Dear all, We wanted to bring to your attention an upcoming theme session in Marine Ecology Progress Series entitled "Tagging through the stages: ontogeny in biologging." If you have papers of interest that examine specific or ideally multiple life stages using tagging techniques, we welcome your submission from now until the 30th of June. The earlier you submit your manuscript the better chance it has at making the theme session. This theme session is a culmination of our workshop at Biologging IV in Tasmania but realize that not everyone was able to attend - attendance is not a prerequisite for submission. For more information on the theme session, to submit a manuscript, or to get more information about MEPS author guidelines, please visit: http://www.int-res.com/journals/meps/theme-sections/forthcoming-theme-sectio... and feel free to email with any questions. Sincerely, Elliott Hazen and Guest Editors
