Abantu abahlamba umzimba kwiilwandle zaseCantabria baye baxakwa kukufika ngokukhawuleza kweesalps, gelatinous marine organisms, e-El Sardinero, Mataleñas, San Juan de la Canal naseLa Maruca.
Kule nqaku siza kukuxelela Ziziphi iisalps kwaye kutheni zininzi ngoku kwiilwandle zaseCantabria?.
Yintoni i-salps
Ngoxa ubukho bazo busenokubangela inkxalabo ekuqaleni, kubalulekile ukuphawula ukuba ezi zidalwa azinabungozi kwaphela yaye aziyongozi ebantwini. Kufuneka kwakhona kuqatshelwe ukuba kwiveki nje edlulileyo kwabonwa iinqanawa zemfazwe zasePortugal kwiilwandle zaseLaredo, Santoña, Noja naseSan Vicente. Kuyaqondakala ukuba oku kubangele i-alamu phakathi kwabahlambi, kodwa Kuyimfuneko ukucacisa ukuba ukubonakala kwe-salps kuhluke kwaye kuncinci kakhulu.
Iisalps zizidalwa zaselwandle ezingaqhelekanga ezidelelayo ukwahlulwa njengentlanzi okanye ijellyfish. Izinto eziphilayo zaselwandle ezinenkangeleko ecacileyo zihlala zibhidaniswa ne-microplastics okanye amaqhekeza eglasi. Ezi zilwanyana zingenamqolo zingenabungozi, ezaziwa ngokuba ziisalps, zidlala indima ebalulekileyo kwi-ecosystem yolwandle. Iingcali ziqinisekisa ukuba ukwanda kwe-salp kunxweme lwaseCantabrian kubangelwa ngokuthe ngqo kokutshintsha kwemozulu kunye nokunyuka kwamaqondo okushisa.
Nangona ifana ne-jellyfish, i-Salpa fusiformis ayiyona intlanzi okanye i-jellyfish. Bakwiqela lezilwanyana ezibizwa ngokuba ziitunicates, yaye igama labo lezenzululwazi nguSalpa fusiformis. Ezi zidalwa ziihermaphrodites, nto leyo ethetha ukuba banamalungu okuzala amadoda nabasetyhini. Inkqubo yabo yokuzala ibandakanya ukutshintshiselana ngokuzala, apho badlula kuzo zombini izigaba ze-asexual kunye nezesondo. Ngexesha le-asexual phase ziyazalana nge-cloning, ngelixa kwisigaba sesondo zisebenzisa i-gametes yabasetyhini kunye namadoda. Uphawu oluphawulekayo lweSalpa fusiformis kukuphindaphinda komthamo okhawulezayo.
Ezi zilwanyana ezingenamqolo zidla ngokuzibonakalisa ngeendlela ezimbini ezahlukeneyo: ngabanye okanye ngokulandelelanayo, ukwandisa ukuya kwi-15 yeemitha.
Kufuneka wenze ntoni xa udibana nezi zidalwa?
Bobabini amagunya asekuhlaleni kunye neengcali zaselwandle zigxininisa ukuba ukubonakala kwe-salps kuyinto yendalo kunye nesiganeko esidlulayo esingabonisi ingozi kukhuseleko lwamalwandle okanye impilo-ntle yabadadi. Kuyacetyiswa ukuba ungawahoyi kwaye uqhubeke njengesiqhelo. Ngokungafaniyo ne-jellyfish, i-salps ayinazo iintente kwaye ngoko ayihlabanga okanye ibangele nawuphi na umonakalo xa idibana nolusu.
Ifumaneka kwiilwandle kwihlabathi jikelele, ngakumbi i-fusiform salp okanye isalp eqhelekileyo, iisalps zidlala indima ebalulekileyo ekugcineni ulungelelwaniso lwendalo yolwandle. Ezi zinto ziphilayo zingaqhelekanga zihluza amanzi olwandle, zilawula ngokufanelekileyo i-phytoplankton kunye nomjikelo wekhabhoni. Nje ngeziphumo, Ubukho bayo buluncedo kakhulu, njengoko buqinisekisa ulungelelwaniso kunye nenkqubela phambili ye-ecosystem yaselwandle.
Ubukho bezi zilwanyana zingenamqolo ngaselunxwemeni busenokubothusa okanye boyike abo bangazaziyo. Nangona kunjalo, akukho mfuneko yokuba wothuke. Enyanisweni, abantu abahamba elwandle baye baqinisekiswa ukuba iisalps aziyongozi. Ukongezelela, ubukho bayo busebenza njengesikhumbuzo semiphumo yokufudumala kwehlabathi kwi-ecosystem yethu, ebangele utshintsho ekusasazweni kweentlobo ezahlukeneyo zaselwandle.
