Body condition of non-pregnant females (F) and males (M). Box and whisker plots of body condition of males and non-pregnant females in five sites (AM, CE, CU, DY, and NG) from autumn 2014 to spring 2018. Body condition was estimated as the residuals of weight (in grams) regressed onto length from nose to anus squared. Letters indicate groups of populations that do not differ significantly, as determined by comparisons of confidence intervals of estimated marginal means following linear modeling. Location was not a significant predictor of body condition in males, therefore males collected in the same period but different locations were pooled together. Location and a date-___location interaction term were significant when modeling females, therefore comparisons are restricted to sampling periods within locations. Figure prepared in R (version 3.5.2, R Core Team55), using ggplot2101.
