Abstract
Kornjače pripadaju u razred gmazova (Reptilia). Kod većine gmazova prisutna je determinacija spola uvjetovana temperaturom. Determinacija spola dijeli se na genotipski određenu determinaciju spola (GSD) i determinaciju spola određenu okolišnim faktorima (ESD), pod koju spada determinacija spola određena temperaturom (TSD). Unutar skupine kornjača mehanizmi determinacije spola mogu se znatno razlikovati. Kod kornjača su prisutne i TSD i GSD te njihovi različiti tipovi. Na spol kornjača s TSD utječe temperatura tijekom inkubacije te ovisno o temperaturi omjer spolova mladih može varirati. Zbog toga, globalno zatopljenje može imati negativan utjecaj na njihove populacije. Na nekim gnijezdilištima diljem svijeta već je primijećen veći udio ženki u gnijezdima u odnosu na mužjake. Moguće je da će se kornjače s vremenom prilagoditi na promjene no njihova spora evolucija ne ide u prilog toj teoriji. Kornjače su jedna od najugroženijih skupina kralježnjaka. Uzrok njihove ugroženosti je uglavnom čovjek, a globalno zatopljenje je samo jedan od načina kako čovjek negativno utječe na populacije kornjača.
Abstract (english)
Turtles belong to reptiles, phyllum Reptilia. Most reptile species exhibit temperature-dependent sex determination. Sex determination is divided into genotypic sex determination (GSD) and environmental sex determination (ESD), which includes temperature-dependent sex determination (TSD). In turtles, the mechanisms of sex determination can vary considerably. In turtles, both TSD and GSD and their different types are present. The sex of turtles with TSD is affected by the temperature during incubation, and depending on the temperature the sex ratio of the hatchlings can vary. Because of this, global warming can have a negative impact on their populations. A higher proportion of females in nests than males has already been observed in some nesting sites around the world. It is possible that the turtles will eventually adapt to the changes, but their slow evolution does not support that theory. Turtles are one of the most endangered groups of vertebrates. The cause of their endangerment are mainly humans. Global warming is only one of the ways in which humans negatively affect turtle populations.
