Zamkati
Njovu kapena njovu ndizinyama zomwe zimayikidwa mu dongosolo la Proboscidea, ngakhale kuti m'mbuyomu anali m'gulu la Pachyderms. Ndiwo nyama zazikulu kwambiri zapamtunda zomwe zilipo masiku ano, zomwe zimadziwika kuti ndizanzeru kwambiri. Mitundu iwiri ikudziwika pano, tikulankhula za njovu zaku Africa ndi njovu zaku Asia.
nyama izi kukhala nthawi yayitali, makamaka chifukwa chakuti alibe zilombo zolusa. Komabe, mosiyana ndi zomwe zimachitika ndi mitundu ina ya nyama, mu ukapolo amachepetsa nthawi yawo yopitilira theka, zomwe zimadetsa nkhawa kuteteza kwa mitunduyo.
Munkhaniyi ya Animal Katswiri mudzatha kudziwa njovu imakhala nthawi yayitali bwanji, komanso zifukwa zingapo zoopsa zomwe zimachepetsa kutalika kwa moyo wa nyama zazikuluzikuluzi.
moyo wa njovu
Inu Njovu ndi nyama zomwe zimakhala zaka zambiri, m'malo awo achilengedwe amatha kukhala zaka 40 mpaka 60. Umboni wapezeka kuti zikusonyeza kuti mitundu ina yaku Kenya mwina idakhalako mpaka zaka 90.
Kutalika komwe njovu zitha kukhala nako ndizosintha zomwe zimasintha kutengera dziko lomwe nyama imakhalamo komanso malo omwe amapezeka, monga nyama iliyonse. Nyama izi zilibe adani achilengedwe, kupatula munthu, zomwe nthawi zina zimapangitsa kuti njovu ikwaniritse zaka 35.
Chimodzi mwazinthu zomwe zimadetsa nkhawa malo otetezera amtunduwu ndikuti njovu zomwe zimagwidwa zimachepetsa moyo wawo mopambanitsa. Malingana ngati njovu zimakhala m'malo abwinobwino ndikusowa nyama zakutchire, zili 19 mpaka 20 wazaka mulungu. Zonsezi zimachitika mosiyana ndi mitundu yambiri yomwe, yomwe ili mu ukapolo, imawonjezera zaka zomwe amakhala ndi moyo.
Zinthu zomwe zimachepetsa moyo wa njovu
Chimodzi mwazinthu zazikulu kwambiri zolepheretsa nyama zazikuluzikulu kukhala ndi moyo mpaka zaka 50 ndi Mwamunayo. Kusaka mopitirira muyeso, chifukwa cha malonda aminyanga ya njovu, ndi imodzi mwamadani akuluakulu a njovu, zomwe zimachepetsa kwambiri moyo wa nyama izi.
China chomwe chimalepheretsa njovu kukhala ndi moyo wautali ndichoti kuyambira zaka 40 mano ake amatha, zomwe zimawalepheretsa kudya mwachizolowezi motero pamapeto pake amafa. Akangogwiritsa ntchito mano awo omalizira, imfa imapeŵeka.
Kuphatikiza apo pali zinthu zina zathanzi zomwe zimalepheretsa njovu kukhala ndi moyo wautali, mwachitsanzo nyamakazi ndi mavuto am'mitsempha, zonse zomwe zimakhudzana ndi kukula kwake ndi kulemera kwake. Mu ukapolo, chiyembekezo cha moyo chimachepetsedwa kupitirira theka, chifukwa cha kupsinjika, kusachita masewera olimbitsa thupi komanso kunenepa kwambiri.
Chidwi chokhudza moyo wa njovu
- Njovu zazing'ono zomwe zimabereka asanakwanitse zaka 19 zimawonjezera mwayi wawo wokhala ndi moyo wautali.
- Njovu zikakalamba kwambiri ndipo zatsala pang'ono kufa, zimayang'ana dziwe lamadzi kuti zizikhalabe mpaka mtima wawo utasiya kugunda.
- Nkhani yolembedwa ya njovu yakale ya nkhaniyi ndi ya Lin Wang, njovu yomwe imagwiritsidwa ntchito ndi Chinese Expeditionary Forces. Ali mu ukapolo, nyama iyi idafika modabwitsa 86 wazaka.
Kodi mumadziwa kuti njovu ndi imodzi mwazisanu zazikulu mu Africa?
Tikulimbikitsanso kuti muwone zolemba zotsatirazi zokhudza njovu:
- njovu imalemera bwanji
- kudyetsa njovu
- Kutenga kwa njovu kumatenga nthawi yayitali bwanji
