2017 Boyd N. Lyon Sea Turtle Fund Recipient

Boyd N. Lyon Sea Turtle Fund yakagadzirwa mundangariro yeBoyd N. Lyon uye inopa bhezari yegore negore kune mumwe mudzidzi webhayoroji yegungwa ane tsvakiridzo yakanangana nekamba dzemugungwa. Homwe iyi yakagadzirwa nemhuri uye nevadikani vakabatana neThe Ocean Foundation kuti vape rutsigiro kune izvo zvirongwa zvinosimudzira kunzwisisa kwedu maitiro ekamba yegungwa, zvinodiwa pekugara, kuwanda, kugoverwa kwenzvimbo uye kwechinguva, kuchengetedzwa kwekutsvagisa kunyura, pakati pezvimwe. Boyd akanga achishanda padhigirii rezvidzidzo zveBiology paYunivhesiti yeCentral Florida uye achiita tsvakurudzo paUCF Marine Turtle Research Institute muMelbourne Beach paakashaya zvinosuruvarisa achiita chinhu chaainyanya kuda kuita, achiedza kubata kamba yegungwa isinganzwisisike. Vadzidzi vazhinji vanonyorera bhezari gore rega rega, asi anogamuchira anofanira kunge aine chishuwo chechokwadi chekamba dzemugungwa sezvakaita Boyd's.

Mutambi wegore rino weBoyd N. Lyon Sea Turtle Fund Scholarship ndiJuan Manuel Rodriquez-Baron. Juan parizvino ari kuita PhD yake paYunivhesiti yeNorth Carolina, Wilmington. Hurongwa hwaJuan hunosanganisira kuongororwa kweBycatch uye physiological rates yekusunungurwa mushure mekusunungurwa kweEast Pacific leatherback turtles panzvimbo dzekudya kubva kumhenderekedzo yeCentral neSouth America. Verenga hurongwa hwake huzere pazasi:

1. Mabviro emubvunzo wetsvakiridzo 
Kamba yeEast Pacific (EP) leatherback turtle (Dermochelys coriacea) inotangira kuMexico kuenda kuChile, ine mabhichi makuru ekurera matendere muMexico neCosta Rica (Santidrián Tomillo et al. 2007; Sarti Martínez et al. 2007) uye nzvimbo dzekutanga dzekutsvagira chikafu mumvura kumahombekombe kwegungwa kwe Central uye South America (Shillinger et al. 2008, 2011; Bailey et al. 2012). Iyo EP leatherback turtle yakanyorwa neIUCN seIri Mungozi Yakanyanya, uye kuderera kunoshamisa kwenhamba yevakadzi vanogarira pamahombekombe makuru ehove zvakanyorwa (http://www.iucnredlist.org/details/46967807/0) Zvinofungidzirwa kuti pari zvino kune vashoma pane 1000 vakadzi vakuru EP leatherback turtles. Kutorwa kusingatarisirwe kwehuruva dzematehwe ekare nedzadiki dzeEP nehove dzinoshanda mukati menzvimbo dzekudyira dzemhuka idzi ndiko kunonyanya kunetsa, kana tichifunga nezvesimba guru iro matanho ehupenyu aya anawo pakuchinjana kwevanhu (Alfaro-Shigueto et al. 2007, 2011; Wallace et al. al. 2008). Mhedzisiro kubva kuongororo dzakaitwa pachiteshi chemahombekombe eSouth America dzinoratidza kuti pakati pe1000 ne2000 EP leatherback turtles dzinobatwa mumatunhu madiki ehove pagore, uye ingangoita 30% - 50% yekamba dzakabatwa dzinofa (NFWF neIUCN/SSC. Marine Turtle Nyanzvi Boka). NOAA yakanyora turtle yePacific seimwe yezvisere "Speies in the Spotlight", uye yakatemerwa kuderedza kubatwa sechimwe chezvakakosha zvekuchengetedza kudzoreredza mhuka iyi. Muna Kurume 2012, Boka Rinoshanda Nemazvikokota rakaunganidzwa kuti rigadzire Chirongwa Chekuita Redunhu kumisa nekudzoreredza kuderera kweEP leatherback turtle. Chirongwa Chekuita Nenharaunda chinosimbisa kukosha kwakakosha kwekuona nzvimbo dzine njodzi huru dzekubatwa nehove, uye rinokurudzira zvakanyanya kuwedzera kweiyo port-based marine turtle bycatch assessment zvinosanganisira Panama neColombia. Zvakare, The Regional Action Plan inobvuma kuti kufa nekuda kwekubata hove nekubata hove kunopa dambudziko guru kuEP leatherback turtle kuedza kudzoreredza, uye inoti kunzwisisa kuri nani kwehuwandu hwekufa kwemashure kwekudyidzana kwakakosha pakuongorora kwakajeka kwechokwadi chekubata hove. mhando iyi.

