Acorn crops and rodent populations [bank vole ( Myodes glareolus ), yellow-necked mouse ( Apodemus flavicollis ), and wood mouse ( Apodemus sylvaticus )] were monitored for 11 years (2002–2012) in mature oak commercial forests in South Moravia (the Czech Republic). Large acorn crops, marking so-called seed years, were recorded in 2003, 2006, 2009, 2010, and 2011. Acorn crops were repeated with period of 3–4 years. The abundance of all three species correlated positively with size of the acorn crop in the previous year. However, significant relationship between the size of the crop and grow of the population was found only in Apodemus flavicollis . Probably because of its food specialty, this species was most affected by acorn crops. Acorn crops had an effect on the breeding season of all monitored rodent species. In autumn of the seed years, the breeding period was prolonged in both Apodemus species; on the contrary, the crop had no major impact on bank voles. The higher the crop, the earlier A. flavicollis began to reproduce in the spring and the sooner it reached its peak and end of reproduction in a given year. The beginning, peak, and end of reproduction were significantly later in bank vole than in Apodemus spp. Lower North Atlantic Oscillation index (i.e. higher temperatures in the vegetation season and lower during winter, “NAO” hereinafter) was more suitable for Apodemus flavicollis . Higher values of the wNAO (winter NAO index) had a positive impact on Apodemus spp. while bank voles were not affected by this.

我们能否检测中欧森林环境中主要啮齿动物物种对气候和橡子作物的反应差异？

橡子作物和啮齿动物种群 [bank Vole (Myodes glareolus)、黄颈鼠 (Apodemus flavicollis) 和木鼠 (Apodemus sylvaticus)] 在南摩拉维亚成熟橡木商业林中被监测了 11 年（2002-2012 年）（捷克共和国）。2003 年、2006 年、2009 年、2010 年和 2011 年记录了大橡子作物，标志着所谓的种子年。橡子作物以 3-4 年的周期重复。所有三个物种的丰度与前一年橡子作物的大小呈正相关。然而，仅在Apodemus flavicollis 中发现了作物大小与种群增长之间的显着关系。可能是因为它的食物特长，这个物种受橡子作物的影响最大。橡子作物对所有受监测啮齿动物物种的繁殖季节都有影响。在种子年的秋天，两种姬蜂的繁殖期都延长了；相反，作物对银行田鼠没有重大影响。作物产量越高，黄颈曲霉在春季开始繁殖的时间越早，并且在特定年份达到繁殖高峰和结束的时间也就越早。银行田鼠的繁殖开始、高峰和结束明显晚于 Apodemus spp。较低的北大西洋涛动指数（即植被季节温度较高，冬季温度较低，以下简称“NAO”）更适合黄颈线虫。wNAO（冬季 NAO 指数）的较高值对 Apodemus spp 有积极影响。而银行田鼠则不受此影响。黄颈在春季开始繁殖，并且在特定年份达到繁殖高峰和结束的时间越早。银行田鼠的繁殖开始、高峰和结束明显晚于 Apodemus spp。较低的北大西洋涛动指数（即植被季节温度较高，冬季温度较低，以下简称“NAO”）更适合黄颈线虫。wNAO（冬季 NAO 指数）的较高值对 Apodemus spp 有积极影响。而银行田鼠则不受此影响。黄颈在春季开始繁殖，并且在特定年份达到繁殖高峰和结束的时间越早。银行田鼠的繁殖开始、高峰和结束明显晚于 Apodemus spp。较低的北大西洋涛动指数（即植被季节温度较高，冬季较低，以下简称“NAO”）更适合黄颈线虫。wNAO（冬季 NAO 指数）的较高值对 Apodemus spp 有积极影响。而银行田鼠则不受此影响。“NAO”（以下简称“NAO”）更适合黄颈线莲。wNAO（冬季 NAO 指数）的较高值对 Apodemus spp 有积极影响。而银行田鼠则不受此影响。“NAO”（以下简称“NAO”）更适合黄颈线莲。wNAO（冬季 NAO 指数）的较高值对 Apodemus spp 有积极影响。而银行田鼠则不受此影响。
