Genetic, environmental and maternal effects on magpie nestling-fitness traits under different nutritional conditions: a new experimental approach

Rearing full siblings under different environmental conditions allows partitioning of the totalphenotypic variance of a trait into its genetic and environmental components. This, in naturalbird populations, is usually achieved by cross-fostering experimental designs. We estimatedgenetic and environmental components
