Differential microhabitat use may be beneficial to achieving fitness in seasonally variable environmental conditions. To explore whether the microhabitat use of the nocturnal Schlegel's Japanese gecko, , varies seasonally and depends on juvenile, male, and female reproductive groups, we investigated five categorical and five quantitative measure variables of microhabitat use in a wild population both in spring and summer. Most geckos were found on white, vertical planes of concrete and plastered brick walls. None of the categorical variables (type of location, substrate, substrate color, light source, and refuge) significantly differed according to season or group, while substrate temperature and irradiance at the location where geckos were observed and the distance from the nearest potential refuge were significantly greater in summer than in spring. The quantitative measure variables did not differ among the reproductive groups. These results suggest that seasonally adjusts its microhabitat use mainly in terms of quantitative measure variables rather than categorical variables.
在季节性变化的环境条件下，不同的微生境利用方式可能有利于实现适合度。为了探究夜行性的施氏滑蜥（）的微生境利用是否随季节变化，以及是否取决于幼年、雄性和雌性繁殖群体，我们在春季和夏季对一个野生种群的微生境利用的五个分类变量和五个定量测量变量进行了调查。大多数壁虎被发现在白色的混凝土和抹灰砖墙的垂直平面上。分类变量（位置类型、基质、基质颜色、光源和避难所）在季节或群体之间均无显著差异，而在观察到壁虎的位置的基质温度和辐照度以及到最近潜在避难所的距离在夏季显著大于春季。定量测量变量在繁殖群体之间没有差异。这些结果表明，主要根据定量测量变量而非分类变量来季节性地调整其微生境利用。
