Over the past decade, birds have proven to be excellent models to study hormone-mediated
maternal effects in an evolutionary framework. Almost all these studies focus on the function …

Publisher Summary This chapter discusses the physiology, ecology, and behavior of
hormones in avian eggs. The main source of hormones found in avian eggs is the maturing …

Physiological Adaptations for Breeding in Birds is the most current and comprehensive
account of research on avian reproduction. It develops two unique themes: the consideration …

The science of genetics is undergoing a paradigm shift. Recent discoveries, including the
activity of retrotransposons, the extent of copy number variations, somatic and chromosomal …

Incubating new ideas about avian reproduction/SJ Reynolds & DC Deeming--The fossil
record and evolution of avian egg nesting and incubation/DC Deeming--Nest construction …

Maternal hormones in the yolk of birds' eggs have been a focus of attention in behavioral
and evolutionary ecology stimulated by the pioneering work of Hubert Schwabl. Since then …

Avian embryos are exposed not only to endogenous sex steroids, which are produced by
their gonads and have a key role in sexual differentiation, but also to maternal steroids …

Body condition is an important concept in behaviour, evolution and conservation, commonly
used as a proxy of an individual's performance, for example in the assessment of …

Haplodiploid species display extraordinary sex ratios. However, a differential investment in
male and female offspring might also be achieved by a differential provisioning of eggs, as …

The transfer of non-genetic resources from mother to the offspring often has considerable
consequences for offspring performance. In birds, maternally derived hormones are known …
