Southwood, T. R. E. (1978): Ecological methods. With particular reference to the study of insect populations. Chapman and Hall, London and New York, 524 pp. or Kareiva, P. (1983): Influence of vegetation texture on herbivore populations: resource concentrations and movement. — In: Denno, R. F. & McClure, M. S. (eds): Variable plants and herbivores in natural and managed ecosystems. Academic Press, New York, pp. 259—289. In the text references should be given as Kareiva (1983) or for taxon descriptors (Marshall, 1992). When a citation includes more than two authors, e.g. Brown, Black and White, the paper should be referred to in the text as Brown et ai, provided that this is not ambiguous. If papers by the same author(s) in the same year are cited, they should be distinguished by italic letters, a, b, c, etc., e.g. Southwood (1978a, b). References to papers "in press" must mean that the article has been accepted for publication. References to "personal communications" and unpublished work are permitted in the text only: references to papers in preparation or submitted are not permissible. At the end of the paper full names and addresses of the authors should be given. All necessary illustrations should accompany the manuscript, but should not be inserted in the text. All photographs, graphs and diagramme should be numbered consecutively in Arabic numerals in the order in which they are referred to in the text. Glossy photographs or positive prints should be sent wherever possible and should be kept to a minimum. Figures should be of good quality. Explanation of lettering and symbols should be given in the figure caption and only exceptionally in the figures. Lettering and symbols to appear on the illustration should be of sufficient size to allow for considerable reduction where necessary (usually proper for a 50% reduction in size). Scales must be indicated on micrographs, not by magnifications in the legends. Figure size must not exceed 24x30 cm. On the back of each illustration should be indicated the author's name, the figure number (in Arabic numerals), and the top of the illustration, where this is not clear. Halftones should be included only when they are essential. The following symbols should be used on line drawing: • • O • A • • etc. Legends to figures should be typed on a separate sheet. They should give sufficient data to make the illustration comprehensible without reference to the text. Between the columns of tables only one tabulation should be used, please do not use spacing in it! Tables and appendices should be constructed so as to be intelligible without reference to the text, numbered in Arabic numerals and typed on separate sheets. Every table should be provided with an explanatory caption and each column should carry an appropriate heading. Units of measure should always be indicated clearly (metric units are preferred). All tables and figures must be referred to in the text. Only standard abbreviations should be used. Arbitrary abbreviations and jargon will not be accepted. The Latin names should be given for all species (in italics) used in the investigation, although taxonomic affiliation and authority need not be provided in the title. Page proofs will be sent to the author (or the first-mentioned author in a paper of multiple authorship) for checking. Corrections to the proofs must be restricted to printers' errors. Any substantial alterations other than these may be charged to the author. Authors are particularly requested to return their corrected proofs as quickly as possible in order to facilitate rapid publication. Please note that authors are urged to check their proofs carefully before return, since later corrections cannot be guaranteed for inclusion in the printed journal. Fifty reprints free of charge will be sent to the first author. In case of any questions please consult with the editors.
