我们研究了蝾螈求偶信息素的种内和种间化学变异。通过反相高效液相色谱法分析了不同种群的约氏原齿鱼的感受性因子（PRF）和其他腺体成分的变化程度。从个人的腺体提取物显示，男性在一个人口不同的腺体成分的相对量，以及在存在和不存在的组件，包括PRF。群体之间的比较表明，每个群体都有一个独特的洗脱曲线，并在PRF和其他提取物组分的相对量显着不同。知识的自然地理变化的求偶信息素，结合行为测试的女性反应，将有助于了解信息素是如何演变的。
We examined intraand interspecific chemical variation in salamander courtship pheromones. The extent to which plethodontid receptivity factor (PRF) and other glandular components vary among populations of Plethodon jordani was analyzed by reverse-phase HPLC. Gland extracts from individuals revealed that males within a population differ in the relative amounts of the glandular components as well as in the presence and absence of components, including PRF. Comparisons between populations showed that each population had a unique elution profile and differed significantly in the relative amounts of PRF and the other extract components. Knowledge about the nature of geographic variation in the courtship pheromone, combined with behavioral tests of female response, will contribute towards understanding how the pheromone evolved.
