Hatching Response of Aedes aegypti (Diptera: Culicidae) Eggs at Low Temperatures: Effects of Hatching Media and Storage Conditions
(Entomological Society of America, 2014-12)
In temperate regions, Aedes aegypti (L.) (Diptera: Culicidae) populations remain in the egg stage during the cold season. To ensure the start of a new breeding season, eggs should hatch at the beginning of a favorable ...
Fuzzy modeling to predict chicken egg hatchability in commercial hatchery
(Poultry Science Assoc Inc, 2012-10-01)
Experimental studies have shown that hatching rate depends, among other factors, on the main physical characteristics of the eggs. The physical parameters used in our work were egg weight, eggshell thickness, egg sphericity, ...
Activity and reproduction inMegalobulimus paranaguensis(Gastropoda, Eupulmonata): implications for conservation in captivity for a South American land snail
(Taylor & Francis Ltd, 2020-02-16)
In South America,Megalobulimusincludes a number of threatened species, as well the largest land snails on the continent. The activity patterns and reproductive aspects of this group have not been documented. This work ...
Energetic effects of pre-hatch albumen removal on embryonic development and early ontogeny in Gallus gallus
(Frontiers Media S.A., 2017)
© 2017 Peña-Villalobos, Piriz, Palma and Sabat. Studies on the yolk and albumen content in bird eggs, and the effects of variations in their relative loads in the phenotype of the birds, have revealed multiple consequences ...
Invariance of demographic parameters using total or viable eggs
(Wiley, 2015-03)
Recently Mou et al. (J. Appl. Entomol., 139, 2015 and 00) recommended that in population studies in which hatch rates vary with maternal age, demographic parameters should be calculated excluding unhatched eggs. A mathematical ...
Response to Chi, Mou, Lee and Smith
(Wiley Blackwell Publishing, Inc, 2015-04)
In our article, "Invariance of demographic parameters using total or viable eggs" by C. Hernandez-Suarez, P. Medone and J. E. Rabinovich (this issue), we provide three different mathematical proofs that the net reproductive ...
Effect of temperature on incubation period, embryonic mortality, hatch rate, egg water loss and partridge chick weight (Rhynchotus rufescens)
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2003-05-01)
The aim of this study was to determine the effects of incubation temperature (34.5; 35.5; 36.5; 37.5 and 38.5ºC), on incubation period, embryonic mortality, hatching rate, water loss and chick weight at hatch, using daily ...
Implantation failures: Success of assisted hatching with quarter-laser zona thinning
(2005-02-01)
Implantation failure after IVF is one of the factors associated with a reduced chance of pregnancy for some patients. Assisted hatching methodologies are designed to facilitate the embryo's escape from the zona pellucida, ...
Relevância do assited hatching com laser em um programa de ovo-doação utilizando banco de óvulos criopreservados: Um estudo prospectivo randomizado
(2011-05-01)
Objective: This prospective randomized trial evaluated if there is an improvement in clinical outcomes when assisted hatching is performed in embryos derived from vitrified oocytes in an ovum donation program. Methods: ...
Early life history timings in marbled rockcod (Notothenia rossii) fingerlings from the South Shetland Islands as revealed by otolith microincrement
(Springer, 2014-04)
Although it has been reported that Notothenia rossii elsewhere hatches in spring, our daily increment back-counting from the capture date in otoliths of fingerlings caught in Potter Cove, South Shetland Islands, in the ...
