SOLAMAC (Sociedad Latinoamericana de Especialistas en Mamíferos Acuáticos) and SOMEMMA (Sociedad Mexicana de Mastozoología Marina) are pleased to announce that the scientific journal of the two societies, the Latin American Journal of Aquatic Mammals (LAJAM), is now an electronic journal. The journal will operate from its new web site (www.lajamjournal.org) and the web pages of SOLAMAC (solamac.org) and SOMEMMA (www.somemma.org) will provide links to it. Since 2002 LAJAM publishes scientific articles on the biology, management and conservation of the aquatic mammals of Latin America. To date it has published seven volumes and Vol. 8 is currently in press. The latter is a special volume on the biology and conservation of neotropical dolphins of the genus Sotalia. It will be the last printed volume of the journal and the electronic version will appear very soon. In addition, editorial teams are currently at work on a special issue on giant otter and a special volume on Tursiops in the Southwestern Atlantic, scheduled to appear in 2012 and 2013, respectively. In preparation for the transition to an electronic publication, earlier this year LAJAM acquired an electronic ISSN (2236-1057) through the Instituto Brasileiro de Informação em Ciência e Tecnologia, and a prefix for Digital Object Identifiers (DOI: 10.5597) through CrossRef. As the electronic journal becomes established in the next couple of years LAJAM will seek inclusion in the various indexation services and in the Science Citation Index, which assigns the Impact Factor. The new site for the journal is an implementation of the Open Journal Systems, an initiative of the Public Knowledge Project. As such, LAJAM will be freely available under the terms of a Creative Commons Attribution License. The new system offers all the services of a modern electronic journal and includes tools like content search, personalization, notifications, social bookmarking, and the option to comment and discuss published articles. The handling of manuscripts from submission to publication will be through the site. Publishing of articles in LAJAM will be free of cost to current members of SOLAMAC and SOMEMMA as a benefit of membership. Everyone is invited to register and create a profile on the site. From its beginning LAJAM has been generously sponsored by Yaqu Pacha (Germany) and Fundação Oswaldo Cruz (Ministério da Saúde do Brasil). It also has received funding from Cetacean Society International, US Marine Mammal Commission, Wildlife Conservation Society, International Whaling Commission, Instituto Aqualie and Petrobras. LAJAM has relied on the effort of the Associate Editors that have been part of the Editorial Board over the years, and on the many researchers that have served as reviewers for the journal. To all of them, thank you! We look forward to your active participation in this new phase of the journal! Doris Oliva President, SOLAMAC Ma.
