Tundra yakhala ndi nyengo yovuta, koma ndiwofatsa pang'ono kuposa dera la Arctic Ocean. Apa mitsinje ikuyenda, pali nyanja ndi madambo momwe mumapezeka nsomba ndi nyama zam'madzi. Mbalame zimauluka pamwamba pazitali, chisa apa ndi apo. Kumeneku amakhala okha m'nyengo yotentha, ndipo ikayamba kuzizira kwambiri nthawi yophukira, amathawira kumadera otentha.
Mitundu ina yazinyama idazolowera chisanu, chisanu komanso nyengo yovuta yomwe ikupezeka kuno. M'dera lachilengedwe lino, mpikisano ndikulimbana kuti mupulumuke kumamvekera makamaka. Kuti nyama zipulumuke, zakhala ndi luso ili:
- chipiriro;
- kudzikundikira kwa mafuta ochepa;
- tsitsi lalitali ndi nthenga;
- kugwiritsa ntchito mphamvu mwanzeru;
- malo ena osankhira;
- mapangidwe chakudya chapadera.
Mbalame za Tundra
Mbalame zambirimbiri zikubweretsa phokoso m'derali. Pamtundawu, pali ma pollover akadzidzi ndi akadzidzi, ma gulls ndi ma tern, ma guillemots ndi chipale chofewa, ma eider ndi ptarmigan, mapulani a Lapland ndi mapaipi ofiyira ofiira. M'nyengo yachilimwe-chilimwe, mbalame zimauluka pano kuchokera kumayiko ofunda, zimakonza magulu akuluakulu a mbalame, zimamanga zisa, zimayakira mazira ndikulera anapiye awo. Pofika nyengo yozizira, ayenera kuphunzitsa ana kuwuluka, kuti pambuyo pake onse awuluke kumwera limodzi. Mitundu ina (akadzidzi ndi ma partges) amakhala mchimangachi chaka chonse, popeza azolowera kukhala pakati pa ayezi.

Anthu okhala m'madzi ndi mitsinje
Omwe amakhala m'madamu ndi nsomba. Mitundu yotsatirayi imapezeka mumitsinje, nyanja, madambo ndi nyanja za Russian tundra:

Nsomba zoyera
Salimoni
Vendace
Dallia
Madamu ali ndi plankton, mollusks amakhala. Nthawi zina ma walrus ndi zisindikizo zochokera kumalo oyandikana nawo zimangoyendayenda m'dera lamadzi la tundra.
Zinyama
Ankhandwe akum'mwera kwa Arctic, mphalapala, ndulu, ndi mimbulu yakumtunda ndiomwe amakhala m'chigawochi. Nyama izi zimasinthidwa kukhala moyo kumadera ozizira. Kuti apulumuke, amayenera kuyenda nthawi zonse ndikufunafuna chakudya chawo. Komanso apa nthawi zina mumatha kuwona zimbalangondo zakumtunda, nkhandwe, nkhosa zazikulu ndi zoweta, ma weasels, ma ermine ndi minks.

Chifukwa chake, dziko lanyama lodabwitsa lidapangidwa mu tundra. Moyo wa oimira zinyama zonse pano umadalira nyengo komanso kuthekera kwawo kupulumuka, chifukwa chake mitundu yapadera komanso yosangalatsa yasonkhana mdera lino. Ena mwa iwo amakhala osati mumtunda wamtunda, komanso m'madera ozungulira.
