Seasonal and sexual differences exist in growth, with all cotton rats showing higher growth rates in summer than in winter. In fall and winter the heavier animals tended to lose mass whereas lighter cotton rats gained, reducing the variability within the population. This phenomenon might account for seasonal differences in mass distributions within rodent populations. Seasonal variation in growth is related to cotton rat environment and energetics. -from Authors
