Chimodzimodzi Nkhalango kukopa asayansi? yankho zosiyanasiyana yaikulu kwambiri zamoyo. Chotero, inu mukhoza kuwerenga mitundu ochepa a mitengo ya m'nkhalango za Nyengo m'dera la mahekitala wina. Mwachitsanzo, paini nkhalango (makamaka paini), birch munda, etc. onse mosiyana kwambiri poyerekezera rainforest ndi -. Kudera lomwelo oposa 80 mitundu azikhala. m'zinthu moyo awo kwambiri imachitika kuti ngakhale ofufuza choyenera rainforest kuzindikira kuti mumvetse kwathunthu ubale onse adakali kutali kwambiri. Kumene, mmodzi yekha zosiyanasiyana mbewu si wotopa. nkhalango Awa kunyumba zosiyanasiyana arthropods, zokwawa zam'madzi. Pambuyo chochuluka zakudya zomera zipangitsa zosiyanasiyana herbivores. Pano pali chitsanzo: ngati inu kutenga malo a kunyanja ya nkhalango ndi mbali ya lalikulu 10 mamita lalikulu. Km, ndiye n'zotheka kuwerenga mitundu yoposa 100 agulugufe, 120 mitundu ya nyama ndi osachepera 400 - mbalame.

Mpweya gawo imene imagwera mu mapapo athu ndi aliyense mpweya, ndi mbali ya mpweya wa, "kubadwa" mu kunyanja "mapapo wobiriwira" dziko lapansi. Kodi kuwateteza ku cuttings? N'zoona kugwira zitsanzo ndi misonkhano - ndi operewera, koma nzeru wakale ananenetsa kuti chabe wopita imayamba ndi kuchita wochepa. Ndipo mu nkhalango: kulemekeza chikhalidwe mu malo awo okhala - ndi sitepe ochepa.
