Inyoka kaDekeus (Storeria dekayi), noma inyoka ensundu, ingeye-scaly oda.
Incazelo yokuvela kwenyoka kaDekey.
Inyoka ensundu iyisilwane esihuquzelayo esincane esingajwayelekile ukudlula amasentimitha ayi-15 ubude. Osayizi bomzimba kusuka ku-23.0 kuye ku-52.7 cm, abesifazane bakhulu. Umzimba unamehlo amakhulu nezikali ezicijwe kakhulu. Umbala we-integument uvame ukuba nsundu ngokubomvu ngomugqa olula ngemuva, onqunyelwe ezinhlangothini ngamachashazi amnyama. Isisu simhlophe ngokubomvana. Imigqa engu-17 yesikali igijima maphakathi nendawo engemuva. Ipuleti lendunu lihlukene phakathi.
Iduna nensikazi zibukeka zifana, kodwa iduna linomsila omude. Kunamanye ama-subspecies amaningana we-Storeria dekayi abukeka ehluke kancanyana, kepha abukho ubufakazi bombhalo bokuthi kukhona ukwehluka kwesizini ngokombala. Izinyoka ezincane zeDekeus zincane kakhulu, ziyi-1/2 intshi ubude kuphela. Abantu banombala omnyama noma ompunga omnyama. Isici esivelele sezinyoka ezincane ngamasongo anombala ompunga ngokumpunga entanyeni. Kule minyaka yobudala, ahlukile kwezinye izinhlobo ezinamazinga akhenjiwe.
Ukusabalala kwenyoka kaDekeus.
Inyoka kaDekeus isakazeke kakhulu eNyakatho Melika. Lezi zinhlobo zitholakala eSouthern Maine, Southern Quebec, Southern Ontario, Michigan, Minnesota nasenyakatho-mpumalanga yeSouth Dakota, eSouth Florida. Ihlala ogwini lweGulf of Mexico, eMpumalanga naseningizimu yeMexico eVeracruz nase-Oaxaca naseChiapas eHonduras. Kuzala eningizimu yeCanada. Kusatshalaliswe e-United States empumalanga yamaRocky Mountains nasenyakatho neMexico.
Indawo yokuhlala yenyoka kaDekeus.
Izinyoka zikaDekeus ziningi kakhulu ezindaweni zazo zokuhlala. Isizathu ukuthi lezi ezihuquzelayo zincane ngosayizi futhi zithanda kakhulu izinhlobo ezahlukahlukene zama-biotopes. Zitholakala cishe kuzo zonke izinhlobo zomhlaba nezindawo ezingamaxhaphozi ezinhlobonhlobo zazo, kufaka phakathi amadolobha. Bahlala emahlathini asendaweni eshisayo. Imvamisa zihlala ezindaweni ezimanzi, kepha akuzona ezezinhlobo ezihambisana nemizimba yamanzi.
Izinyoka zikaDekey zivame ukutholakala phakathi kukadoti, phakathi kwama-hyacinths amanzi eFlorida, ngaphansi komhlaba noma ngaphansi kwezakhiwo nezakhiwo. Izinyoka ezinsundu ngokuvamile zicasha phakathi kwamatshe endle nasemadolobheni amakhulu. Lezi zinyoka zichitha iningi lezimpilo zazo ngaphansi komhlaba, kepha ngesikhathi sezimvula ezinamandla, kwesinye isikhathi ziyaphumela obala. Lokhu kuvame ukwenzeka ngo-Okthoba-Novemba nasekupheleni kuka-Mashi-Ephreli, lapho izilwane ezihuquzelayo zisuka ezindaweni zokulala ubusika. Kwesinye isikhathi izinyoka zikaDekeus zizifihla ngezinye izinhlobo, inyoka enebhande elibomvu nenyoka eluhlaza ebushelelezi.
Ukukhiqizwa kabusha kwenyoka kaDekeus.
Izinyoka zikaDekeus ziyizilwane ezihuquzelayo zesithembu. Lolu hlobo lwe-viviparous, imibungu iyakhula emzimbeni kamama. Insikazi izala izinyoka ezincane eziyi-12 - 20. Lokhu kwenzeka engxenyeni yesibili yehlobo, ngasekupheleni kukaJulayi - ekuqaleni kuka-Agasti. Abantu abasanda kuzalwa abakutholi ukunakekelwa kwabazali okuvela kubantu abadala futhi bashiywa bodwa. Kodwa kwesinye isikhathi izinyoka ezincane ezinsundu ziseduze nabazali bazo isikhashana.
Izinyoka ezinsundu ezisencane zifinyelela ekuvuthweni ngokobulili ngasekupheleni kwehlobo lesibili, imvamisa ngalesi sikhathi ubude bomzimba wazo cishe sebuphindeke kabili.
