Three different egg hatching mechanisms were observed under laboratory conditions in Euphausia pacifica Hansen, Thysanoessa spinifera Holmes and Thysanoessa inspinata Nemoto: backward, forward and flipping. Like all broadcast ...

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 ...

In animals, hatching represents the transition point from a developing embryo to a free-living individual, the larva. This process is finely regulated by many endogenous and environmental factors and has been shown to be ...

We assessed whether earlier hatching time in female compared to male broilers is related to differences in the duration of the actual embryonic development and/or hatching period, hematological parameters and hatchling ...

In birds, the adaptive significance of hatching asynchrony has been under debate for many years and the parental effects on hatching asynchrony have been largely assumed but not often tested. Some authors suggest that ...
