Incubation in a Temperate Passerine: Do Environmental Conditions Affect Incubation Period Duration and Hatching Success?

The Incubation Effect: Hatching a Solution?

Numerous anecdotal accounts exist of an incubation period promoting creativity and problem solving. This article examines whether incubation is an empirically verifiable phenomenon and the possible role therein of nonconscious processing. An Idea Generation Test was employed to examine (a) whether an incubation effect occurred and (b) the impact of different types of break on this effect. In th...

Variation in the onset of incubation and its influence on avian hatching success and asynchrony

Incubation Conditions and Broiler Performance

However, the 21 days that the chick spends in the incubator is significant proportion of its life; for a broiler killed at 40 days, 34 % of its total life span is spent in the egg. Recent research has shown that aspects of incubation and hatchery process control can have profound effects on broiler performance all the way up to slaughter weights. Often, small changes will generate significant i...

High atmospheric temperatures and ‘ambient incubation’ drive embryonic development and lead to earlier hatching in a passerine bird

Tropical and subtropical species typically experience relatively high atmospheric temperatures during reproduction, and are subject to climate-related challenges that are largely unexplored, relative to more extensive work conducted in temperate regions. We studied the effects of high atmospheric and nest temperatures during reproduction in the zebra finch. We characterized the temperature with...

The Incubation Period of Leprosy

Vkry variable incubation periods have been given by different observers, making it most difficult to make any definite, authoritative statement on the subject. Thus Ralph Hopkins of Lousiana places it at six to eight years, Besnier says it is usually four years, Iveravel in the Caucasus found it to be three to four years in a few cases where it could be definitely fixed, while Munch of South Ru...
