Figure 2From: Maternal effects mediated by egg quality in the Yellow-legged Gull Larus michahellis in relation to laying order and embryo sexRelationships between gradient of vitamin E or total carotenoid concentrations and gradient in corticosterone concentration. Gradients along the laying sequence are expressed as (a- minus c-eggs); gradient in corticosterone concentrations was calculated based on log10-transformed values (see Methods).Back to article page
