Female ornamentation and egg carotenoids of six sympatric gobies
Journal of Fish Biology, 2009Belly colouration, gonad carotenoid concentration and skin transparency were quantified in gravidGobiusculus flavescens, as well as in females of five sympatric gobies where belly ornamentation has not been described. AlthoughG. flavescensfemales did, indeed, have far more colourful bellies than the other species, this could only in part be explained ...

The eggs of only 13 macrourid species have been reported hitherto, eight identified from free buoyant eggs and five from ripening oocytes. Eggs of 11 species had raised, hexagonally patterned ornamentation on the envelope, while two species bore only partial ornamentation. Ripening oocytes of a further eight species showed that, overall, the eggs of 13

Close to 50 species of marine Calanoid copepods have been reported to produce diapause eggs (Engel and Hirche in J Plankton Res 26:1083–1093, 2004); eggs that are viable but require a refractory phase before they hatch, sometimes after months. Diapause eggs are often described as morphologically different with respect to egg membrane ultrastructure and

External and internal quality traits of eggs from different ornamental chicken breeds
Polish Journal of Veterinary Sciences, 2023This study analyzed the internal and external quality traits of eggs derived from hens of different breeds, including Silkie, Sultan, Cochin Bantam, Brahma and White Leghorn. The highest mean weight was noted for eggs originating from the White Leghorns breed, and the lowest was for eggs from the Cochin Bantams.

In Italy, hens for beauty contests are bred in backyard farms, characterized by the presence of few heads and self15 consumption of animal products. According to law, these small farms are not subject to animal registration on national databases and are not submitted to official inspections by official veterinarians. Fipronil belongs to the category of

Cyst ornamentation in aquatic invertebrates: a defence against egg-predation
Hydrobiologia, 2002Eggs, including encysted embryos (cysts) of aquatic invertebrates may not only be thick-walled, but also provided with various external ornamentations such as spines and honeycombings. We argue that these provide protection, additional to that of the walls themselves, against invertebrate predators, and test this idea by offering intact (honeycombed ...

The fitness‐related consequences of egg size, independent of the influences of parental quality, are poorly understood in altricial birds. Not only can egg size and parental quality influence growth and survival, but each could influence the development of condition‐dependent plumage coloration in offspring.

The patterns of exochorion ornaments on eggs of seven South American Lutzomyia sand fly species were analyzed by scanning electron microscopy (SEM): Lutzomyia (Lutzomyia) cruzi (Mangabeira 1938), Lutzomyia (Micropygomyia) evandroi (Costa Lima and Antunes 1936), L. (Nyssomyia) intermedia (Lutz and Neiva 1912), L.
