mitundu ya beavers

Kuti tsiku limene pali mitundu iwiri: za Beaver Canada, mtsinje otter (European). Pakati pa iwo okha, ali wofanana kwambiri, koma kuti pang'ono woyamba kwambiri. Atangotuluka Zafalikira Europe, North America ndi ku Asiya, koma lero anthu akuchepa kwambiri. Izi mlandu munthu amene anakonza nyama ya nyama zimenezi chifukwa cha ubweya awo ndi nyama.

Kusiyana pakati Canada ndi European Beaver

Onse mitundu nthumwi kuwoneka mofanafana kwambiri, ngakhale Eurasian waukulu. Iwo ali zazikulu ndi zochepa ozungulira mutu, kuipanikiza pamene wamfupi. Komanso, mchira kale, ndi zochepa undercoat. Komanso, Eurasian miyendo yaifupi, chotero, iye anali kusuntha zoipa miyendo yawo yakumbuyo.

Pafupifupi 70% ya ochiritsira Beaver bulauni kapena kuwala bulauni mtundu wa ubweya, ndi 20% Red, 8% ndi woderapo mtundu, ndi% 4 ubweya wakuda. Theka la beavers Canada kuyatsa bulauni khungu kamvekedwe, 25% ndi zofiirira ndi 5% wakuda mthunzi.

Mu Beaver wamba mafupa amphuno yaitali, ndipo mu mawonekedwe triangular m'mphuno, pamene Canada ndi mipata triangular. The azungu ndi zopangitsa kumatako amakhala akuluakulu. Komanso, pali kusiyana mu mtundu ndi ubweya.

Atafufuza mobwerezabwereza anayesa kuwoloka American ndi Eurasian mwamuna wamkazi, mkazi kapena ayi pakati ndipo anabereka ana akufa. Ambiri mwina, sikutheka interspecies kuswana. Pakati pa anthu awa si chotchinga dera lawo, komanso kusiyana mu DNA lapansi.

Kuwonjezera kusiyana kunja, deta ku ziwalo ziwiri za banja, pali kusiyana topangira DNA. Choncho, Canada beavers makumi DNA khromozomu zawo nambala 48. Various ndi chifukwa cha deta analephera kuwoloka kuchokera m'mayiko osiyanasiyana.

Kusiyana kwina pakati Beaver akhoza ankaona tsoka: Canada Beaver akumanga khoma si choncho, amalenga plotinischi yaikulu poyerekeza ndi nyumba ya m'bale wake Europe. nyumba akhoza anatambasula ndi kutalika mamita mazana angapo. Chifukwa lero Beaver Canada ku Russia mwachangu zidzaze m'madera a nyumba zawo ukasintha anasintha chilengedwe. Chifukwa cha damu pa madera ozungulira anachititsa madzi osefukira, ndipo kodi chidwi: ang'onoang'ono anadutsa ya anthu, m'pamenenso zone ya chikoka! Iwo kusintha chidzalo cha mitsinje ndi zotsatira mavuto onse zachilengedwe. Komanso, vandals Canada "kutchetcha" inali pafupi ndi nkhalango, ndipo iwo amapanga gombe ndi zambiri zofunika kwambiri zachilengedwe china. Komanso, beavers ku minda pafupi ndi minda boma ndi kuba yokolola, ndipo pali ponseponse mu njira iliyonse.

inafikira

Beaver Canada opezeka mu Alaska (North America), kupatula kumpoto, kumpoto chakum'mawa ndi kum'mawa m'malire; mu Canada; mu United States kulikonse, kuwonjezera Florida, mbali yaikulu ya Nevada ndi California; kumpoto kwa Mexico. Komanso anayambitsa maiko osiyanasiyana Denmark. Ku Finland amaloŵa m'dera Leningrad ndi Karelia. Kumene kunachitika Sakhalin ndi Kamchatka, ndi Amur beseni.

njira ya moyo

njira Yake ya moyo wofanana ndi wa Eurasian. Canada Beaver ndi kukangalika usiku, koma nthawi zina amapezeka masana ndi zina ukusunthira kutali madzi. Ziweto madzi zodabwitsa ndi kusambira m'madzi ndipo kungakhale kwa mphindi khumi ndi zisanu. Beavers amakhala m'mabanja a anthu mpaka eyiti - awiri kholo ndi ana ake. Juveniles kukhala ndi makolo awo kwa zaka ziwiri. Mabanja nthawi Kupititsa ndi kuteteza dziko lawo ndi mbali yotsala ya nyama.

