Ke hoʻolaha nei i ka 2020 Boyd Lyon Scholar

I kēlā me kēia makahiki, mālama ʻia ka Boyd Lyon Sea Turtle Fund i kahi haʻawina no kahi haumāna biology moana nona ka noiʻi ʻana i nā honu kai. ʻO Alexandra Fireman ka mea lanakila o kēia makahiki. Aia ma lalo kāna hōʻuluʻulu papahana.

ka Pāhana ʻo Jumby Bay Hawksbill (JBHP) ke nānā nei i nā honu kai hawksbill ma Long Island, Antigua mai ka makahiki 1987.

Ua hōʻike ka heluna kanaka hawksbill ma Antigua i ka ulu lōʻihi mai 1987-2015. Akā, ua emi nui ka helu ʻana i nā makahiki i kēia mau makahiki i hala. No laila, pono koke e loiloi i nā kumu o kēia emi ʻana, e like me ka hoʻohaʻahaʻa ʻana o ka noho ʻana. ʻAi ʻo Hawksbills i nā kaiaola ʻākoʻakoʻa a manaʻo ʻia ʻo ia nā ʻano pōhaku kumu no ka mea he hopena ko lākou emi ʻana i nā kaiaola kai. He mea koʻikoʻi ka hoʻomaopopo ʻana i ke kuleana o ka hawksbill i ko lākou kaiapuni no ka mālama ʻana i ko lākou ʻano. A, ʻo nā kaiaola kaiaola ʻākoʻa holoʻokoʻa.

Pono ke aʻo ʻana i ke kaiaola ʻai o kahi ʻano kai lōʻihi e pono ai nā ʻenehana hou.

Ua hoʻohana ʻia ka loiloi isotope paʻa o nā ʻiʻo inert a me ka metabolically active ma waena o ka taxa e hoʻomaopopo i ka ʻai o nā mea ola. I ke ʻano wae, δ¹³C a me δ¹⁵Ua hoʻohana nui ʻia nā waiwai N no ka wānana ʻana i kahi o ka ʻai ʻana a me ka pae trophic o nā mea kūʻai kai. ʻOiai ua hoʻonui ʻia nā noi isotope me nā honu kai, ʻaʻole maʻamau ka haʻawina isotope o nā hawksbills. A, ʻaʻole nui ka ʻike ʻana o ka manawa-series o ka Caribbean hawksbill keratin isotope haku mele mai ka palapala. Hiki i ka waihona o ka mōʻaukala trophic i mālama ʻia i ka carapace keratin ke ala ikaika no ka loiloi ʻana i ka hoʻohana ʻana i nā kumuwaiwai e nā hawksbills i nā kaiaola kai. Me ka hoʻohana ʻana i ka nānā ʻana i ka isotope paʻa o ka ʻiʻo hawksbill scute a me nā mea pio (Porifera – sea sponges) mai kahi ʻāina ʻai i ʻike ʻia, e loiloi au i nā kumu hoʻohana waiwai o ka heluna kanaka hawksbill Long Island.

E kālailai au i nā laʻana scute i hōʻiliʻili ʻia no ka loaʻa ʻana o kahi moʻolelo isotopic piha o ka ʻiʻo keratin, no kahi ʻāpana o ka heluna kanaka o Long Island. E ʻae nā waiwai isotope paʻa ʻo Sponge stable no ka ʻimi ʻana i kahi kumu hoʻonui trophic (ka ʻokoʻa ma waena o ka waiwai isotopic o kahi mea ʻaihue a me kāna mea pio) no nā hawksbills i loiloi ʻia. E hoʻohana pū ana au i ka ʻikepili hānau keiki no ka wā lōʻihi a me ka ʻimi ʻana i ka ʻike noaging wahi. E kōkua kēia i ka ʻike ʻana i nā wahi noho hawksbill ʻoi aku ka maikaʻi a me ka nāwaliwali a kākoʻo i ka hoʻonui ʻana i nā hana palekana no kēia mau wahi kai.

Aʻo hou mai:

E ʻike hou no ka Boyd Lyon Sea Turtle Fund maanei.
