Effect of local changes to shell permeability on the gas exchange of the avian embryo / by Kerstin Wagner.
The chicken embryo's ability to match the perfusion of its chorioallantoic membrane to regional differences in shell conductance was investigated.

IMPORTANCE OF SLOW EMBRYONIC DEVELOPMENT IN OFFSPRING AND ADULT IMMUNE FUNCTION
… quality. For example, in birds, slow rate of embryonic development is thought to enhance immune function; however, tests of the trade-off show mixed results for adult and nestling birds. A problematic assumption of previous tests is that the length of the embryonic period represents the …

The role of incubation temperature in determining avian phenotype: implications for avian ecology, life history evolution, and conservation
… temperatures are a defining component of the avian developmental environment. Aspects of the nest environment may be an important and overlooked maternal effect in birds as nearly all birds physically incubate their eggs, thus providing a clear link between parental behavior and the …

Spatial and temporal influence on the specification of migratory somite cells : experimental studies with avian embryos
Zellen der lateralen Dermomyotomkante der brachialen Somiten unterliegen einer Delamination und wandern danach in die Extremitätenknospe ein. Es ist bekannt, daß diese migrierenden Zellen die Extremitätenmuskulatur bilden. Darüber hinaus sind sie Vorläufer von Endothelzellen sowohl für Blut- als …
