Data from: Age and quality-dependent DNA methylation correlate with melanin-based colouration in a wild bird

Secondary sexual trait expression can be influenced by fixed individual factors (such as genetic quality) but also by dynamic factors (such as age and environmentally induced gene expression) that may be associated with variation in condition or quality. In particular, melanin-based traits are known to relate to condition and there is a well-characterized genetic pathway underpinning their expression. However, the mechanisms linking variable trait expression to genetic quality remain unclear. One plausible mechanism is that...

Data from: Evolution without standing genetic variation: change in transgenerational plastic response under persistent predation pressure

Transgenerational phenotypic plasticity is a fast nongenetic response to environmental modifications that can buffer the effects of environmental stresses on populations. However, little is known about the evolution of plasticity in the absence of standing genetic variation although several nongenetic inheritance mechanisms have now been identified. Here, we monitored the pea aphid transgenerational phenotypic response to ladybird predators (production of winged offspring) during 27 generations of experimental evolution in the absence of initial genetic variation...
