Biology, joalo ka mahlale a mang, e ruile ka mantsoe a ikhethileng. Lintho tse bonolo tse re potileng le uena hangata li bitsoa mantsoe a sa utloisiseheng. Sehloohong sena re tla bua ka hore na ke bo-mang seoa mme ke mang ya ka bitswang lentsoe leo.

Lentsoe "endemic" le bolelang?

Bofutsana ke mofuta oa semela kapa oa phoofolo o fumanoang sebakeng se fokolang haholo. Mohlala, haeba phoofolo e itseng e lula sebakeng sa lik'hilomithara tse makholo a 'maloa' me e sa fumanehe kae kapa kae Lefatšeng, e atile.

Sebaka se fokolang sa bolulo se bolela ho phela maemong a tlhaho. Liphoofolo tsa mofuta o le mong, tse phelang, ka mohlala, libakeng tsa polokelo ea liphoofolo ho pota lefatše, ha li tlose "sehlooho" sa sebaka se tloaelehileng ho tsoa ho bona ho tsoa lefats'eng le lokolohileng.

Mokhoa oa ho qetela o hlaha joang

Ho thibela libaka tsa liphoofolo le limela ke mochini o rarahaneng oa mabaka a fapaneng. Hangata ke ho arohana ha libaka kapa maemo a leholimo, a thibelang ho hasana ha mefuta sebakeng se pharalletseng. Mohlala o motle oa maemo a joalo ke sehlekehleke.

Ke lihlekehleke tse atisang ho ba le limela le liphoofolo tse atileng haholo tse setseng moo feela eseng kae kapa kae. Kaha ba fihlile sebakeng sena sa mobu lilemong tse ngata tse fetileng, ha ba sa khona ho fallela naheng e kholo. Ho feta moo, maemo sehlekehlekeng sena a lumella phoofolo kapa semela hore se se ke sa phela feela, empa hape le ho fa bana, ho tsoelapele ka mofuta oa sona.

Ho na le mekhoa e fapaneng ea ho fihla sehlekehlekeng - mohlala, peo ea limela tse sa tloaelehang e ka fofa tlase kapa marameng a linonyana. Liphoofolo hangata li fella lihlekehlekeng, ka lebaka la likoluoa ​​tsa tlhaho, mohlala, likhohola tsa sebaka seo ba neng ba phela ho sona pele.

Haeba re bua ka baahi ba metsing, boemo bo loketseng bakeng sa ponahalo ea mofuta o teng ke 'mele o koetsoeng oa metsi. Letša lena, le tlatsitsoeng ka thuso ea liliba ebile ha le na kamano le linoka kapa melapo, hangata le lula le linonyana tse se nang lesapo la mokokotlo kapa litlhapi.

Hape, mabaka a ho hlaha ha li-endemics a kenyelletsa boemo ba leholimo bo ikhethang, ntle le bophelo ba mofuta o itseng bo ke keng ba khoneha. Sena se lebisa ntlheng ea hore libopuoa tse ling li lula feela libakeng tse ling polaneteng ea rona sebakeng se lekantsoeng ke li-kilomitara tse 'maloa.
