Dear Readers: International Journal of Comparative Psychology has just published several new papers on https://submit.escholarship.org/ojs/index.php/uclapsych_ijcp/issue/view/2274 Of interest to members of this listserv, please note the paper by Marulanda et al. and Dudzinski et al. Other articles may be of interest from a comparative perspective. We would also like to draw your attention to a final call for submissions to our final special issue celebrating the Legacy of Dr. Stan Kuczaj. As a developmental psychologist, Stan turned his creative mind to the comparative application of developmental phenomena to marine mammals. Across his 20+ year career studying marine mammals, he conducted both captive and field research on a variety of topics from cognitive psychology to the anthropogenic effects on free-ranging dolphins with collaborators around the world. We hope that this special issue will be of interest to the MARMAM readership and invite your submission by June 15, 2019. Please contact Dr. Heather Hill, with any questions. IJCP is a peer-reviewed, open access, no publication fees journal.
