Njoka yachikasu - mtundu wa njoka zopanda poyizoni zofalikira kumwera kwa Russia, za njoka zazing'ono. M'madera ena, amatchedwa njoka yamiyala yachikasu kapena njoka yamiyendo yachikasu. Izi ndi njoka zazikulu kwambiri pambuyo pa Soviet Union. Chifukwa chaukali wake, mimba yachikaso samasungidwa m'matumba komanso ngati chiweto. Komabe, njoka ya Yellowbelly imapindulitsa ulimi chifukwa imadyetsa makoswe omwe amawononga mbewu. Chifukwa cha izi, kuwonongeka kwakanthawi kwakanthawi, kudya mbalame ndi mazira awo, ndizochepa.
Chiyambi cha mitundu ndi kufotokozera
Chithunzi: Njoka Yakuda Yakuda
Njoka yamiyala yachikaso ndi njoka yayikulu, yopanda poyizoni kuchokera kubanja lofananira kale. M'mbuyomu, Colubridae sanali gulu lachilengedwe, popeza ambiri aiwo anali ogwirizana kwambiri ndi magulu ena kuposa anzawo. Banja limeneli lakhala likugwiritsidwa ntchito ngati "zinyalala" pazinyalala zosiyanasiyana za njoka zomwe sizikugwirizana ndi magulu ena. Komabe, kafukufuku waposachedwa wamankhwala a phylogenetics wakhazikitsa gulu la njoka "zakuthwa", komanso banja lomwe tsopano limatchedwa kuti monophyletic clade. Komabe, kuti mumvetsetse zonsezi, kafukufuku wina amafunika.
Chiyambire kufotokozedwa koyamba ndi Johann Friedrich Gmelin mu 1789, njoka yamiyala yachikasu idadziwika ndi mayina ambiri ku Europe.
Mndandanda wa mayina waperekedwa pansipa:
- C. Caspius Gmelin, 1789;
- C. acontistes Pallas, 1814;
- C. thermis Pallas, 1814;
- C. jugularis caspius, 1984;
- Hierophis caspius, 1988;
- Dolichophis caspius, 2004
Mitunduyi imaphatikizanso zazing'onozing'ono:
- Dolichophis caspius caspius - ochokera ku Hungary, Romania, kumwera chakum'mawa kwa dziko lomwe kale linali Yugoslav Republic, Albania, Ukraine, Republic of Moldova, Bulgaria, Greece, kumadzulo kwa Turkey, Russia, gombe la Caucasus;
- Dolichophis caspius eiselti - Kuchokera kuzilumba zaku Greek za Rhodes, Karpathos ndi Kasos ku Aegean Sea.
Ambiri a nkhonono sakhala ndi poizoni kapena alibe poizoni wosavulaza anthu.

Chithunzi: Njoka yamiyala yachikaso m'chigawo cha Rostov
Njoka yamiyala yachikaso imafikira kutalika kwa thupi lokwanira mamita 2.5, ndipo imawerengedwa kuti ndi yayikulu kwambiri ku Europe, koma kukula kwake ndi 1.5-2 m. Nsonga ya mphuno ndi yosalala komanso yozungulira. Lilime lalitali kwambiri komanso lochepa kwambiri. Mchira ndi wautali komanso woonda. Chiwerengero chonse cha kutalika kwa njoka ndi kutalika kwa mchira ndi 2.6-3.5. Maso ndi akulu ndipo ali ndi ana ozungulira. Mano maxillary amakhala osazungulira kutalika, motalika kumbuyo kwa nsagwada, mano awiri omaliza nthawi zambiri amasiyanitsidwa wina ndi mnzake ndi mpata wopapatiza.

