title: Data from: Sex-dependent integration of ornamentation, personality, morphology and life history

description: 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.

 life history
 [https://doi.org/10.5061/dryad.mw6m90631](https://doi.org/10.5061/dryad.mw6m90631) 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-&gt; male / 2 -&gt; female per = 2 -&gt; nest construction / 3 -&gt; 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 -&gt; 1-year-old/ 2-&gt; ≥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.
