In presenting data, authors should anticipate the
limitations set by the size and layout of the journal. Large and complex
tables, figures and maps should be avoided in the main paper, but can be
included in a data appendix for use by reviewers.
Figures should be saved in a neutral data format such as JPEG, TIFF or
EPS. PowerPoint and Word graphics are unsuitable for reproduction. Please
do not use any pixel-oriented programmes. Scanned figures (in JPEG and TIFF
formats) should have a resolution of 300 dpi (halftone) or 600 to 1200 dpi
(line drawings) in relation to the reproduction size.
Any tables and figures that are included in the main text of the paper
should be numbered separately, in the sequence that they are mentioned in
Each table and figure should be presented on a separate page of the manuscript,
with a brief and self-explanatory title. All text should be clearly legible,
and all graphics and legends should be easily distinguished when printed
in black and white. Tables should use horizontal lines only, with only blank
space to separate columns.
Notes under each table and figure should be used to explain and specify
the source of all data shown.
