Marker‐assisted determination of the relationship between body size and reproductive success and consequences for evaluation of adaptive life histories
Abstract We tested for differences in the predicted optimal ages at first maturity in brook charr ( Salvelinus fontinalis ) in Freshwater River, Newfoundland, when life‐history data were collated based on the marker‐assisted estimation of the relationship between body size and reproductive success r...
