The contents of IGUANA, excluding Research Articles, Research Updates, and reprinted articles, may be reproduced for inclusion in the newsletters of other herpetological societies, provided the material is reproduced without change and with appro- priate credits, and a copy of the publication is sent to The International Reptile Conservation Foundation.

Editor’s Remarks Our efforts to expand and diversify the content of Iguana create an ever-increasing demand to obtain new and often rare photographs to enhance content and adorn covers. Locating sources for this material is a daunting task that often takes months of searching just to obtain a single photograph. Several generous photographers have consistently donated photographs in support of our efforts. Their contri- butions have played a major part in shaping the new look of Iguana. The IRCF gratefully thanks: Suzanne L. Collins, CNAH (www.cnah.org), a major contributor of many photographs over the past few years; Thomas Wiewandt, Wild Horizons (www.WildHorizons.com), for spectacular photographs that include this issue’s cover; L. Lee Grismer, La Sierra University, for breathtaking photographs; Joseph Burgess, for photographs and other countless contributions; Joseph Wasilewski, Natural Selections (www.natselections.com), for crocodilian and iguana photographs; and Glenn P. Gerber, CRES (http://cres.sandiegozoo.org) for photographs of West Indian Rock Iguanas.
