Kahakai Komohana, Kahakai maikaʻi loa? ʻAʻole no Starfish.

Na Alex Kirby, Communications Intern, The Ocean Foundation

He maʻi pohihihi e lele mai ana ma ke Komohana Komohana, e waiho ana i ke ala o ka iʻa hōkū make.

Mai Iune 2013, hiki ke ʻike ʻia nā puʻu o nā hōkū kai make me nā lālā kaʻawale ma ke Komohana Komohana, mai Alaska a i Kaleponi Hema. ʻO kēia mau hōkū kai, ʻike ʻia hoʻi ʻo ka iʻa hōkū, e make ana i nā miliona a ʻaʻohe mea i ʻike i ke kumu.

Hiki i ka ma'i hoku kai ke ho'opau i ka heluna kanaka hoku kai i loko o 'elua lā. Hōʻike mua nā hōkū kai i nā hōʻailona o ka loaʻa ʻana o ka maʻi hōʻino ʻia e ka hoku kai ma ka hana ʻana i ka lethargic - hoʻomaka ko lākou mau lima e wili a luhi lākou. A laila hoʻomaka ka ʻeha ma ka ʻāʻī a/a ma waena o nā lima. A laila hāʻule loa nā lima o ka iʻa hōkū, he pane koʻikoʻi maʻamau o nā echinoderms. Eia nō naʻe, ma hope o ka hāʻule ʻana o nā lima he nui, e hoʻomaka ana nā ʻiʻo o kēlā me kēia kanaka e pohō a make ka iʻa hōkū.

ʻO nā luna pāka ma Olympic National Park ma Wakinekona State ka poʻe mua i ʻike i ka hōʻike o ka maʻi i ka makahiki 2013. Ma hope o ka ʻike mua ʻana o kēia mau manakia a me nā ʻepekema limahana, ua hoʻomaka ka poʻe luʻu leʻaleʻa e ʻike i nā hōʻailona o ka maʻi hōʻino ʻana o ka hōkū kai. I ka hoʻomaka ʻana o nā hōʻailona ma nā hōkū kai aia ma ka Pākīpika Komohana Komohana, ʻo ia ka manawa e wehe ai i ka mea pohihihi o kēia maʻi.

ʻO Ian Hewson, he loea microbiology kōkua ma ke Kulanui ʻo Cornell, ʻo ia kekahi o nā loea liʻiliʻi i mākaukau e hana i ka hana o ka ʻike ʻana i kēia maʻi ʻike ʻole. Laki wau i hiki iaʻu ke kamaʻilio me Hewson, ʻo ia ka mea e noiʻi nei i ka maʻi hōʻino ʻia o ka hōkū kai. ʻO ka ʻike kūʻokoʻa o Hewson i ka ʻokoʻa microbial a me nā pathogens, ʻo ia ke kanaka pono e kuhikuhi i kēia maʻi pohihihi e pili ana i 20 mau ʻano iʻa hōkū.

Ma hope o ka loaʻa ʻana o ka hāʻawi kālā hoʻokahi makahiki mai ka National Science Foundation ma 2013, ua hana ʻo Hewson me ʻumikūmālima mau keʻena, e like me nā kula hoʻonaʻauao ma ke kahakai Komohana, ʻo Vancouver Aquarium, a me Monterey Bay Aquarium, e hoʻomaka i ka noiʻi ʻana i kēia maʻi. Hāʻawi nā aquarium iā Hewson i kāna ʻike mua: ua hoʻopilikia ka maʻi i ka nui o nā iʻa hōkū i ka hōʻiliʻili ʻana i nā aquarium.

"ʻOiaʻiʻo ke hele mai nei kekahi mea mai waho mai," wahi a Hewson.

ʻO nā keʻena ma ke Komohana Komohana ke kuleana no ka loaʻa ʻana o nā hōʻailona hoku kai ma nā wahi intertidal. Hoʻouna ʻia nā laʻana ma waena o ʻAmelika Hui Pū ʻIa i ka lab o Hewson, aia ma ka pā kula ʻo Cornell. ʻO ka hana a Hewson ka lawe ʻana i kēlā mau laʻana a nānā i ka DNA o nā hōkū kai, bacteria, a me nā maʻi maʻi i loko o lākou.

I kēia manawa, ua ʻike ʻo Hewson i nā hōʻike o nā hui microorganism i nā ʻiʻo hōkū kai maʻi. Ma hope o ka loaʻa ʻana o nā microorganism i loko o nā ʻiʻo, ua paʻakikī iā Hewson ke hoʻokaʻawale i nā microorganisms maoli ke kumu o ka maʻi.

Wahi a Hewson, "ʻo ka mea paʻakikī, ʻaʻole mākou maopopo i ke kumu o ka maʻi a me ka mea e ʻai wale nei i nā hōkū kai ma hope o ka pohō."

ʻOiai e make ana nā hōkū kai ma kahi ʻano like ʻole, ua ʻōlelo ʻo Hewson i ka hopena o kēia maʻi i nā mea ola ʻē aʻe he nui, e like me ke kumu nui o ka ʻai ʻana o nā hōkū kai, ʻo ka iʻa. Me ka nui o nā lālā o ka heluna hōkū kai e make ana i ka maʻi hoʻopau ʻana i ka hoku kai, e emi ana ka ʻai ʻana o ka mussel, e piʻi ai ko lākou heluna kanaka. Hiki i ka i'a ke lawe i ke kaiaola, a alaka'i i ka emi nui o ke olaola.

ʻOiai ʻaʻole i paʻi ʻia ka haʻawina a Hewson, ua haʻi mai ʻo ia iaʻu i kekahi mea nui: “ʻO ka mea a mākou i ʻike ai he nani a me nā microorganisms. ua pili.

E nānā hou me ka moʻomanaʻo o ka Ocean Foundation i ka wā e hiki mai ana no ka moʻolelo hope ma hope o ka paʻi ʻia ʻana o kā Ian Hewson haʻawina!
