Hoʻolauna i nā mea kolo a me kā lākou mau ʻai

ʻO nā mea kolo he vertebrates koko anuanu e komo pū ana me nā nahesa, nā moʻo, nā koʻokoʻo, a me nā honu. Loaʻa iā lākou kahi kaʻina metabolic kūikawā e hiki ai iā lākou ke ola no nā manawa lōʻihi me ka ʻole o ka meaʻai. ʻAʻole like me nā mammals a me nā manu pono e ʻai pinepine e mālama i ka mahana o ke kino, hiki i nā mea kolo ke hele ʻole me ka ʻai ʻole no nā pule, mahina, a i ʻole mau makahiki. ʻO kēia hiki ke ola me ka ʻole o ka meaʻai ma muli o ka lohi o ka metabolic rate, e hiki ai iā lākou ke mālama i ka ikehu a lawe i nā meaʻai hou aʻe mai ka ʻai pinepine ʻole.

ʻO nā mea kolo nā mea hānai manawaleʻa e ʻai i nā ʻano meaʻai like ʻole, e like me nā iniseti, nā mea kanu, nā mammals liʻiliʻi, a me nā mea kolo ʻē aʻe. ʻO kekahi mau ʻano, e like me nā nahesa, hiki ke hele no nā pule a i ʻole mau mahina me ka ʻai ʻole ma hope o ka ʻai nui. ʻO nā mea ʻē aʻe, e like me nā honu, hiki ke ola no nā mahina me ka ʻole o ka ʻai i ka wā moe. ʻO ka hoʻomaopopo ʻana pehea e ola ai nā mea kolo no ka manawa lōʻihi me ka ʻole o ka meaʻai e pono ai ka hoʻomaopopo ʻana i kā lākou metabolic rate a me nā hoʻolālā mālama mālama ikehu.

Ka helu Metabolic a me ka mālama ʻana i ka ikehu ma nā mea kolo

He haʻahaʻa haʻahaʻa ko nā mea kolo ma mua o nā mammals a me nā manu, e hiki ai iā lākou ke mālama i ka ikehu a ola me ka ʻole o ka meaʻai no ka manawa lōʻihi. ʻO kā lākou metabolism lohi, ʻo ia ka hoʻohana ʻana i ka ikehu liʻiliʻi e mālama i ka mahana o ke kino a me nā hana ʻē aʻe o ke kino. ʻO kēia no ka mea he ectothermic nā mea kolo, ʻo ia hoʻi ke hoʻoponopono ʻia ka mahana o ko lākou kino e ke kaiapuni ma mua o nā kaʻina kūloko. ʻO ka hopena, pono lākou i ka liʻiliʻi o ka ikehu e mālama i ko lākou kino ma mua o nā holoholona endothermic e like me nā mammals a me nā manu.

Ma waho aʻe o kā lākou metabolism lohi, loaʻa i nā mea kolo nā hoʻololi ʻē aʻe e kōkua iā lākou e mālama i ka ikehu. No ka laʻana, hiki iā lākou ke hoʻolohi i kā lākou pae hana i ka wā liʻiliʻi ka meaʻai, e hōʻemi ana i ko lākou pono ikehu. Loaʻa iā lākou kahi ʻōnaehana hoʻoheheʻe kūʻokoʻa e hiki ai iā lākou ke unuhi i nā meaʻai hou aʻe mai ka ʻai pinepine ʻole. ʻO kēia mau hoʻololi, me ko lākou hiki ke hoʻohana i nā waihona momona a me ka hibernate a i ʻole estivate, hiki i nā mea kolo ke ola no nā manawa lōʻihi me ka ʻole o ka ʻai.
