Correlations between temperature and growth rate may be used to build clusters of growth curves. (Top) Growth curves for the organism Salmonella spp. recorded at pH values of between 5 and 5.1 show a strong correlation (0.90) between their estimated growth rate and the temperature conditions in which they were grown. (Bottom) Clustering by temperature reveals clear grouping and when coloured by estimated growth rate this is well maintained. Clusters in the tree are labelled by temperature and the leaves coloured by growth rate. Colours are the same in both the top and bottom plots (high growth rate is purple, low growth rate is green). These clusters can therefore be used to give prior knowledge for improved parameter estimation
