on prenatal hormone-mediated maternal effects are inconsistent.•Hormonal effects should …

Embryonic development is one of the most sensitive and critical stages when maternal
effects may influence the offspring's phenotype. In birds and other oviparous species …

The thermal sensitivity of early life stages can play a fundamental role in constraining
species distributions. For egg‐laying ectotherms, cool temperatures often extend …

Background In egg-laying animals, mothers can influence the developmental environment
and thus the phenotype of their offspring by secreting various substances into the egg yolk …

Maternal signals shape embryonic development, and in turn post-natal phenotypes. RNA
deposition is one such method of maternal signalling and circadian rhythms are one trait …

Recent studies have shown that the egg yolk maternal components, which are a mixture of
substances that can affect the developing embryo, do not act separately but are …

Mating outside the pair‐bond occurs frequently in socially monogamous birds, but the
benefits that females gain from this behaviour remain debated. One hypothesis is that …

Several research groups around the world have studied diverse aspects of energy
metabolism in arthropod disease vectors, with the aim of discovering potential control …

Many animals make visits outside of their territory during the breeding period, but these are
typically infrequent and difficult to observe. As a consequence, comprehensive data on extra …

Most birds are socially monogamous with both parents providing offspring care, but
sometimes individuals are observed to provision at a nest that is not their own. One possible …
