The Editorial Board for the Journal of Life and Earth Science invites unsolicited original papers pertaining to the fields of Life and Earth Science.

Submission of manuscript:

The submission of a manuscript will be taken to imply that the material is original and that no similar paper is being, or will be, submitted elsewhere; when accepted, the copyright of the paper becomes the property of the Faculty of Life and Earth Sciences, University of Rajshahi whose permission must be obtained to reproduce there from.

Presentation:

i) Manuscript

Manuscript must be submitted as an IBM based soft copy in MSWord/RTF format in a CD or through email as a PDF file to the editor. However, the illustrations, if required, may be submitted as hard copies. It must be written in English, in double-spaced type and preferably in A4 size with a 30mm margin all round. The papers must be consecutively numbered. Tables and captions for illustrations have to be typed separately at the end of the manuscript and their positions be indicated in the margins of the text. Following the conventional form the manuscript must include: a) Title page giving a concise specific title with the name(s) of the author(s) and institution(s) where the work was carried out. A short running title for page headings must be provided (maximum 10 words) followed by up to 5 (five) appropriate Keywords. b) Abstract will be of not more than 200 words and intelligible without reference to the main text. Next to it, a Bangla version of the Abstract is required. The manuscript will contain the headings: Title, Abstract, Keywords, Introduction, Material and Methods, Results, Discussion, Conclusion, Acknowledgements (optional) and References. Short Communications are not to follow this pattern, but must have references as usual.

ii) Style

a)Use active voice whenever feasible, and write in the first person (except in the Abstract where the third person should be used).

b)Use British conventions of spelling and grammar throughout, except in Non-British quotations and references.

c)Avoid terms that may be regarded as pejorative of contentions, eg. “man”, “Bushman”, “Game” animal.

d)Avoid footnotes except to add information below the body of a Table.

e) Do not use initial capitals for the common of plant/ animal or rock/mineral unless derived from a proper noun.

iii) Conventions

The metric system, ie. SI units must be used where necessary. Whole numbers one to nine should be spelled out (except in the Material and Methods Section) and number 10 onwards given in numerals.

iv) Tables

These must be presented to fit the page size (230 x 170 mm) without undue reduction. Tables have to be referred to as Table 1, Table 2, etc. and any sub-sections as (a), (b), etc.

v) Illustrations

There may be line drawings or photographs, which must be numbered in a single sequence and consecutively referred to in the text as Fig. 1 etc. Each figure must be on a separate page and clearly identifiable with the author’s name, short title of the manuscript and figure number. The position of each figure has to be indicated in the margin of the text. Component of figures must be labeled a, b, c etc. Caption for figures, which should be self-explanatory and must not contain details of results, have to be double-spaced typed, on a separate page. Regardless of the final size of the figure, the copies submitted must either be printed on or attached to sheets or thin cards the same size as the rest of the manuscript lest small figures can be lost and large ones damaged.

Line drawings must not be larger than twice the final size and in no circumstances should exceed 170 x 230 mm. The axes of graphs should be carefully chosen so as to occupy the space available to best advantage. When reduced, the drawing must fit into either one (83 mm) or two (172 mm) columns, preferably the former. Lines have to be bold enough to permit reduction to about 0.25-0.35 mm. Line drawings should be simple as possible. Maps, cross-sections, computer-generated figures (eg. 3-dimensional graphs), etc. with fine lines, gradations of stippling and unusual symbols, cannot be reproduced satisfactorily when reduced. Preferred symbols are open and filled circles, boxes and triangles, and these should be used consistently. Lettering should be kept to a minimum and should be self-explanatory and unambiguous and of sufficiently high quality and size to be clearly visible after reduction to final size.

Photographs should be the same size as they would appear in the journal and must be selected to fit neatly into one column (83 mm) or two columns (172 mm). Photographs have to be labeled and numbered like line drawings. For microscopic preparations, scale bars with appropriate units (eg. 50µm) must be provided; statements of magnification are not acceptable. Original illustrations should not be sent until the paper gets accepted and will only be returned on request.

vi) Referances

Accuracy of references is the responsibility of the author(s). References must be checked against the text to ensure

(a) that the spelling of authors’ names and the dates given are consistent and (b) that all authors quoted in the text (in the descending date order if more than one) are given in the reference list and vice-versa. The full title of the paper must be given together with the first and last pages Journal titles have to be abbreviated in accordance with the International Standard (ISO 4: 1984). Book titles must be followed by the publisher and the place of publication. The name of the editor(s), if different from the author cited, has to be given.

In the text, reference must be arranged chronologically with the surname(s) of the author(s) followed by the date. Use a, b, etc. after the year to distinguish papers published by the same author(s) in the same year, eg. (Pianka, 1978a; Pianka, 1978b). Reference should not be made to unpublished data. For two authors: use both the names and the year. In case of three or more authors: use first author followed by et al. and the date. In the list, references must be arranged first in ascending alphabetical order under author(s) names(s) and then in descending chronological order if several papers by same author(s) are cited. Examples of references:

Barnby M A and Klocke J A. 1990. Effects of azadirachtin on levels of ecdysteroids and prothoracicotropic hormone-like activity in Heliothis virescens (Fabr.) larvae. J Insect Physiol 36: 125–131

Tinbergen, N. 1951. The Study of instinct. Oxford Univ. Press. London. 228 pp.

vii) Proofs

Proofs along with the original manuscript will be sent as PDF files in a CD to the author. Corrections should be made on the marked proofs, which should be returned with original manuscript. Revised proofs will not normally be sent to the author.

viii) Coprright/Offprints

It is a condition of publication in the Journal that author assigns copyright to the Faculty of Life and Earth Sciences, University of Rajshahi. This would ensure efficient handling of reproduction of articles for third party requests and wide dissemination at large. However, the Journal will supply 20 complementary free offprints of each paper to the author.

ix) Printing Charge

To partly cover the printing cost, TK. 400 /- and 200/- will be charged form the author(s) for each full paper and short communication respectively. Manuscripts are to be sent to:
