Monitoring climate changes and habitat degradation in threatened species without negative impact to the populations can pose a considerable challenge. A rare chance to test the morphological response of wing shape and size to environmental factors on the mountain Apollo (Parnassius apollo) collected from 1938 to 1968 at a single location – Strečno mountain pass, N Slovakia presented itself in a historical collection. The canonical variate analysis showed a significant shift from a narrower to broader forewing, with more extremes in either extra broad or narrow forewings in the post- 1960 population. Analysis of existing data was conducted to determine the possible factors affecting this change. Generally, the comparative statistics of temperature and precipitation to morphology of individuals and their fluctuating asymmetry showed no, or weak, correlations. Two extreme weather events (ECEs), identified using the historical weather data, show no correlation of wing morphology to these events. Although no strong correlations can be drawn in case of the available weather data and morphology, the results of this study can be connected to strong anthropogenic effects of a large-scale road development project taking place in the vicinity of the collection site starting in November 1959 causing changes in the available habitat and therefore a shift in the wing morphology.

在历史收藏中，通过机翼几何形态学反映了帕尔马修斯阿波罗的环境压力，这可能与栖息地退化有关

监测受威胁物种的气候变化和栖息地退化而又不给种群带来负面影响，这可能是一个巨大的挑战。在1938年至1968年收集的阿波罗山（Parnassius apollo）上，一次难得的机会来测试机翼形状和大小对环境因素的形态反应，这是在斯洛伐克北部的Strečno山口上进行的。典范变量分析显示，从较窄的前兆到较宽的前兆有很大的转变，1960年后人口中超宽或窄前兆的极端情况更多。对现有数据进行分析，以确定影响这一变化的可能因素。通常，温度和降水对个体形态及其波动性不对称性的比较统计表明，无或弱。相关性。使用历史天气数据确定的两个极端天气事件（ECE）表明机翼形态与这些事件没有相关性。尽管没有可用天气数据和形态的强相关性，但这项研究的结果可以与从1959年11月开始在采集地点附近进行的大规模道路开发项目的强烈人为影响联系在一起。导致可用栖息地发生变化，从而导致机翼形态发生变化。
