The avian egg: air-cell gas tension, metabolism and incubation time.
Abstract The O 2 and CO 2 tensions in the air cell of incubating eggs just pripr to the pipping stage were analyzed in nine species of birds. These appear to be very similar and average 104 and 37Expand

Water in the Avian Egg Overall Budget of Incubation
Synopsis. The loss of mass in eggs during incubation was examined and evidence is presented to show that this is essentially due to loss of water. The mean fraction of water lost by diffusionExpand

Scaling of Skeletal Mass to Body Mass in Birds and Mammals
New data on the allometric relationship of skeletal mass to body mass of birds and mammals indicate that the avian skeleton is not proportionately lighter than that of mammals. Pneumatization mayExpand

Gas exchange in gas gills of diving insects.
Abstract A gas gill is a gas volume bounded by a liquid-gas interface which mediates the exchange of O 2 and CO 2 between a submerged, air-breathing animal and water. Two basic types of gas gill areExpand

Gas Exchange of Avian Eggs with Special Reference to Turkey Eggs
Abstract Surveying the gas exchange of avian eggs shortly before hatching, one finds certain functions that are common among various precocial species and that suggest a basic strategy of developmentExpand

Calories, Water, Lipid and Yolk in Avian Eggs
-The contents of fresh eggs of altricial, semi-altricial, semi-precocial, and precocial birds were compared with values for yolk content gathered from the literature. The continuum of developmentalExpand
