Initial submission

Manuscripts should be submitted electronically in Microsoft Word (.doc or .docx), double-spaced and with continuous line numbering. Figures may be included in the manuscript or uploaded separately and must be sufficiently clear for peer review.
Authors are encouraged to suggest suitable reviewers and may identify individuals with a potential conflict of interest.

Revision of manuscripts

Revised manuscripts should be accompanied by a point-by-point response to all comments from the reviewers and editor, including a brief explanation of any suggested changes that have not been made.

Final submission

After acceptance, the final manuscript should be supplied as an editable Microsoft Word (.doc or .docx) file. Figures should be supplied as separate files in TIFF, JPEG, PNG, PSD, PDF or EPS format, in colour or black and white. For photographs and other image files, 300 dpi at the intended publication size is sufficient; higher resolution is also accepted. For graphs and diagrams, PDF or EPS are preferred when available. Multi-panel figures should preferably be supplied as a single file. All text, symbols and scale bars must be clearly legible. Figure legends should be provided as editable text in the manuscript, not included in the figures.
