Reproductive changes have been observed in painted turtles (Chrysemys picta) from a site
with known contamination located on Cape Cod, MA, USA. We hypothesize that these …

In the diamondback terrapin, Malaclemys terrapin, males hatch at incubation temperatures
below 28° C whereas females hatch at temperatures above 30° C. When estrogen is applied …

摘要通过组织学方法观察了泽蛙(Rana limnocharis) 原始生殖细胞(PGCs) 的迁移,
原始性腺的形成和性腺分化, 并且探讨在不同的培育温度条件下性腺分化的差异 …

The sex of Japanese flounder (Paralichthys olivaceus) is easily altered by water temperature
or sex steroid hormone treatment during the period of sex determination. We have …

In many reptile species, sexual differentiation of gonads is sensitive to temperature during a
critical period of embryonic development (thermosensitive period, TSP). Experiments carried …

In the turtle Emys orbicularis, sexual differentiation of gonads is temperature-dependent.
Oestrogens have been shown to be involved in this phenomenon and temperature has been …

Rana rugosa is unique among frog species in that it has two distinct types of sex
chromosomes in two separate forms (XX/XY and ZZ/ZW). Treatment with sex steroids can …

Steroids are known to play a crucial role in gonadal sex differentiation in many non-
mammalian vertebrates, but also in the gonadal sex change of hermaphroditic teleosts. We …

It has been shown in some species that fetal testes produce testosterone early in gestation.
This study investigated the possibility that fetal testosterone may be reflected in maternal …

Gonadal sex in the red-eared slider turtle, Trachemys scripta, is determined by incubation
temperature during embryonic development. Evidence suggests that temperature …
