  • References in tables, figures, and panels should be in numerical order according to their place in the text.

The reference list

Figures and tables

When presenting exact data use a table, whereas a graph is more adequate when the aim is to illustrate a tendency. Avoid three-dimensional presentations.
Do not present your data twice (e.g. in text and table or figure). Illustrations should be submitted in .png, .jpg, .tiff or .gif format. Alternatively they can be submitted as e.g. PowerPoint or Excel files.
All illustrations should be submitted as separate files. If an illustration has been published before, we need a written permission from the copyright holder if the illustration is going to be reproduced in your article. We strongly encourage the submission of illustrations including photographs.

  • Figures should be attached in additional files preferably in .png, .jpg, .tiff or .gif format and in high resolution; 300 dpi or higher. Alternatively, they can be submitted in .pdf format.
  • Descriptive text allows up to 30 words per figure or table.
  • We urge all authors to consider the use of tables. If possible all tables should be attached in .doc format. If that is not possible tables can alternatively be submitted in .pgn or .jpg in high resolution; 300 dpi or higher.
