MMF Scientific Publications

Our scientific work generally focuses on species-level population ecology and conservation biology, with considerable overlap between the two areas. Our major ongoing research programs are focused on manta rays (Manta alfredi and M. birostris) and whale shark (Rhincodon typus). These huge plankton-feeders congregate year-round in the highly productive coastal waters along the southern Mozambican coast, presenting an ideal opportunity for research on these huge yet enigmatic species. Other research projects also examine some of the more unique and/or threatened species found in the area.

 

If you would like a copy of any of these publications, please contact us at media(@)marinemegafauna.org with ‘Request for publication copy’ in the subject line, and a brief description of your background and needs.
