I ka mahele subtropical, ulu nā ululāʻau like ʻole, i maʻa mau ma ka hema a me ka ʻākau hemispheres o ka honua. ʻO kekahi o nā ʻano he ulu lāʻau maloʻo maloʻo maloʻo. He wahi maloo ko kēia wahi kūlohelohe, no ka mea ua i ka hoʻoilo, a ʻokoʻa ka nui mai 500 a 1000 milima i kēlā me kēia makahiki. ʻO nā kauwela ma aneʻi he maloʻo a wela hoʻi, a i ka hoʻoilo ʻaʻohe hua hau. No nā ululāʻau paʻakikī, ʻano kēia nā hiʻohiʻona aʻe:
- ʻo ke kumu o ka ululāʻau nā lāʻau paʻakikī a me nā lāʻau liʻiliʻi;
- Hoʻokahi papa o ke kolo;
- hana nā lāʻau i nā kalaunu ākea;
- ulu nā ulu lāʻau nui mau loa i ka underbrush;
- he lāʻau ikaika nā lāʻau i kēia mau ulu lāʻau, a hoʻomaka ko lākou mau lālā kokoke i ka pae honua.
Flora o nā ululāʻau paʻakikī
ʻO nā ululāʻau maloʻo kauwela me nā lāʻau pahele paʻakikī i maʻa mau i nā wahi like ʻole o ka honua. Ma ʻEulopa, loaʻa lākou i ka moku Mediterranean, a ma aneʻi he lāʻau ʻoka a me ka paina. Ma nā kahakai o ka Moana ʻAkelanika, lilo ka flora i mea like ʻole, e like me nā ʻoka ʻokoʻa e kū nei ma aneʻi - cork, walloon, a me marmot. ʻO kahi pae ma lalo o kahi ulu lāʻau ʻo ia nā kumu pistachio a me ka myrtle, nā lāʻau strawberry a me nā ʻoliva, boxwood a me nā laurel hanohano, nā junipers, a me nā ʻano ulu lāʻau a me nā kumulāʻau.
Loaʻa nā mea kanu āpau i kēia ʻano ulu lāʻau i nā adaptation kūikawā e kū ai i ka wela. Loaʻa i nā lau o kekahi kumulāʻau kahi uhi waxy, he spine a me nā wana kā kekahi, a ʻo kekahi he ʻāpana manoanoa loa. Aia ka liʻiliʻi o ka evaporation i loko o ka ululāʻau deciduous ma mua o nā kaiaolaolaola ulu lāʻau ʻē aʻe, ma muli paha o ka loaʻa o nā aila o kēia mau lāʻau i ka nui o nā aila pono.
Inā ʻike ʻia ka hou ma kekahi mau wahi, a laila hiki i ka maquis, nā mānoanoa o nā laʻalāʻau mau ke ulu ma aneʻi. Loaʻa iā lākou, me ka hoʻohui i nā ʻano i haʻi ʻia ma luna, heather a me gorse, rosemary a me cistus. Ma waena o nā lianas, ulu ka asparagus prickly. ʻO thyme a me lavender, a me nā mea kanu ʻē aʻe e ulu ana i ka mauʻu mauʻu. ʻO nā legume, heather rosaceous a me nā mea kanu xerophilous e ulu i nā ululāʻau o ʻAmelika Hema.
Huahana
No laila, noho nā ululāʻau paʻakikī i kahi ma ka ʻāpana subtropical. ʻAno ʻokoʻa ke kaiaolaola o kēia ʻano nahele, ma muli o nā hiʻohiʻona o ke anilā kahi i hoʻopili ai ka flora i kahi mea e hiki ai iā lākou ke noho me ka liʻiliʻi o ka wai i nā kūlana wela.
