Nondo nyanga (ona mufananidzo). Sei yenondo nyanga? Kana poro rakadeurwa nyanga dzavo?

Nyanga - a nevamwe chiratidzo rinozivisa mhuka, nezvimwe vamiririri fauna of uye anovapa mufananidzo runako uye kwamachinda. Ndechipi chinangwa hwakasimba kukura? Sei uye kana nondo nokuteura nyanga dzavo? Musiyano pakati growths dzakadaro vamiririri siyana mhuri Cervidae? Mhinduro dzemibvunzo iyi nemimwe mibvunzo zvichakurukurwa munyaya pazasi.

Horn - Kuzvikudza nondo

Deer antler - chinhu anozvikudza chete varume vemhuri Cervidae. Asi pane kunze, apo dzimwe subspecies growths varipo uye ruvara hadzi vanhu. Izvi zvinosanganisira Somuenzaniso, poro.

Nyanga kwete mhango sezvo mombe, kuva cellular yakarongeka. By uwandu pezvakaitwa vanogona kuona makore mhuka. Handiti, nhamba matavi uye kukura nyanga pachavo vari kuwedzera kubva gore negore.

Adults vamiririri Cervidae mhuri pagore pashure kuguma Rut kuti ndiye maberekero mwaka anodonha growths dzavo pahuma. Pashure paizvozvo, pane nyanga matsva mhuka. Panguva kukura kwavo akafukidzwa akatunhidzwa uye anenge ganda. Rine yakawanda tsinga kuti uvake muviri cornea uye pfupa dzinobatsira ayo kusimbiswa.

Sei inyanga nondo?

Mugore rokutanga muupenyu hwishu pahuma yake ikure bulges maviri, sezvinoita bhatani. Vari kunzi "Makumbo" uye varipo pamusoro pechibayiro muupenyu hwake hwose. Muchirimo "mabhatani" izvi kutanga kukura nyanga, izvo panguva zhizha kuwedzera zvikuru kukura. First kuonekwa zvakananga pezvakaitwa, izvo vacharamba kubazi panze.

Young pasikweya kutsvetera nematehwe cover. Saka ivo nemaziso kuzviratidza kuva nyoro uye velvety. Munguva matsutso cuticle ichi anofa, uye akazaruka pachena pfupa. muduku nondo nyanga akafanana avo kuti vashongedze vakuru vakuru. Zvisinei, protuberances izvi dzinosiyana kukura chaizvo maduku uye uwandu kwendangariro.

Sei yenondo nyanga?

Large mapazi nyanga mhuka idzi dzine zvakawanda kushanda, rimwe riri kudzivirira pavavengi. Deer kashoma kushandisa growths avo pamusoro wake garo. Zvisinei nondo nyanga kuva zvinoorora saizi, ushande pazvikara kutyisidzira, uye kwete mhuka dzose anoshinga kurwisa akaripfeka.

Uyewo, mapfupa growths pahuma kuti vamiririri mhuri Cervidae rinowanzoshandiswa kuva mudziyo kuti pagadzirwe imwe zvokudya muchando. Somuenzaniso, kuti vave kufarira poro chikwindi, vamiririri kuchamhembe subspecies kuchera chando nayo nenyanga dzaro.

Chimwe chinangwa protuberances pamusoro nondo - kubatanidzwa kurwa inoenderana varume Rut. Ndiyo apo Nondo kushandiswa nyanga kuti muvengi rokukuvadza. Munguva kuberekesana mwaka mhuka vanorwisa nemuvengi wake uye anoita zvikuru utsinye. Vakundwa mukono ropa, uye Kumukundi awana wokushamisira kodzero zvisangane nomukomana hadzi.

Kana uye nei Nondo rakadeurwa nyanga dzavo?

Dzimwe musango unogona kuona inobviswa nyanga (mufananidzo pazasi). Muitiro ndichiva kubvisa yekare outgrowth anogona kuenzaniswa kuipa molting, izvo tinoberekwa mhuka dzakawanda. Nyanga pamusoro wemhuka - mupenyu muviri. masero Its kukura, kamura uye kufa. In zvimwe nguva woupenyu yenondo antler nechigadziko mhete aumbwa kuti kunotadzisa aibuda ropa, iro ndakavapa muviri.

Muitiro uchisiya Nondo zvakasimba outgrowths kunotanga yokuti vakapamura kure vaduku zvimedu. Ukuru zvidimbu izvi muparadzane kuri kungoramba. Uye pane imwe nguva nyanga zvinopedzwa zvachose. Izvi zvinoitika mushure kuguma kuberekesana mwaka, izvo vamiririri mhuri Cervidae kunotora December kusvika February. Muchirimo nondo anokura nyanga itsva. Izvi zvinoda vaviri mwedzi mina.

Kuti rikurumidze anoteura nyanga mhuka varikwizire pamusoro muti hunde dzacho, stumps, ivhu, matanda kana mabwe makuru. Mukuru nondo hono, nokukurumidza ari kuedza kubvisa mapazi zvinoshandiswa. Pashure pezvose, vanhu vakura mumakore, kuva zvakaoma kutakura kurema akadaro pamusoro wake.

Dzimwe nguva zvinoitika kuti pashure izvi nondo pahuma yake anoramba zvikuru guru kukamuka nyanga. Izvi zvinogona kukonzera kusanzwa, nekuti musoro mhuka kuti kuteura kune rimwe divi uye achava kuvhiringidza rusununguko rwokufamba. Pakadaro, mukono achaedza kubvisa masangano anenge asara, akadai stachivaya ibwe rake.

Deer nyanga

nondo nyanga dzinotanga kukura uye tichiswedera pedyo pakati April. Atova May, nyanga urefu (vechiduku outgrowths) anenge 10 masendimita. Muzviuru muzhizha, vanoramba kukura kwavo nokukurumidza uye muna August zvasvika kwayo kukura. By zhizha mushakabvu, nyanga vanosunungurwa kubva ganda.

