IDromicus ornatus, noma inyoka enombala onsundu, ingenye yezinyoka eziyivelakancane emhlabeni.
Ihlala kuphela kwelinye lamaqembu eziqhingi asoLwandle lweCaribbean futhi yathola igama elithile lokuhlonipha isiqhingi - iSanta Lucia. Inyoka yaseSentlucian ingeyezinhlobo eziyi-18 zezilwane eziyivelakancane ezihlala emhlabeni wethu.
Ukusabalala kwenyoka yaseSlimusian
Inyoka iSanta Lucia isatshalaliswe ngaphezu kwesiqingatha sekhilomitha esiqhingini esisogwini lwaseSanta Lucia, enye yamaLittle Antilles, uchungechunge lweziqhingi ezincane zentaba-mlilo ezisuka ePuerto Rico ziye eNingizimu Melika eCaribbean.
Izimpawu zangaphandle zenyoka yaseSlimusian
Ubude bomzimba wenyoka yaseSentlucian bufinyelela ku-123.5 cm noma amasentimitha angama-48.6 ngomsila.
Umzimba umbozwe isikhumba ngombala oguqukayo. Kwabanye abantu, umugqa onsundu obanzi ugijima emzimbeni ongenhla, kwabanye, umugqa onsundu uyaphazanyiswa, bese kuthi izindawo eziphuzi zishintshane.
Imikhakha yenyoka yesintluss
Izindawo zokuhlala zenyoka yaseSlimusian njengamanje zigcinwe endaweni evikelwe iMaria Major, okuyisiqeshana somhlaba esinezimo ezomile, okuyikhaya lamahlathi amakhulu we-cacti kanye nehlathi eliphansi elinamakhasi. Esiqhingini esikhulu saseSt. Lucia, inyoka iSanta Lucia ihlala emahlathini omile asezindaweni ezishisayo nezihlala ziluhlaza kusuka olwandle kuya kumamitha ayi-950 ngaphezu kolwandle. Uncamela ukuhlala eduze kwamanzi. Esiqhingini saseMaria, kukhawulelwe ebukhoneni ezindaweni ezomile ezinezihlahla nezihlahlana nalapho kungekho manzi amile unomphela. Inyoka yeSantus ibonakala kaningi ngemuva kwemvula. Kuyinyoka evundile.
Izimo zemvelo esiqhingini iMaria Island azikulungele kakhulu ukusinda.
Lesi siqeshana somhlaba sivame ukuba yisomiso neziphepho ezihlasela njalo le ndawo. IMaria Major itholakala ngaphansi kwamakhilomitha ayi-1 ukusuka eSanta Lucia ngakho-ke isengozini yezinhlobo ezisemaphandleni ezihlaselayo, kufaka phakathi ama-mongooses, amagundane, ama-possum, izintuthwane, kanye nezindlebe zomoba. Ngaphezu kwalokho, ingxenye enkulu yomlilo iyenzeka ngenxa yobuningi bezimila ezomile kulesi siqhingi. Isiqhingi esincane asikwazi ukuhlinzeka ngokusinda isikhathi eside kwalezi zinhlobo.
Umsoco wenyoka kaSenlucian
Inyoka yamaSentlucian idla izibankwa namaxoxo.
Ukukhiqizwa kabusha kwenyoka yamaSlimusian
Izinyoka zeSentlusian zizala cishe unyaka owodwa ubudala. Kepha izici zokuzalela kwesirhubuluzi esingavamile kufanele zichazwe ngokuningiliziwe.
Izizathu zokwehla kwenombolo yenyoka yaseSentlusian
Izinyoka ezinombala onsundu bake batholakala ngobuningi esiqhingini saseSt. Lucia, kepha kancane kancane bangeniswa ekupheleni kwekhulu le-19 yi-mongoose, ethanda ukuzingela izinyoka. Izilwane ezincelisayo ezidliwayo zafika esiqhingini zivela eNdiya zizobhubhisa izinyoka ezinobuthi, ama-mongoose adla zonke izinyoka ezihlala kulesi siqhingi, kufaka phakathi lezo ezingeyona ingozi kubantu.
Ngo-1936, inyoka yakwaSentus, eyayifinyelela kumitha elilodwa ubude, kwathiwa ayisekho. Kodwa ngo-1973, lolu hlobo lwenyoka lwaphinde lwatholakala esiqhingini esincane esinamadwala esigodliwe saseMary eduze nogu oluseningizimu yeSt. Lucia, lapho ama-mongoose engakaze afinyelele khona.
Ekupheleni konyaka we-2011, ochwepheshe baphenye kahle le ndawo futhi bathola izinyoka ezingavamile.
