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.
