Sentence examples for maturation thresholds from inspiring English sources

Another possible explanation for changes in maturation thresholds is hatchery effects.

Finally, changes in maturation thresholds might be the result of phenotypic plasticity induced by environmental change.

When targeting small fish, maturation in males evolved little, but maturation thresholds in female increased at young ages (Fig. 6).

To this end, we compared the observed PMRNs to estimates of optimal maturation thresholds, with and without fishing mortality.

Under these conditions, genetic variation in maturation thresholds might be maintained, thereby allowing more rapid responses to changes in selection.
