Iguana, Conservation, Natural History, and Husbandry of Reptiles (ISSN 1098-6324) is published quarterly by the International Reptile Conservation Foundation, a nonprofit, tax-exempt organization, 3010 Magnum Drive, San Jose, CA. Periodical postage paid at San Jose, CA. Editors’ Remarks In addition to feature articles and regular pieces that address responsible husbandry of reptiles, profiles of herpetol- ogists and conservationists, travelogues to herpetologically fascinating destinations, historical perspectives, commen- taries on issues relevant to reptilian biology and conservation, and book reviews, IGUANA has presented short sum- maries of news items (“Newsbriefs”) that feature reptiles and efforts to conserve them and their habitats. With Volume 12 in 2005, we also included summaries of research articles concerning the conservation of reptiles (“Conservation Research Reports”). In this issue, in light of our other focus on natural history, we inaugurate a new section devoted to summaries of research articles dealing with reptilian natural history (“Natural History Research Reports”). The purpose of these short summaries is to create and maintain an awareness of current events and ongoing research addressing issues that readers of IGUANA should find interesting and educational. The research reports in particular are usually extracted from technical journals written with other researchers in mind. However, the investi- gations represent the cutting edge of our knowledge about conservation and natural history of reptiles, and often pres- ent critical information that can lead to new insights and additional research. We have been approached about the possibility of expanding the scope of IGUANA to include amphibians. As a rule, we have resisted those temptations in spite of the reality that global amphibian declines may very well repre- sent the results of events that affect reptiles and other animals in an equally dramatic fashion. However, we frequently do include amphibians in herpetofaunal surveys or travelogues. On occasion, we also may include newsbriefs or research reports about amphibians if the topic is relevant to reptilian natural history or conservation. IRCF members represent a vast cross-section of persons with an interest in reptiles. Included are perspectives from throughout the world, interests in many different kinds of reptiles, and experiences that may range from occa- sional encounters with animals in nature and concerns about a treasured pet to lives dedicated to developing a better understanding of the world around us. Consequently, we eagerly solicit input from subscribers who have found items in the news or in journals that they think may be of broad interest to other readers. If you find such a piece, please submit a copy to an editor or alert us to a source (publication or link).
