Ay, istiridyeler de dahil olmak \u00fczere bir\u00e7ok deniz canl\u0131s\u0131n\u0131n davran\u0131\u015flar\u0131 \u00fczerinde ince ama derin bir etkiye sahiptir. Biology Letters dergisinde yay\u0131nlanan yak\u0131n tarihli bir ara\u015ft\u0131rma, Pasifik istiridyelerinin (Crassostrea gigas) kabuklar\u0131n\u0131 ay d\u00f6ng\u00fcs\u00fcyle senkronize bir \u015fekilde a\u00e7\u0131p kapatt\u0131\u011f\u0131n\u0131 ortaya koyuyor.<\/p>\n\n
Ara\u015ft\u0131rmac\u0131lar, Frans\u0131z sahili boyunca 12 Pasifik istiridyesini suya b\u0131rakt\u0131lar ve \u00fc\u00e7 ay d\u00f6ng\u00fcs\u00fc boyunca kabuk hareketlerini izlediler. Elektrotlar kullanarak, istiridyelerin kabuk a\u00e7\u0131kl\u0131klar\u0131n\u0131n geni\u015fli\u011fini her 1,6 saniyede bir \u00f6l\u00e7t\u00fcler ve verileri ay d\u00f6ng\u00fcs\u00fcyle kar\u015f\u0131la\u015ft\u0131rd\u0131lar.<\/p>\n\n
Sonu\u00e7lar net bir \u00f6r\u00fcnt\u00fc g\u00f6sterdi. Ay b\u00fcy\u00fcd\u00fck\u00e7e veya dolunay haline geldik\u00e7e istiridyeler, kabuklar\u0131n\u0131 hi\u00e7bir zaman tamamen kapatmadan daraltt\u0131lar. Tersine, ay azalmaya ba\u015flad\u0131\u011f\u0131nda veya yeni ay evresine d\u00f6nd\u00fc\u011f\u00fcnde, kabuklar\u0131n\u0131 tekrar geni\u015flettiler.<\/p>\n\n
Bu, istiridyelerin ay \u0131\u015f\u0131\u011f\u0131n\u0131n yo\u011funlu\u011fu gibi do\u011frudan ipu\u00e7lar\u0131ndan ziyade i\u00e7sel bir ay saatine g\u00fcvenebilece\u011fini d\u00fc\u015f\u00fcnd\u00fcrmektedir. Do\u011frudan ay \u0131\u015f\u0131\u011f\u0131na tepki veriyor olsalard\u0131, kabuklar\u0131n\u0131 ilk d\u00f6rd\u00fcn ve son d\u00f6rd\u00fcn ayda e\u015fit \u015fekilde a\u00e7arlard\u0131 \u00e7\u00fcnk\u00fc \u0131\u015f\u0131k yo\u011funlu\u011fu benzerdir. Ancak istiridyeler bu evrelere farkl\u0131 tepki verdiler ve bu da i\u00e7sel bir takvimi i\u015faret ediyor.<\/p>\n\n
\u0130stiridyeler neden ay\u0131n evrelerini \u00f6nemsiyor? Bordeaux \u00dcniversitesi’nden \u00e7al\u0131\u015fma yazar\u0131 Laura Payton, bunun plankton hareketleriyle ilgili olabilece\u011fini \u00f6ne s\u00fcr\u00fcyor. \u0130stiridyeler, deniz suyundan plankton s\u00fcz\u00fcyor ve onu t\u00fcketiyor ve \u00f6nceki ara\u015ft\u0131rmalar, plankton hareketinin ay \u0131\u015f\u0131\u011f\u0131ndan etkilendi\u011fini g\u00f6sterdi.<\/p>\n\n
Ay d\u00f6ng\u00fcs\u00fc, istiridyeleri etkileyen tek d\u00f6ng\u00fc de\u011fildir. Ayr\u0131ca gelgit ve sirkadiyen saatleri de takip ederler. Aberystwyth \u00dcniversitesi’nden su biyolo\u011fu David Wilcockson, bu etkile\u015fimlerin karma\u015f\u0131kl\u0131\u011f\u0131n\u0131 vurguluyor: “Gelgit, ay ve sirkadiyen saatlerin ayr\u0131 mekanizmalara sahip oldu\u011funu biliyoruz, ancak bir dereceye kadar ba\u011flant\u0131l\u0131lar – ve nas\u0131l ve hangi d\u00fczeyde oldu\u011funu tam olarak bilmiyoruz.”<\/p>\n\n
\u0130stiridyeler, aya tepki veren tek deniz canl\u0131lar\u0131 de\u011fildir. D\u00fczinelerce mercan t\u00fcr\u00fc, yumurtalar\u0131n\u0131 ve spermlerini ay \u0131\u015f\u0131\u011f\u0131nda toplu halde b\u0131rak\u0131r. Baz\u0131 yenge\u00e7ler, \u00e7iftle\u015fme g\u00f6\u00e7lerinin ba\u015flang\u0131c\u0131n\u0131 i\u015faret etmek i\u00e7in ay \u0131\u015f\u0131\u011f\u0131n\u0131n yo\u011funlu\u011funu kullan\u0131r. Somon, kalamar ve plankton da ya\u015fam d\u00f6ng\u00fclerini ay ile senkronize eder.<\/p>\n\n
Ay\u0131n istiridyeler \u00fczerindeki etkisini anlamak, akuak\u00fclt\u00fcr i\u00e7in \u00f6nemlidir. \u0130stiridye \u00e7iftliklerindeki \u0131\u015f\u0131k ko\u015fullar\u0131n\u0131 manip\u00fcle ederek, istiridyelerin b\u00fcy\u00fcmesini ve \u00fcremesini optimize etmek m\u00fcmk\u00fcn olabilir. Bu olas\u0131l\u0131klar\u0131 ara\u015ft\u0131rmak i\u00e7in daha fazla ara\u015ft\u0131rmaya ihtiya\u00e7 vard\u0131r.<\/p>\n\n
