ʻO nā holoholona koko wela a anuanu hoʻi

• Nā laʻana o nā holoholona wela
• Nā laʻana o nā holoholona koko anu

Ua hiki i nā noiʻi ʻana i ka thermo-physiology ke hoʻoholo ʻaʻole wale nō ʻelua mau ʻāpana (nā holoholona koko anuanu a me nā holoholona wela) no nā mea i hoʻohana ʻole ʻia nā manaʻo ʻelua.

Eia naʻe, ua hoʻohana ʻia nā ʻokoʻa ʻelua a hoʻomau e hoʻohana nui ʻia, ʻo ia ke kumu e pono ai kā lākou wehewehe.

ʻO kaholoholona hānai mehana ʻO lākou ka mea hiki ke mālama i kahi mahana mau o ke kino e nānā me ka nānā ʻole i nā ʻano pae o ke kaiapuni. Mālama ka hapa nui o nā mammal i ke ana wela o ke kino ma waena o 34º a 38º.

Hiki paha iā lākou ke loli i ko lākou kino mahana, akā he liʻiliʻi kēia. I nā huaʻōlelo ʻē aʻe, ua ʻōlelo ʻia kēia mau holoholona he homeostasis wela. ʻO nā holoholona koko wela kekahi i kapa ʻia he endotherms.

Nā laʻana o nā holoholona wela

Nā ʻano thermoregulation

ʻEkolu mau ʻano ʻokoʻa o ka thermoregulation nā holoholona mehana.

• Kahikina. Hiki i kekahi mau holoholona pumehana ke hana i ka wela o loko i ko lākou kino ponoʻī. ʻike ʻia ka hōʻike o ka mea ma hope o ka haʻalulu ʻana, panting a puhi ʻana paha i ka momona.
• Homeothermy. Ua ʻike ʻia kēia ʻano he holoholona wela, ʻoiai ʻo ia kekahi o nā ʻaoʻao ʻekolu e hiki i kēia ʻano holoholona ke hōʻike. ʻO ia ke ʻano o ka mālama ʻana i ka mahana o ke kino mau a ʻoi aku ke kiʻekiʻe ma mua o ka mahana o ka mahana.
• ʻO Tachymetabolism. Mālama kēia mau holoholona i kahi kiʻekiʻe o ka metabolism i ka hoʻomaha.I nā huaʻōlelo ʻē aʻe, he holoholona lākou e mālama i ka mahana o ke kino ma hope o ka hoʻomaha ʻana ma muli o kēia, mālama lākou i ka wela o ko lākou kino.

ʻOiai ʻo ka hapa nui o nā māmela a me nā manu, he holoholona mehana koko, hōʻike i nā ʻano ʻekolu o ka thermoregulation, i kekahi mau hihia ua ʻike ʻia ʻaʻole paha lākou e hōʻike i nā mea ʻekolu. No laila, i ka hihia o nā ʻōpeʻapeʻa a i ʻole kekahi manu liʻiliʻi, ʻelua paha o lākou i ʻekolu mau ʻano. Eia nō naʻe, ua kapa ʻia lākou he mau holoholona wela.

ʻOiai hoʻohana ʻia ka huaʻōlelo i kēia manawa i ka ʻike ʻepekema mai ka hoʻohana ʻia ʻana o nā holoholona ectothermic, pili kēia hoʻokaʻina i kēlā mau holoholona i kaohi i ko lākou kino wela e pili ana i ka mahana o ke kaiapuni.

ʻO ka maʻamau, noho nā holoholona anu-anuanu i nā anilā wela loa a ʻaʻole ʻike pinepine ʻia lākou i nā anuanu anuanu. Eia nō naʻe, he ʻē aʻe paha.

Nā ʻano thermoregulation

• ʻO Ectothermy. Hiki ke noʻonoʻo ʻia nā holoholona anuanu āpau i nā holoholona ectothermic mai ka wā e hoʻoponopono i ko lākou kino wela e pili ana i ka mahana o ka nohona.
• Poikilothermia. He holoholona lākou e hoʻoponopono i ka mahana o ko lākou kino ma ka hoʻohālikelike ʻana iā ia i ko lākou kaiapuni koke.
• ʻO Bradymetabolism. ʻO lākou nā holoholona e loli i ka wikiwiki o kā lākou metabolism e hoʻoponopono i ka mahana o ko lākou kino ma muli o ka meaʻai e kū nei a me ka mahana wela.

E like me nā holoholona mehana koko, ʻaʻole nā ​​holoholona anuanu ke anuanu o ka thermoregulation.

He aha nā holoholona ovoviviparous?

Ma hope o ke kau ʻana i ʻelua holoholona, ​​hoʻokahi koko-anuanu a me kekahi-mehana-koko, ma lalo o ke kukui infrared, hōʻike ʻia ka holoholona koko pumehana i kona kukui ponoʻī, ʻo ia hoʻi, kona wela ponoʻī. I ka hoʻohālikelike ʻana, noho mau ka holoholona anu-anuanu i ke kala.

No kēia kumu, pono i nā holoholona anuanu ke noho i nā wahi mehana a hoʻomehana i ko lākou kino ma ka lā ʻana i ka lā a i ʻole ka hoʻohana ʻana i nā ʻano kūwaho e hāpai i ka mahana o ke kino.
