A list of figures with legends should be added at the end of the main text file.

The Figure files of the manuscript
The figure and its legend must be understandable without reference to the text. Levels of statistical significance and measures of effect size need to be included. Define any symbols used and define/explain all abbreviations and units mentioned. Figures submitted in color may be reproduced in color online free of charge. Please note, however, that graphs (numerical representation of data) should be black and white so that they can be printed legibly by a reader with a black and white printer.

Graphs should preferrably be uploaded as a separate pdf file. All other Figures are accepted as separate svg, jpg, eps, and png files.

Figures should have at least 800 dpi when producing line drawings, photographs a minimum of 300 dpi. All other graphics should have a resolution of at least 500 dpi. Please embed the fonts in all eps-files.
