1. Environmental factors such as temperature, humidity and partial oxygen pressure can affect avian eggshell structure because gas exchange across the shell must allow sufficient water loss while ...

Molecular analysis of the eggshell structure of large flightless birds such as ostriches and emus provides new insights into how they evolved. The study, published today in eLife, demonstrates that ...

The direct relationship between eggshell structure and eggshell formation is well established for avian eggs, but has never been studied in depth in non-avian dinosaurs. Both biological and ...

Over their short lifetimes though, bird eggshells change their strength. For example, they get thinner and weaker before hatching begins. Now, researchers investigating eggshell structure have zeroed ...
