Long-term decrease in coloration: a consequence of climate change?
D López-Idiáquez, C Teplitsky… - The American …, 2022 - journals.uchicago.edu
Climate change has been shown to affect fitness-related traits in a wide range of taxa; for

The condition dependence of a secondary sexual trait is stronger under high parasite infection level
Indicator models of sexual selection predict that the expression of sexual ornaments should
be condition dependent. This is only partly supported by data, as many studies do not find …

[HTML][HTML] Intra-sexual competition alters the relationship between testosterone and ornament expression in a wild territorial bird
In a reliable signalling system, individual quality is expected to mediate the costs associated
with ornamental displays, with relatively lower costs being paid by individuals of higher …

Carotenoid-based coloration predicts both longevity and lifetime fecundity in male birds, but testosterone disrupts signal reliability
Sexual selection promotes the evolution of conspicuous animal ornaments. To evolve as
signals, these traits must reliably express the “quality” of the bearer, an indicator of individual …

Condition-dependent trade-offs between sexual traits, body condition and immunity: the effect of novel habitats
Background The optimal allocation of resources to sexual signals and other life history traits
is usually dependent on an individual's condition, while variation in the expression of sexual …

Social and abiotic factors differentially affect plumage ornamentation of young and old males in an Australian songbird
Both abiotic environmental conditions and variation in social environment are known to
impact the acquisition of sexual signals. However, the influences of abiotic environmental …

Early-life silver spoon improves survival and breeding performance of adult zebra finches
KM Wilson, NT Burley - The American Naturalist, 2024 - journals.uchicago.edu
Developmental plasticity allows organisms to increase the fit between their phenotype and
their early-life environment. The extent to which such plasticity also enhances adult fitness is …
