Evolution of the Avian Eggshell Biomineralization Protein Toolkit – New Insights From Multi-Omics
Frontiers in Genetics, 2021 The avian eggshell is a remarkable biomineral, which is essential for avian reproduction; its properties permit embryonic development in the desiccating terrestrial environment, and moreover, are critically important to preserve unfertilized egg quality ...

Elastic Moduli of Avian Eggshell [PDF]
Biology, 2021 We analyze 700 freshly-laid eggs from 58 species (22 families and 13 orders) across three orders of magnitude in egg mass. We study the elastic moduli using three metrics: (i) effective Young’s modulus, EFEM, by a combined experimental and numerical method; (ii) elastic modulus, Enano, by nanoindentation, and (iii) theoretical Young’s modulus, Etheory.

Advances in eggshell membrane separation and solubilization technologies
Frontiers in Veterinary Science, 2023 Eggshell membranes (ESM) contain 90% protein, 3% lipids, 2% sugars, and small amounts of minerals such as calcium and magnesium. Of the 90% of proteins present, 472 proteins species have been identified.

Eggshell colour differences in a classic example of coevolved eggshell mimicry
Biology Letters, 2023 Avian brood parasitism is a model system for understanding coevolutionary arms races, and the great reed warbler ( Acrocephalus arundinaceus , hereafter ‘warbler’) and its parasite the common cuckoo ( Cuculus canorus , hereafter ‘cuckoo’) are prime examples of this coevolutionary struggle ...
