Geographical variation in egg size dimorphism in rockhopper penguins
(Springer, 2010-04)
All crested penguins present a unique reversed hatching asynchrony: the larger second-laid egg (B-egg) hatches before the smaller first-laid egg (A-egg). Although both eggs often hatch, the A-chick generally dies of ...
Susceptibility of Nezara Viridula (L.) (Hemiptera: Pentatomidae) egg masses of different sizes to parasitism by Trissolcus Basalis (Woll.) (Hymenoptera: Platygastridae) in the field
(Sociedade Entomológica Do Brasil, 2013-11)
Egg masses of Nezara viridula (L.) are commonly parasitized by Trissolcus basalis (Woll.), and we investigated the role of size of egg masses on parasitization by T. basalis. Sentinel egg masses were exposed to parasitism ...
How Does Oocyte Uptake Occur? A Macroscopic Study of the Ovarian and Oviductal Modifications for Egg Capture in the Coral-Snake Micrurus corallinus
(2018-11-01)
The processes of follicular development, ovulation, egg capture, and egg transport vary among vertebrates. Therefore, analysis of the reproductive tract of several lineages is needed for understanding the evolutionary ...
Effects of amylin on egg quality traits of hens during the early laying period
(Brazilian Journal of Animal Science, 2023)
Effect of dietary organic selenium and zinc on the internal egg quality of quail eggs for different periods and under different temperatures
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2011-03-01)
The objective of this study was to evaluate the internal quality of eggs of Japanese quails fed diets supplemented with chelated selenium and zinc. The experiment was carried out for 120 days, and 144 birds were divided ...

Molecular Detection of Taeniid Eggs in Beetles Collected in an Area Endemic for Taenia solium
(American Society of Tropical Medicine and Hygiene, 2018)
The aim of this study was to demonstrate the presence of Taenia solium eggs in beetles collected from sources within the natural environment through molecular techniques. Fifty-four pools of beetles were collected in three ...
Irregularly calcified eggs and eggshells of Caiman latirostris (Alligatoridae: Crocodylia)
(Springer, 2013-05)
We describe irregularly calcified egg and eggshell morphologies for the first time in nests of the broad-snouted caiman, Caiman latirostris. Research is based on detailed descriptions of 270 eggs from a total sample of ...
Physical and chemical characteristics of fertile and infertile eggs of wild Caiman latirostris
(Elsevier Science, 2018-12-01)
In oviparous species, physico-chemical characteristics of eggs are an indicator of maternal physiological traits and environmental conditions of the site where the females develop. In this study, we aim to (a) determine ...
Effect of the Inclusion of Organic Copper, Manganese, And Zinc in The Diet of Layers on Mineral Excretion, Egg Production, and Eggshell Quality
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2015-10-01)
This study aimed at evaluating the replacement of inorganic copper, manganese, and zinc sources by organic sources in the diet of laying hens during the second laying cycle in trace mineral excretion, egg production, and ...
