Radiotelemetry was used to measure the range areas, activity patterns and time budgets of 21 adult male wood mice (Apodemus sylvaticus) between May 1991 and August 1992. The study investigated variation in range, total distance travelled, speed of movement and time budgets between wood mice in the nonbreeding and breeding seasons in a deciduous woodland (n = 8 and 6 respectively). We also examined habitat differences by estimating these same parameters for wood mice inhabiting maritime sand-dunes in the breeding season (n = 7). Insufficient males of an appropriate mass for radiotracking were captured to study the sand-dune mice in the nonbreeding season. Significant variation was found across both season and site. In the breeding season, in woodland, range areas were 5 times larger than during the nonbreeding season. Wood mice on the sand-dunes exploited ranges 28 times greater than their woodland counterparts. The pattern of variation in range area was parallelled by significant differences in total distances and average speeds travelled per night. Diurnal activity, c. 60 min day, was frequently recorded, at both sites, but only, in the breeding season, which was attributed to the need to forage in order to maintain energy balance. The comparatively lower availability of food on the sand-dunes was considered the main factor explaining the greater range area, total distance moved, speed travelled and level of activity of animals at this site.
1991年5月至1992年8月期间，采用无线电遥测技术测量了21只成年雄性林姬鼠（Apodemus sylvaticus）的活动范围、活动模式和时间分配。该研究调查了落叶林地中林姬鼠在非繁殖季节和繁殖季节之间活动范围、总移动距离、移动速度和时间分配的变化（非繁殖季节和繁殖季节分别为n = 8只和6只）。我们还通过估计繁殖季节栖息在滨海沙丘的林姬鼠（n = 7只）的这些相同参数，研究了栖息地差异。捕获的用于无线电追踪的雄性林姬鼠体重不足，无法在非繁殖季节对沙丘鼠进行研究。研究发现，季节和地点之间均存在显著差异。在繁殖季节的林地中，活动范围比非繁殖季节大5倍。沙丘上的林姬鼠活动范围比林地中的同类大28倍。活动范围面积的变化模式与每晚的总移动距离和平均移动速度的显著差异相似。在两个地点均经常记录到白天活动，约为每天60分钟，但仅在繁殖季节出现，这归因于为维持能量平衡而觅食的需要。沙丘上食物供应相对较少被认为是解释该地点动物活动范围更大、移动总距离、移动速度和活动水平更高的主要因素。