2. Zvinangwa 
2.1. Zivisa kuti ndedzipi ngarava dziri kudyidzana nematehwe uye kuti ndedzipi mwaka nenzvimbo dzine kukosha kwakanyanya kune izvo zvekudyidzana; zvakare, kuita mawekishopu nevabati vehove kuti vagovane zvabuda pawongororo, kukurudzira nzira dzakanakisa dzekubata nekusunungura kamba dzakabatwa, uye kukurudzira hukama hwekushandira pamwe kufambisa zvidzidzo zveramangwana.

​
2.2. Natsa fungidziro dzekufa kwekamba yeganda nekuda kwekudyidzana kwehove, uye kunyora mafambisirwo ekamba yeganda muEast Pacific nzvimbo dzinotsvaga zvekudya kuti uongorore nzvimbo dzinogona kuitika dzekudyidzana kwehove.
​
2.3. Batira pamwe nezvirongwa zvedunhu rose (LaudOPO, NFWF) uye NOAA kuratidza kubata kwematehwe turtles muhove dzeCentral neSouth America uye zivisa manejimendi sarudzo maererano nezvinangwa zvekuderedza kutyisidzira.

3. Nzira
3.1. Chikamu chekutanga (chiri kuenderera mberi) Takaita ongororo dzakamisikidzwa pazviteshi zvitatu muColombia (Buenaventura, Tumaco, neBahía Solano) nezviteshi zvinomwe muPanama (Vacamonte, Pedregal, Remedios, Muelle Fiscal, Coquira, Juan Diaz neMutis). Kusarudzwa kwezviteshi zvemafambisirwo eongororo kwakavakirwa padata rehurumende maererano nengarava huru dzekuredza dzinoshanda mukati memvura yeColombian nePanama. Zvakare, ruzivo rwekuti mafambisi ezvikepe arikudyidzana neaatherbacks uye yekutanga kuunganidzwa kwekurongeka kwekudyidzana (kuburikidza neGPS zvikamu zvakagoverwa kune vabati vehove vanoda kutora chikamu). Idzi data dzichatibvumira kuongorora kuti ndeapi mafambisi ekushanda nawo kuitira kuti titore ruzivo rwakadzama nezvekudyidzana. Nekuita misangano yenyika muna Chikumi we2017, isu tinokurudzira kupa dzidziso uye maturusi ekusimudzira kubata hove izvo zvichawedzera mikana yemashure-kusunungurwa kupona kweatherback turtles dzakabatwa mumahombekombe uye pelagic fisheries munyika mbiri idzi.
3.2. Chikamu chechipiri Tichaisa satellite transmitters uye kuitisa ongororo dzehutano nematehwe akabatwa muColombian nePanamanian refu-line/gillnet hove. Tichashanda pamwe chete nemasayendisiti ehurumende kubva kuColombian nePanamaan National Fisheries Service (AUNAP neARAP) uye vabati vehove vari kushanda munzvimbo dzine njodzi huru yekubatwa nehove, sezvinoratidzwa nekuongorora kwezviteshi. Ongororo yehutano uye zvakanamirwa nevanotapurirana zvichaitwa, maererano neakadhindwa maprotocol (Harris et al. 2011; Casey et al. 2014), nematehwe turtles akabatwa panguva yekuitwa kwemaitiro ekuredza. Masampuli eropa anozoongororwa kune chaiwo akasiyana pa-bhodhi chikepe chine poindi-ye-kutarisira analyzer, uye sub-sample yeropa inozoomeswa nechando kuti iongororwe gare gare. PAT tags icharongwa kuti ibudise kubva panzvimbo yecarapacial attachment pasi pemamiriro ezvinhu anoratidza kufa (kureva kudzika> 1200m kana kudzika nguva dzose kwemaawa makumi maviri nemana) kana mushure mekutarisa kwemwedzi mitanhatu. Tichashandisa nzira yekuenzanisira yakakodzera data rakaunganidzwa kuenzanisa hunhu hwehupenyu hwevapukunyuki, vanofa, uye huturu dzine hutano dzakabatwa mugungwa kutsvagiro yesainzi. Mafambiro epashure-kuburitswa achatariswa uye mafambiro enzvimbo neenguva mukushandiswa kwenzvimbo inozoongororwa. 24. Mibairo inotarisirwa, mafambisirwo achaitwa mhedzisiro Tichashandisa data reongororo nenhamba dzehurumende pamusoro pehukuru uye kushanda nesimba kwezvikepe zvekuredza kuti tifungidzire kuwanda kwekudyidzana kwekamba yeganda kunoitika gore negore muhove diki nedzemaindasitiri. Kufananidza kubatwa kwekamba yedehwe pakati penzvimbo dzinoredza kuchatibvumira kuziva njodzi huru nemikana yekuderedza kubata hove munzvimbo ino. Kubatanidzwa kwedata refiziology nedata rekuburitswa kwemaitiro kuchawedzera kugona kwedu kuongorora kufa nekuda kwekudyidzana kwehove. Kutevedzwa kwesatellite kwekamba dzematehwe dzakaburitswa kuchabatsirawo kuRegional Action Plan chinangwa chekuziva mapatani ekushandiswa kwepekugara uye mukana wekupindirana kwenzvimbo uye kwechinguvana kwekamba dzematehwe uye kubata hove muEast Pacific.
