Dear MARMAM and ECS Talk subscribers, Apologies to those of you who will receive duplicate emails due to cross-posting. The titles listed below represent the contents of the most recent issue (Volume 46, issue 4, 2020) of Aquatic Mammals that is published online. Aquatic Mammals is the longest running peer-reviewed journal dedicated to research on aquatic mammals and is published quarterly with manuscripts available as published PDFs in real time. Further information about the journal can be found at: http://www.aquaticmammalsjournal.org/ <http://www.aquaticmammalsjournal.org/> In other journal news: 1) At the end of July, we will resume shipping the print copies of Aquatic Mammals to print subscribers; issues 1 thru 4 will be sent in one packet to each print subscriber. 2) We have one Historical Perspectives essay in issue 46.4 and will have one in 46.5. Given these challenging times, we have decided to make all HP essays (from Vic Scheffer’s first essay through current and forward) available for free download to any interested reader. You can access them in the various issues from 2008 through present year. 3) The journal has crept into social media with a Facebook page. Thankfully, Dagmar Fertl, who volunteers her time, uploads posts in advance of each issue’s publication. Authors provide a few sentences and a photo (or 2) about their article as a previous to the full issue being published online. So far, response has been positive. 4) The index files for volumes 44 and 45 (key word and author indices) are now also available for free download from the journal’s index page (under the Issues tab). Thank you for your continued interest in the journal and abstract postings. With regards, Kathleen M.
