Effects of age- and state-dependent allocation on offspring size and number

Abstract:

Background: Empirical evidence from a range of taxa suggest age and condition can affect offspring size and number, but supporting theory is limited. Question: How do age and condition influence offspring size and number? Method: Dynamic state-dependent optimization. Key assumptions: We model a capital-breeding life history where an individual matures with all reserves available for reproduction. Results: We find that mortality risk and density-dependent offspring survival favour variation in...
