Na-akpọsa 2020 Boyd Lyon Ọkà mmụta

Kwa afọ, Boyd Lyon Sea Turtle Fund na-akwado agụmakwụkwọ maka nwa akwụkwọ biology nke mmiri nke nyocha ya lekwasịrị anya na nduru mmiri. Onye meriri n'afọ a bụ Alexandra Fireman. N'okpuru bụ nchịkọta ọrụ ya.

The Jumby Bay Hawksbill Project (JBHP) nọ na-enyocha nduru oke osimiri hawksbill na Long Island, Antigua kemgbe 1987.

Ọnụ ọgụgụ ndị hawksbill na Antigua gosipụtara uto ogologo oge site na 1987-2015. Ma, ọnụ ọgụgụ nesting kwa afọ agbadala nke ọma n'afọ ndị na-adịbeghị anya. N'ihi ya, ọ dị mkpa ozugbo ịchọpụta ihe kpatara ọdịda a, dị ka mmebi nke ebe obibi nri nri. Hawksbills na-eri nri na gburugburu ebe obibi coral reef, a na-ewerekwa ya dị ka ụdị isi okwu n'ihi na ọdịda ha nwere mmetụta na-emebi emebi na gburugburu ebe obibi. Ịghọta ọrụ hawksbill na gburugburu ha dị oke mkpa maka ichekwa ụdị ha. Na, nke coral reef gburugburu ebe obibi n'ozuzu ya.

Ịmụ ihe gbasara nri anụ ụlọ nke ụdị mmiri dị ogologo oge chọrọ usoro ọhụrụ.

A na-eji nyocha isotope kwụsiri ike nke anụ ahụ na-adịghị arụ ọrụ na nke na-arụ ọrụ nke ọma n'ofe taxa iji ghọta nri anụ ahụ. Ọ kachasị, δ¹³C na δ¹⁵A na-eji ụkpụrụ N eme ihe n'ọtụtụ ebe iji buru amụma ebe nri nri na ọkwa trophic nke ndị na-eri mmiri. Ọ bụ ezie na ngwa isotope nwere nduru oké osimiri amụbaala n'oge na-adịbeghị anya, ọmụmụ isotoppe nke hawksbills adịchaghị adịkarị. Na, nyocha usoro oge nke Caribbean hawksbill keratin isotope mejupụtara bụ nke na-anọghị na akwụkwọ. Ihe ndekọ nke akụkọ ihe mere eme trophic echekwara na carapace keratin nwere ike inye usoro dị ike maka ịlele akụrụngwa nke hawksbills na-eji na gburugburu ebe obibi. N'iji nyocha isotope kwụsiri ike nke anụ ahụ hawksbill scute na ihe anụ oriri (Porifera - sponge mmiri) sitere na ebe a na-eri nri a ma ama, m ga-enyocha usoro iji akụrụngwa nke ndị Long Island hawksbill.

M ga-enyocha ihe nlele scute anakọtara iji nweta ndekọ isotopic zuru oke nke anụ ahụ keratin, maka mpaghara nke ndị Long Island. Ụkpụrụ isotope kwụsiri ike nke sponge ga-enye ohere maka nyocha nke ihe na-eme ka trophic dịkwuo mma (ọdịiche dị n'etiti uru isotopic nke onye na-eri anụ na anụ anụ ya) maka ego hawks nke a na-enyocha. M ga-etinyekwa data ọmụmụ ogologo oge yana ozi mpaghara nri achọpụtara. Nke a ga-enyere aka chọpụta ebe obibi hawksbill kachasị na-arụpụta na nke na-adịghị ike ma kwado mmụba nchebe maka mpaghara mmiri ndị a.
