Environmental Variation At The Onset Of Independent Foraging Affects Full-grown Body Mass In The Red Fox

Fox cubs start foraging for themselves in July, but lack the skills to catch larger prey, so hunt insects and earthworms, which are only available on wet nights.


So weather conditions in July determine their rate of growth; cubs born in hot dry summers never make up this loss, and become smaller adults. This in turn means that as adults, males have smaller territories and sire fewer cubs.


This is the first study to show that weather conditions during the period when young mammals learn to forage for themselves have a significant impact on the rest of their life.
