...), incubation duration, hatchling mass and length, and sex ratio. We found that substrate moisture had a small effect across most traits but significantly affected body size (i.e., length and mass), with wetter conditions producing longer and heavier hatchlings. Temperature also moderated the effect of moisture...

.... However, exposure to elevated temperatures and prenatal corticosterone could have interactive effects on developing animals that affect physiology and life-history traits across life. We tested interactions between incubation temperature and prenatal corticosterone exposure in the delicate skink...

...Lara do Amaral-Silva; Markus Lambertz; Fernando José Zara; Wilfried Klein; Luciane Helena Gargaglioni; Kênia Cardoso Bícego ABSTRACT The embryonic development of parabronchi occurs mainly during the second half of incubation in precocious birds, which makes this phase sensitive to possible...

...Melanie D. Massey; Sarah M. Holt; Ronald J. Brooks; Njal Rollinson ABSTRACT For many oviparous animals, incubation temperature influences sex through temperature-dependent sex determination (TSD). Although climate change may skew sex ratios in species with TSD, few available methods predict sex...

...Duncan Jackson; Jamie E. Thompson; Nicola Hemmings; Timothy R. Birkhead ABSTRACT Birds are arguably the most evolutionarily successful extant vertebrate taxon, in part because of their ability to reproduce in virtually all terrestrial habitats. Common guillemots, Uria aalge , incubate their single...

... benefits to the parent. Sex ratio manipulation in birds is not widely documented, and revealing the mechanisms for altered sex ratios in vertebrates remains a compelling area of research. Incubation temperature is a key component of the developmental environment for birds, but despite its well-documented...

... as by the resulting eggs during their incubation. We found that higher night-time temperatures during the ovarian cycle increased the probability of reproductive success and decreased the duration of the reproductive cycle, but did not affect embryo stage or size at oviposition, clutch size, egg mass or relative...

...S. E. DuRant; G. R. Hepp; I. T. Moore; B. C. Hopkins; W. A. Hopkins SUMMARY Early developmental experiences, such as incubation conditions, can have important consequences for post-hatching fitness in birds. Although the effects of incubation temperature on phenotype of avian hatchlings are poorly...

... is the first involving undisturbed animals, and determines the EE/ f H relationship in naturally fasting and freely incubating or captivity-acclimatized male and female king penguins. EE determination was based on (1) the measurement of body mass loss during periods of phase II fasting, and (2) the calculation...

...Christina L. Hammond; Biggy H. Simbi; Neil C. Stickland SUMMARY The chick embryo, developing in the egg, is an ideal system in which to investigate the effects of incubation environment on the development of the embryo. We show that raising the temperature of the eggs by just one degree,from 37.5°C...

...Juli L. Black; Warren W. Burggren SUMMARY Chronic exposure to a low incubation temperature clearly slows the development of poikilothemic chicken embryos (or any other poikilotherms), but little is known about the more subtle developmental effects of temperature,especially on physiological...
