Abstract
Phenotypic integration can be defined as the patterns and strength of the covariance between traits in an organism. The pace of life syndrome (POLS) hypothesis provides a testable case of phenotypic integration as it predicts that traits that mediate the trade-off between current and future reproduction, should have coevolved with the slow-fast life-history continuum, and may thus covary across individuals of a population. Although the POLS hypothesis has received increasing attention over the last decade, there is still a need for investigating whether POLS are sex-specific or if ornamental traits can be included within the POLS framework. We used nine years of data to describe the integration patterns of ornamental coloration, personality, morphology and life history in blue tits (Cyanistes caeruleus) and whether they differed between males and females. With that aim, we fitted multivariate mixed models separating the among- from the within-individual covariances. We found that the overall integration between the studied traits was weak, but our results suggested some sex-specific covariances at the among- and within-individual levels. Besides, we found several covariances between the ornamental colors and personality in males but not in females. Finally, using structural equation models, we tested for the presence of trait modules (i.e. covariances between traits involved in the same biological function). Our results support the presence of a morphological module, not of ornamental or behavioral modules in males or females. Also, our results do not align with the POLS hypothesis, however they highlight the importance of considering sex when studying phenotypic integration.

Give a brief summary of dataset contents, contextualized in experimental procedures and results.
Description of the data and file structure
In this dataset you can find the data required to replicate the analyses in the manuscript Sex-dependent integration of ornamentation, personality, morphology, and life history.
The dataset contains information about morphology, behaviour, coloration and life-history of Corsican blue tits collected in a 9-year period. The dataset contains the following variables:
yr = year
id = individual identity of the sampled bird
pop = population where that bird was sampled
sex = 1-> male / 2 -> female
per = 2 -> nest construction / 3 -> breeding
bb = crown blue brightness
buvc =crown blue UV chroma
yb = breast yellow brightness
yc = breast yellow chroma
wing = wing length (mm)
tarsus2 = tarsus length (mm). Corresponds to the average of the tarsus measured in an individual (see methods for further details)
mass = body mass (grams)
agresivite = handling aggression
obsagr = researcher that measured handling aggression
agecod = age coded in 1 -> 1-year-old/ 2-> ≥2-year-old
cs = clutch size
nf = number of fledglings
vitesse = exploration (average speed of an individual (cm/s) during each exploratory behaviour trial).
NAs: throughout the dataset missing values for each measured variable are represented by "NA". Most NA occur in cs and nf, which are only measured in per 3, and vitesse that is only measured in per 2.
