Supply tables, figures and plates on separate sheets at the end of the article, with their position within the text clearly indicated on the page where they are introduced. Provide typed captions for figures and plates (including sources and acknowledgements) on a separate sheet. Electronic versions should be saved in separate files to the main body of text.

Authors are requested to follow our instructions on how to prepare and submit their figures, for more information see Artwork Guidelines below.

Present tables with the minimum use of horizontal rules (usually three are sufficient) and avoiding vertical rules except in matrices. It is important to provide clear copies of figures (not photocopies or faxes) which can be reproduced by the printer and do not require redrawing. Photographs should be preferably black and white glossy prints with a wide tonal range.
