lauoho hau (Exidiopsis effusa)

:

• hulu hau
• Ua ninini ʻo Telephora
• ʻO Exidiopsis hale
• Ua kahe ka Sebacin

ʻO "Ice hair", i kapa ʻia ʻo "ice wool" a i ʻole "frost beard" (hau lauoho, hulu hau a ʻumiʻumi hau paha) he ʻano hau i hana ʻia ma luna o ka lāʻau make a ʻano like me ka lauoho siliki maikaʻi.

ʻIke ʻia kēia ʻano ma ka ʻĀpana ʻĀkau, ma waena o ka 45th a me 50th parallels, ma nā ululāʻau deciduous. Eia nō naʻe, ʻoi aku ma luna o ka 60th parallel, hiki ke ʻike ʻia kēia hau nani kamahaʻo i kēlā me kēia manawa, inā he ululāʻau kūpono a me ke ʻano "pololei" (ka moʻolelo a ka mea kākau).

Hoʻokumu ʻia ka "Ice hair" ma luna o ka lāʻau popopo maloʻo (nā lāʻau make a me nā lālā o nā ʻano nui) ma kahi mahana ma lalo o ka zero a me ka haʻahaʻa kiʻekiʻe. Ulu lākou ma luna o ka lāʻau, ʻaʻole ma ka ʻili o ka ʻili, a hiki ke ʻike ʻia ma kahi hoʻokahi no kekahi mau makahiki i ka lālani. He 0.02 mm ke anawaena o kēlā me kēia lauoho a hiki i ka 20 knm ka lōʻihi (ʻoiai ʻoi aku ka maʻamau o nā hiʻohiʻona haʻahaʻa, a hiki i 5 knm ka lōʻihi). He palupalu loa nā lauoho, akā, akā naʻe, hiki iā lākou ke wili i loko o "nā nalu" a me nā "curls". Hiki iā lākou ke mālama i ko lākou ʻano no nā hola he nui, a me nā lā. Hōʻike kēia i kekahi mea e pale ana i ka hau mai ka rerystallizing - ke kaʻina hana o ka hoʻohuli ʻana i nā kristal hau liʻiliʻi i mau mea nui, ʻo ia ka mea maʻamau loa i nā mahana ma lalo o ka ʻole.

Ua wehewehe mua ʻia kēia mea kupaianaha i ka makahiki 1918 e ka German geophysicist a me ka meteorologist, ka mea nāna i hana i ke kumumanaʻo o ka continental drift Alfred Wegener. Ua manaʻo ʻo ia ʻo kekahi ʻano haʻo ke kumu. I ka makahiki 2015, ua hōʻoia ka poʻe ʻepekema Kelemania a me Swiss ʻo kēia fungus ʻo Exidiopsis effusa, he lālā o ka ʻohana Auriculariaceae. ʻAʻole maopopo loa ke ʻano o ka hau e hoʻohāinu ai i ka hau ma kēia ʻano, akā manaʻo ʻia ua hana ia i kekahi ʻano o ka recrystallization inhibitor, e like me kāna hana i ka antifreeze protein. I kēlā me kēia hihia, aia kēia haʻuki i nā lāʻau āpau i ulu ai ka "hau hau", a ma ka hapalua o nā hihia ʻo ia wale nō ka ʻano i ʻike ʻia, a ʻo kona hoʻopau ʻana me nā fungicides a i ʻole ka ʻike ʻana i ka wela kiʻekiʻe i alakaʻi i ka ʻoiaʻiʻo " ʻaʻole i ʻike hou ʻia ka lauoho hau.

ʻO ka halo ponoʻī he maʻalahi loa, a inā ʻaʻole no ka lauoho ʻano ʻē o ka hau, ʻaʻole lākou i hoʻolohe. Eia naʻe, i ke kau mahana ʻaʻole i ʻike ʻia.