Chiwembu malire zaikidwa Beaver kwakusiyana (chinsinsi kumatako zopangitsa), omwe umagwiritsidwa ntchito pa n'chodabwitsa a matope ndi matope. Pamene ngozi ya nyama anagunda mchira pa madzi, motero alamu. Monga Eurasians moyo mwa tinyumba ta amene anamanga nkhuni, wothira mafuta lapansi ndi matope. Ku manyumba ogona ndime pansi madzi; amene pansi ali ndi khungwa, tchipisi mitengo ndi udzu. Canada Beaver kamakumba una zikukhazikitsa zochepa kwambiri kusiyana ndi msuweni wake Eurasian. Zonse mlingo otaya ndi madzi mlingo zimamanga pa nthambi mitsinje damu, mitengo, matope, miyala, dongo. Canada kwa mphamvu zawo kwambiri yomanga.

kubalana

Kawirikawiri, beavers amakhala m'mabanja wopangidwa mwa akazi ndi amuna, komanso m'mbuyomo ndipo panopa zaka wamng'ono. kuswana nyengo m'madera ambiri - January-February. ana a chaka chatha, amene mu nthawi ino mozungulira zaka ziwiri, njuchi ndi anathamangitsa kufunafuna chitetezo kwina kulikonse, komanso nsapato zake.

Nthawi gestation masiku 107, ndi ana aamuna mongoyembekezera tinasamukira wapadera dzenje kubadwa wa mbewu nthawi kuchokera April kuti June. Anabadwa kuchita inadzachitika masiku angapo, makamaka kuwala limawonekera 5 Beaver. Kids zophimbidwa ndi tsitsi, iwo anali cutters noticeable, maso otseguka. Wangobadwa, bobryata kale amapita mwakachetechete m'madzi chifukwa kusambira kuyambira penipeni. Kuchuluka yaikulu ya akulu monogamous, awiri akhoza kuswa yekha ndi imfa ya mnzawo.

chakudya

Canada kapena North America, Beaver amadya chakudya chokha zamasamba. Iwo kudya nyama mphukira ndi makungwa a mitengo, osankhidwa msondodzi, Aspen, birch ndi popula. Komanso, kudya ndi mitundu yonse ya zomera herbaceous (chigubu, kakombo, cattail Iris, bango, etc., Mpaka maudindo mazana atatu). A nambala yaikulu mitengo softwood - chofunika malo awo. Linden, otuwira, chitumbuwa, Elm ndi mitengo ina mu zakudya zawo ndi zofunika sekondale. Oak ndi alder, iwo sadya nthawi yomweyo ntchito kwa nyumba zawo. Kuchuluka chakudya tsiku ndi tsiku ndi kuti gawo limodzi mwa magawo a kulemera kwa chinyama. Wamphamvu kuluma ndi mano lalikulu kulola beavers mosavuta kupirira zakudya olimba mbewu.

Pa chilimwe, zakudya beavers kugawana herbaceous forage ukuwonjezeka. Mu kugwa iwo zikugwira yokonza chakudya pa ozizira. M'matangadza aika mu madzi, kumene iwo angathe February kusunga makhalidwe awo wapatali zakudya. Kuti adyetse mu ayezi kuti amaundana, beavers madzi izo pansi chinsalucho itsike mpaka m'munsi mabanki phompho pansipa madzi. Choncho ngakhale pamene kuzizira dziwe chakudya amakhalabe zilipo pansi ayezi wandiweyani.

mphamvu

Canada Beaver, mosiyana ndi Eurasian, amene anali pafupifupi mwathunthu kudula, anavutika zochepa kwambiri. Si kuteteza mitundu limakhudza; chiwerengero chake chifikira anthu 15 miliyoni, koma isanayambe wa kulamulira wa North America, panali nthawi zoposa khumi. Nyama zimenezi zinali ankasakidwa amagwira nyama ndi ubweya, ndipo ndicho chiyambi cha m'ma chakhumi ndi chisanu ndi chinayi zinachititsa kuti kuchepetsa mofulumira malo awo achilengedwe. Ndiye, chifukwa cha achire komanso kusamala ntchito, chiwerengero chawo okwana wakula kwambiri.

Man ndi Beaver

Kukhala undercoat wapadera, ndi loyenereradi zikhalidwe nyengo Russian ndipo akhoza kuteteza anthu ku nyengo iliyonse. malaya amenewa masokosi khalidwe (amaona imodzi muyezo waukulu mu utsogoleri wolowezana wa tsitsi wapatali) chimaposa ngakhale burrow. Komanso, Beaver sakuopa chinyezi, ndipo mwa tsitsi ndi osungira nyama zikuluzikulu. Ndi pansi chisanu yonyowa zathandiza fluffy.

ubweya Izi si zovuta. Yekha, choncho ankaona kuti kwambiri mtengo ubweya anakudzula. vyschipa luso ndi zodzikongoletsera yambiri ndondomeko, amene kumawonjezera kwambiri mtengo wa ubweya, pamene kupanga makamaka airy ndi kuwala. Pepala ntchito kokha zikopa lonse la nyama. Pakuti aliyense osiyanasiyana item mtundu amusankha payekha. Nthawi zina zikhoza kutenga chaka. Ngakhale chifukwa cha ichi, icho chimakhala chithunzi chenicheni cha zogwirizana mtundu gamut, iridescent zachilengedwe mithunzi ku kuwala mdima.