Zambiri za biometric pamayeso oyeserera adawonetsa: kutalika konse (mutu + thunthu + mchira) mwa amuna - 1160-1840 mm (pafupifupi 1496.6 mm), mwa akazi - 800-1272 mm (pafupifupi 1065.8 mm). Kutalika kwa mutu ndi thupi (kuyambira kunsonga kwa mphutsi mpaka kumapeto kwa mkombero wamphongo) mwa amuna ndi 695-1345 mm (pafupifupi 1044 mm); mwa akazi - 655-977 mm (pafupifupi 817.6 mm). Kutalika kwa mchira: 351-460 mm (pafupifupi 409.8 mm) mwa amuna, 268-295 mm (pafupifupi 281.4 mm) mwa akazi. Kutalika kwa mutu (kuchokera kunsonga mpaka pakamwa): amuna 30 mm, akazi 20 mm. Kutalika kwa mutu (kuyeza pakati pakona pakamwa) ndi 22-24 mm kwa amuna ndi 12 mm kwa akazi.
Mimba wachikaso umadziwika ndi mamba osalala bwino. Mizere 19 ya mamba imapezeka mkatikati mwa thupi, ngakhale nthawi zina pamatha kukhala khumi ndi zisanu ndi ziwiri. Masikelo am'mbali amakhala ndi fossae ziwiri zam'madzi kumapeto kwake. Ndi opepuka pakati kuposa m'mbali. Msana wa njokayo ndi yofiirira ndipo uli ndi zipsera zomwe zimafanana ndi njoka zazing'ono, koma zimasowa ndi msinkhu. Mbali yamkati ndiyonyezimira kapena yoyera.

Chithunzi: Njoka yamiyala yachikasu
Njoka yamiyala yachikasu imapezeka ku Balkan Peninsula, madera ena akum'mawa kwa Europe kudera la Volga komanso gawo laling'ono la Asia Minor. Amatha kupezeka m'malo otseguka, nkhalango ndi nkhalango zamapiri, m'mphepete mwa nkhalango za steppe, m'tchire pafupi ndi misewu, m'chipululu, kumchenga ndi m'malo otsetsereka, pafupi ndi mitsinje yamapiri, pakati pa tchire lokutidwa ndi zomera, miyala ndi miyala, kutsetsereka kwa zigwa ndi zigwa. , m'mbali mwa mitsinje ndi m'mabango ouma.
Kumpoto kwa Caucasus, mimba yachikaso imalowera m'malo amchipululu okhala ndi milu ya mchenga. M'nyengo youma, imakonda kupezeka pafupi ndi mitsinje komanso m'madambo. Nthawi zambiri amakwawa kufunafuna chakudya ndi malo oti ayikire mazira m'mabwinja osiyanasiyana, kuphatikizapo mabwinja a nyumba, nyumba zomangamanga kapena nyumba zokhalamo anthu, pansi pa nkhokwe, minda, minda yamphesa ndi malo ena ofanana. M'mapiri, imakwera mpaka kutalika kwa 2000 m. Ku Caucasus, imapezeka kumtunda kuyambira 1500 mpaka 1600 m.

Habitat imatha kugawidwa m'malo otsika pafupi ndi mitsinje ikuluikulu monga Danube ndi Olt River. M'mbuyomu zimaganiziridwa kuti njoka yamiyala yachikaso idasowa ku Moldova, kum'mawa kwa Romania ndi kumwera kwa Ukraine, komwe kuli malo awiri okha omwe amadziwika ndipo njokayo sinakhalepo kuyambira 1937. Komabe, zitsanzo zitatu zidasonkhanitsidwa mu Meyi 2007 m'chigawo cha Galati ku Romania.
Ku Hungary, m'mbuyomu anthu amaganiza kuti Yellowbelly amakhala m'malo awiri okha, koma kafukufuku waposachedwa m'derali wapeza malo angapo osadziwika kale a njoka izi mumtsinje wa Danube. Kummwera kwa Crimea pali pafupifupi 1 specimen pa 2 km², kumpoto kwa Dagestan - 3-4 njoka pa km², ndi kumwera kwa Armenia - pafupifupi 1 specimen pa 1 km².

