Dear MARMAM & ECS Talk Subscribers, Sadly, this week we lost two icons of the Marine Mammal Community - Dr. Sam Ridgway and Dr. Bill Perrin. Both were two of the first Historical Perspectives participants and they have been added to the HP audio podcast roster as an early Tribute to their legacies in our field. Listen to each reflect on his career and other topics on these newly posted audio podcasts from the HP series on Spotify or Anchor.com <http://anchor.com/>! Also, the 4th issue of volume 48 (48.4) of Aquatic Mammals journal is published online. Further information about the journal can be found at: http://www.aquaticmammalsjournal.org/ <http://www.aquaticmammalsjournal.org/> To submit a manuscript for publication consideration, please visit: http://am.expressacademic.org/actions/author.php <http://am.expressacademic.org/actions/author.php> With regards, Kathleen M.
