Ababhukuda emabhishi aseCantabria badidwe ukufika kungazelelwe kwama-salps, izinto eziphilayo zasolwandle ezine-gelatinous, e-El Sardinero, Mataleñas, San Juan de la Canal naseLa Maruca.
Kulesi sihloko sizokutshela Ayini ama-salps futhi kungani eningi kangaka manje emabhishi aseCantabria?.
Ayini ama-salps
Nakuba ukuba khona kwazo kungase kubangele ukukhathazeka ekuqaleni, kubalulekile ukuqaphela ukuthi lezi zilwane azinangozi ngokuphelele futhi azilona usongo kubantu. Kufanele futhi kuqashelwe ukuthi ngesonto eledlule kwabonwa imikhumbi yempi yamaPutukezi emabhishi aseLaredo, Santoña, Noja naseSan Vicente. Kuyaqondakala ukuthi lokhu kubangele i-alamu phakathi kwabageza, kodwa Kudingekile ukucacisa ukuthi ukubukeka kwe-salps kuhlukile futhi kuncane kakhulu okwethusayo.
I-salps iyisilwane sasolwandle esingavamile esingahambisani nokuhlukaniswa njengezinhlanzi noma i-jellyfish. Izilwane zasolwandle ezinokubukeka okusobala ngokuvamile zingadideka nama-microplastic noma izingcezu zengilazi. Lezi zilwane ezingenamgogodla ezingenabungozi, ezaziwa ngokuthi ama-salps, zidlala indima ebalulekile esimisweni sezinto eziphilayo zasolwandle. Ochwepheshe bayaqinisekisa ukuthi ukwanda kwenani le-salp ogwini lwaseCantabrian kuwumphumela oqondile wokushintsha kwesimo sezulu kanye nokukhuphuka kwamazinga okushisa.
Naphezu kokufana kwayo ne-jellyfish, i-Salpa fusiformis empeleni ayiyona inhlanzi noma i-jellyfish. Bangamalungu eqembu lezilwane okuthiwa ama-tunicates, futhi igama labo lesayensi i-Salpa fusiformis. Lezi zidalwa zingama-hermaphrodites, okusho ukuthi banazo zombili izitho zokuzala zabesilisa nabesifazane. Inqubo yabo yokuzala ibandakanya ukushintshashintsha kwezizukulwane, lapho bedlula kuzo zombili izigaba ze-asexual nezocansi. Ngesikhathi se-asexual phase zizalana ngokuhlanganisa, kuyilapho esigabeni socansi zisebenzisa ama-gametes abesifazane nabesilisa. Isici esiphawulekayo seSalpa fusiformis amandla ayo okuphindaphinda ngokushesha.
Lezi zilwane ezingenamgogodla zivame ukuzibonakalisa ngezindlela ezimbili ezahlukene: ngamunye noma ngokulandelana, afinyelela kumamitha ayi-15.
Yini okufanele uyenze lapho uhlangana nalezi zidalwa?
Kokubili iziphathimandla zendawo kanye nochwepheshe basolwandle bagcizelela ukuthi ukubonakala kwama-salps kuyisenzakalo esingokwemvelo futhi esidlulayo esingameleli usongo ekuphepheni kwamabhishi noma inhlalakahle yababhukudi. Kuyancomeka ukuthi umane ungazinaki bese uqhubeka njengokujwayelekile. Ngokungafani ne-jellyfish, ama-salps awanawo amathente futhi ngenxa yalokho awalumeli noma abangele noma yimuphi umonakalo lapho ehlangana nesikhumba.
Itholakala olwandle emhlabeni jikelele, ikakhulukazi i-fusiform salp noma i-salp evamile, ama-salps adlala indima ebalulekile ekugcineni ibhalansi yemvelo yasolwandle. Lezi zinambuzane ezingavamile zihlunga amanzi olwandle ngenkuthalo, zilawula ngempumelelo i-phytoplankton nomjikelezo wekhabhoni. Ngenxa yalokho, Ukuba khona kwayo kunenzuzo kakhulu, njengoba kuqinisekisa i-ecosystem yasolwandle elinganiselayo futhi ephumelelayo.
Ukuba khona kwalezi zilwane ezingenamgogodla ngasogwini kungase kumangaze noma kukhathaze labo abangazazi. Nokho, asikho isidingo sokwethuka. Eqinisweni, abasolwandle baye baqinisekiswa ukuthi ama-salps awalona usongo. Ukwengeza, ubukhona bayo busebenza njengesikhumbuzo semiphumela yokufudumala kwembulunga yonke esimisweni sethu sezinto eziphilayo, okubangele izinguquko ekusatshalalisweni kwezinhlobo ezihlukahlukene zasolwandle.