Maererano nezera zvinoitwa ichi subspecies ose nondo nyanga, nondo gore upenyu rokutanga varipo mumusoro "machisi" kana "panhengo", wakareba rinosvika 15 masendimita. Mumakore gumi mwedzi panyanga tsvuku nondo anozviratidza pamusoro 3 muitiro. Mune ramangwana, bazi zvichawedzerwa rimwe gore kuti nguva apo mhuka zvazadziswa makore 7.

Deer rakadeurwa nyanga dzavo dzose gore. Zvinotora nzvimbo muna March-April, dzimwe nguva muna February. Kazhinji, asati ava kubvisa akare outgrowths zvirume famba miti uye vachidzipukuta pamusoro wake. Panyaya iyi, musi hunde dzacho dzose nemakwati wakaremara, uye varipo dzakananga Tags akasiiwa antler (mapikicha zvinogona kuonekwa pazasi).

Muitiro vachidonhedzera outgrowths kuchinjwa zera uye mamiriro ezvinhu yenondo chaiko. New nyanga dzinotanga kukura mumazuva 5-10 pashure akamunzwira akwegura.

Elk runyanga

Elk akabata huru branching nyanga foshoro chimiro. growths kwakadaro vari yakashongedzwa musoro varume chete. Elk nyanga nhaka anoyevedza saizi. Nokuda kwavo uremu kusvika 20 makirogiramu uye inogona kusvika mamita rimwe nehafu.

Runyanga duku mhuru nyoro. menzvimbo ravo rine nhumbi ropa, uye kunze - kusimba ganda uye nyoro dzemakwai. Kana musikana kukuvadza growths avo pamisoro yavo, ivo achingobuda ropa. Panyaya iyi, mhuka iri kushushikana marwadzo. Gare gare, mumwe wechiduku Stony nyanga kuva kusimba, vanoonekwa bazi. Asi chimiro nefoshoro outgrowths achiva chete gore rechishanu upenyu.

Yose August uye September Elk iyo boka richitora mazamu kunoitika pakupera iyo nguva nastaot vachidonhedzera nyanga. Animals kubvisa akare outgrowths pakutanga kuchitonhora munguva. Izvi hwezvekukurukurirana zvikuru upenyu Stony, nekuti yechando zvaizova zvakaoma kufamba famba pamwe inorema nyanga akafukidzwa nesinou.

Akabatana nyanga, kuchamhembe uye makwapa nondo

Akabatana - nondo pamwe nyanga forked. It kunoratidzwa rinoshamisa nyasha. Akabatana trohkonechnye nyanga dzine refu stumps uye akapeta zvakasimba shure. Outgrowths kunge forked hunde uye frontal muitiro pakureba kwazvo. nondo izvi kurasa nyanga muna August.

Reindeer outgrowths pahuma anozvikudza vanhurume nehadzi. Horn kwevacheche dzinotanga kukura pazera mavhiki maviri. varume vaduku havana mune tsika, kubvisa zvokufonongonwa protuberances pahuma muna January. A varume vakuru kuita izvozvo panguva pakuguma kuberekesana mwaka, iyo inotanga muna September-November. Vakadzi vakateura growths mumusoro wake pashure calving, riri pakati May - June. New poro nyanga dzinotanga kuumbika muna August, uye muna September ari mbava kure navo.

Makwapa nondo ndiyo subspecies kupfuura kare mumhuri Cervidae, uye saka nyanga dzavo vane nyore yakarongeka. In outgrowths pamisoro yavo haisi supraorbital muitiro wechipiri uye korona. Nyanga sika nondo havana kupfuura nemapazi mashanu. Growths pahuma mhuka idzi varipo chete varume.

Sei achagura poro nyanga?

The poro mapurazi vane misoro mhenyu nondo nyanga kutema. Izvi wechidiki nondo nyanga, achigere aiva nguva ossify. Nemisoro mhuka vakaurayiwa nyanga mushoma windshields kuti vanofanira kubviswa kubva dehenya chinyorwa.

Kubva izvi vaduku nyanga akaita Pantocrinum - mishonga inokanganisa tsinga uye inoshandiswa kurapa zvirwere zvakasiyana-siyana.

Ripe nyanga dzinoratidzwa nokuvapo aparadzana mapazi, vane kuzvimba donhwe serin'i kumugumo. Pamusoro pezvakaitwa hakufaniri ribbed. Nyanga zvakafanira okusimba Ndinoonga zvikuru. Kana wechiduku nondo nyanga zvakakurira zvakakwana, zvivako zvavo somushonga haana kutaurwa zvizere simba. Izvi zvinoshandawo perespevshih nyanga kuti kare wakawana ribbed marongerwo uye miromo anorodzerwa.

Mushure achicheka vaduku nyanga manyoro akatuma marara kana zvomumagaba kushandiswa pave paya.

mhedziso

Deer antler - chinhu ichocho inoita mufananidzo mhuka iyi yakanaka uye anokudzwa. Hard growths pamusoro wechipiriso Cervidae vamiririri mhuri varipo kunyanya varume, kunyange zvazvo pane kusaina. Deer nyanga inoshandiswa kurwira yokupara munhukadzi. Uyewo growths pahuma mhuka idzi kuvabatsira kuti vazvidzivirire pazvikara uye kuwana zvokudya kubva pasi chando. Nyanga ose Elk yenondo zvapfuura kana wakapfuura pamberi kuberekesana mwaka. It kunoitika zuva chando - mangwanani yechirimo. Uye muvhiki mbiri kusvika mwedzi mina pamusoro nondo musoro, growths itsva.
