Environmental conditions can influence life history traits such as body condition, probability of survival, and reproductive output. For instance, energetic costs resulting from variable environmental conditions such as harsh winter conditions or low habitat quality may force individuals to defer migrations or reproduction to a subsequent year and devote resources to growth instead. The expansion of road networks and the effects of these infrastructures on animal and plant populations have received attention worldwide. Several investigators report high animal mortality rates on roads, but the relationship between these

环境条件可以影响生活史特征，如身体状况、存活概率和生殖输出。例如，恶劣的冬季条件或低栖息地质量等可变环境条件造成的能源成本可能会迫使个体将迁徙或繁殖推迟到下一年，转而将资源用于生长。公路网的扩大以及这些基础设施对动植物种群的影响受到了全世界的关注。一些研究人员报告说，道路上的动物死亡率很高，但这些之间的关系
