TL;DR: Of special interest are the constraints that a shared gene pool imposes on sex-specific modifications of growth and the ways that males and females overcome these constraints in response to divergent selection pressures.

TL;DR: Changes in aggression on a large temporal and spatial scale across populations of two sister taxa of bluebirds (Sialia) are studied to show that coupling of aggression and dispersal strongly facilitated the range expansion of western bluebirds across the northwestern United States over the last 30 years.

TL;DR: Accumulation of phenotypically neutral genetic variance by developmental systems and phenotypic accommodation of stress-induced effects, together with the inheritance of stress—induced modifications, ensure the evolutionary persistence of stress–response strategies and provide a link between individual adaptability and evolutionary adaptation.

TL;DR: It is suggested that by emphasizing the complexity of causes and influences in developmental systems and by making explicit the links between development, natural selection and inheritance, the study of parental effects enables deeper understanding of developmental dynamics of life cycles and provides a unique opportunity to explicitly integrate development and evolution.

TL;DR: The results supported the hypothesis that melanin-based and carotenoid-based coloration have fundamentally different signal content and suggest that combining melanin -based andCarotenoids- based coloration in comparative analyses is not appropriate.
