Nā laʻana o nā holoholona poikilothermic

ʻO ka holoholona poikilothermic (ʻoi aku nei i kapa ʻia ʻo 'ectotherms') nā mea e hoʻoponopono i kā lākou mahana mai ka mahana wela.

Hana ʻia kēia no ka mea ʻaʻohe o lākou ʻano o nā meaola ʻē aʻe, kahi e hiki ai ke kaohi i ka mahana o ko lākou kino e ka hoʻoulu ʻana i ka wela: ʻo kēia ke kumu i kapa pinepine ʻia ai kēia ʻano holoholona he "holoholona anuanu". ʻO nā holoholona ʻaʻole poikilotherms nā 'homeotherms' (a i ʻole 'endotherms'), kahi e kū ai nā māmela āpau.

Nā ʻano a me nā hana

Ma ka laulā, hoʻololi ka poikilotherms liʻiliʻi loa i ka mahana o ka lumi, akā aia kekahi o lākou e hiki ke kaupalena i nā mahana wela e pili ana i ka hana wela, a laila hoʻololi lākou i ka hopena pōkole o ka loli wela.

I kēia mau lā ua ʻike kekahi mau ʻepekema i ka loli ʻana o kēlā me kēia lā i ka mahana wela e hoʻololi ai i ka ʻike o nā laha i ka hoʻomehana ʻana i hopena ʻia e ke aniau, e ka hoʻohaʻahaʻa ʻana i nā palena o ka palekana wela.

Nā mea maikaʻi a me nā mea maikaʻi ʻole

ʻOiai nā holoholona endothermic e hoʻoulu i ka wela mai ka ikehu i loko o ka meaʻai, ectotherms ʻaʻole pono lākou e hānai i kēlā me kēia lā a hiki paha iā lākou ke hele i mau mahina me ka hānai ʻole.

Hāʻawi kēia iā lākou i kahi pōmaikaʻi, i offset ʻia e ka ʻoiaʻiʻo ʻaʻole hiki iā lākou ke noho i nā wahi me nā mahana wela loa, no ka mea, hilinaʻi nui lākou i nā hoʻololi o ka nohona: endotherms, ma ka ʻaoʻao ʻē aʻe, hiki ke noho i nā wahi anuanu a mehana.

Nā hoʻonohonoho Poikilotherm

E like me ka ectotherms pili ka lula o ka mahana i ka hiki ke kaohi i ka hoʻololi o ka wela me ke kaiapuni, he mea maʻamau ka pono e hana ʻia kekahi no ka thermoregulation. Māhele ʻia kēia i ʻelua mau hui:

ʻO ka hoʻoponopono hoʻoponopono hana ʻO lākou nā hoʻololi i ka lawena e ʻimi nei i nā wahi i ke kaiapuni kahi e ʻoluʻolu ai ka mahana i nā hana. Aia kekahi mau ʻano i kapa ʻia ʻo euthermic, i hiki ke ola i waena o nā pā o ka mahana o ke kino.
ʻO ka hoʻoponopono physiological ʻO lākou nā mea e hoʻololi i nā mele metabolic i ka mahana e kū nei, i kahi ala e hoʻololi ʻole ai ka ikaika o ka metabolism. Hana kēia ʻano holoholona i ka uku pāmahana e ʻae iā lākou e loaʻa i ka pae o ka hana i nā wahi me nā ʻano like ʻole: like lākou me nā endotherms, e hoʻoponopono pololei nei i kā lākou ʻōnaehana me ka nānā ʻole i ka mahana o ke kino.

Nā ʻokoʻa

Aia kekahi mau hihia o nā holoholona ʻaʻole ectothermic, akā he ʻano like ko lākou.

ʻO ka endothermy āpana, no ka laʻana, ke hana ia ke hoʻololi ke ana wela o ka puʻuwai a me nā gills me nā loli o ka mahana o ke kaiapuni, e like me ka hopena o kekahi mau pūʻulu iʻa.
ʻO ka facotherative endothermyMa ka lima ʻē aʻe, hana pinepine ia i nā mea kolo i hiki ke hana i ka wela me ka haʻalulu o ko lākou mauʻiʻo, e hoʻokiʻekiʻe nei i ko lākou kino no kekahi manawa.
