Kutha ndi nyengo yosintha kuchokera nyengo yotentha mpaka yozizira. Pakadali pano, kusintha kwakukulu kumachitika m'chilengedwe: kutentha kwa mpweya kumatsika ndipo masana amasintha, masamba amagwa ndipo udzu umasanduka wachikaso, mbalame zosuntha ndi mileme zimasamukira, tizilombo ndi nyama zikukonzekera nyengo yozizira. Mitundu ya zinyama zomwe zimakhala m'malo otentha m'nyengo yozizira zimachita mosiyana:
- nsomba zimalowa mkati mwa maenje a chisanu;
- nyerere zimatuluka m'madzi kupita kumtunda, zikulumikizana pansi pamasamba, pansi kapena pansi;
- achule ndi achule amapanga malo awo osanjikiza;
- tizilombo timabisala m'mapanga a mitengo, timabisala pansi pa khungwa;
- mitundu ina ya agulugufe amawulukira kumadera otentha.
Chochititsa chidwi kwambiri ndi momwe nyama zimakonzekera nyengo yachisanu.
Hibernation ndi kusintha kwa utoto
Kutengera mitundu, nyama zosiyanasiyana zimakonzekera nyengo yozizira m'njira yawoyawo. Ena mwa iwo amabisala:
- Zimbalangondo;
- ziphuphu;
- mbira;
- nyumba yogona;
- ziphuphu;
- ziphuphu;
- mileme;
- chipmunks, ndi zina.
Nyama zambiri zimasintha mtundu m'nyengo yozizira. Chifukwa chake ma ermines, tundra partridges, reindeer, hares ndi nkhandwe zaku arctic zimasanduka zoyera nthawi yozizira, chifukwa chake zimaphatikizana ndi malo, omwe amawalola kubisalira adani. Nthawi zina zimachitika kuti zamoyo zogwirizana sizisintha mtundu chimodzimodzi. Zimadaliranso ndi kutalika kwa malo. Iwo ndi oimira omwewo amatha kusintha utoto m'njira zosiyanasiyana, ngati kusintha kwa nyengo ndi malo okhala mdera linalake likufuna.
Malo osungira zakudya m'nyengo yozizira
Mitundu yambiri ya nyama imasunga chakudya m'nyengo yozizira. Mbewa ndi ma hamsters, ma voles ndi makoswe ena amakolola mbewu. Agologolo amatola bowa, zipatso ndi mtedza. Chipmunks amasunga mtedza wa paini ndi mbewu m'nyengo yozizira. Makoswe ngati zitsamba zosungira udzu m'nyengo yozizira, momwe zitsamba zingapo zimasonkhanitsidwa ndikudyetsedwa bwino.
Nyama zodya nyama zimaperekanso chakudya m'nyengo yozizira. Zinyama ndi ma weasel amatolera mbewa khumi ndi ziwiri kapena ziwiri m'mayenje. Zipangizo zakuda zimasunga achule ambiri. Pofuna kudya, mink amadzipangira ma kilogalamu angapo a nsomba zosiyanasiyana. Zimbalangondo, mimbulu ndi ma martens amabisa chakudya chawo munthambi zamitengo, m'miyala ndi m'mabowo, kutengera malo awo ozizira.
Oyimira onse anyama akukonzekera kuyambika kwa chisanu mu kugwa. Ena amadzikundikira mafuta ndikugona tulo totalikirapo, ena amasunga chakudya m'mayenje, ndipo ena amasintha nyengo yozizira kukhala yotentha komanso yabwino. Mitundu iliyonse yazinyama ili ndi zosintha zake zomwe zimawalola kuti zizolowere zovuta ndikupulumuka.
