Figure 5 . The Julian date adult Yellowstone Cutthroat Trout were handled at an instream weir as a function of length in Burns Creek, Idaho (Top ). Fish with smaller Julian dates correspond to those that arrived earlier. Also presented is the number of offspring produced per adult as a function of total length (mm) (Bottom ). For both sets of plots, the lower and upper hinges of rectangles correspond to the first and third quartiles (the 25th and 75th percentiles) and bars represent median values. The upper and lower whisker extend from the hinge to the largest value no further than 1.5 x the interquartile range. Data beyond the end of whiskers represent outliers.
Table 1 . Outputs from generalized linear models which sought to explain the relative predictive importance of total length and arrival time at the spawning ground on relative reproductive success of Yellowstone Cutthroat Trout in Burns Creek, Idaho. Two suites of models were run, one each for male and female adults. Parameters are as follows: Length = total length (mm), Date = Julian date of arrival at an instream weir which was directly downstream from spawning habitats.K = number of model parameters, AICc = Akaike information criteria corrected for small sample size, ∆AICc = difference between each model and the best performing model, and w i= the Akaike weight.
