Egg Size, Eggshell Porosity, and Incubation Period in the Marine Bird Family Alcidae
A .—Although the ultimate factors that infl uence the duration of avian incubation periods are well known, we know much less about the proximate mechanisms by which birds adjust incubation period in response to selection. We tested the hypothesis that an adjustment in eggshell porosity is one such proximate mechanism (i.e., that avian species with higher ratios of incubation period to egg size ...
متن کاملAnalysis of the Changes in Elemental Composition of the Chicken Eggshell during the Incubation Period
The egg can be considered as a primary “capsule of life”, in which all ingredients are included in precise amounts necessary to sustain the development of an embryo and give rise to birth of a healthy chick. Thus, the chicken eggshell (CE) contains ions and compounds that are necessary to generate new life, serving as a building material of the new organism. Therefore, it is not surprising that...
متن کاملLimited male incubation ability and the evolution of egg size in shorebirds.
In bird species where males incubate but are smaller than females, egg size may be constrained by male body size, and hence ability to incubate the eggs. Using data from 71 such shorebird species, we show that egg size decreases as the degree of female-biased sexual size dimorphism increases, after controlling for female body mass. Relative egg size was not related to mean clutch size. However,...
متن کاملEgg-laying sequence influences egg mercury concentrations and egg size in three bird species: Implications for contaminant monitoring programs.
Bird eggs are commonly used in contaminant monitoring programs and toxicological risk assessments, but intraclutch variation and sampling methodology could influence interpretability. The authors examined the influence of egg-laying sequence on egg mercury concentrations and burdens in American avocets, black-necked stilts, and Forster's terns. The average decline in mercury concentrations betw...
متن کاملEffects of Egg Size and Eggshell Conductance on Hatchability Traits of Meat and Layer Breeder Flocks
Eggs obtained from 46 and 42 weeks old meat (Hybro) and layer (Leghorn) breeders flocks, respectively were used to examine the effects of genetic type of birds and egg size (small, medium and large) on variables of eggshell characteristics and hatchability traits. The variables measured were egg weight (EW), egg surface area (ESA) and eggshell characteristics (shell conductance (EC), per cent s...
