British Poultry Science1. The cuticle acts as a barrier to prevent microbial penetration of the eggshell. The reduction in the oviposition interval with selection for egg production and the activity of clock genes in the oviduct led to testing the hypothesis that the interval between successive oviposition of eggs would be related to the deposition of the cuticle. 2.

The evolution of sensitive periods beyond early ontogeny: Bridging theory and data
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Sensitive periods, in which experiences have a large impact on phenotypic development, are most common early in ontogeny. Yet, they may also occur at later ontogenetic stages, such as adolescence.
