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 ...

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, ...

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 ...

© 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 ...

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 ...

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 ...
