Ukubhengeza iBoyd Lyon Scholar yowama-2022

Rhoqo ngonyaka, iBoyd Lyon Sea Turtle Fund ibamba isifundi somfundi webhayoloji yaselwandle ophando lwakhe lugxile kumafudo olwandle. Ophumeleleyo kulo nyaka nguJosefa Muñoz.

U-Sefa (uJosefa) Muñoz wazalelwa waza wakhulela eGuam kwaye wafumana i-BS kwi-Biology kwiYunivesithi yaseGuam (UOG).

Njengomfundi onesidanga sokuqala, wafumana uthando lwakhe lophando lofudo lwaselwandle kunye nolondolozo ngelixa esebenza ngokuzithandela njengeNkokeli yokuPatroli yeHaggan (ufudo ngolwimi lwesiChamoru) Inkqubo yokuJonga, egxile ekujongeni umsebenzi wokuzalela iifudo zaselwandle. Emva kokuphumelela, uSefa wasebenza njengesazi sebhayoloji yofudo lwaselwandle kwaye wayeqinisekile ukuba ufuna ukuqhubela phambili ulwazi ngofudo lwaselwandle lwase-US Pacific Island (PIR)Iichelonia mydas). NjengeSiseko seSizwe soPhando lwezeNzululwazi, uSefa ngoku ungumfundi we-PhD ye-Marine Biology ecetyiswa nguDkt Brian Bowen kwiYunivesithi yaseHawai'i eMānoa (UH Mānoa).

Iprojekthi ye-Sefa ijolise ekusebenziseni i-satellite telemetry kunye nohlalutyo lwe-isotope oluzinzile (i-SIA) ukuchonga nokubonakalisa iindawo eziphambili zokufumana ukutya kunye neendlela zokufuduka ezisetyenziswa ngamafudo aluhlaza ahlala kwi-PIR yase-US, equka i-American Sāmoa, i-Hawaiian Archipelago, kunye ne-Mariana Archipelago. Amaxabiso e-Isotopic okutya abhaliswe kwithishu yomzimba wesilwanyana njengoko izondlo ziqokelelana ukusuka ekutyeni ixesha elide kwaye ngenxa yoko amaxabiso e-isotope azinzile kwizicubu zezilwanyana abonisa ukutya kwaso kunye ne-ecosystem apho itya khona. Ke ngoko, amaxabiso e-isotope azinzileyo anokuveza indawo yesilwanyana sangaphambili njengoko sihamba kwindawo kunye ne-isotopi yokutya eyahlukeneyo.

I-SIA iye yaba yindlela echanekileyo, nengabiziyo kakhulu yokufunda ngezilwanyana ezingafumanekiyo (umz. amafudo olwandle).

Nangona i-telemetry yesathelayithi ibonelela ngokuchaneka ngakumbi ekufumaneni indawo yokuhlala yofudo emva kokuzalela, iyabiza kwaye ngokubanzi ivelisa ulwazi kwiseti encinci yabemi. Ukufikeleleka kwe-SIA kuvumela ubungakanani besampulu enkulu emele ngaphezulu kwinqanaba labemi, enokusombulula iindawo ezixhaphakileyo ngokutya ezisetyenziswa luninzi lwamafudo aluhlaza asemva kokuzalela. I-SIA edityaniswe nedatha yetelemetry iye yavela njengendlela edityanisiweyo yokumisela iindawo ezifuna ukutya kofudo lwaselwandle, kwaye le yokugqibela ingasetyenziselwa ukusombulula iindlela zokufuduka. Ngokudibeneyo, ezi zixhobo zinokunceda ekumiseleni iindawo eziphambili kwiinzame zolondolozo lwamafudo aluhlaza asemngciphekweni wokuphela.

Ngentsebenziswano ne-NOAA Fisheries 'Pacific Islands Fisheries Science Centre Marine Turtle Biology and Assessment Programme, i-Sefa isasaze iithegi ze-GPS zesathelayithi ukufukamela iifudo zaselwandle eziluhlaza eGuam kwakunye neesampuli eziqokelelweyo zezicubu zolusu eziqokelelweyo ze-SIA. Ukuchaneka kolungelelwaniso lwe-GPS olusuka kwi-telemetry yesathelayithi kuya kunceda iindlela zokufuduka kweefudo eziluhlaza kunye neendawo zokuhlala ezifuna ukutya kunye nokuqinisekisa ukuchaneka kwe-SIA, ekusafuneka yenziwe kwi-PIR yase-US. Ukongeza kule projekthi, uphando lukaSefa lugxile kwiintshukumo zokuzalela ufudo lwaselwandle olujikeleze iGuam. Kwakhona, ngokufana nezinto eziphambili kuphando lukaBoyd Lyon, uSefa ujonge ukufumana ingqiqo malunga nofudo lwaselwandle olungamadoda ngokufunda iindlela zokukhwelana kunye nokuzalana ngokwesini kofudo oluluhlaza lwaseGuam.

U-Sefa ubonise iziphumo zokuqala zolu phononongo kwiinkomfa ezintathu zenzululwazi kwaye wabonelela ngofikelelo kubafundi besikolo esiphakathi kunye nabafundi abangekabinazidanga eGuam.

Ngexesha lakhe lentsimi, uSefa wenza kwaye wakhokela i-2022 Sea Turtle Research Internship apho waqeqesha abafundi abasithoba abavela eGuam ukuba baqhube ngokuzimeleyo uphando lwaselwandle ukurekhoda umsebenzi wokuzalela kunye nokunceda kwisampulu yebhayoloji, ukuphawula ukubonwa, ukuthegiswa kwesatellite, kunye nokwembiwa kwendlwane.
