He holoholona ʻano ʻole ka beaver. Kūkulu nā mea ʻē aʻe he nui i nā pūnana a i nā lua paha, akā ua hele a lōʻihi ka mea beaver a lilo i ʻenekini. Mahalo i kā lākou kālena hana 'enekinia a me ka anatomy kūikawā, hiki i kēia mau holoholona ke pale i ka muliwai me kahi wai maoli. Eia kekahi, ʻaʻole kūlike ka muliwai beaver me ka liʻiliʻi o kēia holoholona.
ʻO ka beaver kahi mea kālai lāʻau i hana ʻia e ke kūlohelohe. ʻO kāna mau kui kuiʻoi ʻoi aku he kani a ua kōkua piha ʻia e nā auwau ikaika me nā mākala ikaika. ʻO kēia ka mea e ʻae ai i nā beaver e kua i lalo nā kumu lāʻau, kahi e hoʻokumu ʻia ai nā dam a me nā mea i kapa ʻia ʻo "huts" ma hope.
Pono ka ikaika a me ka pono o ka beaver e haʻi ʻokoʻa: hiki i kēia holoholona ke neʻe i 10 mau manawa ma mua o kona kaumaha pono i loko o hoʻokahi lā, e like me 220-230 kg. Hiki i hoʻokahi beaver ke kīkē i lalo o ʻelua haneli mau lāʻau i kēlā me kēia makahiki.
Inā lawa nā kumulāʻau o ka beaver, hiki iā lākou ke hoʻonui i ko lākou dam i mau mika i kēlā me kēia lā.
ʻO ka hopena o kēlā ʻano ʻino e hana ana i nā ʻāina i nā loli nui. Eia naʻe, ʻaʻole kaupalena ʻia nā beaver i ke kamana wale nō. Lawe pū lākou i nā hana ma lalo o ka wai e ʻohiʻohi mau nei i nā ʻāpana o nā pōhaku, nā pōhaku a me ka ʻeli ʻana i ka silt: ma kēia ʻano e hoʻāʻo nei lākou e hana i ka wai i loko o ka hohonu o ka wai wai wai. No laila, ʻoi aku ka ākea ka noho ʻana o nā beaver.
He aha ka muliwai beaver nui loa?
I ka mālamalama o ka manaʻo o nā beaver i kahi ʻano ʻokoʻa e kūkulu a me kā lākou hana, he maʻalahi ke koho ma lalo o kekahi mau kūlana ʻaʻole hiki iā lākou ke hoʻololi hou i ke ʻano o ka wahi, akā kūkulu pū kekahi i kahi ʻano gigantic.
ʻO kēia ka mea i hana ʻia ma nā panalāʻau o ka Buffalo National Park (Kanada). Noho nā beaver e noho ana i laila i ke kūkulu ʻana i ka wai kūloko i ka makahiki 70 o ke kenekulia XX. A mai ia manawa mai, ʻaʻohe manaʻo ʻē aʻe i ka pau ʻana o kā lākou "kūkulu wā lōʻihi". A ʻo kahi hopena, ulu mau kona ana, a i ke ana ʻana o ka wai wai beaver, ʻo kona lōʻihi ma kahi o 850 mau mika. ʻO kēia ka nui o nā pā soccer ʻewalu i hui pū ʻia.
Hiki ke ʻike ʻia mai kahi ākea, a i mea e hiki ai ke koho i kona nui ma ka honua, pono ʻoe e kōkua i ke kōkua o nā mea hana kūikawā, e like me ka helikopa. I mea e ʻike maikaʻi ai i ka wai wai beaver nunui, ua kūkulu ka hoʻokele o ka paka i kahi flyover kūikawā.
Mai ia manawa, ua manaʻo ʻia kēia wai wai ka nui loa ma ka honua, ʻoiai aia kekahi mau hōʻike e hōʻike ana i nā hale ʻoi aku ka nui ma mua o hoʻokahi kilomita ka lōʻihi.
A ʻo nā wai wai beaver maʻamau, ʻo ko lākou lōʻihi mai kahi ʻumi haʻahaʻa a hiki i kahi haneli mau mika. Ua kūkulu ʻia nā moʻolelo ma mua e nā beaver ma ka muliwai ʻo Jefferson a ma kahi o 150 mau mika ka lōʻihi.
I ka manawa a pehea e ʻike ʻia ai ka wai wai beaver nui loa
ʻO ka hale i hōʻike ʻia aʻe nei i noho kākau ʻole ʻia no kahi o kanahā mau makahiki. I kēlā me kēia hihia, ʻo nā limahana o ka Buffalo Park, e ʻike nei e kūkulu ana nā beaver i ka pā, ʻaʻole lākou i ʻike e pili ana i ka nui maoli. A ʻo ke ʻano o ke kūkulu ʻia ʻana o ka dam i nā makahiki 70 ua ʻike ʻia i nā kiʻi i lawe ʻia i kēlā manawa e ka ukali.
