All authors must be listed in references. Manuscripts cannot be sent to reviewers until this requirement is met. Cite references in numerical order according to first mention in text. Ensure accuracy in spelling and details of publication. Personal communications, unpublished observations, and submitted manuscripts are not legitimate references.
Authors are responsible for the cost of printing colour illustrations.
Artwork must be prepared using professional standards and photographed as camera-ready, unmounted, glossy prints if line drawings, photomicrographs, colour, or halftones. Note that computer-generated laser prints also reproduce better if printed on glossy computer paper. Letters and locants must be uniform in size and style. Flaws will not be corrected. Photocopies of figures must be attached to each manuscript.
