Ke hoʻolaha nei i ka 2024 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 Jaime Restrepo ka mea lanakila o kēia makahiki.

E heluhelu i kāna hōʻuluʻulu noiʻi ma lalo nei:

Noho nā honu moana i nā kaiaola ʻokoʻa i ko lākou pōʻaiapuni ola; Noho maʻamau lākou i nā wahi ʻai i wehewehe ʻia a neʻe i kēlā me kēia hapalua makahiki i nā kahakai nesting i ka wā e lilo ai lākou i mea hana hānau (Shimada et al. 2020). ʻO ka ʻike ʻana i nā wahi noho like ʻole i hoʻohana ʻia e nā honu moana a me ka pilina ma waena o lākou ke kī nui e hoʻopaʻa mua i ka pale ʻana i nā wahi e pono ai e hoʻokō i kā lākou kuleana kaiaola (Troëng et al. 2005, Coffee et al. 2020). ʻO nā ʻano ʻano lele nui e like me nā honu kai, e hilinaʻi i nā kaiapuni nui e ulu ai. No laila, ʻoi aku ka maikaʻi o nā hoʻolālā hoʻomalu no ka pale ʻana i kēia mau ʻano i ke kūlana o ka loulou nāwaliwali loa ma ke ala neʻe. Ua hoʻomaʻamaʻa ʻo Satellite telemetry i ka hoʻomaopopo ʻana i ka ecology spatial a me ka neʻe ʻana o nā honu moana a hāʻawi i ka ʻike i ko lākou biology, ka hoʻohana ʻana i ka nohona a me ka mālama ʻana (Wallace et al. 2010). I ka wā ma mua, ua hoʻomālamalama ka hahai ʻana i nā honu nesting i nā ala hele a kōkua i ka ʻimi ʻana i nā wahi ʻai (Vander Zanden et al. 2015). ʻOiai ka waiwai nui o ka telemetry satellite e aʻo ana i ka neʻe ʻana o nā ʻano mea, hoʻokahi drawback nui ʻo ke kumukūʻai kiʻekiʻe o nā mea hoʻouna, e alakaʻi pinepine ai i ka nui o ka laʻana. No ka hoʻopau ʻana i kēia pilikia, ua lilo ka stable isotope analysis (SIA) o nā mea maʻamau i loaʻa i ke ʻano he mea pono e ʻike i nā wahi i pili i ka neʻe ʻana o nā holoholona i nā kaiapuni kai. Hiki ke nānā ʻia nā neʻe neʻe ʻana ma muli o nā gradients spatial i nā waiwai isotope o nā mea hana mua (Vander Zanden et al. 2015). Hiki ke wānana ʻia ka māhele ʻana o nā isotopes i nā mea kūlohelohe a me nā mea ʻole e wehewehe ana i nā kūlana kaiapuni ma waena o nā unahi ākea a me ke kino, e hana ana i nā ʻāina isotopic a i ʻole isoscapes. Hoʻokomo ʻia kēia mau hōʻailona biochemical e ke kaiapuni ma o ka hoʻoili ʻana o ka trophic, no laila ua hoʻopaʻa inoa ʻia nā holoholona āpau i loko o kahi kikoʻī me ka ʻole e hopu ʻia a kau ʻia (McMahon et al. 2013). ʻO kēia mau hiʻohiʻona e ʻoi aku ka maikaʻi o nā ʻenehana SIA a ʻoi aku ka maikaʻi o ke kumukūʻai, e ʻae ana i ke komo ʻana i kahi laʻana nui, a me ka hoʻonui ʻana i ka ʻelele o ka heluna kanaka i aʻo ʻia. No laila, ʻo ke alakaʻi ʻana i ka SIA ma ka hoʻāno ʻana i nā honu nesting hiki ke hāʻawi i ka manawa kūpono e loiloi i ka hoʻohana ʻana i nā kumuwaiwai ma nā wahi ʻai ma mua o ka wā