ezishisayo, okuphawula ushintsho ezinhlobonhlobo zezinto eziphilayo zasolwandle endaweni.
Ubukhona de peces akukaze kubhalwe ngaphambili emanzini aseningizimu yeSpain Lokhu kumangaze ochwepheshe nabadobi bendawo. Imiphumela yocwaningo lwakamuva ibonisa ukuthi ukwakheka kwezinhlobo zezilwane kushintsha ngokushesha, ikakhulukazi endaweni ephakathi kweStrait of Gibraltar kanye noLwandle lwase-Alboran ngokwalo. Lo mkhuba, manje owaziwa ngokuthi "i-tropicalization," iwukubonakaliswa okubambekayo kokuthi ukunyuka kwamazinga okushisa kwamanzi kuyishintsha kanjani ibhalansi yemvelo yalezi zimiso zemvelo.
Izinguquko ezinhlobonhlobo zezinto eziphilayo: izinhlobo ezintsha kanye nolwandle olufudumele
Ekuhlaziyeni kwakamuva kwesayensi, kurekhodiwe izibonelo ezintsha ezingama-25. de peces eMedithera yaseSpain, okungama-23 kuwo ayengenawo umlando wangaphambili endaweni. Okugqame kakhulu Akuyona nje inombolo, kodwa okuthandwayo okushisayo kwalezi zinhlobo: Izengezo ezintsha zikhetha amanzi afudumele, ngesilinganiso sokushisa esingaphezu kuka-6 degrees ngaphezu kwezinhlobo ezivamile. Lokhu kuveza ukuthi ukuguquguquka kwesimo sezulu emhlabeni kuyithinta kanjani imvelo ehlukahlukene, ikakhulukazi ezindaweni ezifana nolwandle i-Alboran..
UJosé Carlos Báez, umcwaningi e-Spanish Institute of Oceanography kanye nombhali ngokubambisana wocwaningo, ugqamisa lokho I-Alboran Sea kanye nesifunda sase-Strait of Gibraltar zibhekene nomthelela omubi kakhulu., uma kuqhathaniswa nezinye izindawo ezifana nokuklanywa kwe-Levantine-Balearic. Lapha ubufakazi busobala: ukusatshalaliswa okungalingani kwemiphumela yokufudumala kwasolwandle kukhombisa ukuthi eminye imikhakha isengozini kangakanani kuneminye.
Phakathi kwezinto ezivumela i-tropicalization kunjalo ukwanda okuqhubekayo kwezinga lokushisa lamanzi, ukungena kwezinhlobo zezilwane ngokusebenzisa ukuxhumana kwe-Atlantic y ukudluliswa ngokuzenzakalelayo de peces kanye ne-algae evela kwezinye izifunda, ngaphezu kwalokho ukucindezela komuntu okukhulu, lisuselwa ku- Ithrafikhi yasolwandle kanye nezokuvakasha ogwini lwase-Andalusian. Le ndawo ivuna ukuthi izinhlobo ezingavamile zithola indawo yokuhlala efanelekayo ukuze zithuthuke oLwandle i-Alboran.
Kutholwe imithelela yemvelo kanye nezinhlobo zezimpawu
Akuzona kuphela izinhlobo eziningi ezifikayo, kodwa ezinye zibonisa izici eziphawulekayo.. Izibonelo ezifana ne-lionfish (Pterois miles), owaziwa ngokudlulela kwezinye izilwandle, noma ushaka womkhomo (I-Rhincodon typus), ngokuvamile zitholwa ngezikhathi ezithile futhi zingahlotshaniswa nezenzakalo zemvelo kanye nesenzo somuntu kanye nezinga lokushisa elikhuphukayo.
Kufika ku-36% wokubonwa okusha kuhlotshaniswa ngqo nenqubo ye-tropicalization., kuhlanganise nezinhlobo ezifana I-Cephalopholis taeniops, Amalobhothi aseSurinamese y I-Paranthias furcifer. Ngaphezu kwalokho, ingxenye yamarekhodi ihambisana izinhlobo eziyimfihlo, okufana kwazo nezinye izinhlobo zezilwane zasendaweni ngaphambili kwakwenze kwaba nzima ukuhlonza.
ukufuduka de peces izinhlobo zemvelo zalezi zinhlobo ezintsha zingaba nemiphumela edabukisayo cishe ubudlelwano bokudla kanye nokuzinza kwe-ecosystem, kuxwayisa umcwaningi uDavinia Torreblanca. Ukwethulwa okukhulu kwe-algae njenge I-Rugulopteryx okamurae kanye nokunye ukuphazamiseka kwemvelo zibhebhethekise izinselelo ezibhekene ne-Alboran Sea.
Izincomo kanye nekusasa lokuphathwa kwasolwandle
Ochwepheshe bagcizelela isidingo sokuqhubeka nokuqapha ukuvela kwezinto eziphilayo zasolwandle. oLwandle i-Alboran nakwezinye izindawo zaseMedithera. Izincomo ezifana ukuhlanganisa okuguquguqukayo kwemvelo kanye nezici zomuntu (ezifana nezokuvakasha, ukudoba kakhulu kanye nokuthuthwa kwezimoto zasolwandle) ezinhlelweni zokuqapha kubalulekile ukulindela nokunciphisa imithelela emibi engaba khona.
Ukulondolozwa kwalezi zimiso zemvelo kudinga ukwamukela izinqubomgomo eziguquguqukayo neziguquguqukayo., ekwazi ukuphendula ku ukushintshashintsha okusheshayo okubangelwa ukushintsha kwesimo sezulu. Ukwazi lezi zinqubo ngokugcwele kubalulekile vikela ingcebo yemvelo kanye nezithakazelo zemiphakathi yasogwini.
Ulwandle lwase-Alboran seluphenduke ilabhorethri yemvelo lapho ukufudumala nokufika kwezinhlobo ezishisayo kusebenza njengezinkomba zoshintsho emhlabeni.Ukuqapha, isayensi, kanye nezimpendulo eziguquguqukayo kuzoba ukhiye ekugcineni ibhalansi yemvelo esikhathini esizayo esiseduze.
