Growth (length) was compared in A. franciscana populations from Utah, United States of America, and Yape, Chile, and A. persimilis (population from Salinas de Hidalgo, Argentina), cultured under controlled conditions (24 degrees C, seawater 35 g/l, fed with Chaetoceros calcitrans). There were significant differences among all stages of A. franciscana (Utah) and A. persimilis, whereas we found significant differences only in two stages of A. persimilis and A. franciscana (Yape); both A. franciscana had similar total lengths in all stages analyzed. Habitat adaptations could explain these results.
对来自美国犹他州和智利亚佩的褶皱臂尾轮虫种群,以及来自阿根廷伊达尔戈盐沼的嗜热四膜虫(种群)在受控条件下(24摄氏度,海水35克/升,投喂角毛藻)培养时的生长(体长)进行了比较。褶皱臂尾轮虫(犹他州)和嗜热四膜虫的所有阶段之间存在显著差异,而我们仅在嗜热四膜虫和褶皱臂尾轮虫(亚佩)的两个阶段发现了显著差异;在所分析的所有阶段,两种褶皱臂尾轮虫的总长度相似。栖息地适应性可以解释这些结果。
