Oxidative stress as a mediator of life history trade‐offs: mechanisms, measurements and interpretation
The concept of trade‐offs is central to our understanding of life‐history evolution. The
underlying mechanisms, however, have been little studied. Oxidative stress results from a …

What does carotenoid-dependent coloration tell? Plasma carotenoid level signals immunocompetence and oxidative stress state in birds–a meta-analysis
Mechanisms maintaining honesty of sexual signals are far from resolved, limiting our
understanding of sexual selection and potential important parts of physiology. Carotenoid …

Not just black and white: pigment pattern development and evolution in vertebrates
MG Mills, LB Patterson - Seminars in cell & developmental biology, 2009 - Elsevier
Animals display diverse colors and patterns that vary within and between species. Similar
phenotypes appear in both closely related and widely divergent taxa. Pigment patterns thus …

Parental and Mating Effort: Is There Necessarily a Trade‐Off? (Invited Review)
One of the common assumptions in the study of the evolution of parental care is that trade‐
offs exist between parental investment and other fitness‐related traits. In general, this body …

Colourful traits in female birds relate to individual condition, reproductive performance and male-mate preferences: a meta-analytic approach
A Hernández, M Martínez-Gómez… - Biology …, 2021 - royalsocietypublishing.org
Colourful traits in females are suggested to have evolved and be maintained by sexual
selection. Although several studies have evaluated this idea, support is still equivocal …