Ua ʻike ʻia e kahi malihini loa e hoʻohana ana i ka palapala ʻāina ʻo Google Earth. He mea kiki ʻole nō hoʻi ka loaʻa ʻana, ʻoiai ke kālailai maoli nei ka mea noiʻi i ka hoʻoheheʻe ʻana o ka permafrost ma nā panalāʻau o North Canada.
He mea ʻē paha i kekahi poʻe ʻaʻole i ʻike ʻia kahi wai nui e like me ka lōʻihi, akā pono e hoʻomaopopo ʻia he nui loa ka ʻāina ʻo Buffalo Park a ʻoi aku i ka wahi o Kuikilana. Ma waho aʻe o kēia, aia ka dam beaver, me kāna poʻe kūkulu hale, aia ia i kahi wahi hiki ʻole ke kiʻi ʻia e ka hapa nui o ka poʻe ma laila.
He aha nā mea kūkulu o ka wai wai beaver nui loa i kēia manawa?
Me he mea lā ua hoʻokū iki ka poʻe beaver i ke kūkulu ʻana o kā lākou lako nui a ke hoʻonui nei i nā wai ʻelua ʻē aʻe, ʻaʻole nui loa. Aia nā wai wai ʻelua ma "ka ʻaoʻao" o ka mea nui, a inā e hana nā beaver me lākou me ka ʻiʻina like e like me kēia manawa, a laila ma hope o kekahi mau makahiki e hui pū nā waʻa, e lilo ana ma mua o kahi kūkulu mile.
Pono eʻae ʻia ʻaʻohe holoholona ʻē aʻe e hoʻololi i ka ʻāina e like me ka beaver. ʻO ka poʻe wale nō ka hiki ke hoʻokō i nā hopena i ʻike ʻia ma kēia ʻaoʻao. ʻO ia ke kumu i mālama mau ai ka poʻe ʻōiwi ʻAmelika i nā beaver me ka mahalo kūikawā a kapa iā lākou ʻo "ka poʻe liʻiliʻi."
Hoʻopilikia a maikaʻi paha nā waihona wai beaver?
E like me ka mea i hoʻololi ʻia, he kuleana koʻikoʻi nā dam beaver ʻaʻole wale i ke ola o kēia mau koʻokoʻo, akā i nā manu neʻe.
Eia kekahi, hōʻike ʻia nā noiʻi ʻepekema he mea nui lākou no nā manu neʻe, a ʻo ka nui o ia mau mea e hilinaʻi nui ʻia i nā dam. I loko nō o ka nui o nā kumulāʻau e kūkulu i nā pā, pono maikaʻi ka hopena o ka hana beaver i ke kaiapuni.
ʻO nā manu, nā kahawai a me nā kaiaolaola muliwai e pōmaikaʻi nui ʻia mai nā wai wai. Mahalo i nā pani wai, ʻike ʻia nā wahi paʻa hou, a puni kahi e ulu ai nā mānoanoa hou, e kōkua ana i ka hana hou ʻana o nā manu.
Aia kekahi kumu e manaʻoʻiʻo ai ke emi mau nei ka nui o nā songbird migratory ma muli o ka nele o nā dam beaver. I kēlā me kēia hihia, kūkulu ka nui o nā ʻohana o nā beaver i kā lākou kūkulu i kahi wahi, ʻo ka nui a me ka lehulehu ka heluna o nā songbirds i kēia wahi. Eia kekahi, ua ʻike nui ʻia kēia hopena i nā wahi semi-arid.
Wahi a nā kānaka ʻepekema, ua hoʻoliʻiliʻi loa nā ʻōnaehana o ka muliwai. Hōʻike ka ʻikepili e pili ana i ke koʻikoʻi o nā wai wai beaver no kā lākou hoʻihoʻi hou ʻana inā e ʻae ʻia nā beaver e alakaʻi i ko lākou ʻano kūlohelohe, e hoʻihoʻi nui kēia i ke kūlohelohe a hoʻonui i ka heluna manu.
Eia nō naʻe, noʻonoʻo ka poʻe i nā beaver he pests, mai ka kua ʻana i nā kumu lāʻau a me nā wahi kahe pinepine a nā kamaʻāina kūloko. A inā i ka hoʻomaka o ka miliona o nā beaver i noho ai i nā panalāʻau o ʻAmelika Hui Pū ʻIa, a laila ma hope o ka hoʻomaka ʻana o ka huli holoholona lehulehu ua aneane pau lākou i ka hoʻopau ʻia, a nalowale nā wai wai pia i aneane ma nā wahi āpau. Wahi a nā zoologists a me nā kālaihonua, he ʻano ʻenekinia kaiāulu nā beaver. A i ka mālamalama o ka hiki ke hele mai me nā maloʻo hou me ka loli hou o ke aniau, hiki i nā beaver ke lilo i mea nui e hakakā ai iā lākou a me nā ʻāina neoneo.
