The development of behaviour in four species of Sciurid rodents, having terrestrial, arboreal and gliding way of life, is quantified and compared. The studied species are: Spermophilus columbianus, Spermophilus lateralis, Tamiasciurus hudsonicus and Glaucomys sabrinus. For each behaviour pattern the earliest and latest age of emergence is given along with a mean calculated for a series of young of each species. The development of locomotion, feeding, comfort, alertness, exploration, nest building and social behaviour and the principal events of physical development are analysed. The discussion shows that the specific differences in ontogenetic rate are controlled by a series of factors including predation pressure, hibernation and the specific complexity of locomotion.
对四种具有陆生、树栖和滑翔生活方式的松鼠科啮齿动物的行为发育进行了量化和比较。所研究的物种有：哥伦比亚地松鼠、侧纹地松鼠、北美红松鼠和北美飞鼠。对于每种行为模式，给出了最早和最晚出现的年龄，以及为每个物种的一系列幼崽计算出的平均值。分析了运动、进食、舒适、警觉、探索、筑巢和社会行为的发育以及身体发育的主要事件。讨论表明，个体发育速率的特定差异受一系列因素控制，包括捕食压力、冬眠和运动的特定复杂性。
