WebAug 22, 2024 · As the phenotypic optima are expected to be similar for individuals of the same species that inhabit similar environments, we frequently observe population-level responses to environmental variation, and therefore it is not unusual for patterns of phenotypic divergence to correlate to environmental differences across populations [5, 12].
WebJan 27, 2024 · Although phenotypic plasticity provides an effective way to deal with unpredictably changing circumstances, canalization of trait expression (loss of plasticity) may confer advantages in more stable circumstances by allowing optimization of traits and functions, and buffering deleterious developmental deviations [ 16, 17 ]. the shack filmwebWebAug 19, 2024 · Our results are consistent with hypotheses that diversity gradients reflect shifts in phenotypic optima signifying local temperature adaptation mediated by soil nutrient availability and metabolism. my rewards demantWebSep 10, 2024 · Abstract.
