在这项研究中，我们分析了果蝇中点生殖器的雄性插入器官（阳茎）对温度的反应的表型可塑性。通过单变量统计和几何形态测量来检查阳茎的大小和形状。结果如下：首先，16.5℃饲养的果蝇比20℃饲养的果蝇具有更大的腺体；其次，两组果蝇的形状也存在显着差异，主要是在顶端区域，使用薄板样条插值函数定位；第三，阳茎性状的变异系数与果蝇的其他性状以及其他生物体的生殖器性状具有可比性。这些发现是在进化背景下进行分析的。 (c) 2005 Elsevier Ltd. 保留所有权利。
In this study, we analyzed the phenotypic plasticity of the male intromittent organ (aedeagus) of Drosophila mediopunctata genitalia in response to temperature. Size and shape of the aedeagus were examined with univariate statistics and geometric morphometrics. The following results emerged: firstly, flies raised at 16.5 degrees C had bigger aedcagi than those raised at 20 degrees C secondly, significant differences in shape were also found between the two groups of flies, mainly in the apical area, located using the thin-plate spline interpolating function; thirdly, the coefficients of variation for the traits of the aedeagus were comparable to other traits in Drosophild and likewise to genital traits in other organisms. These findings were analyzed in an evolutionary context. (c) 2005 Elsevier Ltd. All rights reserved.