Kuncane okwaziwayo ngempilo yezinyoka ansundu endle, kepha ekuthunjweni abanye abantu baphila kuze kube yiminyaka eyi-7. Mhlawumbe ngasikhathi sinye bahlala endaweni yabo yemvelo, kepha izinyoka zikaDekeus zinezitha eziningi kakhulu, ngakho-ke ingxenye kuphela yenzalo ifinyelela ekuvuthweni.
Izici zokuziphatha kwenyoka kaDekey.
Ngenkathi yokuzalanisa, izinyoka zikaDekey zitholana emzileni wama-pheromones afihlwa ngabesifazane. Ngokuhogela, owesilisa unquma ubukhona bomlingani. Ngaphandle kwenkathi yokuzalanisa, izilwane ezinwabuzelayo zihlala zodwa.
Izinyoka ezinsundu ziyaxhumana ikakhulukazi ngokuthinta nephunga. Basebenzisa izilimi zabo zemfoloko ukuqoqa amakhemikhali emoyeni, futhi isitho esikhethekile esisemphinjeni siquma lezi zimpawu zamakhemikhali. Ngakho-ke, izinyoka ezinsundu zizingela kakhulu ngaphansi komhlaba nasebusuku, mhlawumbe zisebenzisa kuphela umuzwa wazo wokuhogela ukuthola inyamazane. Lolu hlobo lwesirhubuluzi luzwela ukudlidlizela futhi lubona kahle kahle. Izinyoka ezinombala onsundu zihlaselwa njalo amaxoxo amakhulu namaselesele, izinyoka ezinkulu, amagwababa, oklebe, izigaxa, ezinye izinhlobo zezinyoni, izilwane ezifuywayo nama-weasel.
Lapho izinyoka zikaDekey zizizwa zisongelwa, zithambisa imizimba yazo ukuze zibonakale zikhudlwana, zithathe isimo esinolaka, zize zikhiphe uketshezi olunuka kabi kwi-cloaca.
Ukudla kwenyoka yakwaDekey.
Izinyoka ezinsundu zondla kakhulu izikelemu zomhlaba, ama-slugs, neminenke. Badla ama-salamanders amancane, izibungu ezinemizimba ethambile namabhungane.
Izinyoka zikaDekey zinamazinyo nemihlathi ekhethekile ezibavumela ukuthi bakhiphe umzimba othambile womnenke egobolondweni badle.
Indima ye-ecosystem yenyoka kaDekeus.
Izinyoka ezinsundu zisiza ukulawula inani leminenke, ama-slugs, alimaza kakhulu izitshalo futhi azibhubhise. Ngokulandelayo, izilwane eziningi ezidlayo ziyazondla. Ngakho-ke, izinyoka zikaDekey ziyisixhumanisi esibalulekile sokudla ku-ecosystem.
Okusho umuntu.
Lezi zinyoka ezincane zingaba lusizo ngokulawula inani lama-slugs ayingozi alimaza amaqabunga ezitshalo ezilinyiwe.
Isimo sokulondolozwa kwenyoka kaDekeus.
Inyoka kaDekeus imelwe inani elikhulu kakhulu labantu elenza okungaphansi. Isibalo sezilwane ezihuquzelayo ezindala asaziwa, kodwa ngokungangabazeki singaphezu kuka-100 000. Lolu hlobo lwenyoka lusatshalaliswa endaweni (kuze kufike emakhulwini amahektha) ezindaweni eziningi. Ukusatshalaliswa, indawo ehlala insimu, inani labantu abancane nabantu abazinzile ngokuqhathaniswa.
Izimpawu ezifakwe kuhlu zenza kube nokwenzeka ukuthi inyoka kaDekeus ibe sezinhlotsheni ezinesimo sayo esingabangeli ukukhathazeka okuthile. Njengamanje, izinombolo zezilwane ezihuquzelayo akunakwenzeka ukuthi zehle ngokushesha okwanele ukuze izinyoka zikaDekeus zikwazi ukufakwa esigabeni esibucayi kakhulu. Azikho izinsongo ezinkulu kulezi zinhlobo. Kepha, njengazo zonke izinhlobo ezijwayelekile, inyoka kaDekea ithinteka ukungcoliswa nokubhujiswa kwezindawo zasemakhaya nezasemadolobheni. Akwaziwa ukuthi yiziphi izinyathelo ezithathwayo ukuqinisekisa ukusebenza kwezinyoka ezinsundu ngokuzayo. Lezi zinhlobo zezinyoka zibekezelela izinga eliphezulu lokucekelwa phansi kwendawo yokuhlala kahle, kepha yimiphi imiphumela elandelayo ngokuzayo engacatshangwa.
