Sar\u0131kuyruk kayabal\u0131\u011f\u0131 (Sebastes flavidus) Pasifik Okyanusu’nun kuzeyinde yakla\u015f\u0131k 500 metre derinde ya\u015f\u0131yor. Bal\u0131klar o b\u00f6lgede k\u0131rm\u0131z\u0131 bal\u0131k, kayabal\u0131\u011f\u0131 veya okyanus levre\u011fi diye an\u0131l\u0131yor. Bu bal\u0131klar genellikle kabuklularla ve k\u00fc\u00e7\u00fck bal\u0131klarla besleniyor. <\/p>\n
11 Kas\u0131m’da hakemli bilimsel dergi Science’ta yay\u0131mlanan ara\u015ft\u0131rmayla, bu hayvanlar\u0131n uzun ya\u015fam\u0131n\u0131n anahtar\u0131 olan genler belirlendi.<\/p>\n
Daha b\u00fcy\u00fck hayvanlar\u0131n, daha yava\u015f metabolizma ve y\u0131rt\u0131c\u0131lara kar\u015f\u0131 daha g\u00fc\u00e7l\u00fc olmas\u0131 sayesinde daha uzun ya\u015fad\u0131\u011f\u0131 biliniyor. Independent T\u00fcrk\u00e7e’de yer alan bilgiye g\u00f6re; so\u011fuk ortamlar da metabolizmay\u0131 yava\u015flatarak uzun \u00f6mre yol a\u00e7\u0131yor.<\/p>\n
Yeni ara\u015ft\u0131rmaya imza atan Kaliforniya \u00dcniversitesi Berkeley Kamp\u00fcs\u00fc’ndeki ekip, uzun ya\u015fam\u0131 sa\u011flayan fakt\u00f6rleri tespit etmek i\u00e7in kayabal\u0131klar\u0131n\u0131 incelemenin ideal oldu\u011funu s\u00f6yledi.<\/p>\n
Zira Pasifik Okyanusu’nun kuzeyinde ya\u015fayan bu bal\u0131klar b\u00fcy\u00fckl\u00fck, ya\u015fam s\u00fcresi ve \u00e7evre olarak birbirinden \u00e7ok farkl\u0131 \u015fekilde ayr\u0131l\u0131yor.<\/p>\n
Ara\u015ft\u0131rma ekibinden biyolog Peter Sudmant, 88 kayabal\u0131\u011f\u0131 t\u00fcr\u00fcn\u00fcn genomunu incelediklerini s\u00f6yledi.<\/p>\n
Kayabal\u0131klar\u0131n\u0131n hem b\u00fcy\u00fckl\u00fckleri sayesinde hem de so\u011fuk sular\u0131 kullanarak uzun ya\u015fayabildi\u011fi tespit edildi. Bulgular, 137 spesifik genin ya\u015fam s\u00fcresini art\u0131rd\u0131\u011f\u0131n\u0131 g\u00f6sterdi.<\/p>\n
Ayr\u0131ca uzun \u00f6m\u00fcrl\u00fc t\u00fcrlerin, ins\u00fclin d\u00fczenlemeyle ili\u015fkili birden fazla gene sahip oldu\u011fu g\u00f6r\u00fcld\u00fc. Bu genler, uzun \u00f6m\u00fcrl\u00fc ba\u015fka hayvanlarda da var.<\/p>\n
Sudmant, bulgular sayesinde insanlara ve geli\u015ftirilen ila\u00e7lara dair \u00e7al\u0131\u015fmalarda odaklan\u0131labilecek genlerin belirlendi\u011fini s\u00f6yledi.<\/p>\n
Ara\u015ft\u0131rmada yer almayan, bal\u0131k ekolo\u011fu Sabrina Beyer, “\u0130nsanlar uzun \u00f6m\u00fcrl\u00fc olmak isteyebilir. Ancak bu, baz\u0131 kayabal\u0131\u011f\u0131 t\u00fcrleri i\u00e7in bir gerekliliktir” dedi.<\/p>\n
\u00c7\u00fcnk\u00fc baz\u0131 t\u00fcrlerin \u00fcreyebilecek olgunlu\u011fa ula\u015fmas\u0131 i\u00e7in y\u0131llar ge\u00e7mesi gerekiyor. Ya\u015fl\u0131 kayabal\u0131klar\u0131 da gen\u00e7lere g\u00f6re daha fazla larva b\u0131rak\u0131yor.<\/p>\n
