类固醇在协调胚胎发育中发挥着不可或缺的作用，它们可以影响一系列表型特征，包括学习和行为。内分泌干扰化合物（EDC）可以改变胚胎发育过程中类固醇依赖性表型特征。双酚 A (BPA) 是一种会破坏雌激素作用的 EDC，最近的研究表明，BPA 会像雌激素一样影响学习和行为。我们在胚胎发育过程中将红耳龟 (Trachemys scripta) 卵暴露于双酚 A，并在两周的时间里在改良的 T 迷宫中测试了幼龟对学习和行为的影响。我们发现行为模式在一天内和整个实验过程中发生了变化，但我们发现 BPA 治疗没有效果。此外，我们发现刚孵化的海龟的行为高度一致。这些行为因人而异，表明 T 中存在离散的行为类型。脚本幼体。幼体行为的高度重复性可能解释了我们观察到的先天偏差，值得进一步研究。
Steroids play an integral role in orchestrating embryonic development, and they can affect a suite of phenotypic traits, including learning and behavior. Endocrine disrupting compounds (EDCs) can alter steroid-dependent phenotypic traits during embryonic development. Bisphenol-A (BPA) is an EDC that disrupts the action of estrogen, and recent work indicates that BPA can affect learning and behavior similarly to estrogen. We exposed red-eared slider turtle (Trachemys scripta) eggs to BPA during embryonic development and tested hatchlings for effects on learning and behavior in modified T-mazes over the course of two weeks. We found that behavioral patterns changed within a day and over the course of the experiment, but we found no effect of BPA treatment. Further, we found that hatchling turtles were highly consistent in their behaviors. These behaviors varied among individuals, suggesting that there are discrete behavioral types inT. scriptahatchlings. The highly repetitive nature of behaviors in the hatchlings might explain the innate biases that we observed and warrants further study.
