Interaction between juvenile snail body size (shell length in mm) and timepoint sampled (in hours) predicting individual survival probability over 24 hours of desiccation stress. Fitted lines are Bernoulli generalized linear mixed model (GLMM) predictions with 95% confidence envelopes plotted over raw data points. Only one individual snail survived at the final timepoint of 48 hours, so data from that timepoint is excluded from this figure.
