Relations between abundances of adult LDF Schindleria and the four main moon phases (the new moon “NM”, the 1st quarter “1stQ”, the full moon “FM”, and the 3rd quarter “3rdQ”) in two different datasets: one from an Indo-Pacific collection from the DANA Expedition 1928–1930 (DANA) and the other from a Red Sea collection (from the 16th Oct to the 16th Nov, 2014). Values from the DANA Expedition are always color-coded in “pink”. Panel A displays the abundances in the Red Sea color-coded per sampling site: inshore/IS reef in “yellow”, mid-shelf/MS reef in “green”, and shelf-edge/SE reef in “blue”. In Panel B and C, the Red Sea abundances are given as total values in “blue”. Panel A displays the total abundances (y-axis) for each dataset per moon phase (x-axis). The moon phases are represented by the circles on the top of the barplot and the brightest moon phase (FM) highlighted by a “light-blue” shaded box, while the darkest moon phase (NM) by a “black” shaded box. Panel B displays the coefficients of linear regression on the corrected Log₁₀ Abundances (± SE; y-axis) of each moon phase (x-axis) of the two main datasets (DANA vs. Red Sea). Panel C displays, on the left plot, the abundances of each day of sampling (as dots) within a moon phase (on the x-axis; where the moon phases are grouped by light intensity for which the 1stQ and the 3rdQ moons are grouped in the middle of the regression) and on the right plot the respective slopes of the linear regression of both datasets of which the mean does not differ significantly between the two data sets. The lowest abundances of adult LDF Schindleria were generally during the FM.