Amadyetsa makamaka abuluzi: miyala, nimble, Crimea ndi mchenga. Nthawi zambiri, anapiye, mbalame ndi mazira awo. Ndiponso ndi makoswe: agologolo aganyu, makoswe, mbewa, ma gerbils, hamsters. Nthawi zina njoka zina zimaphatikizidwamo, kuphatikizapo zoyizoni: njoka yamphongo wamba ndi mchenga epha, yemwe njoka yoluma yachikasu imamuluma. Njokayo imadyetsa nyama za m'madzi kawirikawiri; imagwira achule m'malo amvula. Tizilombo tazikulu ndi akangaude amathanso kukhala ozunzika pamimba wachikaso.
Njokayo imatha kudutsa m'mabowola amphaka ndi kuwawononga. Pofunafuna chakudya, imakwera mumitengo, pomwe imawononga zisa za mbalame zomwe sizikukwera kwambiri, koma nthawi zambiri zimasaka mbalame zomwe zimakhala pansi. Ku Crimea, chakudya chomwe amakonda kwambiri njoka zokwawa ndi abuluzi, njoka ndi nyama - agologolo agulu, zikopa, ma voles, mbewa, ma hamsters.
Chosangalatsa: Kudera la Astrakhan, njoka yoyipa yomwe imapezeka m'zigawo zapululu imadyetsa abuluzi am'madzi ndi matenda ofulumira a miyendo ndi pakamwa (31.5%), buluzi wofulumira (22.5%), munda ndi khungu, komanso khungu lakuda (13.5%), omelet (9%), agologolo (31.7%), ma gerbils (18.1%), mbewa (13.5%), hamsters (17.8%) ndi tizilombo ndi akangaude.

Njoka zamiyala yachikaso zimadutsa m'malo obowola mbewa ndi malo ena okumbapo dothi. Hibernation imatha pafupifupi miyezi isanu ndi umodzi. Pa tchuthi chachisanu, nthawi zambiri anthu opitilira khumi amasonkhana pamalo amodzi. Mimba wachikaso umachoka pogona kumapeto kwa Epulo - koyambirira kwa Meyi, ndikuyamba kuwonetsa zochitika mu February - Marichi, kutengera malowa, mpaka Seputembara-Okutobala. Ku Crimea ndi North Caucasus, njokayo imawonekera pamwamba patatha nthawi yozizira kumapeto kwa Marichi - koyambirira kwa Epulo, kumwera kwa Ukraine - mkati mwa Epulo ndi ku Transcaucasia kumapeto kwa Okutobala.
Njoka yamiyala yachikaso ndi njoka yopanda ziweto masana yomwe imakhala padzuwa, pang'ono pamthunzi pang'ono ndi zitsamba, ndipo imabisala poyembekezera abuluzi. M'ngululu ndi nthawi yophukira, njokayo imagwira ntchito masana, ndipo nthawi yotentha, nthawi yotentha kwambiri masana, imakhala, ndipo imagwira ntchito m'mawa ndi madzulo. Njoka iyi ndiyofulumira kwambiri m'zinyama zathu, ikuuluka mwamphamvu kwambiri kuti isamawonekere. Kuthamanga kwa mayendedwe kumalola mimba yachikaso kuti igwire nyama yothamanga kwambiri.
Chosangalatsa: Chizindikiro chamakhalidwe oyipa a njoka yamiyala yachikaso ndi nkhanza zodabwitsa. Zina mwa njoka za nyama zathu, njoka izi (makamaka zamphongo) ndizoopsa kwambiri komanso zovulaza. Samayesa kubisala pamene munthu ayandikira, monga momwe njoka zina zimachitira, koma amapindika m'miphete, monga njoka zapoizoni, ndikuponyera 1.4-2 m, kuyesa kugunda kumaso.