Ngaphandle kobukho bezi zinto ziphilayo, unxweme lwaseCantabria lusaqhubeka luyindawo ekhuselekileyo neyonwabisayo, ngakumbi ngexesha lehlobo. Abasemagunyeni baya kuqhubeka nokubeka iliso kwimeko kwaye banike ulwazi oluyimfuneko ukuze kuqinisekiswe uxolo lwabahlali kunye neendwendwe eziya kwindawo.
Iimpawu ezahlukileyo
Iisalps zikhona ngeendlela ezahlukeneyo, nokuba ziikoloni ezenziwe ngamakhulu abantu okanye njengezinto eziphilayo ezizimeleyo okanye amatyathanga. La matyathanga anamandla okufikelela kubude obunomtsalane obufikelela kwi-15 leemitha, eqhutywa ngamandla emisinga yolwandle. Iisalps ubukhulu becala zenziwe ngamanzi, ezimele i-95% yokwakheka kwazo, okubenza babuthathaka kakhulu kwaye bangakwazi ukuphila ixesha elide ngaphandle kwendawo abahlala kuyo emanzini.
Iisalps, ngokungafaniyo nejellyfish, azikwazi ukuhlaba okanye zibangele ingozi. Indima yabo ngaphakathi kwe-ecosystem ibaluleke kakhulu, kuba ibalulekile kwinkqubo yokuhlanjululwa komoya kunye nokufunxa i-carbon dioxide (CO2) emanzini, ngaloo ndlela igalelo elibalulekileyo ekulweni nokutshintsha kwemozulu.
Ixabiso lokusingqongileyo kweesalips
Iisalps zibalulekile ekugcineni iintlobo ngeentlobo zezinto eziphilayo zaselwandle. Ngokusebenzisa kwabo iphytoplankton, bakhuthaza ngokukhutheleyo ukuthinjwa kweCO2 emazantsi olwandle, benegalelo elikhulu ekuthotyweni kwale gesi yegreenhouse emoyeni.
Ngaphezu koko, emva kokunyamalala kwazo, ezi zidalwa zitshona enzulwini. ukuba sisixhaso kuluhlu olubanzi lwezinto eziphilayo zaselwandle, njengee-cetaceans kunye nofudo. Izikhokelo zabaqubha xa bedibana nesalps.
Ukuqinisekisa inhlalakahle ye-salps, kubalulekile ukuyeka ukubaphatha okanye ukuwasusa emanzini, njengoko banokutshabalala xa besuswa kwindawo yabo yokuhlala yendalo nangona bengabonisi nayiphi na isongelo.
Ukugcina ulwakhiwo lwabo oluthambileyo, kucetyiswa ukuba ugweme ukuphatha, nokuba ngaba abenzi umonakalo. Xa abahlanguli bebona amaqela amakhulu esalps, Kubalulekile ukubazisa ukuze bakwazi ukuphumeza izenzo eziyimfuneko kunye nokukhokela abanye abadadi.
Ukukhuthaza ukukhuselwa kunye nokugcinwa kweesalps kwi-ecosystem kuququzelelwa ukuqonda okubanzi kwexabiso lazo lwe-ecological kunye nokubaluleka kwazo malunga nokuqonda ngokusingqongileyo.
Indlela yokwahlula kwi-jellyfish
Iisalps zine-tubular kunye nomzimba ocacileyo ngokupheleleyo, ovumela ukuba bazifihle emanzini. Ngokungafaniyo nejellyfish, iisalps zihamba ngokufinyela, zimpompa amanzi emzimbeni ukuze zihambe. Esi senzo sokumpompa sikwavumela ukuba bahluze amasuntswana okutya emanzini, afana ne-phytoplankton. Iisalps zidla ngokufumaneka kumatyathanga amakhulu okanye kwiikholoni ezidada phezu komphezulu wolwandle, enye yeempawu zazo ezahlukileyo. Ngaphandle koko, I-salps ayinayo i-tentacles, eyahlula ngokucacileyo kwi-jellyfish.
I-Jellyfish, kwelinye icala, i-cnidarians, iqela elihluke ngokupheleleyo lezilwanyana zaselwandle. Eyona milo ixhaphakileyo yileyo "yomnqwazi" okanye intsimbi eneentente ezijingayo ezantsi. Iintente zejellyfish zigqunywe ziiseli ezihlabayo, ezibizwa ngokuba zii<em>cnidocyte, ezizisebenzisayo ukuze zibambe amaxhoba nokuzikhusela. Ngokungafaniyo ne-salps, i-jellyfish ayenzi amatyathanga adadayo. Intshukumo yabo inesingqisho ngakumbi kwaye i-undulating, ngenxa yokuncipha kwentsimbi yabo, evumela ukuba bahambe ngokuzimeleyo emanzini.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nokuba yintoni i-salps kwaye kutheni kukho ezininzi zazo kwiilwandle zaseCantabria ngoku.