Naphezu kokuba khona kwalezi zinambuzane, ugu lwaseCantabria lusaqhubeka luyindawo ephephile nejabulisayo, ikakhulukazi phakathi nenkathi yasehlobo. Iziphathimandla zizoqhubeka nokuqapha isimo futhi zinikeze ulwazi oludingekayo ukuze kuqinisekiswe ukuthula kwabahlali nabavakashi endaweni.
Izici ezihlukile
Ama-salps akhona ngezindlela ezahlukahlukene, njengamakoloni akhiwe ngamakhulu abantu noma izinto eziphila zodwa noma amaketango. Lamaketango anamandla okufinyelela ubude obumangalisayo obufika kumamitha ayi-15, eqhutshwa amandla emisinga yolwandle. Ama-salps akhiwe kakhulu ngamanzi, amelela u-95% wokwakheka kwawo, okubenza bantekenteke ngokwedlulele futhi bangakwazi ukuphila isikhathi eside ngaphandle kwendawo ehlala emanzini.
Ama-salps, ngokungafani ne-jellyfish, awanawo amandla okuhlaba noma okulimaza. Indima yabo ngaphakathi kwe-ecosystem ibaluleke kakhulu, njengoba ibalulekile ohlelweni lokuhlanza umoya kanye nokumuncwa kwe-carbon dioxide (CO2) emanzini, ngaleyo ndlela ibe negalelo elikhulu ekulweni nokushintsha kwesimo sezulu.
Inani lemvelo lama-salps
Ama-salps abalulekile ekugcineni izinhlobonhlobo zezilwane zasolwandle. Ngokusebenzisa kwabo i-phytoplankton, bakhuthaza ngenkuthalo ukuthathwa kwe-CO2 phansi olwandle, okunomthelela omkhulu ekwehlisweni komhlaba wonke kwalesi gesi esibamba ukushisa emkhathini.
Ngaphezu kwalokho, ngemva kokunyamalala kwazo, lezi zilwane zicwila ekujuleni okukhulu; kuba ukudla kwezinhlobonhlobo zezinto eziphilayo zasolwandle, njengama-cetaceans nezimfudu. Imihlahlandlela yababhukudi lapho behlangana nama-salps.
Ukuqinisekisa inhlalakahle yama-salps, kubalulekile ukuthi ugweme ukuwathinta noma ukuwakhipha emanzini, njengoba angabhubha lapho esuswa endaweni yawo yemvelo ngisho noma engamele noma yikuphi usongo.
Ukuze ulondoloze isakhiwo sabo esibucayi, kunconywa ukuba ugweme ukuphatha, ngisho noma ingabangeli noma yimuphi umonakalo. Lapho abahlengi bebona amaqembu amakhulu ama-salps, Kubalulekile ukubazisa ukuze bakwazi ukwenza izenzo ezidingekayo futhi baqondise abanye ababhukudi.
Ukukhuthaza ukuvikeleka kanye nokongiwa kwama-salps ku-ecosystem kwenziwa lula ukuqonda okuphelele kwenani lawo lemvelo kanye nokubaluleka kwawo mayelana nokuqwashisa ngemvelo.
Ungawahlukanisa kanjani ne-jellyfish
Ama-salps anomzimba we-tubular futhi cishe obala ngokuphelele, ovumela ukuba bazifihle emanzini. Ngokungafani ne-jellyfish, ama-salps ahamba ngokufinyela, ampompa amanzi emzimbeni ukuze ahambe. Lesi senzo sokumpompa siphinde sivumele ukuthi zihlunge izinhlayiya zokudla emanzini, njenge-phytoplankton. Ama-salps avame ukutholakala kumaketanga amakhulu noma amakoloni antanta phezu kolwandle, okungenye yezici zawo ezihlukile. Ngaphandle kwalokho, Ama-salps awanawo amatende, okuwahlukanisa ngokusobala ne-jellyfish.
I-Jellyfish, ngakolunye uhlangothi, i-cnidarians, iqembu elihluke ngokuphelele lezilwane zasolwandle. Ukuma kwayo okuvame kakhulu ukuthi "isigqoko" noma insimbi enamatende alenga phansi. Amathente e-jellyfish ambozwe ngamaseli ahlabayo, okuthiwa ama-cnidocyte, abawasebenzisayo ukuze babambe inyamazane futhi bazivikele. Ngokungafani nama-salps, i-jellyfish ayiwakhi amaketanga antantayo. Ukunyakaza kwazo kunesigqi futhi kuguquguquka, ngenxa yokufinyela kwensimbi yazo, okuzivumela ukuba zihambe ngokuzimela emanzini.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi iyini i-salps nokuthi kungani iningi labo emabhishi aseCantabria manje.
