Ontogenetic changes in genetic variances of age-dependent plasticity along a latitudinal gradient.

abstract：:Reaction norms or tolerance curves have often been used to predict how organisms deal with fluctuating environments. A potential drawback is that reaction norms measured in different constant environments may not capture all aspects of organismal responses to fluctuating environments. We examined growth of the filamen...
