Extended Data Fig. 5: The effect of sex and density on pth2 expression in adult zebrafish.
From: The neuropeptide Pth2 dynamically senses others via mechanosensation
a, Male and female adult zebrafish (3 mpf) were sampled from the same tank. Box plots show pth2 levels in relation to the mean level of male gene expression. Unpaired, one-sided t-test, p(n = 4, t = 0.40) = 0.69. b, Box plots show pth2 levels in adult zebrafish that were kept at densities of 5 and 35 per 3.5 l for one week, respectively. Expression levels were normalized to the mean level at the lower density. Unpaired, one-sided t-test, p(n = 6, t = 2.44) = 3.4E-2. Box plots in a and b represent the median (black line), the lower and upper quartile (box) with the whiskers indicating at most 1.5 × the interquartile range. Significance is reported as follows: *P < 0.05.
