Fig. 1: Results of Correlated Random Walk-von Mises (CRW-vm) and Correlated Random Walk resampling (CRW-r).
From: Evidence for a consistent use of external cues by marine fish larvae for orientation
CRW-vm analysis at the species level based on the diagram in Fig. 2c for the scuba-following trials (a), and for the DISC trials (b) with various number of samples-per-trial: Nobs = 21 (a), 300, 90, and 180 (b). Crosses represent means ± 95% CI of the observed (RΔθ, Rθ) pooled by species. Crosses with dashed lines in b represent species with Nobs different than 180, see Table 1 for more details. The 5th, 10th, 20th,…., 90th, and 95th quantiles of the \({R}_{{\theta }_{0}^{{vm}}}\) distribution is represented in grey contours, with thicker contours for the 5th and 95th quantiles. Thick blue line in a and b represents \({\bar{R}}_{{\theta }_{0}^{{vm}}}\). Species names are ordered top-down according to their Rθ means and correspond in color to their respective crosses in a and b. Crosses with dotted lines in a represent DISC trials, which were subsampled to Nobs = 21; for these species, colors match the names in b. The species’ full names are provided in Table 1. Chi-square goodness of fit plots comparing the \({\hat{R}}_{\theta }\) quantiles distributions (black bars) to the null quantile distributions (grey bars) for CRW-vm (c) and CRW-r (d). e A heatmap of all trial counts binned at 5% increments according to their \({\hat{R}}_{\theta }\) quantiles in the CRW-vm and CRW-r analyses.
