  • Insect egg morphology: evolution, development, and ecology
    The exchange of gas and water across the eggshell at the proper rate is crucial for embryo development within the egg [10, 67] An eggshell’s morphology can include a complex internal structure and pores such as hydropyles and aeropyles; collectively these determine the respiratory traits of the egg [59, 67, 68]
  • Gas exchange during storage and incubation of Avian eggs . . .
    Gas exchanges are of fundamental importance for embryonic development during incubation and may affect the livability of the embryo (Tullett, 1990) The exchange of incubation gases is facilitated by the chorioallantoic membrane (CAM), which is a highly vascular structure in conjunction with the porosity of the egg shell These two structures
  • Evolution of eggshell structure during rapid range expansion . . .
    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 preventing dehydration of the embryo
  • Nesting environment may drive variation in eggshell structure . . .
    Testudines exhibit considerable variation in the degree of eggshell calcification, which affects eggshell conductance, water physiology of the embryos, and calcium metabolism of embryos However, the underlying reason for different shell types has not been explored
  • Nesting behaviour influences species-specific gas exchange . . .
    We tested the association between eggshell GH2O and putative life-history correlates of adult birds, ecological nest parameters and physical characteristics of the egg itself to investigate how variation in GH2O has evolved to maintain optimal water loss across a diverse set of nest environments
