Three-dimensional maturation reaction norms for North Sea plaice
Probabilistic maturation reaction norms (PMRNs) with up to three explanatory dimensions were estimated for female North Sea plaice. The three-dimensional PMRNs reported here (1) are the first ones to be obtained for any organism, (2) reveal the differential capacity of alternative life-history state...

Probabilistic maturation reaction norms (PMRNs) with up to three explanatory dimensions were estimated for female North Sea plaice. The three-dimensional PMRNs reported here (1) are the first ones to be obtained for any organism, (2) reveal the differential capacity of alternative life-history state variables to predict the onset of reproduction, (3) document consistent temporal trends in maturation, and (4) help disentangle the contributions of genetic and plastic effects to these trends. We first show that PMRNs based on age and weight provide slightly more accurate approximations of maturation probabilities than PMRNs based on age and length. At the same time, weight-based PMRNs imply a much wider spread of maturation probabilities than length-based PMRNs. We then demonstrate that including condition as a third explanatory variable improves predictions of maturation probability. The resultant three-dimensional PMRNs for age-length-condition or age-weight-condition not only show how, at given size and age, maturation probability increases with condition, but also expose how this impact of condition decreases with age and has changed over time. Our analysis reveals several interesting temporal trends. First, it is demonstrated that, even after removing plastic effects on maturation captured by age, length, weight, and condition, residual trends towards maturation at younger ages and smaller lengths remain.
