The role of plasticity, trade-offs, and feedbacks in shaping behavioral correlations

چکیده
Abstract How behaviors vary among individuals and covary with other has been a major topic of interest over the last two decades, particularly in research on animal personality, behavioral syndromes, trade-offs life-history traits. Unfortunately, proposed theoretical conceptual frameworks explaining seemingly ubiquitous observation (co)variation have rarely successfully generalized. For example, “pace-of-life syndrome hypothesis” proposes that behaviors, life-history, physiological traits should be correlated predictable manner. However, these predictions are not consistently upheld. Two observations perhaps explain this failure: First, phenotypic correlations between more strongly influenced by reversible plastic changes behavior than among-individual which stem from joint effects genetics developmental plasticity. Second, while trait frequently assumed to arise via trade-offs, observed pattern is consistent simple pair-wise trade-offs. A possible resolution apparent inconsistency role for provided state-behavior feedbacks. This critical because data theory represents failure our understanding evolution. These primary emphasize importance an increased focus plasticity behavior—frequently estimated then disregarded as within-individual covariances.
