--~~-.... :' ~~;.: ANOLIS NEWSLETTER IV EDITED BY: JONATHAN B. LOSOS and 'GREGORY C. MAYERr ) ./ /' \Or( J ' LJ On the cover: An undescribed Ecuadorean anole, drawn by Laszlo Meszoly. 1991 Division of Amphibians and Reptiles National Museum of Natural History Smith$onian Institution washington, D.C.------------------Foreword A symposium on Anolis biology, which we organized, was held at the 69th annual meeting of the American Society of Ichthyologists and Herpetologists, June 17-23, 1989, in San Francisco. The reasons for the symposium are discussed in Mayer's opening remarks to the symposium, which are reprinted here. In conjunction with the symposium, we felt it would be worthwhile to publish a fourth Anolis newsletter, particularly since it had been 12 years since the third newsletter. All those asked to participate in the symposium, as well as others active in Anolis research, were invited to contribute to the newsletter. In addition, several contributors learned of the newsletter from other sources. As with previous installments, the newsletter is meant to be an informal forum for the presentation of data and discussion of theory pertinent to anoles. In particular, the newsletter serves three functions: 1. to allow investigators to inform others about their current research programs and future plans; 2. to provide an outlet for speculation and theorization perhaps inappropriate for publication in more formal arena; and 3. to present an opportunity for the presentation of data, in whatever format or state of analysis, that otherwise might be lost in the fog of time, never to see the light of day. As in previous newsletters, there is a general request that nothing said herein be quoted without the authors' express permission. Other than basic guidelines concerning margin size, spacing, etc., format and style are entirely the authors' discretion, as the heterogeneity of the contributions will attest. The newsletter is divided into two parts. First, we have included the opening and concluding remarks of the Anolis biology symposium, along with its schedule. The second, and heftier, portion is comprised of the contributions. We are extremely grateful to the Division of Amphibians and Reptiles, National Museum of Natural History, and Dr. George Zug for producing the newsletter. Thanks also to Dr. Sandy Echternacht for organizational assistance and advice. Newsletters have been sent to the contributors. Others interested in obtaining it should contact one of the editors or the Division of Amphibians and Reptiles, National Museum of Natural History, Smithsonian Institution, Washington, D.C., 20560.
