Abstract
Kornjače spadaju u razred gmazova. Sve morske kornjače imaju muško-ženske uzorke takve da niža temperatura inkubacije proizvodi mužjake, a viša temperatura inkubacije proizvodi ženke. Srednja temperatura je konstantna temperatura inkubacije pri kojoj će omjer spolova biti 1:1. Izračunata srednja temperatura je oko 29˚C. Kod njih postoji termosenzitivni period za determinaciju spola, a smješten je u drugoj trećini ukupnog perioda trajanja inkubacije. TSD (temperaturna determinacija spola) je u morskih kornjača prvi puta zabilježena kod glavate želve, Caretta caretta. Klimatske promjene također utječu na populaciju spomenute skupine, jer se svakim povišenjem temperature daje veća prednost razvitku ženskog spola.
Abstract (english)
Turtles belong to the class of reptiles. All sea turtles have a male-female (MF) pattern in which cooler incubation temperatures produce males and warmer incubation temperatures produce females. Pivotal temperature is the constant incubation temperature that will produce a 1:1 sex ratio. Reported pivotal temperature is approximately 29˚C. There is a thermosenzitive period for sex determination during development placed around the second third of total time of incubation. In sea turtles, TSD (temperature sex determination) was first documented in the loggerhead, Caretta caretta. Climate change is also affecting the population of the aforementioned groups, because each increase of temperature gives higher priority to the development of the female.
