Welcome to the homepage for the journal, Megadrilogica.

The journal Megadrilogica publishes papers on the ecology, physiology, taxonomy, and systematics of terrestrial Oligochaeta (Annelida) - commonly referred to as megadrile oligochaetes, or simply 'megadriles'. The journal will also consider publication of papers focusing on other groups of terrestrial, freshwater, estuarine, and marine oligochaetes. Megadrilogica first began publication in September 1968. Each volume comprises 12 issues, with one to four papers per issue.

This website provides the visitor with contact information for Dr. John W. Reynolds, Editor-in-Chief of Megadrilogica, instructions to assist authors in the preparation and submission of manuscripts to be considered for publication in this journal, the cost for a current subscription to this journal, and information for the purchase of past volumes / issues.

A hyperlink to a cumulative index for all volumes and issues of Megadrilogica published to date is provided HERE.

Soon, we will compile and present an annotated guide to pertinent literature to assist biologists in their study of megadrile oligochaete worms.

Publication Schedule, Annual Subscription Information, Cost of Individual Issues: Megadrilogica is an irregular publication -- a given volume (12 issues) may be published over a period of time that is less than, or greater than, a calendar year; this is dependent upon submission, review, and acceptance of manuscripts. The current volume (No. 15) is now being finalized. Beginning with Volume 16 (mid-2013), the subscription rate will be USD $70.00 per volume; most single issues are available for USD $10.00. Postage for volume and single issue purchases is included for Canada and U.S. postal addresses; postage for mailing volume and single issue purchases to foreign addresses will be higher. Note that subscription rates (and cost for an individual issue) may be higher if one or more lengthy papers comprise the issue. Please contact Editor Reynolds prior to sending funds.

Abstracting and Indexing: Megadrilogica is currently abstracted by and deposits all published issues with Thompson Reuters and EBSCO Information Services.  For those authors who use ResearchGate®, their abstracts and papers are available there. 

Instructions for Authors: Authors considering Megadrilogica for review and publication of their manuscripts in Megadrilogica are required to:

1) follow the format of recent issues of the journal when preparing their manuscript,  and  2) secure two or more independent reviews of their manuscript prior to its submission to Editor Reynolds for consideration. 

Authors who do not have English as their 'native' language must secure a review and assistance from one or more colleagues who do speak and write fluently in English prior to submission of the manuscript to Editor Reynolds for consideration.

Most papers published in Megadrilogica are in English; papers in French and Spanish are also welcome, as long as an English abstract, and resumé in French or resumen in Spanish (as applicable) are included. Abstracts in other languages are also encouraged, particularly when pertinent to the region of focus by the manuscript (e.g., abstract in Greek for lumbricids of Greece; abstracts in Tamil, Hindi, and Kannada for earthworms from several regions in India; abstract in Mayan for earthworm records from Beliz, C.A.; abstract in Ojibway [Latin and pictograms] for earthworm records from the Rainy River District in north western Ontario, and yet other papers with pertinent abstracts in Bangla, Bulgarian, Burmese, Catalan, Chinese, Dutch, Esperanto, Estonian, Finnish, Gaelic, Hindi, Hungarian, Indonesian, Japanese, Lao, Latvian, Lithuanian, Macedonian, Malayalam, Navajo, Norwegian, Portuguese, Romanian, Serbian, Slovakian, Slovenian, Swedish, Tagalog, Thai, Turkish, Ukrainian, and / or Welsh).

The inclusion of six to eight key words is required; additional keywords will also be considered.

By following the manuscript requirements, above, authors will be assured a more timely review process by the journal's editorial board prior to acceptance for publication. The Editor-in-Chief, after consultation with the journal's editorial board and outside referees, will make the final decision regarding the suitability, scientific worthiness, and acceptance of manuscripts submitted for publication.

Page Charges: Page charges (text) will be USD $40.00 per printed page; a surcharge of USD $50.00 will apply to pages with colour figures. Please note that reprints can be ordered, but must be ordered from the editor before issues go to print (with cost of reprints dependent upon number requested, and page length of paper).

Editorial Board of Megadrilogica: Dr. John W. Reynolds, Editor-in-Chief (contact information below), and Associate Editors Dr. Catalina C. de Mischis (Facultad Ciencias Exactas, Físicas y Naturales, Universidad Nacional de Córdoba, Córdoba, República Argentina), Dr. Donald F.
