Nhengo dzepabonde mumakamba

Varidzi vane zvipfuwo zvavanofarira - turtles, vanofarira nyaya yekuberekesa nhapwa, iyo inosanganiswa nekugadzirwa kwenhengo dzepabonde uye "kuroorana" maitiro. Kugadziriswa kusina kujairika kwemuviri wemhuka pachayo kunoreva kuti hurongwa hwekubereka hwakarongwa nenzira yakasiyana. Kufanana nezvimwe zvinokambaira, kamba dzinokandira mazai, asi izvozvo zvisati zvaitika, kuberekesa mukati kunoitika.

murume chibereko

Sezvo marudzi mazhinji emhuri yekamba achirarama kwenguva yakakwana, gadziriro yokubereka nayo inosvika pakukura zvishoma nezvishoma, ichiumba pamusoro pechiverengero chamakore. Nhengo dzesikarudzi dzekamba dzinoumbwa nezvikamu zvinoverengeka:

• testes;
• testicular appendages;
• spermaduct;
• copulatory organ.

Inowanikwa pakati pechikamu chemuviri, hurongwa hwekubereka huri pedyo neitsvo. Kusvika pakuyaruka, vanenge vachiri vacheche. Nokufamba kwenguva, nhengo dzesikarudzi dzinokura uye saizi yavo inowedzera zvakanyanya. Muvanhu vakura, machende anotora chimiro cheovha kana cylinder; mumhuka duku, dzinoita sokunge kukora zvishoma.

Mune turtle yechirume, 4 nhanho dzekuvandudzwa kwehurongwa hwekubereka dzinosiyaniswa:

• regenerative;
• progressive;
• accumulative;
• regressive.

Zvikamu zvitatu zvekutanga zvinoratidza kukura kwema testes. Urume hunopinzwa muvas deferens, iyo inofamba ichienda ku cloaca, yobva yapinda muchombo. Kana murume amutswa, mboro yekamba yakazvimba inoenda kunze kwe cloaca uye inoonekwa kubva kunze.

Mhuka dzemvura nedzepasi dzinosiyaniswa nemboro hombe. Nekuita zvepabonde, "inokura" ne50%. Mune mamwe marudzi, hukuru hwayo hunosvika hafu yehurefu hwemuviri wavo. Zvinotendwa kuti nhengo yepabonde inodiwa kwete chete kubatanidzwa, asi inoshandiswawo pakutyisidzira. Asi kana nguva yekunzwa kuda zvepabonde yapera, peni yekamba inovanda pasi pegoko.

Cherechedzo: Nhengo yesikarudzi yekamba yechirume inoenda kunze kwemuviri panguva yekunakirwa pabonde uye kukwirana, yozodzokera mukati zvishoma nezvishoma. Kana izvi zvisingaitike, saka turtle ine matambudziko ehutano, kukura kwezvimwe zvirwere zvinogoneka.

Vhidhiyo: mboro yemurume ane nzeve dzvuku

Reproductive system yevakadzi

Mune turtles dzechikadzi, hurongwa hwekubereka hunoumbwa nemadhipatimendi anotevera:

• mazambiringa akafanana nemazambiringa;
• elongated oviduct;
• shell glands dziri munzvimbo dzepamusoro dze oviducts.

Maovari ari pedyo neitsvo uye ari mukati mechikamu chepakati pemuviri. Kukura kwavo kunoitika zvishoma nezvishoma, uye ukuru hunowedzera panguva yekuyaruka. Kune mhuka dzinovaraidza, iyi izera re5-6 makore. Muvakadzi, panguva yekubatana, nhengo dzose dzepabonde dzinoputika, dzichiwedzera zvakanyanya.

Iyo turtle haina chibereko, nokuti intrauterine kubereka kwevechidiki haina kugadzirwa. Iyo yolk yezai inoumbwa nekuda kwechiropa, iyo inoigadzira uchishandisa adipose tissue. Maviri akaenzana oviducts anobatana pa cloaca. Vanobatanidzwa:

• mukufamba kwemazai;
• mukugadzirwa kwehombodo dzemangwana embryo;
• mukuchengetedza urume;
• zvakananga mukuita kubereka.

Pamberi pechivharo pane sikarudzi yekamba. Iyi elastic muscular chubhu inogona kutambanudza uye kudonha. Pano, urume hunogona kuchengetwa kwenguva yakareba uye kusangana kunogoneka kana zai richikura nekuda kwembeu yakachengetwa isati yachengetwa, uye kwete panguva yekubatana.

Zai rakasangana nembesa rinofamba zvishoma nezvishoma kuburikidza neoviduct uye zai rinoumbwa kubva mairi. Masero echikamu chepamusoro che oviduct anogadzira mapuroteni (protein coat inogadzirwa), uye shell inoumbwa pamutengo wechikamu chezasi. Pane zviitiko apo vakadzi, pasinei nekuvapo kwemurume, vanoisa mazai asina kubereka.

Kune 4 nhanho mukuvandudzwa kweiyo yekubereka system yekamba:

• kukura kwe follicles muhukuru;
• nzira ye ovulation;
• kubereka kwakananga;
• kuderera.

Kuwedzera kwefollicles ndiyo mhedzisiro ye ovulation (kuumbwa kwezai), inoteverwa nehurongwa hwekusangana, uyezve kudzoka kunoitika.

Cherechedza: Kana hadzi ikandira mazai ayo, nguva yayo yokubereka inopera uye gadziriro yokubereka nayo inosvika pakugadzikana. Kuchengeta vana hakusi kwezvinokambaira, saka amai vacho havafariri kuti vana vavo vachazvarwa riini uye sei.

Kurera Turtle

Kamba hadzina kubereka zvakanaka mukutapwa. Kuti vaite izvi, vanofanira kugadzira mamiriro ezvinhu ari pedyo nemamiriro ezvinhu echisikigo. Nekudya kwakakodzera, yakanaka microclimate uye yakasununguka kufamba kwakasununguka, maitiro ekubatana kwezvikara zvinokambaira zvinogoneka. Vanokwanisa kuita zvepabonde gore rose.

Kazhinji, semhuka yemhuka, vanochengeta turtle yemvura ine nzeve dzvuku. Vanhu vevanhurume vakasiyana vanoiswa mune yakajairika terrarium uye inotariswa kana hukama hwakatangwa pakati pevaviri. Kazhinji, vakadzi vakati wandei vanodyarwa nerume panguva yekusangana. Murume, kusiyana nehadzi, ane muswe murefu uye notch paplastron.

Munguva yezvepabonde, maitiro evanhu anoshanduka zvakanyanya. Vanowedzera kushingaira uye vanorwa. Semuenzaniso, varume vanogona kurwira mukadzi.

Nhengo dzepabonde dzehutu-tsvuku-nzeve hadzina kunyanya kusiyana nemamwe marudzi.

Panguva yekubatana, murume anokwira kumukadzi uye anobaya seminal fluid mu cloaca yake. Mumakamba emumvura, kukwirana kunoitika mumvura, asi mukamba dzemuvhu, panyika. Nzira yekuberekesa inoitika mumuviri we "amai vamangwana". Panguva yekuzvitakura, anoparadzaniswa nemurume, uyo anova nehasha.

Cherechedza: Kubva panguva yekusangana kusvika pakukandira mazai, mwedzi miviri inopfuura. Asi mazai anogona kuramba ari mumuviri wehadzi kwechinguva kana ikasawana nzvimbo yakakodzera yekuaisa. Munzvimbo yakasikwa, turtle inosarudza masonry nzvimbo iyo iyo pachayo yakaberekerwa.

Iyo yekubereka sisitimu yakarongedzwa zvakakwana uye inobvumidza iwe kubereka pasi pemamiriro akanaka ekunze kakawanda pagore. Asi sezvo mazai nenyana zvinochochonya zvisina kudzivirirwa naamai, vana vakawanda vanofa nezvikonzero zvakasiyana-siyana. Naizvozvo, anosvika gumi nemaviri marudzi akanyorwa muRed Book nhasi, uye mamwe akachengetedzwa mune imwe chete makopi.