hānau (Witteveen 2009). Eia kekahi, hiki ke hoʻohana ʻia ka hoʻohālikelike ʻana i nā wānana isoscape e pili ana i ka SIA mai nā laʻana i hōʻiliʻili ʻia ma ka wahi aʻo, me ka ʻike ʻike i loaʻa mai ka hoʻopaʻa hou ʻana a me nā haʻawina telemetry satellite, hiki ke hoʻohana ʻia no ka hoʻoholo ʻana i ka pilina spatial i ka biogeochemical, a me nā ʻōnaehana kaiaola. No laila, kūpono kēia ala no ke aʻo ʻana i nā ʻano i loaʻa ʻole i nā mea noiʻi no nā manawa koʻikoʻi o ko lākou ola (McMahon et al. 2013). ʻO Tortuguero National Park (TNP), ma ke kahakai ʻo Caribbean ʻo Costa Rica, ʻo ia ke kahakai nui loa no nā honu kai ʻōmaʻomaʻo ma ke Kai Caribbean (Seminoff et al. 2015; Restrepo et al. 2023). Ua ʻike ʻia ka ʻikepili hoʻihoʻi ʻana mai ka hoʻihoʻi ʻana mai ka honua i nā ʻano hoʻopuehu ma hope o kēia heluna kanaka ma Costa Rica, a me 19 mau ʻāina ʻē aʻe o ka ʻāina (Troëng et al. 2005). ʻO ka mōʻaukala, ua hoʻopaʻa ʻia nā hana noiʻi ma Tortuguero ma ka ʻākau 8 km o ke kahakai (Carr et al. 1978). Ma waena o ka makahiki 2000 a me 2002, ua hoʻokuʻu ʻia nā honu he ʻumi i hoʻopaʻa ʻia mai ke kahakai mai kēia ʻāpana kahakai i ka ʻākau a hiki i nā wahi ʻai neritic mai Nicaragua, Honduras, a me Belize (Troëng et al. 2005). ʻOiai, ua hāʻawi ʻia ka ʻike hoʻihoʻi flipper-tag i nā hōʻike maopopo o ka hoʻomaka ʻana o nā wahine i nā ala hele lōʻihi, ʻaʻole i ʻike ʻia kekahi mau ala i ka neʻe ʻana o nā honu i kau ʻia ma ka satellite (Troëng et al. 2005). ʻO ka nānā ʻana i ka ʻāina he ʻewalu kilomika o nā haʻawina mua i hoʻohālikelike ʻia i ka ʻāpana pili o nā alahele neʻe i ʻike ʻia, ʻoi aku ka nui o ke koʻikoʻi o nā ala neʻe ʻākau a me nā wahi ʻai. ʻO ka pahuhopu o kēia noiʻi ʻana, ʻo ia ka loiloi ʻana i ka pilina neʻe ʻana no ka heluna honu ʻōmaʻomaʻo o Tortuguero, ma ka helu ʻana i nā waiwai isotopic kalapona (δ 13C) a me nā waiwai isotopic naikokene (δ 15N) no nā wahi noho ʻai ʻai ma waena o ke Kai Caribbean.

Nā Hualoaʻa i Manaʻoʻia

Mahalo i kā mākou hoʻāʻo ʻana ua hōʻiliʻili mākou ma mua o 800 mau laʻana kiko mai nā honu ʻōmaʻomaʻo. No Tortuguero ka hapa nui o ia mau mea, me ka hōʻiliʻili laʻana i nā wahi ʻai e hoʻopau ʻia a puni ka makahiki. Ma muli o ka SIA mai nā laʻana i hōʻiliʻili ʻia a puni ka ʻāina, e hana mākou i kahi kumu hoʻohālike isoscape no nā honu ʻōmaʻomaʻo ma ka Caribbean, e hōʻike ana i nā wahi ʻokoʻa no nā waiwai o δ13C a me δ15N i nā wahi noho kai (McMahon et al. 2013; Vander Zanden et al. 2015) . E hoʻohana ʻia kēia kŘkohu no ka loiloi ʻana i nā wahi honu e pili ana i nā honu ʻōmaʻomaʻo e pūnana ana ma Tortuguero, e pili ana i kā lākou SIA ponoʻī.
