Nadler Introduction The first announcement for the Vietnamese Journal of Primatology was made at the 21st IPS Congress in Uganda in June 2006. Since that time, and especially with the first issue initially planned for October 2006, preparing the journal allowed little time to breath. It took another six months to clarify finances, receive permits, and obtain original articles from authors. A first-birth can be complicated and protracted and occasionally a forceps is required. We now think, however, that our new-born child is attractive, ready, and can make a useful contribution to primate conservation in Vietnam. The first issue of the journal contains three articles which provide an overview of and basic information about the systematics, phylogeny, distribution, biogeography, threats and status of the Vietnamese primate species. Readers will recognize that the authors of these articles have different opinions on the basic topics listed above and, accordingly, advocate different positions. These differences also reflect that the study of Vietnamese primates is still in its nascent stages. It is the goal of the Vietnamese Journal of Primatology to hasten this process by creating a platform for discussion where new results from the latest studies are published. The journal strives to provide an accurate overview of the current primatological work being conducted in Vietnam. All colleagues involved in editing the journal are involved in and knowledgeable of various primate-related projects in Vietnam. With the involvement of Dr. Christian Roos as the Southeast Asian Primate Coordinator of the IUCN/Primate Specialist Group, the journal creates a connection with this organization, facilitating the efficacious transfer of information with another enterprise involved with Indochinese primates. In addition to the editors and editorial board, the journal received a great deal of help from Nguyen Thi Thu Hien, Project Assistant of the Vietnam Primate Conservation Project, and Jakob Kolleck, one of the head animal keepers at the Endangered Primate Rescue Center. The HAKI Company in Hanoi supported the journal with insight and understanding during its preparation. Finally and importantly, the entire endeavor to publish the journal and to guarantee its continuation was made possible only with great support and commitment by the German Primate Centre. Many thanks for all your support. We hope to meet your expectations. May 2007 Editors 1 LÍi n„i Æ«u Vi÷t Nam Æ≠Óc c´ng nhÀn lµ 1/16 QuËc gia c„ t›nh Æa dπng sinh h‰c (ßDSH) cao.
