Scientific Community

Endang-Species-Res-33-265–279-2017 The CARMMHA consortium will aim to publish over a dozen peer-reviewed manuscripts in scientific journals and also present our findings at scientific conferences. The results of the thematic projects and dolphin health assessments will be integrated into models to predict the recovery trajectory of cetacean populations following the DWH spill.  These models will be of particular interest to researchers in the marine mammal scientific community. Another one of the more broadly applicable areas of research to be pursued by the consortium is the examination of potential oil-related cardiotoxicity in dolphins. This will not only be of great interest to wildlife researchers who are exploring similar effects in other marine species but also to human health researchers due to the similarity of marine mammal and human exposure routes (i.e. inhalation) and conserved mammalian physiology.
