  abstract  = {The pace-of-life syndrome (POLS) hypothesis posits that suites of traits are correlated along a slow-fast continuum owing to life history trade-offs. Despite widespread adoption, environmental conditions driving the emergence of POLS remain unclear. A recently proposed conceptual framework of POLS suggests that a slow-fast continuum should align to fluctuations in density-dependent selection. We tested three key predictions made by this framework with an ecoevolutionary agent-based population model. Selection acted on responsiveness (behavioral trait) to interpatch resource differences and the reproductive investment threshold (life history trait). Across environments with density fluctuations of different magnitudes, we observed the emergence of a common axis of trait covariation between and within populations (i.e., the evolution of a POLS). Slow-type (fast-type) populations with high (low) responsiveness and low (high) reproductive investment threshold were selected at high (low) population densities and less (more) intense and frequent density fluctuations. In support of the predictions, fast-type populations contained a higher degree of variation in traits and were associated with higher intrinsic reproductive rate (r(0)) and higher sensitivity to intraspecific competition (gamma), pointing to a universal trade-off. While our findings support that POLS aligns with density-dependent selection, we discuss possible mechanisms that may lead to alternative evolutionary pathways.},

  abstract  = {Personal values and personality traits are related yet distinguishable constructs linked to mental health. The present study extends the current literature on personal values and personality traits by investigating the associations between the higher-order dimensions of personal values (i.e., general values factor, conservation, and self-transcendence), trait emotional intelligence (TEI), and mental health problems (i.e., depressive, anxiety, and somatoform syndromes). The study draws on a cross-sectional online sample of N = 618 young German adults. Global TEI and all four TEI factors (i.e., well-being, sociability, emotionality, and self-control) correlated positively with the g-value factor but negatively with conservation. Emotionality was also positively related to self-transcendence. Mental health problems correlated positively with conservation and negatively with the general values factor. When the effects of global TEI were accounted for, conservation but not the general values factor remained significantly related to mental health problems. Global TEI fully mediated the relationship between the g-value factor and mental health problems and partially mediated the association between conservation and mental health problems. The implications of these results are discussed.},
