Abstract
Although the abiotic environment plays a critical role in shaping individual fitness, the within-nest environment and interactions among family members can also generate pronounced phenotypic variation and fitness differences among closely related individuals. Here, I answer a series of questions related to the consequences of sibling rivalry within families for the development, survival, and future reproduction of offspring, and how these are affected by variation in parental investment. I hypothesize that female and male offspring are affected differently by rearing conditions and sibling rivalry, and use a variety of approaches to manipulate the sibling-competitive environment and parental care to test my predictions.
