1.在本研究中，如何季节性的翅膀颜色可塑性的七叶树蝴蝶（Junonia coenia Hubner）在不同气候区域的种群之间的差异，以及这些差异是否是由区域环境差异或反映遗传差异的可塑性。利用博物馆标本数据，它表明，七叶树翅膀颜色的变化是更大的人口从潮湿和亚热带气候的美国东部。S. A.比来自美国西部沙漠和地中海气候的种群要多。S. A.3.博物馆标本数据进一步表明，东部种群的翅膀颜色与白天长度和温度的季节变化密切相关，而西部种群的翅膀颜色与这些线索的相关性很弱。比较南加州和北卡罗来纳州种群的受控培养箱实验表明，翅膀图案变化的区域差异可归因于西部种群对环境变化的鲁棒性显著增加。总之，这些实验表明，虽然表型变异可能受到环境因素的影响，但这种变异的范围在不同地区的种群之间可能存在遗传差异。
1. In the present study, how seasonal wing colour plasticity in buckeye butterflies (Junonia coenia Hubner) differs between populations in different climatic regions, and whether these differences are explained by regional environmental differences or reflect genetic divergences in plasticity is addressed.2. Using museum specimen data, it is shown that buckeye wing colour variation is much greater in populations from the humid and subtropical climates of the eastern U. S. A. than in populations from the desert and mediterranean climates of the western U. S. A.3. Museum specimen data further show that wing colour in eastern populations is strongly correlated with seasonal variation in day length and temperature, whereas wing colour in western populations is only weakly associated with these cues.4. Controlled incubator experiments comparing Southern California and North Carolina populations suggest that regional differences in wing pattern variation are attributable to dramatically increased robustness to environmental variation in western populations.5. Together these experiments show that while phenotypic variation can be influenced by environmental cues, the range of this variation can genetically diverge between populations in different regions.
