Reproductive senescence: new perspectives in the wild

JF Lemaître, JM Gaillard - Biological Reviews, 2017 - Wiley Online Library
According to recent empirical studies, reproductive senescence, the decline in reproductive
success with increasing age, seems to be nearly ubiquitous in the wild. However, a clear …
