Trading offspring size for number in a variable environment: Selection on reproductive investment in female Soay sheep
1. Given energetic constraints, female reproductive strategy is expected to be shaped by a trade-off between offspring size and offspring number, the optimal resolution of which may vary with environmental conditions. 2. We tested the hypothesis that selection will favour the production of larger litters, even at some expense to offspring size, under good conditions (and vice versa in harsh environments) using data from a long-term study of an unmanaged population of Soay sheep on the islands...[Show more]