Iqembu lososayensi abayisithupha kanye namavolontiya amaningana bachitha izinyanga ezinhlanu esiqhingini esinamadwala, behlola yonke imiqansa nokudangala, okwaholela ekutheni bathole izinyoka eziningana. Bonke abantu abangajwayelekile babanjwa kwafakwa kubo ama-microchips - amarekhodi ongakwazi ukulandela ngawo ukuhamba kwenyoka. Imininingwane yezici zempilo yomuntu ngamunye izodluliselwa okungenani iminyaka eyi-10, kufaka phakathi imininingwane mayelana nokuzala kwabo neminye imininingwane engaziwa.
Ososayensi baphinde baqoqa amasampula e-DNA ukunquma ukuhlukahluka kofuzo kwezinyoka, ngoba lolu lwazi luyadingeka ohlelweni oluphumelela kakhulu lokuzalisa izilwane ezihuquzelayo ezingavamile. Ochwepheshe besaba ukuthi endaweni encane, izilwane ezihuquzelayo ziwela eduze, okuzothinta inzalo. Kepha uma kungenjalo, izinyoka bezizobona izinguquko ezahlukahlukene, ngenhlanhla, ezingakazibonakalisi ekubukekeni kwangaphandle kwezinyoka. Leli qiniso liyakhuthaza ukuthi inyoka yaseSenlucian ayisongelwa ngokonakala kofuzo okwamanje.
Izinyathelo zokuvikelwa kwenyoka yeGentleus
Ososayensi banesifiso sokuthola indlela engcono kakhulu yokulondoloza inyoka yeSentus. Ukwethulwa kwe-microchip kusiza ukulawula ukusebenza kwezilwane ezihuquzelayo ezingavamile. Kodwa indawo yesiqhingi incane kakhulu ukuthi ingahlalisa kabusha lolu hlobo.
Ukuthuthela kwabanye abantu esiqhingini esikhulu akulungile njengoba ama-mongooses asatholakala kwezinye izindawo futhi azobhubhisa izinyoka zaseSentlucian. Kukhona ithuba lokuthuthela ezihuquzelayo ezingavamile kwezinye iziqhingi ezingasogwini, kodwa ngaphambi kokwenza lokhu, kuyadingeka ukuthola ukuthi ngabe kukhona yini ukudla okwanele okusinda kwenyoka yeSaintlusian ngaphansi kwezimo ezintsha.
UFrank Burbrink, uprofesa wesayensi yezinto eziphilayo eStaten Island College, ngenkathi exoxa ngalo msebenzi, ukuqinisekisile ukuthi izinyoka kufanele ziyiswe kwenye indawo ukuze zivikele ikusasa lazo. Kuyadingeka futhi ukwenza umsebenzi wolwazi ofanele ukuze abantu bazi ngesimo senyoka yaseSentlusian, nokuheha amavolontiya azokwenza izenzo zemvelo.
Kepha ekuxazululeni le nkinga kungaba nobunzima obuthile, ngoba "lezi akuzona imikhomo noma izilwane ezi-fluffy ezithandwa ngabantu."
Inyoka yaseSaintluss ingabuyela esiqhingini esikhulu futhi ngemuva kokuvikelwa okunamandla nohlelo lokuzalanisa.
Kodwa-ke, njengamanje, lolu hlobo lwenyoka lusengcupheni enkulu yokuqothulwa endaweni engamahektare ayi-12 (amahektare angama-30), kuncane kakhulu ukuthi kungatholwa lolu hlobo.
Ukusinda kwenyoka yaseSlimusian kuncike ekusetshenzisweni kwezinyathelo ezinkulu zokuvikelwa kwemvelo. Indawo yokulondolozwa kwemvelo yasungulwa eMaria Islet ngo-1982 ukuvikela inyoka engavamile nezinye izinhlobo zasesiqhingini ekuqothulweni. IBritish International Flora and Fauna Conservation Group iphawule ngemizamo ephumelelayo yokongiwa kwemvelo yokulondoloza ezinye izinyoka ezingandile emhlabeni, njengenyoka iSentlusian.
Ngo-1995, kwabalwa izinyoka ezingama-50 kuphela, kodwa ngenxa yezinyathelo zokuzivikela ezithathiwe, inani lazo lakhuphuka laya ku-900. Kososayensi, lokhu kwaba yimpumelelo emangalisayo, ngoba inqwaba, uma kungenjalo amakhulu ezinhlobo zezilwane ezazivele zilahlekile emhlabeni, ngoba abantu babehlala kabusha izidlezane ezivela kwezinye izingxenye bengacabangi Umhlaba.
UMatthew Morton, iMenenja Yohlelo Lokulondolozwa Kwenyoka iSentleus, uqaphele:
“Ngomqondo othile, lesi yisimo esethusayo kakhulu ngabantu abancane kangako, esinqunyelwe insimu eyodwa encane. Kodwa ngakolunye uhlangothi, leli yithuba ... kusho ukuthi sisenalo ithuba lokusindisa lolu hlobo. "
